There are many processes for manufacturing ANSI B18.2.1 bolts, and each process has its own strict operating standards. If problems occur at any point, it will have a serious impact on the next process. Take a very real example, that is, when you eat, accidentally put more salt, and finally affect your personal appetite and in the hotel, this is the brand that affects this point.

The ANSI B18.2.1 bolts are subjected to multiple processes such as cold drawing - spheroidizing annealing - mechanical phosphorus removal - pickling - cold drawing - cold forging forming - thread processing - heat treatment and final inspection. ANSI B18.2.1 bolts are very important in every step of the process. Take the cold forging process. Under normal circumstances, the forming of the ANSI B18.2.1 bolt head is processed by cold heading plasticity. There are very few cases where it is processed by cutting. However, compared to the cutting of metal fibers, it is often said that the metal wire is continuously distributed along the shape of the product, without cutting between them, so the strength of the ANSI B18.2.1 bolt is improved, especially the mechanical mechanism of the ANSI B18.2.1 bolt. The performance is outstanding.

The cold heading forming process of ANSI B18.2.1 bolts also outlines the cutting process and forming, and is divided into single station click and double click cold head and multi-station automatic cold heading. Only one automatic cold heading machine can perform stamping and pierging, extrusion and reduction of multi-station processes in a plurality of forming concave molds. Sometimes a single station is used. Whether it is a multi-station or single-station automatic cold heading machine, the original blank is processed by a bar with a material size of five to six meters or a wire weight of one thousand nine hundred to two thousand kilograms. To make a decision. That is to say, the cold forging forming process of ANSI B18.2.1 bolts is characterized in that the cold heading is not a pre-cut single-sheath blank, but is obtained by cutting off the oil bar and the wire rod of the automatic cold heading machine. In some cases, the embryo should be used.

The above is the process that ANSI B18.2.1 bolts are formed during the forging process. It is not necessary that they are trained in such a complicated process, but we must ensure that each process is executed through strict specifications. Only in this way can we not think about it in the forging process, so that every process is strictly docked.
