Abstract
The utility model discloses a double-motor driving device of a pin-lift car of a piercing mill, which resolves the technical problems that the existing single motor rack driving device has large starting inertia and slow working pace, and is not suitable for rolling large blank steel tubes. The double-motor driving device comprises a motor coupler braking device, a reduction box, a coupler, gearsand racks, wherein the working surface of the gears meshes with that of the racks to provide power to lead the pin-lift car to run; the driving motors are arranged in a parallel or tandem manner, drive the gears to mesh with the racks through the coupler braking device and then through the coupler, accordingly the motors drive the pin-lift car; the pin-lift car is driven smoothly, can position accurately, have high running speed and heavy load, and the requirement on high speed production of automatic production lines can be met. Besides, the double-motor driving device of a pin-lift car of apiercing mill has simple structure, convenient control and low cost.
Description
Technical field
The utility model relates to a kind of mechanical driving device, the transmission gear for electric motor of the punching machine post rod dolly during particularly a kind of hot rolled seamless steel tube is produced.
Background technology
It is to be formed by rolled by piercing mill that hot rolling does not have the steel pipe of meeting, the basic craft course of drilling/rolling is: form a blind bore type by roll, guide plate, top, high-temperature metal carries out continuous modification in the zone that this pass constitutes, finally shut out hollow hollow billet from solid pipe.Wherein, roll, guide plate are installed according to the technological requirement relative fixed, and the top is installed on the push rod, with the action request of rolling cycle, are rolled the change of position and work back bit period.Its operational outfit is exactly the ejector rob trolley provided device that is connected with the push rod afterbody.Ejector rob trolley provided is to be driven by motor, realizes ejector rob trolley provided control.At present, the type of drive of domestic general ejector rob trolley provided device has: single motor steel wire rope driving, single motor chain drive, single motor rack drives.The characteristics of this structure are that cost is low within the specific limits, have drive steadily, equipment is simple, control advantage easily, thereby is widely used in conventional piercing mill of seamless steel tube group.But single motor-driven also has certain shortcoming: the one, and starting inertia is big, cause acceleration constantly decay in starting process of system, cause the speed of ejector rob trolley provided device low, require more and more faster for modern steel pipe industry rolling rhythm, efficient requires high, can not satisfy its requirement; The 2nd, the load of bearing is little, has certain limitation for present rolling big blank steel pipe.
Summary of the invention
It is big that the utility model has solved existing single motor rack drives device starting inertia, and work rhythm is slow and be not suitable for the technical problem of rolling big blank steel pipe.
The utility model overcomes the above problems by following scheme:
The Belt Driven by Double Motor device of punching machine post rod dolly mainly consists of the following components: motor coupler brake apparatus, reductor, shaft coupling, gear, tooth bar.The working face engagement of wheel and rack is for ejector rob trolley provided operation provides power.Motor mode arranged side by side with two or tandem arranges that by the shaft coupling brake apparatus, reductor is given gear by the shaft coupling transmission again, and the wheel and rack engagement realizes ejector rob trolley provided driving.
The Belt Driven by Double Motor device of punching machine post rod dolly, comprise drive motors, shaft coupling brake apparatus, reductor, shaft coupling, gear with the ejector rob trolley provided tooth bar that is connected, the described and ejector rob trolley provided tooth bar that is connected is in the same place with first gear and second gears engaged respectively; First gear links together by first shaft coupling, first reductor, the first shaft coupling brake apparatus and first drive motors successively; Second gear links together by second shaft coupling, second reductor, the second shaft coupling brake apparatus and second drive motors successively.
The Belt Driven by Double Motor device of punching machine post rod dolly, comprise drive motors, shaft coupling brake apparatus, reductor, shaft coupling, gear with the ejector rob trolley provided tooth bar that is connected, described and the ejector rob trolley provided tooth bar that is connected and first gears engaged are together, first gear links together by first shaft coupling, first reductor, the first shaft coupling brake apparatus and first drive motors successively, and first drive motors also is cascaded with the 3rd drive motors by the 3rd shaft coupling.
The utility model has satisfied the needs of the rolling big blank of modern hot rolled seamless steel tube, has realized smooth drive, accurate positioning, and speed of service height, load is big, has satisfied the requirement of the high-speed production of automatic assembly line, and is simple in structure, and control is convenient, and is with low cost.
Description of drawings
The structural representation that Fig. 1 motor of the present utility model is arranged in two modes arranged side by side
The structural representation that Fig. 2 motor of the present utility model is arranged with two tandem moor
The specific embodiment
The Belt Driven by Double Motor device of punching machine post rod dolly, comprise drive motors, shaft coupling brake apparatus, reductor, shaft coupling, gear with the ejector rob trolley provided tooth bar that is connected, the described and ejector rob trolley provided tooth bar that is connected meshes together with first gear 5 and second gear 6 respectively; First gear 5 links together by first shaft coupling 4, first reductor 3, the first shaft coupling brake apparatus 2 and first drive motors 1 successively; Second gear 6 links together by second shaft coupling 7, second reductor 8, the second shaft coupling brake apparatus 9 and second drive motors 10 successively.
The Belt Driven by Double Motor device of punching machine post rod dolly, comprise drive motors, shaft coupling brake apparatus, reductor, shaft coupling, gear with the ejector rob trolley provided tooth bar that is connected, described and the ejector rob trolley provided tooth bar that is connected and first gear 5 mesh together, first gear 5 links together by first shaft coupling 4, first reductor 3, the first shaft coupling brake apparatus 2 and first drive motors 1 successively, and first drive motors 1 also is cascaded with the 3rd drive motors 12 by the 3rd shaft coupling 11.
Under the certain situation of power of motor, adopt bi-motor (this moment, bi-motor power sum equaled single power of motor), the moment of inertia is little, reduce electromechanical time constant, rotating speed rises or descends fast more, has improved the speed of service, reduce inertia, guarantee ejector rob trolley provided stopping and accurate positioning reposefully; Improved the speed of service simultaneously; And the mechanical property after bi-motor is synthetic is harder than the mechanical property of single motor transmission, and the load that it can be born is bigger.
