Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an O-ru changing device for a rolling mill, and more particularly.

The present invention relates to a roll changing device that allows a single rolling mill to change the rolls of a plurality of rolling mills.

[Conventional technology]

In the conventional apparatus, each rolling mill is provided with one roll changing apparatus as described in, for example, Japanese Patent Publication No. 60-56564. This is because in a conventional rolling facility equipped with a plurality of rolling mills, rolling operations are carried out simultaneously, and the work rolls must be changed simultaneously and in a short period of time.

[Problem to be solved by the invention]

An object of the present invention is to perform all rolling operations using one roll changing device when there is no need to change the work rolls of multiple rolling mills at the same time, or when there is time available for changing the work rolls of multiple rolling mills. The purpose is to change the rolls of the machine.

[Means to solve the problem]

In order to achieve the above objective, a pedestal ε for loading the upper and lower sets of work rolls, a device for side shifting the pedestal, and a push/pull device for loading and unloading the 5 work rolls into and out of the rolling mill are mounted on the reassembling cart. However, this recombination cart is side-shifted in front of the rolling mill.

[Effect]

Therefore, the work rolls of a plurality of rolling mills can be rearranged using one roll rearranging device.

The effect is very large in terms of economy, space saving, and workability.

Normally, the roll changing device occupies a large space at the front of the rolling mill, which is a huge hindrance to operations and reduces work efficiency.However, since this device can be replaced with just one stand, it saves a lot of space at the front of the rolling mill. , work efficiency is greatly improved. In addition, having only one recombinable trolley means that you only need one set of the mount on the trolley, the side shift device of the mount, and the push/pull device. Since only one set of power sources such as motors and one set of control devices are required, the economical effects are significant.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

In Figures 1 and 2, the stand of rolling mill A is 18,
The stand of rolling mill B is shown as 1b.

Work rolls 2a and 2b are incorporated in each.

In the example of the present invention, an installed rolling mill is used, and intermediate rolls 3a,
3b and reinforcing rolls 4a, 4b are likewise incorporated into the rolling mill. On the other hand, a base is mounted on the recombinant truck 11, and rails 9a,
Alternatively, it has a mechanism that allows it to be moved on 9b. Mounted on this base 10 is a pedestal 5 on which two sets of work rolls can be loaded, and a push/pull device 7 having a drive device (not shown) for moving the work rolls in and out of the rolling mill.

In FIG. 2, a new work roll 2c and an intermediate roll 3c are also loaded. This frame 5 is side-shifted by a cylinder 6. Further, the recombination cart 11 is also moved on the fixed guide 13 by the traversing cylinder 12, and can be moved to the front of the rolling mill A or B. In FIG. 3, the recombination cart 11 is in a state of being moved sideways toward the rolling mill A side. In FIG. 4, the base 10 has advanced to the vicinity of the rolling mill B, and the work roll 2b is seen from inside the rolling mill.

It is pulled out onto the pedestal 5 by the push/pull device 7, and then the pedestal 5 is pulled out.
Thereafter, the work roll 2c is side-shifted, and the new work roll 2c is about to be installed in the rolling mill.

By configuring the roll changing device in this way, the work rolls and intermediate rolls of two rolling mills can be changed using one changing cart.

In this explanation, a cylinder is used to move the recombinable truck, base, frame, etc., but it is clear that this can be done in the same way using other methods, such as electric motors, hydraulic motors, etc. Furthermore, even if the rolling mill is large or larger, it is obvious that it can be used with a recombinant carriage of -10 or higher.

〔Effect of the invention〕

According to the present invention, it is possible to change the rolls of a plurality of rolling mills using a single changing cart, which saves space.
The economic effects are significant.
