Cold heading system for formed welding nut and machining process

Abstract

The invention discloses a cold heading system for a formed welding nut and a machining process. The cold heading system comprises a machine frame, a lower die set is fixedly installed on the surface of one side of the machine frame, swing shafts are hinged to the surfaces of the two ends of the machine frame, lifting telescopic rods are hinged to the surfaces of the swing shafts, swing plates are fixedly installed on the rod heads of the lifting telescopic rods, a long-strip-shaped through groove is formed in the surface of each swing plate, a sliding plate is slidably installed on the side face of each long-strip-shaped through groove, an electromagnet is fixedly installed on the surface of one side of each sliding plate, a right-angle side plate is fixedly installed on the surface of the other side of the machine frame, cold heading telescopic rods are fixedly installed on the surfaces of the two ends of the right-angle side plate, a cold heading plate is slidably mounted on the rod head of each cold heading telescopic rod, and an upper die set is fixedly mounted on the surface of one side of each cold heading plate. Therefore, the use convenience and stability can be greatly improved, and the cold heading forming accuracy and efficiency are guaranteed.

Description

technical field [0001] The invention relates to the field of nut processing, in particular to a cold heading system and processing technology for forming welded nuts. Background technique [0002] During the processing of welding nuts, cold heading equipment is mostly used to form the cut wire through multiple cold headings to process nut blanks, and finally carry out thread finishing and forming. [0003] However, in the existing welding nut cold heading equipment, multiple molds are installed separately. After one process is completed, the intermediate blanks are transferred to the next mold in batches. This not only greatly reduces the processing efficiency, but also easily causes different processes. The blanks are mixed with each other, which affects the efficiency and safety of precise cold heading. At the same time, multiple cold heading processing of a nut is not conducive to controlling the angle and depth of the feeding and feeding, and affects the quality of cold ...

[0003] However, in the existing welding nut cold heading equipment, multiple molds are installed separately. After one process is completed, the intermediate blanks are transferred to the next mold in batches. This not only greatly reduces the processing efficiency, but also easily causes different processes. The blanks are mixed with each other, which affects the efficiency and safety of precise cold heading. At the same time, multiple cold heading processing of a nut is not conducive to controlling the angle and depth of the feeding and feeding, and affects the quality of cold heading, which needs to be improved.
