Stud Manufacturer is divided into many processes when making high-strength bolts, namely cold drawing-spheroidizing annealing-mechanical dephosphorization-pickling-cold drawing-cold forging forming-thread processing-heat treatment and finally to inspection. Each step of the high-strength bolt is very important and indispensable. Take the cold forging process as an example. Under normal circumstances, the forming of the head of the high-strength bolt is processed by cold forging plasticity, and there are very few cases. It is processed by cutting. But compared with cutting, the metal fiber, that is, the metal wire that is often said, will be continuously distributed along the shape of the product, without cutting in the middle, so the strength of high-strength bolts is improved, especially the mechanical properties of high-strength bolts are obviously outstanding.

  The cold heading forming process of high-strength bolts also summarizes the cutting process and forming, and it is also divided into single-station one-click and double-click cold heading and multi-station automatic cold heading. Only one automatic cold heading machine can perform multi-station processes such as stamping and upsetting, extrusion and diameter reduction in multiple forming dies. Sometimes a single station is used. Regardless of whether it is a multi-station or single-station automatic cold heading machine, the processing characteristics of the original blanks used are the size of the bar material with a length of five to six meters or the size of a wire rod with a weight of 1,900 to 2,000 kg. To make the decision. That is to say, the cold forging forming process of high-strength bolts is characterized in that the cold forging forming does not use pre-cut single-cell blanks, but uses the oil rod material and the wire rod wire of the automatic cold forging machine itself to obtain and upset. Fasteners Suppliers use raw material in some cases.
