The traction rope 62 is wound around the winding shaft 61, and the other end of the traction rope 62 is fixed to the clamping rod 41. A first bevel gear 64 is provided on the winding shaft 61.

[0042] like Figure 6 An adjusting hole 411 is provided on the clamp rod 41, and the clamp rod 41 is rotatably connected to a rotating shaft 43. An adjusting slot 431 is provided on the rotating shaft 43. The clamp block 42 is located in the adjusting hole 411, and one end of the clamp block 42 is located in the adjusting slot 431 and is slidably connected to the rotating shaft 43. A connecting seat 44 is provided on the clamp block 42. A plurality of connecting holes 432 are provided on the inner wall of the sliding slot 211 along its length direction. The connecting seat 44 is aligned with one of the connecting holes 432 and is bolted to the rotating shaft 43.

[0043] The rotating shaft 43 is slidably connected with a rotating sleeve 65 . One end of the rotating shaft 43 extends into the rotating sleeve 65 and is slidably connected with the rotating sleeve 65 . A second bevel gear 66 is provided at one end of the rotating sleeve 65 away from the clamping rod 41 . The second bevel gear 66 meshes with the first bevel gear 64 .

[0044] When hot stamping the automobile decorative strips, as the hydraulic cylinder 12 drives the heater 2 to descend, the heater 2 drives the sliding plate 31 to descend, the sliding plate 31 drives the buffer rod 34 to descend, the buffer rod 34 squeezes the spring 53, the spring 53 pushes the rack 51 to move downward, the rack 51 drives the rotating gear 54 to rotate, the rotating gear 54 drives the moving rod 52 to move toward the buffer rod 34 through the connecting piece 55, and the moving rod 52 drives the connecting rod 56 to move. The connecting rod 56 drives the clamping rod 41 to slide on the sliding rod 4, and the two clamping rods 41 approach each other. During the movement, the clamping rod 41 pulls the traction rope 62, and the traction rope 62 drives the winding shaft 61 to rotate. The winding shaft 61 drives the first bevel gear 64 to rotate, and the first bevel gear 64 drives the second bevel gear 66 to rotate. The second bevel gear 66 drives the rotating sleeve 65 to rotate, and the rotating sleeve 65 drives the rotating shaft 43 to rotate. At the same time, when the two clamping rods 41 approach each other, the rotating shaft 43 moves in the direction of extending out of the rotating sleeve 65, thereby realizing that the clamping block 42 clamps the automobile decorative strip.

[0045] When the rack 51 contacts the limit plate 13, the clamping block 42 completely extends out of the workbench 1 and clamps the car decorative strip. As the heater 2 continues to descend, the buffer rod 34 squeezes the spring 53, so that the clamping block 42 can continue to descend after clamping the car decorative strip.

[0046] After the hot stamping of the automobile decorative strip is completed, the hydraulic cylinder 12 drives the heater 2 to rise, and the heater 2 drives the sliding plate 31 to rise. The sliding plate 31 is mobilized on the buffer rod 34, and the buffer rod 34 is lifted alone first. When the spring 53 returns to its natural state, the buffer rod 34 pulls the rack 51 to lift together. The rack 51 drives the rotating gear 54 to rotate during the lifting process, and the rotating gear 54 drives the moving rod 52 to approach the sliding rod 4. The moving rod 52 drives the connecting rod 56 to move, and the connecting rod 56 drives the clamping rod 41 to move. The two clamping rods 41 gradually move away from each other, and the torsion spring 63 gradually returns to its natural state to drive the winding shaft 61 to wind the traction rope 62. The winding shaft 61 drives the first bevel gear 64 to rotate, and the second bevel gear 66 drives the rotating sleeve 65 to rotate. The clamping block 42 gradually retracts into the workbench 1 while moving away from the automobile decorative strip, thereby completing the resetting of the clamping block 42.

[0047] like Figure 3 The connecting member 55 includes a sleeve 551 and a guide rod 552 . The guide rod 552 is disposed on the rotating gear 54 . The sleeve 551 is rotatably connected to one side of the moving rod 52 , and the guide rod 552 passes through the sleeve 551 .

[0048] When the rotating gear 54 rotates, the rotating gear 54 drives the guide rod 552 to swing, the guide rod 552 drives the sleeve to rotate, and the sleeve drives the moving rod 52 to move.

[0049] The implementation principle of the embodiment of the present application is as follows: when the heater 2 descends, the heater 2 drives the sliding plate 31 to descend, the sliding plate 31 drives the buffer rod 34 to descend, the buffer rod 34 drives the rack 51 to descend, the rotating gear 54 drives the guide rod 552 to rotate, the guide rod 552 drives the sleeve 551 to move and rotate, the sleeve 551 drives the moving rod 52 to move, the moving rod 52 drives the two clamping rods 41 to approach each other through the connecting rod 56, when the clamping rod 41 moves, the winding shaft 61 drives the first bevel gear 64 to rotate, the first bevel gear 64 drives The second bevel gear 66 rotates, and the second bevel gear 66 drives the rotating shaft 43 to rotate. The rotating shaft 43 drives the clamping block 42 to approach and gradually flip out of the workbench 1. When the rack 51 abuts against the limiting plate 13, the clamping block 42 clamps the end of the automobile decorative strip. At this time, the heater 2 continues to descend, and the buffer rod 34 gradually extends into the buffer groove 511. The upper tire membrane 22 gradually presses the automobile device strip for hot stamping, thereby realizing the longitudinal limitation of the automobile decorative strip during the hot stamping process, realizing the positioning of the automobile decorative strip, and reducing the deviation of the automobile decorative strip during hot stamping.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
