Abstract
The utility model discloses a kind of Hooked reverser, comprise commutation matrix and commutation copper sheet, it is characterized in that: described commutation copper sheet comprises the main leaf body of top tape crotch and upper and lower two fixing feet, upper fixing feet is quadrilateral structure, the top margin of upper fixing feet is inclined upwardly and connects with the top margin of main leaf body, the base of upper fixing feet has being inclined upwardly of direction same with top margin and designs, lower fixing feet is triangle dovetail configuration, the centre of described main leaf body is provided with upper and lower two hollow out die cavities along main leaf body short transverse, upper and lower hollow out die cavity is corresponding with upper and lower fixing feet respectively, hollow out die cavity is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening carry out outward running through from the medial surface of main leaf body and pass through in the middle of corresponding fixing feet, phenolic moulding powder material and phenolic moulding powder material strong bonded is filled in described hollow out die cavity.The utility model can solve the problem of commutator MATRIX CRACKING near crotch, makes product possess stronger hypervelocity performance simultaneously.
Description
Technical field
The utility model relates to commutator topology field, is specifically related to a kind of Hooked reverser.
Background technology
Hooked reverser is the one that in all commutator products, accounting is maximum, and Hooked reverser has crotch and gains the name because of the top of its commutation copper sheet.At present, the subject matter that Hooked reverser exists has: 1. when the commutation copper sheet sheet number of Hooked reverser is less, the crotch width at main leaf body top and gauge are just often larger, the stress of crotch when brake forming is just very large, the commutator matrix near crotch is easily caused to occur cracking phenomena, thus the hypervelocity performance of Hooked reverser is impacted, directly cause product rejection time serious; 2. at the hypervelocity aspect of performance improving Hooked reverser, consider at present usually only the structure of the fixing feet by improving commutation copper sheet, quantity strengthen Hooked reverser shaping time commutation copper sheet and phenolic moulding powder between adhesion, whom various equivalent modifications do not have can consider to strengthen adhesion between commutation copper sheet and phenolic moulding powder by the architecture advances of main leaf body, therefore the hypervelocity performance of Hooked reverser can not improve to a certain extent further, better can not meet the more and more higher rate request of electric tool.
Summary of the invention
In view of the deficiency of background technology, the purpose of this utility model aim to provide a kind of can solve commutator MATRIX CRACKING near crotch problem, make product possess the Hooked reverser of the performance that exceeds the speed limit more by force simultaneously.
The utility model takes following technical scheme:
A kind of Hooked reverser, comprise by the commutation matrix of phenolic moulding powder material compacting and the commutation copper sheet in the even screening of commutation matrix excircle, it is characterized in that: described commutation copper sheet comprises the main leaf body of top tape crotch and is located at two fixing feet up and down of main leaf body medial surface, upper and lower two fixing feet are implanted in commutation matrix and phenolic moulding powder material strong bonded, upper fixing feet is quadrilateral structure, the top margin of upper fixing feet is inclined upwardly and connects with the top margin of main leaf body, the base of upper fixing feet has being inclined upwardly of direction same with top margin and designs, lower fixing feet is triangle dovetail configuration, the centre of described main leaf body is provided with upper and lower two hollow out die cavities along main leaf body short transverse, upper and lower hollow out die cavity is corresponding with upper and lower fixing feet respectively, hollow out die cavity is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening carry out outward running through from the medial surface of main leaf body and pass through in the middle of corresponding fixing feet, phenolic moulding powder material and phenolic moulding powder material strong bonded is filled in described hollow out die cavity.
The top margin of fixed pin is inclined upwardly angle between 20 ° to 25 °.
The interior side opening of described hollow out die cavity has enlarging design.
The Hooked reverser of technique scheme, first, the top margin of upper fixing feet is inclined upwardly and connects with the top margin of main leaf body, which adds the intensity of the commutation copper sheet of crotch root, so the bending stress of crotch when brake forming just concentrates on above commutation copper sheet itself, so solve the problem of commutator MATRIX CRACKING near crotch, avoid the impact that Hooked reverser hypervelocity performance is caused; In addition, unlike the prior art, Hooked reverser also by the architecture advances of the main leaf body to commutation copper sheet strengthen Hooked reverser shaping time and phenolic moulding powder between adhesion, namely hollow out die cavity is set in the centre of main leaf body, and hollow out die cavity is provided with left and right opening and interior side opening, when enabling Hooked reverser shaping, phenolic moulding powder is fully filled to enter in hollow out die cavity and formed between the main leaf body of commutation copper sheet and is firmly combined, and the setting of hollow out die cavity simultaneously reduces the weight of commutation copper sheet self.Owing to solving the enhancing of commutator MATRIX CRACKING problem and adhesion, the alleviating of weight, thus effectively improve the hypervelocity performance of Hooked reverser, the hypervelocity performance of Hooked reverser is further enhanced on the basis of existing technology, thus better meets the more and more higher rate request of electric tool.
