Automatic Feeding NC Decoiler Straightener Feeder Low Melting Point Alloy Stamping

In the stamping production, the feeder realizes automatic feeding of the stamping equipment. However, when the feeder feeds for a long time, a certain cumulative error will occur. In order to ensure the accuracy of the stamping, a positive pin is required to be guided on the mold.

At this time, the material must be in a relaxed state to correct the accurate position. This is the relaxation that the stamping industry often says; the NC feeders are often divided into two types: a pneumatic NC feeder and a mechanical NC feeder.

Different molds of different products require different relaxation methods, so different models need to be selected. The mechanical NC feeder relaxes quickly and the relaxation distance is short. It is especially suitable for high-speed feeding of short steps, while the pneumatic NC feeder is not limited by stroke. Meet long-term relaxation needs, especially for large molds and non-high speed stamping.

The basic principle of NC feeder relaxation: First, the feeder is relaxed. For the feeding roller, the position of the lower feeding roller is fixed and can only be rotated. The program control servo motor is driven by the timing belt to make the lower roller forward and reverse to feed and return. the goal of.

Mechanical NC feeder relaxation process: NC feeder loosening rod is installed on the slider of the punching machine to move up and down with the slider. When moving downward, it hits the mechanical relaxation bracket, and under the action of mechanically relaxing the rotating shaft, the whole is made. The roller seat moves upwards under the fulcrum of the rotating shaft, so that the upper and lower rollers are separated and separated to realize the relaxing function.

When the slider moves upward, the mechanical relaxation bracket is slowly reset, and the roller seat spring fixing plate is pulled to the left by the return spring, so that the overall roller seat moves downward, and the upper roller and the lower roller can clamp the material to realize feeding.

Pneumatic NC feeder relaxation process: Pneumatic relaxation is controlled by PLC program. The program signal controls the pneumatic solenoid valve to drive the pneumatic relaxation cylinder to pull up, so that the whole upper roller seat moves upwards, so that the upper roller and the lower roller are separated to realize the pneumatic relaxation function.
