Abstract

PURPOSE:To stably obtain products having a specified size even if rolls are worn by providing moving means for sliding roll shafts and hydraulic chambers for preventing the clatter of the roll shafts to the shaft end parts of the roll shafts to be fitted to sleeve rolls. CONSTITUTION:A nut 11 is turned through a reduction gear 14 and a connecting shaft 13 by operating a hydraulic motor 15 in order to expand the upper horizontal roll 4a to the roll width such as the width of the lower horizontal roll 4b. A screw rod 10 rotates and the roll shaft 6 connected thereto moves axially while sliding in the through-hole H and bearing 7 of the sleeve roll 5b. The roll width of the driving side roll LR, operation side roll RR fixed and held to the sleeve rolls 5a and 5b is changed in the expanding direction like the roll 4a. An oil pressure supply/discharge circuit in the hydraulic chamber 20 is set in an open state to avoid the exertion of the oil pressure and to supply the oil in a manner as to prevent the roll shaft 6 from clattering in the axial direction at the point of the time when the setting of the roll width is completed. The oil pressure is thus set to the prescribed pressure.

。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a rolling roll that can be used as a horizontal roll in a universal rolling mill used in the production of H-section steel, etc., and whose roll width can be suitably changed. It is something.

（従来の技術） Ｈ形鋼の圧延には上下一対の水平ロールと、左右一対の
垂直ロールを同一スタンドに組込んだユニバーサル圧延
機を使用するのが一般的である。(Prior Art) For rolling H-section steel, it is common to use a universal rolling mill that incorporates a pair of upper and lower horizontal rolls and a pair of left and right vertical rolls in the same stand.

（ｈ）はｈ＝Ｗ＋２ｔ、すなわちフランジ厚み（１１）
と水平ロールのロール幅（Ｗ）とによって決定されるた
め次のような問題があった。Conventionally, when manufacturing H-section steel using such a rolling mill, the flange width of the H-section steel can be changed freely as long as it is within the roll width of the vertical rolls, but the height of the web of the H-section steel ( h) is h=W+2t, i.e. flange thickness (11)
and the roll width (W) of the horizontal roll, which caused the following problems.

ス内においても圧延量の増加に伴いウェブ高さの不足を
きたし一定のサイズになる製品を安定して得ることがで
きず、これを回避するためにはロールの頻繁な取替を必
要とした。1) Since the inner surface of the flange is pressed and rolled with the end face of the horizontal roll, there is severe wear on the end face of the roll, and even within the same rolling chance, as the amount of rolling increases, the web height becomes insufficient, making it difficult to stabilize the product to a constant size. In order to avoid this, frequent replacement of the rolls was required.

２）　フランジ幅は自由に選択できるのに対しウェブ高

ともに工数がかさむ。3) In the case of h=W+2t for H-beam steel, the so-called constant outer rectangle H-beam steel with a constant web height H has many types of flange thickness (0+) even with the same designation size, so the roll width (W) of the horizontal roll It is necessary to change as appropriate depending on the required flange thickness (tl), but in order to accommodate this, frequent replacement of the rolls is required, which impedes productivity and increases the number of man-hours.

る費用が膨大となる不利があった。(Problems to be Solved by the Invention) However, in the method of inserting a spacer between the sleeve rolls, the horizontal rolls must be removed from the stand off-line, which impedes production efficiency and increases the number of assembly and disassembly steps. There are problems such as difficulty in finely adjusting the roll width, and methods that move sleeve rolls require a complicated structure to drive them, and the lateral rigidity of the rolls is low. When a rolling load is applied, the horizontal rolls wobble in the axial direction, resulting in problems such as poor dimensional accuracy of the product. Further, when using skew rolls, there is a disadvantage that the structure of the equipment is complicated and the cost involved is enormous.

大する方向へと変更される。Among the horizontal rolls shown in Figure 1 above, the upper horizontal roll 4
a is in a state where the roll width is reduced, and the lower horizontal roll 4h is in a state where the roll width is expanded, but now, in order to expand the roll width of the lower horizontal roll 4a to the lower horizontal roll 4b, first, The hydraulic motor 15 is operated, the reducer 14,
The nut 11 is rotated through the connecting shaft 13. The operation of this nut 11 causes the screw rod 10 to rotate, and the roll shaft 6 connected thereto to move along the axial direction while sliding in the through hole H' of the sleeve roll 5b and the bearing 7, so that the sleeve roll The roll widths of the drive-side roll Lll and the operation-side roll R fixedly held on the sleeve roll 5a and the sleeve roll 5b are changed in the direction of expansion like the lower horizontal roll 4a.

幅の設定が完了した時点でロール軸６が軸方向にがたつ
かないように油を供給して所定の圧力に設定する。At this time, the pressure oil supply and discharge circuit in the hydraulic chamber 20 is set to an open state so that no hydraulic pressure is applied to prevent the roll shaft 6 from shaking in the axial direction when the roll width setting is completed. Supply oil and set to the specified pressure.

性歪（εＸ）は−。When oil is supplied to bring the hydraulic chamber 20 to a predetermined pressure, an elastic strain corresponding to the load acting on the hydraulic chamber 20 is generated, and the roll width is reduced by an amount corresponding to this strain. Therefore, when setting the roll width, it is necessary to set the roll width to be thicker accordingly. Specifically, the above elastic strain (εX) is -.
