Rack rails, is again pin rail, is widely used in the industries such as coal machine, in use, multiple 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 at work larger and inhomogeneous shock loading, and because machined is no longer carried out at other position except pin shaft hole, so the intensity to rack rails, dimensional accuracy and shape have higher requirement at work.The rack rails of current domestic forging, to forge moulding by card pressure, blocking and finish-forging on die hammer or forging press, edge-cutting and hole-punching on press or hydraulic press, then proofread and correct by thermal recalibration operation 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.Therefore, develop a kind of rack rails punching sizing device, apply pretightning force by accurate guiding to rack rails, thereby prevent that engaging tooth is out of shape in punch process; Accurately locate rack rails by mould, and give punching pin shaping-orientation, make after punching that endoporus dimensional accuracy is better and shape is regular, residual overlap and burr are less, reduce rack rails deflection, and adopt die reshaping further to repair the distortion of rack rails, ensure rack rails integral planar degree.Such rack rails punching sizing device, will be subject to user and welcome.
Utility model content
The purpose of this utility model is to provide a kind of rack rails punching sizing device, applies pretightning force by accurate guiding to rack rails, thereby prevents that engaging tooth is out of shape in punch process; Accurately locate rack rails by mould, and give punching pin shaping-orientation, make after punching that endoporus dimensional accuracy is better and shape is regular, residual overlap and burr are less, reduce rack rails deflection, and adopt die reshaping further to repair the distortion of rack rails, ensure rack rails integral planar degree.
In order to realize foregoing invention object, the utility model by the following technical solutions: a kind of rack rails punching sizing device, comprising: shaping assembly, punching assembly, ejection assembly; Wherein, punching assembly is fastened on the cope match-plate pattern of shaping assembly, and ejection assembly is placed in the lower bolster and counterdie of shaping assembly.
Described shaping assembly, comprise: lower bolster, counterdie, guide pillar, positioning key, pressing plate, cope match-plate pattern, patrix, centre are held and hit piece, left and right is held and hit piece, backstay, lower bolster is connected with the table top on equipment, counterdie is fixed on lower bolster by lower positioning key and pressing plate, guide pillar is arranged on counterdie, cope match-plate pattern is connected with the slide block on equipment, patrix is connected to above cope match-plate pattern by upper guide post and upper guide post seat, left and right is held and is hit piece and centre and hold and hit piece and be fastened on cope match-plate pattern, and backstay is arranged between lower bolster and cope match-plate pattern.
Described punching assembly, comprising: punching pin, fastening base, punch fixing plate, nitrogen spring, upper guide post, upper guide post seat, voussoir; Punching pin is fastened on fastening base, and fastening base is fixed on cope match-plate pattern by punch fixing plate, and nitrogen spring is fastened on cope match-plate pattern, and upper guide post is arranged on cope match-plate pattern after being connected with upper guide post seat, and voussoir is placed in counterdie.
Described ejection assembly, comprising: backing-out punch and batten, and backing-out punch is placed in counterdie, and batten is placed in lower bolster.
Owing to adopting above-described technical scheme, the utility model can reach following beneficial effect: this device applies pretightning force by accurate guiding to rack rails, thereby prevents that engaging tooth is out of shape in punch process; Accurately locate rack rails by mould, and give punching pin shaping-orientation, make after punching that endoporus dimensional accuracy is better and shape is regular, residual overlap and burr are less, reduce rack rails deflection, this device can effectively prevent that rack rails is out of shape in punch process, has ensured the overall quality of rack rails.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, as shown in Fig. 2 ~ 3: a kind of rack rails punching sizing device, comprising: shaping assembly, punching assembly, ejection assembly.
Described shaping assembly, comprise: lower bolster 1, counterdie 2, guide pillar 3, positioning key 4, pressing plate 8, cope match-plate pattern 9, patrix 10, centre is held and is hit piece 11, left and right is held and is hit piece 15, backstay 17, lower bolster 1 is connected with the table top C on equipment with key by tommyhead bolt, counterdie 2 is fixed on lower bolster 1 by lower positioning key 4 and pressing plate 8, guide pillar 3 is arranged on counterdie 2 by interference fit, cope match-plate pattern 9 is connected with the slide block D on equipment with key by tommyhead bolt, patrix 10 is connected to above cope match-plate pattern 9 by upper guide post 18 and upper guide post seat 19, left and right hold hit piece 15 and centre hold hit piece 11 by screw fastening on cope match-plate pattern 9, backstay 17 is placed in the locating hole of lower bolster 1 for supporting cope match-plate pattern 9, be convenient to this device to be arranged on equipment, after installing, backstay 17 need to remove.
Described punching assembly, comprise: punching pin 13, fastening base 12, punch fixing plate 14, nitrogen spring 16, upper guide post 18, upper guide post seat 19, voussoir 7, punching pin 13 by screw fastening on fastening base 12, fastening base 12 is fixed on cope match-plate pattern 9 by punch fixing plate 14, nitrogen spring 16 by screw fastening on cope match-plate pattern 9, be used for providing pretightning force and stripping force, voussoir 7 is placed in counterdie 2, skids off for the gross weight that makes to wash out.
