Problems solved by technology

Among them, the pressing process is to remove the core and fasteners from the commutator plate group after the film is arranged, and then put the copper bar of the commutator plate into the feeding seat, and then manually send it into the pressing device and the pressing mold, and add the molding compound (or called Bakelite powder) for pressing treatment, and then manually carry out waste removal, commutator pressing products and other processing, which is a semi-automatic process with low production efficiency and low safety performance. Generally, one operator can only be responsible for one pressing Machine production, work efficiency is also low

Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0012] A kind of commutator processing technology, its step comprises:

[0013] (1) Arrange the stamped commutator pieces and mica pieces into a cylindrical shape, put on the shaping mold, press them into the pressure film, and put in the weighed plastic;

[0014] (2) Close the mold and press it on a hot press. The feeding cylinder sends the feeding seat with the commutator piece to the waiting area of ​​the middle mold, and sends the commutator piece to the middle mold; the middle mold cylinder puts the The middle mold is sent to the station, and the upper mold, middle mold and lower mold are pre-closed, and then the cake is put into the upper mold to completely close the pressing mold and keep the pressure; after the pressure is maintained, ...

Abstract

The invention provides a commutator processing technology. Since an intermediate mold cylinder, a lower mold cylinder, a feeding cylinder and a pushing cylinder are arranged to correspondingly adjust and control the pushing of an intermediate mold, a lower mold, a feeding seat and a commutator pressed product respectively, feeding of a commutator bar, pushing of the commutator pressed product and pushing processing of a pressed mold can be automatically operated, and thus the working efficiency and the production safety can be improved; an operator can simultaneously adjust and control multiple technological flows and multiple machines, and thus the production cost of the commutator is reduced.

Description

[0001] technical field [0002] The invention relates to the field of commutator manufacturing, in particular to a commutator processing technology. Background technique [0003] The commutator is a part of the DC permanent magnet series motor in order to allow the motor to continue to rotate. Commutators include: mechanical commutators, semi-plastic commutators, and all-plastic commutators. The commutators used in automobile starters mainly use mechanical arch commutators and plastic commutators. Structurally, the commutator is a circle surrounded by several contact pieces, which are respectively connected to each contact on the rotor. The two electrodes connected to the outside are called brushes, and only two of them are in contact at the same time. At present, the known commutator manufacturing processes include extrusion, drawing, punching, lamination, pressing, curing, inner hole, outer circle, sanding, polishing and so on. Among them, the pressing process is to rem...
