Abstract
A multi-hole type die case is provided with a body (1), wherein the body (1) is in a cylinder shape, and a material leaking hole (2) is arranged on the lower end of the body (1). The multi-hole type die case is characterized in that at least two cutting edge through holes (3) are arranged on the upper end of the body (1), wherein the cutting edge through holes (3) are vertically arranged, the upper ends of the cutting edge through holes (3) are communicated till the upper end face of the body (1) in a penetrating mode, the lower ends of the cutting edge through holes (3) are communicated with the material leaking hole (2), and an anti-rotating structure is arranged on the outer side wall of the body (1). According to the multi-hole type die case, at least two cutting edge through holes (3) are arranged on the upper end of the body (1) of a concave die case, when two or multiple adjacent holes in an automobile cover part are punched, punching hole processes are reduced, and therefore manual labor, financial resources and material resources are saved, and producing speed of finished products is accelerated. Besides, the multi-hole type die case has the advantages of being clever in conception, simple in structure, easy to transform, low in transforming cost, and the like.
Description
Technical field
The utility model belongs to technical field of mold, specifically, and the particularly die case in the car panel die.
Background technology
At present, the hole in the automobile panel is more, and the aperture less in these holes, and corresponding car panel die need to be produced these holes.Along with the development of automobile industry and the raising of automobile sales volume, time constantly increase of the pressure of car panel die in order to guarantee the life-span of drift in die life and the mould, has produced the punching concave die cover.Original standard concave die sleeve is cylindric, its upper end only has a cutting edge through hole, the lower end of this cutting edge through hole communicates with corresponding material spilling hole, and the shape of cross section of the shape of cross section of described material spilling hole and cutting edge through hole adapts, and the cross section of material spilling hole is larger than the cross section of cutting edge through hole.
Adopt the standard concave die sleeve of said structure, only have a cutting edge through hole on the die case, can only with a drift correspondence.But exist in the automobile panel and two or more adjacent holes also usually occur, and pitch-row is nearer, and then assembly space is not enough with the existing standard die case, causes the plate can only the operation break-down punching, not only make the increase of punching operation, waste of manpower, financial resources and material resources, and slowed down the speed that finished product.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of porous type die case that can reduce the punching operation.
The technical solution of the utility model is as follows: a kind of porous type die case, has body (1), this body (1) is cylindric, be provided with material spilling hole (2) in the lower end of body (1), it is characterized in that: be provided with at least two cutting edge through holes (3) in the upper end of body (1), described cutting edge through hole (3) is vertically arranged, the upper end of cutting edge through hole (3) connects to the upper surface of body (1), the lower end of cutting edge through hole (3) communicates with material spilling hole (2), is provided with anti-rotation structure at the lateral wall of described body (1).
The utility model arranges at least two cutting edge through holes by the upper end at the die case body, and the lower end of cutting edge through hole is communicated with material spilling hole, in the punching press automobile panel during two or more adjacent hole, use this porous type die case, can remedy the defective of using existing standard die case assembly space deficiency, thereby reduce the punching operation, save manpower, financial resources and material resources, and accelerate the speed of finished product.
As a kind of prioritization scheme, described anti-rotation structure is the spline breach (4) that is arranged on body (1) lateral wall, this spline breach (4) semicircular in shape, and described spline breach (4) is with the upper and lower end face perforation of body (1).Like this with semicircular spline breach as anti-rotation structure, during assembling, only need processing the other half round cut corresponding with the spline breach with the part that matches in die case body side, insert again the spline pin and can prevent that die case from rotating, have area occupied little, be convenient to the advantage that the cutting edge through hole distributes.
As another kind of prioritization scheme, described anti-rotation structure is that body (1) lateral wall is cut the flat aspect of spline (5) that flat becomes, the flat aspect of described spline (5) extends to the lower surface from the upper surface of body (1), not only make processing convenient with the flat aspect of spline as anti-rotation structure, and the mould overall structure is simpler after the assembling.
The upper end of described body (1) is provided with three cutting edge through holes (3), wherein first cutting edge through hole (3) is circular, second is strip, the 3rd is rectangle, in body upper end three variform cutting edge through holes are set like this, make die case can be used for locating hole, hole clipping and via hole on the simultaneously punching press automobile panel.
All cutting edge through holes (3) are corresponding same material spilling hole (2) all, this material spilling hole (2) is the cylinder hole of vertically arranging, the shape of cross section of its shape of cross section and body (1) adapts, and makes all sides of body (1) lower end material spilling hole (2) form sidewall (1a).Like this that all cutting edge through holes is all corresponding with a large material spilling hole, waste material is discharged more smooth and easy, and simplified the processing technology of material spilling hole, more save production cost.
The height of described body (1) is advisable with 20-25mm, and the height of cutting edge through hole (3) is advisable with 6-8mm, and the thickness of sidewall (1a) is advisable with 3-7mm.When body height less than the height of 20mm, cutting edge through hole less than 6mm, sidewall thickness during less than 3mm, the insufficient strength of die case is easily damaged; When body height during greater than 7mm, not only there is no need but also waste material greater than 8mm, sidewall thickness greater than 25mm, cutting edge via height.
Beneficial effect: the utility model arranges at least two cutting edge through holes by the upper end at the die case body, during two or more adjacent hole in the punching press automobile panel, the punching operation is reduced, save manpower, financial resources and material resources, and accelerate the speed of finished product, have be skillfully constructed, simple in structure, transform easily and the characteristics such as improvement cost is low.
