Embodiment 1

[0023] A production process of a novel electric brush, the production process sequentially includes:

[0024] Step 1: Select raw materials, which are silver powder, copper powder, ceramic powder, graphite powder, resin, and binder;

[0025] Step 2: Mix the silver powder, copper powder, ceramic powder, graphite powder, resin, and binder according to the weight ratio of 2:4:1:2:1:1, heat and stir, and the temperature is 50°C ;

[0026] Step 3: the above mixture is pulverized in a pulverizer, the granular mixture is screened, and the granular mixture is placed in a container for immersion, and the immersion time is 5.5 hours;

[0027] Step 4: put the impregnated granular mixture into a mold and press to obtain a semi-finished product;

[0028] Step 5: finishing and shaping the semi-finished product.

Abstract

The invention discloses a novel electric brush production technology. The production technology sequentially comprises the following steps of: I, selecting raw materials including silver powder, copper powder, ceramic powder, graphite powder, resin and binder; II, mixing the silver powder, copper powder, ceramic powder, graphite powder, resin and binder at a weight ratio of 2:4:1:2:1:1, and heating and stirring, wherein the temperature is 40-60 DEG C; III, grinding the mixture in a grinder, screening the granular mixture, and soaking the granular mixture in a container for 5-6 hours; IV, pressing the soaked granular mixture in a mould to obtain a semi-finished product; and V, performing finishing molding of the semi-finished product. The technology disclosed by the invention is simple, generates relatively little spark and realizes relatively long service life.

Description

technical field [0001] The invention relates to a production process, in particular to a production process of a novel 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, 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 ...
