Abstract
A triple-action drawing die comprises an upper die, an upper blank holder arranged on the upper die, a lower die, a lower blank holder arranged on the lower die and a guide positioning structure. The key points include that the triple-action drawing die further comprises a nitrogen cylinder arranged between the upper die and the upper blank holder and a hydraulic ejection rod arranged below the lower blank holder, and the lower blanking holder forms a lifting structure with degree of freedom of lifting with the aid of the hydraulic ejection rod and the lower die. The triple-action drawing die has the technical advantages that the triple-action drawing die is simple in structure and convenient to use, difficulty in drawing forming is lowered, difficulty in debugging and production in the later period is reduced, different requirements of customers can be better met, production efficiency is improved, the defect of severe product cracking caused by a single-action drawing die is effectively overcome, and quality of products is improved.
Description
Technical field
The utility model belongs to field of automobile, relates to a kind of mould, particularly a kind of three moving drawing dies.
Background technology
In auto parts, have many product profile more complicated, the moulding degree of depth is dark, and profile exists darker positive and negative moulding position, for example back door inner panel.The moulding process substantially adopting now, still according to the trend of product, adopts conventional single draw mode to carry out moulding.This kind of mode moulding is more difficult, to later stage debugging, production, has caused great difficulty, and the inferior quality of product, also has to allow client change product-forming sometimes, can not meet well client's demand.
Summary of the invention
The purpose of this utility model is to adopt the moulding of single draw mode more difficult in order to solve, to later stage debugging, production, caused the technical problem of very big difficulty, in order to address this problem, we have designed a kind of three moving drawing dies, simple in structure, easy to use, reduced the difficulty of drawing and moulding, reduced the difficulty of later stage debugging, production, improved production efficiency, effectively overcome the serious defect ftractureing of product that single draw mould causes, improved the quality of product, can meet better client's different demands.
The concrete technical scheme that the utility model adopts is: a kind of three moving drawing dies, comprise patrix, be arranged on upper blank holder, counterdie on patrix, be arranged on lower blank holder, guiding-positioning structure on counterdie, key is: described drawing die also comprises the nitrogen cylinder being arranged between patrix and upper blank holder, the hydraulic mandril that is arranged on lower blank holder below, and lower blank holder forms the lifting structure with the lifting free degree by hydraulic mandril and counterdie.
The beneficial effects of the utility model are: nitrogen cylinder is set between patrix and upper blank holder, in lower blank holder bottom, hydraulic mandril is set, utilize nitrogen cylinder and hydraulic mandril can separately provide positive reverse-forming required pressure, make drawing and moulding more easily simple, reduced the difficulty of later stage debugging, production, can meet better client's different demands, improve production efficiency, can effectively overcome the serious defect ftractureing of product that single draw mould causes, improved product quality.In lower blank holder bottom, cushion block is set, can avoids hydraulic mandril directly to contact with lower blank holder and wearing and tearing that lower blank holder is caused.Upper die and lower die are by the cooperation guide-localization of guide pillars and bushes, and patrix and upper blank holder are by upper guide plate guide-localization, and counterdie and lower blank holder, by bottom guide guide-localization, make the accuracy of drawing and moulding higher, can improve the quality of product.Guide pin bushing on patrix can slow down the wearing and tearing of guide pillar in motion process, extends the service life of guide pillar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1 represents patrix, the upper blank holder of 2 representative, and 3 represent counterdie, the lower blank holder of 4 representatives, 5 represent nitrogen cylinder, 6 represent cushion block.
The specific embodiment
A kind of three moving drawing dies, comprise patrix 1, be arranged on upper blank holder 2, counterdie 3 on patrix 1, be arranged on lower blank holder 4, guiding-positioning structure on counterdie 3, key is: described drawing die also comprises the nitrogen cylinder 5 being arranged between patrix 1 and upper blank holder 2, the hydraulic mandril that is arranged on lower blank holder 4 belows, and lower blank holder 4 forms the lifting structure with the lifting free degree by hydraulic mandril and counterdie 3.
Described drawing die also comprises the cushion block 6 that is arranged on lower blank holder 4 bottoms, and lower blank holder 4 forms the lifting structure with the lifting free degree by cooperation and the counterdie 3 of hydraulic mandril and cushion block 6.
Described guiding-positioning structure comprises the guide pillar that is arranged on counterdie 3, be arranged on guide pin bushing on patrix 1, be arranged on upper guide plate on blank holder 2, be arranged on the bottom guide on lower blank holder 4, patrix 1 and counterdie 3 form guiding-positioning structure by the cooperation of guide pillars and bushes, patrix 1 and upper blank holder 2 form guiding-positioning structure by upper guide plate, and counterdie 3 and lower blank holder 4 form guiding-positioning structure by bottom guide.
The utility model is in the specific implementation: before starting working, the subsidiary upper blank holder 2 of patrix 1 is contained on lathe slide block, the subsidiary lower blank holder 4 of counterdie 3 is contained on the workbench of lathe, the bottom of hydraulic mandril is connected with lathe, and the top of hydraulic mandril contacts with cushion block 6, and by lower blank holder 4 jack-up.After starting working patrix 1 subsidiary under the effect of lathe slide block on blank holder 2 move downward together, until touch the lower blank holder 4 of jack-up on counterdie 3, now go up blank holder 2 and start to contact with lower blank holder 4.Then patrix 1 continues to move downward under the effect of lathe slide block, and upper blank holder 2 touches after lower blank holder 4, because the hydraulic top stick force under lower blank holder 4 is greater than the power of nitrogen cylinder 5 on upper blank holder 2, thereby lower blank holder 4 is motionless, upper blank holder 2 starts to shrink with respect to patrix 1, be that nitrogen cylinder 5 shrinks, until upper blank holder 2 bottom surfaces are retracted to patrix 1, contact, now complete reverse-forming work.Patrix 1 and 2 one-tenth of upper blank holders are as a whole, under the effect of lathe slide block, continue to move downward, and lower blank holder 4 starts to shrink, be that hydraulic mandril shrinks, until lower blank holder 4 bottom surfaces contact with counterdie 3, now complete positive shaping work, so far drawing end-of-job.Adopt three moving drawing forms, first first one-step forming, forms out the general shape of product, and reaches the effect of material stock, and finally moulding obtains final shaped article completely again.By the moulding of twice different directions, overcome the serious defect ftractureing of product that single action mould causes.
