Description
Technical field
The utility model relates to stamping technology field, relates in particular to the U-shaped part bending die of the different length of a kind of dual-side.
Background technology
As shown in Figure 5, it is the U-shaped part of the different length of a kind of dual-side, one side of U-shaped part goes out many compared with the opposite side length of side, if this U-shaped part adopts common bending die punching press, be the vertically effect design up and down of punch die, mould structure complexity, die cost is high, and the U-shaped part processing there will be short side wearing and tearing large, the problem of the easy resilience of long side.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, provides one can reduce short side wearing and tearing, avoids long side resilience, and simple in structure, die cost is low, U-shaped part bending die easy to use.
The purpose of this utility model is achieved through the following technical solutions.The U-shaped part bending die of the different length of dual-side, comprise upper bolster, punch, die shoe, die, punch is connected to upper bolster below, the left side, top of described die shoe is fixedly connected with bearing, die comprises movable matrix and fixing die, movable matrix is rotatably connected on bearing, the upper right side of movable matrix is provided with L shaped breach, the lower-left side of movable matrix connects the upper end of an extension spring, the lower end of extension spring is fixed on die shoe, fixing die is connected to right side, die shoe top, the left side of fixing die is an inclined-plane tilting to the right from lower-left, the upper side of movable matrix is provided with location-plate, the right side of fixing die is provided with location structure, the U-shaped that the Cheng Cong lower-left, lower end of described punch tilts to the right.When work, blank is placed on to die upside, and patrix is descending, and die compressed into by blank by punch, movable matrix rotates under the effect of punch, the inclined-plane in the L shaped breach of movable matrix and fixing die left side forms the U-shaped groove of an inclination, and U-shaped groove compressed into by blank by punch, and punch contacts with fixing die rigidity, product is shaped, patrix is up, and movable matrix resets under the effect of extension spring, and product is taken off from punch.Because the long side of product is subject to the downward active force of punch, play shaping operation, be difficult for resilience, it is shorter that U-shaped groove forms a side of the short side of product, and therefore the short side wearing and tearing of product are little; The part of long side, outside U-shaped groove and punch, can not interfere again, has reduced mould structure, and mould structure is become simple, and has reduced die cost.
As preferably, described bearing comprises symmetrical header board and the rear plate vertically arranging, between header board and rear plate, be provided with a brace table, the height of brace table is lower than the height of header board and rear plate, the right side of brace table is an inclined-plane having a down dip to the right from upper left, movable matrix is positioned at brace table upper side, is rotatably connected on header board and rear plate.
As preferably, described location structure comprises and is the L shaped support that stands upside down, and support is provided with location-plate.
As preferably, the below connection backing plate of described upper bolster, the below of backing plate is connected and fixed plate, and punch is connected on fixed head.
As preferably, the top of described upper bolster connects die shank.
The beneficial effects of the utility model are, can reduce short side wearing and tearing, avoid long side resilience, and simple in structure, die cost is low, easy to use.

Detailed description of the invention
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Figures 1 to 4, the U-shaped part bending die of the different length of dual-side, is made up of patrix and counterdie, and patrix comprises die shank 1, upper bolster 2, backing plate 3, fixed head 4, punch 13, die shank is fixedly connected on upper bolster upper side, the below of upper bolster arranges backing plate, and the below of backing plate arranges fixed head, and upper bolster, backing plate and fixed head are fixed together by straight pin and screw, punch is fixedly connected on fixed head by step, the U-shaped that the Cheng Cong lower-left, lower end of punch tilts to the right.Counterdie comprises die shoe 9, bearing 10, die etc., bearing is fixedly connected on the left side of die shoe upper side by screw, die comprises movable matrix 12 and fixing die 8, bearing comprises the symmetrical header board vertically arranging 103 and rear plate 101, between header board and rear plate, be provided with a brace table 102, the front side of brace table is connected with header board, the rear side of gripper shoe is connected with rear plate, the height of brace table is lower than the height of header board and rear plate, the right side of brace table is an inclined-plane having a down dip to the right from upper left, movable matrix is positioned at brace table upper side, the left side of brace table is protruded in the left side of movable matrix, movable matrix is rotatably connected on header board and rear plate by rotating shaft.The upper right side of movable matrix is provided with L shaped breach, and the lower-left side of movable matrix connects the upper end of extension spring 11, and the lower end of extension spring is fixed on die shoe.Fixing die is fixedly connected on die shoe upper surface right side, the left side of fixing die is an inclined-plane tilting to the right from lower-left, the upper side of movable matrix is fixedly connected with a location-plate, the right side of fixing die is provided with location structure, location structure comprises and is the L shaped support 7 of standing upside down, support is fixedly connected on fixing die by screw, and rack upper surface is fixedly connected with location-plate 6.When work, blank 5 is placed between two location-plates, and patrix is descending, and die compressed into by blank by punch, movable matrix rotates under the effect of punch, the inclined-plane in the L shaped breach of movable matrix and fixing die left side forms the U-shaped groove of an inclination, and U-shaped groove compressed into by blank by punch, and punch contacts with fixing die rigidity, product 14 is shaped, patrix is up, and movable matrix resets under the effect of extension spring, and product is taken off from punch.Because the long side of product is subject to the downward active force of punch, play shaping operation, be difficult for resilience, it is shorter that U-shaped groove forms a side of the short side of product, and therefore the short side wearing and tearing of product are little; The part of long side, outside U-shaped groove and punch, can not interfere again, has reduced mould structure, and mould structure is become simple, and has reduced die cost.
The above is preferably detailed description of the invention of the utility model, not limits practical range of the present utility model with this.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
