(54) УСТРОЙСТВО ДЛЯ РОТАЦИОННОГО ВЫДАВЛИВАНИЯ(54) DEVICE FOR ROTARY EXTRACT

Изобретение относитс к области обработки металлов давлением, а именно к устройствам дл ротационного выдавливани .The invention relates to the field of metal forming, namely, devices for rotary extrusion.

Известно устройство дл ротационного выдавливани , содержащее установленные в корпусе между опорными конусами давильные элементы, а также оправку 1.A device for rotary extrusion is known, comprising pressure elements installed in the housing between the support cones, as well as a mandrel 1.

Недостатком известного устройства вл етс низкое качество изделий с толщиной стенки 0,2 мм и кольцевыми утолщени ми.A disadvantage of the known device is the low quality of products with a wall thickness of 0.2 mm and annular thickenings.

Целью изобретени вл етс повыщение качества обработки и расщирение технологических возможностей устройства путем обеспечени возможности обработки тонкостенных изделий с кольцевыми выступами.The aim of the invention is to improve the quality of processing and the expansion of the technological capabilities of the device by allowing the processing of thin-walled products with annular projections.

Эта цель достигаетс за счет того, что предлагаемое устройство снабжено смонтированными на корпусе перпендикул рно оси оправки кольцевыми опорами и размещенными в них по окружности параллельно оси оправки колонками, а также установленными на одной из кольцевых опор захватами , взаимодействующими с соответствующим опорным конусом, и смонтированными между опорными конусами и подпружиненными в осевом направлении прижимными конусами , установленными с возможностью вращени и взаимодействи с давильными роликами, при этом устройство снабжено смонтированным в корпусе перпендикул рно оси оправки сепаратором, а давильные элементы установлены в нем с возможностью радиального перемещени .This goal is achieved due to the fact that the proposed device is equipped with annular supports mounted on the housing perpendicular to the axis of the mandrel and columns arranged in them circumferentially parallel to the axis of the mandrel, as well as grippers mounted on one of the annular supports interacting with the corresponding support cone and mounted between support cones and axially spring-loaded pressure cones mounted for rotation and engagement with pressure rollers, while the device nabzheno mounted in the housing perpendicular to the axis of the mandrel separator and The squeezing elements installed therein with the possibility of radial movement.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 - сечение по А-А на фиг. 1.FIG. 1 shows the proposed device, a general view; in fig. 2 is a section along A-A in FIG. one.

Устройство содержит установленные в корпусе 1 давильные ролики 2, помещенные между опорными конусами 3, которые св заны между собой направл ющими штыр ми 4 и гайкой 5 через пружину 6.The device comprises pressure rollers 2 installed in housing 1, placed between support cones 3, which are interconnected by guide pins 4 and nut 5 through spring 6.

Ролики посто нно поджаты посредством пружин 7; расположенных на щпильках 8, прижимными конусами 9, которые свободно поворачиваютс относительно кольца 10.The rollers are constantly tightened by means of springs 7; located on the studs 8, pressure cones 9, which freely rotate relative to the ring 10.

Ролики установлены в сепараторе 11, состо щем из пластин с радиальными пазами , скрепленных распорками 12.The rollers are mounted in a separator 11, consisting of plates with radial grooves, fastened with spacers 12.

Claims

The grippers 13 are located on an annular support 14, which is mounted on a column x 15, freely sliding in the housing 1 mounted on a bracket 16 rigidly connected to a machine caliper (not shown). In this case, the other end is fixed on the annular support 17. The wedge 18, connected with the machine follower drive, is constantly pressed by the spring 19, with its working surface interacts with the annular support 17. The columns 20 serve to guide the wedge. To fix the rollers in a certain position A stop 21 is mounted on the housing. The blank 22 is mounted on the mandrel 23 with the help of the clamps 24. The device operates as follows. The blank 22 is put on the mandrel 23 and pressed by the clamp 24. The rollers 2 are in the upper position, which is provided by the clamping cones 9. When turning on the mandrel and the longitudinal slide of the caliper, the machine system moves the wedge 18, which is in a constantly depressed position under the action springs 19 and directed columns 20, embedded in the bracket 16, rigidly mounted on the longitudinal support of the machine. Under the action of the wedge, the annular support 17, through the columns 15, which pass through the openings of the housing 1, moves the support 14. The interrupted hooks 13 on it act on the supporting cones 3, one of which is housed in the housing. The support cones, which are interconnected by the guide pins 4 and the nut 5, through the spring 6, move the pressing rollers in the following mode along radial grooves, separator plates AND, to a certain position limited by the stop 21. The device allows rotating rotary pulling holders in the following mode on a press or lathe and obtain cylindrical and conical, with a small taper, parts with a particularly thin wall and annular outer thickenings and a difference in thickness from 0.2 mm to 10 mm in one piece. The pressure cones constantly press the rollers to the working surfaces of the support cones at the moment they are not in contact with the workpiece material, and the separator with the radial grooves increases the range of the radial movement of the rollers, eliminates the contact of the rollers with each other, which significantly reduces vibration, improves the roller cage durability and improves the quality the details. An invention of a device for rotational extrusion, comprising pressure rollers installed in a housing between support cones, as well as a mandrel, characterized in that, in order to improve the quality of processing and expand the technological capabilities of the device by enabling the processing of thin-walled products with annular projections, it is equipped with perpendicular to the axis of the mandrel by annular supports and columns arranged in them circumferentially parallel to the axis of the mandrel, and also mounted E on one of the circumferential bearing grippers interacting with respective support cone and mounted between the bearing cone and spring-loaded in the axial direction of clamping cones mounted rotatably and reacting with a juicer rollers.

2. The device according to claim 1, characterized in that it is provided with a separator mounted perpendicular to the axis of the mandrel in the housing, and the pressing rollers are installed therein with the possibility of radial movement.
