Problems solved by technology

[0003] In the insert-type manufacturing method of the above-mentioned end-face commutator, "rolling, drawing, and annealing the wire rod, and punching the wire rod into a single piece of commutation piece through the piece arrangement device to arrange the piece and then insert the mica piece" The process is more complex and cumbersome, the production efficiency is low, and the cost is high
In particular, the insertion process needs to be manually operated by personnel, so that there is a gap between the commutator segment and the disc arrangement device, resulting in a large radial runout of the semi-finished end face commutator during the outer circle of the car and the end face process, making the roundness of the commutator Poor, which affects the performance of the motor

Embodiment Construction

[0017] The manufacturing method of the end face commutator of the present invention is as follows: first, the used silver-copper rod (as shown in Figure 1) is cut into cylindrical copper sheets (as shown in Figures 2 and 3) by a sawing machine, and then The cylindrical copper sheet uses a 100T hydraulic press (using a special cold extrusion mold), and forms a bowl-type reversing sheet group (as shown in Figure 4 and Figure 5) through the cold extrusion molding process, and is passed on an instrument lathe (using a special fixture) Scrape the two ends of the plane (make the commutator pieces the same thickness), drill the inner hole, and use a punching machine to punch out the inner hook of the inner bottom of each commutator piece of the commutator piece group (as shown in Figure 7) Numbers A and B are shown in two places) and it is a one-time molding (as shown in Figure 6 and Figure 7), and then added molding compound by a 100T hydraulic press for injection molding and heating mo...

Abstract

The present invention discloses a method for making end face commutator. Said method includes the following steps: cutting silver copper rod material into cylindrical copper plate, then making said cylindrical copper plate form segment group through cold extrusion formation, scraping two end plane surfaces, drilling internal hole, stamping inner hooks, injection moulding, turning excircle and end face, grooving and polishing so as to obtain the end face commutator finished product.

Description

1. Technical Field [0001] The invention relates to a method for manufacturing an end face commutator for a motor. 2. Background technology [0002] The existing manufacturing method of the end face commutator for the motor is the insert type, that is, the wire is first rolled, drawn, and annealed, and then the wire is punched into a single piece of the commutator (punched by a 5-ton punch After the process of inserting, injection molding, car outer circle and end face, milling groove, polishing, etc., the end face commutator is made into a finished product. Among them, the inserting process is to manually insert the commutator pieces into the grooves of the special arrangement device one by one in the same direction, then insert the mica pieces between the commutator pieces, and then tighten them with fasteners. If it is the manufacturing method of the slot-type end face commutator, the slot milling process includes milling the commutator segment and the welding slot. If it is a ...
