Description

Technical Field

[0001] This utility model relates to the field of centering device technology, specifically a strip steel threading centering device. Background Technology

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel is also known as steel strip. During its production and processing, it needs to be threaded on the rolling mill. During the threading process, the strip steel needs to be conveyed and displaced on the roller stand. Due to the long threading distance and the lack of guiding devices, the strip steel may deviate during the threading process. When it is transmitted to the subsequent equipment, the position will be offset, making it impossible to achieve precise processing of the strip steel. Due to the frequent deviation, the strip steel cannot be cut and passes through the equipment normally. It is necessary to stop the machine and manually straighten it before passing through, which affects the production efficiency of the unit and is unstable during the operation of personnel, which can easily cause accidents. Utility Model Content

[0003] The purpose of this utility model is to provide a strip threading and centering device to solve the problem mentioned in the background art, which is that due to the long strip threading distance and the lack of a guiding device, the strip may deviate during the threading process, resulting in a positional shift when transmitted to subsequent equipment, thus making it impossible to achieve precise processing of the strip.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a strip threading and centering device, comprising:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment of this utility model provides: a strip threading and centering device, comprising:

[0023] The lifting assembly 1 includes a column 11 with a crossbar 13 fixedly connected to its bottom and an adjusting rod 12 inserted inside the column 11; an adjusting assembly 2 and a support plate 3, the adjusting assembly 2 including a housing 21 fixedly connected to the top of the adjusting rod 12 and a support plate 3 fixedly connected to the top of the housing 21, with the moving end of the adjusting assembly 2 symmetrically sliding on the upper surface of the support plate 3; and a positioning clamp 4 sleeved on the outside of the moving end of the adjusting assembly 2, with a rotating shaft 41 fixedly connected to the upper surface of the positioning clamp 4. The outer wall of the rotating shaft 41 is rotatably connected to a limiting roller 42 via a ball bearing. By sliding the positioning clamp 4, the position of the limiting roller 42 can be adjusted, thereby better adapting to the roller spacing for centering and limiting. Driven by the adjusting assembly 2, the moving end drives the limiting rollers 42 on both sides for centering and clamping, completing the auxiliary centering process for the strip steel and preventing it from deviating.

[0024] Furthermore, a positioning hole is provided at the top of the column 11, and adjustment holes are evenly provided on the adjusting rod 12. Fastening bolts pass through the adjustment holes and the positioning holes. By adjusting the height of the column 11 and the adjusting rod 12, the height of the limiting roller 42 can be flexibly adjusted, thereby better realizing the use of roller frames of different heights and greatly improving the adaptability of the device.

[0025] Furthermore, the adjusting assembly 2 includes a housing 21, with a main shaft 22 rotatably connected inside the housing 21. A gear 23 is fixedly connected to the outer wall of the main shaft 22, and two rack shafts 24 mesh with the outer side of the gear 23. Guide plates 25 are respectively connected to the ends of the two rack shafts 24 that are far apart from each other. An adjusting plate 26 is fixedly connected to the upper surface of the guide plate 25. By installing a motor at the bottom of the housing 21, the main shaft 22 is driven to rotate by the power of the motor. The gear 23 further drives the rack shafts 24 to move left and right. Thus, the displacement of the guide plate 25 and the adjusting plate 26 drives the limiting roller 42 to move, thereby completing the centering and clamping of the strip steel and effectively preventing the strip steel from deviating during conveying.

[0026] Furthermore, both ends of the main shaft 22 are rotatably connected to the housing 21 via bearings. Both the housing 21 and the support plate 3 are provided with guide grooves to accommodate the left and right displacement of the guide plate 25. The guide grooves provide auxiliary limiting for the sliding of the guide plate 25, thereby improving the stability of the left and right displacement of the adjusting plate 26. The guide plate 25 has a T-shaped structure, and a threaded hole is provided at the center of the upper surface of the guide plate 25. The adjusting plate 26 is provided with a countersunk positioning hole corresponding to the threaded hole of the guide plate 25. The adjusting plate 26 is connected to the guide plate 25 by a countersunk screw, allowing for disassembly and maintenance of both.

[0027] Furthermore, the adjusting plate 26 is the moving end of the adjusting component 2. The adjusting plate 26 has through holes evenly distributed. The positioning clamp 4 is U-shaped and sleeved on the outer wall of the adjusting plate 26. The positioning clamp 4 has a positioning hole corresponding to the through hole of the adjusting plate 26. The positioning hole and the through hole are connected by fastening bolts. The fastening bolts ensure the stability of the positioning of the positioning clamp 4, thereby ensuring the stability of the centering and clamping of the strip steel.

[0028] Furthermore, each adjusting plate 26 is externally connected to at least two sets of positioning clips 4, and each set of positioning clips 4 has the same external structure. The adjusting plate 26 slides against the upper surface of the support plate 3. The inner wall of the housing 21 is also fixedly connected to a support tube 27, and the support tube 27 is sleeved on the outside of the rack shaft 24. The support tube 27 is provided for auxiliary support of the rack shaft 24 to ensure the stability of the left and right displacement of the rack shaft 24.

[0029] Working principle: The gear 23 and rack shaft 24 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. When using this utility model, the device is first installed so that it is placed below the roller frame. Then, according to the height and spacing of the rollers, the height and spacing of the limiting roller 42 are adjusted so that the limiting roller 42 is between the two rollers. Then, the gear 23 is driven to rotate by the main shaft 22. The guide plate 25 and the adjusting plate 26 are displaced by the rack shaft 24. Thus, the clamping and centering of the strip steel is completed by the displacement of the limiting roller 42, ensuring the stability of the strip steel conveying and avoiding its deviation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
