Problems solved by technology

[0003] However, when using a stirring motor at present, due to the large starting torque and frequent starting of the mixer, a large current passes through the brush every time it is started, so that when the motor starts, the commutation spark of the brush will be large, and the electrical wear of the brush will be serious. In order to meet the service life, resin-based brushes with low friction coefficient are generally used, and this type of resin also includes elements such as sulfur and nitrogen, and in the process of processing, it is only processed by ordinary mixing, pressing molding, curing and sintering Brushes of various specifications, so that when there is friction between the brushes and the commutator, the sulfur and nitrogen contained in the brushes will oxidize to generate gas. At the same time, the mixer is generally used in a relatively closed space, so after frequent use It will emit an unpleasant smell, which will affect the experience of use

Abstract

The invention discloses a manufacturing process of a brush of a mixer. The manufacturing process comprises that 20-30 parts of thermosetting resin by mass are added to an organic solvent and stirred uniformly to obtain a first mixture; 70-80 parts graphite by mass are added to the first mixture and stirred uniformly to obtain a second mixture; the second mixture is dried till the mass of the second mixture is constant; the second mixture of constant mass is crushed, and compacted and molded to obtain a third mixture; the temperature of the third mixture rises to 80-100 DEG C, and 7-8 parts hydrogen peroxide by mass is added, and the temperature is kept for 20-25 minutes; 2-3 parts of calcium chloride powder and 6-7 parts of a dense hydrochloric acid solution by mass are added to the thirdmixture, the temperature is kept for 30-35 minutes, and a fourth mixture is obtained; and the fourth mixture is sintered at high temperature, and processing is completed. According to the manufacturing technology of the brush of the mixer, a good using experience is obtained by stabilizing nitrogen elements and removing thionin.

Description

Technical field [0001] The invention relates to the technical field of production of mixers, in particular to a manufacturing process of an electric mixer brush. Background technique [0002] With the improvement of people's living standards, household mixing motors (such as soymilk machines, juice machines, juice machines, etc.) are used more and more, and the market is expanding rapidly. Most of these motors are AC series motors, which require brush parts. [0003] At present, when using a stirring motor, due to the large starting torque and frequent starting of the mixer, a large current flows through the brush each time it starts, so when the motor starts, the brush commutation sparks will be large, and the electrical wear of the brush is serious. In order to meet the longevity, resin-based brushes with low friction coefficient are generally used, and this type of resin also contains elements such as sulfur and nitrogen, and in the process of processing, it is only through ord...
