Manufacturing process of anti-rust metal stoving varnish

Abstract

The invention discloses a manufacturing process of anti-rust metal stoving varnish. The manufacturing process comprises the following steps that 1, a metal plate made of stainless steel is prepared, and a workpiece with a predetermined product shape is formed through punching, cutting and bending; 2, the surface of a product with the preset shape is subjected to dust removal and purification; 3, a first shielding jig is used for shielding a first area of the workpiece, a concave cavity is formed in the first area, and a through hole is formed in the wall face of the concave cavity; the rest part is sprayed with primer, and antirust pigment is added into the primer; 4, the first area of the workpiece is shielded through the first shielding jig, and the surface of the primer of the rest part is sprayed with finish paint; and 5, the first shielding jig is taken down, and the inner surface of the concave cavity of the first area is coated with conductive paint. The concave cavity and a hole site are formed in the metal plate, during paint baking, the part is shielded firstly, then the inner surface of the concave cavity is coated with the conductive paint, the manufacturing efficiency is effectively improved, and meanwhile the conductivity of the conductive position is reliable.

Description

technical field [0001] The invention relates to the technology in the field of metal plate production, in particular to a production process of an anti-rust metal baking paint. Background technique [0002] In the prior art, when the anti-rust baking paint is applied to the metal panel, usually the whole metal panel is formed with a baking paint layer, and some metal panels need to be partially equipped with a conductive position, and it is necessary to partially remove the paint on the part that has been painted and then weld it to conduct electricity. tabs or conductive terminals, etc., for subsequent wiring. This kind of production method has low validity. Moreover, it is generally done manually by first shoveling off the paint film with a spatula, and then using a copper wire brush to remove the remaining paint stains. Sometimes it is necessary to dip the paint thinner to wipe it off. , sometimes due to the difficulty in ensuring the quality consistency of manual operat...
