Problems solved by technology

If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. In the existing bolt processing plants, the processing methods of cold heading and red punching are more common; for example, the patent publication No. CN111992986A discloses a manufacturing process for bolts. During the processing of the bolts, one end of the steel section needs to be heated, and then the heated end is stamped and formed by a stamping die to form the bolt head. In the existing heating process, the The steel section is placed in the heating furnace, and it is usually necessary to heat the steel section to 900-1100°C. Now the temperature of the steel section is judged by manually observing the color change of the steel section. The judgment is not accurate, resulting in different processing quality of each bolt; The material is inconvenient, especially when the material is cut by manual clamping, there is a great potential safety hazard

Description

technical field [0001] The invention relates to the technical field of bolt processing, in particular to a bolt processing technology and a feeding mechanism thereof. Background technique [0002] Bolts are cylindrical threaded fasteners that mate with nuts. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection . If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. In the existing bolt processing plants, the processing methods of cold heading and red punching are more common; for example, the patent publication No. CN111992986A discloses a manufacturing process for bolts. During the processing of the bolts, one end of the steel section needs to be heated, and then the heated end is stamped and formed by a stamping die to form the bolt hea...
