[0002] In front of the vertical push furnace on the aluminum plate and strip hot rolling production line, an aluminum ingot centering device needs to be installed. After the ingot reaches the loading position of the vertical push furnace, the centering device will be activated to align the width center of the ingot with the center of the roller to meet the production requirements of subsequent equipment, thereby smoothly pushing the ingot into the heating furnace.

[0003] Our company's existing equipment is as shown in the attached figure of the instruction manual Figure 5 and Figure 6 As shown in the figure, the centering cylinder is placed below the roller table, and the centering clamping plate is placed above the roller table. During operation, due to the long resistance arm and the poor overall rigidity of the clamping plate, the clamping plate is prone to bending to the sides, resulting in the failure of the centering function and failure to meet the requirements of subsequent processes. To this end, we propose a centering device for aluminum ingots in front of a hot rolling vertical pusher furnace. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an aluminum ingot centering device in front of a hot rolling vertical push furnace. The clamping force of the centering cylinder acts directly on the center of the centering roller through two car bodies.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 The utility model provides a technical solution: a centering device for aluminum ingots in front of a hot rolling vertical push furnace. The device abandons the original structure, removes several centering rubber rollers on both sides of the lifting chassis, and then arranges a new centering device in this space. The new centering device specifically includes a lifting chassis 1, one side of the lifting chassis 1 is the operating side, and the other side is the transmission side. A cylinder seat 10 is provided on the transmission side of the lifting chassis 1, and a centering oil cylinder 9 is installed on the cylinder seat 10. A rail 2 is provided on the operating side and the transmission side of the lifting chassis 1, wherein an operating roller is provided on the rail 2 on the operating side. The side car body 3 has a drive-side car body 8 that is movable within the drive-side track 2. The two car bodies 8 are arranged opposite each other and symmetrically. Centering rollers 7 are rotatably installed on both the drive-side car body 8 and the operating-side car body 3. The side surface of the drive-side car body 8 is fixedly connected to the movable end of the centering cylinder 9. A synchronous transmission device is provided between the drive-side car body 8 and the operating-side car body 3. The synchronous transmission device is used to drive the centering cylinder 9 to drive the drive-side car body 8 and the operating-side car body 3 toward each other. The ingot is then pushed through the centering roller 7 and its width center is aligned with the center of the roller table, achieving the centering function. The clamping force of the centering cylinder 9 acts directly on the center of the centering roller 7 through the two car bodies. There is no resistance arm, and the overall rigidity is reliable, ensuring the effectiveness of the centering function.

[0020] One of the preferred technical solutions of the synchronous transmission device: it includes racks 5 respectively arranged on the lower part of the opposite side of the transmission side car body 8 and the operating side car body 3, and two rack rails 4 are symmetrically arranged on the upper surface of the lifting chassis 1. The two racks 5 are respectively slidably arranged in the corresponding rack rails 4, and a gear 6 is rotatably arranged between the upper surface of the lifting chassis 1 and the two rack rails 4. The two racks 5 are both engaged with the gear 6, and the two racks 5 are centrally symmetrically arranged with the center of the gear 6 as the center of symmetry. When the centering cylinder 9 drives the transmission side car body 8 to move, the transmission side car body 8 drives the rack 5 connected thereto to move toward the middle, and the rack 5 drives the other rack 6 to move toward or away through the gear 6, so that the centering rollers 7 on the two car bodies move toward or away, realizing synchronous movement and quickly centering the ingot.

[0021] The original design structure achieves cylinder synchronization through a hydraulic synchronization circuit. Due to the unstable factors in the hydraulic system, the cylinder extension and contraction amounts are inconsistent, so the centering accuracy is not high. This application uses a gear rack mechanism to achieve centering. The stability of the mechanical structure ensures that the centering accuracy meets the requirements. At the same time, the movement of the car body and rack is constrained by the car rail and rack rail to ensure reliable movement.

[0022] When the ingot reaches the centering position, an external proximity switch sends a signal, actuating the solenoid valve. The piston rod of the centering cylinder 9 pushes the transmission-side body 8, whose lower portion is connected to the transmission-side rack 5, thereby driving the transmission-side rack 5 to move. The motion is transmitted to the operating-side rack via the centrally arranged gear 6, which in turn drives the operating-side body 3 to move in the opposite direction. The centering rollers 7 on both sides clamp the ingot to achieve the centering function. After the ingot is centered, the proximity switch sends a signal, actuating the solenoid valve, and the piston rod of the centering cylinder 9 retracts, driving the centering rollers 7 on both sides to open wider, preparing for the next centering cycle.

[0023] This application also provides another embodiment, please refer to Figure 4 This embodiment is roughly the same as the previous embodiment, with the difference being that a rack rail mounting bracket 11 is fixedly provided on the lower surface of the rack rail 4, and a plurality of screw holes are provided on the upper surface of the rack rail mounting bracket 11 and the upper surface of the lifting chassis 1, and fixing bolts 12 are connected with the inner threads of the screw holes. The rack rail mounting bracket 11 and the rack rail 4 are fixed to the lifting chassis 1 by the fixing bolts 12. When the rack 5 or the rack rail 4 is worn or the accuracy deteriorates due to long-term work, it can be easily removed for replacement or maintenance.

[0024] The preferred technical solution is that a limit groove 13 is respectively provided on the upper and lower sides of the interior of the rack rail 4, and the rack 5 is provided with a limit portion corresponding to the limit groove 13 in the internal part of the rack rail 4, that is, the cross-sectional shape of the limit groove 13 is "T"-shaped, and the cross-sectional shape of the rack 5 is "I"-shaped, so that the rack 5 can only move forward and backward inside the rack rail 4 along the telescopic direction of the centering cylinder 9, further ensuring the movement reliability.

[0025] A further preferred technical solution is that the rack 5 is provided with a groove on one side surface inside the rack rail 4, and a number of rollers 14 are evenly rotated in the groove. When the rack 5 moves in the rack rail 4, the friction can be greatly reduced by the rollers 14, so that it is easier to move and drive another rack 5 to move through the gear 6, making the centering operation more convenient and reducing wear, which is conducive to extending the service life of the device.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
