European link double-ring buckle body forge piece forming process

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...
