Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machine equipment, in particular to a cold heading machine equipment for producing fastener bolts. Background Art

[0002] Cold heading machine is a special equipment that uses the plasticity of metal at room temperature to produce fastener bolts using the cold heading process. Through the cooperation of the die and the punch, raw materials such as wire or bar are directly cold headed into the shape of the bolt head. It has the advantages of high production efficiency and stable product quality. After the bolt is cold headed, if other processing steps such as thread rolling are required, it is necessary to spray lubricating oil on its surface to ensure the accuracy of the thread and the smoothness of the surface.

[0003] When spraying lubricating oil, it is usually necessary to manually wipe the surface of the bolt with lubricating oil, which is time-consuming and labor-intensive. After searching, an efficient bolt cold heading machine device is proposed with announcement number CN220259444U. After the cold heading of the bolt is completed, the device lifts the workpiece to a position consistent with the side nozzle, and then starts the pump body to suck out the lubricating oil, thereby spraying the lubricating oil on the surface of the workpiece.

[0004] However, when the equipment sprays lubricating oil on the surface of the workpiece, due to the lack of blocking and collecting components around the workpiece, excess lubricating oil may be sprayed on the surface of the equipment when the lubricating oil is sprayed on the surface of the workpiece, which may affect the subsequent equipment cleaning or cold heading work, and the lubricating oil that is not sprayed on the workpiece may be difficult to collect for subsequent use, thereby resulting in waste of raw materials.
