Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing technology, specifically to a self-calibrating limiting device for wire drawing of metal strip surfaces. Background Technology

[0002] Metal strip is a commonly used industrial basic material in the field of metal processing. It usually refers to industrial strip material made from pure metal or alloy as raw material through cold rolling and longitudinal cutting processes. After the metal strip is formed, in order to improve its appearance, its surface is usually brushed. Metal surface brushing is a decorative surface treatment method that forms lines on the surface of the workpiece by grinding products. The metal strip is transported to the brushing mechanism through the transfer roller to form the texture.

[0003] To ensure that the metal strip does not shift during the wire drawing process, the current method involves installing a limiting device on the transfer roller and calibrating and limiting it by contacting both sides of the metal strip. However, the current calibration limiting device is fixed after installation and cannot be freely calibrated and adjusted according to metal strips of different widths, which is inconvenient to use.

[0004] Based on this, this utility model designs a self-calibrating limiting device for wire drawing of metal strip surface to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] In some embodiments, please refer to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 and Figure 4 A self-calibrating limiting device for drawing the surface of metal strip includes two sets of side plates 1 and calibration limiting components. Lower transmission rollers 2 rotate symmetrically on both sides of the center of the side plates 1. A drawing base frame 3 is fixed at the center of the side plates 1, and side transmission rollers 4 are arranged on both sides of the drawing base frame 3, rotating between the side plates 1. A drawing component is installed at the top of the side plates 1, including a top plate 5, an upper cylinder 6, a lifting plate 7, a drawing roller brush 8, and a rotating motor 9. The calibration limiting components include a limiting screw 10, a lower limiting rod 11, a side limiting rod 12, a limiting screw sleeve 13, a limiting sleeve 14, a limiting disc 15, and a linkage component. Positioning screw 10 is located below a set of lower transmission rollers 2 and rotates through side plate 1. Lower limiting rod 11 is located below another set of lower transmission rollers 2. Side limiting rod 12 is located below side transmission roller 4. Limiting screw sleeve 13 is symmetrically threaded on both sides of the center of limiting screw 10. Limiting sleeve 14 is symmetrically and movably sleeved on both sides of the center of lower limiting rod 11 and side limiting rod 12. Limiting disc 15 is movably and symmetrically sleeved on both sides of the center of lower transmission roller 2 and side transmission roller 4. Limiting disc 15 is fixedly connected to limiting screw sleeve 13 and limiting sleeve 14. Linkage component connects limiting screw sleeve 13 and limiting sleeve 14.

[0027] In this embodiment of the utility model, during use, the calibrating limiting component can be used to rotate the limiting screw 10 according to the width of the metal strip to be transmitted. The threaded engagement between the limiting screw sleeve 13 and the limiting screw 10 causes the two sets of limiting screw sleeves 13 to move towards each other. Under the action of the linkage component, the limiting sleeves 14 on the lower limiting rod 11 and the side limiting rod 12 move synchronously, thereby causing the limiting disks 15 on the lower transmission roller 2 and the side transmission roller 4 to move synchronously, realizing the adjustment of the spacing of the limiting disks 15, thereby limiting the metal strip to be transmitted on both sides. Then, according to the thickness of the metal strip, the upper cylinder 6 is started, the height of the wire drawing brush 8 is adjusted, and the rotating motor 9 is started to drive the wire drawing brush 8 to rotate, so that the surface of the metal strip is wire drawn when it passes through.

[0028] In this embodiment of the utility model, by setting a calibration limiting component, the spacing of the limiting disk 15 can be freely adjusted according to the thickness of the metal strip to be processed, thereby limiting the metal strip to be transmitted on both sides for easy use; by setting an upper cylinder 6, the height of the drawing roller brush 8 can be adjusted according to the thickness of the metal strip, making it easier to draw the surface of the metal strip.

[0029] In one embodiment of this utility model, the lower conveyor roller 2 is located at the lower center of the side plate 1, the wire drawing bottom frame 3 and the side conveyor roller 4 are located at the upper center of the side plate 1, the top plate 5 is fixed at the top center of the side plate 1, the upper cylinder 6 is installed at the top center of the top of the top plate 5 and the piston rod moves through the top plate 5 and is connected to the lifting plate 7, the wire drawing brush 8 rotates at the bottom center of the lifting plate 7 and is connected to the output end of the rotating motor 9, the rotating motor 9 is installed at the bottom of the lifting plate 7; auxiliary rollers 16 rotate at equal intervals inside the wire drawing bottom frame 3, the top of the auxiliary rollers 16 is flush with the top of the side conveyor roller 4, the length of the wire drawing brush 8 is equal to the length of the auxiliary rollers 16, and the length of the thread on the limiting screw 10 is slightly greater than the length of the auxiliary rollers 16. When the metal strip is conveyed between the side conveyor rollers 4, it is assisted by the auxiliary rollers 16 to facilitate the conveying;

[0030] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the linkage includes a horizontal connecting rod 17 and a diagonal connecting rod 18. The horizontal connecting rod 17 is threadedly connected to the limiting sleeve 13 and the limiting sleeve 14 on the lower limiting rod 11. The diagonal connecting rod 18 is threadedly connected to the limiting sleeve 13 and the limiting sleeve 14 on the side limiting rod 12. The diagonal connecting rod 18 is also threadedly connected to the limiting sleeve 14 on the lower limiting rod 11 and the limiting sleeve 14 on the side limiting rod 12. An adjusting component is installed on the side of the side plate 1. The adjusting component includes a slide groove 19, a lower slide block 20, a mounting plate 21, a base frame 22, and a lower cylinder 23. The slide groove 19 is located on the side of the side plate 1 and penetrates through the side plate. The top and two opposite sides are provided with a sliding block 20 sliding in the slide groove 19. The end of the sliding block 20 is flush with the side of the side plate 1. The wire drawing bottom frame 3 is threadedly fixed to the sliding block 20 by the mounting plate 21. The bottom frame 22 is set at the bottom edge of the wire drawing bottom frame 3. The piston rod inside the lower cylinder 23 is connected to the bottom end of the bottom frame 22. The top plate 5 has through grooves 24 on both sides. The upper sliding block 25 slides in the slide groove 19. The lifting plate 7 is threadedly fixed to the upper sliding block 25. The side of the wire drawing bottom frame 3 is fixed with a mating plate 26. The side transmission roller 4 and the side limiting rod 12 are set on the mating plate 26.

[0031] In this embodiment of the invention, during use, the calibrating limiting component can be used to rotate the limiting screw 10 according to the width of the metal strip to be conveyed. The threaded engagement between the limiting sleeve 13 and the limiting screw 10 causes the two sets of limiting sleeves 13 to move towards each other. Under the action of the horizontal connecting rod 17 and the inclined connecting rod 18, the limiting sleeves 14 on the lower limiting rod 11 and the side limiting rod 12 move synchronously, thereby causing the limiting discs 15 on the lower conveying roller 2 and the side conveying roller 4 to move synchronously. This adjusts the spacing of the limiting discs 15, thus allowing the metal strip to be conveyed to move smoothly. The strip is limited on both sides to prevent it from deviating. Then, using the adjusting component, the lower cylinder 23 is activated. With the sliding cooperation of the slide groove 19 and the lower slider 20, the wire drawing bottom frame 3 moves upward, thereby adjusting the height of the side transmission roller 4 and the auxiliary roller 16 to achieve the tension adjustment of the metal strip, which is beneficial for wire drawing. Finally, according to the thickness of the metal strip, the upper cylinder 6 is activated. With the cooperation of the upper slider 25 and the slide groove 19, the height of the wire drawing brush 8 is adjusted. The rotating motor 9 is started to drive the wire drawing brush 8 to rotate, and the surface of the metal strip is wire drawn as it passes through.

[0032] In this embodiment of the utility model, by setting an adjusting member, the height of the side conveying roller 4 and the auxiliary roller 16 can be adjusted to realize the tension adjustment of the metal strip, which is beneficial to wire drawing; by setting a through groove 24 and an upper slider 25, the height of the wire drawing roller brush 8 can be adjusted with the cooperation of the upper slider 25 and the groove 19.
