The temperature data of the multi-function bus processing machine can be transmitted to the measuring instrument at a low potential by infrared light waves or radio waves.
Because there may be several measurement points, the measured data carries an address identification code for easy control.
The shortcoming of infrared data transmission is that light wave transmission requires space for obstacles, and the transmission distance is short, generally only 3m~5m.
The design has a copper chip integrated bag and an open mouth chip outlet. The slippery slide type can be used to collect and wear copper scraps, so as not to be messy everywhere.
The overall shape is bright, the surface is painted, and it is anti-rust treated by phosphoric acid skin mold, which is wear-resistant and impact resistant. The hand can be directly adjusted to the board seat, which can be used for long and short size standards and unified control specifications.
The azimuth valve control switch is precisely guided, and the position of the punching machine, the curved tool, and the cutting tool are correctly used. Safe and secure foot switch for controlling oil in and out.
The control system can be studied and manufactured separately from the controlled object, and must be treated as a whole to study its dynamics at high speed and the time lag of optical and electrical signals under ultra-high-speed motion control conditions. Impact and its elimination.
In the case of high speed, it is necessary to study the overall linkage of the numerical control system and the control object, the nonlinear control strategy based on the overall power point, and the intelligent control method. The bending unit adopts a closed integral frame structure, which makes it more uniform in processing flat bending and embossing, greatly improving the repeated positioning accuracy in mass production and prolonging the service life.
The bending unit is horizontally processed, making it safer and more convenient to process. The three working positions of the machine can work at the same time without affecting each other, greatly improving the working efficiency. The working stroke of each processing unit can be easily adjusted, reducing the machining auxiliary time and improving the production efficiency. The hydraulic oil tank is welded by thick steel plate. Phosphating treatment, so that the long-term use of hydraulic oil will not deteriorate.
Installing, commissioning (moulding, adjusting blade clearance) or disassembling the mold must be carried out by the person familiar with the machine in accordance with the prescribed procedures. When the machine is in normal working, do not put the handle or a part of the body on the upper and lower molds (blades). In order to avoid accidents, all the sundries and tools should not be placed on the workbench, so as to avoid accidents caused by rolling into the mold or the knife edge. Since the machine can be operated by many people, it is necessary to have a person responsible for directing the production according to the copper row (or aluminum). The thickness of the row) is selected so that the gap between the cutting blade and the die and the radius of the corner of the die must be stopped when the mold is replaced, so as to avoid danger. In operation, when holding the workpiece and waiting for the slider to descend, care must be taken to regularly check the blade and the die. The sharpness of the edge, if the edge is found to be dull, it should be repaired or replaced in time.
When the multi-function bus processing machine uses steel pipe as the hanger of the lamp, the inner diameter of the steel pipe should not be less than 10 mm, and the thickness of the steel pipe wall should not be less than 1.5 mm; the center line deviation of the lamps installed in the same room or place should not be More than 5 mm; three-phase transformers choose the right transformer winding machine equipment is the key to the production of high-performance transformers, foil coil winding machine is the key equipment for winding low-voltage foil coils.
Tensile control and foil strip rectification are key technologies for foil coil winding machines. The foil tension of the existing domestic or imported foil coil winding machine is generated by mechanical friction. The tension is not stable enough, which will result in uneven tightness of the wound coil. The DC resistance between the coils is inconsistent. Defects such as poor.
The larger the transformer capacity used today, the greater the impact on the grid, and the higher the safety required. The quality of the transformer's manufacturing requires not only reliable electrical performance, but also mechanical stability and short-circuit resistance.
The stability is mainly manifested in the manufacturing process control of the coil, that is, the electromagnetic balance of the high and low voltage coils is required, and the axial turns are tight and evenly distributed. Therefore, the coil winding process is required to be axially compressed, and the radial winding is required. The vertical winding machine uses the self-weight of the wire cake, the axial compression is natural, and the tension device is used to control the tension in the radial direction.
The electric hydraulic pump should be used before use:
1. Make sure you have received all the products.
Check all parts for damage or oil leaks. If a similar phenomenon is found to notify the transporter immediately, the transporter is fully responsible for the damage during the transport.
2. Tighten the oil plug when transporting and when not in use. When using the pump, turn the oil filler plug counterclockwise.
3. Check the power supply. The power supply is AC 110V or 220V 50 / 60HZ single phase. Note Use a grounded outlet or plug adapter with a grounded outlet.
4. Check the hydraulic fluid. Check the amount of oil before operation. At this point, the fuel tank should be fully retracted (if it is a pull tank, the tank should be extended). If the tank is fully extended, oil will flow out and flow into the tank to increase the pressure in the tank. Check the oil quantity as follows:
One. Return to the cylinder completely.
Bay check the fuel gauge to see if the oil has reached half of the odometer. If the oil does not reach half of the fuel gauge, the oil is full of oil.
The function of the manual hydraulic pump is to convert the mechanical energy of the power machine (such as electric motor and internal combustion engine) into the pressure energy of the liquid.
Manual hydraulic pump working principle: The cam is rotated by the motor. When the cam pushes the plunger upward, the seal volume formed by the plunger and the cylinder is reduced, the oil is squeezed out of the sealed volume, and discharged through the check valve to the desired place. When the cam rotates to the descending portion of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the oil tank enters the sealed volume under the action of atmospheric pressure. The cam continuously raises and lowers the plunger, the sealing volume is periodically reduced and increased, and the pump continuously draws oil and drains oil.
Hydraulic cable cutter operation instructions:
1. Press and hold the pressure relief lever to retract the blade. Debris caught by steel cables or aluminum is found in the blades and guides and should be removed.
2. Pull out the latch, open the cutter head, and place the cutting material inside the cutter head.
3. Close the cutter head and fasten the lock pin. Do not apply force to the pump handle if the lock pin is not fully inserted, otherwise the shaft will break.
4. Shake the pump handle, clamp the material to be cut and keep it as straight as possible. When cutting thick steel cables (such as steel-cored aluminum stranded wires), it is recommended to shake the pump handle a small amount, which is easy to cut (Note: continuing to shake the pump handle after cutting will damage the blade or cutter head).
5. After the cut is complete, the pressure relief lever should be depressed to return the blade to its bottom.
6. Remove the debris adhering to the steel cable, copper or aluminum in the blade and the guide groove, which is convenient for the next cutting (Note: If the debris is caught in the guide groove, it will hinder the movement of the blade).
Notes on hydraulic cable cutters
1. There is an impact when cutting hard materials. The cutting can be done step by step.
2. This tool cannot cut piano lines and P.C. strands.
3. Tools should be used within the cutting range listed in the specification. If the material to be cut requires more than 18 kg of pumping power, it will cause abnormalities to materials and tools. At this point, stop pumping oil immediately and check if the material to be cut is within the cutting capacity and the tool is working properly.
4. If the tool needs to be used below 5 °C below zero, the tool should first be warmed to approximately 10 °C to allow the hydraulic system to work smoothly.
5. Avoid storing tools in damp areas. Wipe the tool with a tarpaulin and lubricate the shaft.
6. When you are not using the tool, you should put it in the toolbox.
7. If the strands of the strand or cable are blocked between the insert and the cutter head so that the insert cannot be retracted, tap the top of the piston while pushing the pressure relief lever.
Hydraulic cable cutter Note:
1. Do not cut the P.C. line or the piano line.
2. Do not cut lines beyond the cutting range.
3. The pump oil force must not exceed the maximum allowable value of the tool.
Manual hydraulic clamp
Manual hydraulic clamp is suitable for high altitude or ground operation. It is used for crimping of copper and aluminum terminals of power distribution lines and distribution lines at the workshop. It is equipped with automatic pressure relief device, safe and reliable, light weight, after terminal crimping The shape is a regular hexagon, with good electrical conductivity and a wide range of crimping.
Structural principle of manual hydraulic clamp
The crimping pliers are composed of a fuel tank, a power mechanism, a reversing valve, a pressure relief valve and a pumping mechanism. The pumping mechanism consists of an oil pump body, high and low pressure oil outlet holes, eccentric shafts, eccentric bearings, driven gears and A pair of high-pressure oil pump and a low-pressure oil pump are constructed, the oil pump body is suspended on the fuel tank cover, and the high and low pressure oil outlet holes are opened on the oil pump body, and are connected with the pressure relief valve oil passage, the eccentric shaft is longitudinally disposed, and the upper end is pivoted The center of the oil pump body is fixed with an eccentric bearing at the lower end. The driven gear is fixed on the top of the eccentric shaft and coupled with the power mechanism. The high and low pressure oil pumps are suspended on the oil pump body, and each has an action member that is in contact with the eccentric bearing. The pump chamber of the low pressure oil pump is respectively connected to the high and low pressure oil outlet holes. The connection between the pump oil mechanism and the power mechanism is a vertical connection, which can make full use of space and reduce the floor space, which is beneficial to operation and transportation; the pump oil form of the high and low pressure oil pumps is changed into an eccentric bearing actuation form, and has a structure. Simple, few parts are good for assembly
How to use manual hydraulic clamps
1. First check if the crimp terminal and the wire specifications match.
Manual hydraulic clamp
2. Select the mold to be pressed, for example, the terminal size of 240mm2 to be pressed, then select the 240mm2 upper and lower mold.
3. Insert the mold into the piston and mold holder.
4. How to use the pump: Tighten the oil return switch clockwise and shake the handle repeatedly to look at the mold. When the upper and lower molds touch one place, it means that the pressure is over, if the user does not pay attention to continue to shake. The pump has a "beep" sound, which is opened by the safety protection device, and the piston stops moving forward. At this time, the oil return switch should be turned counterclockwise, and the piston returns to the original position.

Daily maintenance and maintenance of press punching machine
1. Keep the tool head clean to avoid stains and chips. Use a lubricant cleaning tool if necessary.
2. Please apply for the anti-rust oil for the product regularly. Avoid touching the tool with water or other solvents.
3. Please replace the hydraulic oil connected to the pump regularly. Doping particles in pumped working oil is the most common cause of product failure.
4. Do not lift the tool with a pressure hose or pipe joint, or throw it to the floor, or put it in a tool box.
5. Do not place the product in a place where it is exposed to high temperatures, high humidity, or exposed to direct sunlight for long periods of time.
Manipulation principle of hydraulic punching machine: The punch with the same size as the 1/2′′ conduit hole is usually used to enlarge the positioning hole; therefore it is called “stepwise hole expanding method”. After the positioning hole is enlarged, use 3/4′′ Pull the screw to complete the final punching.
1. Drill a 1/2" locating hole with a Greenlee Kwik-stepper step drill.
2. Turn the pressure relief valve knob counterclockwise to fully extend the piston. A 3/4" x 3/8" adapter, 3/8" screw, support ring and 1/2" catheter mold were mounted and inserted into the locating holes.
3. Twist the 1/2" channel-shaped punch onto the screw and tighten it. If the punch is not tightened, it will not be completely punched.
4. Twist the pressure relief valve handle clockwise. Rotate the punch to the optimum position and then start pumping the pump handle until the punch passes completely through the material. If the punching is not complete, check that the installation of steps 2 to 3 is in place. Note: Do not run the pump after the piston has stopped moving. Failure to do so will damage the drive and internal parts and may harm nearby personnel.
5. Twist the relief valve handle counterclockwise to remove the punch, mold, screw, and adapter. 6. Install the 3/4′′ screw and select the appropriate size of the punch and die, repeat steps 4 and 5.
Manual hydraulic crimping pliers are widely used by national power companies, railway systems, and construction units. The specific operation methods are as follows:
1. Pull out the mold release button and attach half of the mold to the top of the tool head. After centering, release the button.
2. Push the mold release pin and insert the other half of the mold into the bottom of the tool head. The mold will be held in place by the stop pin.
3. The tool head can be rotated freely to allow the operator to view the mold, load the fittings and crimp. The tool head can be rotated 180 degrees (but not when there is hydraulic pressure).
4. Put the fittings into the tool head for the first time.
5. Shake the pump handle until the mold closes or the relief valve in the crimping tool acts and sounds (the cracking sound from the simultaneous reduction in the force required to rock the pump handle can be observed). If the mold is still not clearly visible, continue to shake the pump handle until the relief valve operates. If the mold cannot be closed, it may be due to: a) the application of the tool does not meet the design requirements. b) The pump pressure is less than 700 kgf/cm2 (10,000 PSI). c) The mold size is not properly selected.
6. Turn the pump handle clockwise and stop in the open position to relieve the tool and then place it in the closed position. Note: Fingers should be kept away from the mold and piston during crimping. 7. Slide the crimping pliers to the next bite position and slightly overlap the previous crimp as required.
First, the power tool hydraulic pump use steps:
1. Connect the wired remote control switch on the hydraulic pump to the connector on the hydraulic pump.
2. Connect the power plug to a 220V power outlet. (110V)
3. Combine the high-pressure oil pipe with the hydraulic quick coupling on the hydraulic pump, and then join the hydraulic tool and install the mold to check whether the joint parts of various tools are true.
4. Before the official use, you should first press the "DOWN" (down) switch on the switch, first relieve the pressure and then press the "UP" switch, because the machine is semi-automatic for inching work. If the pressure is applied (tool piston forward), the piston can be kept in position. It is automatically stopped when the completion of the correct crimping is completed, thus ensuring the quality of the crimping.
5. When the action is completed, press the switch under “DOWN” to release the pressure and return the tool piston to its original position.
Second considerations for power tool hydraulic pump:
1. There is a venting hole on the oil storage tank of this machine. When transporting, pull the column bolt of the vent hole to the left or right to prevent the hydraulic oil from leaking out. When using, the column should be bolted to facilitate the exhaust.
2. The pressure of this machine has been set to 700kgf/cm2 before leaving the factory. If it is not necessary, it can't be adjusted freely.
3. Use the power cord to avoid being too long to avoid voltage drop and affect the efficiency of the hydraulic pump.
1. Connect the pump, pressurize the joints and the tubing to remove dust and other dirt. If a forced connection is made, the gasket inside may be damaged, resulting in oil leakage.
2. Make sure the connection is correct. After the connection is completed, check if the ring on the female connector can rotate freely. If the connection on the side of the pressure relief is unreasonable, even if the pressure is connected to the high pressure, the pressure connection will be affected, resulting in damage to the seal or direct damage to the pressure joint. In order to avoid this situation, our pressure fittings are fitted with safety valves. Pay attention to this if you use pressure connectors from other manufacturers.
3. Generally, when you disconnect the remote control cable, you should use the plug (including the wireless remote control) by hand, and do not pull the remote control cable to disconnect it.
4. Hydraulic oil is generally used in the list. Brake oil cannot be used under any circumstances, which can damage the gasket and affect pump performance.
Operational Procedures for Power Tool Hydraulic Pipe Bender
1. Before operation, first check whether the lubrication points of the bending machine are short of oil, whether the moving mechanism is loose, and whether the safety protection device is reliable.
2. Start the bending machine oil pump, whether the system pressure is kept within the specified range. If it is high, it will damage the hydraulic components and waste power. If it is too low, it will affect the work.
3. Adjust the position and required angle of the part.
4. Adjust the positioning of the machine to the required length.
5. Adjust the vertical lifting rail so that the guiding mold pressing cylinder advances to clamp the tight iron pipe.
6. The clamping die clamping cylinder can clamp the iron pipe.
7. Normal operation Put the workpiece into the bending mold, and the front end is in contact with the positioning, and the foot switch can be stepped on.
8. When operating the pipe bending machine, the idea should be concentrated. It is forbidden to put the hand or other items into the work area. In case of emergency, press the emergency stop button, then turn the twist switch to the manual position, and manually reset. If a malfunction occurs, repair it in time.
After the work, cut off the power supply and clean and lubricate the work
