Description

Novel hot end side cut-out press

Technical Field

The invention relates to the technical field of metal stamping dies, in particular to a novel hot end trimming and punching die.

Background

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

The existing design adopts multi-process side punching to achieve the shearing of a semicircular shape. Alternatively, a single punch cuts the edge directly. The multi-process side punching has a plurality of dies, so that the positioning reference has deviation, and the section of a product has steps with unevenness. In the other mode, the two sides of the product are nearly vertical due to the fact that a single punch is adopted for direct punching, and the material is extruded, so that burrs of the product are serious; meanwhile, the multiple processes of processing increase the labor cost and the use of machines undoubtedly, and have certain influence on the economic benefit of a factory. Therefore, it is necessary to design a new hot end trimming and punching die with high production efficiency, good quality and durability.
