Abstract
Commutator crotch shaping mold disclosed in the utility model, comprise upper and lower mould, it is characterized in that: patrix is made up of drift and die shank, the bottom of drift is provided with the shaping conical surface in cylindrical position, be provided with perforate in endface position, the internal diameter of perforate is slightly larger than the external diameter of integer commutator; Counterdie comprises cylindrical body, the upper surface central authorities of cylindrical body are provided with counterbore, the central authorities of counterbore are provided with the positioning core axle for integer commutator Internal hole positioning, the cylindrical body upper surface of counterbore outer rim is the support face of integer commutator crotch back, the cylindrical body upper surface of counterbore outer rim is also provided with multiple spacing preiection for integer commutator circumference location, the width of spacing preiection is slightly less than the distance between the adjacent crotch of integer commutator, and the height of spacing preiection is greater than the material thickness of integer commutator crotch back.The utility model is specifically designed to commutator crotch integer after forming, and structure is simple, efficiency is high, crotch integer is effective, effectively reduces the generation of product percent defective.
Description
Technical field
The utility model relates to a kind of commutator die, is specifically related to a kind of commutator crotch shaping mold.
Background technology
Commutator is mainly applied in electric tool.Commutator divides hook, grooved and face type three kinds, and wherein Hooked reverser is because copper bar top is provided with crotch and gains the name, and the crotch of Hooked reverser after shaping, is often had situation about breaking and occurs, so need to be repaired by crotch integer.At present, because do not have special shaping mold to carry out crotch integer to it, so crotch needs to carry out integer one by one, and integer effect is bad, sometimes also can destroy the crotch of adjacent normal hook, make product high on this percent defective, efficiency is low simultaneously.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is that providing a kind of is specifically designed to commutator crotch integer after forming, and structure is simple, efficiency is high, crotch integer is effective, effectively reduces the commutator crotch shaping mold that product percent defective produces.
The utility model is implemented by the following technical programs:
Commutator crotch shaping mold, comprise upper die and lower die, it is characterized in that: described patrix is made up of the drift be fixedly connected with and die shank, the bottom of drift is provided with the shaping conical surface in cylindrical position, perforate is provided with in endface position, the internal diameter of perforate is slightly larger than the external diameter of integer commutator, and the degree of depth of perforate is greater than the height of integer commutator; Described counterdie comprises cylindrical body, the upper surface central authorities of cylindrical body are provided with counterbore, the central authorities of counterbore are provided with the positioning core axle for integer commutator Internal hole positioning, the cylindrical body upper surface of counterbore outer rim is the support face of integer commutator crotch back, the cylindrical body upper surface of counterbore outer rim is also provided with multiple spacing preiection for integer commutator circumference location, the width of spacing preiection is slightly less than the distance between the adjacent crotch of integer commutator, and the height of spacing preiection is greater than the material thickness of integer commutator crotch back.
Described spacing preiection is provided with circumference uniform distribution everywhere in the cylindrical body upper surface of counterbore outer rim.
Adopt after technique scheme, all bad crotch of a commutator can on shaping mold once property obtain whole integer, efficiency is high, and crotch integer is effective simultaneously, and effectively reduce product percent defective and produce, structure is simple.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of commutator crotch shaping mold,
Fig. 2 is commutator crotch shaping mold structural representation in working order,
Fig. 3 be in Fig. 1 counterdie overlook directional diagram.
Detailed description of the invention
As shown in the figure, commutator crotch shaping mold of the present utility model, comprise upper die and lower die, described patrix is made up of the drift 2 be fixedly connected with and die shank 1, the bottom of drift 2 is provided with the shaping conical surface 4 in cylindrical position, be provided with perforate 3 in endface position, the internal diameter of perforate 3 is slightly larger than the external diameter of integer commutator 100, and the degree of depth of perforate 3 is greater than the height of integer commutator 100; Described counterdie comprises cylindrical body 9, the upper surface central authorities of cylindrical body 9 are provided with counterbore 8, the central authorities of counterbore 8 are provided with the positioning core axle 5 for integer commutator 100 Internal hole positioning, the cylindrical body upper surface 7 of counterbore 8 outer rim is the support face of integer commutator crotch 101 back, the cylindrical body upper surface 7 of counterbore outer rim is also provided with four spacing preiections 6 for integer commutator 100 circumference location of circumference uniform distribution, the width of spacing preiection 6 is slightly less than the distance between the adjacent crotch 101 of integer commutator, and the height of spacing preiection 6 is greater than the material thickness of integer commutator crotch 101 back.
The integer process of above-mentioned shaping mold to crotch is: by the crotch back of commutator towards transferring on counterdie, positioning core axle positions commutator endoporus, faced by support, commutator crotch back carries out rest, spacing preiection positions commutator circumference, then commutator aimed at by drift, the cylindrical of commutator is inserted in the perforate of drift, the shaping conical surface of drift and the interior side contacts of crotch, then by beaing die shank, so the shaping conical surface can carry out integer to all bad crotches simultaneously, in integer final stage, the bottom of drift can produce with the end face of spacing preiection and contact, one is illustrate that crotch integer puts in place, two is drift can be avoided to carry out impact to the material of commutator crotch back cause damage.Thus, the utility model structure is simple, efficiency is high, crotch integer is effective, effectively can reduce product percent defective and produce.
