Abstract
This invention discloses a manufacturing method for a commutator including: rolling wires, pulling, punching, arranging chips, pressing, curing, reaming, lathing the excircle, channeling and polishing, among which, said pulling process is that a rolled wire is drawn to an 'I' shaped wire with two symmetric ends, said punching process is to punch the drawn wire to a commutating single chip with a central line symmetric arched bridge at the foot. When pulling, the ladder arrangement is forced uniformly and the punch die is forced smoothly when punching, which can use the wire bilaterally to punch a pair of commutating plates at the same time.
Description
One, technical field
The present invention relates to manufacture method of the commutator that a kind of motor uses and products thereof.
Two, background technology
Prior motor with the manufacture method of commutator is: at first wire rod is carried out rolling, drawing, annealing, the wire rod punching out that to anneal then becomes the commutator segment monolithic, again through operations such as screening, compacting, curing, fraising, turning, groove milling, polishings, and make the commutator finished product.Wherein drawing and punching out operation are that the wire rod after the rolling (claiming ladder row again) is drawn into the wire rod (two ends that are wire rod are asymmetric: one is long and the other is short) that is " worker " font, and punching out becomes foot to be the commutator segment monolithic of swallowtail-shaped structure then.Ladder row discontinuity during drawing, the drawing difficulty increases, and size is difficult for guaranteeing; And the wire rod after the drawing is in the punching out process, and asymmetric because of the wire rod two ends, an end cutting output is more, and an end cutting output is less, makes the punch die unbalance stress, has reduced the useful life of punch die.Must can only arrange by unidirectional use ladder towards the part material except that dovetail owing to requiring to go out swallowtail shape when punching out, stock utilization is low, causes waste of material.By the commutator that this manufacture method is made, the foot of its commutator segment is a swallowtail-shaped structure, and is less with the contact area of moulding compound, and promptly the adhesive force between commutator segment and the phenolic moulding powder is less.This commutator is easy to generate film dancing, film flying phenomenon in motor runs up process, and the grade of spark that causes motor to produce increases, even burns motor.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide a kind of ladder row's drawing easy, stressed evenly, and the manufacture method of the commutator that stock utilization is high during punching out and products thereof.
Purpose of the present invention realizes by following technical solution: a kind of manufacture method of commutator, comprise wire rod rolling, drawing successively, and punching out, screening, compacting, curing, fraising, turning, groove milling, polishing process, described drawing procedure is the wire rod that is " I " font that the wire drawing after the rolling is become the two ends symmetry; Described punching out operation is to become foot to be the commutator segment monolithic of the arch-shaped structure of center line symmetry the wire rod punching out after this drawing.
As the commutator that above-mentioned manufacture method is made, comprise commutator segment, moulding compound, the foot of described commutator segment has the arch-shaped structure that is the center line symmetry.
After adopting the present invention, owing to be the wire rod two ends symmetry of " I " font, make ladder row stressed even during drawing, drawing is easy, and size is easy to control; When this wire rod entered the punch die punching out, because wire rod two ends symmetry, cutting output was identical, made punch die stressed mild, had prolonged the useful life of punch die; The wire rod punching out that will be " I " font becomes foot to be the commutator segment monolithic of the arch-shaped structure of center line symmetry, can two-wayly utilize wire rod to go out a pair of commutator segment monolithic simultaneously just, and stock utilization is improved, and has reduced production cost.The commutator that this manufacture method is made, the foot of its commutator segment has the arch-shaped structure that is the center line symmetry, increased the contact area of commutator segment and moulding compound, make that contact strength is reliable between the two, adhesive force is improved, thereby effectively eliminated film dancing, the film flying phenomenon of commutator, prolonged the useful life of commutator, be specially adapted to pot motor.

Five, embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 as can be known, known wire rod two ends after rolling, drawing asymmetric (one is long and the other is short), it is analysed and observe and is " worker " font, and punching out becomes foot to be the commutator segment monolithic of swallowtail-shaped structure then.Must can only arrange by unidirectional use ladder towards the part material except that dovetail owing to requiring to go out the foot that is swallowtail shape when punching out, stock utilization is low.
The manufacture method of commutator of the present invention, comprise wire rod rolling, drawing (having contained annealing) successively, and punching out, screening, compacting, curing, fraising, turning, groove milling, polishing process, described drawing procedure is the wire rod that is " I " font (as Fig. 4, shown in Figure 5) that the wire drawing after the rolling is become the two ends symmetry; Described punching out operation is to become foot to be the commutator segment monolithic of the arch-shaped structure of center line symmetry the wire rod punching out after this drawing, and promptly the foot of commutator segment has that center line vertical with it, level is about axle, equal arch-shaped structure of symmetry up and down.Ladder during punching out is arranged floor plan as shown in Figure 6, and punching out just can two-wayly utilize wire rod to go out a pair of commutator segment monolithic simultaneously like this, and stock utilization is improved.Commutator segment monolithic after the punching out as shown in Figure 7.
With reference to Fig. 8 as can be known, the commutator of making as above-mentioned manufacture method, comprise commutator segment 1, moulding compound 2, the foot 3 of described commutator segment 1 has the arch-shaped structure that is the center line symmetry, and promptly the foot of commutator segment has that center line vertical with it, level is about axle, equal arch-shaped structure of symmetry up and down.The foot structure of this commutator segment is equally applicable to hook or tank commutator.This commutator is specially adapted to pot motor.
Claims (2)
1, a kind of manufacture method of commutator, comprise wire rod rolling, drawing successively, and punching out, screening, compacting, curing, fraising, turning, groove milling, polishing process, it is characterized in that: described drawing procedure is the wire rod that is " I " font that the wire drawing after the rolling is become the two ends symmetry; Described punching out operation is to become foot to be the commutator segment monolithic of the arch-shaped structure of center line symmetry the wire rod punching out after this drawing.
