Abstract

The utility model discloses a bending die with stable dimensions, comprising an upper die seat, an upper base plate, an upper back plate, an upper clamping plate, a slider seat, a slider, a positioning plate, a lower die plate, a warping plate, a stripper plate, a lower base plate, a lower die seat, a top plate, rubber and a lower supporting plate. The upper base plate, the upper back plate and the upper clamping plate are sequentially fixed on the upper die seat; the upper end of the slider seat is fixed on the upper clamping plate, and the sliders which are symmetrically arranged are connected in two side inclined chutes of the slider seat in a sliding mode; and the lower die plate is fixed on the lower base plate which is fixed on the lower die seat, the positioning plate is arranged at two outer sides of the lower die plate, the warping plate is articulated with the inner side of the lower die plate, and the top plate and the rubber are arranged between the lower die seat and the lower supporting plate. The bending die with stable dimensions can bend metal sheets through the matching of the sliders and the warping plate, and avoids the defect of squeezed deformation of the sheets caused by the matching bending of the traditional convex mold and concave die; and the formed product has good dimension stability and uniform wall thickness.

Description

The bending die of dimensionally stable

Technical field

The utility model relates to a kind of cold punching die, particularly relates to a kind of bending die of dimensionally stable.

Background technology

Cold punching die is to be installed on the forcing press, and the plate in being placed on is at room temperature applied deformation force, makes it produce distortion, thereby obtains definite shape, the special specific purpose tool of the product parts of size and performance.Because punch is littler than the thickness of sheet metal with the gap of die, sheet material can influence the cold stamping performance of products because of the extruding attenuation in BENDING PROCESS.

The utility model content

The purpose of the utility model is to provide that a kind of deflection is little, the bending die of dimensionally stable.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The utility model is a kind of bending die of dimensionally stable, and it comprises upper bolster, upper padding plate, goes up backboard, train wheel bridge, take-up housing, slide block, location-plate, lower bolster, seesaw, stripper plate, lower bolster, die shoe, top board, rubber, bottom plate; Described upper padding plate, go up backboard, train wheel bridge successively fixedly on the upper bolster, the upper end of take-up housing is fixed on the train wheel bridge, and symmetrically arranged slide block slips in take-up housing two skew back chutes; Described lower bolster is fixed on the lower bolster; Lower bolster is fixed on the die shoe; Location-plate is installed in two outsides of lower bolster; Seesaw is hinged on the lower bolster inboard, and top board and rubber are installed between die shoe and the bottom plate, and cover top surface and the push rod that is arranged in the lower bolster, die shoe lean.

Described seesaw has two, and symmetry is hinged on two relative inboards of lower bolster respectively.

After adopting such scheme; Because the utility model cooperates through slide block and seesaw; Sheet metal is carried out bending, avoided commonly using the defective that sheet material that punch and die engage flex caused is extruded distortion, the finished size good stability of moulding, wall thickness are even.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Description of drawings

Fig. 1 is the front view of the utility model.

The specific embodiment

As shown in Figure 1; The utility model is a kind of bending die of dimensionally stable, and it comprises upper bolster 1, upper padding plate 2, goes up backboard 3, train wheel bridge 4, take-up housing 5, slide block 6, location-plate 7, lower bolster 8, seesaw 9, stripper plate 10, lower bolster 11, die shoe 12, top board 13, rubber 14, bottom plate 15.

Described upper padding plate 2, go up backboard 3, train wheel bridge 4 successively fixedly on the upper bolster 1, the upper end of take-up housing 5 is fixed on the train wheel bridge 4, and symmetrically arranged slide block 6 slips in 5 liang of skew back chutes 51 of take-up housing.

Described lower bolster 8 is fixed on the lower bolster 11, and lower bolster 11 is fixed on the die shoe 12, and location-plate 7 is installed in two outsides of lower bolster 8.Described seesaw 9 has two, and symmetry is hinged on two relative inboards of lower bolster 8 respectively.

Be connected through lower cushion block 16 between described die shoe 12 and the bottom plate 15, between forms an accommodation space.Described top board 13 and rubber 14 are installed in the accommodation space between die shoe 12 and the bottom plate 15, and top board 13 upper surfaces lean with the push rod 17 that is arranged in lower bolster 11, the die shoe 12.

The operation principle of the utility model:

During work, take-up housing 5 is descending, and when slide block 6 touched stripper plate 10, under the guiding of 5 liang of skew back chutes 51 of take-up housing, slide block 6 moved to both sides, and simultaneously, seesaw 9 cooperates the bending of realization to sheet metal 100 around its pin joint swing and with slide block 6.

The emphasis of the utility model just is: adopt seesaw as bool.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
