Embodiment 1

[0022] A method for making an electric brush, comprising the following steps:

[0023] Step 1: Select raw materials, namely copper disulfide, graphite powder, resin, alcohol, binder, lubricant;

[0024] Step 2: Mix copper disulfide, graphite powder, resin, alcohol, binder, and lubricant in a mixer in a weight ratio of 1:5:3:2:1:1;

[0025] Step 3: Put the above-mentioned mixture in a pulverizer and pulverize it into powder, screen out the fine powder, then roast in a boiler to make a semi-finished product, and the temperature is 250°C;

[0026] Step 4: Graphitize the semi-finished product and test the qualified product;

[0027] Step 5: Mechanical processing to obtain the finished product.

Abstract

The invention discloses a manufacturing method for an electric brush. The manufacturing method for the electric brush comprises the following steps of: one, selecting raw materials such as copper disulfide, graphite powder, resin, alcohol, a bonding agent and a lubricant respectively; two, mixing the copper disulfide, the graphite powder, the resin, the alcohol, the bonding agent and the lubricant in a stirring machine according to the weight ratio of 1:5:3:2:1:1; three, crushing a mixture into powder in a crushing machine, screening out fine powder, and roasting the fine powder in a boiler to prepare semi-finished products, wherein the temperature is between 200 and 300 DEG C; four, performing graphitization processing on the semi-finished products and detecting qualified products; and five, machining to obtain finished products. Therefore, the manufacturing method for the electric brush is simple, easy to operate and high in electronic interference resistance.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method of a 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, household water dispenser, etc. However, common brushes have the disadvantages of short service life, non-wear resistance, and large sparks. Contents of the invention [0003] The technical problem to b...
