Abstract

The utility model discloses a rivet commutator reinforcing ring die which comprises a movable die body and a bottom die body which are vertically arranged. The rivet commutator reinforcing ring die is characterized in that the movable die body comprises an upper template, a middle template and a lower template. After being fixedly connected, the middle template and the lower template are movably connected below the upper template in a hanging mode through screws. An upper spring is arranged between the upper template and the middle template. An upper puncher pin is fixedly arranged at the bottom of the upper template. An upper positioning ring is fixedly arranged at the bottom of the lower template. The upper puncher pin movably penetrates through the middle template, the lower template and the upper positioning ring. The bottom die body comprises a bottom die upper plate and a bottom die lower plate. The bottom die upper plate is fixedly connected with the bottom die lower plate. A lower puncher pin and a lower positioning ring are arranged on the top face of the bottom die upper plate. The lower positioning ring is fixedly arranged. The lower puncher pin is movably arranged inside the lower positioning ring. A lower spring is arranged at the bottom of the lower puncher pin, the upper puncher pin is right opposite to the lower puncher pin in a vertical mode, and the upper positioning ring is right opposite to the lower positioning ring in a vertical mode. According to the rivet commutator reinforcing ring die, automatic tight riveting of an upper reinforcing ring and a lower reinforcing ring of a commutator can be achieved inside the commutator, the efficiency is improved, and the labor intensity is reduced.

Description

Riveting commutator strengthening ring mould

Technical field

The utility model relates to a kind of mould, is specifically related to a kind of riveting commutator strengthening ring mould.

Background technology

For the intensity and the hypervelocity performance that improve commutator, a lot of commutators inside is equipped with reinforcing ring, in the reinforcement annular groove that reinforcing ring need to be provided with at commutator copper bar, is riveted tightly fixing.At present, during the riveting commutator strengthening ring, most of producer, by manually carrying out, also has minority producer to utilize mould to carry out, but the reinforcing ring up and down of commutator separately riveted tightly, and efficiency is low, and labor strength is large.

Summary of the invention

In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of can realize the upper and lower reinforcing ring of commutator automatically riveting tightly in commutator, raises the efficiency, and reduces the riveting commutator strengthening ring mould of labour intensity.

The utility model takes following technical scheme to complete:

Riveting commutator strengthening ring mould, comprise dynamic model setting up and down and bed die, it is characterized in that: described dynamic model comprises cope match-plate pattern, middle template and lower bolster, middle template be connected on the cope match-plate pattern below by the screw movable hanging after lower bolster is fixedly connected with, be provided with upper spring between cope match-plate pattern and middle template, the bottom of cope match-plate pattern is fixed with upper punch, and the bottom of lower bolster is fixed with centring ring, and upper punch is movable through middle template, lower bolster and upper centring ring; Described bed die comprises bed die upper plate and bed die lower plate, the bed die upper plate is fixedly connected with the bed die lower plate, and the end face of bed die upper plate is provided with low punch and lower centring ring, and lower centring ring is fixedly installed, low punch is movable the setting in lower centring ring, and the bottom of low punch is provided with lower spring; Upper punch and low punch up and down over against, upper centring ring and lower centring ring up and down over against.

The riveting commutator strengthening ring mould of said structure, during matched moulds, at first by upper and lower centring ring, commutator is accurately located, then going up low punch acts on respectively the inboard cell wall of strengthening up and down annular groove that commutator copper bar is provided with and makes it to produce distortion, thereby the disposable interior upper and lower reinforcing ring of annular groove of strengthening is up and down riveted tightly fixing simultaneously, raise the efficiency, reduce labour intensity.

The accompanying drawing explanation

The utility model has the following drawings:

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

Fig. 2 is the working state figure of the utility model while approaching matched moulds,

The I section enlarged drawing that Fig. 3 is Fig. 2.

The specific embodiment

With reference to accompanying drawing, riveting commutator strengthening ring mould of the present utility model, comprise dynamic model setting up and down and bed die, described dynamic model comprises cope match-plate pattern 4, middle template 6 and lower bolster 7, middle template 6 be connected on cope match-plate pattern 4 belows by screw 5 movable hangings after lower bolster 7 is fixedly connected with, be provided with upper spring 1 between cope match-plate pattern 4 and middle template 6, the bottom of cope match-plate pattern 4 is fixed with upper punch 2, the bottom of lower bolster 7 is fixed with centring ring 3, and upper punch 2 is movable through middle template 6, lower bolster 7 and upper centring ring 3; Described bed die comprises bed die upper plate 8 and bed die lower plate 9, bed die upper plate 8 is fixedly connected with bed die lower plate 9, the end face of bed die upper plate 8 is provided with low punch 12 and lower centring ring 11, lower centring ring 11 is fixedly installed, low punch 12 is interior movable setting of lower centring ring 11, and the bottom of low punch 12 is provided with lower spring 10; Upper punch 2 and low punch 12 up and down over against, upper centring ring 3 and lower centring ring 11 up and down over against.

The utility model is performed such work: bed die is fixed on work bench of punch press, dynamic model is arranged on the punch press unit head, during work, put workpiece template 13 between dynamic model and bed die, be placed with the commutator copper bar 14 that screening completes in the die cavity of workpiece template 13, be placed with upper and lower reinforcing ring 15 in the annular groove of reinforcement up and down of commutator copper bar 14, when the downward close bed die of dynamic model, lower bolster 7, workpiece template 13, at first bed die upper plate 8 contacts, now the top of upper and lower centring ring extend into respectively and strengthens up and down in annular groove, upper and lower reinforcing ring 15 being compressed, utilize upper and lower centring ring top cylindrical accurately to locate commutator copper bar 14 simultaneously, then dynamic model continues downwards, the top conical surface that upper low punch has acts on respectively the inboard cell wall 16 of strengthening up and down annular groove and makes it to produce distortion, thereby disposable upper and lower reinforcing ring is riveted tightly to be fixed on strengthen up and down in annular groove, raise the efficiency, reduce labour intensity.
