Description

Technical Field

[0001] This utility model relates to the field of metal strip processing technology, and in particular to a metal strip stepping displacement device. Background Technology

[0002] In metal processing production, it is often necessary to cut strip. Metal strip is usually wound on a winding drum. During processing, the winding drum is placed on the unwinding rod, and then the metal strip is conveyed to the processing device through a displacement device.

[0003] A search revealed a Chinese patent publication number CN219408546U, which discloses a composite metal strip feeding device. The device includes an operating table with a rectangular groove at its top and a through hole on its left side. A feeding mechanism is fixedly connected to the bottom inner side of the rectangular groove, and a clamping mechanism is fixedly connected to the inner side of the rectangular groove. A groove is formed on the inner side of the rectangular groove, and a servo motor is threaded into the groove. A first roller is mounted on the output shaft of the servo motor. This patent utilizes two winding drums. After the composite metal strip body on the first winding drum is completely drawn out, the composite metal strip clamped at the bottom of the bolt can be directly removed, and then the second composite metal strip can be fed, thereby improving feeding efficiency. However, it guides the metal strip through the opening, but since the metal strip has different specifications and the opening size is fixed, it is not convenient to guide metal strips of different specifications.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Example 1 A metal strip stepping displacement device, such as Figures 1 to 3 As shown, the workbench 1 is included. The top outer wall of the workbench 1 is connected to two opposing limiting rods 3 via a bidirectional moving assembly 2. The limiting rods 3 are L-shaped. Multiple positioning assemblies 4 are provided on the top outer wall of the limiting rods 3. The positioning assembly 4 includes a moving rod 5 and a spring 6. The moving rod 5 is vertically slidably connected to the limiting rod 3. The spring 6 is sleeved on the outer wall of the moving rod 5. The two ends of the spring 6 are respectively connected to the moving rod 5 and the limiting rod 3. A connecting frame 7 is fixedly connected to the bottom end of the moving rod 5. The connecting frame 7 is U-shaped. A rotating roller 8 that rolls and rubs against the top outer wall of the metal strip is rotatably connected to the inner wall of the connecting frame 7.

[0022] The bidirectional moving assembly 2 includes a slide groove 9 and a bidirectional threaded rod 10. The slide groove 9 is opened on the top outer wall of the workbench 1. The bidirectional threaded rod 10 is rotatably connected to the inner wall of the slide groove 9. One end of the bidirectional threaded rod 10 is connected to a rotating handle. Both ends of the inner wall of the slide groove 9 are slidably connected to moving blocks 11. The two moving blocks 11 are respectively threaded with the outer walls of the two ends of the bidirectional threaded rod 10. The two limiting rods 3 are respectively fixedly connected to the top outer walls of the two moving blocks 11.

[0023] The top outer wall of the workbench 1 is provided with two parallel guide bars 12. The two guide bars 12 are located outside the two limit rods 3 respectively. The outer walls of the two guide bars 12 are slidably connected to the same sliding frame 13. The top outer wall of the workbench 1 is equipped with a telescopic rod 14 for pushing the sliding frame 13 to move. The side wall of the sliding frame 13 is equipped with a telescopic rod 15. The telescopic end of the telescopic rod 15 is connected to a fixing plate 16 through a connecting assembly. Both ends of the bottom outer wall of the fixing plate 16 are fixedly connected with connecting pins 17. Positioning holes that cooperate with the connecting pins 17 are opened on both sides of the metal strip.

[0024] All electrical components in this embodiment are connected to an external controller and external mains power, and the controller can be a conventional known device such as a computer that performs control.

[0025] In use, rotate the bidirectional threaded rod 10 to move the two moving blocks 11 towards or away from each other along the bidirectional threaded rod 10. Adjust the distance between the two limiting rods 3 according to the width of the metal strip. The metal strip passes through the two limiting rods 3, and the rotating roller 8 contacts the top outer wall of the metal strip. The spring force of the spring 6 presses the metal strip onto the surface of the worktable 1, restricting the vertical movement of the metal strip. Then, the telescopic rod 2 15 pushes the fixed plate 16 down, allowing the connecting pin 17 to be inserted into the positioning hole. Then, the telescopic rod 14 pushes the sliding frame 13 to move, driving the metal strip to move towards the processing device. The moving distance is a multiple of the distance between adjacent positioning holes on the metal strip. Then, the telescopic rod 2 15 drives the fixed plate 16 up, and the connecting pin 17 disengages from the positioning hole. The telescopic rod 14 drives the sliding frame 13 to reset. Repeat the above steps to feed the metal strip by step displacement.

[0026] By setting up a bidirectional moving component 2, a limiting rod 3 and a positioning component 4, the device can limit the movement of metal strips of different specifications, thereby improving the practicality of the device. In addition, the rotating roller 8 rolls and rubs against the surface of the metal strip, reducing the friction on the metal strip.

[0027] By providing guide bars 12, sliding frames 13, telescopic rod one 14, telescopic rod two 15, fixing plates 16, and connecting pins 17, and in conjunction with positioning holes on both sides of the metal strip, the metal strip can be fed in a step-by-step manner, achieving precise fixed-length feeding and more stable feeding.

[0028] Example 2 A metal strip stepping displacement device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 4 As shown, the connecting assembly includes a connecting plate 18 and two wing bolts 19. The connecting plate 18 is fixedly connected to the telescopic end of the telescopic rod 15. The fixing plate 16 is located below the connecting plate 18. The two wing bolts 19 are threadedly connected to both ends of the connecting plate 18. Threaded holes that engage with the wing bolts 19 are provided at both ends of the top outer wall of the fixing plate 16.

[0029] When the specifications of the conveyed metal strip change, the worker can manually rotate the wing bolt 19 until the bottom end of the wing bolt 19 disengages from the threaded hole, remove the fixed plate 16, then select the corresponding fixed plate 16 and place it under the connecting plate 18. Rotate the wing bolt 19, and the bottom end of the wing bolt 19 will screw into the threaded hole to fix the fixed plate 16.

[0030] With the addition of connecting components, users can easily replace the fixing plate 16 by hand.

[0031] Working principle: In use, rotating the bidirectional threaded rod 10 causes the two moving blocks 11 to move towards or away from each other along the bidirectional threaded rod 10. The distance between the two limiting rods 3 is adjusted according to the width of the metal strip. The metal strip passes between the two limiting rods 3, and the rotating roller 8 contacts the top outer wall of the metal strip. The spring force of the spring 6 presses the metal strip onto the surface of the worktable 1, restricting the vertical movement of the metal strip. Then, the telescopic rod 2 15 pushes the fixed plate 16 downwards, causing the connecting pin 17 to insert into the positioning hole. Then, the telescopic rod 1 14 pushes the sliding frame 13 to move, driving the metal strip towards the processing device. The moving distance is [missing information - likely a distance in the original text]. The distance between adjacent positioning holes on the strip is a multiple of the distance between the two telescopic rods 15 and 16. Then, the connecting pin 17 disengages from the positioning hole, and the telescopic rod 14 drives the sliding frame 13 to reset. The above steps are repeated to make the metal strip move forward and be fed. When the specifications of the conveyed metal strip change, the operator can manually rotate the wing bolt 19 until the bottom end of the wing bolt 19 disengages from the threaded hole, remove the fixed plate 16, and then select the corresponding fixed plate 16 to place under the connecting plate 18. Rotate the wing bolt 19, and the bottom end of the wing bolt 19 is screwed into the threaded hole to fix the fixed plate 16.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
