Abstract
The utility model relates to a high boss fine blanking forming mould which has the technical scheme that a forming convex mould is fixedly installed in a convex mould fixing plate, and the tail of the forming convex mould is connected to a convex mould backing plate support arranged on the convex mould fixing plate; a forming concave mould is fixedly installed in a concave mould fixing plate, and the tail of the forming concave mould is connected to a concave mould backing plate support arranged on the concave mould fixing plate; a discharge sleeve is sleeved on the forming convex mould and is installed in a discharge plate, and the discharge plate is connected to the convex mould fixing plate; the forming convex mould is relative to the forming concave mould, and a boss punching hole is arranged in the center of the forming concave mould. The utility model is characterized in that a conical tip is arranged at the central position of the head of the forming convex mould. The utility model has simple and ingenious structure. Because the protruding conical tip is arranged at the end of the forming convex mould, the utility model can lower the forming force when the boss is in forming and can centralize the forming force within a small area to extrude materials to flow, thereby achieving the required height and also prolonging the service life of a forming part.
Description
Technical field
The utility model belongs to the Stamping Die Technology field, specifically relates to a kind of high boss essence that is used to process boss structure and is washed into the pattern tool.
Background technology
In the plates of automobile, smart effect towards boss is to utilize the boss on the part to replace rivet to rivet.Tradition such as be spirally connected with bolt, rivet and electric welding are fixing is connected technology to be compared, and the employing boss structure is riveted and can be increased substantially production efficiency, and techno-economic effect is very remarkable.Adopt in the boss riveting process, the height of boss directly has influence on the quality of riveting process.Boss forming of the prior art mainly relies on traditional extrusion forming process, promptly adopts the forming convax mould extruding, and the end of forming convax mould is generally planar structure, can't satisfy the requirement of high boss formed product.And the forming convax mould of this structure fractures under forming materials hardens violent situation easily, and the life-span of forming convax mould is shorter, and when producing in enormous quantities, the quality of product and output often can't satisfy the demands.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple and ingenious structure, high boss essence that production efficiency is high to be washed into the pattern tool, this mould can satisfy high boss moulding requirement, the forming part quality is good, and the service life of forming part and the service life of mould all prolong greatly.
The technical scheme that provides according to the utility model: a kind of high boss essence is washed into the pattern tool, comprises convex mould pad, punch retainer, stripper, die block, die backing plate, forming convax mould, discharging cover and molding concave die; Forming convax mould is fixedly mounted in the punch retainer, and the tail end of forming convax mould supports by the convex mould pad that is connected on the punch retainer; Molding concave die is fixedly mounted in the die block, and the tail end of molding concave die supports by the die backing plate that is connected on the punch retainer; Be set with the discharging cover on the described forming convax mould, the discharging cover is installed in the stripper, and stripper is connected on the punch retainer; Described forming convax mould is corresponding with molding concave die, and the center of molding concave die offers the boss punching, it is characterized in that: the head end center of described forming convax mould is provided with cone point.
As further improvement of the utility model, the angle of described cone point is 90 degree, and the height of cone point is 0.6mm.
As further improvement of the utility model, the elastic component that is used to provide stripping force is installed between described stripper and the punch retainer; Described elastic component adopts elastomeric material to make.
As further improvement of the utility model, offer the corresponding through hole of boss punching with the molding concave die center on the described die block, push rod upwards interts in through hole and boss punching, and the lower end of push rod is connected with push rod spring.
The utility model compared with prior art, advantage is: because the forming convax mould end is provided with outstanding cone point, can reduce forming force during the moulding boss, and can concentrate forming force that the material extruding is flowed in very little area, reach the requirement height, prolong the life-span of forming part simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged diagram of forming convax mould among Fig. 1.
The part drawing that Fig. 3 makes for the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly comprises convex mould pad 1, punch retainer 2, elastic component 3, stripper 4, die block 5, die backing plate 6, forming convax mould 7, discharging cover 8, molding concave die 9, push rod 10 and push rod spring 11.
As shown in Figure 1 and Figure 2, described forming convax mould 7 is fixedly mounted in the punch retainer 2, and the tail end of forming convax mould 7 supports by the convex mould pad 1 that is connected on the punch retainer 2, and convex mould pad 1 is used for dispersive pressure; Molding concave die 9 is fixedly mounted in the die block 5, and the tail end of molding concave die 9 supports by the die backing plate 6 that is connected on the punch retainer 5; Be set with discharging cover 8 on the described forming convax mould 7, discharging cover 8 is installed in the stripper 4, and stripper 4 is connected on the punch retainer 2; Described forming convax mould 7 is corresponding with molding concave die 9, the center of molding concave die 9 offers boss punching 13, the head end center of forming convax mould 7 is provided with cone point 14, and the angle of this cone point 14 preferably is set to 90 degree, and the height of cone point 14 preferably is set to 0.6mm.
As shown in Figure 1, the elastic component 3 that is used to provide stripping force is installed between described stripper 4 and the punch retainer 2; The described elastic component 3 preferred elastomeric materials that adopt are made.Offer boss punching 13 corresponding through holes 12 on the described die block 6 with molding concave die 7 centers, push rod 10 upwards interts in through hole 12 and boss punching 13, the lower end of push rod 10 is connected with push rod spring 11, and the part of the active force that push rod 10 relies on push rod spring 11 after with moulding unloads.
When the utility model is used for essence and is washed into the type boss, forming convax mould 7 at first contact material be the cone point 14 at top, cone point 14 is concentrated the stamping-out forming force on very little area, product material is clamp-oned in the boss punching 13 on the molding concave die 9, obtains the product (shown in Figure 3) of high boss; Because the forming convax mould 7 stressed sections of having are poor, can prolong greatly its service life simultaneously.
