Description

Technical Field

[0001] The utility model relates to the technical field of drawing and leveling machines, and more specifically, to a cold-rolled strip flat drawing and leveling machine. Background Art

[0002] Cold-rolled strip steel is a strip-shaped metal material produced by the cold rolling process, which is usually used to manufacture automotive parts, household appliances, building materials, etc. The flattening and leveling machine is a device used for metal material processing, which is usually used to stretch and flatten metal plates or strips to eliminate stress in the material and improve the surface flatness.

[0003] After searching, a Chinese patent with publication number CN218361427U discloses a straightening machine. The existing equipment driving device mainly relies on the motor to drive the lifting and lowering. Sometimes the two ends are not synchronized when driving up or down, resulting in uneven force, and the motor is easily damaged. When the motor fails, it is difficult to replace and cannot be adjusted manually in time, resulting in reduced material production efficiency. Through manual drive, the upper and lower groups of bending rollers are simultaneously moved up and down close or away, and the height balance on both sides is better and more accurately adjusted, so that the steel plate is more evenly stressed. The driving mode of the driving device is a simple manual driving mode. If the driving device is damaged, it is easy to replace, avoiding the problem of being unable to use in the absence of electricity or being unable to be manually adjusted in time after the components are damaged, resulting in work stopping and reducing production efficiency.

[0004] When the tension leveler is leveling the cold-rolled strip, its leveling rollers are easily subject to friction and wear due to long-term high-speed rotation and contact with the strip, resulting in local overheating, which easily affects the flatness and surface quality of the steel plate.

[0013] Preferably, support frames are fixedly connected to both sides of the bottom of the working plate of the tensioning and straightening machine.

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting a leveling and cooling mechanism, the fan drives the air to circulate, so that the air inside the ventilation pipe circulates, and then takes away the heat on the leveling roller, achieving a good cooling effect. At the same time, during the rotation of the leveling roller, the oil-absorbing cotton is always pressed against one of the leveling rollers by the rebound force of the spring, so that the lubricating oil is squeezed onto the leveling roller through the oil-absorbing cotton, thereby reducing the friction between the leveling roller and the cold-rolled strip, thereby reducing the possibility of local overheating. Compared with the prior art, the heat of the leveling roller can be taken away by the air circulation inside the ventilation pipe, avoiding overheating between the leveling roller and the strip, and at the same time, the leveling roller can continuously contact the lubricating oil, reducing the friction between the leveling roller and the strip, avoiding high temperature from the source, thereby avoiding affecting the leveling effect of the strip and the quality of the finished product;

[0016] 2. The second motor drives the threaded rod to rotate, so that the two threaded sleeves move closer to or away from each other, thereby driving the two moving sleeves and the rollers to move closer to or away from each other through the moving rod. The strip moves on the roller to play a limiting role. At the same time, it can be adjusted according to the width of the strip, and is suitable for limiting strips of different widths to avoid strip misalignment affecting the flatness effect.

[0026] The leveling and cooling mechanism includes a fixed frame 6, which is fixed on the top of the working plate 1 of the straightening machine. A ventilation pipe 7 is fixedly connected inside the fixed frame 6, and a leveling roller 8 is rotatably connected to the outside of the ventilation pipe 7.

[0027] As attached Figure 1-4 As shown, both ends of the ventilation pipe 7 pass through the fixed frame 6 and extend to the outside of the fixed frame 6, the top of the spring 12 is fixedly connected to the top of the inner wall of the fixed frame 6, and the bottom of the spring 12 is fixedly connected to the top of the oil storage tank 11, so that the oil-absorbing cotton 23 is always pressed against the smoothing roller 8 through the rebound force of the spring 12 to prevent the lubricating oil from being smeared on the smoothing roller 8.

[0028] As attached Figure 1 , 2 As shown in , 3, 4, and 6, the top of the oil-absorbing cotton 23 passes through the oil storage tank 11 and extends to the inside of the oil storage tank 11, and the bottom of the lifting slide rod 10 passes through the fixed frame 6 and extends to the bottom of the fixed frame 6, which facilitates the up and down movement of the lifting slide rod 10.

During long-term high-speed rotation of the leveling roller 8 and contact with the strip, the rollers and guide rollers are susceptible to friction and wear, resulting in local overheating. During use, the fan 9 is started to drive air circulation, thereby allowing air to circulate inside the ventilation pipe 7, thereby taking away the heat on the leveling roller 8, achieving a good cooling effect. At the same time, during the rotation of the leveling roller 8, the rebound force of the spring 12 makes the oil-absorbing cotton 23 always press against one of the leveling rollers 8, so that the lubricating oil inside the oil storage tank 11 is squeezed onto the leveling roller 8 through the oil-absorbing cotton 23, thereby reducing the friction between the leveling roller 8 and the cold-rolled strip, thereby reducing the possibility of local overheating, thereby preventing the quality of the strip from being affected by temperature.
