Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a compressor casing stamping device. Background Art

[0002] The refrigerator compressor is the core component of the refrigerator refrigeration system. Its main working principle is to inhale low-temperature and low-pressure refrigerant gas from the intake pipe, compress it by driving the piston through the operation of the motor, and then discharge high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle.

[0003] Refrigerator compressor housings are usually produced and processed by stamping technology. During the stamping process, hot stamping is usually used to ensure that the shape and size of the stamped compressor housing meet the design requirements. However, during the hot stamping process, metal sheets are subjected to stamping force, and metal slag will inevitably fall off. Moreover, the metal slag will adhere to the wall of the mold cavity under the condition of extrusion force. It is difficult to effectively remove it only by air guns, vacuum cleaners, etc., and manual cleaning is time-consuming and labor-intensive. In view of this, the present application proposes a compressor housing stamping device. Utility Model Content
