Abstract

The utility model discloses a hook type commutator, comprising a plurality of commutator segments fixed on a die body, wherein insulating grooves are arranged between the commutator segments for insulating. The hook type commutator is characterized in that the insulating grooves are arranged on the commutator segments, the commutator segments are connected before the insulating grooves are cut, the connected commutator segments form a cylindrical copper housing, the insulating grooves divide the connected commutator segments into commutator segments independent from each other. The hook type commutator is high in production efficiency, and low in production cost.

Description

A kind of hook commutator

Technical field

The utility model relates to a kind of commutator, what be specifically related to is a kind of improvement invention of hook commutator.

Background technology

Commutator generally is divided into three kinds of hook commutator, tank commutator and end commutators; Traditional hook commutator; Its commutator segment is independently stamping parts of slices, fixes through the die body of phenolic moulding powder compacting then, and filling phenolic moulding powder forms insulation tank naturally between every commutator segment.The hook commutator production process of said structure is many, and production efficiency is low, and production cost is high.

Summary of the invention

In view of the problem of known technology existence at present, the technical problem that the utility model will solve is to be to provide the hook commutator that a kind of production efficiency is high, production cost is low.

The utility model takes following technical scheme to accomplish:

A kind of hook commutator; Comprise some commutator segments, commutator segment is fixed on the die body, insulate through insulation tank between each commutator segment; It is characterized in that: insulation tank is left on commutator segment; All commutator segments are disjunctors before offering insulation tank, and the commutator segment of disjunctor forms a cylindricality copper shell, and said insulation tank is divided into independently commutator segment one by one with the commutator segment of disjunctor.

The beneficial effect of the utility model is: at first all commutator segments of hook commutator are disjunctors; All commutator segments can be used as a stamping parts and carry out punching press like this; Technology is simple, operation is few, has improved production efficiency, has reduced production cost; The last insulation tank (commutator segment of disjunctor is divided into independently commutator segment, and this moment, commutator segment being fixed by die body) of only need on the commutator segment of disjunctor, leaving gets final product.

Description of drawings

The utility model has following accompanying drawing:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is a commutator segment of leaving the preceding disjunctor of insulation tank.

Fig. 4 is the vertical view of Fig. 3.

Fig. 5 is the blanking figure of disjunctor commutator segment.

Embodiment

With reference to accompanying

drawing

1,2, this kind hook commutator comprises some commutator segments 1; Commutator segment 1 is fixed on the die body 2, and die body 2 is formed by phenolic moulding powder compacting, separates through insulation tank 3 between each commutator segment 1 and insulate; Said insulation tank 3 is left on commutator segment 1, and with reference to accompanying drawing 3,4, all commutator segments 1 are disjunctors before offering insulation tank 3; The commutator segment of disjunctor forms a cylindricality copper shell, and all commutator segments can be used as a stamping parts and carry out punching press like this, and technology is simple, operation is few; Improved production efficiency; Reduced production cost, shown in Figure 5 is the blanking figure of the disjunctor commutator segment of punching out Fig. 3, copper shell shown in 4, and Fig. 1, the said insulation tank 3 shown in 2 are divided into independently commutator segment 1 one by one with the commutator segment of disjunctor.

The manufacturing process of the utility model is such: at first blanking shown in Figure 5 is stamped out Fig. 3, the disjunctor commutator segment shown in 4; Then disjunctor commutator segment and die body 2 compactings are fixed together; On the disjunctor commutator segment, leave insulation tank 3 at last; The disjunctor commutator segment is divided into independently commutator segment 1 one by one, and the making of hook commutator is accomplished in commutator segment 1 crotch moulding subsequently.

Claims

1. hook commutator; Comprise some commutator segments, commutator segment is fixed on the die body, insulate through insulation tank between each commutator segment; It is characterized in that: insulation tank is left on commutator segment; All commutator segments are disjunctors before offering insulation tank, and the commutator segment of disjunctor forms a cylindricality copper shell, and said insulation tank is divided into independently commutator segment one by one with the commutator segment of disjunctor.
