Description

Technical Field

[0001] The invention belongs to the technical field of straightening roller replacement, and specifically relates to an auxiliary replacement device for wide and thick plate straightening rollers. Background Art

[0002] Straightening rollers are key components used in metal processing to correct the straightness and flatness of materials such as plates, strips, bars or tubes. They are widely used in industries such as steel rolling, aluminum processing, and machinery manufacturing. By applying reverse pressure, the warping, wavy edges, bending and other defects generated by the material during rolling, transportation or heat treatment are corrected to ensure that the surface of the material is flat and the internal stress of the material is evenly distributed to meet the accuracy requirements of subsequent cutting, stamping and other processing or direct use, reducing the risk of subsequent deformation.

[0003] At present, after the production of wide and thick plates, in order to ensure their normal use, they need to be straightened by straightening rollers. During the use of straightening rollers, according to the thickness of the wide and thick plates, different sizes of straightening rollers need to be replaced, and the inner diameters of straightening rollers of different sizes are also different. Therefore, when replacing the straightening rollers, the rotating shaft inside the straightening rollers needs to be replaced at the same time, which increases the workload and is not conducive to improving work efficiency. In order to deal with the above problems and defects, a wide and thick plate straightening roller auxiliary replacement device is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to provide an auxiliary replacement device for wide and thick plate straightening rollers in response to the above-mentioned defects, so as to solve the limitation problem that when replacing straightening rollers of different sizes and different inner diameters according to the different thicknesses of wide and thick plates, it is necessary to replace the internal rotating shaft of the straightening roller at the same time, which increases the workload and is not conducive to improving work efficiency.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] An auxiliary replacement device for wide and thick plate straightening rollers comprises: a straightening mechanism installed in a straightening machine, and a replacement component and a tensioning component installed in the straightening mechanism; the tensioning component comprises a positioning plate, the outer wall of the positioning plate is fixedly equipped with a motor I, the end of the output shaft of the motor I is fixedly equipped with a rotating shaft, an inner cavity is opened inside the rotating shaft, the inner wall of the inner cavity is fixedly equipped with a motor II, the end of the output shaft of the motor II is fixedly equipped with a screw, the outer wall of the screw is threadedly connected with a moving ring, the outer wall of the moving ring is rotatably connected with a connecting rod, and the end of the connecting rod away from the moving ring is rotatably connected to an annular plate; the outer wall of the rotating shaft is fixedly equipped with a fixing ring, the outer wall of the fixing ring is rotatably connected with a rotating rod, and the end of the rotating rod away from the fixing ring is rotatably connected to the bottom of the annular plate.

[0007] The motor II drives the screw to rotate, and the rotation of the screw drives the moving ring to move horizontally. The movement of the moving ring drives the connecting rod to rotate, and then drives the annular plate to move longitudinally. Since the fixed ring is fixedly connected to the rotating shaft, the rotating rod is driven to rotate during the movement of the annular plate. The movement of the annular plate is limited by the rotating rod, which is conducive to adjusting the diameter of the rotating shaft according to the straightening rollers of different aperture sizes.

[0008] Preferably, the replacement component includes a connecting plate rotatably connected to the rotating shaft, the outer wall of the connecting plate is provided with a groove, the inner wall of the groove is clamped with a clamping plate, both sides of the clamping plate are threadedly connected with fixing bolts, and the fixing bolts pass through the side walls of the clamping plate, the ends of the fixing bolts are threadedly connected to the connecting plate, and both sides of the positioning plate are rotatably connected with fixing plates.

[0009] Preferably, a positioning hole is provided at the bottom of the groove, a positioning pin is clamped on the inner wall of the positioning hole, and the top of the positioning pin is fixedly connected to the bottom of the card plate. By providing the positioning hole and the positioning pin, it is beneficial to improve the tightness and stability of the connection between the card plate and the connecting plate, and ensure the limiting effect of the rotating shaft.

[0010] Preferably, the outer wall of the annular plate is provided with a fixing groove, and the inner wall of the fixing groove is fixedly equipped with an anti-skid pad, which is beneficial to improve the friction between the annular plate and the inner wall of the straightening roller, thereby improving the fixing effect of the straightening roller.

[0011] Preferably, a baffle is fixedly mounted on one side of the annular plate close to the positioning plate, and the shape of the baffle matches the annular plate. The baffle is provided to help limit the position of the straightening roller and ensure that the straightening roller is installed in a suitable position.

[0012] Preferably, the number of the connecting rods, annular plates and rotating rods is four groups, and the four groups of connecting rods, annular plates and rotating rods are evenly distributed around the rotating shaft. By limiting the number and position of the connecting rods, annular plates and rotating rods, it is beneficial to improve the positioning effect of the straightening roller and ensure the normal use of the device.

[0013] Preferably, the connecting rod and the rotating rod are oriented in opposite directions, and the connecting rod and the rotating rod rotate in opposite directions. By limiting the connecting rod and the rotating rod, it is beneficial to improve the stability of the annular plate when moving.

[0014] Beneficial effects of the present invention: Compared with the prior art, the wide and thick plate straightening roller auxiliary replacement device described in the present invention drives the screw to rotate through the motor II, and the rotation of the screw drives the moving ring to move laterally, and the movement of the moving ring drives the connecting rod to rotate, thereby driving the annular plate to move longitudinally. Since the fixed ring is fixedly connected to the rotating shaft, the rotating rod is driven to rotate during the movement of the annular plate, and the movement of the annular plate is limited by the rotating rod, which is beneficial to adjusting the diameter of the rotating shaft according to straightening rollers of different aperture sizes. At the same time, it can also improve the tightness of the connection between the device and the straightening roller, which is beneficial to improving the convenience of replacing the straightening roller and ensuring the normal straightening operation of the device on the wide and thick plates.

[0015] By turning the fixing bolt, remove the fixing bolt, then take the clamping plate out of the groove to cancel the limitation on the rotating shaft, and then shrink the annular plate through the tensioning assembly to separate the annular plate from the inner wall of the straightening roller, and then turn the positioning plate to adjust the rotating shaft to a suitable angle, remove the straightening roller, install a new straightening roller, and repeat the above steps to reset the clamping plate and re-limit the rotating shaft, which is conducive to improving the convenience of replacing the straightening roller, reducing the workload of the staff and improving their production efficiency.

[0024] like Figure 1 , Figure 3 and Figure 5 As shown, the auxiliary replacement device for wide and thick plate straightening rollers comprises: a straightening mechanism 1 installed in the straightening machine, and a replacement component 2 and a tensioning component 3 installed in the straightening mechanism 1; the tensioning component 3 comprises a positioning plate 301, the outer wall of the positioning plate 301 is fixedly equipped with a motor I302 that provides a driving force, the end of the output shaft of the motor I302 is fixedly equipped with a rotating shaft 303, the interior of the rotating shaft 303 is provided with an inner cavity 304, the inner wall of the inner cavity 304 is fixedly equipped with a motor II305 that provides a driving force, the end of the output shaft of the motor II305 is fixedly equipped with a screw rod 306, the outer wall of the screw rod 306 is threadedly connected with a moving ring 307, and the outer wall of the moving ring 307 is rotatably connected with A connecting rod 308, one end of the connecting rod 308 away from the movable ring 307 is rotatably connected to an annular plate 309; an outer wall of the rotating shaft 303 is fixedly equipped with a fixed ring 310, and an outer wall of the fixed ring 310 is rotatably connected to a rotating rod 311, and one end of the rotating rod 311 away from the fixed ring 310 is rotatably connected to the bottom of the annular plate 309. There are four groups of connecting rods 308, annular plates 309 and rotating rods 311, and the four groups of connecting rods 308, annular plates 309 and rotating rods 311 are evenly distributed on the circumferential side of the rotating shaft 303. By limiting the number and position of the connecting rods 308, annular plates 309 and rotating rods 311, it is beneficial to improve the positioning effect of the straightening roller and ensure the normal use of the device.

[0025] like Figure 2 and Figure 4As shown, the replacement component 2 includes a connecting plate 201 rotatably connected to the rotating shaft 303, the outer wall of the connecting plate 201 is provided with a groove 202, the inner wall of the groove 202 is clamped with a clamping plate 203, both sides of the clamping plate 203 are threadedly connected with fixing bolts 204, and the fixing bolts 204 penetrate the side walls of the clamping plate 203, the ends of the fixing bolts 204 are threadedly connected to the connecting plate 201, and both sides of the positioning plate 301 are rotatably connected with fixing plates 205, by rotating the fixing bolts 204, the fixing bolts 204 are removed, and then The clamping plate 203 is taken out from the groove 202, thereby canceling the limitation on the rotating shaft 303, and then the annular plate 309 is contracted by the tensioning component 3 to separate the annular plate 309 from the inner wall of the straightening roller, and then the positioning plate 301 is rotated to adjust the rotating shaft 303 to a suitable angle, and the straightening roller is removed and a new straightening roller is installed. Finally, the above steps are repeated to reset the clamping plate 203 and re-limit the rotating shaft 303, which will help improve the convenience of replacing the straightening roller, reduce the workload of the staff, and improve their production efficiency.

[0026] like Figure 2 and Figure 4 As shown, a positioning hole 206 is provided at the bottom of the groove 202, and a positioning pin 207 is clamped on the inner wall of the positioning hole 206. The top of the positioning pin 207 is fixedly connected to the bottom of the clamping plate 203.
