Abstract
The utility model discloses a magic flower punch of a steel plate with a square hole and a plum blossom hole. The magic flower punch of the steel plate with the square hole and the plum blossom hole comprises a direction guiding portion and a working portion, wherein the direction guiding portion is a cone, and a corner radius of a transiting section between the cone and the working portion is R. The improving principle of the magic flower punch of the steel plate with the square hole and the plum blossom hole is to utilize the cone to increase outward deformation expansive force, thereby reducing a positive pressure. By enlarging a base angle of R, the magic flower punch of the steel plate with the square hole and the plum blossom hole enables the tip portion of the plum blossom leaves to easily deform, thereby reducing the phenomenon of breaking the plum blossom leaves. The magic flower punch of the steel plate with the square hole and the plum blossom hole enables breaking of the root portion of the plum blossom leaves not to happen, improves the qualified ratio of HGM-D synthetic high friction process, and greatly lowers production cost. The HGM-D synthetic high friction brake-shoe steel back plum blossom punched by the magic flower punch after improvement is attractive in appearance, meets requirements of products and free of the phenomenon of breaking the plum blossom leaves.
Description
Technical field
The utility model relates to a kind of steel plate square hole plum blossom hole magic flower drift.
Background technology
Novel synthetic high abrasion brake block is the important accessory of present freight car braking equipment, since 2002, popularizes in an all-round way in China railways.The synthetic high abrasion brake block of the HGM-D that uses at present occurs sometimes in process of production that friction piece surface blistering, crackle, steel backing plum blossom hole are not full, steel backing and the phenomenon such as the friction piece bonding is insecure, affect the outward appearance of novel synthetic high abrasion brake block, can affect its serviceability when serious, jeopardize traffic safety.
It is to adopt the straight cylinder guiding that the synthetic high abrasion brake block steel backing plum blossom hole magic flower of existing HGM-D, magic flower rush application technology, the little R moulding in base angle, and shortcoming is that the plum blossom lobe phenomenon that falls of breaking easily occurs.
Through force analysis, it is that the plum blossom lobe is subjected to that normal pressure is too large, plum blossom lobe distortion difficulty that the break reason that falls of plum blossom lobe occurs, thereby makes part plum blossom lobe break.
The utility model content
The purpose of this utility model is for above-mentioned situation, and a kind of plum blossom lobe steel plate square hole plum blossom hole magic flower drift of phenomenon of falling that breaks that reduces is provided.
The purpose of this utility model realizes by following technical proposals:
A kind of steel plate square hole plum blossom hole magic flower drift comprises targeting part and working portion, and targeting part is cone, and the knuckle radius of the changeover portion between cone and working portion is R.
As optimal way, the taper angles A of the cone of described targeting part is 14-21 °.
As optimal way, the taper angles A of the cone of described targeting part is 18 °.
As optimal way, the knuckle radius R=5 ± 1mm of described changeover portion.
As optimal way, the knuckle radius R=5mm of described changeover portion.
As optimal way, the whole height of described drift is 30 ± 2mm.
As optimal way, the whole height of described drift is 30mm.
The installation method of the synthetic high abrasion brake block steel backing plum blossom hole magic flower drift of HGM-D is: the magic flower bed die is arranged on the work bench of punch press plate, and the magic flower drift rushes fixed head by magic flower and is fixed on the punch press moving slide block.
The synthetic high abrasion brake block steel backing plum blossom magic flower implementation procedure of HGM-D is: move by slider of punch and realize that the plum blossom hole after the magic flower drift punctures to the synthetic Gao Mowa steel backing steel of HGM-D carries out magic flower.
Thereby improvement principle of the present utility model is to utilize cone to increase outside distortion expansive force to reduce normal pressure, by making R base angle increase, makes the distortion of plum blossom lobe tip curves easily, the phenomenon that falls thereby minimizing plum blossom lobe breaks.
The beneficial effects of the utility model: the utility model makes plum blossom lobe root not break, improved the rub qualification rate of process product of the synthetic height of HGM-D, decrease production cost, the synthetic high abrasion brake block steel backing plum blossom lobe outward appearance of the HGM-D that the magic flower drift after improvement is routed up is more attractive in appearance, more meet product requirement, without the plum blossom lobe phenomenon that falls of breaking.
Description of drawings
Fig. 1 is the structural representation of existing magic flower drift.
Fig. 2 is structural representation of the present utility model.
Wherein, 1 is targeting part, and 2 is working portion.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in the figure, a kind of steel plate square hole plum blossom hole magic flower drift comprises targeting part 1 and working portion 2, and targeting part 1 is cone, and the knuckle radius of the changeover portion between cone and working portion 2 is R.
The taper angles A of the cone of described targeting part is 14-21 °.
As preferably, the taper angles A of the cone of described targeting part is 18 °.
Knuckle radius R=5 ± the 1mm of described changeover portion.
As preferably, the knuckle radius R=5mm of described changeover portion.
The whole height of described drift is 30 ± 2mm.
As preferably, the whole height of described drift is 30mm.
The installation method of the synthetic high abrasion brake block steel backing plum blossom hole magic flower drift of HGM-D is: the magic flower bed die is arranged on the work bench of punch press plate, and the magic flower drift rushes fixed head by magic flower and is fixed on the punch press moving slide block.
The synthetic high abrasion brake block steel backing plum blossom magic flower implementation procedure of HGM-D is: move by slider of punch and realize that the plum blossom hole after the magic flower drift punctures to the synthetic Gao Mowa steel backing steel of HGM-D carries out magic flower.
Thereby improvement principle of the present utility model is to utilize cone to increase outside distortion expansive force to reduce normal pressure, by making R base angle increase, makes the distortion of plum blossom lobe tip curves easily, the phenomenon that falls thereby minimizing plum blossom lobe breaks.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
