1. To ensure the best die gap, the die gap refers to the sum of the gaps on both sides when the punch enters the lower die. Different plate thicknesses and different materials should use lower dies with different gaps. Selecting the appropriate die gap can ensure good punching quality, reduce burrs and collapse, keep the sheet flat, effectively prevent material stripping, and prolong the life of the die.
2. Try to avoid rainy days, or reduce the use of busbar processing machines in wet seasons, and keep the indoor monotony and not be affected by rain. If conditions permit, you can cover it with a waterproof cover.
2. Due to the pressure and heat during punching, the fine particles of the sheet will be bonded to the surface of the punch, resulting in poor punching quality. To remove the sticky material, it can be polished with fine oil stone, and the polishing direction should be the same as the direction of the punch movement.
The above three points should be paid attention to in the selection of hydraulic oil for busbar processing machines. Our company specializes in the production of CNC equipment such as busbar processing machines. Those in need are welcome to inquire and order, and look forward to your negotiation and cooperation.
The busbar processing machine can perform operations such as bending, punching, shearing, flat bending, etc. on busbars, steel bars, etc., and can also perform work such as pipe bending. Then you know that there are certain requirements for the installation environment for the busbar processing machine to work normally. The following is a simple guide for you to understand.
3. If a lot of holes are punched on a plate, first punch every other hole, and then return to punch the remaining holes, which effectively relieves the stress accumulation during sequential punching in the same direction, and also makes the two groups of holes in the front and rear. The stresses cancel each other out, thereby reducing the deformation of the sheet.
In order to improve market competitiveness, the design of high-precision and high-efficiency CNC busbar processing machines has gradually been put on the agenda. The positional accuracy of the busbar bending machine in the processing process is mainly studied, and a complete control scheme is designed to improve the bending accuracy. Taking the KMW427J hydraulic numerical control busbar processing machine as the sample and the copper busbar as the test material, through the analysis of the springback mechanism of the busbar during the bending process, the experimental plan was developed, and the PLC control program was prepared. On the die of the bending mechanism, as a feedback device for the real-time position of the die, the displacement of the die stroke is collected by the grating ruler, which is directly fed back to the PLC, and the displacement is started and stopped by the digital quantity obtained by the PLC.
4. Try to avoid punching too narrow strips. When the die is used for punching a sheet with a width smaller than the thickness of the plate, the punch will be bent and deformed due to the action of the lateral force, and the gap on the other side will be too small or the wear will increase. In severe cases, the lower die will be scratched and the upper and lower dies will be damaged at the same time.
Second, the CNC system position loop failure
5. Timely sharpening can effectively prolong the service life of the mold. When the edge of the die is worn to produce an arc with a radius of about 0.10mm, it needs to be sharpened. When sharpening, the amount of each grinding is 0.03~0.05mm, and the grinding is repeated until the punch is sharp. After sharpening, use whetstone to polish the edge to remove burrs, and apply lubricating oil after demagnetization.
3. To maintain the office current of the motor of the CNC bus bending machine, but the large
6. Regularly check the alignment of the upper and lower die bases of the busbar processing machine. If the centering of the die position of the punch is not good, the die will be rapidly passivated and the processing quality of the workpiece will be deteriorated. Check and lubricate the die holes and guide keys on the turntable, and repair them in time if they are damaged; clean the lower die seat of the turntable so that the lower die can be installed accurately, and check the wear of its keys or keyways, and replace if necessary.
