Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with specific embodiments

[0012] A production process of a wear-resistant electric brush, the production process sequentially includes:

[0013] Step 1: Select raw materials, namely chromium, phosphorus powder, graphite powder, resin, alcohol, and lubricating material;

[0014] Step 2: mixing the chromium, phosphorus powder, graphite powder, resin, alcohol, and lubricating materials in a weight ratio of 4:1:2:2:1:1;

[0015] Step 3: the above mixture is placed in a pulverizer and pulverized into granules, the particles are screened, and the powder is removed, again placed in a pulverizer and pulverized into powder, placed in a mold and pressed into a finished product, the semi-finished product is subjected to chemical treatment, and the An oxide film is formed on the surface;

[0016] Step 4: Detect, screen qualified products, and finish molding.

[0017] To sum up, the process of the pres...

Abstract

The invention discloses a production process for an abrasion-resistant electric brush. The production process comprises a first step of selecting raw materials which are respectively chromium, phosphorus powder, graphite powder, resin, alcohol and a lubricating material; a second step of mixing chromium, the phosphorus powder, the graphite powder, the resin, the alcohol and the lubricating material at a weight ratio of 4:1:2:2:1:1; a third step of placing the mixture in a pulverizer to smash the mixture into particles, screening the particles, removing the powder, placing the particles in the pulverizer again to smash the particles into powder, and placing the powder in a die to make finished products by pressing, enabling the semi-finished products to undergo chemical treatment, and forming a layer of oxide film on the surface; a fourth step of performing detection to screen qualified products, and performing finishing forming. Therefore, the electric brush is simple in process, easy to operate and good in abrasion resistance.

Description

technical field [0001] The invention relates to a production process of an electric brush, in particular to a production process of a wear-resistant electric brush. Background technique [0002] A brush is a conductive component that makes sliding contact with a moving part to form an electrical connection. The brush is used on the commutator or slip ring as a sliding contact body for importing and exporting current. It has good electrical conductivity, thermal conductivity and lubricating properties, and has certain mechanical strength and reversible spark instinct. Almost all DC motors and commutation motors use brushes, which are an important component of the motor. Brushes are more and more widely used in daily life. Many household appliances need to use brushes, such as vacuum cleaners, household Crusher etc. However, common brushes have the disadvantages of short service life, non-wear resistance, and large sparks. Contents of the invention [0003] The technical...
