Abstract
The invention discloses a commutator segment of a commutator. The commutator segment is one of a plurality of independent segments distributed on the circumference of the commutator. The commutator segment is characterized in that each commutator segment has a hollow structure and is formed by a thin-wall copper plate stamped piece after folding, the thickness of the stamped piece being no greater than 1 mm. The commutator segment is suitable for large-size groove-type or hook-type commutators, can greatly reduce the manufacturing cost of commutator products, and can effectively improve the mechanical strength and overspeed performance of commutator products.
Description
The present invention is the divisional application of " a kind of commutator segment of commutator ", the applying date of original application: on February 8th, 2014; Application number: 201410046896.7; Invention and created name: a kind of commutator segment of commutator.
Technical field:
The present invention relates to a kind of commutator, be specifically related to a kind of commutator segment of commutator.
Background technology:
Commutator product mainly contains Hooked reverser, tank commutator and end commutator three kinds.Wherein, the major part of Hooked reverser is the hook commutator segment with hook part, and hook commutator segment is along the circle distribution independently many of commutator, and every hook commutator segment is combined with commutator matrix by its fixing feet.The hook commutator segment overwhelming majority of tradition Hooked reverser is obtained by stretching copper section bar, also only a few is had to adopt global copper volume (to roll into cylindricality copper shell shape by copper coin, as the patent No. 201220283301.6, patent name " commutator " or the patent No. 201220083734.7, technical scheme disclosed by patent name " the copper volume for commutator makes ") cut rear obtaining, the hook commutator segment of the Hooked reverser obtained with said method is also solid construction, for large gauge Hooked reverser, the overall dimension of hook commutator segment is also large, obvious cost also can improve greatly, the Heavy Weight of hook commutator segment simultaneously, very large centrifugal force can be produced during work, and the adhesion of hook commutator segment when Hooked reverser injection mo(u)lding and between commutator matrix is limited to prior art can not have significant improvement, so just have a strong impact on mechanical strength and the hypervelocity performance of Hooked reverser product, mechanical strength and the hypervelocity performance of Hooked reverser product can not be further enhanced, the application of large gauge Hooked reverser is limited significantly.
Summary of the invention:
In view of the deficiency of background technology, object of the present invention aims to provide one and is applicable to large gauge Hooked reverser, greatly can reduce the manufacturing cost of commutator product, and effectively improves the mechanical strength of commutator product and the commutator segment of hypervelocity performance.
The present invention takes following technical scheme:
A commutator segment for commutator, is one of many separate pieces circumferentially distributing at commutator, it is characterized in that: every commutator segment self there is hollow-core construction, the thin-walled copper coin stamping that every commutator segment is no more than 1mm by thickness is formed after bending; Commutator segment is made up of sheet body, hook part and fixed foot portion; thin-walled copper coin stamping is symmetrical slab construction before bending; the left and right sides of thin-walled copper coin stamping is provided with the dovetail forming commutator segment fixed foot portion; formed after the sheet body of commutator segment is performed for more than the bending of 90 ° to the direction, the back side of thin-walled copper coin stamping by the left and right sides of thin-walled copper coin stamping simultaneously; the top of thin-walled copper coin stamping is provided with left and right hook tabs, and left and right hook tabs is to the hook part forming commutator segment after the frontal of thin-walled copper coin stamping is performed for more than the bending of 90 °.
Have employed the commutator segment of the commutator of technique scheme, maximum innovative point be make every commutator segment self achieve hollow-core construction, it is different from by the obtained solid commutator segment of stretching copper section bar, also be different from and cut rear obtained commutator segment by copper pipe or global copper cut roll, Advantageous Effects of the present invention is: 1. under the constant prerequisite of the overall dimension of commutator segment, the materials of obvious copper material obtain a large amount of savings, thus cost is reduced greatly, for all the more so large gauge Hooked reverser; 2. the weight of commutator segment can reduce greatly, the centrifugal force produced during work also can reduce greatly, and commutator segment is when commutator injection mo(u)lding, the plastic material of commutator matrix can be injected into the hollow interior of commutator segment, adhesion between commutator segment and commutator matrix can obtain enhancing to a certain extent, the reduction of centrifugal force and the enhancing of adhesion all can make the mechanical strength of commutator product and hypervelocity performance be improved significantly, thus effectively expand the range of application of large gauge Hooked reverser.
Accompanying drawing illustrates:
The present invention has following accompanying drawing:
Fig. 1 is the shape assumption diagram of hook commutator segment,
Fig. 2 be Fig. 1 overlook directional diagram,
Fig. 3 is the expansion view of Fig. 1.
Embodiment:
As shown in Figure 1,2 and 3, the commutator segment of commutator of the present invention, for the hook commutator segment of Hooked reverser, for one of many separate pieces circumferentially distributing at Hooked reverser, every hook commutator segment self there is hollow-core construction, the thin-walled copper coin stamping that every hook commutator segment is no more than 1mm by thickness is formed after bending, and the specification of thin-walled copper coin generally selects the wall thickness of 1mm or 0.8mm.Hook commutator segment is by sheet body D, hook part E and fixed foot portion F composition, as shown in Figure 3, thin-walled copper coin stamping is symmetrical slab construction before bending, the left and right sides 13 of thin-walled copper coin stamping is provided with two dovetails 15 forming commutator segment fixed foot portion F, the sheet body D of commutator segment is formed after being performed for more than the bending of 90 ° (being generally 91-93 °) to the direction, the back side of thin-walled copper coin stamping along crease line 14 by the left and right sides 13 of thin-walled copper coin stamping simultaneously, the top of thin-walled copper coin stamping is provided with left and right hook tabs 12, left and right hook tabs 12 forms the hook part E of commutator segment be performed for more than the bending of 90 ° to the frontal of thin-walled copper coin stamping along crease line 11 after.
The hook commutator segment of above-mentioned Hooked reverser, hollow-core construction is have employed with traditional maximum not being both, not only copper material materials are economized, reduce cost, simultaneously lightweight, the centrifugal force produced during work also can reduce greatly, and the adhesion between commutator segment and commutator matrix can be enhanced, thus the mechanical strength of commutator product and hypervelocity performance are improved, expand the range of application of large gauge grooved or Hooked reverser.
