Abstract

PURPOSE:To enable the recombination of a roll with a simple spindle holding device by providing the inner housing to store a roll chock inside the housing of an universal rolling mill and providing a height adjusting means and holding means between the inner housing and sled. CONSTITUTION:The heights of a vertical roll chock 4 and horizontal chocks 5, 6 are adjusted via a sled 2 and cartridge 3 by changing the thickness of a liner 12 at rolling time and the position at the height of each roll 7, 8, 9 is set to the center in the thickness of a rolling material. At the roll recombination time a rail 13 is ascended and the heights of the sled 2, chock 6, chock 4 and chock 5 are held constantly at all times via spacer rods 14, 15, 16. The alignment of the center in the thickness of the rolling material and the center of a roll 7, and the alignment of the shaft center of the rolls 8, 9 to the center of spindles 10, 11 becomes possible, the need to move the spindle holding device is eliminated and the structure is made simple.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は多品種の圧延製品を圧延できるユニバーサル圧

けた圧延機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a universal rolling mill capable of rolling a wide variety of rolled products, and particularly to a rolling mill provided with a cartridge inner housing.

〔従来の技術〕[Conventional technology]

側ハウジング内に上下水平ロール及び左右垂直ロールを
それぞれのチョックを介して組み込み、多品種のロール
幅のＨ形調圧延を水平、垂直両方同時に行なえるように
したユニバーサル圧延機が知られている。The rolling machine for H-shaped steel rolling equipment incorporates upper and lower horizontal rolls and left and right vertical rolls into the operation and drive side housings through their respective chocks, and can perform H-shaped rolling with a wide variety of roll widths both horizontally and vertically. A universal rolling mill that can perform simultaneous rolling is known.

圧延機前後に設置してテーブル上を移動通過する圧延材
の高さ方向の中心が、常に固定配置された垂直ロールの
中心に一致するようにしていた。This universal rolling mill has conventionally been equipped with vertical roll chocks fixed to a housing in the vertical direction. For this reason, it is not possible to adjust the height of the vertical rolls according to the dimensions of the product to be rolled, so tables that can move up and down are installed at the front and rear of the rolling mill, and the center of the height of the rolled material that moves over the table. but always aligned with the center of a fixedly placed vertical roll.

この方法によると上下可動式テーブルを圧延機の前後に
配置しなければならず設備費が高くなシ。According to this method, vertically movable tables must be placed before and after the rolling mill, resulting in high equipment costs.

しかも可動部が多いことから保守上にも問題があった。Moreover, since there were many moving parts, there were also problems in terms of maintenance.

この問題を解決するため特公昭４６−１０６５４号公報

されている。In order to solve this problem, as disclosed in Japanese Patent Publication No. 46-10654, an inner housing is provided in the form of a cartridge in the nozzle of a rolling mill, and this cartridge supports horizontal and vertical roll chocks. There have been proposals to adjust the height by moving it up and down.

In other words, when the height of the cartridge is changed, the height of the vertical roll chock also changes, and as a result, the height of the upper horizontal roll chock placed on the vertical roll chock changes. When taking out the cartridge, a mechanism is required to change the holding device of the spindle that drives the horizontal roll provided on the drive side according to changes in the height of the cartridge.

設備費が高くなるという問題があった。またスピンドル
保持装置が複雑となり保守上も不利となる欠点もあった
。There was a problem that equipment costs were high. Furthermore, the spindle holding device is complicated, which is disadvantageous in terms of maintenance.
