Description

Technical Field

[0001] This utility model relates to the field of cold heading technology, specifically to a bolt annealing cold heading device. Background Technology

[0002] Cold heading is a processing method that applies pressure to a metal blank at room temperature using a mold, causing it to undergo plastic deformation to obtain the desired shape, size, and properties. For bolt production, cold heading can improve production efficiency, ensure product precision and quality, and save materials. Bolt cold heading utilizes the principle of plastic deformation of metal materials, processing metal wire using a cold heading machine to obtain bolts of the required shape and size.

[0003] After annealing, the wire is cold-headed by a cold heading machine, and a large amount of oil stains are attached to the surface. The oil stains may absorb moisture and dust, forming a corrosive environment on the bolt surface and accelerating the corrosion of the bolt. If the oil is not removed in time, the oily wastewater generated in subsequent cleaning processes will pollute the environment. Utility Model Content
