When the mounting and positioning block 51 is used for mounting the upper roller system 4, the mounting and positioning block is positioned with the lower roller system 5 to ensure that the mounting is accurate and in place, and after the mounting is finished, the mounting and positioning block 51 is detached.
In order to ensure the safety of the plate flattening process and avoid the damage of equipment caused by overload, the invention designs a hydraulic safety protection device in a pertinence way, and the hydraulic cushion 19 is an oil cylinder with the stroke of about 20mm and only supplies oil to the plug cavity. The hydraulic cushion 19 and the balance oil cylinder 24 cooperate to realize the equipment safety protection in the plate leveling process, and the protection process is as follows: 1. the pressure sensor is arranged to measure the pressure in the cavity of the hydraulic cushion 19 and feed back the measurement result to the numerical control system; 2. according to the designed maximum bearing capacity of the leveler, the pressure in the cavity of the hydraulic cushion 19 under the maximum bearing capacity is calculated, the pressure is set in a numerical control system to serve as the maximum safe use pressure, and the maximum safe use pressure is compared with the actual measurement pressure of the pressure sensor in real time; 3. the numerical control system sets a protection program, and when the detection feedback pressure in the plug cavity of the hydraulic cushion 19 is greater than the maximum safe use pressure set by the system, the system automatically executes the protection program: the cavity of the hydraulic cushion 19 is decompressed, the balance oil cylinder 24 is lifted to drive the floating beam 6 and the upper roll system 4 to lift the height, and the plate flattening process is ended; 4. when a user uses a leveler to level a plate exceeding the maximum processing capacity of the equipment in an illegal way, the pressure detected in the plug cavity of the hydraulic cushion 19 exceeds the set value of the system, the protection program is automatically executed, the upper roller system 4 is lifted, the leveling force in the equipment is reduced, and the equipment damage caused by overload use is avoided.
As shown in fig. 9, the roll gap angle adjustment is realized by adjusting the size of the angle a. As shown in fig. 10, the roll gap shape adjustment is realized by adjusting the vertical distance h between the upper and lower work rolls. As shown in fig. 11 and 12, the roll crown adjustment is achieved by changing the deflection of the work rolls, fig. 11 is a medium concave form, and fig. 12 is a convex-concave mixed form.
