Abstract

The utility model discloses a stamping die for forming by bending a negative angle. The stamping die for forming by bending the negative angle comprises an upper die and a lower die plate, wherein the upper die comprises an upper die base, a forming fixed block and a forming active block which are in detachable connection. The forming fixed block and the forming active block are placed close to each other relatively. A spring is arranged between the upper die base and the upper end of the forming fixed block. The upper end of the forming active block is fixedly connected with the upper die base. A chamfer face is arranged at a lower edge of one side of the forming active block which is close to the forming fixed block, and an oblique projection which is matched with the chamfer face is arranged at a lower edge of one side of the forming fixed block which is close to the forming active block. The stamping die for forming by bending the negative angle is simple in structure and low in production cost, and can improve element processing efficiency.

Description

A kind of diel for the bending negative angle formation
Technical field
The utility model relates to technical field of mold, particularly relates to a kind of diel for the bending negative angle formation.
Background technology
Diel is a kind of special process equipment that blank is processed into the part of various shapes in Cold Press Working, therefore is called again cold punching die.Be processed into for the right angle part in the diel of negative angle part, the most structure of present mould is comparatively complicated, as sets two molds and process, and complicated structure production cost is higher, also for processing brings difficulty, has reduced working (machining) efficiency simultaneously.
The utility model content
The purpose of this utility model just provide a kind of simple in structure, production cost is low, the diel that is used for the bending negative angle formation that can improve the part working (machining) efficiency.
In order to address the above problem, the utility model provides following technical scheme: a kind of diel for the bending negative angle formation, comprise the upper die and lower die plate, this patrix comprises upper bolster, shaping fixed block and the shaping movable block that removably connects, this shaping fixed block is relative with this shaping movable block is close to placement, be provided with spring between the upper end of this upper bolster and this shaping fixed block, the upper end of this shaping movable block is fixedly connected with this upper bolster; The lower edges and corners of one side of the shaping movable block of being close to the shaping fixed block offer a fillet surface, and the lower edges and corners of a side of the shaping fixed block of being close to the shaping movable block are provided with an oblique projection that is complementary with this fillet surface.
Preferably, the bottom of shaping movable block also is provided with a projection that is connected with fillet surface.
Preferably, this projection is the curved surface shape.
Adopt the beneficial effect of technique scheme to be: the shaping fixed block is relative with the shaping movable block is close to placement, and be close under the side of the shaping movable block of face both sides and shaping fixed block edges and corners and offer respectively fillet surface and oblique projection, during mold closing, the movable block that only needs to be shaped is downward, can finish to workpiece the processing of bending negative angle by the pressing of the oblique projection on the fillet surface on the shaping movable block and the shaping fixed block, this mould structure is simple, production cost is low, it is also comparatively convenient to process, and can improve the working (machining) efficiency of workpiece.In addition, the projection of a curve form that is connected with fillet surface is set in the bottom of shaping movable block also, can plays guide effect to workpiece to be processed, prevent that workpiece from coming off or misplace, impact processing.

The specific embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the diel that is used for the bending negative angle formation of the present embodiment comprises upper die and lower die plate 3, this patrix comprises upper bolster 1, shaping fixed block 5 and the shaping movable block 4 that removably connects, this shaping fixed block 5 and this shaping movable block 4 be relative is close to placement, be provided with spring 2 between the upper end of this upper bolster 1 and this shaping fixed block 5, the upper end of this shaping movable block 4 is fixedly connected with this upper bolster 1, pass through said structure, can finish the compacting work of workpiece, simple in structure and be easy to processing; The lower edges and corners of one side of the shaping movable block 4 of being close to shaping fixed block 5 offer a fillet surface 8, the lower edges and corners of one side of the shaping fixed block 5 of being close to shaping movable block 4 are provided with an oblique projection 9 that is complementary with this fillet surface 8, fillet surface 8 and the tiltedly coupling pressing of projection 9 can be used for orthogonal work piece 7 is carried out the processing of bending negative angle.
As shown in Figure 2, under the mold closing state, upper bolster 1 drives down motion of shaping movable block 4 by spring 2, shaping fixed block 5 is pushed down orthogonal work piece 7, by the shaping movable block 4 with fillet surface 8 and the coupling pressing with shaping fixed block 5 of oblique projection 9, the compacting of bending negative angle can be promptly finished at the position, right angle of orthogonal work piece 7.
As shown in Figure 3, the bottom of above-mentioned shaping movable block 4 also is provided with a projection 6 that is connected with fillet surface 8, and this projection 6 can play guide effect to workpiece to be processed, prevents that workpiece from coming off or misplace, impact processing.
As shown in Figure 3, above-mentioned projection 6 is the curved surface shape, and the design of curved surface can prevent that workpiece from being blocked by projection 6.
The below introduces operation principle of the present utility model:
Upper bolster 1 drives down motion of shaping movable block 4 by spring 2, the fixed block 5 that is shaped is simultaneously pushed down orthogonal work piece 7, by the shaping movable block 4 with fillet surface 8 and the coupling pressing with shaping fixed block 5 of oblique projection 9, the compacting of bending negative angle can be promptly finished at the position, right angle of orthogonal work piece 7, the guide effect of projection 6 can be played guide effect to orthogonal work piece 7, prevent that it from coming off or misplace, after compacting is finished, shaping movable block 4 is at first along with the drive of upper bolster 1 and spring 2 is back moved, continue along with upper bolster 1 back moves with postforming fixed block 5, paste at the workpiece of finishing on the shaping fixed block 5 and namely pass through to begin to carry out subsequently the processing of next workpiece under the Action of Gravity Field landing.
Adopt the beneficial effect of technique scheme to be: shaping fixed block 5 and shaping movable block 4 be relative is close to placement, and be close under the side of the shaping movable block 4 of face both sides and shaping fixed block 5 edges and corners and offer respectively fillet surface 8 and oblique projection 9, during mold closing, the movable block 4 that only needs to be shaped is downward, can finish to workpiece the processing of bending negative angle by the pressing of the fillet surface 8 on the shaping movable block 4 and the oblique projection 9 on the shaping fixed block 5, this mould structure is simple, production cost is low, it is also comparatively convenient to process, and can improve the working (machining) efficiency of workpiece.In addition, the projection 6 of a curve form that is connected with fillet surface 8 is set in the bottom of shaping movable block 4 also, can plays guide effect to workpiece to be processed, prevent that workpiece from coming off or misplace, impact processing.
The above only is preferred embodiment of the present utility model, should be pointed out that under the prerequisite that does not break away from the utility model creation design, and can also make some distortion and improvement, these all belong to protection domain of the present utility model.
