Abstract
The utility model relates to an axle forging swage block for railway vehicles, and belongs to the field of moulds. A first arc-shaped working surface is arranged in the middle of a cavity, a first step and a second step are respectively symmetrically arranged at two ends of the first working surface, a second arc-shaped working surface is arranged between the first step and the second step, and a third arc-shaped working surface is arranged outside the second step. The axle forging swage block for the railway vehicles has the advantages of being capable of guaranteeing the coaxiality of an axle neck, a wheel seat and an axle body, increasing working allowance of each part imperceptibly, shortening the length of the wheel seat, reducing the weight of a forged blank, and reducing norm of material consumption.
Description
Technical field
The utility model relates to a kind of railway vehicle axle and forges swage block, belongs to mould applications.
Background technology
In the process of axletree forging technology design, one of them emphasis is exactly that axletree rough forging after how making high-volume can effectively, omnibearing comprise finished product, leave enough machines to machining and add surplus, preventing has the forging casting skin after the processing, but machine adds surplus to be difficult for excessive, it is time-consuming to avoid machined steel to cut, and reduces production efficiency.As seen the axletree forging technology design is extremely important, must consider comprehensively, avoids producing forging defect.Present railway vehicle axle, axle journal, wheel seat and axle body concentricity are difficult to guarantee after finished product dust guard seat place machine adds the forging casting skin is arranged, cause product rejection.
Summary of the invention
The purpose of this utility model is to provide a kind of axle center concentricity that improves axle journal, wheel seat, axle body, and the railway vehicle axle that reduces axle journal, wheel seat forging size forges swage block.
Technical solution
The utility model comprises die cavity, the die cavity middle part is provided with the first circular arc type working face, the first working face two ends are symmetrically arranged with first step and second step respectively, are provided with the second circular arc type working face between first step and the second step, and the second step outside is provided with three-arc type working face.
The utility model difference with the prior art:
When existing axletree rough forging designs, axle journal and wheel seat are with a direct transition of slope step, enough for guaranteeing that finished product dust guard seat and axle journal step vertex position machine add surplus, must strengthen wheel seat length, cause that forging casting skin axletree scraps after avoiding machine to add; Wheel seat and axle body slope step are by swage block slope step free forming, and this moment, axle body contacted with the swage block working face, and wheel seat does not contact with swage block, make that wheel seat and axle body axiality are difficult to guarantee.
The utility model axle journal and wheel seat are with two slope steps and a platform transition, the gradient of two slope steps is determined according to the diameter drop between axle journal, wheel seat, axle body, the step gradient is identical between the gradient of the step that joins with axle journal and wheel seat and axle body, when forging axle body, wheel seat contacts with the swage block surface, the control axiality.
The utility model has the advantages that: can guarantee the axiality of axle journal, wheel seat and axle body, strengthen the allowance at each position virtually; Shorten wheel seat length, reduce rough forging weight, reduce the norm of material consumption.

The specific embodiment
The utility model die cavity 1 middle part is provided with the first circular arc type working face 2, the first circular arc working face, 2 two ends are symmetrically arranged with first step 3 and second step 5 respectively, be provided with the second circular arc type working face 4 between first step 3 and the second step 5, second step 5 outsides are provided with three-arc type working face 6.
The utility model axletree raw material square billet one end is clamped by manipulator, the other end becomes axletree to forge hair arbor wheel seat 9 back forging hair shaft neck 7 and axle bodies 10 at the first circular arc type working face, 2 place's chamfered edges of swage block die cavity 1, first step 3 at swage block die cavity 1, the second circular arc type working face 4 and second step 5 place's free forming axletrees forge hair axle the 3rd step 11, the 4th step 12 and dust guard seat 8, three-arc type working face 6 dead axles of swage block die cavity 1 forge hair arbor wheel seat, this moment, the axle center of axle journal 7 and wheel seat 9 was concentric, can reduce axletree and forge hair shaft neck diameter dimension and wheel seat length dimension; First step 3 place's free forming axletrees at swage block die cavity 1 forge hair axle the 5th step 13, forge hair axle the 3rd step 11 and the 5th step 13 gradients with highly identical, thereby make the second circular arc type working face, the 4 fixing hair arbor wheel seats 9 that forge of swage block die cavity 1, the axle center of wheel seat 9 and axle body 10 is concentric, has guaranteed that axle journal 7, wheel seat 9 and axle body 10 axle center are all concentric.Change a manipulator and clamp the forging hair shaft neck 7 that has been shaped, repeat aforesaid operations, forge the hair axle and all be shaped.
Because the railway vehicle axle belongs to part in enormous quantities, therefore efficiently become the problem of primary solution, also be the problem of most critical in process of production.For the manufacturer of a yearly productive capacity at 80,000 axletrees, cost efficiency and raising product percent of pass are particularly important.The utility model can fundamentally solve the various mass defects that axletree forges, and satisfies suitable machine-finish allowance requirement.
