TURRET ROLL FORMERS, FORMING ROLLER CASSETTES AND RELATED ARTICLES AND METHODS

A turret roll forming machine includes at least one turret assembly carrying multiple rows of tooling (e.g., forming rollers), rotatable about an axis to selectively align rows of tooling with an input or output. A transmission is accessible from an exterior of the turret assembly without disassembling of the turret assembly to perform a changeover of roll tooling and/or maintenance on gears, bearings, or shafts of the transmission. Thus, a chain drive may be employed, advantageously accommodating differing rotational speeds for top and bottom forming rollers of each pair of forming rollers, e.g. to reduce roll scuffing. Pairs of forming rollers may be provided as cassettes, which are removably coupleable to the turret assembly allowing quick and easy reconfiguration and/or servicing, minimizing negative effects of changeover. The turret assembly may be a unitary structure (e.g., a weldment) improving rigidity and increasing accuracy of roll forming operations. 1.

Прокатна клеть с многовалковым калибром

Rolling mill for making flat stock

Изобретение относитс  к прокатному производству и предназначено дл  прокатки листов и полос. Цель изобретени  - повышение точности прокатки путем расширени  пределов регулировани  профил  межвалкового зазора, снижение металлоемкости рабочей клети и повышение ее долговечности. Привод 8 на промежуточные валки 3 позвол ет на пор док изменить пределы регулировани  прогиба валка, взаимодействующего с рабочим, и за счет этого значительно расширить пределы регулировани  межвалкового зазора. При этом уменьшение диаметра валка 3, взаимодействующего с рабочим валком 2, позвол ет более эффективно воздействовать на профиль межвалкового зазора в св зи с тем, что при одном и том же прогибе рабочего валка в горизонтальной плоскости меньший диаметр промежуточного валка способствует более значительному увеличению межвалкового зазора по оси прокатки. 1 ил. The invention relates to rolling production and is intended for rolling sheets and strips. The purpose of the invention is to improve the rolling accuracy by expanding the limits of adjusting the roll gap, reducing the metal capacity of the working stand and increasing its durability. The drive 8 to the intermediate rolls 3 allows for an order of magnitude to change the limits of the adjustment of the roll deflection, interacting with the worker, and thereby significantly expand the limits of adjustment of the roll gap. At the same time, reducing the diameter of the roll 3, which interacts with the work roll 2, makes it possible to more effectively influence the profile of the roll gap due to the fact that with the same deflection of the work roll in the horizontal plane, a smaller diameter of the intermediate roll contributes to a more significant increase of the roll gap along the rolling axis. 1 il.

Continuous mandrel mill

FIELD: lengthwise rolling of tubes. SUBSTANCE: a rolling mill for elongation rolling of hollow products with use of a mandrel includes at least one main deforming stand with universal arrangement of rolls, provided by controllable rolls. A double-roll final rolling stand is mounted behind the main deforming stand. If it is necessary, a drive stand may be mounted before the main deforming stand. That allows to decrease at most a number of stands of the rolling mill without lowering of quality of products, being rolled. EFFECT: lowered number of stands of rolling mill. 1 cl, 2 dwg 95 6З3ЗУОбОс ПЧ Го РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (19) ВИ “” 2048 936 ' (51) МПК 13) СЛ В 21В 17/04, 13/12 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 5001476/02, 18.09.1991 (30) Приоритет: 19.09.1990 ОЕ Р 4030046.3 (46) Дата публикации: 27.11.1995 (56) Ссылки: Авторское свидетельство СССР М 295585, кл.
