A preformed module structure in a lock bracket mold

Abstract

The invention relates to a pre-forming module structure for manufacturing a lock-bracket die. The pre-forming module structure is composed of an upper module, a lower module and a stripping module. The pre-forming module structure is simple and convenient to use. The product machined though the pre-forming module structure is small in internal stress of a forming face and a punching face, and smooth and neat in surface. Meanwhile, the pre-forming module structure can be used for rapidly completing pre-forming of the product, in this way, the machining time is shortened, time and labor are saved, the human resource cost is lowered, the automation degree is high, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a mold structure, in particular to a preformed module structure in a mold for making a lock bracket. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. With the development of stamping technology, the stamping parts given by customers are becoming more and more complex, and the product requirements for stamping parts are also getting higher and higher. Many stamping parts need to be independently designed for production. The existing technology is often used for the preforming of complex workpieces. Each stamping surface is stamped and preformed separately in sequence. This method of stamping preforms in sequence will have a large internal stress on the product itself, which will easily lead to product deformation. A...

With the development of stamping technology, the stamping parts given by customers are becoming more and more complex, and the product requirements for stamping parts are also getting higher and higher. Many stamping parts need to be independently designed for production. The existing technology is often used for the preforming of complex workpieces. Each stamping surface is stamped and preformed separately in sequence. This method of stamping and preforming in sequence will have a large internal stress on the product itself, which will easily lead to product deformation. At the same time, each stamping and forming surface of the workpiece bears the stamping force independently, resulting in The workpiece is unevenly stressed, and the surface is prone to scratches or scratches, which affects the flatness of the product surface
