The output shaft of the motor is provided with a bidirectional lead screw. Movable blocks are provided on the outer walls of both the front and rear ends of the bidirectional lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through its adjustable mechanism, allows the equipment to be flexibly adjusted according to the different lengths of the pressure rollers, eliminating the need to remove the steel rollers from the equipment. This greatly simplifies the loading and unloading process, reduces the working time of the staff, and improves work efficiency. Specifically, the motor drives the bidirectional lead screw to rotate, which in turn moves the movable block along the axial direction of the bidirectional lead screw. This, in turn, drives the guide rod to slide in the guide groove through the base plate and guide block, achieving precise adjustment of the mounting plate position. This allows it to adapt to pressure rollers of different lengths. This design not only solves the inconvenience of traditional steel roller position fine adjustment structures during use but also improves the quality of roll forming. 2. This utility model, through its adjustable mechanism, enables the equipment to precisely position the upper roller according to the pressing requirements of different specifications, effectively improving the forming accuracy. During operation, rotating the rotating block drives the nut to rotate. Due to the threaded connection between the screw and the nut, and the rotating connection between the screw and the lifting plate, and the vertical guidance achieved by the sliding block and the sliding groove of the lifting plate, the up-and-down movement of the screw drives the linear up-and-down movement of the lifting plate, thereby adjusting the height of the upper roller. At the same time, the threaded engagement between the threaded column and the adjusting ring allows the two adjusting rings to move axially along the threaded column, thereby adjusting the horizontal position of the upper roller and ensuring that the gap between the upper and lower rollers is uniform, thus guaranteeing the quality stability of roll forming. This dual adjustment mechanism allows the equipment to quickly adjust to the optimal pressing state when dealing with metal sheets of different thicknesses and materials, enhancing the versatility and practicality of the equipment.

[0017] Please see Figure 1 and Figure 4 This utility model provides a technical solution: a steel roller position fine adjustment structure, including a base plate 1, two mounting blocks 2 are provided on both the front and rear ends of the base plate 1, guide grooves 3 are provided on both the left and right sides of the top of the base plate 1, an adjustment mechanism 4 is detachably connected to the base plate 1, two vertical mounting plates 5 are tightly attached to the front and rear sides of the top of the base plate 1, and sliding grooves 6 are provided on both the left and right sides of the top of the two mounting plates 5. Two adjustment mechanisms 7 are bolted between the tops of the two mounting plates 5, and the adjustment mechanisms 7 are arranged inside the two corresponding sliding grooves 6.

Two lower rollers 9 are rotatably connected to the bottom between the two sides of the two mounting plates 5, and the two ends of the lower rollers 9 rotatably extend through the mounting plates 5 to the outside and are each fitted with an end cap 10.

[0018] In use, mounting blocks 2 are fixedly installed on both the front and rear sides of the base plate 1 for stable installation and fixation of the overall structure; guide grooves 3 are also provided on both sides of the top of the base plate 1, and the rear end of the base plate 1 is detachably connected to the adjustment mechanism 4 for easy subsequent maintenance and adjustment; the top of the base plate 1 is tightly fitted with the mounting plate 5, and the top left and right sides of the mounting plate 5 are provided with sliding grooves 6 to guide and limit the slider 76; the top of the two mounting plates 5 are connected to the adjustment mechanism 7 by bolts to realize flexible control and fine adjustment functions; the bottom of the middle between the two sides of the two mounting plates 5 is rotatably connected to the guide shaft 8 to ensure smooth and coordinated movement; the bottom of the two sides of the two mounting plates 5 is rotatably connected to the lower roller 9, and the two ends of the lower roller 9 are fitted with end caps 10 to effectively prevent external impurities from entering and improve the service life of the components.

[0019] Preferably, one end of each of the four mounting blocks 2 is fixedly connected to the front and rear ends of the base plate 1, which further enhances the stability and reliability of the overall structure.

[0020] Please see Figure 2 To quickly adjust the position of the two mounting plates 5 on the base plate 1, the adjustment mechanism 4 includes a motor 41. The front end of the motor 41 is bolted to the rear end of the base plate 1 to ensure the stability of the overall structure. The output shaft of the motor 41 is equipped with a bidirectional lead screw 42, which is rotatably located inside the middle of the base plate 1. Movable blocks 43 are provided on the outer walls of both the front and rear ends of the bidirectional lead screw 42. A base plate 44 is fixed to the top of each movable block 43. The tops of the two base plates 44 are respectively fixed to the bottoms of the two mounting plates 5, and the bottoms of the two base plates 44 are slidably located on the top surface of the base plate 1. Guide blocks 45 are fixed to the left and right sides of the bottom of the base plates 44. Guide holes 46 are opened through the interior of the guide blocks 45. Guide rods 47 are slidably connected between the interiors of the two corresponding guide holes 46. The inner walls of the guide holes 46 and the guide rods 47 are slidably connected, thereby providing a stable movement trajectory for the movable blocks 43. By driving the bidirectional lead screw 42 to rotate by the motor 41, the position of the two mounting plates 5 can be quickly and smoothly adjusted.

[0021] Preferably, the output shaft of the motor 41 is connected to one end of the bidirectional lead screw 42, and the outer wall of the bidirectional lead screw 42 is threadedly connected to the inner wall of the movable block 43. The bidirectional lead screw 42 is driven to rotate by the forward and reverse rotation of the motor 41, thereby driving the movable block 43 to move along the base plate 1 under the action of the bidirectional lead screw 42. At the same time, the guide block 45 moves linearly along the direction of the guide rod 47. The guide rod 47 is set inside the corresponding guide groove 3, and the two ends of the guide rod 47 are fixed to the front and rear sides of the inner wall of the guide groove 3, respectively, to ensure the rigidity and accuracy of the guiding structure. A storage groove for accommodating the bidirectional lead screw 42 is opened in the top center of the base plate 1, and the movable block 43 is slidably set in the storage groove.

[0022] Please see Figure 3 To quickly fix the upper roller pressure roller 79 to the appropriate position on the threaded column 77, the adjusting mechanism 7 includes two top seats 71. The two top seats 71 are respectively located above the tops of the two corresponding sliding grooves 6. The bottoms of the two top seats 71 are respectively bolted to the tops of the two mounting plates 5, ensuring the stability of the overall structure. Each top seat 71 is provided with a rotating block 72 at its top, and a nut 73 is provided at the top of the rotating block 72. A screw 74 is threadedly connected to the inner wall of the nut 73. A lifting plate 75 is rotatably connected to the bottom of the screw 74. A slider 76 is bolted to the bottom of the lifting plate 75. The slider 76 is positioned on the opposite side. The sliding connection within the groove 6 consists of two symmetrically arranged sliders 76, one at the front and one at the back. A threaded column 77 is rotatably connected between the two sliders 76 on their closest sides via a bearing, allowing the threaded column 77 to rotate smoothly. Threads are machined on both sides of the outer wall of the threaded column 77, and adjusting rings 78 are threadedly connected to both the front and rear sides of its outer wall. An upper roller 79 is fitted into the middle of the outer wall of the threaded column 77. Rotating the adjusting rings 78 allows for fine adjustment of the axial position of the upper roller 79 on the threaded column 77, thus adjusting and fixing the position of the upper roller 79. The upper roller 79 and its corresponding lower roller 9 are vertically distributed. This adjustment mechanism 7 improves operational convenience and positioning accuracy.

[0023] Preferably, the top of the top seat 71 is rotatably connected to the bottom of the rotating block 72, allowing the rotating block 72 to rotate relative to the top seat 71. Rotating the rotating block 72 drives the screw 74 to rise and fall. The top of the rotating block 72 is welded to the top of the nut 73 to ensure reliable force transmission. The bottom of the screw 74 passes through the rotating block 72 and the top seat 71 in sequence and is rotatably connected to the top of the lifting plate 75. The outer wall of the screw 74 is threaded to match the inner wall of the nut 73. Rotating the screw 74 drives the lifting plate 75 and the upper roller 79 to achieve smooth lifting and lowering movements, thereby completing the rapid adjustment and fixation of the position.

[0024] Working principle: First, the entire structure is stably fixed in the required position by the mounting blocks 2 on both the front and rear ends of the base plate 1. The cooperation between the guide groove 3 and the guide rod 47 ensures the accuracy of the movement of the adjustment mechanism 4 and the adjustment mechanism 7. When it is necessary to adjust the position of the mounting plate 5 longitudinally, the motor 41 is started. The output shaft of the motor 41 drives the bidirectional lead screw 42 to rotate. Since the bidirectional lead screw 42 is threadedly connected to the movable block 43, the two movable blocks 43 will move towards or away from each other on the bidirectional lead screw 42. The movable blocks 43 drive the base plate 44 to move. The guide blocks 45 on both sides of the bottom of the base plate 44 slide along the guide rod 47 to ensure the smooth movement of the mounting plate 5. The movement of the base plate 44 drives the mounting plate 5 to adjust its position on the base plate 1 until the mounting plate 5 reaches the appropriate position. When the position of the upper roller 79 needs to be adjusted, the rotating block 72 is rotated. Because the screw 74 is threadedly connected to the nut 73, and the bottom of the screw 74 is rotatably connected to the lifting plate 75, the rotating block 72 will drive the screw 74 to move the lifting plate 75 up and down. The lifting plate 75 will drive the slider 76 to move, and the slider 76 will drive the threaded column 77 to move, thereby driving the upper roller 79 to move up and down. At the same time, by rotating the adjusting rings 78 on the front and rear sides of the outer wall of the threaded column 77, since the adjusting rings 78 are threadedly connected to the threaded column 77, the rotation of the adjusting rings 78 will cause them to move back and forth on the threaded column 77. This allows for fine adjustment of the position of the upper roller 79 in the axial direction of the threaded column 77, quickly and accurately fixing the upper roller 79 in the appropriate position on the threaded column 77 to meet different working requirements. The entire steel roller position fine adjustment structure achieves rapid and precise adjustment of the steel roller position through the coordinated work of the adjusting mechanism 4 and the adjusting mechanism 7, improving work efficiency and forming quality. In this steel roller position fine-tuning structure, the cooperation of the adjustment mechanism 4 and the adjustment mechanism 7 not only simplifies the tedious disassembly and assembly steps in the traditional steel roller position adjustment process, but also improves the accuracy and efficiency of the adjustment. In actual operation, the operator only needs to control the motor 41 to drive the adjustment mechanism 4 according to the molding requirements to achieve rapid longitudinal positioning of the mounting plate 5 and all its components. At the same time, by using the screw 74 and nut 73 in the adjustment mechanism 7, and the fine adjustment of the axial position of the upper roller 79 by the adjustment ring 78, the precise adjustment of the upper roller 79 in three-dimensional space can be easily completed. This setting not only reduces the time and labor intensity of manual operation, but also avoids the errors that may be introduced by repeated disassembly and assembly of steel rollers, thereby ensuring the high uniformity of the centering and height position during the roll forming process, effectively improving the quality stability of the formed product. In addition, it can also adapt to pressure rollers and forming molds of different lengths and specifications. The above is the working process of the entire device, and the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
