Description

Technical Field

[0001] The invention relates to the field of steel plate correction, in particular to a device for adding a hard-state straightening unit to a degreasing unit. Background Art

[0002] In the steel cold rolling industry, the rolling mill is rolled according to different production processes during the production process. AGC control and bending roll control are important control methods in the steel plate rolling process. In the process of AGC control and bending roll control adjustment, it is inevitable that the steel plate will have quality defects such as single-sided waves and double-sided waves, which also brings disadvantages to the high-speed production of the subsequent process. The strip is prone to deviation and strip breakage. In order to improve the poor plate shape ability and eliminate the C warping and L warping of the steel plate, the plate shape correction and surface inspection of strips of different hardness are usually achieved through a tension and bending straightening machine. The existing degreasing unit adds a hard-state tension and straightening unit, which is composed of an inlet tension roller group, a hard-state tension and straightening machine, and an outlet tension roller group. The hard-state tension and straightening machine includes a lower bending roller box, a lower straightening roller box, an upper straightening roller box, and an upper and lower lifting device. Under a certain tension, that is, elongation, the hard-state tension and straightening machine eliminates the strip shape defects such as wave shape, scoop bend, sickle bend, etc., improves the plate shape quality, improves the plate passing capacity of the unit, and reduces the defects caused by plate shape defects. Degraded products, avoid sticking steel and slipping after annealing, but in actual use, in order to prevent the steel plate surface from adhering to the working rolls in the lower bending roller box, the lower straightening roller box and the upper straightening roller box, a driving force (motor) is usually used to drive the working rolls to rotate at a suitable speed. The working rolls have a certain number, and the existing device uses a certain number of driving forces (motors) for driving. However, the number of installed driving forces (motors) is large, and daily maintenance of the driving force (motor) is time-consuming and labor-intensive, and the height of the lower bending roller box, the lower straightening roller box and the upper straightening roller box needs to be adjusted at any time according to the usage. While adjusting the height of the lower bending roller box, the lower straightening roller box and the upper straightening roller box, the height of the driving force (motor) must also be adjusted. The driving force (motor) needs to be connected to the power cord when in use. The adjustment of the height of the driving force (motor) will also drive the power cord to move, and too many power cords will inevitably pose a safety hazard.

The working rollers 502 rotate and, under the transmission action of the two sets of sprocket wheels 507 and the two chains 508, drive a set of intermediate rollers 503 to rotate. Then, under the action of the three sets of gears 504, the three sets of intermediate rollers 503 all rotate, thereby causing the working rollers 502 and intermediate rollers 503 in the upper bending roller box 5 to rotate. Since the structure of the upper bending roller box 5 is the same as that of the lower bending roller box 6, the lower straightening roller box 7, and the upper straightening roller box 8, the working rollers and intermediate rollers in the lower bending roller box 6, the lower straightening roller box 7, and the upper straightening roller box 8 all rotate, thereby avoiding the phenomenon of steel sticking.

[0039] During use, the rotation of the driving rod 1003 will drive the fan blades 1005, and the rotation of the fan blades 1005 will accelerate the flow of air in the pipe 1001. Both ends of the pipe 1001 are open. The air in the pipe 1001 will blow from the position close to the fan blades 1005 to the motor 1002, which can accelerate the flow of air around the motor 1002. In addition, since the aperture of the pipe 1001 gradually decreases from one end close to the fan blades 1005 to the other end, the air in the pipe 1001 is When flowing inside, the temperature of the air will gradually decrease, and the air with lower temperature will blow toward the motor 1002, which can speed up the heat dissipation of the motor 1002; since the fan blades 1005, the motor 1002, the driving rod 1003, the bevel gear three 1007 and the bevel gear two 1006 are all inside the pipe 1001, the interference of the outside world to the fan blades 1005, the motor 1002, the driving rod 1003, the bevel gear three 1007 and the bevel gear two 1006 can be reduced through the pipe 1001.

[0040] It should be noted that an external power supply and controller are required when the device is in use. The external power supply provides power for the cylinder 301, the reduction motor 407, the motor 1002 and the cylinder 1104, and the operation of the cylinder 301, the reduction motor 407, the motor 1002 and the cylinder 1104 is controlled by the external controller; it should be noted that the reduction motor 407 needs to adopt a reduction motor with its own structure; it should be noted that the motor 1002 needs to adopt a motor with suitable driving force.

[0041] It should be noted that the working rolls and intermediate rolls in the upper bending roll box 5, the lower bending roll box 6, the lower straightening roll box 7 and the upper straightening roll box 8 are all hardened by GCr15 medium frequency, and the surface hardening hardness is HRC62-64; the depth is 2-3mm.
