Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stainless steel sheet processing technology, and specifically relates to a stainless steel sheet rolling device to prevent centering deviation. Background Technology
[0002] In the rolling process of stainless steel sheet, centering deviation is one of the main problems affecting product quality and production efficiency. When traditional rolling equipment is used for high-speed production, the strip steel is prone to not being accurately aligned with the center position of the rolling equipment, resulting in deviations in various aspects such as size, shape, performance, and thickness of the rolled sheet. This deviation not only affects the quality and appearance of the product, but also reduces production efficiency and increases production costs.
[0003] A search revealed an anti-deviation steel strip rolling device with prior art authorization announcement number CN222343788U. This device uses a pushing component between the upper and lower pressure rollers to push guide rollers to center and prevent deviation of the rolled steel strip. However, the distance between the upper and lower pressure rollers is limited by the height of the guide rollers, making it unsuitable for steel strips of different thicknesses. Another search revealed a steel plate roughing mill with prior art authorization announcement number CN222153390U. This mill uses a limiting block in the feed trough to limit the steel plate and prevent it from shifting due to force during roughing. However, this device clamps and limits the steel plate using the limiting block, which causes friction and cannot guarantee normal forward transport of the steel plate. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stainless steel sheet rolling device that prevents centering deviation. The blowing mechanism can blow away dust and impurities on the surface of the stainless steel sheet to be rolled, preventing residual impurities on the stainless steel sheet from entering the rolling mill and causing rolling defects. The centering clamping mechanism clamps the stainless steel sheet to prevent centering deviation during the rolling process.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A stainless steel sheet rolling device for preventing centering deviation includes a purging mechanism, a centering clamping mechanism, a rolling mill, a support platform, conveying rollers, and a slag-blocking plate. The purging mechanism is located at the front end of the support platform, the centering clamping mechanism is located in the middle of the support platform, multiple sets of conveying rollers are located in the middle of the support platform, and a slag-blocking plate is located at the lower part of the conveying rollers and is fixed in the middle of the support platform. The rolling mill is located at the rear end of the support platform. The stainless steel sheet to be rolled is conveyed forward by the conveying rollers. The purging mechanism purifies the stainless steel sheet to prevent residual impurities on the stainless steel sheet from entering the rolling mill and causing rolling defects. The slag-blocking plate at the lower part of the conveying rollers prevents impurities on the stainless steel sheet from falling onto the centering clamping mechanism and causing the mechanism to jam. During the conveying process, the centering clamping mechanism centers and clamps the stainless steel sheet to prevent centering deviation. The rolling mill then completes the rolling of the stainless steel sheet.
[0007] The purging mechanism includes an air pump, a main air pipe, branch air pipes, high-pressure nozzles, a swing mechanism, a dirt-proof plate, and a maintenance plate. The air pump is located outside the support platform and is connected to the main air pipe. The main air pipe is rotatably connected to multiple sets of branch air pipes via a rotating connector. The multiple sets of branch air pipes are symmetrically distributed vertically and are located in the middle of the support platform. Each branch air pipe is equipped with multiple sets of high-pressure nozzles, which are evenly spaced. The other end of each branch air pipe is equipped with a swing mechanism. A dirt-proof plate is located between the swing mechanism and the branch air pipe, and is rotatably connected to the branch air pipe. The dirt-proof plate is also fixedly connected to the support platform. A maintenance plate is located outside the swing mechanism and is also located on the support platform. The air pump supplies air to the main air pipe and branch air pipes. The high-pressure nozzles on the branch air pipes blow away impurities on the stainless steel sheet. The swing mechanism controls the rotation and swing of the branch air pipes, expanding the purging range, improving purging efficiency, avoiding dead zones, and preventing residual impurities on the stainless steel sheet from entering the rolling mill and causing rolling defects.
[0008] The swing mechanism includes a motor, a drive shaft I, a sprocket I, a chain, a sprocket II, a drive shaft II, and a limiting slide groove. The motor is mounted on the outside of the inspection plate, and its output end is connected to the drive shaft I. A gear I is mounted on the drive shaft I and is fixed to a branch air pipe. Gear I meshes with rack I, and rack I meshes with multiple sets of gears II. Gears II are fixed to the branch air pipe. Rack I is also positioned in the limiting slide groove, which is slidably connected to the limiting slide groove. The limiting slide groove is fixed to a support platform. A sprocket I is also mounted on the drive shaft I and is connected to sprocket II via a chain. Sprocket II is mounted on the drive shaft II, and a gear III is mounted on the drive shaft II and fixed to the branch air pipe. Gear III meshes with gears... Rack II meshes with multiple sets of gears IV, which are fixed on the branch air pipes. Rack II is also positioned within the limiting groove. The motor controls the rotation of drive shaft I, which in turn drives sprocket I and gear I to rotate. Gear I meshes with rack I, which in turn meshes with gear II. Gears I and II drive the upper branch air pipes to rotate. Sprocket I drives sprocket II via a chain, which in turn drives drive shaft II to rotate. Drive shaft II drives gear III to rotate, which meshes with rack II. Rack II meshes with gear IV, which in turn drives the lower branch air pipes to rotate. The rotation of multiple sets of branch air pipes at both the top and bottom purifies the stainless steel sheet to be rolled, resulting in a larger purging area and improved purging efficiency.
[0009] The centering clamping mechanism includes a support column, a limiting ring, a positioning ring, a connecting shaft, a vertical side guide roller, and an electric actuator. Two sets of support columns are installed inside the support platform, and the support columns are also located below the slag-blocking plate. The positioning rings are slidably connected to the support columns, and the two sets of positioning rings are connected by a connecting shaft. An electric actuator is located at the lower middle part of the connecting shaft. A limiting ring is fixed on the support column to ensure the movement range of the positioning ring. The positioning ring is connected to connecting rod I by a pin. Connecting rod I, L-shaped connecting rod, connecting rod III, and connecting rod IV are sequentially connected by pins. The L-shaped connecting rod passes through clearance holes on both sides of the support platform and connects to connecting rod III. The L-shaped connecting rod is connected to a positioning seat in the middle by a pin. The seat is fixed on the outside of the support platform. Connecting rod IV is set in the guide hole on the positioning platform. The top end of connecting rod IV is connected to the vertical side guide roller, which is in contact with the conveying roller. The electric push rod controls the rise and fall of the two sets of positioning rings through the connecting shaft. The positioning ring drives connecting rod I to press down or lift up. During the pressing down or lifting up process, connecting rod I causes the L-shaped connecting rod to rotate around the positioning seat as the fulcrum. During the rotation of the L-shaped connecting rod, the other end drives connecting rod III, which drives connecting rod IV. Connecting rod IV slides in the guide hole on the positioning platform, thereby controlling the opening and closing of the vertical side guide rollers on both sides. The vertical side guide rollers center and clamp the stainless steel sheet on the conveying roller to prevent the stainless steel sheet from having centering deviation during the rolling process.
[0010] The advantages of this utility model compared with the prior art are as follows:
[0011] The purging mechanism uses high-pressure nozzles on branch air pipes to purge impurities from the stainless steel sheet. The oscillating mechanism then controls the branch air pipes to rotate and oscillate, expanding the purging range, improving purging efficiency, avoiding dead zones, and preventing residual impurities from the stainless steel sheet from entering the rolling mill and causing rolling defects. The clamping mechanism controls the vertical guide rollers on both sides to close and center. The vertical guide rollers clamp the stainless steel sheet on the conveying rollers, ensuring that the clamping does not affect the forward conveying of the stainless steel sheet and preventing centering deviations during the rolling process.
