Description

Technical Field

[0001] The utility model relates to the technical field of cold heading components, in particular to a bolt progressive cold heading mechanism and cold heading equipment. Background Art

[0002] Bolt cold heading equipment is a special equipment used to manufacture fasteners such as bolts. Bolt cold heading equipment mainly forms bolts through cold heading process. At room temperature, it uses the plasticity of the metal and the mold to apply pressure to the metal blank to cause it to undergo plastic deformation in the mold cavity, thereby obtaining bolt parts of the required shape and size.

[0003] The cold heading process can achieve continuous and rapid production, greatly improving the production efficiency of bolts. Compared with traditional cutting processing, cold heading equipment can produce a large number of bolts in a short time. It also has the advantages of high material utilization and good product quality.

[0004] The progressive cold heading machine is a device that gradually performs cold heading processing on metal materials through multiple stations. First, the raw material is sent to the first station for preliminary upsetting or shaping. Then, as the material is transferred between different stations, head forming, thread forming and other operations are carried out in sequence. Each station only completes a part of the processing task and gradually realizes the complete shape of the bolt.

[0005] During the progressive cold heading process, the metal material undergoes severe plastic deformation in the mold, which generates great friction. Therefore, lubricating oil is added to the mold during cold heading to form a lubricating film between the mold and the metal material, thereby reducing friction resistance, reducing mold wear, and extending the service life of the mold. In the prior art, the bolts are usually placed in the equipment for cleaning after the cold heading is completed. During the discharge process, the bolts covered with lubricating oil will contaminate the equipment, causing cleaning difficulties. Utility Model Content

After cold heading is completed, the adjusting mechanism drives the cleaning mechanism to move up to surround the bolts, and the water supply mechanism supplies water to clean the bolts, achieving full-round cleaning and avoiding oil pollution of the machine and causing difficulties in cleaning.

[0048] Among them, the feeding mechanism includes a feeding plate 3, feeding holes 4, a threaded rod 5 and a motor 6. The feeding plate 3 is slidably connected to the support table 1.
