[0033] The top surface of work table 1 is symmetrically provided with two grooves. The two ends of the bottom of each lower die 14 are fixedly connected with protrusions, and the protrusions are slidably connected in the corresponding grooves. The lower die 14 is positioned on the top of the work table 1 through the cooperation of the grooves and the protrusions.

[0034] The side of each lower die 14 close to each other is provided with a plurality of semicircular stamping grooves, and the stamping grooves on the two lower dies 14 correspond one by one. The corresponding two stamping grooves cooperate to form a cylindrical stamping hole. The two stamping grooves cooperate to form a stamping hole to facilitate the stamping forming of the parts in the stamping hole.

[0035] The bottom of the upper die 4 is fixedly connected with a plurality of stamping rods, and the stamping rods correspond to the cylindrical stamping hole one by one. The stamping rod is movably arranged between the corresponding two stamping grooves. The parts are stamped into metal pipes through the cooperation of the stamping rod and the stamping hole.

[0036] The inside of work table 1 is provided with a collecting box 15, and the collecting box 15 is located directly below the plurality of stamping grooves. The top surface of work table 1 is provided with a blanking hole matched with the collecting box 15. The formed parts fall into the collecting box 15 through the blanking hole, and the parts are collected.

[0037] The top of one end of each lower die 14 away from each other is fixedly connected with a clamping groove plate 13.

[0038] The two ends of the upper die 4 are provided with driving members, and the driving members correspond to the clamping groove plates 13 one by one. When the upper die 4 moves upward, the driving members drive the corresponding clamping groove plates 13 to move, so that the two lower dies 14 move towards each other and move away from each other. The clamping groove plate 13 drives the lower die 14 to move, and when the two clamping groove plates 13 move towards each other, the two lower dies 14 are closed, and when the two clamping groove plates 13 move away from each other, the two lower dies 14 are opened.

[0039] The driving member comprises a rotating rod 5 vertically arranged and fixedly connected to the end of the upper die 4. An L-shaped connecting plate 7 is fixedly connected to the top of the workbench 1 at each clamping groove plate 13, and the rotating rod 5 slides through the top end of the corresponding connecting plate 7.

[0040] The bottom surface of the top end of each connecting plate 7 is rotationally connected with a rotating shaft 16, a one-way bearing 11 is fixedly sleeved on each rotating shaft 16, and a second gear 10 is fixedly sleeved on each one-way bearing 11. The bottom of the inner ring of each one-way bearing 11 is fixedly connected with a movable rod 12 which is slidingly connected in the corresponding clamping groove plate 13. When the one-way bearing 11 is locked, it will drive the movable rod 12 to rotate, and the rotation of the movable rod 12 on the clamping groove plate 13 will push the clamping groove plate 13 to move.

[0041] The bottom surface of the top end of each connecting plate 7 is rotationally connected with a first gear 8 which is engaged with the corresponding second gear 10. The rotating rod 5 slides through the corresponding first gear 8, so that the rotating rod 5 slides up and down in the inside of the first gear 8.

The outer surface of each rotating rod 5 is provided with a spiral limiting groove 6, and the clamping rod 9 is slidingly connected in the corresponding limiting groove 6. When the rotating rod 5 and the limiting groove 6 move up and down, the limiting groove 6 will drive the clamping rod 9 to rotate along the spiral direction of the limiting groove 6. The rotational directions of the two limiting grooves 6 are opposite, so that the rotational directions of the two first gears 8 are opposite, the rotational directions of the two second gears 10 are opposite, and the clamping groove plates 13 are driven to move in opposite directions.

[0043] Each connecting plate 7 is provided with a limiting assembly for limiting the rotating shaft 16.

[0044] The limiting assembly comprises a ratchet wheel 17 and a pawl 18. The ratchet wheel 17 is fixedly sleeved on the top end of the rotating shaft 16, and the pawl 18 is rotationally connected to the inside of the connecting plate 7.

[0045] The end of the pawl 18 is movably clamped between the two teeth of the ratchet wheel 17, and the pawl 18 is fixedly connected with the connecting plate 7 through a spring 19. In the initial state, the spring 19 pushes the pawl 18, so that the pawl 18 is clamped between the two teeth of the ratchet wheel 17, and the pawl 18 limits the rotating shaft 16 to rotate in one direction only.

[0046] Working principle:

[0047] When in use, the material to be formed is placed in the stamping hole between the two lower dies 14, and at this time the material corresponds to the stamping rod one by one.

[0048] The cylinder 3 is started, and the output end of the cylinder 3 pushes the upper die 4 to move downwards, and drives the stamping rod and the rotating rod 5 to move downwards. The rotating rod 5 moves downwards through the connecting plate 7 and the first gear 8, and drives the limiting groove 6 to move vertically downwards.

[0049] Since the limiting groove 6 is arranged in a spiral shape, the limiting groove 6 drives the clamping rod 9 to rotate in the spiral direction of the limiting groove 6 when moving, and drives the first gear 8 to rotate. The first gear 8 drives the second gear 10 to rotate, at this time, the one-way bearing 11 idles, and the inner ring of the one-way bearing 11 and the rotating shaft 16 cannot rotate through the cooperation of the ratchet wheel 17 and the pawl 18, and the movable rod 12 cannot rotate.

[0050] Until the stamping rod moves downwards into the corresponding stamping hole, the material is formed by stamping, and the processing of the automobile damping parts is realized.

[0051] The cylinder 3 drives the upper die 4, the rotating rod 5 and the stamping rod to move upwards, and the stamping rod gradually leaves the formed parts. At the same time, the limiting groove 6 drives the first gear 8 to rotate, and drives the second gear 10 to rotate, at this time, the one-way bearing 11 is locked, and drives the rotating shaft 16 and the movable rod 12 to rotate. The ratchet wheel 17 rotates, and pushes one end of the pawl 18, and the pawl 18 compresses the spring 19. At the same time, the spring 19 pushes the pawl 18, so that the pawl 18 is always clamped on the ratchet wheel 17. The ratchet wheel 17 and the pawl 18 are existing structures.

[0052] The rotation of the movable rod 12 in the inside of the clamping groove plate 13 pushes the clamping groove plate 13 to move, drives the lower die 14 to slide on the top of the workbench 1, and makes the two lower dies 14 move away from each other to open the mold. The formed parts fall into the collecting box 15.

[0053] The rotating rod 5 continues to move upwards, the movable rod 12 pushes the clamping groove plate 13 to make the two lower dies 14 close to each other, until the two lower dies 14 contact to close the mold.

[0054] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
