Replacing the cutting die of a CNC punching machine is an important maintenance process. The following are clear steps and precautions for replacing the cutting die:
###1、 Preparation work
1. * * Confirm the model and size of the knife mold * *: Ensure that the new knife model to be replaced has the same number and size as the original knife mold to avoid unnecessary trouble.
2. * * Prepare required tools * *: Prepare the necessary tools, such as wrenches, wrenches, special tools, etc., for smooth replacement.
3. * * Power off, shut down, and disconnect the air source * *: Before replacing the cutting die, ensure that the CNC punching machine has been powered off, shut down, and disconnected from the air source to ensure safety.
###2、 Dismantling old knife molds
1. * * Open the baffle * *: Find the baffle on the CNC punching machine and open it to access the cutting die area.
2. * * Fix the mold on the machine tool * *: Press the mold on the machine tool tightly to ensure that it will not move during the disassembly process.
3. * * Unscrew the fixing screws * *: Use a wrench or wrench to unscrew the screws that fix the knife mold one by one, and place the screws in the box to avoid loss.
4. * * Take out the old knife mold * *: Take out the old knife mold from the clamp and carefully place it on the dedicated mold car or parallel shim.
###3、 Install a new blade mold
1. * * Confirm new knife mold * *: Check the model and size of the new knife mold to ensure it is the same as the one to be replaced, and confirm that it is intact and undamaged.
2. * * Place new knife mold * *: Carefully place the new knife mold on the clamp and tighten the screws with a special tool. Be careful not to tighten the screws too tightly to avoid damaging the blade mold or gripper.
3. * * Adjust position * *: Use a clamp to hold the cutting die, move it onto the machine tool workbench, pay attention to positioning, and adjust the position by hand.
4. * * Close the baffle * *: After confirming the correct position of the cutting die, close the baffle and release the mold on the machine tool.
###4、 Inspection and testing
1. * * Power on Test * *: Reconnect the power and air source, and start the mold test. Observe whether the blade mold is installed correctly and working properly.
2. * * Punching test * *: Conduct a punching test to check whether the working effect of the cutting die is reliable. If necessary, the position or angle of the cutting die can be adjusted to achieve the best punching effect.
###5、 Precautions
1. * * Safe operation * *: When replacing the cutting die, pay attention to your own safety, do not touch the moving parts on the machine tool, and ensure that the machine tool is in a stopped state.
2. * * Tighten screws * *: When fixing the knife mold, make sure the screws are tightened, but not too tight, to avoid damaging the knife mold or clamp.
3. * * Cleaning Workbench * *: After replacing the cutting die, clean the workbench to ensure that there are no remaining debris or tools to avoid affecting the normal operation of the equipment.
The above steps and precautions are applicable to the tool mold replacement process of most CNC punching machines. However, different models and brands of CNC punching machines may have different operating details and requirements. Therefore, in actual operation, please refer to the equipment’s user manual or consult professional advice.
