Technical field
The present invention relates to a kind of shaped device for the flat split pin of railway wagon brake and technique.
Background technology
The flat split pin of railway wagon brake is widely used in the connection of all kinds of part on axle, and its structure as shown in Figure 1; At present, the flat split pin of railway wagon brake generally adopts U-shaped mold forming method, its shaped device and technique are as shown in Figures 2 to 6, its shaped device comprises left module 11, right module 12, is positioned at shaping core bar 13 below two modules, two modules and shaping core bar 13 are connected with propulsion plants such as respective cylinder or oil cylinder (not shown) respectively, left and right module 11,12 is provided with the die cavity matched, its forming process is: 1) be placed in by rod member 14 between two modules 11,12 and shaping core bar 13, the middle part of rod member 14 aimed at by shaping core bar 13; 2) the shaping core bar of oil cylinder pushing 13 up, rod member 14 bending is pushed between two modules, simultaneously two modules start close under the promotion of respective oil cylinder; 3) shaping core bar 13 exits, and is penetrated by plug 15 between rod member 14; 4) promote two modules 11,12 until contact, die mould is carried out to rod member 14; 5) unclamp two modules, extract plug 15 out, obtain flat split pin; The shortcoming of this technique is: 1) rod member 14 is in the process being pushed into two modules, and the friction head of district, the frictional resistance of it and module are large, and not only surface of the work easily scratches, and product quality cannot ensure, and die life is short; 2) power set related to are more, operation is many, and not only energy consumption is higher, and production efficiency is lower, cause production cost higher.
Summary of the invention
The object of the invention is for prior art above shortcomings, provide shaped device and the technique of the flat split pin of a kind of railway wagon brake, the advantage that it has good product quality, energy consumption is low, production efficiency is high, production cost is low.
For achieving the above object, the shaped device of the flat split pin of railway wagon brake of the present invention, comprise left module, right module, left and right module is provided with the die cavity matched, it is characterized in that the rear end of left and right module is by hinge, is provided with slide block at the rear of left and right module, the front center of slide block is provided with slot to make way, in the slip front of slot to make way both sides, be provided with the roller parallel with plug, the part cylindrical of roller is positioned at outside slide block; Be provided with the plug connected firmly with support in the front of left and right module, plug is parallel with bearing pin, and the front end of left and right module is all connected with support by respective extension spring, is also provided with at least side of plug the locating piece connected firmly with support.
Be applicable to the moulding process of the flat split pin of railway wagon brake of above-mentioned shaped device, comprise the following steps: 1) be put on plug by rod member, the rod member at the left and right two ends of plug is roughly equal, and keeps level by locating piece; 2) by rotation that the bearing pin of the left and right module of slipper push simultaneously both connect is done in opposite directions, the front end of left and right module inwardly extrudes the two ends of rod member simultaneously, rod member is folded around plug, until enter in the middle part of rod member left and right module die cavity, complete doubling; 3) stop promoting left and right module and make its state that affranchises, left and right module resets, opens under the effect of extension spring; 4) extract plug out, obtain flat split pin.
In forming process, because left and right module inwardly extrudes rod member, makes it fold simultaneously, the friction zone of rod member and module is little, frictional resistance is little, the friction of slide block and two modules can be become rolling friction by roller, the wearing and tearing of resistance and the device advanced can be reduced further, surface of the work not easily scratches, and product quality is improved, and die life is long; Owing to only needing power set, and operation is few, has the advantage that energy consumption is low, production efficiency is high, production cost is low;
In sum, the advantage that the present invention has good product quality, energy consumption is low, production efficiency is high, production cost is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 7 to 10, the shaped device of the flat split pin of this railway wagon brake, comprise left module 1, right module 2, left and right module is provided with the die cavity matched, the rear end of left module 1 and right module 2 is hinged by bearing pin 3, and be provided with slide block 4 at the rear of left module 1 and right module 2, the front center of slide block 4 is provided with slot to make way 5, in slide block 4 front end of slot to make way 5 both sides, be provided with roller 6, the part cylindrical of roller 6 is positioned at outside slide block 4; The plug 7 connected firmly with support (not shown) is provided with in the front of left module 1 and right module 2, plug 7 is parallel with roller 6 with bearing pin 3, left module 1 is all connected with support by respective extension spring 8 with the front end of right module 2, is also provided with the locating piece 9 connected firmly with support in the left side of plug 7.
Time shaping, slide block 4 is connected with the piston rod (not shown) of hydraulic press, corresponding to the moulding process of the split pin of above-mentioned shaped device, comprises the following steps: 1) rod member 10 is put on plug 7, the rod member at the left and right two ends of plug 7 is roughly equal, and keeps level by locating piece 9; 2) descending by slide block 4, promote the rotation that the bearing pin 3 of left and right module 1,2 simultaneously both connect is done in opposite directions, the front end of left and right module 1,2 inwardly extrudes the two ends of rod member 10 simultaneously, rod member 10 is folded around plug 7, until enter in the middle part of rod member 10 left and right module 1,2 die cavity, complete doubling, and carry out die mould; 3) slide block 4 returns, and stop promoting left and right module 1,2 and make its state that affranchises, left and right module resets, opens under the effect of extension spring 8; 4) extract plug 7 out, obtain flat split pin.
In forming process, compared with prior art, because left and right module 1,2 inwardly extrudes rod member 10, makes it fold simultaneously, the friction zone of rod member 10 and two modules is little, frictional resistance is little, surface of the work not easily scratches, and product quality is improved, and die life is long; Owing to only needing a power set hydraulic press, and do not use shaping core bar, also without the need to exiting, operation is few, has the advantage that energy consumption is low, production efficiency is high, production cost is low; The friction of slide block 4 and two modules can be become rolling friction by roller 6, can reduce the wearing and tearing of resistance and the device advanced further.
Implement moulding process of the present invention and also can adopt other structure, as the both sides at plug 7 all can arrange locating piece 9; Also slide block 4 can be replaced to control the rotation of two modules with two oil cylinders, they all belong to the protection domain of moulding process of the present invention.
