(54) РОЛИКОВАЯ ЮЛОКА(54) ROLLER YOLOK

Изобретение относитс к волочильному производству .FIELD: dragging.

Известна роликова волока, включающа установленные в корпусе с возможностью относительно своей осн, по меньшей мере , даа образующих калибр ролика с цапфами 1.A roller dredging is known, including those installed in the housing with the possibility of at least one of the axles of the roller with the trunnions 1 relative to its base.

Дл задачи передиего конца заготовки в известную волоку необходимо заострить его на охециапыюм оборудовании, при этом форма и размеры его будзт: отличатьс от формы и размеров получаемого издели и после волочени Ьтот конец отрезают.For the task of the front end of the workpiece, it is necessary to sharpen it into well-known fiber equipment, with the shape and size of its butst: differ from the shape and dimensions of the resulting product and after dragging this end is cut off.

Целью изобретени вл етс повышение выхода годного за счет обжати переднего конtta заготовки и волочени остальной части затотовки в одной волоке.The aim of the invention is to increase the yield by reducing the front contour of the workpiece and dragging the rest of the cutting into one drag.

Эта цель достигаетс тем, что, по меньшей мере, один из роликов снабжен приводом вращени и средством дл отключени привода от ролика после задачи заготовки. Привод враше ш и средство дл отключени привода выполнены в виде зубчатой шестерни, посаженной на цапфу ролика, вход щей в зацепление с зубчатой рейкой, соединенной со штоком гидроци;1шадра .This goal is achieved in that at least one of the rollers is provided with a rotational drive and means for disconnecting the drive from the roller after the workpiece task. The drive is raised and the means for disabling the drive are made in the form of a gear gear, seated on a roller journal that engages with a gear rack connected to the rod of the hydrocyon; 1shadr.

На фиг. 1 изображена двухроликова войока , продольный разрез; на фнг. 2 - разрез А-А на фиг.1.FIG. 1 shows a two-roll roll, longitudinal section; on fng. 2 shows a section A-A in FIG.

Устройство включает установленный на стаН1ше 1 корпус 2, в котором ролики 3 и 4 с цапфами 5-8 установлены в подшипниковых опорах 9-12, причем цапфа 8 ролика 4 вьпюлнена удлиненной и на нее на шпонке 13 посажена зубчата шестерн 14, вход ща в зацепление с зубчатой рейкой 15, установленной в направл ющих 16 станины 1 И соединенной со штоком 17 гидроцшшндра 18.The device includes a housing 2 mounted on a stancion 1, in which rollers 3 and 4 with pins 5–8 are installed in bearing supports 9–12, and pins 8 of roller 4 are elongated and gear cog 14 is seated on it 13 and is engaged. with a toothed rack 15 installed in the guides 16 of the bed 1 and connected to the rod 17 of the hydraulic dial 18.

Claims

Roller portage works as follows. Before dragging the rack and pinion, the rail 15 is in the extreme right position and engages with the gear gear 14. The workpiece is fed along the axis of the drag to the rollers 3 and 4. The working fluid under pressure enters the hydraulic cylinder; moves to the left, the gear gear 14 rotates and the roller 4 rotates. The end of the workpiece is tightened for a length sufficient to grip the end of the workpiece with a mill stator (not shown in the drawings). Then the rack bar 15, moving to the left, disengages from the gear 14 and the rotational drive of the roller 4 is turned off. Further, the device draws the workpiece. By the end of the dragging of the cylinder cylinder 18, the gear rack 15 and the gear gear 14 are returned to the starting position, and the cycle is repeated. Claim 1. Roller portage, including the installation of a netntbie in the housing with the possibility of rotation around its axis, at least two forming a caliber of roller with pins, I distinguish

In addition, in order to turn out the yield by crimping the front end of the workpiece and drawing the rest of the workpiece in one drag, at least one of the rollers is provided with a rotary drive and means for disconnecting the drive from the roller after the task of the blank.

2. Voloka according to Claim 1, characterized in that the rotational drive and the means for deactivating the drive are made in the form of a gear gear, seated on a roller journal, which engages with a rack gear connected to the hydraulic cylinder rod.
