[0018] See also Figures 1 to 4 A continuously operable sliding bar sheet stamping die comprises a lower die 1 and an upper die 101, a gantry 102 is mounted on the lower die 1, a cylinder 103 is mounted on the gantry 102, an output end of the cylinder 103 is fixedly connected to the upper die 101, a fixed tube 401 is fixedly connected to the lower die 1, a movable rod 4 is slidably connected inside the fixed tube 401, an upper side of the movable rod 4 is fixedly connected to the upper die 101, and a stamping groove 40 is mounted on the lower die 1 7. A stamping plate 406 is installed inside the stamping groove 407, and a plurality of air suction holes 408 are opened on the stamping plate 406. Two sets of sliding tubes 403 are fixed and connected through the lower side of the fixed tube 401. An air suction pipe 409 is fixed and connected through one side of the sliding tube 403. The air suction pipe 409 is connected with the air suction hole 408. A piston 404 is slidably connected inside the sliding tube 403. A transmission rod 402 is fixedly connected between the piston 404 and the movable rod 4.

[0019] Among them, the workpiece is placed on the stamping groove 407 during stamping, and then the cylinder 103 drives the upper mold 101 to move downward. When the upper mold 101 drives the movable rod 4 to move downward, the transmission rod 402 will move downward, and when the transmission rod 402 moves downward, it will drive the piston 404 to move downward. When the piston 404 moves downward, it will cause a negative pressure environment to the suction pipe 409, so that the suction hole 408 has an adsorption force, which can adsorb the workpiece on the stamping groove 407 and fix the position of the workpiece on the stamping groove 407.

[0020] Preferably, the bottom sides of the two sets of sliding tubes 403 are fixed and connected with exhaust pipes 405 , and the exhaust pipes 405 pass through the lower mold 1 .

[0021] When the piston 404 moves downward, the gas inside the sliding tube 403 can be discharged through the exhaust pipe 405 to avoid excessive air accumulation inside the sliding tube 403 causing excessive pressure in the sliding tube 403 and thus damaging the sliding tube 403 .

[0022] Preferably, the sliding tube 403 and the air intake tube 409 are arranged in a "7" shape, and the intersection of the sliding tube 403 and the air intake tube 409 is fixedly connected to the limiting block 3.

[0023] When the piston 404 moves downward, a negative pressure environment is created on the suction pipe 409 , so that the suction hole 408 has an adsorption force, which can adsorb the workpiece on the stamping groove 407 and fix the position of the workpiece on the stamping groove 407 .

[0024] Furthermore, when the upper die 101 completes stamping and moves upward, the piston 404 moves upward to make the suction hole 408 lose its adsorption force, making it easier to remove the workpiece from the stamping groove 407.

[0025] As a further solution of the utility model: wherein, a plurality of buffer tubes 2 are fixedly connected to the lower mold 1, a buffer rod 201 is slidably connected inside the buffer tube 2, a movable plug 202 is fixedly connected to the bottom side of the buffer rod 201, and nitrogen is placed inside the buffer tube 2.

[0026] The buffer rod 201 is provided to buffer the downward movement of the upper mold 101, thereby preventing the workpiece from being damaged due to excessive pressure applied when the upper mold 101 moves downward.

[0027] Preferably, a pressure sensor 203 is installed on the inner bottom side of the buffer tube 2 , and a display 204 is installed on the outer side of the lower mold 1 , and the display 204 is electrically connected to the pressure sensor 203 .

[0028] When the movable plug 202 moves downward, nitrogen will apply pressure to the pressure sensor 203, and the pressure sensor 203 will transmit an electrical signal to the display 204, so that the specific value of the pressure applied by the cylinder 103 to the workpiece can be calculated through the pressure value on the pressure sensor 203.

[0029] Preferably, a symmetrical shock-absorbing block 301 is fixedly connected to the bottom side of the lower mold 1 , and the lower mold 1 is connected to the ground through the shock-absorbing block 301 .

[0030] The damping block 301 can prevent the exhaust pipe 405 from being blocked by the ground, so that the gas inside the sliding pipe 403 can be discharged through the exhaust pipe 405 .

[0031] Working principle: during stamping, the workpiece is placed on the stamping groove 407, and then the cylinder 103 drives the upper mold 101 to move downward. When the upper mold 101 drives the movable rod 4 to move downward, the transmission rod 402 will be driven downward by the transmission rod 402. When the transmission rod 402 moves downward, it will drive the piston 404 to move downward. When the piston 404 moves downward, it will cause a negative pressure environment for the suction pipe 409, so that the suction hole 408 has an adsorption force, which can adsorb the workpiece on the stamping groove 407 and fix the position of the workpiece on the stamping groove 407; when the upper mold 101 completes the stamping and moves upward, the piston 404 moves upward to make the suction hole 408 lose its adsorption force, so that the workpiece is easy to be taken out of the stamping groove 407; the above structure can fix the position of the workpiece on the stamping groove 407 through the arranged piston 404 and the suction pipe 409, and there is no need to fix the position of the workpiece through external components, which increases the storage area of ​​the stamping groove 407 and prevents the external components from being crushed.
