Abstract
The invention discloses a composite die for crankshaft forging pieces. The composite die for the crankshaft forging pieces is characterized by being composed of an upper template (1), a male die (2), a female die (3), a female die base plate (4), a left supporting vertical board (5a), a right supporting vertical board (5b), a knockout plate (6), a left knockout plate guide column (7a), a right knockout plate guide column (7b), belleville springs (8), a lower template (9), a correction knockout (10), left and right guide columns (12) and left and right guide sleeves (13). The correction knockout (10) is fixedly installed on the upper end face of the knockout plate (6) and is also a lower correction die, the crankshaft forging pieces are corrected between the male die (2) and the correction knockout (10) after trimming is finished, and trimming and correction of a crankshaft are finished in one stroke.
Description
affiliated field
What the present invention relates to is forcing press composite die, for once completing trimming, correction to the crankshaft forging after die forging.And effectively can ensure the length dimension of forging, linearity, calibration requirement.
Background technology
Traditional crankshaft forging trimming, trimming process be by die forging after forging in shaving die, complete trimming operation, and then complete correction work with special Correction Die.
Prior art crankshaft forging shaving die adopts Tiebar structure, when forcing press top shoe 1 is in upper dead center position, pull bar drives liftout plate and the backing-out punch on it to be also in extreme higher position by U-shaped supporting plate, band overlap crankshaft forging is placed on backing-out punch, when forcing press top shoe 1 moves down, the cope match-plate pattern be arranged on top shoe moves down with the punch on it, U-shaped supporting plate simultaneously, liftout plate, backing-out punch and on forging by deadweight also move down, after crankshaft forging contacts with lower cavity die, backing-out punch and forging are thrown off and are continued to move down, until the contacts baseplate of liftout plate and forcing press, top shoe 1 moves down arrival BBC, the punch be arranged on cope match-plate pattern contacts with crankshaft forging and promotes forging and carry out trimming on lower cavity die cutting edge, crankshaft forging drops on backing-out punch.Then forcing press top shoe is up when moving to upper dead center position, takes out forging.Again crankshaft forging is put in another set of Correction Die and forging is corrected.
Prior art uses one set of die to carry out trimming to forging, and then forging is put into another set of mould and correct.
The shortcoming deficiency of prior art is; Backing-out punch seat is on liftout plate, and crankshaft forging is when punch contacts trimming with die, and backing-out punch does not contact with forging, and crankshaft forging is carried out in trimming process solid without pulling on counterdie, is in free state, causes trimming to be out of shape and increases the weight of.
Although again corrected the forging that trimming distortion occurs by follow-up another set of mould, length dimension, the presentation quality of forging can not ensure very well.Use two molds, twice pressure production process, production cost is higher.
Summary of the invention
The object of the invention is to improve for above-mentioned the deficiencies in the prior art, a kind of crankshaft forging composite die is provided, realize in the one stroke of forcing press, complete forging trimming, correction, to reduce crankshaft forging trimming distortion, improve length dimension, linearity, the indexing accuracy of forging.
The present invention is by cope match-plate pattern 1, and punch 2, die 3, die backing plate 4, left and right supporting vertical plate 5a, 5b, liftout plate 6, left and right liftout plate guide pillar 7a, 7b, butterfly spring 8, lower bolster 9, correction backing-out punch 10, left and right guide pillar 12, left and right guide pin bushing 13 are formed.
Cope match-plate pattern 1 is arranged on forcing press top shoe, punch 2 is installed and is connected on cope match-plate pattern 1 lower surface, left and right supporting vertical plate 5a, 5b is fixedly mounted on lower bolster 9 upper surface, die backing plate 4 is fixedly mounted on left and right supporting vertical plate 5a, on 5b upper surface, die 3 is arranged in the installation groove that die backing plate 4 upper surface is offered, left and right liftout plate guide pillar 7a, 7b is fixedly connected with and is arranged on lower bolster 9 upper surface, at left and right liftout plate guide pillar 7a, 7b is provided with butterfly spring 8, slide opening 61 is offered at the two ends, left and right of liftout plate 6, respectively with left and right liftout plate guide pillar 7a, the sliding connection of 7b upper end, at left and right liftout plate guide pillar 7a, the upper end of 7b is provided with positioning compression nut 71a, 71b, at left and right supporting vertical plate 5a, groove 51a is offered in the middle part of 5b, 51b, can pass to make liftout plate 6 and move up and down, correcting backing-out punch 10 is fixedly mounted on liftout plate 6 upper surface, left and right guide pillar 12 is fixedly mounted on the left and right sides of lower bolster 9 upper surface respectively, with be fixedly connected with the left and right guide pin bushing 13 be arranged on cope match-plate pattern 1 lower surface and coordinate, carry out guiding to cope match-plate pattern 1 with lower bolster 9 to be connected.
Left and right of the present invention guide pillar 12 and left and right guide pin bushing 13 coordinate and move up and down guiding to cope match-plate pattern 1, and namely correct backing-out punch 10 is backing-out punch, and be also correct counterdie, the upper surface shape correcting backing-out punch 10 is consistent with crankshaft forging finish-forging counterdie shape simultaneously.
Cope match-plate pattern 1 corrects the upper end of backing-out punch 10 higher than die 3 cutting edge when upper dead center position.When starting working, band gross weight crankshaft forging A is placed on and corrects on backing-out punch 10, the descending punch 2 of cope match-plate pattern 1 first contacts with the forging A be placed on backing-out punch, promote forging A descending together with correction backing-out punch 10 and liftout plate 6, complete gross weight A1 trimming as forging A and die 3 edge contacts; It is descending together with correction backing-out punch 10 and liftout plate 6 that punch 2 continues to promote crankshaft forging A, when cope match-plate pattern 1 arrives bottom dead centre, the pressure that butterfly spring 8 acts on liftout plate 6 reaches maximum, crankshaft forging A after trimming is at punch 2 and correct between backing-out punch 10 and complete correction work, ensure crankshaft forging A be the die cavity consistent with its shape pull solid fraction state under complete trimming, correction.
When cope match-plate pattern 1 is up, butterfly spring 8 elastic force promotes liftout plate 6 and corrects backing-out punch 10 up, when after the up disengaging crankshaft forging A of punch 2, corrects backing-out punch 10 and is released from die 3 cutting edge by crankshaft forging A.
Forging of the present invention completes trimming, the correction of bent axle in one stroke of press, save one special correcting process, and ensure that crankshaft forging is in trimming process, be in and pull solid fraction state preferably, reduce crankshaft forging trimming distortion, the length dimension of crankshaft forging, linearity, calibration are effectively guaranteed, and improve precision.
Be consistent because correcting the upper end cavity shape of backing-out punch 10 with the shape of counterdie during crankshaft forging A die forging, crankshaft forging A only need put into correction backing-out punch 10 upper end, without the need to doing careful adjustment, simple to operate, safe and reliable.
