[0031] like Figures 1 to 5As shown, a rolling device for the upper side of a special-shaped steel pipe in an embodiment of the utility model includes a rolling assembly 100, a frame 200, an adjustment seat 300 connected to the frame 200 for sliding up and down, a height adjustment assembly 400 installed on the frame 200 for changing the upper and lower positions of the adjustment seat 300, a swing seat 500 rotatably connected to the adjustment seat 300, and an angle adjustment assembly 600 installed on the adjustment seat 300 for adjusting the swing angle of the swing seat 500. In fact, a rolling device for the upper side of a special-shaped steel pipe in the present invention is installed between the curling process and the welding process of the special-shaped seamed steel pipe production line through a frame 200, so as to roll the upper side of the special-shaped steel pipe with a flat upper side before welding; the height adjustment component 400 can be a single-axis translation table or a hydraulic cylinder, etc., to drive the adjustment seat 300 to move up and down to change the upper and lower positions of the swing seat 500 installed on the adjustment seat 300; the angle adjustment component 600 is one of a servo angle motor, a worm gear and a turbine matching drive component, etc., which can drive the swing seat 500 to change the angle relative to the adjustment seat 300.
[0032] The front side of the swing seat 500 is provided with more than three connecting holes 510 that are equidistantly spaced and distributed in a row. The rolling assembly 100 includes a pressing frame 110 and a pressing roller 120 that is rotatably connected to the pressing frame 110 and is used to connect to the upper side of the special-shaped steel pipe to be formed. The rear side of the pressing frame 110 is provided with two connecting rods 111 that are detachably connected to the two connecting holes 510. In fact, the connecting rods 111 can be detachably connected to the connecting holes 510 by means of threaded connection, snap connection, etc. After the pressing roller 120 is installed on the swing seat 500 through the pressing frame 110, the height and angle of the pressing roller 120 installed on the swing seat 500 can be adjusted by the height adjustment assembly 400 and the angle adjustment assembly 600 to adapt to the upper side of the special-shaped steel pipe with different heights and angles. Figure 2 The swing seat 500 shown in the figure is provided with five connecting holes 510. The distance between the two connecting rods 111 is the same as the distance between the two adjacent connecting holes 510. The position of the roller can be adjusted along the arrangement direction of the connecting holes 510 to adapt to the left and right position changes of the pressing roller 120 due to the angle adjustment, ensuring that the pressing roller 120 can contact the upper side of the special-shaped steel pipe, so as to adapt to more different types of special-shaped steel pipes within a certain range.
[0033] The utility model provides a side rolling device for a special-shaped steel pipe, which cooperates with a rolling assembly 100, a frame 200, an adjustment seat 300, a height adjustment assembly 400, a swing seat 500 and an angle adjustment assembly 600 to adjust the height, angle and left and right position of a pressing roller 120. When the type of the special-shaped steel pipe is changed, there is no need to replace the side rolling device for the special-shaped steel pipe, and the utility model can adapt to more different types of special-shaped steel pipes within a certain range.
[0034] Specifically, the upper side rolling device of the special-shaped steel pipe of the present invention preferably includes two connecting bolts 700. The rear side of the swing seat 500 is provided with a plurality of clearance holes 520 corresponding to the plurality of connection holes 510. The connecting bolts 700 are used to pass through the clearance holes 520 and then be threadedly connected to the connecting rod 111. In fact, if Figure 2 and Figure 3 As shown, the rear side of the connecting rod 111 can be provided with a threaded hole matching the connecting bolt 700, the outer diameter of the stud of the connecting bolt 700 is smaller than the aperture of the clearance hole 520, and the head of the connecting bolt 700 is larger than the aperture of the clearance hole 520. During installation, the connecting rod 111 is first inserted into the connecting hole 510, and then the screw of the connecting bolt 700 passes through the clearance hole 520 and is threadedly connected to the threaded hole on the rear side of the connecting rod 111 in the installation hole, so that the head of the connecting bolt 700 is abutted against the rear side of the swing seat 500, thereby realizing the detachable connection between the connecting rod 111 and the connecting hole 510.
[0035] More specifically, the rear portion of the connecting rod 111 is preferably a frustum with a diameter that gradually decreases from front to back, and the contour of the clearance hole 520 matches the contour of the rear portion of the connecting rod 111. The rear portion of the connecting rod 111 and the clearance hole 520 cooperate with each other, making it easier for the connecting rod 111 to extend into the connecting hole 510. During this process, the connecting hole 510 guides and positions the rear portion of the connecting rod 111, facilitating the subsequent installation of the connecting bolt 700.
[0036] Furthermore, the angle adjustment assembly 600 preferably includes a self-locking worm gear 610 rotatably connected to the adjustment seat 300 and a self-locking worm 620 rotatably connected to the adjustment seat 300 and meshing with the self-locking worm gear 610. The swing seat 500 is fixed to the front side of the self-locking worm gear 610. The self-locking worm gear 620 and the self-locking worm gear 610 cooperate with each other to achieve the self-locking worm gear 620 driving the self-locking worm gear 610 to rotate, while the self-locking worm gear 610 cannot reversely drive the self-locking worm gear 620 to rotate. This prevents the angle of the pressure roller 120 from changing due to other external forces acting on the self-locking worm gear 610, thereby ensuring the stability of the pressure roller 120 during operation. In practice, one end of the self-locking worm gear 620 can be provided with a rotating wheel or one end can be a rectangular parallelepiped, so that the operator can directly drive or rotate the self-locking worm gear 620 using a wrench to adjust the angle of the pressure roller 120.
[0037] It is worth mentioning that Figure 1 and Figure 4As shown, the self-locking worm 620 is preferably located above the worm and its axis is parallel to the horizontal plane. This allows the self-locking worm 620 to be misaligned with the swing seat 500 located in front of the self-locking worm wheel 610, preventing interference between the self-locking worm 620 and the swing seat 500. Furthermore, the self-locking worm wheel 610 is preferably a fan-shaped worm wheel with a missing lower portion, which leaves more space for the special-shaped steel pipe after rolling by the pressure roller 120. This allows the installation position of the pressure roller 120 to be closer to the rotation center of the self-locking worm wheel 610, reducing the amplitude of the left and right deviation of the pressure roller 120 due to angle adjustment.
[0038] It should be noted that the rear side of the swing seat 500 is preferably provided with two fixed rods 530 spaced apart and fixedly connected to the front side of the self-locking worm gear 610. Figure 2 As shown, the fixing rod 530 has a certain length, which leaves a certain installation position for the installation of the connecting bolt 700.
[0039] Specifically, the frame 200 is preferably provided with a gantry 210, the adjustment seat 300 is placed in the gantry 210 and is slidably connected to the left and right sides of the gantry 210 up and down, and an adjustment through hole 211 is provided in the middle of the crossbeam of the gantry 210. The height adjustment assembly 400 preferably includes an adjustment screw passing through the adjustment through hole 211 and the lower end of which is fixed to the upper end of the adjustment seat 300, and two adjustment nuts 420 threadedly connected to the adjustment screw, and the two adjustment nuts 420 are respectively used to abut against the upper and lower sides of the crossbeam of the gantry 210. When the upper and lower positions of the adjustment seat 300 need to be changed, the two adjusting nuts 420 are rotated in opposite directions respectively so that the two adjusting nuts 420 are respectively away from the upper and lower sides of the beam of the gantry 210, and then the adjusting screw is pulled to drive the adjustment seat 300 to move up and down to change its position. Finally, the two adjusting nuts 420 are rotated again until the two adjusting nuts 420 are respectively against the upper and lower sides of the beam of the gantry 210, so that the position of the adjustment seat 300 can be fixed, and the upper and lower positions of the adjustment seat 300 can be adjusted.
[0040] The above are only specific embodiments of the present invention and do not limit the patent scope of the present invention. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present invention.
