Abstract

The utility model discloses a high-friction composite brake shoe steel mold for a railway vehicle. The high-friction composite brake shoe steel backing mold for the railway vehicle comprises an upper mold, a male mold connected with the upper mold and a female mold. The female mold is provided with a cavity matched with the male mold. The high-friction composite brake shoe steel backing mold for the railway vehicle is characterized in that axial sector grooves are formed in the corners, at the upper end of the side wall of the cavity, of the female mold respectively, each section groove is provided with a rolling column inside, and part of the outer circle of each rolling column is located outside the female mold. According to the high-friction composite brake shoe steel backing mold for the railway vehicle, a workpiece can be prevented from being strained, the production efficiency is improved, the service life of the mold is prolonged, and the production cost is reduced to a large extent.

Description

The mould of high friction composite brake shoe steel backing for rolling stock
Technical field
The utility model relates to the mould of high friction composite brake shoe steel backing for a kind of rolling stock.
Background technology
As shown in Figure 1, rolling stock is provided with watt nose 6 with the middle part of high friction composite brake shoe steel backing 5, and this watt of nose 6 is by mould punching moulding; The mould using at present as shown in Figure 2, comprises patrix 7, the punch 8 connecting with patrix 7, die 9, and die 9 is provided with the die cavity matching with punch 8; When moulding, brake shoe steel backing 5 need bear maximum force of sliding friction when die 9 corner through cavity lateral upper end, and not only workpiece is easily pulled, form waste product, and die is easy to wear, die change is frequent, reduce productivity ratio, caused higher die cost and production cost.
Utility model content
The purpose of this utility model is for prior art above shortcomings, and the mould of a kind of rolling stock with high friction composite brake shoe steel backing is provided, and it can avoid workpiece to be pulled, and enhances productivity and die life, significantly reduces production costs.
For achieving the above object, the mould of high friction composite brake shoe steel backing for rolling stock of the present utility model, comprise patrix, the punch connecting with patrix, die, die is provided with the die cavity matching with punch, it is characterized in that being equipped with axial scalloped recess in the die corner of cavity lateral upper end, in scalloped recess, be provided with roller, the part cylindrical of roller is positioned at outside die.
The utility model arranges roller by the die corner in cavity lateral upper end, when moulding, the force of sliding friction between workpiece and mould is herein become to force of rolling friction, the two friction greatly reduces, can avoid workpiece to be pulled, and improved die life, the die change cycle is long, and production efficiency greatly improves, and has significantly reduced production cost;
As further improvement of the utility model, the part cylindrical that roller is positioned at outside die is less than 1/4 of its whole cylindrical; Can avoid roller to be taken out of, guarantee normally to work;
In sum, the utility model can avoid workpiece to be pulled, and enhances productivity and die life, significantly reduces production costs.
Accompanying drawing explanation
Fig. 1 is the front view of high friction composite brake shoe steel backing.
Fig. 2 be existing mould front view.
Fig. 3 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, the mould of high friction composite brake shoe steel backing for this rolling stock, comprise patrix 1, the punch 2 connecting with patrix 1, die 3, die 3 is provided with the die cavity matching with punch 2, die 3 corners in cavity lateral upper end are equipped with axial scalloped recess, in scalloped recess, be provided with roller 4, the part cylindrical of roller 4 is positioned at outside die 3, and the part cylindrical that roller 4 is positioned at outside die 3 is less than 1/4 of its whole cylindrical.
The utility model arranges roller 4 by die 3 corners in cavity lateral upper end, when moulding, the force of sliding friction between workpiece 5 and mould is herein become to force of rolling friction, the two friction greatly reduces, can avoid workpiece to be pulled, and improved die life, the die change cycle is long, and production efficiency greatly improves, and has significantly reduced production cost.
