Problems solved by technology

The mixed strong adhesive used in this bonding method is a dry agent, which cannot be sprayed with a welding torch. Manual operation is required to cause uneven application and low work efficiency; the temperature required for bonding is low, and the commutator plate body is combined with the carbon block It is not strong, and it is difficult to withstand the high-speed operation of the motor, which affects the mechanical and conductive technical performance of the carbon commutator

Embodiment Construction

[0007] The present invention will be further described in detail below in combination with embodiments.

[0008] The welding process of the carbon commutator of the present invention is: the outer surface (using welding torch) of the commutator segment body of the punched commutator segment group (for the ring) is coated with alloy welding agent (that is, on the outer surface of the commutator segment body) Form a welding coating on the surface), then insert the carbon block on the alloy solder, and then transport the commutator segment group with the carbon block (through the conveyor belt) to the special welding equipment (it can be a brazing machine) , under the action of a high temperature above 900 degrees Celsius, it takes more than 30 minutes to weld it into a carbon commutator blank. Thereafter, the finished carbon commutator is made by pressing, curing, reaming, turning the outer circle, milling groove, sanding, polishing and other processes. This welding process is ...

Abstract

The invention relates to a welding method of carbon steering device. Wherein, it plates alloy welding agent on the outer surface of main body of steering plate which is punched; then embeds the carbon block on the alloy welding agent; and transmits said steering plate to special welding device, at 900Deg. C, to be welded for 30mins into carbon steering device blank. The invention has firm connection between main body and carbon block, to improve the working efficiency and improve the mechanical property of carbon steering device.

Description

1. Technical field [0001] The invention relates to a carbon commutator for a motor, in particular to a process for combining a commutator segment (body) and a carbon block of the carbon commutator. 2. Background technology [0002] Chinese invention patent specification CN 1234198C (authorized announcement date: December 28, 2005, patent number 03107188.0) discloses a planar carbon commutator, including commutator segments, molding compounds, carbon blocks, and the body of the commutator segment and the The axis of rotation of the commutator is vertical, and the commutator piece is arranged in the molding compound and exposes the outer surface of the body of the commutator piece, and is plated with a silver-copper alloy layer on the outer surface of the body of the commutator piece. The silver-copper alloy layer is coated with a mixed strong adhesive layer, and the carbon block is arranged on the mixed strong adhesive layer. [0003] The planar carbon commutator combines th...
