Description

Technical Field

[0001] This utility model relates to the field of metal fastener forging technology, and in particular to a forging device for metal fastener production. Background Technology

[0002] Metal fastener forging is a process that uses a die to apply pressure to a metal blank, causing it to plastically deform and thus forming a high-strength fastener. The forging process can eliminate defects such as internal pores and cracks in the material, and improve the fatigue resistance and mechanical properties of the fastener through grain refinement. It is widely used in fields such as construction and machinery manufacturing.

[0003] Currently, existing forging equipment typically requires manual blanking of fastener blanks. Since the blank temperature is usually high, the blanking process is dangerous for workers. In addition, a large amount of oxide scale debris is generated during the forging process. This debris remains in the mold and is difficult to clean, which also affects the forging effect.
