Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed wire pinch roller adjustment, in particular to a tool for fine adjustment of the roller gap of high-speed wire pinch rollers. Background Art

[0002] In modern industrial production, especially during high-speed wire rolling, pinch rolls play a crucial role. Their primary function is to ensure that the head of the wire rolled out of the finished stand can smoothly enter the laying head for coiling. They also prevent the tail of the wire from losing its restraints during high-speed operation, leading to speed fluctuations and potential steel pile-up accidents. However, existing pinch rolls present several challenges in practical application that require urgent resolution.

[0003] First, due to the diversity of rolling specifications and wear of the pinch rolls, the working diameter of the pinch rolls varies, necessitating regular adjustment of the pinch roll gap to maintain production efficiency and product quality. Currently, pinch roll gap adjustment relies primarily on the aid of a sample bar, with a screw for rough adjustment and a disc for fine-tuning. While this method can meet production needs to a certain extent, it has significant shortcomings in actual operation.

[0004] Specifically, when operators use the adjustment disc for precise adjustments, they typically use a pin or iron rod combined with a hammer to strike the pinch roller gap. However, this method presents several significant issues: First, the force applied during the striking process is discontinuous, sometimes strong and sometimes weak, making it difficult to ensure accurate adjustment; second, long-term striking can easily damage the grooves of the adjustment disc, affecting its service life; and finally, the operator needs to distract themselves from observing and measuring while striking, which undoubtedly increases safety risks during operation.

[0005] In response to the above problems, there is an urgent need to develop an improved pinch roller gap adjustment tool to improve adjustment accuracy, reduce equipment damage, and reduce safety risks during operation, thereby improving the operating efficiency and safety of the entire production line.

When the insertion block is inserted into the groove of the pinch roller adjustment disc, the curvature of the inner side of the transition arc is adapted to the outer edge of the pinch roller adjustment disc.

[0010] The handle is a rigid columnar structure capable of applying torque.

[0011] In some embodiments, a corrugated or mesh-shaped anti-slip surface is provided on the side wall of the insertion block.

[0012] In some embodiments, well-shaped reinforcing ribs are provided on the transition arc and the outer side of the handle.

[0036] like Figure 1 and Figure 2 As shown, the first embodiment of the present utility model provides a tool for adjusting a pinch roller adjustment disc 5, comprising an insert block 3, a transition arc 2 and a handle 1 connected in sequence;

[0037] The insert block 3 is a raised structure, which can be inserted into the groove 4 of the pinch roller adjustment disc 5;

[0038] One end of the transition arc 2 is connected to one end of the insertion block 3, and the other end is connected to one end of the handle 1. When the insertion block 3 is inserted into the groove 4 of the pinch roller adjustment disc 5, the curvature of the inner side of the transition arc 2 is adapted to the outer edge of the pinch roller adjustment disc 5;

[0039] The handle 1 is a rigid columnar structure capable of applying torque, for example, it can be a long prism structure or a cylindrical structure.

[0040] The tool of the utility model uses a design in which the insertion block 3, the transition arc 2, and the handle 1 are connected in sequence, so that the operator can easily insert the tool into the groove 4 of the pinch roller adjustment disc 5 and rotate it by applying a torque, thereby improving the convenience and efficiency of the operation. When the tool of the utility model accurately adjusts the roller gap of the pinch roller, it can continuously apply force according to the principle of leverage to make the roller gap adjustment more accurate. In addition, it can avoid the damage caused by the continuous knocking of the pinch roller adjustment disc 5 by the existing technology. Since the traditional method of knocking while observing is avoided, which causes the staff's attention to be distracted and causes safety accidents, the safety of adjusting the roller gap of the pinch roller can be improved.

[0041] like Figure 3 As shown, in the second embodiment of the present invention, the insert block 3 is provided with a corrugated or meshed anti-slip surface 6 on the side wall facing the groove 4. The anti-slip surface 6 on the insert block 3 can increase the friction between the insert block 3 and the groove 4 of the pinch roller adjustment disc 5, preventing the tool from slipping during use, thereby ensuring stability and safety during the adjustment process.

[0042] In order to increase the structural strength of the entire tool, reduce the risk of deformation or damage caused by uneven force during use, and extend the service life of the tool. In some embodiments, the transition arc 2 and the outer side of the handle 1 are provided with reinforcing ribs 10, such as Figure 9 shown.

[0043] In some embodiments, the groove 4 is designed as a cylindrical groove 4 with a circular or polygonal cross-section. The shape matching design of the groove 4 and the insert block 3 ensures a good fit between the tool and the pinch roller adjustment disc 5, making the adjustment action more accurate and avoiding operational difficulties or damage to the groove 4 of the pinch roller adjustment disc 5 caused by shape mismatch.

[0044] In some embodiments, the groove 4 is circular in cross section, and the insert block 3 is cylindrical. The combination of the circular groove 4 and the cylindrical insert block 3 provides more precise positioning, reduces tool shaking during operation, and further enhances the accuracy and reliability of the adjustment process.

[0045] like Figure 4 As shown, in order to increase the comfort of holding the handle 1 and improve the safety of holding it (maintaining a good grip even when the hands are wet and reducing the possibility of accidental slippage), in the third embodiment of the present invention, an anti-slip cover 7 is provided on the outside of the handle 1, and the anti-slip cover 7 is detachably mounted on the outside of the handle 1 to ensure that the anti-slip cover 7 can be replaced at any time after aging.

[0046] like Figure 5As shown, in the fourth embodiment of the present invention, the tool includes a detachable balancing weight 8. The end of the handle 1 away from the insertion block 3 is provided with a threaded structure. The detachable balancing weight 8 is provided with an adapted threaded structure and is removably connected to the end of the handle 1 away from the insertion block 3. The design of the balancing weight 8 optimizes the weight distribution of the tool. When the tool of the present invention becomes "top-heavy" and it is inconvenient to apply force, the installation of the balancing weight 8 can make operation more stable and reduce the operator's fatigue, which is more obvious during long-term use. When the balancing weight 8 is no longer needed, it can also be removed.

[0047] like Figure 6 As shown, in the fifth embodiment of the present utility model, the insertion block 3 includes a double-layer detachable nested structure, including an insertion seat 302 and an outer shell 301, the outer side of the insertion seat 302 includes a threaded structure, and the inner part of the outer shell 301 is provided with a threaded structure adapted to the insertion seat 302, and the external shape is adapted to the groove 4.

[0048] like Figure 7 As shown, in the sixth embodiment of the present invention, the diameter of the insert block 3 at the end facing the groove 4 is smaller than the diameter of the end facing away from the groove 4. The design change of the diameter of the end of the insert block 3 helps to more easily insert the tool into the groove 4 of the pinch roller adjustment disk 5, while providing a better fixing effect during operation and facilitating rapid positioning.

[0049] In the seventh embodiment of the present utility model, as Figure 8 As shown, a cavity 9 is provided inside the handle 1. The cavity 9 design inside the handle 1 reduces the overall weight of the tool, making it lighter and easier to carry, while also providing space for integrating other functions (such as built-in measuring tools, etc.), thereby enhancing the functionality of the tool.

[0050] The following will explain the solution of the present invention in conjunction with other embodiments of the present invention. Those skilled in the art will understand that the following embodiments are only used to illustrate the present invention and should not be regarded as limiting the scope of the present invention.

[0051] In some embodiments of the present invention, the insert block 3, transition arc 2, and handle 1 are integrated. They are cut and ground from 6mm thick Q235 steel plate. The insert block 3 is 24mm long and 16mm wide. The angle between the insert block 3 and the transition arc 2 is 90°. The radius of the transition arc 2 is 80mm. The handle 1 is 248mm long.

[0052] The pinch roller adjustment disc 5 has eight grooves 4, evenly spaced across the disc, with each hole oriented perpendicular to the tangent of the arc. To adjust the pinch roller adjustment disc 5, the operator simply inserts the adjustment tool insert 3 into the grooves 4, aligning the transition arc 2 against the disc. Holding the handle 1, the operator leverages the friction between the grooves 4 and the insert 3 to make precise adjustments.

[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
