Abstract

The utility model provides a rotating disc type roller replacing vehicle which comprises a support. A main shaft, a rotating disk, two roller grooves and a motor are arranged on the support. One end of the main shaft is fixedly connected on the support and can rotate around the axis of the main shaft. The rotating disk is fixedly connected at the other end of the main shaft. The two roller grooves are both fixedly connected on the rotating disk and are symmetrically arranged relative to the main shaft. The bottom face of each roller groove is perpendicular to the axis of the main shaft. The rotating disc type roller replacing vehicle has the advantages that three positions are reduced to two positions, and the occupied position of a transverse oil cylinder is omitted so that the size of the transverse plane of the whole roller replacing vehicle is reduced, occupied space is reduced correspondingly, and the roller replacing vehicle is suitable for roller replacing operation on rolling mills of different models; steps for replacing rollers are decreased, and work efficiency is improved; and the structure is simple and operation is convenient.

Description

The rotating disc type roll changing carriage

Technical field

The utility model relates to the field, auxiliary equipment place of milling train, relates in particular to a kind of changing rig of milling train.

Background technology

After roll in the milling train used a period of time, the fineness on surface will reduce, and causes rolling steel band Quality Down, so need periodic replacement.Traditional roll-changing method is to carry out the push-and-pull replacing with artificial and the driving breaker roll that matches, but this method wastes time and energy, and danger coefficient is high, and As time goes on the continuous progress of technology, the method is eliminated gradually.Then, begin again to make special changing machine in the actual production, thereby change roll with the higher method of mechanization degree, increase work efficiency, reduce dangerous.

Roll changing carriage commonly used usually adopts three stations, and provides power push-and-pull roll to replace by horizontal and vertical two oil cylinders at present.First old roll is pulled out from frame by intermediate stations during work, then the lateral oil cylinder working pushes intermediate stations with new roll, restarts the longitudinal oil cylinder working, and new roll is pushed frame from middle station, thereby finishes the operation of changing roll.

The shortcoming of existing roll changing carriage is: because roll changing carriage needs three stations, add the occupy-place of horizontal oil cylinder, so that whole roll changing carriage plane of structure size is very large, take up room and also increase thereupon, and in the actual production, the layout of a lot of milling trains is very compact, and roll changing carriage plane of structure size can cause some milling train to carry out roll change with the use roll changing carriage when very large, bring great inconvenience to production work.And when changing roll in producing, machine can't be worked, and the new roll such as only has to change and completely just can work on, so the time of changing roll is shorter, and is less to the loss that production causes, the time of changing now roll is longer, and efficient is low, is unfavorable for reducing production costs.

The utility model content

Technical problem to be solved in the utility model is, a kind of rotating disc type roll changing carriage is provided, to solve existing aborning roll changing carriage excessive, the inefficient problem of roll change that takes up room.

In order to address the above problem, the utility model provides a kind of rotating disc type roll changing carriage, comprises support, and support is provided with main shaft, rotating disk, two roller grooves and motor, and described main shaft one end is fixed on the support, and can rotate around axis; Described rotating disk is fixed in the main shaft other end; Described two roller grooves all are fixed on the rotating disk, and two roller grooves are symmetrical arranged with respect to main shaft, and roller groove bottom and main-shaft axis are perpendicular.Owing to the axis of two roller grooves about main shaft is symmetrical arranged, as long as with 180 ° of turntable rotations, the position of two roller grooves can exchange during roll change.

When needing to change roll in the production, its job step is as follows:

1, new roll is placed in the roller groove of rotating disc type roll changing carriage, the rotating disc type roll changing carriage is pushed into by the frame subsequently;

2, another sky roller groove is aimed at the old roll position that needs replacing, old roll is drawn in this roller groove;

3, starter motor, rotating spindle and rotating disk, so that 180 ° of turntable rotations, the roller groove at new roll place goes to the just now position of old roll place roller groove, namely faces the position on the frame of original old roll place;

4, new roll is pushed in the frame, finish roll change work.

Further, described rotating disk is fixed in the main shaft upper end by screw.

Further, described roller groove is fixed on the rotating disk by screw.

The utility model has the advantage of:

1, three stations are reduced to two stations, add the occupy-place that has saved horizontal oil cylinder, so that whole roll changing carriage plane of structure size reduction, take up room also reduces thereupon, is applicable to the mill roll work of different model;

2, reduce the step of changing roll work, improved operating efficiency;

3, simple in structure, easy to operate.

Description of drawings

Fig. 1 is the utility model rotating disc type roll changing carriage structural representation;

It is as follows that number in the figure represents parts:

1, support;

2, main shaft;

3, rotating disk;

401, the first roller groove;

402, second roller groove;

5, motor.

The specific embodiment

The specific embodiment of the rotating disc type roll changing carriage that the utility model is provided below in conjunction with accompanying drawing elaborates.

Be illustrated in figure 1 as the utility model structural representation.Can find out from above-mentioned figure, a kind of rotating disc type roll changing carriage of the utility model comprises support 1, main shaft 2, rotating disk 3, roller groove and motor 5.Described main shaft 2 is fixed on the support 1, can rotate around axis, and vertical with horizontal plane; Described rotating disk 3 is fixed in main shaft 2 upper ends by screw; Described roller groove has two, be respectively the first roller groove 401 and second roller groove 402, the first roller groove 401 and second roller groove 402 also are fixed on the rotating disk 3 by screw, two roller grooves are symmetrical arranged with respect to main shaft 2, the bottom surface of roller groove parallels with horizontal plane, and namely roller groove bottom and main shaft 2 axis are perpendicular.

When needing to change roll in the production, its job step is as follows:

1, new roll is placed in the second roller groove 402 of rotating disc type roll changing carriage, the rotating disc type roll changing carriage is pushed into by the frame subsequently;

2, the first roller groove 401 is aimed at the old roll position that needs replacing, old roll is drawn in this roller groove;

3, starter motor 5, rotating spindle 2 and rotating disk 3, so that rotating disk 3 Rotate 180s °, second roller groove 402 goes to the just now position at the first roller groove 401 places, namely faces the position on the frame of original old roll place;

4, new roll is pushed in the frame, finish roll change work.

The utility model is reduced to two stations with three stations, adds the occupy-place that has saved horizontal oil cylinder, so that whole roll changing carriage plane of structure size reduction, take up room also reduces thereupon, is applicable to the mill roll work of different model; And simple in structure, easy to operate, greatly improved operating efficiency.

The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
