Description

Technical Field

[0001] This utility model belongs to the technical field of continuous annealing production equipment for cold-rolled strip steel. Specifically, this utility model relates to a structure for preventing strip steel from being scratched in a welding machine. Background Technology

[0002] In the strip steel production process, especially in the welding stage of strip steel such as silicon steel where surface quality requirements are extremely high, the surface condition of the strip steel directly affects the product grade and performance. In actual operation, the strip steel support structure of traditional welding machines often uses bakelite boards for the guide plates. These boards have a high coefficient of friction, poor wear resistance, and lack elasticity. When in contact with the strip steel, the hard friction easily causes scratches or bright lines on the lower surface of the strip steel. Traditional guide plates are mostly integral structures, which are prone to thermal expansion and deformation due to temperature changes during long-term use. Uneven contact between the deformed guide plate and the strip steel not only increases frictional damage but may also cause scratches on the strip steel edges due to localized stress concentration.

[0003] Chinese patent (publication number: 201353583Y) discloses a steel strip side guide device at the inlet and outlet of a welding machine, which belongs to auxiliary equipment in the steel rolling process of the metallurgical industry. It includes a base, characterized by an arc-shaped guide plate on the base and baffles on both sides of the guide plate. However, this guide plate is prone to scratching the steel strip. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a welding machine anti-stripping structure that reduces steel strip scratches and facilitates guide plate replacement. To achieve the above objective, the technical solution adopted by this utility model is as follows: a welding machine anti-stripping structure, including a base, a bottom plate on the base, a guide plate structure on the bottom plate, and an adjustment structure on the base.

[0005] The guide plate structure includes a first guide plate and a second guide plate. The first guide plate is disposed at both ends of the base plate, and the second guide plate is disposed on the base plate. Both the first guide plate and the second guide plate are integrally formed MC nylon sheets.

[0006] The adjustment structure includes an adjustment plate, which is disposed at both ends of the base plate. An adjustment screw is provided on the adjustment plate, and the adjustment screw abuts against the base plate.

[0007] The first guide plate, the second guide plate, and the base plate are all uniformly provided with threaded holes.

[0008] The base plate is a one-piece stainless steel structure.

[0009] The base includes a support plate, which is evenly spaced at the bottom of the base plate.

[0010] Both the first guide plate and the second guide plate have anti-scratch bevels on both sides.

[0011] The adjustment plate is an L-shaped plate.

[0012] The technical advantages of this invention are as follows: Both the first guide plate and the second guide plate are made of MC nylon, which has the characteristics of low friction coefficient, high wear resistance and certain elasticity. This can fundamentally prevent the strip steel from being scratched by hard metal. The first guide plate and the second guide plate use MC nylon instead of the original bakelite board. Furthermore, the surfaces of the first guide plate and the second guide plate can be processed to be smooth to reduce friction and reduce scratches and bright lines on the lower surface of the silicon steel. The guide plate structure is set in a split manner, with the first guide plate and the second guide plate spaced apart. This can effectively prevent the defects of thermal expansion and deformation of the first guide plate and the second guide plate. The segmented distribution of the first guide plate and the second guide plate can reduce costs by partially replacing them after scratches. Attached Figure Description

[0016] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0017] like Figure 1 As shown, a structure for preventing strip steel scratches in a welding machine includes a base 1, a base plate 2 mounted on the base 1, a guide plate structure 3 mounted on the base plate 2, and an adjustment structure 4 mounted on the base 1. Multiple bases 1 are provided, spaced apart at the bottom of the base plate 2. The bases 1 support and fix the base plate 2. The base plate 2 is a flat plate, and the guide plate structure 3 is connected to the base plate 2. When the strip steel is placed on the guide plate structure 3, compared to the original structure, it can reduce strip steel wear, decrease batch scratches, and reduce product degradation.

[0018] The guide plate structure 3 includes a first guide plate 301 and a second guide plate 302. The first guide plate 301 is disposed at both ends of the base plate 2, and the second guide plate 302 is disposed in pairs on the base plate 2. Both the first guide plate 301 and the second guide plate 302 are integrally formed structures of MC nylon sheets. The first guide plate 301 and the second guide plate 302 are both made of MC nylon sheets, which have the characteristics of low friction coefficient, high wear resistance and certain elasticity, and can fundamentally prevent the strip steel from being scratched by hard metals. The first guide plate 301 and the second guide plate 302 use MC nylon sheets instead of the original bakelite sheets, and the surfaces of the first guide plate 301 and the second guide plate 302 are processed to reduce friction and reduce scratches and bright lines on the lower surface of silicon steel. The guide plate structure 3 is set in a split manner, with the first guide plate 301 and the second guide plate 302 set alternately, which can effectively prevent the defects of thermal expansion deformation of the first guide plate 301 and the second guide plate 302. The segmented distribution of the first guide plate 301 and the second guide plate 302 can reduce costs by partially replacing them after scratches. The lengths of the first guide plate 301 and the second guide plate 302 can be adjusted according to actual conditions, making them convenient to use. When a single guide plate 301 or the second guide plate 302 is damaged, only that part needs to be replaced, reducing costs.

[0019] The adjustment structure 4 includes an adjustment plate 401, which is located at both ends of the base plate 2. Adjustment screws 402 are mounted on the adjustment plate 401 and abut against the base plate 2. The adjustment plate 401, with its adjustment screws 402, provides a fine-tuning function for the base plate 2. Simultaneously, the adjustment screws 402 firmly hold the base plate 2 against the base 1. When fine-tuning the base plate 2, the adjustment screws 402 on both sides can be adjusted. Rotating one adjustment screw 402 in one direction and the other in the opposite direction fine-tunes the relative position of the guide plates, ensuring that the strip always runs within the central area of ​​the first guide plate 301 and the second guide plate 302. This reduces the risk of scratches from edge contact and makes the installation of the guide plate's base plate more convenient.

[0020] The first guide plate 301, the second guide plate 302, and the base plate 2 are all evenly provided with threaded holes 5. The base plate 2 is fixed to the first guide plate 301 and the second guide plate 302 by bolts, which makes the guide plates less prone to deformation and easier to disassemble during later maintenance. All bolts used are of national standard size and national standard spare parts, which improves maintenance efficiency. The first guide plate 301 and the second guide plate 302 are stably fixed to the base plate 2.

[0021] The base plate 2 is a one-piece stainless steel structure. This one-piece stainless steel structure provides high strength, high wear resistance, and corrosion resistance, enabling it to withstand the indirect pressure and environmental impacts of the strip during operation, thus enhancing the structural rigidity of the base plate 2.

[0022] The base 1 includes support plates 101, which are evenly spaced at the bottom of the base plate 2. The evenly spaced support plates 101 provide stable support for the base plate 2, forming a stable support frame. The support plates 101 are forged from high-strength alloy steel, possessing excellent load-bearing capacity and deformation resistance, and can withstand the combined pressure generated by the base plate 2, guide plate structure 3, and the strip during operation for extended periods. The height of the support plates 101 is precisely calculated to ensure height matching between the base plate 2 and the welding machine's conveyor path, allowing the strip to smoothly transition onto the guide plate structure 3 when entering and leaving the welding machine, avoiding strip vibration or increased friction due to height differences.

[0023] Both sides of the first guide plate 301 and the second guide plate 302 are provided with anti-scratch bevels 6. These bevels on both sides of the first guide plate 301 and the second guide plate 302 smoothly transition the right angles at their edges into bevels. When the strip deviates slightly during operation, the bevels prevent the strip edge from making hard contact with the guide plate at the right angle, reducing the risk of scratches through a smooth transition and further enhancing the anti-scratch effect.

[0024] The adjusting plate 401 is an L-shaped plate. One side of the adjusting plate 401 is connected to the base 1, and the other side is connected to the adjusting screw 402. By setting the adjusting plate 401 to an L-shaped structure, a cavity is formed between the adjusting plate 401 and the base 1, which can reduce the resistance when rotating the adjusting screw 402 and facilitate fine adjustment of the base plate 2.

[0025] The role and effect of the embodiments

[0026] Both the first guide plate 301 and the second guide plate 302 are made of MC nylon, which has the characteristics of low friction coefficient, high wear resistance and certain elasticity. It can fundamentally prevent the strip steel from being scratched by hard metal. The first guide plate 301 and the second guide plate 302 use MC nylon plates instead of the original bakelite boards. The surfaces of the first guide plate 301 and the second guide plate 302 can be processed to reduce friction and reduce scratches and bright lines on the lower surface of silicon steel. The guide plate structure 3 is set in a split manner, with the first guide plate 301 and the second guide plate 302 set at intervals. This can effectively prevent the defects of thermal expansion deformation of the first guide plate 301 and the second guide plate 302. The segmented distribution of the first guide plate 301 and the second guide plate 302 can reduce costs by partially replacing them after scratches.

[0027] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
