Description

technical field [0001] The invention relates to the technical field of rolling wheel transportation, in particular to an automatic rolling wheel transportation production line and a control method. Background technique [0002] After the wheel rolling is completed, the wheel needs to be slowly cooled, and then tempered and quenched. From the completion of the wheel rolling to the slow cooling process, it needs to be transported by the conveyor roller. The conveyor roller is driven by the motor to drive the reducer to rotate and decelerate The rotation of the machine drives the roller table to rotate through the chain, thereby driving the wheels on the roller table to move. [0003] In the process of transporting the wheels, there are the following problems: First, the problem of wheel deviation: due to the roughness and wear of the two rollers at both ends of each roller table, the friction between the two rollers and the wheels is different, resulting in The wheels tend to...

Problems solved by technology

[0003] In the process of transporting the wheels, there are the following problems: First, the problem of wheel deviation: due to the roughness and wear of the two rollers at both ends of each roller table, the friction between the two rollers and the wheels is different, resulting in The wheels tend to shift during transportation, which causes one end of the wheel to fall off the roller, and the roller shaft between the two rollers is easily squeezed and deformed, resulting in failure to rotate normally. The roller shaft must be replaced, resulting in a certain Economic loss, and seriously affect on-site production efficiency

Second, there is the problem that low-temperature steel needs to be manually screened during transportation: low-temperature steel may appear in the process of heating, rolling and transporting the wheel. If the temperature of the wheel is lower than a certain temperature, it will affect it during the later slow cooling process. The release of internal stress affects the mechanical properties of the wheel and does not meet the process requirements of slow cooling. The traditional operation method is to manually measure and observe the temperature of the wheel during transportation. When the temperature of the wheel is lower than a certain temperature, sometimes it is necessary to stop the machine Afterwards, the wheels are screened out for slow cooling, tempering, and quenching processes, and finally the relevant performance indicators are tested. Manual screening of wheels that do not meet the process requirements is not only labor-intensive, but also has poor screening accuracy and low efficiency, which affects normal operation. production rhythm
