The utility model provides a technical scheme that its technical problem adopted realizes like this:
a casting blank centering guide device of a vertical round billet continuous casting machine comprises a base fixed on an equipment foundation, a hydraulic cylinder fixed on the base, a sliding frame connected to the hydraulic cylinder and sliding in the base, a guide roller support fixed on the sliding frame and a guide roller installed on the guide roller support, wherein the base, the sliding frame and the hydraulic cylinder are horizontally and symmetrically arranged on two sides of the axis of a casting blank in pairs.
And a channel for the sliding frame to horizontally slide is formed in the base.
The sliding frame, the guide roller support and the guide roller are in rigid connection, and when the hydraulic cylinder stretches, the sliding frame, the guide roller support and the guide roller synchronously and horizontally stretch and move along with the hydraulic cylinder.
The hydraulic cylinder is characterized in that a displacement sensor is arranged in the cylinder body of the hydraulic cylinder, the roller surface distance of the two symmetrically arranged guide rollers is set to be 2mm larger than the diameter of a casting blank, the distance is measured and controlled by the displacement sensor arranged in the hydraulic cylinder, and the distance is kept unchanged in continuous casting production.
The casting blank centering guide devices are arranged above the casting blank drawing rollers of the continuous casting machine, and the number of the casting blank centering guide devices is not less than 2.
The beneficial effects of the utility model are that, the device simple structure and easy operation maintenance have good centering guide effect, can avoid in the vertical round billet continuous casting production casting blank bending deformation to lead to the skew perpendicular decurrent knockout direction of casting blank advancing direction.
Drawings
Fig. 1 is a schematic structural diagram of a casting blank centering guide device of a vertical round billet continuous casting machine.
Shown in the figure are: 1. a base; 2. a slide frame; 3. a hydraulic cylinder; 4. a guide roller; 5. a guide roller support; 6. and (5) casting a blank.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, a casting blank centering guide device of a vertical round billet continuous casting machine is fixed on an equipment base above a casting blank roller of the continuous casting machine, and is formed by combining a base 1, a sliding frame 2, hydraulic cylinders 3, guide rollers 4 and guide roller supports 5 which are horizontally and symmetrically arranged at two sides of a casting blank 6, wherein two hydraulic cylinders 3 are fixed in each base 1, the end parts of the hydraulic cylinders 3 are connected with the sliding frame 2, a displacement sensor for measuring the stroke of the hydraulic cylinders is arranged in the cylinder body of each hydraulic cylinder 3, the two hydraulic cylinders 3 can synchronously push and pull the sliding frame 2, the end parts of the sliding frame 2 are provided with the guide roller supports 5, the guide rollers 4 are arranged on the guide roller supports 5, the guide roller supports 5 are rigidly connected with the sliding frame 2 and the guide rollers 4, when the two hydraulic cylinders 3 push and pull the sliding frame 2, the guide rollers 4 stretch along with the sliding frame, and the guide rollers 4 can rotate on the guide roller supports 5, cooling water passages are provided inside the guide rollers 4 and the guide roller holders 5.
In the production of the vertical round billet continuous casting machine, the roll surface spacing of two guide rolls 4 which are symmetrically arranged is set to be 2mm larger than the diameter of a casting blank 6, and the spacing is measured and controlled by a displacement sensor which is arranged in a hydraulic cylinder 3 and is kept constant in the continuous casting production. When the casting blank 6 passes through the casting blank centering guide device, if the bending deformation of the casting blank 6 exceeds 1mm, the roller surface of the guide roller 4 is tightly attached to the casting blank 6, and the guide roller 4 keeps the distance unchanged under the hydraulic acting force of the hydraulic cylinder 3, so that the casting blank 6 is forcibly centered and guided, the bending deformation of the casting blank 6 is less than or equal to 1mm, and the effect of keeping the vertical downward blank discharging direction of the casting blank 6 is achieved.
Because vertical round billet caster has the multiunit to draw the base roller, this centering guider can arrange simultaneously above the multiunit roller, and its quantity is no less than two sets ofly, sets up the guide roller interval that corresponds according to the actual diameter of casting blank during the use to the casting blank bending deformation leads to the skew problem of predetermined direction of casting blank advancing direction in avoiding production.
The device is symmetrically arranged on two sides of the vertical axis of the casting blank. The middle of the base is provided with a channel for the sliding frame to horizontally slide, the two sides of the base are provided with positioning holes, the trunnion of the hydraulic cylinder penetrates through the positioning holes to be fixed on the base, and the two sides of the sliding frame are fixed with the piston rod of the hydraulic cylinder, so that the base, the hydraulic cylinder and the sliding frame jointly form a mechanism capable of horizontally stretching and moving. The end part of the sliding frame is fixed with a guide roller support, and a guide roller is arranged on the guide roller support, so that the horizontal telescopic movement of the hydraulic cylinder synchronously controls the horizontal telescopic movement of the guide roller. The guide roller is a cylindrical roller, the guide roller and the guide roller support are internally provided with cooling water channels, and the circulating cooling water is utilized to reduce the temperature of the guide roller and the guide roller support, so that the requirement of use in a high-temperature environment is met. The casting blank centering guide device is fixed on an equipment base above a continuous casting machine casting blank drawing roller, and at least two sets of casting blank centering guide devices are arranged according to the roller arrangement condition of the continuous casting machine casting blank drawing machine. And when the bending deformation of the casting blank is more than or equal to 1mm, the guide rollers cling to the casting blank and perform forced centering guide on the casting blank, so that the casting blank keeps a preset vertical downward blank discharging direction.
