Processing technique for compressor shell

Abstract

The invention relates to a processing method of a workpiece, in particular to a processing technique for a compressor shell. The processing technique for the compressor shell is characterized by comprising the following steps: 1, blanking, namely blanking after determining the new blanking size of the compressor shell in a novel technical process; 2 stretching, namely punching the blanked blank material on a blanking die to form a stretched blank piece needed by a stretched compressor shell, wherein it is required to make sure that the stretching length is at least 3 to 4 millimeters greater than the maximum depth of the part; and 3, trimming, namely trimming the stretched blank piece and obtaining the part. In conclusion, in the compressor shell produced by using the processing method and corresponding mold or equipment of the method, the material increasing the thickness of a stretched flange is transformed into the material required by the part and an overlapped edge; and thus, the material consumption in the production of the compressor shell is reduced by 0.046 to 0.07kg, the cost per product is reduced by 0.176 to 0.267 Yuan, and the production steps of the product are reduced.

Description

technical field [0001] The invention relates to a processing method of a workpiece, in particular to a processing technology of a compressor shell. Background technique [0002] The processing of the existing compressor casing needs to be completed through five steps of blanking, stretching, edge trimming, straightening, and repairing. In such a process flow, since the edge of the binder is relatively thick during stretching (that is, the thickness of the edge is greater than the thickness of the workpiece), the thicker edge part is cut off as waste when cutting the edge, so that the cut waste part will be Waste is not conducive to energy saving and consumption reduction; and affected by the anisotropy of the material, the flatness of the mouth of the compressor shell after trimming and straightening cannot be guaranteed, and a repair process is required to ensure it, which also increases the cost of the product. The production cost hinders the development of the enterprise...
