Description
Technical field
The invention belongs to forging field, relate to a kind of rack rails punching sizing device and rack rails punching sizing technique.
Background technology
Rack rails, is again pin rail, is widely used in the industries such as coal machine, in use, a plurality of rack rails form one group of track after being connected on rack rails seat by bearing pin, one group or organize more track on the ground after, coal machine relies on the tooth portion of driving wheel and the engagement of the engaging tooth of rack rails to transmit motion walking.Rack rails production operation complicated condition is severe, can bear larger and inhomogeneous shock loading at work, and because machined is no longer carried out at other position except pin shaft hole, so at work the intensity of rack rails, dimensional accuracy and shape are had to higher requirement.
The technique of current domestic forging rack rails is: on die hammer or forging press, by card pressure, blocking and finish-forging, forge moulding, edge-cutting and hole-punching on press or hydraulic press, then by thermal recalibration operation, proofread and correct the distortion producing in edge-cutting and hole-punching process, residual overlap and burr that edge-cutting and hole-punching produces are repaired by follow-up polishing.
The weak point of this processing technology is: (1) rack rails is subject to the double action of trimming power and punching power in edge-cutting and hole-punching, because stressed excessive and unbalance stress causes each engaging tooth distortion, this distortion is along with the wearing and tearing meeting of mould is more and more serious, even by subsequent thermal, proofread and correct also and cannot repair, affect rack rails engagement capability, when serious, cause rack rails broken teeth in use procedure; (2) because edge-cutting and hole-punching composite die is without guiding, make to have dislocation between rack rails and punching pin, cause after edge-cutting and hole-punching hole dimension and shape in each to guarantee, and residual overlap and burr are larger, not only needing to spend the plenty of time goes polishing finishing, when serious, punching pin can injure engaging tooth body, causes whole rack rails to be scrapped; (3) because rack rails is that unfettered state and this operation are while edge-cutting and hole-punchings in edge-cutting and hole-punching mould, stressedly compared with conference, cause rack rails to occur flexural deformation, wearing and tearing along with mould, rack rails integral planar degree will be worse and worse, even by subsequent thermal, proofreaied and correct also and cannot be repaired, while causing installing or using, coal machine vibration is large.
Summary of the invention
The object of the present invention is to provide a kind of rack rails punching sizing device and rack rails punching sizing technique.By accurate guiding, to rack rails, apply pretightning force, thereby prevent that engaging tooth is out of shape in punch process; By mould, accurately locate rack rails, and give punching pin shaping-orientation, and making after punching that endoporus dimensional accuracy is better and shape is regular, residual overlap and burr are less, and adopt punching mode from top to bottom, making can not affect the engagement capability of rack rails because of the punching burr that punching pin wearing and tearing occur; By traditional edge-cutting and hole-punching operation and thermal recalibration operation are designed to trimming operation and punching sizing operation, disperse trimming power and punching power, reduce rack rails deflection, and adopt die reshaping further to repair the distortion of rack rails, guarantee rack rails integral planar degree.
