Forming die and method for static plates of double-side scroll plates of air conditioner compressor

Abstract

The invention discloses a forming die and method for static plates of double-side scroll plates of an air conditioner compressor, and belongs to the technical field of metal plastic forming. The forming die comprises a finish forging die and a preforming blank die. Compared with a traditional three-step forming method, the two-procedure forming method of pre-forging blank making and forward and reverse combined extrusion finish forging is adopted, the procedures are greatly simplified, and the production efficiency is greatly improved; compared with a traditional one-step forming method, the forming tonnage is remarkably reduced through pre-forging, and the defect that the service life of the die is shortened due to stress concentration is overcome; during finish forging forming, a back pressure forming technology is adopted on the lower portion, a back pressure assembly provides back pressure through an elastic body, the metal flow speed of a scroll part on the lower portion can be effectively controlled, and the height and flatness of the scroll part can be effectively controlled after forming is completed; and during finish forging forming, a backward extrusion technology is adopted on the upper portion, and due to the existence of the back pressure assembly on the lower portion, the forming tonnage can be remarkably reduced during shaping.

Description

technical field [0001] The invention relates to the technical field of metal plastic forming, in particular to a forming mold and method for a double-side scroll disk static disk of an air-conditioning compressor. Background technique [0002] With the continuous improvement of people's living standards, more and more cars have entered ordinary people's homes. As one of the main components of cars, car air conditioners are related to the use of cars. The core component of the air-conditioning unit is the refrigeration compressor, and the scroll compressor is widely used because of its compact structure, light weight, slight vibration, low noise and long life. The scroll is a key part of the compressor, and its forming quality directly affects the working state of the air conditioner. [0003] The traditional scroll disk static disk only has a scroll part on one side, and the movable disk and static disk are placed in the compressor shell after they cooperate with each other...
