Abstract
The invention discloses a cutting device, which comprises an upper template (1), a lower template (2), and a processing channel (7) arranged between the upper template (1) and the lower template (2); a first cutter (3) and a second cutter (4) behind the first cutter are arranged in the upper template (1) along the processing channel (7); a limiting device is arranged below the first cutter (3); a charging channel (6) is arranged below the second cutter (4); and the length of the cutting edge of the first cutter (3) is smaller than that of the cut of a product. The cutting device has the advantages of high production yield and high product quality.
Description
Technical field
The present invention relates to a kind of cutter sweep, especially relate to a kind of cutter sweep that is used for diel.
Background technology
Stamping parts is compared with foundry goods, forging, has thin, even, light, strong characteristics.Punching press can be made the workpiece that has reinforcement, rib, fluctuating or flange that additive method is difficult to make, to improve its rigidity.Because adopt the precise cutting device, workpiece accuracy can reach micron order, and repeatable accuracy is high, specification is consistent, and nest, boss etc. can punching press portal.In the global steel; Have 60～70%, sheet material; Wherein major part is to process finished product through punching press, the vehicle body of automobile, chassis, fuel tank, radiator fin, and the iron core silicon steel sheet of the drum of boiler, the housing of container, motor, electrical equipment etc. all is a punch process; In the products such as instrument and meter, household electrical appliance, bicycle, office machinery, household utensil, a large amount of stamping parts are arranged also.
Existing drawing die for once cuts, and after the moulding, directly cuts the last time.Existing cutting mode has following shortcoming: otch is uneven, and the product height that scales off is different, the highest and minimum about 0.1mm; When requiring less than ± 0.05mm for product height, product must all detect the wasting manpower and material resources; And product percent of pass is low, causes product cost higher.
Summary of the invention
For solving the problems of the technologies described above, it is high to the invention provides a kind of production yield, the cutter sweep of superior product quality.
For realizing above-mentioned purpose; The invention provides a kind of cutter sweep; Comprise cope match-plate pattern, lower bolster, be arranged at the processing channel in the middle of cope match-plate pattern and the lower bolster, be arranged with first cutting knife and second cutting knife that is positioned at behind first cutting knife along the processing channel direction in the cope match-plate pattern, be provided with stopping means under first cutting knife; Be provided with blanking channel under second cutting knife, the knife edge length of first cutting knife is less than the length of the otch of product.
More excellent, stopping means for and lower bolster projection that is slidingly connected mutually in vertical direction and the fixed part that is used for fixing projection, can regulate the position of projection according to the length of product, make cutter sweep have more practicality.
More excellent, blanking channel is arranged in the lower bolster and vertically extends.
More excellent, also be provided with and be used to buoyant piece that strip is floated, the position of having stablized strip guarantees the efficient of cutting each time.
The beneficial effect of a kind of cutter sweep of the present invention is: used cutting twice technology; Cutting for the first time is earlier spacing with product, on product, gets an impression, has confirmed product height; Cutting for the second time; Product is separated with strip, the cutting accuracy of product is improved greatly, also promoted the yield of product.

Fig. 1 is the main cutaway view of a kind of cutter sweep embodiment of the present invention duty;
Fig. 2 is the main cutaway view of first cutting knife processing back product among a kind of cutter sweep embodiment of the present invention;
Fig. 3 is the main cutaway view of second cutting knife processing back product among a kind of cutter sweep embodiment of the present invention.
Among the figure
The 1-cope match-plate pattern, 2-lower bolster, 3-first cutting knife, 4-second cutting knife, 5-buoyant piece, 6-blanking channel, 7-processing channel, 8-strip, 9-projection.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.Operation principle of the present invention below is detailed.
Be depicted as the main cutaway view of a kind of cutter sweep embodiment of the present invention like accompanying drawing 1, a kind of cutter sweep comprises cope match-plate pattern 1, lower bolster 2, is arranged at the processing channel 7 in the middle of cope match-plate pattern 1 and the lower bolster 2; Under processing channel 7 directions are arranged with first cutting knife 3 and second cutting knife, 4, the first cutting knifes 3 that are positioned at behind first cutting knife 3, be provided with stopping means in the cope match-plate pattern 1, stopping means for and lower bolster 2 projection 9 that is slidingly connected mutually in vertical direction and the fixed part that is used for fixing projection 9; Can set the position of projection 9 according to the length of product; Make cutter sweep have more practicality, when strip 8 moved, projection 9 fell; When strip 8 stop motions; Projection 9 slides in lower bolster 2, and after projection 9 slided into ad-hoc location, fixed part was fixed projection 9 and lower bolster 2; Begin die-cutly, also be provided with and be used to buoyant piece 5 that strip 8 is floated.
Be provided with blanking channel 6 under second cutting knife 4, blanking channel 6 is arranged in the lower bolster 2 and vertically extends, and the product of cutting-out drops out from blanking channel 6.
The knife edge length of first cutting knife 3 when 3 pairs of otch of first cutting knife cut, can not make product and strip 8 separate fully less than the length of the otch of product.
The operation principle of the embodiment of a kind of cutter sweep of the present invention is following:
Carried the below that arrives first cutting knife, 3 edges of a knife through in type product after the punching press by strip 8, projection 9 rises, and the bottom surface of product contacts with projection 9 upper surfaces; Receive the support force of projection 9, first cutting knife 3 begins to cut, and the knife edge length of first cutting knife 3 is less than the length of the otch of product; When 3 pairs of otch of first cutting knife cut, product and strip 8 are separated fully, the cutaway view of first cutting knife, 3 cutting back products is shown in accompanying drawing 2; After cutting completion, strip 8 carries product and moves to second cutting knife, 4 belows, and the part that 4 pairs of incision of product of second cutting knife do not rupture cuts; Product is separated with strip 8, and the position that second cutting knife 4 continues to move to lower bolster 2 pushes the blanking channel 6 in the lower bolster 2 with product; Because passed through cutting of first cutting knife 3, so the otch of product only needs very little power just can separate, in making product and strip 8 separating process; Because the power that otch is applied is little; The amplitude that deforms so product receives this power is very little, has promoted the stability and the yield of product greatly with original compared with techniques, and the cutaway view of second cutting knife, 4 cutting back products is shown in accompanying drawing 3.
The above; Be merely the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
