Abstract
The utility model discloses a stamping and stretching die. The stamping and stretching die comprises an upper die (1) and a lower die (2). A kerf portion, a stretching portion, a punching portion and a blanking portion are sequentially arranged on the upper die (1) and the lower die (2). The stamping and stretching die is characterized in that the kerf portion is divided into a first kerf portion (3) and a second kerf portion (4), and positions of kerf connection points formed on the first kerf portion (3) and the positions of kerf connection points formed on the second kerf portion (4) are staggered. A shaping portion (5) is arranged between the stretching portion and the punching portion, and the shaping portion (5) comprises a shaping punch (6) and a shaping die insert (7), wherein the shaping punch (6) is arranged on the upper die (1), and the shaping die insert (7) is arranged on a position, matching with the shaping punch (6), of the lower die (2). An ejection block (8) is arranged below the shaping die insert (7). The stamping and stretching die can prevent metal plates from being torn in the process of stretching, and products with high size accuracy can be obtained.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of punching stretch mould.
Background technology
In the Punching Process of sheet material, need to use punching stretch mould, utilize concave, convex punching press on sheet material (and stretching) of inserting on upper and lower mould required shape, traditional punching stretch mould is when stretching, if the deflection stretching large (stretching highly larger), likely occur the phenomenon that sheet metal is torn, the precision of the workpiece that this processing mode obtains is simultaneously relatively low.Therefore need now a kind of Novel punching drawing die that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind ofly can prevent that in drawing process, panel beating is torn, and can obtain the punching stretch mould of higher dimensional precision product.
Technical solution of the present utility model is: a kind of punching stretch mould, comprise patrix 1 and counterdie 2, on patrix 1 and counterdie 2, be disposed with cut out portion, stretched portion, punching part and blanking part, it is characterized in that: described cut out portion is divided into the first cut out portion 3 and the second cut out portion 4, and stagger mutually in the formed otch tie point position of the otch tie point position that the first cut out portion 3 is formed and the second cut out portion 4, and be provided with shaping unit 5 between stretched portion and punching part, shaping unit 5 comprises the shaping drift 6 being arranged on patrix 1, the position matching with shaping drift 6 on counterdie 2 is provided with correcting die and inserts 7, at correcting die, insert below 7 and be also provided with ejection block 8.
Compared with the existing technology, tool has the following advantages the utility model:
The punching stretch mould of this kind of version, it is simple in structure, design ingenious, rationally distributed, it is for traditional punching stretch mould when the stretching step that stretches highly larger, and the problem of tearing easily appears in panel beating, before the stretching structure of traditional punching stretch mould, designed two notch features, and the otch that these two notch features cut out on sheet material staggers mutually, can prevent that panel beating is at stretching step Fracture; Simultaneously it is also provided with shaping unit between stretched portion and punching part, and the existence of this shaping unit can allow to machine the internal diameter size precision of rear workpiece higher.The manufacture craft of this punching stretch mould is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.As shown in Figure 1: a kind of punching stretch mould, comprise patrix 1 and counterdie 2, on patrix 1 and counterdie 2, be disposed with cut out portion, stretched portion, punching part and blanking part, above-mentioned cut out portion is comprised of the first cut out portion 3 and the second cut out portion 4, and stagger mutually in the otch tie point position that the otch tie point position that the first cut out portion 3 forms on panel beating and the second cut out portion 4 form on panel beating, be workpiece after cut out portion, can be through twice incision operation; Do like this and can guarantee that panel beating can not tear in the process stretching;
Between stretched portion and punching part, be provided with shaping unit 5, this shaping unit 5 comprises the shaping drift 6 being arranged on patrix 1, the position matching with shaping drift 6 on counterdie 2 is provided with correcting die and inserts 7, and correcting die insert 7 below be also provided with ejection block 8; The effect of shaping unit 5 is that the appearance and size of goods after stretched operation is adjusted, and makes it more accurate, thereby is applicable to the product that precision is higher.
