Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and more specifically to a stamping device for automobile parts processing. Background Art

[0002] Stamping is a forming process that uses 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. When processing some parts of an automobile, stamping equipment is often used for stamping.

[0003] After searching, the existing patent (Announcement No.: CN220805120U) discloses a stamping equipment for automobile parts processing. During use, the rotating motor at the lower end of the mounting frame drives the rotating shaft and the turntable to rotate, so that the unloading arm and the loading arm rotate. Under the action of the controller and the electromagnet, the material pile can be sucked and unloaded. When the loading arm rotates to the material pile, the material is sucked, and when it rotates to the bottom of the punching head, the material is unloaded. After the punching head completes the punching, the unloading arm rotates to the bottom of the punching head to suck the material, and then unloads it onto the buffer pad when it passes above the unloading ramp. This can reduce the idle time of the punching machine, increase the punching speed, and eliminate manual loading and unloading. However, in the process of realizing the present utility model, the inventor discovered that the prior art had the following problems: the above-mentioned stamping equipment adopts an electromagnet adsorption method when grabbing the workpiece, but the magnetic force of the electromagnet can only act on the surface of the magnetic material, and automobile parts are mostly made of non-magnetic materials such as alloys and plastics. When performing stamping processing on non-magnetic materials, it has the defect of being difficult to apply. The overall scope of use of the equipment is relatively narrow, and it is difficult to be widely used.

[0004] In view of this, the utility model provides a stamping device for processing automobile parts. Utility Model Content
