Why does the material go backwards during the production of the automatic punch feeder? What are the reasons? Let's first understand that the automatic punch feeder and servo feeder are also called NC computer feeders, which realize the precise feeding of stamping materials through the servo electric control box, servo motor drive and feed roller drive. At present, it is the most commonly used feeder in the stamping industry.

So why does the material go backwards when the servo feeder is produced? The main reason is that the servo feeder's loose angle adjustment error is caused by the operator's failure to operate correctly or the setting error. If the relaxation angle is too large, the gap between the roller materials is too large, which causes the material to fall back. There are two ways to relax the servo feeder, mechanical relaxation and pneumatic relaxation. Regardless of which relaxation method, it must be based on the thickness of the material and the requirements of the equipment. The situation is adjusted correctly.

In addition, the automatic feeder of the press has been used for a long time, because the equipment has been running for a long time, and it cannot be customized for maintenance. Foreign matter and debris are mixed in the servo feeder equipment, resulting in damage to the equipment parts and wear. It is also a common occurrence of our servo feeders. One of the causes of the abnormal problem.

In addition to the servo NC feeder control system, the automatic feeding machine's mechanical principle is to drive the servo roller to rotate periodically through the eccentric wheel, connecting rod and one-way device, intermittently at a certain speed. Send the material in. In actual use, the punch slider moves first. During the down punching process, the relaxation bracket hits the extension of the Palin, which makes the Palin rotate, and the lower end of the Palin is lifted by an angle, so that the lower end of the Palin will lift the adjustment seat. The raw material belt can be sent between the upper roller and the lower roller, and then the eccentric shaft is rotated by the hand wheel, thereby further adjusting the front-to-back distance between the upper roller and the lower roller.

After adjusting, lock the locking bolts, and then the punch slider rises, and the return device acts on the shaft returning position, so that the raw material belt is clamped between the upper roller and the lower roller to complete the clamping of the raw material belt. After the clamping of the raw material belt, the stepping drive mechanism of the automatic feeder of the punch press opens and closes: the eccentric disk rotates, which drives the connecting rod to rotate, and the connecting rod drives the drive shaft to rotate back and forth. Rotating, the lower roller and the upper roller rotate synchronously, so that the raw material belt is stepped forward.
