The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0017] Example: See Figure 1 - Figure 5 The utility model provides a technical solution: a punch feeder tensioning device, comprising: a base 1; a limiter 2, the limiter 2 is used to limit the steel coil, and the outer wall of the limiter 2 is fixedly connected to the outer wall of the base 1; a tensioner 3, the tensioner 3 is used to tension the steel coil, and the outer wall of the tensioner 3 is rotatably connected to the inner wall of the base 1.

[0018] The tensioner 3 includes a rotating shaft 31, the outer wall of which is fixedly connected with a lifting device 34, a rotating column 32 is fixedly connected to the side of the rotating shaft 31 close to the base 1, a protective shell 33 is fixedly connected to the end of the rotating shaft 31 away from the rotating column 32, a movable device 35 is fixedly connected to the side of the protective shell 33 close to the rotating shaft 31, the side of the rotating shaft 31 close to the rotating column 32 is slidably connected to the outer wall of the base 1, the outer wall of the rotating column 32 is rotatably connected to the inner wall of the base 1, and the lifting device 34 in the tensioner 3 is provided to tension the steel coil on the tensioning device. Before the steel coil is placed on the lifting block 341, the top arc surface of the lifting block 341 is lower than the top arc surface of the blocking plate 351 to facilitate the insertion of the steel coil.

[0019] The lifting device 34 includes a connecting block 343, a stepping motor 346 is arranged outside the connecting block 343, the outer wall of the connecting block 343 is slidably connected to the sliding block 342, the outer wall of the sliding block 342 is fixedly connected to the lifting block 341, the inner wall of the lifting block 341 close to the sliding block 342 is slidably connected to the movable plate 345, the inner wall of the movable plate 345 is rotatably connected to the rotating rod 344 through a movable groove 3452, and the movable groove 3452 is opened in the wall of the movable plate 345, and the inner wall of the movable plate 345 is connected to the rotating rod 344 through a movable groove 3452. The threaded hole 3451 is rotatably connected to a bidirectional screw 347, and the threaded hole 3451 is opened in the wall of the movable plate 345. The outer wall of the bidirectional screw 347 is fixedly connected to the output end of the stepper motor 346. The middle part of the outer wall of the bidirectional screw 347 is rotatably connected to the limit block 348. When the steel coil is placed on the lifting block 341, the stepper motor 346 is started, so that the stepper motor 346 drives the bidirectional screw 347 to rotate. Since both ends of the bidirectional screw 347 are connected to the movable plate 345 through the threaded hole 3451, and the movable plate 345 is The plate 345 is limited by the lifting block 341 and is difficult to rotate, so the rotating bidirectional screw 347 will drive the movable plate 345 to rotate. At the same time, since the rotation directions of the bidirectional screw 347 are opposite, and the bidirectional screw 347 is further prevented from axial movement by the limiting block 348, the two movable plates 345 can be close to or away from each other. At this time, the lifting device 34 is required to support the inner wall of the steel coil, so as to drive the two movable plates 345 to move closer to each other. Since the end of the rotating rod 344 away from the movable plate 345 is connected The connecting block 343 is shaped like two plates connected by a cross bar in the middle, and the cross bar passes through the rotating rod 344 and positions the rotating rod 344. Therefore, when the movable plates 345 approach each other, they will be lifted up due to the movement of the rotating rod 344 in the movable groove 3452, thereby causing the lifting block 341 and the sliding block 342 to move along the outer wall of the connecting block 343 and support the inner wall of the steel coil. The lifting device 34 on the rotating shaft 31 applies a thrust to the inside of the steel coil, thereby tensioning the inner wall of the steel coil.

[0020] The movable device 35 includes a blocking plate 351, the outer wall of the blocking plate 351 is fixedly connected with a clamping block 352, the outer wall of the clamping block 352 is slidably connected to the inner wall of the movable ring 353, the inner wall of the movable ring 353 is fixedly connected to the outer wall of the stepping motor 346, the inner wall of the blocking plate 351 is slidably connected to the outer wall of the bidirectional screw 347 through a sliding groove 354, and the sliding groove 354 is opened in the wall of the blocking plate 351, the outer wall of the blocking plate 351 and the outer wall of the clamping block 352 are both fixedly connected to the outer wall of the rotating shaft 31, the middle part of the outer wall of the rotating shaft 31 is fixedly connected to the end of the connecting block 343 away from the lifting block 341, and the end of the rotating rod 344 away from the movable plate 345 is rotated with the outer wall of the connecting block 343 The lifting device 34 can be adjusted smoothly by the movable device 35, and the synchronous driving of the stepper motor 346 makes the lifting device 34 on the rotating shaft 31 lift and fall back at the same time. Since the lifting block 341 of the lifting device 34 will drive the bidirectional screw 347 to move during the lifting process, the stepper motor 346 needs to move at the same time. The stepper motor 346 is clamped by the movable ring 353. When the bidirectional screw 347 moves upward through the sliding groove 354 of the blocking plate 351, the movable ring 353 slides between the clamping blocks 352, so that the stepper motor 346 has a movable range.

[0021] Working principle:

[0022] When in use, a lifting device 34 in the tensioner 3 is set to tension the steel coil on the tensioning device. Before the steel coil is placed on the lifting block 341, in order to facilitate the insertion of the steel coil, the top arc surface of the lifting block 341 is lower than the top arc surface of the blocking plate 351. When the steel coil is placed on the lifting block 341, the stepper motor 346 is started, so that the stepper motor 346 drives the bidirectional screw 347 to rotate. Since the two ends of the bidirectional screw 347 are connected to the movable plate 345 through the threaded holes 3451, and the movable plate 345 is limited by the lifting block 341 and is difficult to rotate, the rotating bidirectional screw 347 will drive the movable plate 345 to rotate. At the same time, since the rotation directions of the bidirectional screw 347 are opposite, and the bidirectional screw 347 is further prevented from axial movement by the limit block 348, the two movable plates 345 can approach or move away from each other. At this time, the lifting device 34 is required to support the inner wall of the steel coil, so the two movable plates 3 The movable plates 345 are moved closer to each other because the end of the rotating rod 344 away from the movable plate 345 rotates on the connecting block 343. The connecting block 343 is in the shape of two plates connected by a cross bar in the middle. The cross bar penetrates the rotating rod 344 and positions the rotating rod 344. Therefore, when the movable plates 345 are moved closer to each other, the movement of the rotating rod 344 in the movable groove 3452 causes the lifting block 341 and the sliding block 342 to move along the outer wall of the connecting block 343 and to support the inner wall of the steel coil. The lifting device 34 on the rotating shaft 31 applies a thrust to the inside of the steel coil, thereby tensioning the inner wall of the steel coil, and then making the outer wall of the steel coil fit the limiter 2, so that the movement of the steel coil is more stable. At the same time, the friction force is increased by applying pressure. When the external stamping mechanism pulls the steel coil due to production, the rotating shaft 31 can stably rotate in the base 1 through the rotating column 32 due to the friction force, thereby making it difficult for the steel coil to get stuck.

[0023] The movable device 35 in the tensioner 3 is provided to ensure that the lifting device 34 can be adjusted smoothly. At the same time, the synchronous drive of the stepper motor 346 makes the lifting device 34 on the rotating shaft 31 lift up and fall back at the same time. Since the lifting block 341 of the lifting device 34 will drive the bidirectional screw 347 to move during the lifting process, the stepper motor 346 needs to move at the same time at this time. The stepper motor 346 is clamped by the movable ring 353. When the bidirectional screw 347 moves upward through the sliding groove 354 of the blocking plate 351, the movable ring 353 slides between the clamping blocks 352, so that the stepper motor 346 has a movable range, so that the stepper motor 346 can move synchronously with the bidirectional screw 347, so that the lifting device 34 can move smoothly. The protective shell 33 is provided to protect the stepper motor 346. Since the stepper motor 346 has the ability of pulse starting, the stepper motor 346 on the tensioner 3 can be started at the same time, so that the applied force during tensioning is more uniform, so that the operation effect of the tensioner 3 is better.
