Description

Technical Field

[0001] The utility model belongs to a turnover machine, and particularly relates to a turnover machine for ring-removing steel billets used in the production of consumable electrodes of electroslag remelting furnaces. Background Art

[0002] The production of consumable electrodes of electroslag remelting furnaces is complex, with high operation difficulty and relatively difficult preparation quality control. The consumable electrode of the electroslag remelting furnace is formed by welding a false electrode to a steel billet. When welding the false electrode, it is first necessary to ensure the concentricity between the false electrode and the steel billet. Before welding, the steel billet needs to be turned 180 degrees to achieve symmetric welding to reduce the welding deformation amount, so as to ensure the butt joint accuracy between the steel billet and the false electrode; in addition, before welding, it is also necessary to inspect and clean the surface of the steel billet, and during this process, the steel billet also needs to be turned 180 degrees to achieve inspection and cleaning of the four surfaces.

[0003] At present, the above-mentioned turnover operation is realized by means of a crane. The turnover operation is heavy, time-consuming, and occupies a large area. The turnover operation requires the use of a crane, which reduces the operation rate of the crane. Summary of the Invention

[0007] The turnover mechanism includes a ring removal, a through hole is opened in the center of the ring removal, and an external gear ring is circumferentially arranged on the edge of the ring removal;

The support is a semi-circular structural member and is welded to the traveling mechanism; the bearing seat is fixedly connected to the support, the pinion is connected to the bearing seat, and the pinion meshes with the external gear ring of the ring removal; the pinion is driven by a motor.

[0009] The through hole is cross-shaped or rectangular.

[0010] The external gear ring is welded to the ring removal.

[0011] 2 to 6 clamping cylinders are connected to the top and bottom of the through hole, and 2 to 8 screw rods are symmetrically connected to both sides of the through hole.

[0012] The clamping cylinder is an electric screw lift or a hydraulic cylinder.

[0029] The present utility model will be described in detail below in conjunction with the accompanying drawings of the specification, but it should be pointed out that the implementation of the present utility model is not limited to the following implementation modes

[0030] See Figures 1 to 6 , a stripping type billet turning machine, including a turning mechanism 1, a turning drive mechanism 2, a lifting and centering table 3, a side positioning mechanism 4, a traveling mechanism 24, and a steel rail 5. The turning drive mechanism 2 is connected to the traveling mechanism 24. The traveling mechanism 24 drives the turning drive mechanism 2 to move on the steel rail 5. The turning drive mechanism 2 drives the turning mechanism 1 to rotate. The side positioning mechanism 4 is arranged beside the lifting and centering table 3. The turning drive mechanism 2 is an even number and is respectively arranged on both sides of the lifting and centering table 3. The steel rail 5 is fixed on the equipment foundation; the lifting and centering table 3 and the side positioning mechanism 4 are both fixedly connected to the equipment foundation through anchor bolts. The traveling mechanism 24 is a wheeled traveling mechanism

[0031] The turning mechanism 1 includes a stripping ring 11. A through hole 13 is opened in the center of the stripping ring 11. An external gear ring 12 is circumferentially arranged on the edge of the stripping ring 11. The external gear ring 12 is welded and fixed to the stripping ring 11. The external gear ring 12 is composed of pin teeth or is an involute tooth and can mesh with the pinion 23

[0032] The size of the through hole 13 in the center of the stripping ring 11 is slightly larger than the size of the billet to be turned. The through hole 13 is cross-shaped or rectangular. 2 - 6 clamping cylinders 15 are connected to the top and bottom of the through hole 13. The clamping cylinders 15 are symmetrically arranged. The clamping cylinders 15 are electric screw elevators or hydraulic cylinders, with a stroke of 0 - 400 mm. The position where the clamping cylinders 15 contact the billet is a planar structure, applying force to the billet more evenly. 2 - 8 screw rods 14 are symmetrically connected to both sides of the through hole 13. The screw rods 14 are symmetrically arranged, and their stroke is manually adjusted

[0033] The number of the flipping drive mechanisms 2 is the same as that of the flipping mechanisms 1, both being two, and they are respectively arranged outside the lifting centering table 3. The flipping drive mechanism 2 includes a support 21, a bearing block 22, and a pinion 23. The support 21 is a semi-circular structural member, and the support 21 is welded to the traveling mechanism 24; the coil stripping ring 11 sits on the support 21, the bearing block 22 is fixedly connected to the support 21, the pinion 23 is connected to the bearing block 22, and the pinion 23 meshes with the external gear ring 12 of the coil stripping ring 11; the pinion 23 is driven by a motor. The number of the bearing blocks 22 is 2 to 5, and the spacing between adjacent bearing blocks 22 is the same.

[0034] In addition, the pin teeth of the external gear ring 12 are rotatable idler rollers. A semi-circular slideway is fixed inside the support 21, and the idler rollers sit on the slideway. The radius of the circle formed by the outermost points of these idler rollers is the same as the radius of the slideway, forming a rolling friction like that of a wheel. While supporting the coil stripping ring 1, it does not affect the rotation of the coil stripping ring 1.

[0035] There are two lifting centering tables 3, and the side positioning mechanism 4 is arranged on the side between the two lifting centering tables 3. The lifting centering table 3 includes a bolster 31 and a lift 32. The bolster 31 is a welded structural member, and the bolster 31 is fastened to the equipment foundation by anchor bolts. 2 to 4 lifts 32 are fixedly connected to the bolster 31. The lift 32 is an electric screw lift or a hydraulic cylinder. The lifts 32 are symmetrically arranged, and the number of the lifts 32 is 2 to 4.

[0036] The side positioning mechanism 4 includes a base 41 and a screw 42. The base 41 is fixed to the equipment foundation by anchor bolts, and a number of screws 42 are threadedly connected to the side of the base 41. Manually adjust the connection depth of the screw 42 with the base 41, and the billet abuts against the end of the screw 42, thereby adjusting the position of the billet.

[0037] When the billet needs to be flipped, the billet is lifted by a crane. The billet stops when it descends to be about to contact the lifting centering table 3. The side of the billet is leaned against the screw 42 of the side positioning mechanism 4 to center the billet in the horizontal position, and the billet continues to descend and falls onto the lifting centering table 3. Adjust the lifting height of the lift 32 so that the center of the billet in the thickness direction is lifted to a position consistent with the center of the coil stripping ring 11. The traveling mechanism 24 drives the flipping mechanism 1 to move towards the center, and the billet is sleeved into the through holes 13 of the two coil stripping rings 11. Adjust all the clamping cylinders 15 and screws 14 in the through holes 13 to clamp the billet. The lift 32 of the lifting centering table 3 descends to the zero position. The motor drives the pinion 23 to rotate, and the coil stripping ring 11 rotates to the required angle, and the billet rotating synchronously with it also rotates to the required angle, completing the billet flipping requirement. At this time, the welding operation with the dummy electrode can be carried out. After the welding is completed, operate in the reverse order of the above steps, that is, the lift 32 of the lifting centering table 3 rises, loosen the clamping operation of all the clamping cylinders 15 and screws 14 on the billet in the through holes 13, the traveling mechanism 24 drives the coil stripping ring 11 to move away from the billet, and the billet is lifted by a crane.
