Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of heavy plate straightening, and particularly relates to a finishing straightening machine for heavy plates. Background Art
[0002] Heavy plates generally refer to steel plates with relatively large thickness and width, having high strength and toughness. The thickness generally exceeds 10 mm, the width is usually above 1500 mm, and the common length is 6 - 18 meters. They are widely used in heavy industrial fields such as construction, machinery manufacturing, shipbuilding, and electric power.
[0003] The straightening of heavy plates is an important link in the production process of heavy plates, aiming to eliminate plate shape defects (such as warping, waviness, camber, etc.) generated during the rolling, cooling, or heat treatment of the plates, and ensure the flatness and dimensional accuracy of the plates. The straightening of heavy plates is mainly based on the elastic - plastic bending theory. The heavy plate to be straightened is fed into the straightening machine, and the working rolls of the straightening machine alternately bend the plate, applying a certain bending force to cause the plate to generate reverse bending in the elastic - plastic deformation region, making the fiber lengths of all parts of the plate tend to be consistent, thereby achieving straightening and eliminating the original defects.
[0004] Common heavy plate straightening machines include roller straightening machines, press straightening machines, and stretch straightening machines, etc. Among them, the roller straightening machine is the most widely used. The roller straightening machine consists of multiple working rolls arranged vertically and horizontally. When the plate passes through the gap between the working rolls, it is straightened by the repeated bending action. According to the number and arrangement of the rolls, it can be divided into multi - roll straightening machines, skew - roll straightening machines, etc.
[0005] The roller straightening machine usually consists of parts such as the straightening machine body, transmission device, roll - gap adjusting device, guiding device, and control system. The straightening machine body, as the core component, includes the working roll system, backup rolls, etc., and directly performs the straightening operation on the plate. The transmission device provides power for the working rolls to rotate at a certain speed and direction, driving the plate forward. The roll - gap adjusting device can adjust the gap between the working rolls and accurately control the magnitude of the straightening force according to factors such as the thickness and material of the plate. The guiding device guides the plate to accurately enter the straightening machine and prevents the plate from running off - track. The control system realizes the automatic control of the straightening machine.
[0006] Currently, according to different market usage requirements, the thicknesses of heavy plates are also different, and the existing roller straightening machines for heavy plates cannot well adjust the straightening mechanism for heavy plates of different thicknesses, thereby affecting the straightening operation of heavy plates of different thicknesses.
[0007] Therefore, there is an urgent need for a finishing straightening machine for heavy plates. Summary of the Invention
[0008] The object of the present invention is to provide a finishing straightening machine for heavy and wide plates, so as to solve the limitation problem of the existing straightening machine when adjusting the straightening mechanism for heavy and wide plates with different thicknesses.
[0009] The technical solution of the present invention is as follows:
[0010] A finishing straightening machine for heavy and wide plates, comprising: a bottom plate, and a feeding component, an adjusting component and a cleaning component installed on the top of the bottom plate; the adjusting component includes a fixing frame and a positioning plate installed on the top of the bottom plate, and a fixing plate is fixedly assembled on the inner wall of the fixing frame; a motor I is fixedly assembled on the outer wall of the positioning plate, a driving wheel is fixedly assembled at the end of the output shaft of the motor I, a toothed plate is meshed with the outer wall of the driving wheel, a clamping plate is fixedly assembled at the end of the toothed plate away from the positioning plate, the outer wall of the clamping plate is meshed with the inner wall of the fixing plate, a limiting rod is fixedly assembled on the side of the clamping plate away from the fixing plate, a straightening roller I is fixedly assembled on the outer wall of the positioning plate, and a positioning frame is fixedly assembled on the top of the bottom plate, and a straightening roller II is fixedly assembled on the outer wall of the positioning frame.
[0011] The driving wheel is driven to rotate by the motor I, so as to drive the two toothed plates to move towards each other, and then drive the clamping plate to move horizontally. While the clamping plate is moving, the limiting rod limits the clamping plate until the two clamping plates are respectively clamped and fixed with the two fixing plates. Finally, the height of the positioning plate is adjusted according to the actual thickness of the heavy and wide plate, which is beneficial to adjusting the height of the straightening roller I according to the thickness of the heavy and wide plate, adjusting the straightening roller I to a suitable position, so that the distance between the straightening roller I and the straightening roller II can be adapted to the thickness of the heavy and wide plate.
[0012] Preferably, the feeding component includes a feeding table installed on the top of the bottom plate, a groove is opened in the inner wall of the feeding table, a motor II is fixedly assembled on the top of the feeding table, a driving ring is fixedly assembled at the bottom end of the output shaft of the motor II, a transmission belt is meshed with the outer wall of the driving ring, a connecting block is fixedly assembled on the outer wall of the transmission belt, and a feeding roller is rotatably connected to the inner wall of the feeding table.
[0013] The heavy and wide plate is placed on the top of the feeding roller, and then the driving ring is driven to rotate by the motor II. The rotation of the driving ring drives the transmission belt to rotate, and the rotation of the transmission belt drives the connecting block to move, and finally the heavy and wide plate is pushed to the top of the straightening roller II, which is beneficial to improving the convenience of feeding the heavy and wide plate, reducing the workload of the staff, and ensuring the normal use of the device.
[0014] Preferably, the cleaning component includes a positioning pipe fixedly communicated with the top of the fixing frame, and a blower is fixedly assembled on the inner wall of the positioning pipe. When straightening the heavy and wide plate, oxide skin debris may be generated. The blower provided blows the broken oxide skin debris away to prevent these debris from wearing the outer wall of the heavy and wide plate.
[0015] Preferably, both ends of the straightening roll I are fixedly equipped with retaining plates. By setting the retaining plates, it is beneficial to limit the position of the wide and thick plate and prevent the problem of the wide and thick plate falling off.
[0016] Preferably, a lifting ring is fixedly assembled on the top of the fixing frame. The number of the lifting rings is four groups, and the four groups of lifting rings are evenly distributed at the four corners of the top of the fixing frame. Through the lifting rings, the position of the device can be changed, which is beneficial to improve the convenience of the device during movement.
[0017] Preferably, the number of the toothed plates, the limiting rods and the clamping plates is two groups, and the two groups of toothed plates, limiting rods and clamping plates are symmetrically distributed on both sides of the driving wheel. By limiting the number and position of the toothed plates, the limiting rods and the clamping plates, it is beneficial to improve the fixing effect on the positioning plate, and further ensure the normal straightening operation of the wide and thick plate.
[0018] Preferably, a sliding groove is opened at one end of the toothed plate away from the clamping plate, and the inner wall of the sliding groove is slidably connected with the adjacent side limiting rod. By setting the sliding groove, it is beneficial that during the movement of the toothed plate, the adjacent side limiting rod can be slidably connected with the toothed plate, and further does not affect the normal movement of the toothed plate.
[0019] The beneficial effect of the present invention is that: compared with the prior art, the wide and thick plate finishing straightening machine drives the driving wheel to rotate through the motor I, thereby driving the two groups of toothed plates to move in opposite directions, and further driving the clamping plate to move horizontally. While the clamping plate is moving, the limiting rod limits the clamping plate until the two clamping plates are respectively clamped and fixed with the two fixing plates. Finally, the height of the positioning plate is adjusted according to the actual thickness of the wide and thick plate, which is beneficial to adjust the height of the straightening roll I according to the thickness of the wide and thick plate, adjust the straightening roll I to a suitable position, so that the distance between the straightening roll I and the straightening roll II can be adapted to the thickness of the wide and thick plate, and further improve the application range of the device. It solves the limitation problem of the existing straightening machine when adjusting the straightening mechanism for wide and thick plates with different thicknesses.

By limiting the number and position of the toothed plate 306, the limiting rod 308 and the clamping plate 307, it is beneficial to improve the fixing effect of the positioning plate 302, and thus ensure the normal straightening operation of the heavy plate.
[0030] As shown in Figure 1 , Figure 2and Figure 4 As shown in Figure 4 , the feeding assembly 2 includes a feeding table 201 installed on the top of the bottom plate 1. A groove 202 is formed in the inner wall of the feeding table 201. A motor II 203 is fixedly assembled on the top of the feeding table 201.
