Description

Technical Field

[0001] This application relates to the technical field of cold heading machines, and particularly relates to a simple cold heading machine. Background Art

[0002] Cold heading is a metal plastic processing technology. At normal temperature, using the plasticity of metal materials, pressure is applied to metal bars or wires through a mold to cause local plastic deformation, so as to obtain parts or blanks with the required shape, size and performance. A cold heading machine is a metal processing equipment used to upset and forge metal wires or bars through a mold at normal temperature.

[0003] It is found that the publication number: CN209288200U discloses a cold heading machine. In this technology, "a discharge chute is provided on the cold heading machine body, and a material receiving cylinder is provided at the bottom of the discharge chute. The material receiving cylinder includes an open-top round box, and a detachable hopper protrudes in the middle of the open-top round box. The hopper includes a funnel plate, an aggregate frame, an oil collecting hopper connected in sequence from top to bottom, etc. The technical solutions have the technical effects of being able to separate the waste residue of fastener oil and the residue therein, reducing the number of workstations, being able to separate fasteners and oil, and being able to quickly separate and take away fasteners and the oil stains seeping from them, saving processes, completing two steps at one time, and improving work efficiency".

[0004] Regarding the above related technologies, the inventor believes that for the existing cold heading machines, the upper and lower die structures are not convenient for replacement, so only workpieces of a single specification can be processed, with great limitations.
