Abstract

PURPOSE:To provide a double rolling/universal rolling mill which has improved roll changeability by fixing an intermediate housing to a sole plate, providing an outer housing movably, and providing a yoke contg. a vertical screw down device attachably and detachably. CONSTITUTION:A work side (WS) outer housing 1 and an intermediate housing 3 are fixed to a sole plate 4. A drive side (DS) outer housing 2 is supported freely slidably on a sole plate 4, and is connected to the housing 1 by means of a soft cylinder 16. The cylinder 16 is moved to move the housing 2 in parallel with the housing 1 and to displace the same according to the cylindrical length of the horizontal roll. The housing 2 is fixed to the housing 3 by a clamping cylinder 17, and the housing 2 is moved to change over universal rolling to double rolling. A yoke 8 contg. a screw down device for a vertical roll is made attachable and detachable to make roll changing easy.

Description

【発明の詳細な説明】 本発明は、二重圧延機も兼用できる子ニバーサル圧延機
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a secondary rolling mill that can also be used as a double rolling mill.

基の圧延機で兼用させることが年来の念願で種々の工夫
がなされてきたが、実用的で秀れたものが出ていない。In one-form rolling mills, the rolling mills used are roughly divided into two types depending on the product being manufactured. That is, there is a universal rolling mill for rolling II section steel, and a double rolling mill for rolling general sections such as angle nets. It has been a long-cherished desire to use a single rolling mill for these two types of rolling mills, and various efforts have been made to do so, but nothing that is practical or superior has yet been developed.

が一基の圧延機でユニバーサル圧延機と二重圧延機を兼
用させることを呟む要因となっていた。This is due to the fact that the universal rolling mill used for H-beam steel can perform multiple passes of forward and reverse rolling in the same passage by rolling down the horizontal rolls and vertical rolls, and in this case, the horizontal rolls and vertical rolls are rolled down. While the rolling mill has the ability to withstand such rolling reaction forces, - the double rolling mill used for rolling ship shape steel uses only horizontal rolls and performs groove rolling, so it has a large number of hole shapes; The rolling mill must be able to withstand the strong rolling reaction force, that is, the two types of rolling mills must have different combinations of whirl, ``horizontal and vertical'' and ``horizontal only.''■ The horizontal roll body There are significant differences in length. ■ There are functional differences such as the rolling reaction force acting differently between "horizontal and vertical" and "horizontal only." This was a reason for people to murmur about using both the universal rolling mill and the double rolling mill.

る。FIG. 2 is a front view of FIG. 1, and (a) in FIG. 2 shows the case of universal rolling, and (b) shows the case of double rolling. First, in Figure 2 (A), (2) is the DS (drive side) outer housing, which is slidably supported at its lower part by the sole plate (4), and which uses fluid pressure to shift. Cylinder(
16) is connected to the WS' outer housing t1), and by the operation of the cylinder (16), the DS outer housing (2) can move parallel to the WS outer housing +11, and can be displaced according to the length of the horizontal roll. There are 4 things that can be done. Furthermore, (17) is a clamp cylinder, and the DS outer housing (2) is fixed to the intermediate housing (3) by the clamp cylinder.

ることである。The state in which the DS outer housing (2) is moved and changed from universal rolling to double rolling with the above configuration is shown in (b) of Figure 2. What should be noted here is that during rolling, the DS outer housing (2) (2) is shifted, but the rolling reaction force is completely absorbed as an internal force by the WS outer housing t1>, the DS after housing (2), and the intermediate housing (3), respectively, causing the DS outer housing (2) to shift. and that it has nothing to do with the absorption of reaction force.

Figure 3 (a) is a view taken along line A-'A in Figure 2 (a) showing the case of universal rolling, where (5) is the upper horizontal roll and (12) is the upper horizontal roll chock. be. On the other hand, (b) in Figure 3 is the DS outer housing (2).

いる。This is a method that can be easily replaced, just like the double rolling mill used by the trial court. Of course, the yoke (8) is configured to be easily replaceable by being loaded on a recombination device and moved.

いる。FIG. 5 is a view taken along the line D-D in FIG. 2 (b), showing the relationship among the intermediate housing (3), WS outer housing +11, DS outer housing, and sole plate (4). The WS outer housing Tll and the intermediate housing 431 are fixed to the sole plate (4) with bolts as described above. That is, the intermediate housing (3) is a single rigid body in which the front and rear frames are joined at the upper and lower surfaces'. This lower joint frame part is fixed to the sole plate (4) with a foot bolt (20), and the WS outer/'% Uzing +11 is also attached to the foot bolt (20).
It is fixed to the sole plate (4) with a bolt (21).

Ｌ−Ｃ＠−Ｃお、ゆ。、い。In this way, the intermediate housing (3) and the WS outer housing 11 are fixed to the sole plate (4), and the DS outer housing (2) is shifted by the shift cylinder (16) in accordance with the roll span. Further, the yoke (8) portion of the intermediate housing (3) containing the pressure regulating device can be coated with a film. Therefore, since the horizontal roll reaction force and the vertical roll reaction force are absorbed within each housing, there is no need to provide a structure that ensures a reaction force absorption system without changing the roll span ratio. That is,
This is because the roll span can be changed without having to deal with areas subject to huge rolling reaction forces. Furthermore, the d-ru can be easily replaced by removing the yoke (8) of the WS outer housing (1). At the same time, by removing the seek (8) of the DS outer housing (2), it is possible to reduce the diameter of the horizontal roll for double rolling.・In this way, the present invention makes it possible to create an extremely rational universal and dual-purpose rolling mill, but the drive universal and spindle are also within reach, and a large-capacity cross-pin type splined uniparser, 't nt9a ear. .

は熱論である。Further, in this embodiment, the DS outer housing is shifted, but the same effect as above can be obtained even if the DS outer housing is fixed to the sole plate and the WS outer housing is shifted. It is a hot topic that the outer housing may be configured to be shiftable together.
