Description
Technical Field
[0001] This utility model relates to the field of steel strips, and in particular to a tool steel strip drawing device. Background Technology
[0002] In the production and processing of tool steel strips, tension straightening is a crucial process to ensure strip quality. Its purpose is to eliminate residual stress and correct shape defects such as waviness, warping, and lateral bending, thereby improving the straightness and surface quality of the strip. However, traditional tension straightening equipment suffers from inconvenient roller spacing adjustment, often relying on manual or simple mechanical methods. This not only results in low adjustment efficiency but also difficulty in guaranteeing accuracy, making it impossible to quickly adapt to the tension straightening needs of steel strips of varying thicknesses. Consequently, production efficiency is low, and product quality is inconsistent.
[0003] Therefore, it is necessary to provide a new tool steel strip drawing device to solve the above-mentioned technical problems. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, a tool steel strip drawing device is provided to solve the above problems.
[0005] The tool steel strip straightening device provided by this utility model includes: two mounting plates; the two mounting plates are arranged opposite each other, and the four corners of the relatively close side of the two mounting plates are connected by connecting plates; wherein, a straightening component capable of adjusting the distance is provided on the relatively close side of the two mounting plates, so as to adjust according to the steel strip of different thicknesses; both ends of the relatively close side of the two mounting plates are equipped with guide components, and the steel strip can be guided and conveyed by the guide components.
[0006] Preferably, the tension straightening assembly includes two upper tension straightening rollers and two lower tension straightening rollers, which are arranged in an alternating manner. Each of the two mounting plates has two guide grooves for sliding the upper tension straightening rollers and the lower tension straightening rollers. Both ends of the two upper tension straightening rollers and the two lower tension straightening rollers are slidably connected to the guide grooves through mounting seats.
[0007] Preferably, the tension straightening assembly further includes a bidirectional screw mounted on one side of one of the mounting plates. Both outer ends of the bidirectional screw are threadedly connected to threaded blocks. The two sides of the upper threaded block are connected to the mounting seats at one end of the two upper tension straightening rollers via connecting rods. The two sides of the lower threaded block are connected to the mounting seats at one end of the two lower tension straightening rollers via connecting rods. A first motor for driving the bidirectional screw to rotate is mounted on the top of one side of the mounting plate.
[0008] Preferably, a guide rod is installed on one side of the other mounting plate, and guide blocks are slidably connected to the outer ends of the guide rod. Both sides of the upper guide block are connected to the mounting seats at one end of the two upward straightening rollers through connecting rods, and both sides of the lower guide block are connected to the mounting seats at one end of the two downward straightening rollers through connecting rods.
[0009] Preferably, the guiding assembly includes an upper guide roller and a lower guide roller, with the upper guide roller located above the lower guide roller. Both mounting plates are provided with sliding grooves for the upper guide roller to slide. Both ends of the upper guide roller pass through the sliding grooves via mounting seats and are connected to lifting blocks.

[0010] Preferably, both ends of the lower guide roller are rotatably connected to the mounting plate, and a second motor for driving the lower guide roller to rotate is installed on one side of one of the mounting plates.
[0011] Compared with related technologies, the tool steel strip drawing device provided by this utility model has the following beneficial effects:
[0012] The tension straightening assembly of this invention uses a first motor to drive a bidirectional screw, which moves the threaded block to achieve precise and rapid adjustment of the distance between the upper and lower tension straightening rollers. Whether the steel strip is thin or thick, the tension straightening rollers can maintain a suitable distance. In conjunction with the staggered tension straightening rollers, uniform tension and bending forces are applied to the steel strip, effectively eliminating various shape defects of the steel strip, greatly improving the tension straightening accuracy and efficiency, and ensuring the straightness and surface quality of the steel strip.
[0013] In the guiding assembly of this utility model, an electric push rod drives a lifting block, which can flexibly adjust the height of the upper guide roller so that the distance between it and the lower guide roller can adapt to steel strips of different thicknesses. The upper and lower guide rollers work together to clamp and guide the steel strip from top to bottom. At the same time, the lower guide roller rotates actively under the drive of a second motor to provide power for the steel strip conveying, ensuring that the steel strip runs smoothly along the predetermined path during the conveying process, effectively preventing deviation and twisting, improving the reliability and flexibility of the guide, and ensuring the smooth progress of the straightening process.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0020] This utility model provides a tool steel strip straightening device, which includes: two mounting plates 1; the two mounting plates 1 are arranged opposite each other, and the four corners of the relatively close side of the two mounting plates 1 are connected by connecting plates; wherein, a straightening component capable of adjusting the distance is provided on the relatively close side of the two mounting plates 1, so as to adjust according to the steel strip of different thicknesses; both ends of the relatively close side of the two mounting plates 1 are equipped with guide components, and the steel strip can be guided and conveyed by the guide components.
[0021] It should be noted that there are two mounting plates 1, arranged opposite each other, forming the basic frame of the entire steel strip straightening equipment. Their four corners, located on opposite sides, are connected by connecting plates to form a stable frame structure, providing mounting carriers and support for other components such as the straightening assembly and guide assembly. The straightening assembly, located on the opposite side of the two mounting plates 1, is the core component for achieving the steel strip straightening function. It can adjust the distance according to steel strips of different thicknesses, adapting to the straightening requirements of steel strips of different specifications by adjusting the spacing between the straightening rollers. During the straightening process, the straightening assembly applies tension and bending force to the steel strip, causing it to undergo elasto-plastic deformation, thereby eliminating shape defects such as waviness and warping, and improving the straightness and surface quality of the steel strip. The guide assembly is installed at both ends of the opposite side of the two mounting plates 1. Its main function is to guide and transport the steel strip, guiding it to run smoothly along a predetermined path and preventing deviation or twisting during transport.
[0022] In this embodiment of the present invention, the tension straightening assembly includes two upper tension straightening rollers 2 and two lower tension straightening rollers 21, which are arranged in an alternating pattern. Two guide grooves 22 are provided on each of the two mounting plates 1 for sliding of the upper tension straightening rollers 2 and lower tension straightening rollers 21. Both ends of the two upper tension straightening rollers 2 and the two lower tension straightening rollers 21 are slidably connected to the guide grooves 22 via mounting seats. The tension straightening assembly also includes a bidirectional screw 23 mounted on one side of one of the mounting plates 1. Threaded blocks 24 are threaded to both outer ends of the bidirectional screw 23. The upper threaded blocks 24 are connected to the screws on both sides via connecting blocks. The connecting rod is connected to the mounting base at one end of the two upper straightening rollers 2. Both sides of the lower threaded block 24 are connected to the mounting base at one end of the two lower straightening rollers 21 via connecting rods. A first motor for driving the bidirectional screw 23 to rotate is installed on the top of one side of the mounting plate 1. A guide rod 25 is installed on one side of the other mounting plate 1. Guide blocks 26 are slidably connected to the outer ends of the guide rod 25. Both sides of the upper guide block 26 are connected to the mounting base at one end of the two upper straightening rollers 2 via connecting rods. Both sides of the lower guide block 26 are connected to the mounting base at one end of the two lower straightening rollers 21 via connecting rods.
[0023] It should be noted that there are two upper straightening rollers 2, arranged alternately with two lower straightening rollers 21, which are the key actuators that directly act on the steel strip for straightening. During the straightening process, the upper straightening rollers 2 and lower straightening rollers 21 cooperate to apply bending and tension forces to the steel strip. Through contact and relative movement with the surface of the steel strip, the steel strip undergoes elastoplastic deformation, thereby correcting shape defects. The lower straightening rollers 21 bear the weight of the steel strip and the pressure applied by the upper straightening rollers 2, and work together with the upper straightening rollers 2 to deform the steel strip as it passes through the straightening assembly, thus correcting defects such as waviness and warping of the steel strip. The mounting seats at both ends are slidably connected to the guide grooves 22. The guide grooves 22 are formed on the two mounting plates 1, providing a guide track for the sliding of the upper straightening rollers 2 and lower straightening rollers 21. They limit the direction of movement of the straightening rollers, ensuring that the upper straightening rollers 2 and lower straightening rollers 21 can slide smoothly along the vertical direction when adjusting the spacing, without deviation or wobbling. The guide groove 22 cooperates with the mounting seats at both ends of the straightening roller to keep the straightening roller stable during sliding, ensuring the relative positional accuracy between the straightening rollers, thereby improving the accuracy and stability of steel strip straightening. The bidirectional screw 23, mounted on one side of one of the mounting plates 1, is the core transmission component for adjusting the straightening roller spacing. Its outer ends have threads with opposite directions of rotation, threadedly connected to two threaded blocks 24. Driven by the first motor, the bidirectional screw 23 rotates, converting the rotational motion into linear motion of the threaded blocks 24. The movement of the threaded blocks 24 drives the connected upper straightening roller 2 and lower straightening roller 21 to slide synchronously up and down, achieving precise adjustment of the straightening roller spacing. The design of the bidirectional screw 23 ensures that the two straightening roller groups move simultaneously and at equal distances, ensuring uniform force on the steel strip during straightening. The guide rod 25, mounted on the other mounting plate 1, assists in the stable sliding of the straightening rollers and enhances the structural stability of the straightening assembly. The outer ends of the guide rod 25 are slidably connected to the guide block 26, which is connected to the mounting bases of the upper and lower straightening rollers 21 via connecting rods. During the up-and-down sliding of the straightening rollers, the guide rod 25 provides guidance to the guide block 26, sharing the lateral force on the mounting base during sliding. This prevents the straightening rollers from tilting or jamming due to uneven force during spacing adjustments, ensuring smooth and stable movement and improving the reliability of the straightening assembly. The cooperation between the guide block 26 and the guide rod 25 enhances the overall rigidity and stability of the straightening assembly, ensuring reliable operation of the straightening rollers in complex straightening working environments.
[0024] In an embodiment of this utility model, the guiding assembly includes an upper guide roller 3 and a lower guide roller 31, with the upper guide roller 3 located above the lower guide roller 31. Both mounting plates 1 have sliding grooves for the upper guide roller 3 to slide. Both ends of the upper guide roller 3 pass through the sliding grooves via mounting seats and are connected to lifting blocks 32. Electric push rods for driving the lifting blocks 32 to reciprocate are installed on the relatively far sides of the two mounting plates 1. Both ends of the lower guide roller 31 are rotatably connected to the mounting plates 1, and a second motor for driving the lower guide roller 31 to rotate is installed on one side of one of the mounting plates 1.
[0025] It should be noted that the upper guide roller 3, located above the lower guide roller 31, is a key component in the guiding assembly for guiding the steel strip from the top. During the steel strip conveying process, the upper guide roller 3 cooperates with the lower guide roller 31 to clamp and guide the steel strip from both above and below, ensuring that the steel strip is conveyed smoothly along the predetermined path. The lower guide roller 31 is fixedly installed between the two mounting plates 1, with both ends rotatably connected to the mounting plates 1, serving as the lower support and guiding component of the guiding assembly. The lower guide roller 31 provides a stable lower support surface for the steel strip, bearing the weight of the steel strip and the pressure applied by the upper guide roller 3. Working together with the upper guide roller 3, it keeps the steel strip straight during conveying, preventing sagging, twisting, or other phenomena. Sliding grooves are formed on the two mounting plates 1, providing sliding tracks for the mounting base of the upper guide roller 3. It limits the direction of movement of the upper guide roller 3, ensuring that the upper guide roller 3 can only move up and down in the vertical direction, ensuring that the upper guide roller 3 can move precisely up and down when adjusting the distance between itself and the lower guide roller 31, without deviation or wobbling. The lifting block 32 is connected to the mounting seats at both ends of the upper guide roller 3 and reciprocates under the drive of the electric push rod. The lifting block 32 is the key actuator for realizing the height adjustment of the upper guide roller 3, which converts the telescopic movement of the electric push rod into the vertical displacement of the upper guide roller 3.
[0026] The working principle of the tool steel strip straightening device provided by this utility model is as follows: When using the tool steel strip straightening device of this utility model, firstly, according to the thickness of the steel strip to be processed, the first motor on the top side of the mounting plate 1 is started. The first motor drives the bidirectional screw 23 to rotate. Since the threads at both ends of the bidirectional screw 23 rotate in opposite directions, the threaded block 24 connected to the threads at both ends will move linearly along the screw axis. The upper threaded block 24 drives two upper straightening rollers 2 through the connecting rod, and the lower threaded block 24 drives two lower straightening rollers 21 through the connecting rod, which slide up and down synchronously in the guide groove 22, accurately adjusting the distance between the upper and lower straightening rollers to match the thickness of the steel strip. Next, according to the specific condition of the steel strip, the electric push rod on the side of the mounting plate 1 that is relatively far away is started. The electric push rod pushes the lifting block 32 to move back and forth. The lifting block 32 drives the mounting seat of the upper guide roller 3 to slide up and down in the sliding groove, thereby adjusting the distance between the upper guide roller 3 and the lower guide roller 31, so that the upper and lower guide rollers can properly clamp the steel strip. After preparation, the steel strip to be straightened is introduced into the equipment, and the second motor located on one side of one of the mounting plates 1 is started. The second motor drives the lower guide roller 31 to rotate, and the lower guide roller 31 uses the friction between itself and the steel strip to move the steel strip forward. During the conveying process, the upper guide roller 3 and the lower guide roller 31 clamp and guide the steel strip from both above and below, ensuring that the steel strip smoothly enters the straightening assembly along the predetermined path. After the steel strip enters the straightening assembly, the staggered upper straightening roller 2 and lower straightening roller 21 apply tension and bending forces to the steel strip. During the movement of the steel strip, the upper straightening roller 2 and the lower straightening roller 21 cause the steel strip to undergo elastoplastic deformation, thereby eliminating shape defects such as waviness and warping of the steel strip.
