Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a material forming stamping device. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to make them plastically deform or separate, thereby obtaining workpieces of the desired shape and size. 60% to 70% of the world's steel is plate material, most of which is stamped into finished products.

[0003] Most of the existing stamping forming devices for metal or non-metal materials have the following defects during use: in the prior art, the material needs to be manually placed under the stamping structure during the stamping process. After the stamping is completed, the material needs to be manually removed from the device. During the loading and unloading process, the hands need to be inserted into the interior of the stamping structure, which poses a safety risk. In addition, the stamped material fits tightly to the mold surface, and manual unloading is time-consuming and labor-intensive, affecting the efficiency of the stamping process.

[0004] The vibration caused by the punching devices currently on the market during punching requires the punching mechanism's own structural strength to bear, which results in a higher failure rate of the punching mechanism and reduces the service life of the punching mechanism.

[0005] To this end, we propose a material forming stamping device to achieve automated loading and unloading, reduce risks, improve processing efficiency, reduce the impact force of the mold and workpiece, and extend the service life of the stamping mechanism. Utility Model Content
