Abstract
Utilizing low cost pneumatic power or electric power source from plants or mines, the electrical machinery winding and the commutator are combined into an integrated one by stamp head. The advantages are: simple technology, easy to operation, secure connecting point, stable produce quality and suitable for various DC electrical machinery.
Description
The invention belongs to the coupling method of direct current machine winding and commutator, specifically is the stamping connecting method of a kind of direct current machine winding and commutator.
Now the domestic electric machine industry the winding of direct current machine be mostly the employing soldering connecting of commutator, several modes such as soldering and electric resistance welding, the operation principle of these several connections is when adding thermal head, to winding and commutator apply certain pressure or to both carry out heat more in addition scolder both are combined as a whole, the advantage of these several connecting modes is that production efficiency is higher, but all inevitably existed energy consumption big, the production cost height, narrow application range, unstable product quality, and these several connections all are at high temperature to carry out, also just in welding process in various degree insulating barrier to winding cause to a certain degree ablation, thereby the insulation property of winding have been reduced, and when in welding process, pressurizeing as electric resistance welding, must make armature shaft cause in various degree flexural deformation, bring very burden for the follow-up manufacturing work of motor, also influence the normal operation of motor, shorten the useful life of motor, if will address these problems, best scheme is exactly not adopt heating, the connecting mode of pressurization, and adopt the mode of cold connection.
The object of the present invention is to provide a kind of technology simple, be convenient to implement, interface is firm, constant product quality, applicable to the direct current machine of all kinds of, any commutator segment group number, saves a large amount of electric energy, the direct current machine winding of reduction motor production cost and the stamping connecting method of commutator.
The present invention is achieved by the following technical solutions:
A kind of stamping connecting method that is used for direct current machine winding and commutator mainly utilizes the existing pneumatic or electric press source of factories and miness, adopts the mode of punching press with staking punch motor windings and commutator to be pressed into one.
When above-mentioned winding and commutator carry out pressing, make a part of flexural deformation of cell wall end, both sides, cover on winding, make firm being connected as one of motor windings and commutator by punching press.
The staking punch section that above-mentioned this method adopted is a W shape structure.
Adding man-hour, motor windings is placed in the groove of commutator, use the special staking punch punching press motor windings and the interface of commutator then, make the winding conducting wire compressive deformation, meanwhile, end part flexural deformation under the punching press of staking punch of commutator cell wall, thus the lead of upper and lower layer winding and commutation tank both sides are combined as a whole.
The present invention has the following advantages:
1, technology is simple, is convenient to implement, and is applicable to the direct current machine of all kinds of, any commutator segment group number.
2, energy-saving effect significantly, reduce production costs, application range of products is wide.
3, interface is firm, constant product quality.
4, the required auxiliary facility of the enforcement of this method is few, than welding manner saves energy such as electric resistance weldings more than 10 times.
Describe in further detail below in conjunction with embodiment:
Fig. 1 is a working state schematic representation of the present invention.
Among the figure: 1 staking punch, 2 motor windings leads, 3 commutators
Embodiment 1: adopt cylindric staking punch, with pneumatic punching press source.
In use, cylindric staking punch 1 is aimed at motor windings lead 2, under the drive in pneumatic punching press source, sweep away then, at first the pressure head in the middle of the staking punch 1 contacts with motor windings lead 2, and make its pressurized transversely deforming, the cell wall of the winding conducting wire 2 extruding commutators 3 of distortion simultaneously, make cell wall that certain deformation also take place, meanwhile the stamping knife of staking punch 1 end makes a part of flexural deformation of both sides, cell wall top, tightly cover top at motor windings lead 2, so just finished the connection of a point, action and so forth just can be finished connecting of whole motor windings and commutator.
Embodiment 2: adopt polygon prism shape staking punch, use the electric press source.
Job order is the same, adopts the electric press source, carries out connecting of motor windings and commutator successively, and interface is firm.
Embodiment 3: adopt the flat column staking punch, adopt any of pneumatic or electric press source.
Job order is the same, adopts pneumatic or electric press source, carries out connecting of motor windings and commutator successively, and interface is firm.
