Description

Shallow U-shaped part bending die with flange
Technical field
The utility model relates to stamping technology field, relates in particular to a kind of shallow U-shaped part bending die with flange.
Background technology
As shown in Figure 3, be a kind of shallow U-shaped part with flange, raw material are sheet material, adopt bending die to shape.Common bending die has following problem man-hour adding, and because both sides and the flange of product is subject to force direction, after being shaped, product is easy to resilience, need to increase subsequent handling and correct, and has increased machining period, and production efficiency is low, and production cost is high.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, is difficult for resilience after providing a kind of product to be shaped, and corrects the shallow U-shaped part bending die with flange that production efficiency is high without subsequent handling.
The purpose of this utility model is achieved through the following technical solutions.The shallow shape part of U bending die with flange, comprise upper bolster, punch, die shoe, die, punch is connected to upper bolster below, the lower end of described punch is the convex shape of handstand, the top of die shoe connects die socket, die comprises left half die and right half die, left half die and right half die are rotatably connected on respectively left side and the right side of die socket, the left upper right side of half die and the upper left side of right half die are respectively equipped with L shaped breach, the below of die is provided with bullet apical organ, and left side and the right side of die socket upper surface are respectively equipped with location structure.During work, blank is placed on die, patrix is descending, left half die and right half die rotate under the effect of punch, because the upper right side of left half die and the upper left side of right half die are respectively equipped with L shaped breach, two L shaped breach form a U-shaped groove, and punch is compressed into U-shaped groove by the mid portion of blank, the both sides of blank at the upper side of left half die and right half die, form a U-shaped with flange respectively.Because punch is in punching course, the both sides of product and flange are all subject to a bending power, and when punch is pressed onto lowest order, the effect that product is shaped again, so product is difficult for resilience after being shaped.
As preferably, described bullet apical organ comprises push rod, sleeve, spring, and sleeve is embedded in die shoe, and spring is positioned at sleeve, and push rod is positioned at spring top, and the lower end of push rod is positioned at sleeve, and the upper end of push rod is positioned at the below of die.
As preferably, described location structure comprises location-plate, and location-plate is fixedly connected on die socket.
As preferably, the top of described upper bolster connects die shank.
The beneficial effects of the utility model are that product is difficult for resilience after being shaped, and without subsequent handling, corrects, and has improved production efficiency, has reduced production cost, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model counterdie.
Fig. 3 is the structural representation of product.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Fig. 1 to Fig. 2, shallow U-shaped part bending die with flange, by patrix and counterdie, formed, patrix comprises upper bolster 2, punch 3, die shank 1, die shank is fixedly connected on upper bolster top, and punch is fixedly connected on upper bolster below by straight pin and screw, and the lower end of punch is the convex shape of handstand.Counterdie comprises die shoe 7, die socket 6, die etc., the box body shape structure that die socket is rectangular, die socket is fixedly connected on die shoe upper surface by straight pin and screw, die comprises left half die 11 and right half die 5, the basic configuration of left half die and right half die is plate shape, the left left end of half die and the right-hand member of right half die are half-cylindrical, the left upper right side of half die and the upper left side of right half die are respectively equipped with L shaped breach, the left end of left half die is rotatably connected on the left side in die socket by rotating shaft, the right-hand member of right half die is rotatably connected on the right side in die socket by rotating shaft, the below of die is provided with bullet apical organ, play apical organ and comprise push rod 8, sleeve 9, spring 10, sleeve is embedded in die shoe, spring is positioned at sleeve, push rod is positioned at spring top, the lower end of push rod is positioned at sleeve, the upper end of push rod is positioned at the below of die, the left side of die socket upper surface distributes and is fixedly connected with a location-plate 4 with right side.When patrix is separated with counterdie, the left left end of half die and the right-hand member of right half die contact with die socket inner bottom surface, push rod is by the left end jack-up of the right-hand member of left half die and right half die, the right-hand member of left half die is inclined upwardly, the left end of right half die is inclined upwardly, and when patrix and counterdie pressing, left half die and right half die are horizontal level, lower surface and the pressing of die socket inner bottom surface of left half die and right half die, the L shaped breach on left half die and right half die forms U-shaped groove.During work, blank 12 is placed between two location-plates on die socket, patrix is descending, left half die and right half die rotate under the effect of punch, because the upper right side of left half die and the upper left side of right half die are respectively equipped with L shaped breach, two L shaped breach form a U-shaped groove, and punch is compressed into U-shaped groove by the mid portion of blank, the both sides of blank at the upper side of left half die and right half die, form a shallow U-shaped with flange respectively.Due in punch punching course, the both sides of product and flange are all subject to a bending power, and when punch is pressed onto lowest order, the effect that product is shaped again, so product is difficult for resilience after being shaped.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.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.
