Description

Technical Field

[0001] This utility model relates to the field of steel strip inspection technology, and in particular to a tool for measuring the trimming evenness of steel strips. Background Technology

[0002] Steel strip is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. Cold-rolled plates have excellent properties, namely, through cold rolling, thinner and more precise cold-rolled steel strips and plates can be obtained. They have high flatness, high surface smoothness, clean and bright surface, are easy to coat and plate, have many varieties, and are widely used.

[0003] In the production of steel strip products, the steel strip is cut into strips of uniform width to ensure that the sides of the coiled steel strip are neat after winding, thus guaranteeing product consistency. While existing cold-rolled steel strip production technology can achieve thinner and more precise steel strips and plates through cold rolling, ensuring smooth edges and consistent width during cutting and winding remains a pressing technical challenge. Traditional inspection methods can, to some extent, identify whether the overall width of the steel strip meets the standards, but lack effective means to inspect the edge condition. Therefore, it is necessary to avoid edge damage, excessive width, or excessive narrowness in steel strip production to ensure product quality. Currently, there are insufficient methods for inspecting the edge condition and overall width of the steel strip during production. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a steel strip edge trimming evenness measuring tool, which enables real-time detection of the steel strip edge condition, ensuring that the steel strip edge is even and the width is consistent.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tool for measuring the evenness of steel strip trimming, comprising:

[0007] A support assembly, the lower end of which is fixed, and an extension plate is formed at the upper end of which;

[0008] The track assembly includes a support rod, multiple support shafts, and multiple grooved wheels. The support rod is arranged along the direction of movement of the steel strip. The multiple support shafts are arranged vertically and spaced apart on the support rod in sequence. Each grooved wheel is coaxially rotatably connected to the upper end of the corresponding support shaft. The groove on the grooved wheel is used to connect the edge of the steel strip. A horizontally set groove perpendicular to the direction of movement of the steel strip is formed on the support rod, and an extension plate can be slidably inserted into the groove.

[0009] The sensing assembly includes a connecting rod and a displacement sensor. One end of the connecting rod is fixedly connected to the bracket assembly, and the other end of the connecting rod is fixedly connected to the tail end of the displacement sensor. The head end of the displacement sensor is fixedly connected to the support rod, and the displacement sensor is arranged horizontally.

[0010] Optionally, the bracket assembly includes a fixed plate, two diagonal braces and a fixing rod. The two diagonal braces are arranged parallel to each other. The lower ends of the two diagonal braces are connected to the fixed plate, and the upper ends of the two diagonal braces extend obliquely upward. The fixing rod is connected between the upper ends of the two diagonal braces, and an extension plate is connected to the upper end of each diagonal brace.

[0011] Optionally, a movable groove is formed in the lower middle part of the bracing plate, and an extension plate extends in the opposite direction from the upper end of the bracing plate to the lower part of the movable groove. The support rod can slide along the extension plate within the length range of the movable groove.

[0012] Optionally, the steel strip trimming evenness measuring tool also includes a width adjustment component, which includes a guide rail, a slide bar, and a limiting post. The guide rail is fixedly installed and has a guide groove. The slide bar is slidably inserted into the guide groove. Several threaded holes are formed on the guide rail above the guide groove. The limiting post is screwed into the threaded hole and can operably abut against the slide bar. One end of the slide bar is fixedly connected to the lower end of the bracket assembly.

[0013] Optionally, the steel strip trimming evenness measuring tool also includes a mounting frame, which includes a base plate and a U-shaped frame. The base plate is fixedly mounted on the guide rail, and the U-shaped open end of the U-shaped frame is fixedly connected to the base plate. Several strip-shaped holes are formed in the middle of the U-shaped frame.

[0014] Optionally, the track assembly also includes an extended folding plate, one end of which is fixedly connected to a support rod, and the other end of which is fixedly connected to a support shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This application discloses a steel strip trimming evenness measuring tool that can accurately measure the evenness of the trimmed steel strip. It is fixedly supported by a bracket assembly. The track assembly includes a support rod and multiple support shafts arranged vertically at intervals along it. Each support shaft has a grooved wheel connected to its end. The groove on the wheel abuts against the edge of the steel strip, ensuring the steel strip remains stable during measurement. One end of a connecting rod in the sensing assembly is fixedly connected to the bracket assembly, and the other end is connected to the tail end of a horizontally arranged displacement sensor. The head end of the displacement sensor is fixed to the support rod. If the edge of the steel strip is damaged, too wide, or too narrow, the contact position between the grooved wheel and the edge of the steel strip will change. By monitoring the displacement change of the displacement sensor, the evenness of the steel strip edge trimming can be accurately reflected, thereby achieving precise detection of the steel strip trimming quality.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Example 1

[0025] Combination Figures 1-3As shown, an embodiment of this utility model discloses a steel strip trimming evenness measuring tool, comprising a support assembly 1, a track assembly 2, and a sensing assembly 3. The lower end of the support assembly 1 is fixed, and an extension plate 5 is formed at the upper end of the support assembly 1. The track assembly 2 includes a support rod 6, multiple support shafts 7, and multiple grooved wheels 8. The support rod 6 is arranged along the moving direction of the steel strip, and the multiple support shafts 7 are arranged vertically at intervals on the support rod 6. Each grooved wheel 8 is coaxially rotatably connected to the upper end of the corresponding support shaft 7, and the groove on the grooved wheel 8 is used to connect the edge of the steel strip. A horizontally arranged groove perpendicular to the moving direction of the steel strip is formed on the support rod 6, and the extension plate 5 can be slidably inserted into the groove. The track assembly 2 also includes an extension folding plate 20, one end of which is fixedly connected to the support rod 6, and the other end of which is fixedly connected to the support shaft 7. By using extension folding plates 20 of different specifications, the position and height of the grooved wheels 8 can be adjusted. The sensing component 3 includes a connecting rod 9 and a displacement sensor 10. One end of the connecting rod 9 is fixedly connected to the support component 1, and the other end of the connecting rod 9 is fixedly connected to the tail end of the displacement sensor 10. The head end of the displacement sensor is fixedly connected to the support rod 6, and the displacement sensor 10 is arranged horizontally. This steel strip trimming evenness measuring tool can accurately measure the evenness of the steel strip after trimming. It is fixedly supported by the support component 1, and the groove on the grooved wheel 8 can abut against the edge of the steel strip to ensure that the steel strip remains stable during the measurement process. One end of the connecting rod 9 in the sensing component 3 is fixedly connected to the support component 1, and the other end is connected to the tail end of the horizontally arranged displacement sensor 10. The head end of the displacement sensor 10 is fixed to the support rod 6. Once the edge of the steel strip is damaged, too wide or too narrow, the contact position between the grooved wheel 8 and the edge of the steel strip will change. At this time, by monitoring the displacement change of the displacement sensor 10, the trimming evenness of the steel strip edge can be accurately reflected, thereby realizing the accurate detection of the trimming quality of the steel strip.

[0026] In other words, the trimming tool in this embodiment can be set according to the actual situation of the steel strip's cut edge. For example, if only one side of the steel strip is trimmed at a time, only one tool can be set up, fixed on the trimmed side of the steel strip, and the grooved wheel 8 can be brought into contact with the trimmed edge of the steel strip. Of course, if both sides of the steel strip are trimmed, then two steel strip trimming evenness measuring tools can be set up opposite each other, such as... Figure 4 As shown, two steel strip trimming evenness measuring tools are installed on both sides of the steel strip, which can simultaneously abut against both sides of the steel strip, thus allowing simultaneous inspection of both sides of the steel strip to ensure the flatness of both sides of the steel strip.

[0027] Furthermore, the support assembly 1 in this embodiment includes a fixed plate 11, two diagonal braces 12, and a fixing rod 13. The two diagonal braces 12 are arranged parallel to each other, with their lower ends connected to the fixed plate 11 and their upper ends extending obliquely upwards. The fixing rod 13 connects the upper ends of the two diagonal braces 12, and each diagonal brace 12 has an extension plate 5 connected to its upper end. The two parallel diagonal braces 12 and the fixing rod 13 connecting the upper ends of the diagonal braces 12 achieve a stable structure. The lower ends of the diagonal braces 12 are connected to the fixed plate 11, and their upper ends extend obliquely upwards. The extension plates 5 provide more installation space, and the paired extension plates 5 ensure the smooth sliding of the support rod 6 on the extension plates 5. The overall structure of the support assembly 1 saves materials and improves the stability of the support.

[0028] Furthermore, in this embodiment, a movable groove 14 is formed in the lower middle part of the inclined support plate 12, and the extension plate 5 extends in the opposite direction from the upper end of the inclined support plate 12 to the lower part of the movable groove 14. The support rod 6 can slide along the extension plate 5 within the length range of the movable groove 14. This arrangement ensures that when measuring the edge uniformity of the steel strip, if the steel strip is uneven, it will cause the track assembly 2 to slide back and forth on the extension plate 5, while the support rod 6 moves within the length range of the movable groove 14. It can be limited by the combined movement of the movable groove 14 and the extension plate 5, avoiding excessive displacement of the entire track assembly 2, or even damage to the steel strip due to external forces.

[0029] Furthermore, the steel strip trimming evenness measuring tool in this embodiment also includes a width adjustment component 4. The width adjustment component 4 includes a guide rail 15, a slider 16, and a limiting post. The guide rail 15 is fixedly installed and has a guide groove. The slider 16 is slidably inserted into the guide groove. Several threaded holes are formed on the guide rail 15 corresponding to the top of the guide groove. The limiting post is screwed into the threaded holes and can operably abut against the slider 16. One end of the slider 16 is fixedly connected to the lower end of the support assembly 1. That is to say, when it is necessary to simultaneously detect the evenness of both sides of the steel strip, since different steel strips have different widths, the width adjustment component 4 can adjust the position of the entire support assembly 1, track assembly 2, and sensing assembly 3 to adapt to steel strips of different widths.

[0030] Furthermore, the steel strip trimming evenness measuring tool in this embodiment also includes a mounting frame 17. The mounting frame 17 includes a base plate 18 and a U-shaped frame 19. The base plate 18 is fixedly mounted on the guide rail 15, and the U-shaped open end of the U-shaped frame 19 is fixedly connected to the base plate 18. Several strip-shaped holes are formed in the middle of the U-shaped frame 19. The mounting frame 17 can be securely connected to external fixing components. When the installation position is limited in the steel strip detection environment and the guide rail 15 cannot be directly fixed, the entire tool can be fixed by fixing the mounting frame 17. In addition, the mounting frame 17 can also protect the travel of the support assembly 1 and the sensing assembly 3 to avoid external interference.
