Description

II

Изобретение относитс  к обработке металлов давлением, в частности к изгофовлению гнутых профилей путем формообразовани  в валках.The invention relates to the processing of metals by pressure, in particular to the tofiling of curved profiles by forming into rolls.

Известен способ изготовлени  профилей , преимущественно шевеллерообразных , при котором формоизменение осуществл ют по переходам путем равных горизонтальных смешений кромки заготовки в формующих валках при переходе от предыдущей клети к последующей l Этим способом можно получать профили больщой длины, орнако при изменении размеров профил  необходимо изготавливать вновь все валки.There is a known method of making profiles, mostly shevelleriform, in which the shaping is carried out at transitions by equal horizontal mixing of the workpiece edge in the forming rolls when going from the previous stand to the next one. This method can be used to produce profiles of a large length; .

Освоение профил  с новыми размерами требует больших затрат на изготовление оснастки, кроме Того, требуютс  большие площади и дорогосто щее оборудование .Mastering a profile with new dimensions requires a lot of cost for tooling, besides Togo, large areas and expensive equipment are required.

Цель изобретени  - снижение трудоемкости изготовлени  оснастки и уменьщение производственных площадей.The purpose of the invention is to reduce the labor intensity of making tooling and reducing production space.

По предлагаемому способу подгибку полок производ т стесненным изгибомAccording to the proposed method, bending of the shelves is carried out by constrained bending.

yм  парами валков, в первой из которых формуют профиль с отношениемin pairs of rolls, in the first of which a profile is molded with a ratio

Ъ,B,

5 и5 and

где - внутренний радиус гибки;where - the internal radius are flexible;

So - исходна  толщина материала;So is the initial material thickness;

Jl - пр молинейна  часть полки, а во второй паре получают окончательный размер профил  путем сжати  торцов заготовки .Jl is the straight part of the shelf, and in the second pair the final profile size is obtained by compressing the ends of the workpiece.

На фиг. I изображен щвеллерообразный профиль в процессе изготовлени ; на фиг. 2 - сечение по А-А на фиг. 1; на фиг. 3 - сечение по Б-Б на фиг. 1; на фиг. 4 - профиль, формуемый в первой паре валков.FIG. I shows the iron-shaped profile during the manufacturing process; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one; in fig. 4 - profile, molded in the first pair of rolls.

Перва  пара валков профилирует лист со значительной величиной относительного радиуса и небольшой высотой пр молинейных участков полок профил , а втора  пара валков осуществл ет поджатие торцов заготовки, при этом заготовка получает окончательный размер профил .The first pair of rolls profiles the sheet with a significant amount of relative radius and a small height of the straight sections of the profile shelves, and the second pair of rolls preloads the ends of the blank, and the blank receives the final size of the profile.
