Abstract
The utility model relates to the field of stamping dies, in particular to a trimming and scrap cutting die structure comprising an upper die (1), an upper die trimming blade (3), an upper die trimming blade (4) with a scrap cutter, a lower die scrap cutter (8), a lower die, a transitional blade (2) and a drive device. The transitional blade (2) is mounted between the upper die trimming blade (3) and the upper die trimming blade (4) with the scrape cutter, and the drive device for driving the transitional blade (2) is mounted on the upper die (1). According to the design, burr left at the position with height difference of the blades is avoided, trimming quality of parts is improved greatly, scrap cutoff quality is improved since the scrap is cut off structurally in a pressing state, and quantity of burr is controlled.
Description
Technical field
The utility model belongs to diel field, relates in particular to a kind of trimming and cut the mould structure of waste material.
Background technology
In the stamping Die Design of body of a motor car part, design for edger is set up and follows 333 principles always at the cloth of edge-trimming cutter piece, waste knife piece, and the depth of tooth penetration of edge-trimming cutter is that the space of dodging of 3mm, patrix edge-trimming cutter and counterdie waste knife is that the depth of tooth penetration of 3mm, waste knife is 3mm.This will determine on mould structure that the edge-trimming cutter of patrix and the edge-trimming cutter piece of patrix band waste knife have the difference in height of 3mm at interface.
The defect of this kind of scheme existence is as follows.
1, because the edge-trimming cutter piece of patrix and the edge-trimming cutter piece of patrix band waste knife exist difference in height taking interface, wedging when two edge-trimming cutters are different when can causing trimming, exist the priority on same limit to cut off, can have the mass defects such as interface burr and smear metal in incision.
2, the cut-out of waste material is carried out under non-binder state, therefore can produce a large amount of smear metals and the large defect of waste material burr.Smear metal meeting affects surface quality and the die life of product.。
Summary of the invention
The purpose of this utility model is to provide a kind of trimming that is intended to address the above problem to cut the mould structure of waste material.
The utility model is to realize like this, the mould structure of waste material is cut in a kind of trimming, comprise edge-trimming cutter piece and the counterdie waste knife of upper die and lower die, patrix edge-trimming cutter piece, patrix band waste knife, be also included in the transition cutter piece of installing between described patrix edge-trimming cutter piece and the edge-trimming cutter piece of patrix band waste knife and the drive unit on described patrix that is arranged on that drives described transition cutter piece.
The edge-trimming cutter piece of patrix, transition cutter piece under duty, belong to fairing with the edge-trimming cutter piece of waste knife and seamlessly transit, do not have the difference in height of the 3mm that dodges counterdie waste knife.Broken through trimming structure 333 principles of originally always following, realized 303 motion structure, patrix is realized and cut off waste material under binder state by moving up and down of transition cutter piece.
Due to the poor cancellation of edge-trimming cutter interblock transition altitude, make the border of part realize cut-out simultaneously, solve the burr that original meeting exists at the poor place of cutter tile height, the trimming quality of part is promoted significantly, realize waste material from structure cuts off under binder state, the quality that waste material cuts off is improved, and burr is controlled.Under the state of binder, realize and cutting off, effectively control the generation of smear metal when cut-out, more effectively protect product quality and die life.Concentrate owing to cutting off effective iron filings of having controlled simultaneously the problem of damaging mould binder surface and surface quality of workpieces in cutter piece transition region.
Further technical scheme of the present utility model is: described transition cutter piece one end is concordant with the edge-trimming cutter piece of patrix band waste knife with patrix edge-trimming cutter piece.Ensure trimming quality.
Further technical scheme of the present utility model is: described transition cutter piece agrees with mutually with counterdie waste knife.Ensure that part waste material cuts off under binder state, make to cut off quality and improve, reduced the probability with waste material, the automatic landing of more favourable and waste material.
Further technical scheme of the present utility model is: described drive unit adopts nitrogen spring.Improve stamping parts quality, ensure stamping parts steady quality, raise labour productivity, reduce product cost.Long service life, safety, reliable, easy to installation and maintenance, simple.Ensure continuation at described patrix descending in described in transition cutter piece move upward, waste material is kept to certain pressure simultaneously.
Further technical scheme of the present utility model is: be increased in the transition cutter piece guide plate that install in described transition cutter piece outside, described transition cutter piece guide plate is fixedly connected with described patrix.Stressed larger due in diel work engineering, transition cutter piece access times can produce skew after too much.After increasing transition cutter piece guide plate, make transition cutter piece can not produce displacement, increase the quality of stamping products.
The beneficial effects of the utility model are: in the middle of edge-trimming cutter piece and the edge-trimming cutter piece with waste knife, increased transition cutter piece; The edge-trimming cutter piece of patrix, transition cutter piece under duty, belong to fairing with the edge-trimming cutter piece of waste knife and seamlessly transit, do not save as the difference in height of the 3mm that dodges counterdie waste knife.Broken through trimming structure 333 principles of originally always following, realized 303 motion structure, patrix is realized and cut off waste material under binder state by moving up and down of transition cutter piece.Due to the poor cancellation of edge-trimming cutter interblock transition altitude, make the border of part realize cut-out simultaneously, solve the burr that original meeting exists at the poor place of cutter tile height, the trimming quality of part is promoted significantly realize waste material from structure to cut off under binder state, the quality that waste material cuts off is improved, and burr is controlled.Under the state of binder, realize and cutting off, effectively control the generation of smear metal when cut-out, more effectively protect product quality and die life.Cut-out simultaneously has effectively been controlled iron filings and has been concentrated and the problem of damage mould binder surface and surface quality of workpieces in cutter piece transition region.Part waste material cuts off under binder state, makes to cut off quality and improves, and has reduced the probability with waste material, the automatic landing of more favourable and waste material.Equipment is simple and reliable, and accuracy is high, reduces manually, raises the efficiency.
