Description

Technical Field

[0001] This invention belongs to the field of steel strip inspection technology, specifically relating to a defect detection device for steel strips. Background Technology

[0002] Steel strip is a strip-shaped product based on carbon steel. As an important industrial material, steel strip is widely used in automobiles, construction, and home appliances. During the production process of steel strip, high-strength steel wires are incorporated into the strip, enabling it to withstand strong tensile forces. However, due to factors such as raw materials, process parameters, and equipment conditions, defects such as cracks, scratches, holes, and inclusions can easily occur. These defects not only affect the appearance quality of the steel strip but may also reduce its mechanical properties and even lead to product failure. Therefore, it is necessary to inspect the steel strip during the production process to prevent defects such as dents and scratches from appearing on the surface after packaging, which could affect subsequent use.

[0003] For example, Chinese patent CN221078451U describes a steel strip surface inspection device. This device uses a combination of a transmitting and receiving light module to detect the bottom surface of the steel strip by utilizing reflected light. The combination of an imaging module and an inkjet module allows operators to first perform a preliminary inspection of problematic areas on the steel strip surface, and then further inspect the specific location of the processed steel strip based on the inkjet marks, thereby improving accuracy. Existing steel strip inspection devices only inspect the surface of the steel strip and cannot detect potential defects and flaws inside the steel strip, such as cracks or fracture tendencies. Furthermore, they cannot detect the deformation and recovery ability of the steel strip, making it impossible to ensure that the steel strip will not break during use. Utility Model Content

[0004] The purpose of this invention is to provide a defect detection device for steel strips, which can apply pressure to both the upper and lower surfaces of the steel strip, thereby causing the steel strip to deform and effectively detect the deformation and recovery of the steel strip. Simultaneously, it can detect internal defects in the steel strip and effectively detect whether breakage will occur during the deformation process.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A defect detection device for steel strip includes a support frame, the support frame including a base plate and a support plate fixed above the base plate, the support plate having an adjustment groove and a sliding groove, and a presser being mounted on the side of the support plate away from the sliding groove.

[0007] An adjustment mechanism includes an adjustment push rod, which is fixedly connected to the top of the base plate, and the output end of the adjustment push rod is fixedly connected to the bottom of one end of an adjustment block. The adjustment block is slidably connected to the adjustment groove, and the other end of the adjustment block is slidably connected to a pressure roller assembly.

[0008] A sliding mechanism includes a pneumatic rod, which is fixedly connected to one side of the support plate. The output end of the pneumatic rod is fixedly connected to one end of a sliding block. The sliding block is slidably connected to the sliding groove, and the other end of the sliding block is equipped with a clamping assembly.

[0009] Furthermore, the adjustment mechanism also includes a guide rod, the two ends of which are fixedly connected to the upper and lower sides of the adjustment groove, and the guide rod is slidably connected to the adjustment block.

[0010] Furthermore, the pressure roller assembly includes a lower pressure roller and an upper pressure roller. The lower pressure roller is fixedly connected to the lower end of the adjusting block, and the upper pressure roller is fixedly connected to the upper end of the adjusting block. The other end of the upper pressure roller is rotatably connected to one end of the limiting plate, and the other end of the limiting plate is slidably connected to the other end of the lower pressure roller.

[0011] Furthermore, the sliding mechanism also includes a guide rod, which is fixed in the sliding groove, and the sliding block is slidably connected to the guide rod.

[0012] Furthermore, the clamping assembly includes a fixing plate, which is fixedly connected to the sliding block. A sliding rod is fixed above one end of the fixing plate near the sliding block, and a support cylinder is rotatably connected to the other end of the fixing plate away from the sliding block.

[0013] Furthermore, the clamping assembly also includes a clamping plate, which is disposed above the fixed plate, and an adjusting screw is fixed to the bottom of the clamping plate. The adjusting screw is threadedly connected to the support cylinder, and the clamping plate is slidably connected to the sliding rod.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses a defect detection device for steel strips. By applying force to the surface of the steel strip, it ensures that the steel strip deforms, thereby detecting potential defects and flaws inside the steel strip, such as cracks or fracture tendencies. It can quickly detect defects in the steel strip, improving detection efficiency and allowing for more intuitive identification of potential problems, reducing the missed detection rate. Simultaneously, the reaction of the steel strip under stress can be observed during the detection process, enabling assessment of its quality and reliability.

[0016] This utility model discloses a defect detection device for steel strips. Through the cooperation of a sliding mechanism and an adjusting mechanism, when the steel strip is deformed by applied force, the sliding mechanism is quickly energized, ensuring that the steel strip can be reset when no power is applied. By observing whether the steel strip can completely reset, it can be determined whether there is permanent deformation or internal defect. Simultaneously, it reduces manual intervention and improves detection efficiency. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1 to 5 As shown, a defect detection device for steel strip includes a support frame 10. The support frame 10 includes a base plate 11 and a support plate 12 fixed above the base plate 11. The support plate 12 is provided with an adjustment groove 121 and a sliding groove 122, and a pressing plate is assembled on the side of the support plate 12 away from the sliding groove 122.

[0026] The adjustment mechanism 20 includes an adjustment push rod 21, which is fixedly connected to the top of the base plate 11. The output end of the adjustment push rod 21 is fixedly connected to the bottom of one end of the adjustment block 22. The adjustment block 22 is slidably connected to the adjustment groove 121, and the other end of the adjustment block 22 is slidably connected to the pressure roller assembly 23.

[0027] The sliding mechanism 30 includes a pneumatic rod 31, which is fixedly connected to one side of the support plate 12. The output end of the pneumatic rod 31 is fixedly connected to one end of the sliding block 32. The sliding block 32 is slidably connected to the sliding groove 122, and the other end of the sliding block 32 is equipped with a clamping assembly 33.

[0028] It should be noted that the pressing plate is driven by a pneumatic cylinder (this is a conventional technology and will not be elaborated further). Anti-slip textures are provided on the pressing plate to effectively press and fix the steel strip, ensuring its stability during inspection. When defect inspection of the steel strip is required, one end of the steel strip is fixed by the pressing plate, and then the steel strip is sequentially placed into the pressure roller assembly 23 and fixed using the clamping assembly 33. The adjusting push rod 21 moves the adjusting block 22 and the pressure roller assembly 23, simultaneously applying pressure to the top or bottom of the steel strip, causing it to deform. Since the pressing plate is fixedly connected to the support plate 12, when the pressure roller assembly 23 moves and the steel strip deforms, it effectively drives the pressure roller assembly 23 and the adjusting block 22 to slide within the adjusting groove 121. At the same time, when the adjusting block 22 moves, the pneumatic rod 31 is inflated, so that the pneumatic rod 31 can accumulate power. When the pressure roller assembly 23 is reset, it ensures that the steel belt is reset synchronously. At the same time, it can effectively detect whether there are cracks in the steel belt and whether the deformation has been recovered.

[0029] Preferably, the adjusting mechanism 20 further includes a guide rod, the two ends of which are fixedly connected to the upper and lower sides of the adjusting groove 121, and the guide rod is slidably connected to the adjusting block 22. The guide rod effectively ensures the movement of the adjusting block 22, allowing it to move smoothly and accurately when driven by the adjusting push rod 21, thus ensuring that the pressure roller assembly 23 precisely applies pressure to the steel strip.

[0030] like Figure 3 , Figure 4 As shown, the pressure roller assembly 23 includes a lower pressure roller 231 and an upper pressure roller 232. The lower pressure roller 231 is fixedly connected to the lower end of the adjusting block 22, and the upper pressure roller 232 is fixedly connected to the upper end of the adjusting block 22. The other end of the upper pressure roller 232 is rotatably connected to one end of the limiting plate 233, and the other end of the limiting plate 233 is slidably connected to the other end of the lower pressure roller 231.

[0031] In this embodiment, when the steel strip is located in the pressure roller assembly 23, by rotating the limiting plate 233 in the upper pressure roller 232, it is slidably connected to one end of the lower pressure roller 231, which can effectively protect the steel strip and prevent it from shifting or misaligning when pressure is applied, thus preventing the detection process from being ineffective. Simultaneously, the limiting plate 233...

[0032] Preferably, the sliding mechanism 30 further includes a guide rod fixed in the sliding groove 122, and the guide rod is slidably connected to the sliding block 32. The guide rod can effectively guide the movement of the sliding block 32, ensuring that when the sliding block 32 is moved by the power transmission of the steel belt, it can smoothly inflate and store energy in the pneumatic rod 31.

[0033] like Figure 4 , Figure 5 As shown, the clamping assembly 33 includes a fixing plate 331, which is fixedly connected to the sliding block 32, and the interior of the fixing plate 331 near and away from the sliding block 32 is rotatably connected to a support cylinder 332.

[0034] Preferably, the clamping assembly 33 further includes a clamping plate 333, which is disposed above the fixing plate 331, and a plurality of adjusting screws 334 are fixed at the bottom of the clamping plate 333, and the plurality of adjusting screws 334 are respectively threadedly connected to the support cylinder 332.

[0035] In this embodiment, it should be noted that the fixing plate 331 is used to support the steel strip. By fixing it to the sliding block 32, it ensures that when the clamping assembly 33 is driven by the deformation of the steel strip, it can effectively drive the sliding block 32 and charge it with air through the pneumatic rod 31. The support cylinder 332 is rotatably connected inside the fixing plate 331, effectively engaging with the adjusting screw 334 at the bottom of the clamping plate 333. When it is necessary to fix the steel strip, the clamping plate 333 is slidably connected to the sliding rod on the fixing plate 331, and the adjusting screw 334 is threadedly connected to the support cylinder 332. By rotating the support cylinder 332, it engages with the adjusting screw 334, thereby causing the clamping plate 333 to be pressed against the fixing plate 331, thus fixing the steel strip.

[0036] The working principle of this utility model is as follows: When steel strip needs to be inspected, the steel strip is placed on the pressing plate and fixed by the pressing plate. Simultaneously, the steel strip is placed between the upper pressure roller 232 and the lower pressure roller 231. Then, the limiting plate 233 is rotated, causing the limiting plate 233 to slide and connect with the lower pressure roller 231, preventing the steel strip from shifting during movement. Furthermore, by placing the steel strip above the fixing plate 331, the adjusting screw 334 at the bottom of the clamping plate 333 is threadedly connected to the support cylinder 332 on the fixing plate 331. By rotating the support cylinder 332, the support cylinder 332 and the adjusting screw 334 engage in threaded action, thereby causing the clamping plate 333 to engage with the fixing plate 331, fixing the other end of the steel strip. When the adjusting push rod 21 is activated, it drives the adjusting block 22, which is fixedly connected to its output end, to slide along the guide rod in the adjusting groove 121. Simultaneously, the adjusting block 22 drives the pressure roller assembly 23 to move. The pressure roller assembly 23 applies pressure to both the upper and lower surfaces of the steel strip, causing it to deform. This deformation applies force to both sides. Since the pressing plate is fixedly connected to the support plate 12, and the clamping assembly 33 is slidably connected to the sliding groove 122 on the support plate 12 via the sliding block 32, the clamping assembly 33 and the sliding block 32 are effectively moved, simultaneously inflating and storing energy in the pneumatic rod 31. When the adjusting push rod 21 resets the adjusting block 22, the pneumatic rod 31 outputs power, which in turn resets the sliding block 32 and the clamping assembly 33. During the deformation process, the deformation capacity of the steel strip can be accurately detected, and whether cracks have occurred in the steel strip can be precisely detected.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
