Abstract
The invention relates to a method for preventing white ground grinning of a flat touch type knife edge product. A pressing mechanism is designed on an upper mold, the pressing mechanism firstly presses a waste side region of the product, and the product is cut in a flat touch mode through a flat touch knife; or the internal structure of an upper mold forming mold is modified, the mold edge inner side corresponding to a product forming edge region is designed to be in an arc shape, the outer side of the formed product is inclined, an angle +R is designed between the outer side and the upper side, thus, the product side cutting position is tensioned and pressed in advance during product forming, and the product is cut in the flat touch mode through the flat touch knife; or a boss is designed at the position, corresponding to the waste side region, of a lower mold, the boss is higher than a sharp knife edge in the region where the boss is located, during flat touch cutting, the boss firstly makes contact with the waste side region of the product, and after the waste side region of the product is pressed, the shark knife edge conducts cutting. The method has the advantages that design is ingenious, the method is simple, the problem of cutting white ground grinning is solved in a product pre-pressing mode and a product outer side forming angle changing mode, and the quality of the product is improved.
Description
Technical field
The present invention relates to the field of product trimming, be specifically related to a kind of putting down and touch the method that formula edge of a knife product prevents from showing money or valuables one carries unintentionally.
Background technology
In manufacturing production, many plastic materials (metal or nonmetal) processing are to be processed into part (or semi-finished product) by pressing equipment, punching press is to utilize the mould being arranged on forcing press that material is applied pressure, it is made to produce to separate or plastic deformation, thus obtaining a kind of pressure processing method of required part. Diel is the requisite technological equipment of punching production, is technology-intensive product. The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture. The height of Mould design and manufacturing technical merit, is one of important symbol weighing a national product manufacture level height, decides the development ability of the quality of product, benefit and new product to a great extent. Adopt at present and flat touch the edge of a knife slitter edge district to product and cut, sharp knife mouth direct collision product, flat touch formula cutting and is more prone to the phenomenon that shows money or valuables one carries unintentionally.
Summary of the invention
In order to solve the problems referred to above, the present invention proposes and a kind of flat touches the method that formula edge of a knife product prevents from showing money or valuables one carries unintentionally, and designs ingenious, and method is simple, solves cutting by the mode compressed in advance and shows money or valuables one carries unintentionally problem.
In order to reach the problems referred to above, the present invention proposes techniques below scheme:
Put down and touch the method that formula edge of a knife product prevents from showing money or valuables one carries unintentionally, be characterized in particular in following steps:
1) designing a hold-down mechanism on upper mould, the slitter edge district of product is first compressed by hold-down mechanism, compresses in advance and is not less than 0.3mm, touches formula cutting again through the flat cutter that touches to product is flat;
2) or to upper die forming mould inside structural modification, it is designed to arc shape inside the die edge that formed product marginal zone is corresponding, after formed product, outside tilts in 15-20 �� and is designed to+R angle between outside and top, compress with regard to carrying out product trimming position in advance stretching during such formed product, touch formula cutting again through the flat cutter that touches to product is flat;
3) or counterdie design boss at slitter edge district correspondence position, boss exceeds the sharp knife mouth of region, and boss height is 0.5-0.7mm, and flat when touching cutting, boss first touches the slitter edge district of product, and after making the slitter edge district of product compress, sharp knife mouth is cutting;
4) method described in above-mentioned steps 1-3 or is simultaneously adopted to combine, first pass through when molding outside product and once draw inclined-plane, Shen and lead angle, form first time compression, product slitter edge district is carried out compressing stretching by the hold-down mechanism then through upper mould, forms secondary compression, before sharp-crested cutter cuts, the boss of counterdie design first touches the slitter edge district of product, forming third time to compress, sharp knife eloquence touches the slitter edge district of product afterwards, cuts.
1st) in step, hold-down mechanism can also individually designed be arranged on outside mould.
2nd) in step, after formed product, angle of inclination, outside the best is 15 degree.
It is an advantage of the invention that design is ingenious, method is simple, and outside the mode compressed in advance by product and product, profile angle shifts gears, and solves cutting and shows money or valuables one carries unintentionally problem, improves the quality of product.

Fig. 2 be the present invention step 3) described in schematic diagram.
In figure, 1, upper mould, 2, counterdie, 3, product zone, 4, slitter edge district, 5, the boss that increases of slitter edge district, 6, edge, product zone be+R angle, 15-20 �� of inclined-plane.
Detailed description of the invention
In order to reach the problems referred to above, the present invention proposes techniques below scheme:
Put down and touch the method that formula edge of a knife product prevents from showing money or valuables one carries unintentionally, be characterized in particular in following steps:
Designing a hold-down mechanism on upper mould, the slitter edge district of product is first compressed by hold-down mechanism, compresses in advance and is not less than 0.3mm, touches formula cutting again through the flat cutter that touches to product is flat; Hold-down mechanism can also individually designed be arranged on outside mould.
Such as accompanying drawing 1, or to upper die forming mould inside structural modification, it is designed to arc shape inside the die edge that formed product marginal zone is corresponding, after formed product, outside tilts in 15-20 �� and is designed to+R angle between outside and top, compress with regard to carrying out product trimming position in advance stretching during such formed product, touch formula cutting again through the flat cutter that touches to product is flat; After formed product, angle of inclination, outside the best is 15 degree.
Such as accompanying drawing 2, or counterdie designs boss at slitter edge district correspondence position, and boss exceeds the sharp knife mouth of region, and boss height is 0.5-0.7mm, and flat when touching cutting, boss first touches the slitter edge district of product, and after making the slitter edge district of product compress, sharp knife mouth is cutting;
Or adopt method described in above-mentioned steps 1-3 to combine simultaneously, first pass through when molding outside product and once draw inclined-plane, Shen and lead angle, form first time compression, product slitter edge district is carried out compressing stretching by the hold-down mechanism then through upper mould, forms secondary compression, before sharp-crested cutter cuts, the boss of counterdie design first touches the slitter edge district of product, forming third time to compress, sharp knife eloquence touches the slitter edge district of product afterwards, cuts.
