Изобретение относитс к областиобработки металлов давлением и может быть использовано при йзго-i товлении крутоизогнутых отводов методом прот жки труб. 5The invention relates to the field of metal processing by pressure and can be used for manufacturing curved bends by the method of drawing pipes. five
Известен гидравлический пресс дл изготовлени крутоизогнутых отводов 1, содержащий штангу с рогообразным сердечником и смазочное устройство, которое наносит смаз- О ку перед прот гиванием заготовки на штангу.A hydraulic press is known for making bent bends 1 containing a rod with a horn-like core and a lubricating device that lubricates before pulling the workpiece onto the rod.
Недостатком этого устройства в л етс то, что в период прохождени , заготовки по штанге больша часть 15 смазки тер етс , до начала прот жки.The disadvantage of this device is that during the passage of the workpiece on the rod a large part 15 of the lubricant is lost, before the start of drawing.
Известны также прессы, в которых смазка наноситс во врем прот жки труб 2. В этом случае в штанге выполнено отверстие в продоль- 20 ном направлении, а в месте соединени штанги с рогообразным сердечником выполнены радиальные отверсти .Presses are also known in which lubricant is applied during drawing pipes 2. In this case, a hole is made in the rod in the longitudinal direction, and radial holes are made at the junction of the rod with the horn-like core.
Недостатком такого устройства вл етс забивание отверстий и, 5 вследствие этого, ухудшение качества смазки.The disadvantage of such a device is clogging of the holes and, 5 as a result, deterioration of the lubricant quality.
В предложенном прессе эти недостатки устранены за счет того, что смазочное устройство выполнено в виде. iOIn the proposed press, these disadvantages are eliminated due to the fact that the lubricating device is made in the form. iO
упругой обоймы с косыми прорез ми,охватывающей штангу и закрепленной на ней одним концом, а дл применени жидкой смазки устройство снабжено пористой вставкой, установленной в полости между упругой обоймой и штангой.elastic cage with oblique cuts, covering the rod and fixed to it at one end, and for applying a liquid lubricant, the device is equipped with a porous insert installed in the cavity between the elastic casing and the rod.
На фиг.1 изображен гидравлический пресс, общий вид; на фиг.2 то же, после подачи заготовки; на фиг. 3 - смазочное устройство.Figure 1 shows a hydraulic press, a general view; figure 2 is the same, after the filing of the workpiece; in fig. 3 - lubricating device.
