Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has upper and lower I-rule assemblies, and at least one of these assemblies is adjusted to adjust the alignment of the other I-rule assemblies. The present invention relates to a type of rolling mill in which the axis of one roll of one assembly can be tilted horizontally with respect to the axis of one roll of the other assembly.

In such a rolling mill, the purpose of horizontally tilting (i.e. crossing) the axes of the wheels is to obtain a metal strip with the desired contour, thus influencing the shape of the metal strip. It is about J.

Hydraulic or mechanical jacks are generally provided in the side walls of the rolling mill housing to adjust the position of the roll chocks of the rolls, and therefore the horizontal direction of one roll assembly relative to the other. These jacks support the roll chock assemblies in order to adjust the inclination. However, the rolling loads applied to the support chocks assemblies when a rolling mill rolls metal are extremely large, making their adjustment difficult. This was possible only when no rolling was taking place, which increased the operating time of the rolling mill and made it impossible to change the intersection of the rolls during rolling of the metal strip.

The object of the invention is to obtain a rolling mill in which this adjustment of the roll intersection can be carried out during the operation of the one-mole rolling mill.

In accordance with the present invention, the present invention includes a pair of spaced apart housing structures and a "1-luer" hook assembly retained within the housing structures.
1 - Move one side of the assembly against the housing structure, 1 [particularly, 1, 1 part roll and the lower part [1 - means for adjusting the intersection of the bars and each one call bar E to be moved;
A machine stand is not available which is attached to each assembly and is provided with support means etc. to allow for cross-adjustment during use.

Rolla 1 on the other hand! If the assembly has a fixed roll, the support for the other 11-ruer assembly is such that the 1-1-ru of the other 11-ruer assembly can be tilted relative to the fixed roll. It is possible to have additional means for adjusting the assembly.

In another embodiment, τ is G in both 11-le assemblies.
el: 1 to increase the intersection between 10 and el.
Means are provided for moving the block assembly.

In this case, each movable support chock assembly 219 has a support cage disposed between the adjacent horizontal surface of the assembly inner structure of A. Without the support member, the support chock assembly contacts the horizontal surface.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Referring first to FIG. 1, the rolling mill has an upper roll assembly consisting of an upper work roll 2 backed up by an upper backup roll 6. As shown in FIG. Lower back-up [1-Lower roll 1 consisting of a lower work roll 4 backed up by a roll 8! A cabinet is also provided. The ends of the rolls are supported within a roll support chock assembly. The roll support chock assembly is positioned within a window 18 formed by a pair of spaced apart vertical housing structures 20.

As shown in FIG. 1, the two rolls of the upper roll assembly can be tilted horizontally relative to the rolls of the lower roll assembly. That is, the rolls can be "crossed".

Next, refer to FIG. 2. Upper backup row 5- Both ends of the rod 0 are supported within the support gnats 14.

In the support chock 14, a support 10 for a partial work roll 2 is arranged 3; similarly, both ends of the upper back-up roll 8 are supported by support chocks 16, and their support 1. A support chuck 12 for the lower work roll is arranged in one chuck 10.

Inside the wall of each housing forming the vertical plane of the window 18, a hydraulic gill tool 1=22 is arranged. These hydraulic jacks 22 act on the side walls of the chock via pads 24. When considering a typical roll assembly, there is a jack on one side of the roll shaft of one block assembly, and a jack on the opposite side of the assembly roll shaft. But - works together 1
! If the support chocks were brought into contact, the chocks would be moved laterally in the opposite direction within the window of the housing, and the longitudinal axis of the roll assembly would be oriented 1-1 relative to the normal axis of the roll.
), the roll assembly is displaced and tilted horizontally. When the jack acting on one roll assembly is moved in the opposite direction to the jack acting on the other roll assembly, the axis of the roll is at the bottom. [] - crossed so as to be inclined in the horizontal direction with respect to the axis of the wheel.

During operation of the 11 mill, rolling loads are applied through the 11-rule and thus through the support chock assembly to the wide open mill housing. When the rolls are rolling metal, the support chock is exposed to large frictional forces between the top surface of the support chock and the adjacent surface of the housing that the support chock assembly contacts.
It was previously impossible to keep the assembly stationary. The present invention allows the support chock assembly to remain stationary during rolling mill operation by interposing a support member between the surfaces of the support chock assembly and the housing that normally contact each other. It is. The purpose of the support member is to allow movement of the support chock assembly relative to the housing even during operation of the rolling mill.

In the apparatus shown in FIG. 2, the support members consist of a top plate 28 and a bottom plate 30J. The plates 28, 30 are sealed in the edges 1-1 to 32, and a pressurized fluid is placed between the plates. As a fluid (J oil.

When using grease, gas can be used. This support cord 1 part 44
This reduces the distance between adjacent surfaces of the housing, such as the top surface of the support bracket, allowing relative movement between both surfaces.

In FIG.
;1. Between the plates there is a part 1 wear plate 34 and a series of hard steel rollers 36. -fi'1. [1--7
(311), as shown in FIG.

In the embodiment shown in FIG. 4, a pad 40 made of silica or other hard and resilient material is inserted between the base of the chock assembly and the window. A support portion 4A including a pair of soldered plates is arranged.

In this clear afl, I will explain all the examples in all 113
The main objective is to reduce the friction load between the bearing chock alignment and the housing so that the degree of intersection of the 1"1-rule can be adjusted during operation of the rolling mill.7JI ]
The supply of hydraulic fluid being EE to the jack 22 is as follows:
The intersection of the lines and the outline of the strip, ′? A shape meter (sl+apc
It can be controlled by a signal from the meter.

In the apparatus shown in the figure, each roll assembly has a workpiece [1-
Although each assembly consists of a single role and a backup role, each assembly can also contain a single role.

If it is desired to move the lower roll assembly, a support member can be placed between the lower side of the chock of the lower roll assembly and the horizontal plane of the housing window.
