Description
Technical Field
The invention relates to a double-station horizontal-vertical conversion rolling mill.
Background
At present, the horizontal-vertical conversion rolling mill mainly has the following two structural forms:
the horizontal-vertical conversion rolling mill with a rotating frame is mainly composed of a motor, a clutch, a bevel gear box, a combined gear box, a rotating frame, a rotating base and the like. When the clutch is used as a flat rolling mill, the clutch at the motor end is directly connected with the input shaft of the combined gear box; when the clutch is used as a vertical rolling mill, the clutch is connected with the long shaft of the bevel gear box, and horizontal transmission is converted into vertical transmission through the bevel gear box. The WGT-shaped drum-shaped gear coupling shaft between the combined box and the bevel gear box drives the combined box to rotate.
A fixed horizontal-vertical conversion rolling mill is shown in figure 4, conversion between a horizontal rolling mill and a vertical rolling mill is achieved through a gear shifting speed reducer, the specific structure is shown in figure 4, and the fixed horizontal-vertical conversion rolling mill mainly comprises a motor, a horizontal roller composite speed reducer, a vertical roller composite speed reducer and a bevel gear box. The flat roller composite speed reducer is provided with an input shaft and three output shafts, and an H gear and a V gear are designed inside the flat roller composite speed reducer. When the clutch is in an H gear position, torque is transmitted downwards, and two output shafts at the lower end are used as transmission shafts of the flat rolling mill; when the clutch is in a V gear, the torque is transmitted upwards, and the torque is transmitted to the vertical rolling composite speed reducer through the bevel gear box.
However, the existing horizontal-vertical conversion rolling mills with two structural forms have the following problems:
(1) the gear shifting sliding block of the combined gear box or the flat roll composite speed reducer is fast in abrasion, easily generates out-of-gear faults and has great influence on production;
(2) the service life of a tooth clutch between a motor and a gear box is short, and because the rotating frame of the rotating frame type horizontal-vertical conversion rolling mill needs to be rotationally switched between a horizontal state and a vertical state, the motor is connected with the gear box through the tooth clutch, and the rotating frame is positioned only by a locking cylinder, so that the positioning precision of the frame is low, the coaxiality between the inner teeth and the outer teeth of the tooth clutch is poor, and the tooth surface is quickly abraded;
(3) because the bevel gear box is positioned under the rolling mill base, cooling water of the rolling mill can easily enter the box body at the peephole position of the bevel gear box and the half-tooth coupling position of the connecting shaft, and enters the oil tank along with lubricating oil, so that water enters a lubricating station, and the service life of a mechanical transmission system is influenced;
(4) the rotating frame rotates in the track through the guide wheel, so that the rolling mill can be switched between a horizontal mode and a vertical mode. A gap of 5mm is designed between the guide wheel and the track, the rim of the guide wheel is clamped between guide rail positioning blocks (the designed gap is 0.05-0.28 mm) after the rotating frame is in place, the gap is gradually increased along with the operation of the frame, and the rim of the guide wheel is in point contact with the positioning blocks, so that the positioning effect cannot be really played, the positioning precision of the rotating frame is reduced, and the mounting precision of equipment cannot be ensured;
(5) the bolts of the reamed holes at the two ends of the WGT-shaped drum-tooth connecting shaft between the combined gear box and the bevel gear box are easy to break, and the bolts are difficult to process after being broken because the shaft is arranged in the rotating frame and the rolling mill housing, so that the shutdown time is long;
(6) the drum-shaped tooth connecting shaft of the flat rolling mill of the fixed flat-vertical conversion rolling mill needs to penetrate through a housing of the vertical rolling mill, so that the length of the connecting shaft is longer, the length of the general drum-shaped tooth connecting shaft exceeds three meters, the swinging amount of the shaft during rotation is large, the shaft is difficult to hoist, and a special connecting shaft replacement bracket needs to be designed;
(7) the clutch gear of the flat-roll composite speed reducer is easy to damage due to the action of axial force.
