Production process of sheet metal part and dust removal system of sheet metal part

Abstract

The invention discloses a production process of a sheet metal part and a dust removal system of the sheet metal part. The production process of the sheet metal part and the dust removal system of thesheet metal part are realized by punching, bending, welding, grinding, dust removal, spraying and drying and other processes. The dust removal system comprises a conveying chain and a box body, a hanging piece for connecting with the sheet metal part in a hang mode is arranged on the conveying chain, and the conveying chain passes through the box body. The box body is internally provided with a partition and separated into a spray chamber and a blowing chamber, and spray heads for spraying water are arranged on the inner wall of the spray chamber. Air blowing ports for blowing hot air are formed in the inner wall of the blowing chamber, and the air blowing ports are separately arranged on different sides of the corresponding sheet metal part. The hanging part is rotatably connected to theconveying chain, an air suction port is formed in the bottom of the blowing chamber, and a fan is arranged in the air suction port. A rotating shaft of the fan extends into the blowing chamber and a fixed strip is fixed to the rotating shaft, and a strip groove for the bottom end of the sheet metal part passing through is arranged on the fixed strip. First of all, the spray of the spray chamber achieves the purpose of surface cleaning, then the sheet metal part is blown and rotated by the air blowing ports in the blowing chamber, so that the dust removal of sheet metal part is more comprehensive and thorough.

Description

technical field [0001] The invention relates to the field of sheet metal parts production, more specifically, it relates to a sheet metal part production process and a dust removal system thereof. Background technique [0002] Sheet metal parts are relatively common hardware accessories. For example, electrical cabinets and cabinet doors are sheet metal parts. The surface of sheet metal parts needs to be sprayed in the later stage of production. Spraying refers to coating the surface of sheet metal parts with corresponding Paint to improve the performance of sheet metal parts. After the sheet metal parts are polished, a lot of powder or dust is often adhered to the surface. These powders and dust will generate a large number of dust spots on the sheet metal parts during subsequent spraying operations, which will affect the spraying process. Effect. [0003] It is also possible to remove dust on the surface of sheet metal parts by setting a blowing room before spraying. Basi...
