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
One, technical field
The present invention relates to the manufacture method of the end commutator that a kind of motor uses.
Two, background technology
Prior motor is a blade inserting with the manufacture method of end commutator, promptly at first wire rod is carried out rolling, drawing, annealing, then this wire rod punching out is become commutator segment monolithic (punch press by 5 tonnages carries out punching out), again through operations such as inserted sheet, injection mo(u)lding, turning and end face, groove milling, polishings, and make the end commutator finished product.Wherein the inserted sheet operation is to utilize by hand the commutator segment monolithic is embedded one by one by same direction in the groove of special slice arranging apparatus, mica sheet is inserted between each commutator segment, then with tightening up the thing banding again.If the manufacture method of grooved end commutator, then groove milling operation comprises branch groove and bonding wire grooves such as milling commutator segment.If the manufacture method of hook end commutator, then needing increases " hook inner surface outside the car " operation again between " turning and end face and groove milling " operation, increase " hook moulding outside curved " operation between " groove milling and polishing " operation again; Wherein groove milling operation comprises branch grooves such as milling commutator segment and mills outer hook.
In the blade inserting manufacture method of above-mentioned end commutator, " wire rod is carried out rolling, drawing, annealing; and become the commutator segment monolithic to carry out screening and insert mica sheet again this wire rod punching out through slice arranging apparatus " etc. operation complicated, loaded down with trivial details, production efficiency is low, the cost height.Particularly the inserted sheet operation needs through personnel's manual operations, make commutator segment and this slice arranging apparatus exist the gap, the half-finished circular runout of end commutator is bigger when causing turning and end face operation, makes the circularity of commutator relatively poor, thereby influenced the serviceability of motor.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and the manufacture method of the simple and end commutator that commutator circularity output is good of a kind of production efficiency height, manufacture method is provided.
Purpose of the present invention realizes by following technical solution: a kind of manufacture method of end commutator, at first used silver-bearing copper bar is cut into cylindrical copper sheet, then this cylindrical copper sheet is formed bowl formula commutator segment sheet group through cold extrusion shaped operation, and through scraping end flat, boring endoporus, and piercing inner-hook two places and disposal molding, again through injection mo(u)lding, turning and end face, groove milling, polishing process and make the end commutator finished product.
Described groove milling operation can be for milling branch groove and bonding wire grooves such as commutator segment.
Described groove milling operation can also be for milling branch groove such as commutator segment and mill outer hook, and increase " hook circle car in " operation again between " turning and end face and groove milling " operation, increase again " hook moulding outside bending " operation between " groove milling and polishing " operation.
After adopting the present invention, because cold extrusion shaped operation is directly made cylindrical copper sheet a bowl formula commutator segment sheet group, need not use mica sheet, thereby saved original loaded down with trivial details inserted sheet operation, alleviated working strength of workers, manufacturing procedure is simplified, and has improved production efficiency, has reduced production cost.And arrange between the sheet of this bowl formula commutator segment sheet group evenly, when carrying out turning and end face operation half-finished circular runout little, make the end commutator finished product circularity of output good, improved its serviceability in motor.

Five, embodiment
The manufacture method of end commutator of the present invention is: at first used silver-bearing copper bar (as shown in Figure 1) is cut into cylindrical copper sheet (as Fig. 2 through sawing machine, shown in Figure 3), then this cylindrical copper sheet is used 100T hydraulic press (adopting the cold extrusion particular manufacturing craft), form bowl formula commutator segment sheet group (as Fig. 4 through cold extrusion shaped operation, shown in Figure 5), and scrape its end flat (making the commutator segment uniform thickness) through instrument lathe (employing special fixture), bore endoporus, and use punch press piercing inner-hook two places and disposal molding (as Fig. 6, shown in Figure 7), add moulding compound through the 100T hydraulic press again and carry out the injection moulding hot briquetting, moulding is after the turning of instrument lathe and end face, groove milling through slotter, through the polishing operations such as (deburrings) of grinder and make the end commutator finished product.
If the manufacture method of grooved end commutator, then described groove milling operation is for milling branch groove and bonding wire grooves such as commutator segment.If the manufacture method of hook end commutator, then described groove milling operation is for milling branch groove such as commutator segment and milling outer hook, and between " turning and end face and groove milling " operation, increase " hook circle in the car " (instrumentation lathe) operation again, between " groove milling and polishing " operation, increase " hook moulding outside curved " (use punch press) operation again.
In order to increase the contact area of commutator segment and moulding compound, the mechanical strength of end commutator is improved, in described piercing inner-hook two places and disposal molding operation, the interior hook punching out of commutator segment can be become " eight " font structure (as shown in Figure 6).
Claims (4)
