Description

Technical Field

[0001] This utility model relates to the field of stainless steel plate production technology, specifically to a testing device for stainless steel plate production with a straightening structure. Background Technology

[0002] Stainless steel plates have a smooth surface and high plasticity, toughness, and mechanical strength. They are resistant to corrosion from acidic and alkaline gases, solutions, and other media. It is an alloy steel that does not easily rust, but it is not absolutely rust-free. Stainless steel plates refer to steel plates that are resistant to corrosion from weak media such as atmosphere, steam, and water, while acid-resistant steel plates refer to steel plates that are resistant to corrosion from chemically corrosive media such as acids, alkalis, and salts.

[0003] The utility model patent application with publication number CN215812098U includes a support platform. A limiting cover is fixedly connected to one side of the top of the support platform, and a material plate is movably sleeved inside the limiting cover. By setting up a testing box, when it is necessary to test the toughness of the material, the material is placed directly above the testing box and a rotary motor is started. The rotary motor drives a threaded rod downward through gears, causing the downward-moving threaded rod to squeeze the material inside the testing box. This allows the testing box to gradually compress the shape of the material. When the material undergoes irreversible deformation, the rotary motor is turned off. The toughness of the material is then calculated by measuring the downward movement of the threaded rod. This avoids the time-consuming and laborious problem of manually testing the toughness of the material, thus bringing convenience to the toughness testing of the material.

[0004] In the aforementioned patents or prior art, the curvature of stainless steel sheets needs to be tested during the production process. However, when the sheet is uneven, ultrasonic probes or laser sensors cannot stably contact the surface, leading to thickness measurement errors or missed defects. Furthermore, separate straightening equipment is required, increasing handling and debugging time, interrupting the production line continuity, and requiring re-straightening and secondary testing after the initial inspection, which extends the production cycle. After straightening, the sheet may deform again during handling, causing the test results to fail to reflect the final state. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for the production of stainless steel plates with a straightening structure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a testing device for stainless steel plate production with a straightening structure, comprising a testing device body equipped with a stainless steel plate body, a laser sensor body installed on the testing device body, a clamping and stretching mechanism provided on one side of the stainless steel plate body, a straightening component provided on the testing device body, and a laser sensor body installed on the testing device body located on the lower side of the stainless steel plate body.

A central brush strip is arranged between the set of first oblique brush strips and the set of second oblique brush strips, and the central brush strip is fixedly connected to the cleaning rod.

[0009] Furthermore, the straightening assembly includes a lower straightening roller rotatably connected to the main body of the detection equipment, the laser sensor body is located between two lower straightening rollers, and the three upper straightening rollers are equidistantly distributed.

[0010] Furthermore, the two lower straight rollers are symmetrically arranged about the body of the testing equipment, the three upper straight rollers are located above the two lower straight rollers, the three upper straight rollers and the two lower straight rollers are staggered, and the stainless steel plate body is located between the three upper straight rollers and the two lower straight rollers.

[0011] Furthermore, both ends of the upper straightening roller are fixedly provided with rotating shafts, and the rotating shafts are connected to the straightening seat through bearings. The end of the sector gear is fixedly connected to the rotating shaft on the upper straightening roller.

[0012] Furthermore, the two rack bodies are symmetrically arranged about the sector gear, and the inside of the spiral bar has a hollow groove.

[0013] Furthermore, each of the straightening seats is provided with a movable hole that matches the cleaning rod, and a set of first inclined brush strips and a set of second inclined brush strips are symmetrically arranged about the center brush strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the testing equipment for stainless steel plate production with a straightening structure is reasonable and has the following advantages:

[0015] (1) This utility model activates the hydraulic rod and the laser sensor body, then clamps the stretching mechanism, and with the cooperation of the straightening component, it can simultaneously straighten the stainless steel plate body while detecting the curvature of the stainless steel plate body. Real-time straightening ensures that the plate remains flat during the test, avoids poor contact of the ultrasonic probe or laser reflection angle deviation caused by bending, reduces thickness measurement error and defect misjudgment, and the flat plate can avoid image stretching or distortion in the laser sensor test, improve the recognition accuracy of small defects such as cracks and pits. At the same time, the integrated design replaces independent testing and straightening equipment, saves equipment purchase costs and factory space occupation, and the energy consumption of a single equipment is lower, and reduces the maintenance complexity of multiple equipment and spare parts inventory pressure.

[0016] (2) By activating the clamping and stretching mechanism, the present invention can make a set of first inclined brush strips, a set of second inclined brush strips and the center brush strip move back and forth under the cooperation of the straightening component and the cleaning component. This can clean the dust and debris generated during the straightening process of the stainless steel plate body, and prevent the problem of scratches and pits on the surface of the stainless steel plate body caused by debris entering the gap between the upper straightening roller and the stainless steel plate body. If the metal debris or oxide dust generated during the straightening process adheres to the surface of the plate, it may block the laser sensor body, resulting in missed detection of defects such as scratches and pits. Simultaneous cleaning can ensure a clean detection environment and more accurate data. In addition, dust entering the straightening roller or transmission component will accelerate wear, resulting in uneven straightening pressure and roller offset. Real-time cleaning can extend the equipment life and maintain the straightening accuracy. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-6 The technical solution provided by this utility model is as follows:

[0028] Example 1:

[0029] In this embodiment, a testing device for stainless steel plate production with a straightening structure includes a testing device body 1 equipped with a stainless steel plate body 12, a laser sensor body 11 installed on the testing device body 1, a clamping and stretching mechanism 13 provided on one side of the stainless steel plate body 12, a straightening component 2 provided on the testing device body 1, and a laser sensor body 11 installed on the testing device body 1 located below the stainless steel plate body 12.

[0030] The straightening assembly 2 includes two hydraulic rods 22 installed on the main body 1 of the testing equipment. Each hydraulic rod 22 has a straightening seat 23 fixedly installed at its output end. The two straightening seats 23 are equipped with a cleaning assembly 3. Three upper straightening rollers 24 are rotatably connected between the two straightening seats 23.

[0031] The cleaning assembly 3 includes a sector gear 31 rotatably connected to the straightening seat 23. The end of the sector gear 31 is fixedly connected to the upper straightening roller 24. A spiral strip 32 is slidably arranged on the straightening seat 23. Two rack bodies 321 are fixedly arranged on the inner wall of the spiral strip 32, and both rack bodies 321 mesh with the sector gear 31. A transmission rod 33 is rotatably arranged on one side of the spiral strip 32. A cleaning rod 34 is rotatably connected to the end of the transmission rod 33. The cleaning rod 34 is slidably connected to the two straightening seats 23. A set of first inclined brush strips 35 is fixedly arranged on the arc-shaped outer wall of the cleaning rod 34. A set of second inclined brush strips 36 is fixedly arranged on the arc-shaped outer wall of the cleaning rod 34. A central brush strip 37 is arranged between the set of first inclined brush strips 35 and the set of second inclined brush strips 36, and the central brush strip 37 is fixedly connected to the cleaning rod 34.

[0032] The straightening assembly 2 includes a lower straightening roller 21 that is rotatably connected to the detection equipment body 1, a laser sensor body 11 located between two lower straightening rollers 21, and three upper straightening rollers 24 that are equidistantly distributed.

[0033] Two lower straight rollers 21 are symmetrically arranged about the main body 1 of the testing equipment, and three upper straight rollers 24 are located above the two lower straight rollers 21. The three upper straight rollers 24 and the two lower straight rollers 21 are staggered, and the stainless steel plate body 12 is located between the three upper straight rollers 24 and the two lower straight rollers 21.

[0034] Both ends of the upper straight roller 24 are fixedly equipped with rotating shafts, and the rotating shafts are connected to the straightening seat 23 through bearings. The end of the sector gear 31 is fixedly connected to the rotating shaft on the upper straight roller 24.

[0035] Two rack bodies 321 are symmetrically arranged about the sector gear 31, and hollow grooves are opened inside the spiral bar 32;

[0036] Each straightening seat 23 is provided with a movable hole that matches the cleaning rod 34. A set of first inclined brush strips 35 and a set of second inclined brush strips 36 are symmetrically arranged about the center brush strip 37.

[0037] When it is necessary to detect the curvature of the stainless steel plate body 12, the stainless steel plate body 12 can be inserted between three upper straightening rollers 24 and two lower straightening rollers 21, and the clamping and stretching mechanism 13 can clamp one end of the stainless steel plate body 12. At this time, by activating the hydraulic rod 22, the two straightening seats 23 are lowered simultaneously, and the arc-shaped outer wall of the three upper straightening rollers 24 is pressed tightly against the top of the stainless steel plate body 12. Then, by activating the clamping and stretching mechanism 13, the stainless steel plate body 12 is pulled. During this process, the laser sensor body 11 can detect the curvature of the lower surface of the stainless steel plate body 12. At the same time, under the pressure of the three upper straightening rollers 24 and the lower straightening rollers 21, the surface of the stainless steel plate body 12 can gradually become straighter, thereby achieving the purpose of straightening the stainless steel plate body 12. Furthermore, during the straightening process of the stainless steel plate body 12, the upper straightening roller 24 can rotate. Simultaneously, under the connection of the rotating shaft, when the sector gear 31 rotates, it can drive the spiral strip 32 to slide back and forth through the meshing of two rack bodies 321 fixed to the inner wall of the spiral strip 32. At the same time, it can drive the transmission rod 33, which is rotatably connected to the spiral strip 32, to rotate around the position connected to the cleaning rod 34. This allows the cleaning rod 34 to slide back and forth between the two straightening seats 23, and simultaneously drive a set of first inclined brush strips 35, a set of second inclined brush strips 36, and a center brush strip 37 to move back and forth. This can clean the dust and debris generated after the stainless steel plate body 12 is straightened, preventing the problem of scratches and pits on the surface of the stainless steel plate body 12 from occurring due to debris entering the gap between the upper straightening roller 24 and the stainless steel plate body 12.

[0038] Working principle: When detecting the curvature of the stainless steel plate body 12, the stainless steel plate body 12 is inserted between three upper straightening rollers 24 and two lower straightening rollers 21, and the clamping and stretching mechanism 13 clamps one end of the stainless steel plate body 12. At this time, by activating the hydraulic rod 22, the two straightening seats 23 are lowered simultaneously, and the arc-shaped outer wall of the three upper straightening rollers 24 is pressed tightly against the top of the stainless steel plate body 12. Then, by activating the clamping and stretching mechanism 13, the stainless steel plate body 12 is pulled. During this process, the laser sensor body 11 can detect the curvature of the lower surface of the stainless steel plate body 12. At the same time, under the pressure of the three upper straightening rollers 24 and the lower straightening rollers 21, the stainless steel plate body 12 can be straightened. 2. The surface gradually becomes flat, and during the straightening process of the stainless steel plate body 12, the upper straightening roller 24 can rotate. At the same time, under the connection of the rotating shaft, the sector gear 31 rotatably connected to the straightening seat 23 can rotate. Since the sector gear 31 can mesh with the two rack bodies 321 fixed to the inner wall of the spiral strip 32, the spiral strip 32 can be driven to slide back and forth. At the same time, the transmission rod 33 rotatably connected to the spiral strip 32 can be driven to rotate around the position connected to the cleaning rod 34. The cleaning rod 34 can slide back and forth between the two straightening seats 23, and at the same time, a set of first inclined brush strips 35, a set of second inclined brush strips 36 and the center brush strip 37 can be moved back and forth to clean the dust and debris generated after the stainless steel plate body 12 is straightened.
