Description

Technical Field

[0001] This utility model relates to the field of strip cutting technology, specifically a strip cutting guide device. Background Technology

[0002] With the rapid development of global manufacturing, cold-rolled strip steel, as an important industrial base material, faces increasingly higher requirements for quality and performance. Significant progress has been made both domestically and internationally in edge trimming technology. Domestic enterprises such as Baosteel and Ansteel have continuously optimized their processes and improved edge trimming quality by introducing, digesting, and absorbing advanced technologies. Meanwhile, some research institutes and universities have also conducted in-depth research in the field of edge trimming technology and achieved a number of innovative results. Internationally, developed countries such as Europe and the United States are in a leading position in cold-rolled strip steel edge trimming technology, possessing advanced equipment and technology, and are able to produce high-quality, high-precision cold-rolled strip steel products.

[0003] However, compared with developed countries, my country's cold-rolled strip edge trimming process still lags behind, mainly in terms of uneven edges, numerous burrs, and poor dimensional accuracy. These problems not only affect the aesthetics and performance of the products but also reduce their market competitiveness. Therefore, improving the quality of cold-rolled strip edge trimming has become an important trend and urgent need for the current industry development. Utility Model Content

[0004] The purpose of this invention is to provide a strip cutting edge guiding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a strip steel cutting edge guiding device, comprising a fixed base and a strip steel, wherein a guiding mechanism is provided on the fixed base;

[0006] The guiding mechanism includes a fixed frame fixedly connected to the top surface of the fixed base. A motor is fixedly connected to the inner wall of the fixed frame. A bidirectional threaded rod is fixedly connected to the output end of the motor through a coupling. The bidirectional threaded rod rotatably passes through the fixed base. Two internal threaded blocks are threadedly connected to the outer wall of the bidirectional threaded rod. The two internal threaded blocks are symmetrically arranged about the fixed base as the central axis. A connecting plate is fixedly connected to the outer wall of each of the two internal threaded blocks.

[0007] Preferably, two fixing plates are fixedly connected to the front side of the fixing base, and a sliding rod is fixedly connected to the side of each fixing plate that is far apart from each other.

[0008] Preferably, the two slide rods pass through the two connecting plates respectively, and the two slide rods are slidably connected to the two connecting plates respectively.

[0009] Preferably, hinge rods are rotatably connected to the left and right sides of the two connecting plates, and fixing blocks are fixedly connected to the left and right sides of the two connecting plates. Limiting rods pass through the four fixing blocks, and the four limiting rods are fixedly connected to the four fixing blocks respectively.

[0010] Preferably, each of the four hinge rods has a sliding groove on its outer wall, and the four limiting rods are slidably connected to the inner wall of the four sliding grooves respectively.

[0011] Preferably, each of the four hinge rods has a groove, and the inner wall of each of the four grooves is provided with two telescopic rods. The outer rods of several telescopic rods are fixedly connected to the inner walls of the four grooves, and the inner rods of several telescopic rods slide to the outside of the hinge rods.

[0012] Preferably, the inner rods of the plurality of telescopic rods are fixedly connected to a connecting frame, and the inner wall of the connecting frame is rotatably connected to a pressure roller. The outer walls of the inner rods of the plurality of telescopic rods are all wound with springs. One end of the spring is fixedly connected to a hinge rod, and the other end of the spring is fixedly connected to the connecting frame. The outer walls of the plurality of pressure rollers are in contact with the top and bottom surfaces of the strip steel, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a guiding mechanism, when the drive motor drives the bidirectional threaded rod to rotate, the two connecting plates move closer or further apart with the cooperation of the two internal threaded blocks, the sliding rod and the fixing plate. When the two connecting plates move closer, they will drive the hinge rod to move, so that the sliding groove on the hinge rod slides on the outer wall of the limiting rod, so that the upper hinge rod and the lower hinge rod move closer to each other. This allows the pressure roller on the hinge rod to fit against the top and bottom surfaces of the strip steel to position the strip steel. When the pressure roller and the strip steel are tightly fitted, the spring and the telescopic rod cooperate with each other, and the spring is compressed to prevent the pressure roller and the strip steel from being damaged due to excessive contact force. The cooperation of multiple guiding mechanisms can ensure that the strip steel maintains a stable tension state during the edge cutting process, reduce edge cutting defects caused by tension fluctuations, improve the edge cutting quality of cold-rolled strip steel, and reduce problems such as uneven edge cutting, many burrs, and poor dimensional accuracy.

[0021] The guiding mechanism 2 includes a fixed frame 21 fixedly connected to the top surface of the fixed base 1. A motor 22 is fixedly connected to the inner wall of the fixed frame 21. The output end of the motor 22 is fixedly connected to a bidirectional threaded rod 23 via a coupling. The bidirectional threaded rod 23 rotatably passes through the fixed base 1. Two internal threaded blocks 24 are threadedly connected to the outer wall of the bidirectional threaded rod 23. The two internal threaded blocks 24 are symmetrically arranged about the fixed base 1 as the central axis. A connecting plate 25 is fixedly connected to the outer wall of each of the two internal threaded blocks 24. Two fixed plates 26 are fixedly connected to the front side of the fixed base 1. A sliding rod 27 is fixedly connected to the two fixed plates 26 on their opposite sides. Slide rods 27 pass through two connecting plates 25 respectively, and the two slide rods 27 are slidably connected to the two connecting plates 25 respectively. Hinges 28 are rotatably connected to the left and right sides of the two connecting plates 25. Fixing blocks 29 are fixedly connected to the left and right sides of the two connecting plates 25. Limiting rods 291 pass through each of the four fixing blocks 29, and the four limiting rods 291 are fixedly connected to the four fixing blocks 29 respectively. Slide grooves 292 are formed on the outer walls of the four hinge rods 28, and the four limiting rods 291 are slidably connected to the inner walls of the four slide grooves 292 respectively. Grooves 281 are formed on the four hinge rods 28, and the inner walls of the four grooves 281 are... Each wall is equipped with two telescopic rods 293. The outer rods of several telescopic rods 293 are fixedly connected to the inner walls of the four grooves 281. The inner rods of several telescopic rods 293 slide to the outside of the hinge rod 28. The inner rods of several telescopic rods 293 are fixedly connected to a connecting frame 294. The inner wall of the connecting frame 294 is rotatably connected to a pressure roller 295. The outer wall of the inner rods of several telescopic rods 293 is wound with a spring 296. One end of the spring 296 is fixedly connected to the hinge rod 28, and the other end of the spring 296 is fixedly connected to the connecting frame 294. The outer walls of several pressure rollers 295 are in contact with the top and bottom surfaces of the strip steel 3. By providing a guide mechanism 2, the pressure roller 295 on the hinge rod 28 is positioned against the top and bottom surfaces of the strip steel 3. When the pressure roller 295 is tightly pressed against the strip steel 3, the spring 296 and the telescopic rod 293 cooperate with each other, and the spring 296 is compressed to prevent the pressure roller 295 from being too pressed against the strip steel 3 and causing damage to the strip steel 3.

When the two connecting plates 25 move closer together, they will drive the hinge rod 28 to move, causing the slide groove 292 on the hinge rod 28 to slide on the outer wall of the limiting rod 291, so that the upper hinge rod 28 and the lower hinge rod 28 move closer together, thereby causing the pressure on the hinge rod 28 to... Roller 295 is attached to the top and bottom surfaces of strip 3 to position strip 3. When roller 295 is tightly attached to strip 3, spring 296 and telescopic rod 293 cooperate with each other. Spring 296 is compressed to prevent excessive force between roller 295 and strip 3 from damaging strip 3. Multiple guide mechanisms 2 cooperate with each other to ensure that strip 3 maintains a stable tension state during edge cutting, reduce edge cutting defects caused by tension fluctuations, improve the edge cutting quality of strip 3, and reduce problems such as uneven edge cutting, many burrs, and poor dimensional accuracy of strip 3.
