Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a continuous mold feeding positioning structure. Background Art

[0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the required parts. The quality, production efficiency and production cost of stamping parts are directly related to mold design and manufacturing.

[0003] A continuous die refers to a cold stamping die that uses a strip of raw material to complete multiple stamping processes simultaneously on a die using several different workstations in one stamping stroke. Each time the die completes a stamping cycle, the material strip moves once at a fixed distance until the product is completed. However, in the traditional stamping production process, if the stamped sheet material is in the form of a long strip, the middle part is likely to bulge during the stamping process, which is not conducive to the continuous stamping of the strip sheet material.
