In order to achieve the above object, the utility model discloses an aspect provides a rolling mill box, include the box and set up the input shaft in the box, the both ends of input shaft stretch out respectively the relative both sides of box to the input that can be connected with gearbox power is all set to at its both ends.

Preferably, both input ends of the input shaft are provided with external splines for power connection with the gearbox.

Preferably, the input end of the input shaft is connected with the gearbox through a coupling.

Preferably, one of the input ends of the input shaft is used for being in power connection with a gearbox, and the other input end cover is provided with a protective cover which is detachably connected with the box body.

Preferably, the input shaft comprises a first input shaft and a second input shaft assembled in parallel.

The utility model discloses the second aspect provides a rolling mill, including foretell rolling mill case.

The utility model discloses following beneficial effect has:

the utility model provides an input shaft of rolling mill case adopts and link up the setting, and its both ends all stretch out the box and all set the input that can be connected with gearbox power to. When the rolling mill adopting the rolling mill box structure is arranged on a left line, the left input end of the input shaft is in power connection with the left line gear box; when the input shaft is arranged on the right line, the right input end of the input shaft is in power connection with the right line gearbox. Therefore, the rolling mill can be simultaneously suitable for the installation of the left line and the right line, the exchange of the left line rolling mill and the right line rolling mill is realized, and the left and right steel rolling production lines only need one spare rolling mill, so that the number of spare rolling mills is effectively reduced, and the production cost is reduced.

Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the following further detailed description of the embodiments of the present application with reference to the drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 2, 3 and 4, a rolling mill box comprises a box body 101 and an input shaft 102 arranged in the box body, wherein two ends of the input shaft respectively extend out of two opposite sides of the box body, and two ends of the input shaft are respectively arranged as an input end 102a capable of being in power connection with a gearbox. The rolling mill 1 comprises the above-described mill housing.

The motor drives the input shaft 102 to rotate, the input shaft 102 is matched with the transmission structure of the rolling mill 1, then the transmission structure is matched with the roller to drive the roller to rotate so as to roll and form the steel, the structure and the working principle of the device are the same as those of the prior art, and the device is not repeated herein, and one embodiment of the device can refer to the content disclosed in the prior patent application (with the publication number being CN205270349U) of the applicant.
