Description

Technical Field

[0001] The utility model relates to the technical field of shape wire tube steel rolling technology, and particularly relates to a template for roll marking positioning. Background Technique

[0002] In the steel manufacturing industry, as the cornerstone of railway transportation, the quality control in the production process of steel rails is of crucial importance. The production of steel rails involves multiple links, among which the roll, as a key device, plays a decisive role in the forming process of steel rails. To ensure the traceability and quality control of steel rails, precise marking operations need to be carried out on the finished rolls before the production of each steel rail to mark key information such as the production plant information, specification model, material composition, and production date.

[0003] Traditional roll marking methods highly rely on the experience of operators and manual operations. Specifically, operators need to first determine the marking position through complex calculations by referring to the design drawings, and then use simple tools such as a scale to manually measure and mark on the roll surface. This method is not only cumbersome and inefficient, but also greatly affected by human factors, and it is difficult to guarantee the measurement accuracy. Especially on large-scale and high-efficiency steel rail production lines, this manual measurement and marking method has become a major bottleneck restricting the improvement of production efficiency and product quality control. First of all, manual measurement takes a long time, and as the production rhythm speeds up, operators are prone to fatigue, resulting in an increase in measurement errors and affecting the accuracy of the marking position. Secondly, due to the limitations of measurement tools and the differences in the skill levels of operators, the accuracy of the marking position often fails to meet high-standard requirements, thereby affecting the overall quality control of steel rail products. In addition, frequent measurement and marking operations also increase the labor intensity of operators, reduce work efficiency, and are not conducive to the cost control of enterprises and the improvement of market competitiveness. Therefore, we propose a template for roll marking positioning to solve the above problems. Content of the Utility Model

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0020] As Figure 1-2As shown in the figure, a template for roll marking positioning proposed by an embodiment of the present utility model includes a bottom plate 1. One side of the bottom plate 1 is fixedly connected with a backing plate 2. The top of the bottom plate 1 is provided with a plurality of marking blocks 4. The included angle between the bottom plate 1 and the backing plate 2 is an arc 3. The bottom plate 1 and the backing plate 2 form an L-shaped template. Before roll marking, the operator first finds the corresponding marking block 4 on the bottom plate 1 according to the specifications of the rails to be produced, and presses the backing plate 2 tightly against the surface of the roll to ensure the close fit between the template and the roll. By observing the position of the marking block 4, the operator can quickly determine the specific position of the trademark center of the rails of this specification on the roll. Subsequently, the operator adjusts the marking machine to this position for precise marking operations, so as to quickly position the roll marking center position, improve the marking efficiency, with high positioning accuracy and small offset tolerance. One template can position the trademark positions of multiple different specifications of rails, and can also be used as a trademark position inspection template to check the marking quality.

[0021] In some embodiments, two first chamfered portions 5 are provided on the left side of the bottom plate 1, a second chamfered portion 6 is provided at the bottom of the backing plate 2, and a third chamfered portion 7 is provided on the right side of the bottom plate 1. The chamfering treatment can remove the sharp parts at the edges of the template, reducing the risk of cutting the hands or other contact parts of the operator during the operation. Especially when the template is in close contact with or moving on the roll, these chamfered portions can effectively reduce the injuries caused by friction or collision. The design of the chamfered portions helps the smooth assembly and positioning of the template on the roll. They can serve as guiding surfaces to help the template more easily fit and align with the expected marking position on the roll. In addition, when fine-tuning the position of the template is required, the chamfered portions can also provide a certain tolerance space, making the adjustment process smoother. During the contact process between the template and the roll, the chamfered portions can reduce the direct contact area between the two, thereby reducing the heat and wear generated by friction. This is of great significance for protecting the surface of the roll and extending the service life of the template.

[0022] In some embodiments, the bottom plate 1 and the backing plate 2 are in the shape of thin sheets, and the thicknesses of the bottom plate 1 and the backing plate 2 are consistent. The thin-sheet-shaped bottom plate 1 and backing plate 2 can fit more closely to the surface of the roll, reducing the positioning error caused by thickness differences or unevenness. This close fit helps to ensure the precise correspondence between the marking block 4 and the expected marking position on the roll, thereby improving the accuracy of marking.

[0023] Working principle or structural principle. During use, the bottom plate 1 serves as the basic support part of the template to ensure the stability and durability of the template. The backing plate 2 is closely attached to the surface of the roll and serves as a positioning reference to ensure the accuracy of measurement and marking. The arc 3 is designed according to the curvature of the roll, enabling the template to perfectly fit the surface of the roll and reducing the positioning error. The marking blocks 4 clearly mark the distances from the center positions of trademarks of various specifications of steel rails to the side wall on the operating side of the finished roll on the template. These marking blocks 4 are based on the data accurately measured in the pass profile drawing of the finished roll in advance, ensuring the accuracy and reliability of the markings. The first chamfer part 5, the second chamfer part 6, and the third chamfer part 7. These design details help reduce the friction and wear between the template and the roll, and at the same time improve the positioning accuracy. When positioning, before marking the roll, the operator first finds the corresponding marking block 4 on the bottom plate 1 according to the specifications of the steel rail to be produced, presses the backing plate 2 tightly against the surface of the roll to ensure the close fit between the template and the roll. By observing the position of the marking block 4, the operator can quickly determine the specific position of the center of the trademark of this specification of steel rail on the roll. Subsequently, the operator adjusts the marking machine to this position for precise marking operations, thus being able to quickly position the marking center of the roll, improving the marking efficiency, with high positioning accuracy and small offset tolerance. One template can position the trademark positions of multiple different specifications of steel rails and can also be used as a trademark position inspection template to check the marking quality.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
