Abstract
The present invention discloses a method for manufacturing a copper roll type of a commutator, which comprises the procedures of rolling wires, drawing, annealing, punching, pressing, solidifying, reaming, turning, milling groove, sanding, polishing, etc. in sequence, wherein in the punching procedure, annealed wires are punched into an annular commutating segment group. The method for manufacturing a copper roll type of a commutator has the advantages of saving the original complicated segment arranging procedure, relieving workers' labor strength, simplifying production procedures, improving work efficiency and reducing production cost. In addition, produced commutator finished products have the advantages of high circularity, reducing the dynamic unbalance quantity of a commutator and improving the service performance of a motor.
Description
One, technical field
The present invention relates to the manufacture method of a kind of motor with commutator.
Two, background technology
Prior motor is the screening formula with the manufacture method of 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 screening, compacting, curing, fraising, turning, groove milling, sanding, polishing process, and be made into the commutator finished product.It is Chinese invention patent application " slice arranging apparatus of commutator and screening technology thereof the " (application number: 93120155.1 of CN 1089762A that the principle of its screening operation has adopted publication number, open day: on July 20th, 1994, Granted publication day: May 31 nineteen ninety-five), promptly utilize cylinder core slice arranging apparatus to be skeleton, embed the commutator segment monolithic of commutator in the groove of slice arranging apparatus one by one by same direction, again mica sheet is inserted between each commutator segment, then with tightening up the thing banding.Its wire drawing operation is to become cross section to be the wire rod of " worker " font wire drawing, punching out becomes the longitudinal section to be the commutator segment monolithic of swallowtail-shaped structure then, adding moulding compound suppresses, solidifies, thereby cause the contact area of commutator segment and moulding compound less, be that adhesive force between commutator segment and the moulding compound is less, cause the commutator of making in motor runs up process, to be easy to generate film dancing, film flying phenomenon.And need go out the dovetail part during punching out, and cause the wire rod loss more, utilance is lower.If the manufacture method of hook commutator, then needing increases " hook inner surface outside the car " operation between " turning and groove milling " operation, increases " hook outside curved " operation between " sanding and polishing " operation; Wherein groove milling operation comprises mills between the commutator segment sheet groove and mills outer hook groove.
In the screening formula manufacture method of above-mentioned commutator, operations such as " becoming the commutator segment monolithic to carry out screening and insert mica sheet again through cylinder core slice arranging apparatus the wire rod punching out " is complicated, loaded down with trivial details, inefficiency, production cost height.Particularly screening operation needs through personnel's manual operations, and commutator segment and this slice arranging apparatus exist the gap, half-finished circular runout big (being generally 6-8 μ m) makes the circularity of commutator relatively poor, thereby has influenced the serviceability of motor when causing the turning operation.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide that a kind of production process is simple, the commutator production process of copper roll type that the commutator circularity of high efficiency, the contact area that can increase commutator segment and moulding compound and output is good.
Purpose of the present invention realizes by following technical solution: a kind of copper roll type manufacture method of commutator, comprise wire rod rolling, drawing, annealing successively, and punching out, compacting, curing, fraising, turning, groove milling, sanding, polishing process, described wire drawing operation is to become cross section to be the wire rod of " K " font the wire drawing of rolling; Described punching out operation is the commutator segment sheet group that the wire rod punching out of will anneal circularizes, and the longitudinal section of the commutator segment sheet group that this is annular is " K " font structure.
Guarantee the commutator thickness and the width of hook outward respectively by described wire drawing operation and punching out operation, described groove milling operation can be to mill groove between the commutator segment sheet, and increases " hook outside curved " operation between described " sanding and polishing " operation.
Described groove milling operation can also be to mill between the commutator segment sheet groove and mill the bonding wire groove.
After adopting the present invention, because the commutator segment sheet group that the punching out operation directly circularizes the wire rod punching out need not used mica sheet, thereby saved original loaded down with trivial details screening operation, alleviated working strength of workers, production process is simplified, improve operating efficiency, reduced production cost.The commutator segment sheet group that the longitudinal section is the annular of " K " font structure can increase the contact area of commutator segment and moulding compound, makes linking intensity between commutator segment and the moulding compound and reliability, adhesive force obtain bigger raising, has also saved wire rod simultaneously.And arrange between the sheet of commutator segment sheet group that should annular evenly, during the turning operation half-finished circular runout little, can be controlled in the 3 μ m, the commutator finished product circularity of output is good, has reduced the unbalancing value of commutator, has improved the serviceability of motor.

Five, embodiment
The copper roll type manufacture method of commutator of the present invention, comprise wire rod rolling, drawing, annealing successively, and punching out, compacting (adding moulding compound), curing, fraising, turning, groove milling, sanding, polishing process, described wire drawing operation is to become cross section to be the wire drawing of rolling: K " wire rod (as depicted in figs. 1 and 2) of font; Described punching out operation is the commutator segment sheet group that the wire rod punching out of will anneal circularizes, and the longitudinal section of the commutator segment sheet group that this is annular is " K " font structure, and (the punch press punching out by 10 tonnages forms, as shown in Figure 3 and Figure 4).Add moulding compound again and suppress, solidify, through fraising, turning, groove milling, sanding, polishing process and make the commutator finished product.As shown in Figure 5, the commutator of being made by the present invention comprises commutator segment and moulding compound 3, and wherein commutator segment comprises commutator segment body 1 and interior hook 2, described commutator segment body 1 and interior hook 2 be connected to form " K " font structure.
If the copper roll type manufacture method of hook commutator, then the thickness and the width of the outer hook of commutator are guaranteed by wire drawing operation and punching out operation respectively.Therefore, described groove milling operation is to mill groove between the commutator segment sheet, and increases " hook outside curved " operation between described " sanding and polishing " operation.Thereby saved and milled outer hook groove (i.e. the width of outer hook) program in outer hook inner surface (i.e. the thickness of outer hook) operation of car before the former groove milling operation and the former groove milling operation, reduced production cost.
If the copper roll type manufacture method of tank commutator, then described groove milling operation is to mill between the commutator segment sheet groove and mill the bonding wire groove.
