Embodiment Construction

[0024] European link double ring buckle forgings such as figure 2 shown. The basic shape of the forging is U-shaped, and one end of the U-shaped is split in the middle to form a fork. On the whole, the volume distribution of forgings is large at both ends and small in the middle section, and the distribution is asymmetric.

[0025] According to the characteristics of forgings, the focus of the forging process is the billet making process. The main function of the billet making process is to distribute the volume of raw materials reasonably, so as to reduce material waste and improve material utilization; reduce the forming force of subsequent processes and reduce the main equipment Kinetic energy consumption, saving energy. When selecting the billet making process, it is necessary to take into account the stability, operability, process automation and matching of the entire production line. In summary, the proposed process plan is cross wedge rolling, bending, die forging...

Abstract

The invention discloses a European link double-ring buckle body forge piece forming process. The process includes the following steps that 1, feeding is conducted, rod materials are cut into segmented blanks I; 2, heating is conducted, the blanks are heated; 3, the weight conservation principle is followed, a cross wedge rolling machine is adopted to make blanks, and the rolled blanks II are thick in the two ends and thin in the middles; 4, a bending die is adopted to bend the blanks II into blanks III, the bending degree of the blanks III is equal to that of a final forming forge piece of a buckle body; 5, primary forging is conducted on the blanks III in a primary forging die; 6, finish forging is conducted; 7, edge cutting is conducted; 8, reshaping is conducted. According to the process, the blanks are made through the cross wedge rolling machine, the blanks II are thick in the two ends and thin in the middles, and reasonable weight or size distribution is conducted on raw materials, so that waste of materials is reduced, that is, generated burrs are reduced, the material utilization rate is increased, meanwhile, in the forging process, the forging forming pressure is required, the kinetic energy consumption of a main machine is lowered, and energy is saved.

Description

technical field [0001] The invention relates to a European-style link double-ring buckle, in particular to a forming process for a body forging of a European-style link double-ring buckle. Background technique [0002] The European-style double-link buckle is a kind of lifting sling, including two buckle bodies and a pin connecting the two buckle bodies. At present, the European-style link double-ring buckle body forming process uses equal-diameter blanks for direct forging. This forging method is unreasonable, resulting in a large amount of material waste, low material utilization, high forging forming force, and high kinetic energy consumption of forging equipment. The cost of linking the double ring buckle body is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a European-style link double-ring buckle body forging forming process, which improves material utilization and reduces production costs...
