Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 3, the present embodiment provides a roll cassette turnover device for a multi-roll straightener, which includes an apparatus base 1, a driving device 2 and a rotating main shaft 3 mounted on the apparatus base 1, and a turnover frame 4 fixed on the rotating main shaft 3.

The equipment base 1 is fixed on an equipment foundation (for example, the ground), the driving device 2 may be a hydraulic motor or an electric motor, and the driving device 2 is fixedly mounted on the equipment base 1. The driving device 2 is arranged in a straight line or a right angle with the rotating main shaft 3 through a reduction box 5 and is connected with the rotating main shaft 3 in a driving way. Both ends of the rotary main shaft 3 are supported by the machine base through a support bearing and a bearing seat so that the drive device 2 can drive the rotary main shaft 3 to perform a pivoting operation.

The turnover frame 4 is welded and fixed on the rotating main shaft, and a locking hole matched with the roller box 6 is formed in the turnover frame 4, so that the roller box and the turnover frame 4 can be locked by bolts before turnover is carried out, the roller box is guaranteed to be relatively static with the turnover frame in the 180-degree forward and reverse turnover process, and impact is avoided.

In the embodiment, a balance supporting device 7 is further arranged on the equipment foundation, and the position of the balance supporting device 7 on the equipment foundation corresponds to the position of the turnover frame after being reversely turned so as to play a role in supporting, limiting and buffering the turnover frame 4. The balance supporting device 7 is provided with 2 supporting points, and the upper parts of the supporting points are provided with rubber plates 70 so as to reduce the impact between the turnover frame 4 and the balance supporting device 7 when falling.

The roll box turnover device of the multi-roll straightener provided by the embodiment is arranged on the tail side surface of the roll changing device of the straightener, and the turnover frame 4 falls on the balance supporting device 7 when in standby. When the roller of the straightening machine is changed, the roller changing trolley firstly transports the upper roller box 6 out of the operation side of the rack to the side of the turnover frame 4; the driving device 2 drives the rotating main shaft 3 to enable the overturning frame 4 to rotate 180 degrees and fall on the upper surface of the roller box 6, at the moment, a locking screw hole in the overturning frame 4 is aligned with a screw hole in the roller box 6, and the roller box 6 is locked with the overturning frame 4 through a locking bolt. Then, the driving device 2 drives the rotating main shaft to slowly rotate, the overturning frame 4 and the roller box 6 are driven to rotate 180 degrees until the roller box is contacted with the balance supporting device 7, and the roller box 6 faces upwards at the moment, so that subsequent inspection and maintenance can be carried out. And after the roller box 6 is cleaned, the roller box is conveyed into the rolling mill, the overturning device repeats the reverse process of the action, the roller box is conveyed onto the roller changing trolley, and the overturning device finishes the task of assisting in loading a new roller.

The roll box turnover device of the multi-roll straightener, provided by the embodiment, can be arranged on line according to the arrangement condition of the roll changing device of the multi-roll straightener, namely, the roll box turnover device is arranged adjacent to the roll changing device, and can be turned over after being pulled out of the straightener, so that the turnover device is simple and convenient, and the hoisting of a crane is reduced.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
