DETAILED DESCRIPTION

[0020] The present application will be further described in detail below in combination with the drawings and specific embodiments. The embodiments of the present application are given for the purpose of illustration and description, and are not exhaustive or limit the present application to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described in order to better illustrate the principles and practical application of the present application, and to enable those skilled in the art to understand the present application so as to design various embodiments with various modifications suitable for specific purposes.

[0021] Please refer to Figures 1-4 In this embodiment, a high-precision punching device for producing automobile bright strips is provided, which comprises a workbench 1, a fixed frame 2 fixedly connected above the workbench 1, a cutting blade 21 installed on the fixed frame 2, a cutting groove 11 provided below the cutting blade 21 above the workbench 1, a conveying roller 3 installed on one side of the fixed frame 2 on the workbench 1, a limiting mechanism 4 for limiting the bright strip installed on one side of the conveying roller 3 on the workbench 1, and a pulling mechanism 5 for pulling the bright strip installed on the other side of the fixed frame 2 on the workbench 1.

[0022] In use, the bright strip is limited by the limiting mechanism 4 and then passes below the cutting blade 21, and one end of the bright strip is clamped by the pulling mechanism 5 to pull the bright strip to move, so that the bright strip is straightened by the pulling force, and errors are less likely to occur during cutting.

[0023] In further embodiments, please refer to Figure 2 The limiting mechanism 4 comprises a limiting cover 41 located on the extension line of the symmetry axis of the conveying roller 3, limiting rods 42 fixedly connected on both sides of the limiting cover 41 on the workbench 1, the limiting rods 42 penetrating through both sides of the limiting cover 41, and springs 43 provided on one side of the limiting cover 41 outside the limiting rods 42. One end of the bright strip is conveyed to the inside of the limiting cover 41 by the conveying roller 3, and the limiting cover 41 limits the bright strip to pass below the cutting blade 21.

[0024] In further embodiments, please refer to Figures 3-4 The pulling mechanism 5 comprises a moving cover 51, clamping plates 53 slidingly connected on both sides of the moving cover 51, the clamping plates 53 inserted into the inside of the moving cover 51 at one end, telescopic rods 54 fixedly installed at both ends of the moving cover 51, and connecting rods 55 connected between one end of the telescopic rods 54 and the clamping plates 53. By extending the telescopic rods 54, one end of the telescopic rods 54 pushes the clamping plates 53 to insert into the inside of the moving cover 51 through the connecting rods 55, so that one end of the bright strip between the clamping plates 53 is clamped, and the subsequent one end of the bright strip can be pulled to move.

[0025] When the bright strip is cut, one end of the bright strip remains outside one end of the limiting cover 41, the moving cover 51 approaches the limiting cover 41 under the action of the driving mechanism, the moving cover 51 continues to move after contacting the limiting cover 41, and the moving cover 51 pushes the limiting cover 41 to move after moving (for example Figure 4 At this time, one end of the bright strip originally in the inside of the limiting cover 41 is located in the inside of the moving cover 51, and is clamped and pulled by the clamping plates 53. In this way, the clamping plates 53 can stably clamp one end of the bright strip after abutting.

[0026] In a further embodiment, a driving mechanism is provided below the workbench 1. The driving mechanism includes a lead screw and a drive motor. An internal thread block is provided on the outer side of the lead screw. A sliding groove 12 is provided on the workbench 1. The internal thread block passes through the sliding groove 12 and is fixedly connected to the movable cover 51. The drive motor is fixedly installed below the workbench 1. The lead screw is rotatably connected to the lower end of the workbench 1. The drive motor starts, thereby driving the lead screw to rotate. The rotation of the lead screw drives the non-rotating internal thread block to move along the sliding groove 12. The internal thread block is connected to the end of the movable cover 51 away from the limiting cover 41. The internal thread block drives the movable cover 51 to move. At the same time, since the width of the sliding groove 12 is greater than the width of the bright strip, and the lower end of the movable cover 51 is open, when the bright strip is cut, the bright strip is located above the sliding groove 12. The other end of the bright strip is released by the clamping plate 53, allowing the bright strip to fall from the sliding groove 12, thereby unloading the material.

[0027] In a further embodiment, see Figure 3 The movable cover 51 has an expansion port 52 at one end, and the width of the expansion port 52 is greater than the width of the limiting cover 41. The expansion port 52 can guide the unfixed end of the bright strip after it has been cut, so that the broken end of the bright strip can enter the interior of the movable cover 51 more easily.

[0028] In a further embodiment, see Figure 2 The movable cover 51 and the limiting cover 41 are located on the same straight line, and the movable cover 51 and the limiting cover 41 are at the same height. This ensures that the movable cover 51 can fit into the limiting cover 41 after movement, thereby ensuring that the bright strip can stably enter the interior of the movable cover 51.

[0029] In a further embodiment, see Figure 1 The fixing frame 2 is equipped with a telescopic mechanism, which is connected to the cutting blade 21. By extending the telescopic mechanism, the cutting blade 21 can be lowered, and after the cutting blade 21 is lowered, it cuts the bright strip on one side of the limiting cover 41.

[0030] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
