High strength nuts are used as connecting accessories for products, usually made of metal processing, such as steel or alloy steel. They have strong strength, strong separation and strong connection performance, and are widely used in various fields of national economic construction. However, with the development of industry, the connection of some structural components needs to be ablative and corrosion resistant. As a general metal nut, it is difficult to meet the requirements of ablative resistance and corrosion resistance. Therefore, it is necessary to redesign and study a new machining material nut. Therefore, the development of high strength nuts is imperative.

The forging and stamping of high strength nuts is called forging. Forging is a method of machining parts of the desired shape and size by applying pressure to the blank through the punch or die of a forging machine to create a plastic deformation. It can not only obtain more accurate metal parts shape, save metal materials and cutting time, but also improve the internal structure of the metal, improve the mechanical and physical properties of the metal. Forging processing technology determines its high production efficiency and flexibility, and also makes it one of the most commonly used processing methods in machining

As one of the important parts of fasteners, high-strength nuts are widely used and consumed. The nut is the main product of the enterprise, and its core competitiveness lies in the quality and output of the product. However, at present, the nut forging production mostly adopts the multi-machine connection mode, and the transportation and feed between the workbench are completely completed by manual, which has low production efficiency and poor product quality. For workers, the production environment is harsh, the work space is full of oil and high temperature, there are great safety risks, easy to burn. With the increase in wages of workers in developing societies, such production conditions are poor and difficult to recruit for dangerous jobs. In view of the current production situation, nut production enterprises urgently need to automate the existing forging production line to replace the original manual operation, reduce the workload, reduce the labor intensity of workers, improve the production environment, and improve product quality. And productivity.
