Description

Supporting device for horizontal motor of feeding mechanism of seamless steel pipe cold rolling mill

Technical Field

The utility model relates to a ferrous metallurgy machinery especially relates to a supporting arrangement of horizontal motor of feed mechanism when being applied to blank pipe feed operation when seamless steel pipe cold rolling production.

Background

At present, steel production enterprises often use a two-roller periodic seamless steel tube cold rolling mill when producing seamless steel tubes to carry out cold deformation processing on blank tubes at normal temperature, and the two-roller periodic seamless steel tube cold rolling mill is the most widely applied seamless steel tube cold rolling mill due to the characteristics of compact structure, large rolling force, high productivity and the like.

The two-roller periodic seamless steel tube cold-rolling mill mainly comprises a power mechanism, a transmission mechanism, a rolling mechanism, a feeding and rotating mechanism, a mandrel chuck mechanism, a lathe bed supporting mechanism, a hydraulic system, an electrical control system, a lubricating and cooling system, a feeding and blanking mechanism and the like. The feeding and blanking mechanism is divided into two parts, namely feeding and blanking, which are relatively independent, and the feeding mechanism is used for transmitting a seamless steel pipe blank tube to be rolled and deformed into a feeding groove from a feeding rack and pushing the blank tube into an intermediate lathe bed under the driving of mechanical power. The blanking mechanism is used for conveying the finished pipe which is rolled and deformed by the rolling mechanism into the material feeding groove from the finished product groove. Due to the functional characteristics of the mechanism, the working condition requirements of the feeding and blanking mechanism are determined, and the feeding, rolling and feeding-out fixed-position transmission of the blank pipe and the finished pipe can be accurately, safely and smoothly completed.

The material feeding part of the material feeding and blanking mechanism mainly comprises a transmission device, a material feeding rack, a material feeding groove, a material pushing device, a material feeding device, a hydraulic motor and the like. The transmission device comprises a transmission shaft, a double-row chain wheel, a transmission chain, a coupling, a speed reducer, a motor and the like. When the feeding device is used, the hydraulic motor drives the feeding device, the blank pipe is conveyed into the feeding groove from the feeding rack by utilizing the lever principle, the transmission device drives the material pushing device to push the blank pipe in the feeding groove, and the transmission chain drives the material pushing rod to move horizontally to push the blank pipe into the middle lathe bed. The transmission device of the whole feeding mechanism has compact structure, stable operation and strong bearing capacity, and can meet the fixed-point feeding function of the blank tubes of various specifications.

With the feedback of production workers in actual production practice, certain defects still exist in the existing transmission device of the feeding mechanism, for example, an LG-220H cold rolling mill adopts a cycloid gearbox, a horizontal motor is directly installed on the end face of the gearbox, and the motor and the gearbox are fixed through 6M 12mm screws, so that the following problems are caused:

1) the vertical support measures of the horizontal motor are missing:

after a certain period of time, 6 screws can loosen, and particularly, the 6 screws are affected by vibration during rolling, so that the loosening is aggravated, even the screws escape and fall off, at the moment, the motor which is fixed on the end face of the speed reducer only through the 6 screws can cause the motor to be inclined outwards due to the action of factors such as dead weight, kinetic energy generated during high-speed rotation of the motor and the like, the motor shakes during high-speed operation, faults such as screw pulling-off, breakage of a threaded hole of the speed reducer and an ear seat of the motor and the like can be caused during serious conditions, and potential safety hazards of equipment are caused;

2) the sight has a blind area, and is not easy to observe in daily production:

the mounting position of the feeding transmission device is positioned between the feeding rotary gear box and the feeding bench, and the whole transmission device is mounted in a pit with the depth of 300mm and is positioned in a sight blind area of an operator in terms of a mounting station. The operation conditions of a motor and a transmission of a feeding transmission device cannot be observed when the equipment is operated at a normal station, even if the screw loosening phenomenon occurs, an operator cannot find the operation conditions at the first time, and the equipment spot inspection operation maintainers perform regular inspection, so that the time difference between a fault and a detection operation exists, and the potential fault hazard cannot be found and eliminated in time;

3) lack of source treatment measures:

after the failure of the feeding transmission device occurs, although the using function of the feeding mechanism can be recovered by replacing the transmission and the motor, the failure hidden trouble can not be thoroughly eliminated from the source, the problem of effective supporting in the vertical direction of the motor is solved, the failure is frequent along with the release of the equipment capacity, the orderly operation of cold rolling production is influenced to a certain extent, and meanwhile, the consumption of equipment maintenance resources (human resources and material cost resources) is increased.

In conclusion, the feeding mechanism of the conventional two-roller periodic seamless steel tube cold rolling mill has certain defects, cannot meet the requirements of safe, stable and efficient feeding and conveying operation production of a blank tube, and becomes a difficult point in operation and maintenance of field equipment. Aiming at the existing problem points, the working condition characteristics of the feeding and blanking mechanism are combined, corresponding technical improvement is implemented, the requirement of stable, accurate and safe feeding of blank pipes, especially large-size blank pipes, is met, the operation quality of equipment is improved, the overhaul operation load and the material consumption are reduced, the labor intensity is reduced, and the intrinsic safety and the functional precision construction of the equipment are promoted.
