Abstract
The utility model discloses a cutting device, which comprises an upper die plate (1), a lower die plate (2) and a processing passage (7) arranged between the upper die plate (1) and the lower die plate (2). A first cutter (3) and a second cutter (4) are arrayed inside the upper die plate (1) along the direction of the processing passage (7); the second cutter (4) is positioned behind the first cutter (3), a limiting device is arranged right under the first cutter (3); a blanking passage (6) is arranged right under the second cutter (4); and the length of an edge of the first cutter (3) is smaller than that of a cut of a product. The cutting device has the advantages of high production yield and high product quality.
Description
Technical field
The utility model relates to cutter sweep, especially relates 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 accurate cutter sweep, workpiece accuracy can reach micron order, and repeatable accuracy height, specification unanimity, nest, boss etc. can punching press portal.In the global steel, have 60～70%, sheet material, wherein major part is to make finished product through punching press, the vehicle body of automobile, chassis, fuel tank, radiator fin, 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: the otch injustice, and the product height that scales off is different, the highest and minimum about 0.1mm, during less than ± 0.05mm, product must all detect the wasting manpower and material resources for the product requirement for height, and product percent of pass is low, causes product cost higher.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of production yield height, the cutter sweep of superior product quality.
For achieving the above object, the utility model provides a kind of cutter sweep, comprise cope match-plate pattern, lower bolster, be arranged at cope match-plate pattern and the middle processing channel of lower bolster, second cutting knife after being arranged with first cutting knife and being positioned at 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 the projection that is slidingly connected mutually in vertical direction of lower bolster 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 the utility model cutter sweep is: used cutting twice technology, cutting is earlier spacing with product for the first time, on product, get an impression, determined the 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. 2 is the main cutaway view of first cutting knife processing back product among the utility model cutter sweep embodiment;
Fig. 3 is the main cutaway view of second cutting knife processing back product among the utility model cutter sweep embodiment.
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 utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.Operation principle of the present utility model below is described in detail in detail.
Be the main cutaway view of the utility model cutter sweep embodiment as shown in Figure 1, a kind of cutter sweep, comprise cope match-plate pattern 1, lower bolster 2, be arranged at the processing channel 7 of cope match-plate pattern 1 and lower bolster 2 centres, second cutting knife 4 after being arranged with first cutting knife 3 and being positioned at first cutting knife 3 along processing channel 7 directions in the cope match-plate pattern 1, be provided with stopping means under first cutting knife 3, stopping means is 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 moves, protruding 9 whereabouts of determining, when strip 8 stop motions, projection 9 slides in lower bolster 2, after projection 9 slides into ad-hoc location, fixed part is fixed projection 9 and lower bolster 2, begins die-cutly, also is provided with and is 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 the utility model cutter sweep is as follows:
Carried the below that arrives first cutting knife, 3 edges of a knife by strip 8 through in type product after the punching press, projection 9 rises, the bottom surface of product contacts with projection 9 upper surfaces, be subjected to the support force of projection 9, first cutting knife 3 begins to cut, 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 as shown in Figure 2, cut finish after, strip 8 carries product and moves to second cutting knife, 4 belows, the part that 4 pairs of incision of product of second cutting knife do not rupture cuts, product is separated with strip 8, the position that second cutting knife 4 continues to move to lower bolster 2, product is pushed blanking channel 6 in the lower bolster 2, 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 is subjected to this power is very little, compares stability and the yield that has promoted product greatly with original technology, and the cutaway view of second cutting knife, 4 cutting back products as shown in Figure 3.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
