Abstract
The utility model discloses a kind of Novel commutator copper sheet, comprise main leaf body and two hooks, main leaf body has fan shaped cross section, the lateral surface of main leaf body is arc surface, left and right side is inclined-plane, medial surface connects with hook, it is characterized in that: the centre of described main leaf body is provided with the hollow out die cavity of the bar shaped 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 between two hooks.The utility model can greatly strengthen commutator shaping time and phenolic moulding powder between adhesion, reduce own wt simultaneously, thus effectively improve the hypervelocity performance of commutator product.
Description
Technical field:
The utility model relates to commutator topology field, is specifically related to a kind of improvement invention of copper segment.
Background technology:
Commutator product mainly divides Hooked reverser, tank commutator and end commutator three kinds.The essential structure of the copper sheet of Hooked reverser or tank commutator is: comprise main leaf body and two hooks, main leaf body has fan shaped cross section, the lateral surface of main leaf body is arc surface, left and right side is inclined-plane, medial surface connects with hook, when commutator is shaping, copper segment after screening together with phenolic moulding powder pressure injection, for ensureing to leave reliable insulation distance between adjacent copper segment, being plugged with mica sheet between adjacent copper segment or offering insulation tank.The hypervelocity performance of commutator product weighs a most important technical indicator of commutator quality, and the hypervelocity performance of commutator product will be improved, first want it is considered that strengthen commutator shaping time copper segment and phenolic moulding powder between adhesion, and this is generally the structure of the hook by improving copper segment, quantity or arrange reinforcing ring to realize, because the main leaf body of each copper segment when commutator is shaping very near and and there is no favourable impetus between phenolic moulding powder, and often centre arranges mica sheet, so all the time, whom various equivalent modifications do not have can consider to improve adhesion between copper segment and phenolic moulding powder by the architecture advances of main leaf body, therefore the hypervelocity performance of commutator product 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 greatly strengthen commutator shaping time and phenolic moulding powder between adhesion, reduce own wt simultaneously, thus effectively improve the Novel commutator copper sheet of commutator product hypervelocity performance.
The utility model takes following technical scheme:
A kind of Novel commutator copper sheet, comprise main leaf body and two hooks, main leaf body has fan shaped cross section, the lateral surface of main leaf body is arc surface, left and right side is inclined-plane, medial surface connects with hook, it is characterized in that: the centre of described main leaf body is provided with the hollow out die cavity of the bar shaped 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 between two hooks.
Have employed the copper segment of technique scheme, unlike the prior art, it also by the architecture advances of the main leaf body to copper segment strengthen commutator shaping time and phenolic moulding powder between adhesion, its operation principle is: arrange hollow out die cavity 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 commutator shaping, phenolic moulding powder is fully filled to enter in hollow out die cavity and formed between the main leaf body of copper segment and is firmly combined, the setting of hollow out die cavity simultaneously reduces the weight of copper segment self, due to the enhancing of adhesion and alleviating of weight, thus effectively improve the hypervelocity performance of commutator product, the hypervelocity performance of commutator product is further enhanced on the basis of existing technology, thus better meet the more and more higher rate request of electric tool.
Accompanying drawing illustrates:
The utility model has following accompanying drawing:
Fig. 1 is side surface direction view of the present utility model,
Fig. 2 is the left view of Fig. 1.
Embodiment:
As shown in the figure, a kind of Novel commutator copper sheet of the present utility model, comprise main leaf body 1 and two hooks 2, main leaf body 1 has fan shaped cross section, the lateral surface 1a of main leaf body 1 is arc surface, left and right side 1b is inclined-plane, medial surface 1c connects with hook 2, the centre of described main leaf body 1 is provided with the hollow out die cavity 3 of the bar shaped arranged along main leaf body short transverse, hollow out die cavity 3 is provided with left and right opening to be run through outward from the left and right side 1b of main leaf body, be provided with interior side opening 4 to run through outward from the medial surface 1c of main leaf body, interior side opening 4 is between two hooks 2.
