Description

Hot end combined cone stretching die

Technical Field

The utility model belongs to the metal stamping die field, specifically speaking relate to a tensile mould of hot junction combination awl.

Background

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping, and is called cold stamping die (commonly called 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. Stamping dies are widely available in many forms, and can be classified into a blanking die, a bending die, a drawing die, a forming die, a riveting die, and the like according to the process properties. The forming die is a die which directly copies and forms a blank or a semi-finished workpiece according to the shapes of a convex die and a concave die of a figure, and the material per se only generates local plastic deformation; such as expanding dies, necking dies, flaring dies, relief forming dies, flanging dies, sizing dies and the like, are widely used dies in stamping dies. The shaping is a stamping process which depends on material flow and changes the shape and the size of a process part by a small amount so as to ensure the precision of a workpiece.

The existing hot end cone needs to be punched one by one when being punched, so that the waste of materials is caused, and the production cost is increased.
