Method for manufacturing mounting box of line control panel

Abstract

The invention relates to a method for manufacturing a mounting box of a line control panel. The method includes steps of providing a galvanized plate; manufacturing the galvanized plate into a plurality of regular rectangular blocks by a plate shearing machine according to preset rules; curling edges of a first rectangular block and punching the first rectangular block to form an upper cover comprising a cover top and a cover edge integrally formed with the cover top; stretching a second rectangular block of the multiple rectangular blocks to form a bottom plate; bending a third rectangular block so that one end of the third rectangular block is connected with the other end of the third rectangular block and is snapped with the other end of the third rectangular block in a bent and hooked manner to form a hollow rectangular box body; and stamping and stretching a fourth rectangular block to form a support. The cover edge is fastened on the box body in a tightly combined mode, the edge of the box body is overlapped with the edge of the bottom plate and is fixedly curled from the outer portion of the box body to the inner portion of the box body, and the box body and the bottom plate form an accommodating cavity for accommodating the line control panel. One end of the support extends along the box body to reach the bottom plate and is fixed onto the bottom plate, and the other end of the support outwardly extends in the direction perpendicular to the box body.

Description

technical field [0001] The invention relates to a method for manufacturing an installation box, in particular to a method for manufacturing a circuit control board installation box. Background technique [0002] At present, household appliances, especially cabinet-type air conditioners, generally use galvanized sheet stamping and bending to make the circuit control panel installation box. The circuit control panel installation box has a large thickness, which is not conducive to the miniaturization and low-cost cost requirements. In addition, the circuit control board installation box also needs to be welded, so the manufacturing process is relatively cumbersome. Contents of the invention [0003] In view of this, it is necessary to provide a method for manufacturing a circuit control board installation box, which aims at making a circuit control board installation box with a better thickness. [0004] The present invention is achieved in this way, a method for manufactu...
