Abstract
The utility model discloses band reinforcing ring Hooked reverser, comprise commutation matrix and commutation copper sheet, mica sheet is inserted with between adjacent commutation copper sheet, 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, described reinforcing ring is ferrous material, and the location notch that described reinforcing ring is provided with by mica sheet positions; The centre of described main leaf body is provided with the hollow out die cavity arranged along main leaf body short transverse, 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 to run through outward from the medial surface of main leaf body, interior side opening is positioned at the centre position of upper and lower two fixing feet, described fixing feet is implanted in commutation matrix and phenolic moulding powder material strong bonded, fills phenolic moulding powder material and phenolic moulding powder material strong bonded in described hollow out die cavity.The utility model makes Hooked reverser have high strength, improves product hypervelocity performance.
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 main leaf body top of its commutation copper sheet.High strength, hypervelocity performance weigh an important technology index of Hooked reverser quality, and intensity and the hypervelocity performance of Hooked reverser will be improved, first want it is considered that strengthen Hooked reverser shaping time commutation copper sheet and phenolic moulding powder between adhesion, and this be generally by improve commutation copper sheet fixing feet structure, quantity or arrange reinforcing ring to realize.But the Hooked reverser of traditional band reinforcing ring, reinforcing ring is all position in the reinforcement annular groove of commutation copper sheet, reinforcing ring can produce with commutation copper sheet and contact, for avoiding the conduction between adjacent commutation copper sheet, so reinforcing ring is all the fiber material adopting high strength usually, instead of employing ferrous material, so just have influence on the intensity of Hooked reverser, so also just affect the hypervelocity performance of Hooked reverser.Also have, all the time, 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 aims to provide a kind of band reinforcing ring Hooked reverser having high strength, improve product hypervelocity performance.
The utility model takes following technical scheme:
Band reinforcing ring 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, mica sheet is inserted with between adjacent commutation copper sheet, 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, described reinforcing ring is ferrous material, the location notch that described reinforcing ring is provided with by mica sheet positions, and described reinforcing ring does not produce with commutation copper sheet when the reinforcement annular groove through commutation copper sheet and contacts; The centre of described main leaf body is provided with the hollow out die cavity arranged along main leaf body short transverse, 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 to run through outward from the medial surface of main leaf body, interior side opening is positioned at the centre position of upper and lower two fixing feet, described fixing feet is implanted in commutation matrix and phenolic moulding powder material strong bonded, fills phenolic moulding powder material and phenolic moulding powder material strong bonded in described hollow out die cavity.
The endoporus of described commutation matrix is provided with steel bushing.
The band reinforcing ring Hooked reverser of technique scheme, first, because the location notch of reinforcing ring by mica sheet positions, reinforcing ring does not contact with commutation copper sheet when the reinforcement annular groove through commutation copper sheet, so reinforcing ring can adopt ferrous material, so, Hooked reverser is just provided with high strength; Also have, unlike the prior art, Hooked reverser 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 interior side opening, when enabling commutator 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.Due to the raising of intensity, the alleviating of the enhancing of adhesion and 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.
