Description

Technical Field

[0001] This utility model relates to the field of auxiliary feeding structures, specifically a flatness shaping device for hot-rolled coil processing. Background Technology

[0002] During the production of hot-rolled coils, defects such as edge waviness, center waviness, and warping can easily occur in the sheet due to factors such as rolling process, uneven cooling, or residual stress, affecting the quality of subsequent processing and yield. Traditional straightening equipment typically uses an integral straightening roller structure, which flattens the sheet by fixing the roller gap or simply pressing it down with hydraulic pressure.

[0003] Chinese Patent Publication No. CN221935045U discloses a steel plate flatness shaping device, including an operating table. The operating table has an internal mounting groove. A reduction oil pump is mounted on the front side of the lower surface of the mounting groove. A threaded rod is fixedly connected to the output shaft end of the reduction oil pump. The end of the threaded rod away from the reduction oil pump is connected to the rear sidewall of the mounting groove via a bearing. This invention uses an electric cylinder to extend and retract, causing the extrusion roller to press against the upper surface of the steel plate. Starting the reduction oil pump drives the threaded rod to rotate clockwise or counterclockwise. The nut threaded to the threaded rod drives a moving plate and the electric cylinder to move forward and backward, causing a fixed block to drive the extrusion shaft and extrusion roller to roll back and forth on the upper surface of the steel plate, making the steel plate flat. This ensures that the steel plate meets usage requirements after shaping. When used with other components, the contact between planes is more seamless, enhancing its practicality.

[0004] The flatness shaping device of the above patent has an integral straightening roller that cannot make precise adjustments for local deformations such as unilateral waves or central bulges. This may result in residual stress or secondary deformation after straightening. The uniformly applied straightening pressure may cause over-straightening of material thinning or under-straightening defects in some areas, affecting the thickness uniformity of the board. Utility Model Content

[0005] The purpose of this invention is to provide a flatness shaping device for hot-rolled coil processing. A first hydraulic cylinder with a pressure sensor is mounted on a base. A telescopic rod surrounds the pressure sensor, and a base plate is mounted on the movable end of the telescopic rod. Support columns surround the base, and a fixed base is mounted on the end of each support column furthest from the base. A second hydraulic cylinder is mounted at the lower end of the fixed base, and a connecting rod is mounted on the movable end of the second hydraulic cylinder. A straightening roller is mounted on one end of the connecting rod. When material is placed on the base plate, the second hydraulic cylinder drives the straightening roller downwards. A worker or a pusher device placed at one end of the material propels the material forward. If the material surface has waves, the pressure on the base plate below the wave area is different. The pressure sensor controls the movable end of the first hydraulic cylinder to extend, making its pressure equal to the pressure on the other base plates. As the material moves forward, the straightening roller rolls and straightens the material. This segmented straightening method solves the problem of insufficient straightening force in traditional devices and addresses the issues mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flatness shaping device for hot-rolled coil processing, comprising a first hydraulic cylinder, a pressure sensor being provided on the movable end of the first hydraulic cylinder, and a telescopic rod being provided around the pressure sensor. A base plate is provided on the movable end of the telescopic rod, a connecting block is provided at the lower end of the first hydraulic cylinder, a ground contact base is provided at the lower end of the connecting block, a support column is provided at the upper end of the ground contact base, and a fixed base is provided at the end of the support column away from the ground contact base.

[0007] Preferably, a second hydraulic cylinder is provided at the lower end of the fixed base, and the fixed end of the second hydraulic cylinder is bolted to the fixed base.

[0008] Preferably, a connecting rod is provided on the movable end of the second hydraulic cylinder, and the connecting rod is bolted to the second hydraulic cylinder.

[0009] Preferably, a straightening roller is provided on the end of the connecting rod away from the second hydraulic cylinder, and the straightening roller is connected to the rotating bearing of the connecting rod.

[0010] Preferably, the connecting block is equipped with an oil pump.

[0011] Preferably, the oil pump is provided with an oil delivery pipe, and the oil delivery pipe is connected to the first hydraulic cylinder at the other end away from the oil pump.

[0012] Preferably, a throttle valve is provided on the oil pipeline.

[0013] Preferably, the telescopic rod is provided with a stabilizing rod, which is connected to the movable end of the telescopic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention comprises a first hydraulic cylinder mounted on a ground contact base, a pressure sensor mounted on the first hydraulic cylinder, and a telescopic rod surrounding the pressure sensor. A base plate is mounted on the movable end of the telescopic rod. Support columns surround the ground contact base, and a fixed base is mounted on the end of each support column furthest from the ground contact base. A second hydraulic cylinder is mounted at the lower end of the fixed base, and a connecting rod is mounted on the movable end of the second hydraulic cylinder. A straightening roller is mounted on one end of the connecting rod. When material is placed on the base plate, the second hydraulic cylinder drives the straightening roller to press down. A worker or a pusher device placed at one end of the material propels the material forward. If the material surface has waves, then there is a wave position... Since the pressure on the bottom plate is different, the pressure sensor controls the extension of the movable end of the first hydraulic cylinder to make its pressure the same as that of the other bottom plates. As the material moves forward, the straightening roller rolls the material to straighten it. This segmented straightening solves the problem of insufficient straightening force in traditional devices. It effectively avoids the problem that existing flatness shaping devices cannot accurately adjust for local deformations such as unilateral waves or central bulges by using integral straightening rollers. This can lead to residual stress or secondary deformation after straightening. The uniformly applied straightening pressure may cause over-straightening and material thinning or under-straightening defects in some areas, affecting the thickness uniformity of the plate.

As the material moves forward, the straightening roller 15 rolls and straightens the material. This segmented straightening solves the problem of insufficient straightening force in traditional devices.
