Abstract
The utility model relates to a reshaping forging die which comprises an upper die and a lower die. Empty concaves are arranged in the upper die and the lower die. A die cavity is formed by the empty concaves of the upper die and the lower die and matched with a die forging piece. A forging face is an adhering face of the upper die and the lower die. Cavity walls are arranged on the circumference of the empty concaves of the upper die and the lower die. The forging face is used as a benchmark, and a curved structure is arranged on the cavity walls, facing the die cavity, of the upper die and the lower die. The reshaping forging die can greatly reduce deformation of the die forging piece.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of shaping forging die.
Background technology
Forging part is aborning because the effect of prying and pulling and contraction, workpiece has distortion after the moulding, can not directly drop into next procedure processing, be head it off, usually adopt friction press or forging hammer to carry out shaping after forging, because these machineries are reciprocating type percussions, the shaping rebound amount is difficult to control, cause having the part workpiece can not satisfy specification requirement after the shaping, cause these parts to be scrapped.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of shaping forging die that greatly reduces deformation quantity.
For achieving the above object, the utility model provides following technical scheme: comprise upper die and lower die, described upper die and lower die are provided with recessed vacancy, the recessed vacancy of described upper die and lower die cooperates the suitable die cavity of formation and forging part, the binding face of described counterdie and patrix is forging and pressing face, be provided with the chamber wall around the recessed vacancy of described upper die and lower die, it is characterized in that: described upper die and lower die chamber wall is provided with warp architecture towards the edge of die cavity take forging and pressing face as benchmark.
By adopting technique scheme, upper die and lower die chamber wall is provided with warp architecture towards the edge of die cavity take forging and pressing face as benchmark, also stressed even when Forging Die is extruded, the Forging Die rebound amount is little, cause the forging part tolerance grade after institute's shaping high, shaping effect is good.
The utility model further is set to: described warp architecture is that radius is the circular arc of 0.5mm.
By adopting technique scheme, warp architecture can have various ways, and effect was better when to select warp architecture to be set to radius be the circular arc of 0.5mm, and rebound amount is less, and corresponding shaping effect can be controlled.
The utility model further is set to: described counterdie is provided with positioning recess along four ends of forging and pressing face, and described patrix is provided with the locating convex block suitable with the positioning recess shape size along forging and pressing face.
By adopting technique scheme, the locating convex block of patrix and the positioning recess of counterdie match and consist of location to upper/lower die, and the preferred rectangular recess of positioning recess has here fully guaranteed the alignment of die cavity, has namely strengthened the shaping effect of forging part.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the installation diagram in the utility model specific embodiment;
Fig. 2 is the part drawing of patrix in the utility model specific embodiment;
Fig. 3 is the part drawing of counterdie in the utility model specific embodiment.
The specific embodiment
Such as Fig. 1-shown in Figure 3, the utility model discloses a kind of shaping forging die, comprise patrix 1 and counterdie 2, described patrix 1 and counterdie 2 are respectively arranged with the recessed vacancy 11 of patrix and the recessed vacancy 21 of counterdie, the recessed vacancy 21 of the recessed vacancy 11 of patrix and counterdie cooperates the suitable die cavity of formation and forging part, patrix 1 and counterdie 2 binding faces be forging and pressing face, the recessed vacancy 11 of patrix and counterdie are provided with upper cavity wall 12 and lower mode cavity wall 22 around the recessed vacancy 21, upper cavity wall 12 and lower mode cavity wall 22 are provided with patrix warp architecture 121 and counterdie warp architecture 221 towards the edge of die cavity take forging and pressing face as benchmark, arrange like this, it is also stressed even when Forging Die is extruded, the Forging Die rebound amount is little, cause the forging part tolerance grade after institute's shaping high, shaping effect is good, patrix warp architecture 121 and counterdie warp architecture 221 are the circular arc of 0.5mm for radius, warp architecture can have various ways, effect was better when to select warp architecture to be set to radius be the circular arc of 0.5mm, rebound amount is less, corresponding shaping effect can be controlled, counterdie 2 is provided with positioning recess 23 along four ends of die forging pressure surface, patrix 1 is provided with the locating convex block 13 suitable with positioning recess 23 shape sizes along forging and pressing face, locating convex block 13 and positioning recess 23 match and consist of location to upper/lower die, here the preferred rectangular recess of positioning recess, fully guarantee the alignment of die cavity, namely strengthened the shaping effect of forging part.
