In the embodiment two feed rails are operated by the followers on a press, Fig. 1, for making can lids with tear-off strips from strip material, the feed rails carrying pockets into which the parts stamped out are ejected during descent of the press-tools 21-30. These are mounted on rams 9, 10, 35, 36 driven, through eccentrics and connecting rods, from a shaft 4 which also drives the drum cam 38 through gearings 39, 40. During ascent of the rams the blanks are lifted out by the pockets and moved against top tools mounted on a head plate 3. The rollers 43, 44 are mounted on a bolt 45 moved axially by a nut 46 to take up play and prevented by a key 49 from rotating. The rails 47 are guided by cylindrical and bevel rollers (52, 53), Fig. 3 (not shown), on eccentric bolts.

From the initial blank, a workpiece-pipe is obtained by the pre-machining process, that has at the ends a feed and a leading part. Workpiece-pipe is subjected to a radial reduction on the radial-crimping machine with fastening of its feed and the leading parts, respectively, in the retaining and hollow driving centers of the machine. Hollow driving center has a small cylinder with teeth at the end in the front, a large cylinder in the middle part, with grooves without back walls, and a shank in the rear. End of the small cylinder is tilted toward the big cylinder. Preliminary machine work is carried out to obtain at the end face of the cylinder a leading part of the preform-liner pipe separating the annular cavities from the axial hole of the preform-pipe. When fastening the leading part of the workpiece-pipe in the hollow lead center, the shank without a gap is placed in the cavity, which is performed on the end face of the small cylinder of the hollow driving center. EFFECT: reduction of transverse vibrations of the leading part of the workpiece-pipe during radial reduction is provided. 3 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 652 924 C1 (51) МПК B21K 21/06 (2006.01) B21J 13/08 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ На основании пункта 1 статьи 1366 части четвертой Гражданского кодекса Российской Федерации патентообладатель обязуется заключить договор об отчуждении патента на условиях, соответствующих установившейся практике, с любым гражданином Российской Федерации или российским юридическим лицом, кто первым изъявил такое желание и уведомил об этом патентообладателя и федеральный орган исполнительной власти по интеллектуальной собственности.

Conveying workpieces is by the system of series of work stations

一种用于输送工件通过一系列等间距，直线排列的工位的系统，在这些工位上按预定程序对工件进行加工。工件沿X轴的输送是借助工件吏爪操纵器，它以相应工位的间隔等间距设置安装在输送导轨上。输送导轨沿X轴往复运动的距离等于相邻工位间的间隔，独立支撑操作装置的横向臂支撑输送导轨使之上下前后运动。用于使工件在所有三个轴运动的装置是单独控制的且可与如带输送装置冲压机的操作相配合。

Supplying apparatus of materials to press

Material is fed to a high-speed press by an arrangement in which the carry-out arm for pressed material is in a higher plane than that in which the carry in arm for new material is turned. The arms move pivotally in a horizontal direction and linearly in a vertical direction. The fulcrum for pivoting is mounted on a rear surface of the press bolster. The dead point of the carry-in arm is at the end of in-feeding and that for the carry-out arm is at the start of out- feeding. Movements of the arms are timed so that the materials fed in and taken out are overlapped vertically in a position above a lower press die.

Methods for producing parts with dead or through openings by cold pressing and plant for performing the same

FIELD: plastic working of metals, possibly manufacture of metallic parts with given diameters. SUBSTANCE: method may be used for producing parts with diameter exceeding 30 mm. Method comprises steps of cutting blanks in the form of coils or rods by predetermined length pieces; subjecting cut pieces to progressive pressing by passing them through working units of plant. The last includes row of hydraulic presses. Worked blanks are transferred from one press to other press by respective automatic manipulators. If necessary, through opening is formed in blank due to removing cross portion dividing two dead openings formed at pressing. EFFECT: improved quality of parts, lowered metal consumption for making them. 26 cl, 5 dwg ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß (19) RU (11) 2 323 061 (13) C2 (51) ÌÏÊ B21K B21K B21K B21K B21J 21/00 (2006.01) 1/68 (2006.01) 1/46 (2006.01) 27/04 (2006.01) 9/02 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2004121678/02, 26.02.2003 (72) Àâòîð(û): ÂÅÑÊÎÂÈÍÈ Àëåññàíäðî (IT) (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 26.02.2003 (73) Ïàòåíòîîáëàäàòåëü(è): ÀÌÀÔÀ ÑÅÐÂÈÑ ÑÐË.

Method of piece loading of bars into technological equipment for treatment thereof and device therefor

Изобретения относятся к вспомогательному оборудованию, используемому при обработке прутков. Для поштучной загрузки прутков в технологическое оборудование для обработки их россыпью подают на раскатный стол в виде движущейся в направлении упомянутого оборудования транспортерной ленты. Прутки перемещают в один ряд посредством механизма перемещения, имеющего ролик с приводом вращения. При этом обеспечивают подачу прутков в пространстве между транспортерной лентой и роликом. Ролик посредством подъемно-винтовой системы устанавливают с зазором относительно транспортерной ленты, на 2-4 мм превышающим диаметр прутка. Ролик приводят во вращение в сторону, противоположную направлению движения транспортерной ленты, со скоростью, превышающей скорость движения транспортерной ленты. В результате обеспечивается возможность подачи для обработки прутков малого диаметра, хаотично загружаемых на раскатный стол. 2 н. и 1 з.п. ф-лы, 2 ил.
