Although there are many kinds of punches that can be matched with NC feeder, the installation and commissioning methods are basically the same, which is mainly divided into five steps:
1. Fix the mounting plate of the NC feeder on the side of the lower table of the punch. Pay attention to align the mounting plate of the NC feeder with the middle of the T-groove on the table, drill four M16 tooth holes on the side of the table according to the hole position on the mounting plate, and then fix it.
2. Lift the head of the NC feeder with a forklift or crane, align and fix it in the keyway of the mounting plate on the table, and fix the head with supporting bolts.
3. The sliding plate of the fixed NC feeder usually has an adjustment amount of about 100mm for adjustment. After the die is installed on the punch, loosen the two bolts on the sliding plate, adjust the bolts fixed on the mounting plate, adjust the feeding height of the NC feeder according to the height of the die, and then fasten the bolts.
4. Set the relaxation of NC NC feeder. If the installed feeder is a pneumatic feeder, it is necessary to connect the release signal line on the cam group of the punch, and adjust it to make the NC feeder in the release state when the stroke of the punch is close to 180 degrees. If the installation is a mechanical NC feeder, the release rod shall be installed at the corresponding position on the sliding block of the punch. (special note: if the stamping material is thin and there is a certain distance between the supporting plate and the lower die, a guide plate must be installed to avoid deflection during feeding by the feeder)
5. Connect the feeding signal line connected with the cam of the punch, and set the slider of the punch to start feeding at 270 degrees. If the punch has no cam group, it is necessary to add a microswitch or proximity switch to realize the automatic feeding and relaxation of the feeder.
