Abstract

The invention discloses a production process of a range hood, and relates to the technical field of range hood processing. The production process comprises the following process steps: S1, cutting a stainless steel raw material to obtain a raw material combination board; S2, bending and stamping the raw material composition board, and obtaining a finished product composition board; S3, combining and welding the finished product composition board to form a primary weld joint, obtaining a semi-finished range hood shell and before welding, pretreating the welding surface of the composition board;S4, polishing a primary weld joint on the semi-finished range hood shell; S5, observing the polished weld joint, treating defective welding points on the polished weld joint by using a surface treating agent, and then carrying out repair welding to obtain a finished product of the range hood shell; and S6, carrying out complete machine assembly on the finished range hood shell, and obtaining therange hood; and S7, carrying out an aging test on the range hood, and packaging after the test is qualified. The preparation method has the advantage that the mechanical property and the mechanical strength of the shell of the range hood are improved.

Description

technical field [0001] The invention relates to the technical field of range hood processing, in particular to a production process of the range hood. Background technique [0002] In the production process of the range hood, the range hood casing is first produced, and then the range hood casing and the fan and other electronic components are assembled as a whole to obtain the finished range hood. [0003] In the production process of the existing range hood casing, the raw material steel plates are cut, the cut steel plates are combined and assembled, and then welded at the joints, the weld seam produced by the initial welding is polished, and the weld seam is repaired. Perform technological steps such as repair welding to obtain a complete range hood casing. [0004] The above-mentioned existing technical solutions have the following defects: when the shell of the existing range hood is assembled and welded, because the raw material of the range hood is stainless steel p...
