The technical solution of the present invention is: a bending mold based on a spring swinging convex mode, including a punching rod, a mold handle, a die, a discharge block, a movable punch, a positioning plate, a pendulum block, a guide plate, a lower mold base, and an upper pad Plate, fastening screw, spring, lower backing plate, screw rod, positioning pin, rotating shaft, the T-shaped end of the die handle is processed with a through hole, which is connected with the die with screws, and the punching rod runs through the die handle and the die. The other end is processed with threads for connecting the unloading block. The punching rod, die handle, die and unloading block together form the upper die; the movable punch runs through the guide plate and the lower die base, and the other end is connected to the upper pad by the fastening screw. The two positioning plates are respectively placed on the left and right sides of the lower mold base, the two pendulum blocks are connected with the movable punch through the rotating shaft, and are respectively placed on both sides of the movable punch, and the two positioning pins are placed on the upper surface of the movable punch. The guide plate is fixed on the lower mold base through screw connection, 4 springs are placed between the lower backing plate and the upper backing plate, and 4 screws run through the lower backing plate, springs, and the upper backing plate is connected with the lower mold base. The movable punch, positioning plate, Pendulum block, guide plate, lower mold base, upper backing plate, fastening screw, spring, lower backing plate, screw rod, locating pin, rotating shaft form lower mold together.

The discharge block is in the shape of a cuboid, and the upper end surface is processed with a threaded hole; the lower backing plate and the upper backing plate are processed with a shallow hole for spring positioning; the shape of the two pendulum blocks is eight-shaped, and the lower end is a circular arc transition , easy to slide on the guide plate.

The bending mold based on the spring swing convex mode described in the present invention has simple structure, convenient use, low design and manufacturing costs, and can be formed at one time shape parts.

Detailed ways

As shown in Figure 1, the bending mold based on the spring swing convex mode includes a punching rod 1, a mold handle 2, a die 3, a discharge block 4, a movable punch 5, a positioning plate 6, a pendulum block 7, and a guide plate 8 , lower mold base 9, upper backing plate 10, fastening screw 11, spring 12, lower backing plate 13, screw rod 14, positioning pin 15, rotating shaft 16, the T-shaped end of mold handle 2 is processed with through holes, and it is screwed Connected with the die 3, the punching rod 1 runs through the die handle 2 and the die 3, and the other end is processed with threads for connecting the unloading block 4, the punching rod 1, the die handle 2, the die 3, and the unloading block 4 Together form the upper mold; the movable punch 5 runs through the guide plate 8 and the lower mold base 9, and the other end is connected with the upper backing plate 10 through the fastening screw 11, and the two positioning plates 6 are respectively placed on the left and right sides of the lower mold base 9, 2 A pendulum block 7 is connected with the movable punch 5 through a rotating shaft 16, and is respectively placed on both sides of the movable punch 5, and two positioning pins 15 are placed on the upper end surface of the movable punch 5, and the guide plate 8 is fixed on the lower mold base 9 through screw connection, Four springs 12 are placed between the lower backing plate 13 and the upper backing plate 10, four screw rods 14 run through the lower backing plate 13, the springs 12, the upper backing plate 10 is connected with the lower mold base 9, the movable punch 5, the positioning plate 6, Pendulum block 7, guide plate 8, lower mold base 9, last backing plate 10, fastening screw 11, spring 12, backing plate 13, screw rod 14, positioning pin 15, rotating shaft 16 form lower die jointly.

The discharge block 4 is in the shape of a cuboid, and the upper end surface is processed with a threaded hole; the lower backing plate 13 and the upper backing plate 10 are processed with a shallow hole, which is used for the positioning of the spring 12; The lower end is in a circular arc transition, which is convenient for sliding on the guide plate 8.

The bending mold based on the spring swing convex mode, the upper mold moves downward under the drive of the stamping machine, the sheet is first bent into a U shape by the elastic force under the action of the die 3 and the movable punch 5, and the upper mold continues to go down, The movable punch 5 compresses the spring 12 and moves downward, and the workpiece is bent and shaped by the pendulum block 7 and the guide plate 8 . When the upper mold returns, the punching rod 1 pushes the workpiece out of the die 3 through the discharge block 4 under the action of the punching beam of the press, and completes the whole bending process.
