Inverted Pull Press Feeder Automation Equipment For Sheet Metal Forming


The punch feeder is an automatic device that replaces the manual manual feed for the punch. In the conventional cognition, the feeder is stepped feeding for the punch inlet.


That is, pushing the feed form from left to right or from front to back, only when stamping some very thin materials, the material will be soft and have certain ductility. At this time, if the normal push feeding mode is still adopted.


In the feeding process, the material is easily bent and formed into an arch, which causes the feeding to be inaccurate, and ultimately affects the quality of the stamped product, and the mold damage is easily caused. At this time, the feeder can be installed in a reversed manner.


The air feeder, roller feeder and NC servo feeder commonly used in the stamping industry can be converted into reverse pull type. Of course, the installation of the pull-up type has the preconditions:


1. The tailings and finished products after thin material stamping are not broken. If it is broken, the inverted pull type punch feeder cannot be used, only by adding a guiding device between the normally installed feeder discharge port and the mold. To reduce the bending of the material.


2. For the roller feeder and the mechanical NC feeder, especially the roller feeder, it not only needs to install the loosening rod on the table on the slider of the punching machine but also needs to be powered by the output shaft.


If the punch output shaft is on the side of the feed port, it cannot be installed. At the same time, the press is fed from front to back in many occasions. The pull material needs to be moved from the back to the front. At this time, the loose rod cannot be installed, so the mechanical NC cannot be used. Feeder.


It is precisely because the roller feeder and the mechanical NC feeder are subject to installation restrictions. Therefore, most of the materials used in the drawing are the Ruihui air feeder and the pneumatic NC feeder, and the modification is also very easy.


The air feeder only needs to replace one gas exchange valve. The pneumatic NC feeder has almost no need to make any changes, but with the stamping industry, the precision and stability requirements of the stamping products are getting higher and higher.


Air feeders are far from adequate to meet the needs of customers, so pneumatic NC feeders have become the preferred retractable feed equipment for the stamping industry.
