After the installation of the punch NC servo feeder, it is also necessary to make a series of adjustments to the equipment according to the width, thickness, feeding step and mold requirements of the actual stamping material.
The adjustment of the punch NC servo feeder includes:
1. Adjustment of feeding height
The adjustment of the feed height is the basis for ensuring that the material passes through the die smoothly and is stamped correctly. Here's how to adjust it:
1. Loosen the adjusting screws on the mounting plate of the NC servo feeder. This step is to unlock the height adjustment function and make the adjustment process smoother.
2. Adjust the feeding height. It needs to be adjusted according to the height of the mold line of the actual mold to ensure that the output end of the feeder is consistent with the height of the mold inlet. If the feeding height is too low, the adjustment screw should be rotated clockwise to make the machine rise; On the contrary, if the feeding height is too high, turn the adjustment screw counterclockwise to make the machine lower.
Second, the adjustment of the material width feed stop
The adjustment of the material width feed stop ensures the correct guidance and positioning of the material, preventing the material from deflecting during the feeding process. The adjustment steps are as follows:
1. Adjust according to the width of the material. The width of the feed stop wheel is set to be about 2 mm wider than the width of the material actually used, so as to facilitate the smooth feeding of the material and reduce the possibility of deflection.
3. Adjustment of the pressing spring pressing (thickness).
The key to the adjustment of the compression spring is to ensure that the material does not slip during the feeding process, and at the same time to avoid excessive pressure on the material, resulting in damage. Adjustment points include:
1. Adjust the pressing strength according to the width of the material. Adjust the strength of the pressing spring to ensure that the compression force of the left and right springs is equal to avoid deflection of the material during the feeding process.
Fourth, the adjustment of the feeding angle and the relaxation angle
Correct adjustment of the feed angle and relaxation angle is the key to smooth feeding and precise positioning. The adjustment is carried out according to the specific needs of the punch and die, and is completed by adjusting the feeding angle cam signal and the relaxation angle cam signal connected to the NC servo feeder and the punch.
5. Adjustment of feeding length and frequency
Depending on the stamping process, the length and number of feeds can be set differently. Here's how to adjust it:
Set the feeding length and number of times on the touch screen. Normally, if there is only one feed length, only one length is set, the number of times is set to 1, and the number of segments is set to 1. If multiple feeding lengths are required, set multiple sets of lengths, times and segments according to requirements.
The adjustment of the NC servo feeder is a meticulous and professional process, which involves the adjustment of many aspects, including the feeding height, the width of the feed stop, the pressing spring (thickness), the feeding angle and the relaxation angle, and the feeding length and frequency. The operator needs to carefully adjust the parameters according to the actual stamping materials, die needs and process characteristics.
