Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, and in particular to a U-groove stamping equipment. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation to obtain workpieces of the required shape and size. With the rapid development of science and technology, workpiece stamping technology is also constantly improving, which plays an important role in the innovation and design of equipment for U-shaped channel iron stamping production.

[0003] A search revealed Chinese Patent Publication No. CN218638301U, which discloses a U-shaped groove stamping device for textile machine stamping parts. This patent includes a cylinder, which is bolted to a cylinder mounting platform. The cylinder mounting platform has three circular holes, and a cylinder push rod connected below the cylinder passes through the central circular hole in the cylinder mounting platform. A U-shaped stamping plate is welded to the other end of the cylinder push rod. The top of the U-shaped stamping plate is disc-shaped, and a U-shaped protruding strip is provided below the disc. A mounting bracket is welded into each of the other two circular holes in the cylinder mounting platform. The device includes two fixed sleeves, each connected to a threaded rod. This solution addresses the problems of traditional stamping equipment where the lack of fixing during the process leads to warping and upward flipping of the stamped parts, compromising their integrity. It also prevents scrap from escaping during stamping, hindering recycling and wasting resources. Furthermore, existing U-groove stamping equipment requires manual unloading after stamping, making it difficult to avoid jamming, compromising safety, and impacting production progress. Additionally, the workpiece may move back and forth during stamping, affecting the stamping quality, thus its practicality needs improvement. Utility Model Content
