Description

Technical Field

[0002] The rolling mill is the main equipment for steel rolling production. In the bar and wire rod product production line, short-stress horizontal and vertical rolling mills are arranged alternately. The rolling mill is provided with an upper roll axial adjustment rod. By adjusting the upper roll axial adjustment rod, the symmetry of the pass profiles of the upper and lower rolls can be achieved, and the symmetry of the rolled piece profile after rolling can be satisfied. However, the stress situation of the rolling mill is relatively complex. The vertical rolling mill often produces axial misalignment of the rolls due to factors such as the self-weight of the rolls, assembly, and the incoming material profile, resulting in deviation of the symmetry of the rolled piece profile after rolling and unstable continuous rolling state. During rolling production, it is necessary to manually use a wrench to adjust the axial adjustment rod to achieve pass symmetry. The position of the upper roll axial adjustment rod of the vertical rolling mill has a small height difference from the ground level of the on-site operation, the adjustment operation space is limited, the resistance to misalignment adjustment is large, manual adjustment is time-consuming and laborious, and the downtime is long, affecting the effective operation. Summary of the Invention

[0003] The purpose of the utility model is to provide an adjusting device for misaligned rolls of a short-stress vertical rolling mill capable of on-line adjustment. A power source is provided by a three-phase asynchronous motor through a reducer, and the connecting rod can be driven to quickly adjust the misaligned rolls. By switching the phase-changing switch of the motor, the switching of quick upward or downward adjustment of the misaligned rolls can be satisfied, thereby overcoming the problems of large resistance to misalignment adjustment and limited operation space. Electric power replaces manual operation, saving time and effort, greatly reducing the misalignment adjustment time, improving the effective operation rate of production, and solving the problems existing in the background technique.

[0004] The technical solution of the utility model is: an adjusting device for misaligned rolls of a short-stress vertical rolling mill capable of on-line adjustment, comprising a phase-changing switch, a three-phase asynchronous motor, a reducer, a flanged universal joint, a connecting rod, a connecting rod support plate, an internal hexagonal socket head, a bottom plate, a wire collecting disc, fixed casters, universal wheels, and a trolley pushing handrail. The bottom plate is a rectangular steel plate. A connecting rod support plate is welded at the center position on the upper side of one short side, and a fixed caster is installed at each of the two lower corners. A trolley pushing handrail is welded on the upper side of the other short side. The phase-changing switch is fixed on the trolley pushing handrail, and a universal wheel is installed at each of the two lower corners.

The three-phase asynchronous motor, the reducer, the flanged universal joint, the connecting rod, and the connecting rod support plate are arranged in sequence on the center line in the long side direction of the bottom plate, and the wire collecting disc is fixed beside the three-phase asynchronous motor.

[0005] The three-phase asynchronous motor and the reducer are fixedly fastened by bolts to form an integrated speed-reducing motor, and the reducer is fastened to the bottom plate by bolts.

[0006] For the flange type universal joint, the flange side is connected to the speed reducer through a flange coupling, and the connection method is in the form of a keyway and a flat key. The other side is welded to the connecting rod.

[0007] The connecting rod is a steel bar, one end of which is welded to the flange type universal joint, and the other end is welded to the hexagon socket head.

[0008] The connecting rod support plate is a small rectangular steel plate with a through U-shaped groove in the middle of one short side. The other short side is welded to the bottom plate, and the center line of the semi-circle of the U-shaped groove is coaxial with the connecting rod.

[0009] The beneficial effects of the present utility model are as follows: A power source is provided by a three-phase asynchronous motor through a speed reducer to drive the connecting rod, enabling quick adjustment of the misaligned rollers. By switching the phase change switch of the motor, it can meet the quick switching of the upward or downward adjustment of the misaligned rollers, thus overcoming the problems of large resistance in misaligned roller adjustment and limited working space. Electric operation replaces manual operation, saving time and effort, greatly reducing the misaligned roller adjustment time, and improving the effective operation rate of production.
