Description
Technical Field
The utility model relates to a novel conticaster withdrawal and straightening machine belongs to continuous casting technical field.
Background
The withdrawal and straightening machine is an important component of a continuous casting machine, can overcome the resistance of a crystallizer and a secondary cooling device to a casting blank, draws out the casting blank, and can send a dummy bar into a lower opening of the crystallizer. The withdrawal and straightening machine generally comprises a water-cooling frame, an upper roller, a lower roller, a motor, a speed reducer, an oil cylinder, a displacement sensor and a slide rail. The withdrawal and straightening machine has the function of soft reduction, namely, a certain mechanical reduction is applied to the solidification tail end of the continuous casting billet through the contraction of the upper roll gap and the lower roll gap of the withdrawal and straightening machine to compensate the contraction of a solidification body in a two-phase region at the tail end, so that the center porosity is eliminated and the center segregation is reduced. The use under light pressure has very high requirements on the roll gap, and the control precision is within 0.1 mm. The existing withdrawal and straightening machine has the common problem that because the motor and the speed reducer are arranged on one side of the upper roller, the total weight of the motor and the speed reducer is about 5t, the upper roller is stressed on one side, so that the upper roller is inclined, the roller gaps on the left side and the right side are inconsistent, the roller gap on the side provided with the speed reducer is about 1.2mm smaller than the roller gap on the side not provided with the speed reducer, and the control on soft reduction is greatly influenced. When the soft reduction is used, the force of the upper roller acting on the surface of the casting blank is not completely vertical, so that the casting blank is pressed into a trapezoidal blank, and an S-shaped blank is also pressed out when the soft reduction with large reduction is used.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a novel conticaster tension leveler is provided to above-mentioned prior art guarantees that the roller both sides atress is the same on the tension leveler, realizes that the roll gap between roller both sides and the lower roll is unanimous, improves the casting blank quality.
The utility model provides a technical scheme that above-mentioned problem adopted does: a novel withdrawal and straightening machine of a continuous casting machine comprises a rack, wherein an upper roller and a lower roller are arranged in the rack and are arranged in parallel; the upper roller is driven by the lifting device, so that the upper roller can approach to the lower roller to meet the requirement of a roller gap or move away from the lower roller; a speed reducer is arranged on one side of the rack and is in butt joint with the upper roller shaft, and the speed reducer is driven by a motor; a vertical rod is arranged on the other side of the rack, and an upper roller shaft arranged on one side of the vertical rod is provided with an extension section; the extension section is fixedly connected with the vertical rod, a balance weight is arranged below the frame, and the balance weight is fixed at the bottom end of the vertical rod.
The weight of the counterweight is the sum of the weights of the speed reducer and the motor.
Compared with the prior art, the utility model has the advantages of: the utility model provides a novel conticaster tension leveler, sets up the counter weight on the last roller with the speed reducer opposite side, and the weight of counter weight is the weight sum of speed reducer and motor, has guaranteed that tension leveler goes up the roller both sides atress the same, realizes going up the roller gap between roller both sides and the lower roll unanimously, has improved the casting blank quality. Meanwhile, the stability of the withdrawal and straightening machine is improved.
Drawings
Fig. 1 is a schematic view of a novel withdrawal and straightening machine of a continuous casting machine according to an embodiment of the present invention;
in the figure, a motor 1, a speed reducer 2, an oil cylinder 3, a lower roller 4, an upper roller 5, a counterweight 6, a rack 7 and a vertical rod 8 are arranged.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the novel withdrawal and straightening machine for a continuous casting machine in the embodiment comprises a machine frame 7, wherein an upper roller 5 and a lower roller 4 are arranged in the machine frame 7, and the upper roller 5 and the lower roller 4 are arranged in parallel; an oil cylinder 3 is vertically arranged above the upper roller 5, and the oil cylinder 3 drives the upper roller 5, so that the upper roller 5 can approach the lower roller 4 relatively to meet the requirement of a roller gap or be far away from the lower roller 4 relatively. A speed reducer 2 is arranged on one side of the rack 7, the speed reducer 2 is in shaft butt joint with the upper roller 5, the speed reducer 2 is driven by a motor 1, and then the speed reducer 2 drives the upper roller 5 to rotate. A vertical rod 8 is arranged on the other side of the frame 7, and an upper roller shaft arranged on one side of the vertical rod 8 is provided with an extension section; the extension section is fixedly connected with the vertical rod 8. A counterweight 6 is arranged below the frame 7, and the counterweight 6 is fixed at the bottom end of the vertical rod 8. Considering the distance between two withdrawal and straightening machines in the casting flow, the balance weight 6 is arranged below the withdrawal and straightening machines through the vertical rod 8, so that the stability of the withdrawal and straightening machines is improved.
The weight of the counterweight 6 is the sum of the weights of the reducer 2 and the motor 1. The balance weight which is the sum of the weight of the speed reducer and the weight of the motor is arranged on the other side of the upper roll shaft, so that the stress on two sides of the upper roll of the tension leveler is the same, the consistency of roll gaps between two sides of the upper roll and the lower roll is realized, and the stress uniformity and the verticality of the surface of a casting blank are ensured.
This application sets up the counter weight on the last roller with the speed reducer opposite side, and the weight of counter weight is the weight sum of speed reducer and motor, has guaranteed that the stress of last roller both sides of tension leveler is the same, realizes that the roll gap between last roller both sides and the lower roll is unanimous, has improved the casting blank quality. Meanwhile, the stability of the withdrawal and straightening machine is improved.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
