Described train wheel bridge is provided with a bending punching pin, and this bending punching pin is passed down through de-backing strap plate and stripper plate, sets in described stripper plate
Having to take off expects into son, is provided with lower mold and enters son in described lower bolster, and the bottom of described bending punching pin has a bending mouth, and bending mouth has
Having one for the bending vertical plane of bending product, the de-upper surface expecting to enter son into the lower surface of son and lower mold is parallel to each other, and de-
Expecting that lower surface and lower mold into son enter sub upper surface and be inclined-plane, product is positioned over lower mold and enters on son, upper module and lower module
After merging, de-lower surface and the lower mold expected into son enters sub upper surface and clamps product, after pressing, bears product under bending punching pin
Angle bending.
Further, the bending mouth of bending punching pin also has the cambered surface being connected on bending vertical plane upper end, the arc of bending mouth
Face is for the bending fillet of shaped article.
Further, the angle between described de-lower surface and the horizontal plane expecting son is 4 °, and lower mold enters the upper surface of son
And the angle between horizontal plane is also 4 °.
The beneficial effects of the utility model are: de-lower surface and the lower mold expected into son in this utility model enters the upper of son
Surface is inclined-plane, and de-lower surface and the lower mold expected into son enters sub upper surface and clamp product so that product is inclined, folding
Curved punching pin utilizes its bending mouth disposably product to be carried out bending, and owing to product is inclined, bending punching pin can be to product
Complete negative angle (less than 90 °) bending, owing to the product bending angle formed is slightly less than 90 °, such that it is able to compensate bending resilience, protect
Demonstrate,prove the qualified of 90 ° of bending angles of product.This utility model can carry out a negative angle bending and put in place product, compensates bending and returns
Bullet, it is ensured that product qualified, it is not necessary to frequently change mould parts, reduces repair a die frequency and production cost.

Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
As shown in Figures 1 to 4, a kind of product negative angle bending die tool, including upper module and lower module, upper module includes from upper
Upper bolster 1, upper padding plate 2, train wheel bridge 3, de-backing strap plate 4 and the stripper plate 5 set gradually under to, lower module includes depending on from top to bottom
The lower bolster 6 of secondary setting, lower bolster 7 and die shoe 8, described train wheel bridge 3 is provided with a bending punching pin 9, and this bending punching pin 9 is downward
Through de-backing strap plate 4 and stripper plate 5, described stripper plate 5 is provided with take off and expects, into son 10, described lower bolster 6 to be provided with lower mold and enters son
11, the bottom of described bending punching pin 9 has a bending mouth 901, and it is vertical for the bending of bending product that bending mouth 901 has one
Face, the de-upper surface expecting to enter son 11 into the lower surface of son 10 and lower mold is parallel to each other, and the de-lower surface expected into son 10 and lower mold
The upper surface entering son 11 is inclined-plane, and product 12 is positioned over lower mold and enters on son 11, upper module and lower die combination and after, de-expect into son
The lower surface of 10 and lower mold enter the upper surface of son 11 and clamp product 12, after 9 times pressures of bending punching pin, product 12 are carried out negative angle folding
Curved.
The bending mouth 901 of bending punching pin 9 also has the bending cambered surface being connected on bending vertical plane upper end, bending mouth 901
Bending cambered surface is for the bending fillet of shaped article.
Furtherly, the angle between de-lower surface and the horizontal plane expecting son 10 is 4 °, and lower mold enters the upper surface of son 11
And the angle between horizontal plane is also 4 °.
During work, as in figure 2 it is shown, upper module and lower mold combination die, de-expect that entering son 11 into son 10 and lower mold clamps product 12,
The de-upper surface expecting to enter son 11 into the lower surface of son 10 and lower mold is the inclined-plane that left end is high and right-hand member is low, thus is expected into son by de-
10 and lower mold to enter the products 12 clamped of son 11 inclined, as it is shown on figure 3, train wheel bridge 3 drives bending punching pin 9 to move down,
With de-, the bending mouth 901 of bending punching pin 9, during moving down, expects that entering son 11 into son 10 and lower mold coordinates, and completes product
The negative angle bending of 12.In the present embodiment, it is 86 ° of bendings.Wherein, the bending vertical plane of the bending mouth 901 of bending punching pin 9 with under
Mould enters the flanging of left surface (for facing directly) the cooperation shaped article 12 of son 11, the bending cambered surface shaped article 12 of bending mouth 901
Bending fillet.After bending and molding completes, upper module moves, carries out die sinking, after die sinking, the product after bending can be taken out.Due to
The flanging of product can produce a certain degree of bending resilience, and in the present embodiment, bending springback compensation angle is 4 °, then can ensure that
90 ° of bending angles of product qualified.This utility model can carry out a negative angle bending and put in place product, compensates bending and returns
Bullet, it is ensured that product qualified, it is not necessary to frequently change mould parts, reduces repair a die frequency and production cost.
