Detailed description of the invention
With reference to shown in accompanying drawing, die cutting die the utility model being used for sheet material further illustrates.
Embodiment: with reference to Fig. 1, this product 0 is that the existing die cutting die for sheet material is produced, this product 0 is the composite plate of a kind of steel plate 1 and aluminium sheet 2, after the die cutting die of prior art is die-cut, the disconnected tangent plane of this product 0 creates euphotic belt 1b and tear-strap 1c, and there is the larger angle 1a and burr band 1d that collapses, this thickness collapsed on the width of angle 1a is more than or equal to 30% of this product 0 its thickness (T), and the angle between this disconnected tangent plane and side of composite plate is less than 90 degree.The defect that the section of so this product 0 exists is just larger, and do not meet the requirement of standardized product 0, it is second-rate.
With reference to Fig. 2, this product 0 is that the die cutting die for sheet material of the present utility model is produced, this product 0 is the composite plate of a kind of steel plate 1 and aluminium sheet 2, after die cutting die of the present utility model is die-cut, the disconnected tangent plane of this product 0 does not produce euphotic belt 1b and tear-strap 1c, and there is the less angle 1a and burr band 1d that collapses, this thickness collapsed on the width of angle 1a is less than 30% of this product 0 its thickness (T), this thickness collapsed on the depth direction of angle 1a is less than 4% of this product 0 its thickness (T), and the angle between this disconnected tangent plane and side of composite plate is between 90 degree to 91 degree.The defect that the section of so this product 0 exists is just smaller, and meet the requirement of standardized product 0, its quality is higher.
A kind of die cutting die for sheet material of the utility model, comprise upper die component and lower mold assemblies, upper die component comprises upper bolster 7, fixed head 3 is provided with below upper bolster 7, stripper 4 is provided with below fixed head 3, drift fixed block 9 is also provided with below upper bolster 7, drift fixed block 9 is positioned at the side of fixed head 3 and stripper 4, drift fixed block 9 is provided with drift 8, lower mold assemblies comprises die shoe 12, die backing plate 6 is provided with above die shoe 12, concave template 5 and punching and blanking die 11 is provided with above die backing plate 6, punching and blanking die 11 is positioned at the side near drift 8, the blade of drift 8 is single sided taper and arranges downwards to the lopsidedness near product 0, the die-cut waste material 10 got off can directly be taken away by drift 8, blade clearance is provided with between the medial surface of drift 8 and the lateral surface of punching and blanking die 11.The drift 8 of this mould utilizes single side punching, be beneficial to the distance (C) of the blade clearance between adjustment and the section of product 0, can the distance of this blade clearance (C) be adjusted to as between 0.15mm to 0.25mm, when the thinner thickness of product 0, the distance (C) of blade clearance selects 0.15, and the effect of such stamping-out is better; When the thickness of product 0 is thicker, the distance (C) of blade clearance selects 0.25, and the effect of such stamping-out is better, and preferably 0.2mm, such stamping-out product 0 quality is out higher.
