Abstract

The utility model discloses a draw machine which is composed of an upper press roller, a screwdown oil cylinder, draw rollers, a speed reducer and a motor, wherein the length of the upper press roller is equal to or slightly less than that of the draw roller, the screwdown oil cylinder is connected with both ends of the upper press roller, each draw roller and the motor are rotated by the same shaft through the speed reducer, the draw rollers and the speed reducer are connected through a gapless coupling, and the speed reducer and the motor are connected through a gapless coupling. The utility model has the characteristics of no drawing deviation, high motor action precision, small draw machine action deviation, stable rotation and convenient maintenance; a long press roller is directly pressed downwards and completely covered on a copper belt, the centers of the press roller, the draw rollers and the copper belt are superposable.

Description

A kind of hauling machine

One, technical field

The utility model belongs to metal level continuous casting technology field, especially relates to a kind of two long pressure roller hauling machine that drives.

Two, background technology

Hauling machine is one of horizontal casting unit key equipment, particularly double-current strip conticaster requires hauling machine operation precision height, rotating does not have the gap, guarantee the copper material crystalline structure, tractive force is laterally even along copper strips, guarantee not sideslip of copper strips, hauling machine uses single motor-driven mostly at present, be connected with carry-over pinch rolls by gear, last pressure roller is a short roller hinge type hold-down mechanism owing to make and the existence of alignment error, last pressure roller center can not with copper strips center absolute symmetry, copper strips is often drawn partially, drive unit is single motor via reducer, gear is connected with two carry-over pinch rolls, since the existence of the normal sideshake of gear, the spot speed difference of two carry-over pinch rolls, draw finishing, stop, anti-speed and the time deviation of existing when pushing away technological action brings inconvenience for the adjusting process parameter.

Three, summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and adopt that the center that long pressure roller directly depressed, covered fully copper strips, pressure roller, carry-over pinch rolls, copper strips overlaps, do not draw partially, motor action precision height, hauling machine action deviation are little, stability of rotation, hauling machine easy to maintenance.

The purpose of this utility model is achieved in that a kind of hauling machine, is made up of last pressure roller, depress oil cylinder, carry-over pinch rolls, reductor and motor, is characterized in that the length of pressure roller is equal to or slightly less than the length of carry-over pinch rolls, and depress oil cylinder connects the two ends of going up pressure roller.

In order further to realize the purpose of this utility model, can be that every carry-over pinch rolls all rotate by reductor and a motor connecting shaft.

In order further to realize the purpose of this utility model, can be that carry-over pinch rolls are connected by no gap shaft coupling with the between centers of motor with reductor, reductor.

In order further to realize the purpose of this utility model, can be that no gap shaft coupling is an expansion set socket diaxon, expansion set is provided with the expansion set screw.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is the length that the length of upward pressure roller is equal to or slightly less than carry-over pinch rolls, depress oil cylinder connects the two ends of going up pressure roller, last pressure roller adopts long pressure roller directly to depress, last pressure roller laterally covers fully at copper strips and depresses, last pressure roller overlaps with the copper strips center with the pulling force of carry-over pinch rolls to copper strips, and goes up roller bearing frictional force and do not constitute and draw inclined to one side moment; Every carry-over pinch rolls all rotate by reductor and a motor connecting shaft, and the corresponding precision height of motor action, hauling machine finish and draw, stop, counter to push away the technological parameter deviation little; Carry-over pinch rolls are connected by no gap shaft coupling with the between centers of motor with reductor, reductor, no gap shaft coupling is an expansion set socket diaxon, expansion set is provided with the expansion set screw, expansion set and coupled diaxon are tightly fit together, transmit moment of torsion with frictional force, eliminated the gap of bringing fully with key connecting, stability of rotation, easy to maintenance.

Five, specific embodiments

Embodiment 1, a kind of hauling machine, with reference to Fig. 1, be to be provided with two carry-over pinch rolls 3 in the bottom of frame, two carry-over pinch rolls 3 are connected rotation by gear with reductor 4, servomotor 5, and the top of carry-over pinch rolls 3 is provided with pressure roller 1, and the length of last pressure roller 1 is equal to or slightly less than the length of carry-over pinch rolls 3, depress oil cylinder 2 connects the two ends of going up pressure roller 1, and this constitutes a kind of structure of the present utility model.

Embodiment 2, and a kind of hauling machine with reference to Fig. 1, Fig. 2, is on the basis of embodiment 1, and every carry-over pinch rolls 3 all pass through reductor 4 and motor 5 connecting shafts rotate, and other and embodiment 1 are identical.

Embodiment 3, a kind of hauling machine, with reference to Fig. 1, Fig. 3, Fig. 4, be on the basis of embodiment 2, carry-over pinch rolls 3 are connected by no gap shaft coupling 6 with the between centers of motor 5 with reductor 4, reductor 4, no gap shaft coupling 6 is expansion set 7 socket diaxons, and expansion set 7 is provided with expansion set screw 8, and other and embodiment 3 are identical.
