Device for automatically feeding material into stamping die

Abstract

The invention discloses a device for automatically feeding a material into a stamping die. The device comprises a driving stamper, a stop pin, a sliding block, a feeding pin, a stop pin floating spring and a feeding pin floating spring; the upper end of the driving stamper is arranged on an upper die, the sliding block is slidably arranged in a lower die, an inclined surface of the sliding block is opposite to and can abut against an inclined surface at the lower end of the driving stamper, the lower end of the stop pin is movably sleeved with the lower die, the lower end of the stop pin abutsagainst the stop pin floating spring, the stop pin floating spring is sleeved with the lower die, the lower end of the feeding pin is movably sleeved with the sliding block, the lower end of the feeding pin abuts against the feeding pin floating spring, and the feeding pin floating spring is sleeved with the sliding block. According to the device, a material guide block composed of the sliding block and the feeding pin is used for pulling the material in the feeding-in direction, the stop pin is used for limiting a material belt to retreat during restoring, due to adoption of the internal material pulling structure of the device, the problem that the material belt is arched is well solved, and the device has the advantages of being low in cost, simple in structure and easy to machine.

Description

technical field [0001] The invention relates to a cold stamping die, in particular to an automatic feeding device in the stamping die. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing. The feeding of the traditional stamping processing strip process must be completed by configuring peripheral feeders, and in There are still certain problems in the realization of ultra-thin material thickness products: when the ultra-thin material thickness products realize multi-station, the strength of the material belt is not good, relying on the feeding method of the feeder in the front part of the mold is prone to arching of the material belt, which affects the accuracy of feeding , easy to cause damage to the mold. Contents of the invention [0003] The object of the present invention is to provide an automatic feeding device in the stamping die wi...
