Description

The shaped device of the flat split pin of railway wagon brake

Technical field

The utility model relates to a kind of shaped device for the flat split pin of railway wagon brake.

Background technology

The flat split pin of railway wagon brake is widely used in the connection of all kinds of parts 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 the moulding core bar 13 of two module belows, two modules and moulding core bar 13 are connected with propulsion plants such as cylinder separately or oil cylinder (not shown) respectively, left and

right module

11,12 is provided with the die cavity matching, its forming process is: 1) rod member 14 is placed between two

modules

11,12 and moulding core bar 13, moulding core bar 13 is aimed at the middle part of rod member 14; 2) oil cylinder pushing moulding core bar 13 up, rod member 14 bendings are pushed between two modules, simultaneously two modules start close under the promotion of oil cylinder separately; 3) moulding core bar 13 exits, and plug 15 is penetrated between rod member 14; 4) promote two

modules

11,12 until contact is carried out die mould to rod member 14; 5) unclamp two modules, extract plug 15 out, obtain split pin; The shortcoming of this technique is: 1) rod member 14 is in being pushed into the process of 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 guarantee, and die life is short; 2) power set that relate to are more, operation is many, and not only energy consumption is higher, and production efficiency is lower, causes production cost higher.

Utility model content

The purpose of this utility model is for prior art above shortcomings, and the shaped device of the flat split pin of a kind of railway wagon brake is provided, and it has advantages of 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 utility model, comprise left module, right module, left and right module is provided with the die cavity matching, the rear end that it is characterized in that left and right module is hinged by bearing pin, rear in left and right module is provided with slide block, and the front center of slide block is provided with slot to make way; In the place ahead of left and right module, be provided with the plug connecting firmly with support, plug is parallel with bearing pin, and the front end of the left and right module all extension spring by is separately connected with support, at least one side of plug, is also provided with the locating piece connecting firmly with support.

The utility model using method is as follows: 1) rod member is put on plug, the rod member at the left and right two ends of plug about equally, and keeps level by locating piece; 2) by the left and right module of slipper push, around the bearing pin that connects the two, do rotation in opposite directions simultaneously, the front end of left and right module inwardly pushes the two ends of rod member simultaneously, make rod member folding around plug, until rod member middle part enter 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 split pin.

In forming process, because left and right module is inwardly pushed rod member, made it folding simultaneously, the friction zone of rod member and module is little, frictional resistance is little, and surface of the work is difficult for scratching, and product quality is improved, and die life is long; Owing to only needing power set, and operation is few, has advantages of that energy consumption is low, production efficiency is high, production cost is low;

As further improvement of the utility model, 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; Roller can become rolling friction by the friction of slide block and two modules, can further reduce the resistance of propelling and the wearing and tearing of device;

In sum, the utlity model has good product quality, energy consumption is low, production efficiency is high, production cost is low advantage.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

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 matching, the rear end of left module 1 and right module 2 is hinged by bearing pin 3, at the rear of left module 1 and right module 2, is provided with slide block 4, and the front center of slide block 4 is provided with slot to make way 5, in slide block 4 front ends 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; In the place ahead of left module 1 and right module 2, be provided with the plug 7 connecting firmly with support (not shown), plug 7 is parallel with roller 6 with bearing pin 3, the front end of left module 1 and the right module 2 all extension spring 8 by is separately connected with support, is also provided with the locating piece 9 connecting firmly with support in the left side of plug 7.

During moulding, slide block 4 is connected with the piston rod of hydraulic press, using method of the present utility model is as follows: 1) rod member 10 is put on plug 7, the rod member at plug 7 left and right two ends about equally, and by locating piece 9 maintenance levels; 2) descending by slide block 4, promote the rotation that left and

right module

1,2 is done in opposite directions around the bearing pin 3 that connects the two simultaneously, the front end of left and

right module

1,2 inwardly pushes the two ends of rod member 10 simultaneously, make rod member 10 folding around plug 7, until rod member 10 middle parts enter left and

right module

1,2 die cavity, complete doubling, and carry out die mould; 3) slide block 4 returns, and stops promoting left and

right module

1,2 and makes its state that affranchises, and left and right module resets, opens under the effect of extension spring 8; 4) extract plug 7 out, obtain split pin.

In forming process, compared with prior art, because left and

right module

1,2 is inwardly pushed rod member 10, made it folding simultaneously, the friction zone of rod member 10 and two modules is little, frictional resistance is little, surface of the work is difficult for scratching, and product quality is improved, and die life is long; Owing to only needing a power set hydraulic press, and do not use moulding core bar, also, without exiting, operation is few, has advantages of that energy consumption is low, production efficiency is high, production cost is low; Roller 6 can become rolling friction by the friction of slide block 4 and two modules, can further reduce the resistance of propelling and the wearing and tearing of device.
