Automatic adjustment device for the pinch roller shaft before the high-speed double-length flying shear

Abstract

The invention discloses an automatic adjustment device for the roller shaft of the pinch roller in front of the high-speed double-foot flying shear, which includes a roller table body, an embedded roller table and a rolling body. Two rows and two columns are symmetrically provided with square positioning grooves A and square positioning grooves B; both sides of the embedded roller table are symmetrically casted with square bar-shaped positioning rods A and bar-shaped positioning rods B, and the embedded roller table is socketed In the rolling groove, the square bar-shaped positioning rod A is embedded in the square positioning groove A. The automatic adjustment device of the pinch roller shaft before the high-speed double-scale flying shear changes sliding into rolling mode, the adjustment process is smoother, the probability of jamming is reduced, the equipment adjustment efficiency and the safety of the adjustment process are improved, and the electric The combination of magnetism and force effectively reduces the impact and vibration of the equipment, optimizes the adjustment process, and realizes automatic adjustment.

Description

technical field [0001] The invention relates to the technical field of steel rolling equipment, in particular to an automatic adjustment device for the roller shaft of a pinch roller before high-speed double-length flying shear. Background technique [0002] The position of the flying shear is a place where the design of the guide groove of the rolling element is relatively difficult. Every manufacturer adopts a sliding design. When the sliding design is used, the friction of the roller table is large during motion, and the loss is also large, which will reduce the accuracy of motion and use. life, and the existing roller table, in the process of movement, is not easy to stop due to the inertia of its own movement, and usually stops due to the resistance of the collision. At this time, the impact force generated by the collision will cause damage to the roller table or the roller shaft. Large damage will greatly reduce the service life. Using manual adjustment to adjust the ...
