Abstract

Technical Field
[0001] The utility model relates to the technical field of stamping and bending equipment, in particular to an automatic bending device for metal stamping parts. Background Art
[0002] Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging, while bending is the bending of thin plates, and a stamping bending device is required for stamping bending.
[0003] However, the existing stamping and bending equipment cannot form specific parts in one go, and needs to be repeatedly stamped and bent, resulting in low efficiency of stamping and bending of the overall metal stamping parts, which cannot meet the production needs. At the same time, the stamping and bending equipment is relatively sophisticated and complex, which leads to a significant increase in enterprise costs.
[0004] To this end, we propose an automatic bending device for metal stamping parts. Utility Model Content
