Die opening and closing cold header

Abstract

The mold opening and closing cold header comprises a cold header body, a conveying assembly and a smoke removal assembly, the cold header body is provided with a feeding port and a discharging port, the feeding port is vertically upwards arranged towards a feeding assembly of the cold header body, the discharging port is perpendicular to the feeding port, the discharging port is communicated with the feeding port, the cold header body is connected with a smoke prevention assembly, and the smoke prevention assembly is connected with the conveying assembly. The smoke prevention assembly is located above the feeding port and provided with an opening allowing the feeding assembly and the cold heading steel bar to pass through, and the feeding port is larger than the opening. The conveying assembly is connected to the cold header body, one end of the conveying assembly communicates with the discharging port, the end, away from the discharging port, of the conveying assembly is connected with a collecting box, the smoke removal assembly is connected to the top of the conveying assembly and covers the top of the conveying assembly, and one end of the smoke removal assembly communicates with the discharging port and communicates with the smoke prevention assembly. The other end of the smoke removing assembly is close to the collecting box. The method has the effect of reducing the risk that the health of workers is damaged.

Description

Technical field [0001] The present invention relates to the field of standard parts cold heading process, in particular to a kind of open and close die cold heading machine. Background [0002] Cold heading process is a kind of plastic deformation produced by the use of metal under the action of external forces, and with the help of molds, the metal volume is redistributed and transferred, so as to form the required parts or blank processing methods. The cold heading process is best suited for the production of bolts, screws, nuts, rivets, pins and other standard fasteners. The commonly used equipment for the cold heading process is a special cold heading machine. Cold heading machine is a special equipment special equipment for the mass production of nut bolts and other fasteners or standard parts. [0003] In related technologies, the opening and closing die cold heading machine includes the cold heading machine body and the discharge belt, the cold heading machine body is prov...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that during the cold heading process, the instantaneous contact between the mold and the steel cold material will generate high temperature, which will cause the cooling oil or engine oil to evaporate and form smoke. Ease of inhalation of fumes, creating a drawback of increased risk of compromised health of workers
