Изобретение относитс к обработке м&таллов цавлением, в частности к устройств вам дл деформировани заготовок путемобкатки качающимс инструментом.The invention relates to the processing of metals by pressure, in particular to devices for you to deform workpieces by rolling with a swinging tool.

Известно устройство цл обкатки, содержащее корпус, размещенные в нем узел кр& плени заготовки, шаровую опору, кнструментодержатель установленный в шаровой опоре и соединенный посредством эксцентрика с зубчатым приводом кругового кй нательного движени ij. It is known a running-in device, comprising a housing, a knot located therein, & work piece, ball bearing, tool holder mounted in a ball bearing and connected through an eccentric with a gear drive of circular body movement ij.

Недостатками известного устройства вл ютс ступенчата и трудоемка регулировка угла качани инструмента путем смены эксцентриковых втулок, в также н&1эозможность изменени угла качани в про цессе деформировани ,; что необходимо дл интенсификации процесса.The disadvantages of the known device are the step and time-consuming adjustment of the tool swing angle by changing the eccentric bushings, and also the possibility of changing the swing angle during the deformation process; what is needed to intensify the process.

Цель изобретени - улучшение условий эксплуатации путем облегчени перенала ки устройства.The purpose of the invention is to improve the operating conditions by facilitating the transfer of the device.

С этой цепью устройство снабжено м& ханиэмом осевого перемещени эксцентрика , а такжб сменной профильной втулкой.With this chain, the device is equipped with a m & hanem of axial movement of the eccentric, as well as a replaceable profile sleeve.

Устройство состоит из корпуса 1, в ко-тором размещена шарова опора 2 с установленным в ней анструментодержателем 3 с ийструментом 4. Сверху инструментодержатель поджимаетс крышкой 5, служащей направл ющей втулкой дл заготовкиThe device consists of a body 1, in which the ball bearing 2 with an instrument holder 3 with a tool 4 installed therein is placed. The tool holder is pressed against the lid 5, which serves as a bushing for the workpiece.

В нижней части корпуса 1 находитс эксцентриковый мехакизм, .вклшчающий подшипники 8, воспринимающие как осевую, так и рапиалЫHjro нагрузку, эксцентрик 9, соединенный посредством шпонки 10 с зубчатым приводом в внпе шестерни 11 н колеса 12,7, pushing the workpiece. In the lower part of the housing 1 there is an eccentric mechakizm, engaging the bearings 8, perceiving both axial and rapial load, the eccentric 9 connected by means of a key 10 with a gear drive in the gear 11 11 of the wheel 12,

Claims

In the upper part of the eccentric on the spike 13, the axis of which is displaced by the magnitude of the axial rotation of the eccentric relative to the axis, the eccentric is set, the roller 14. The axial movement of the axle 11 is made in the form of a roller 15 mounted in a binder 16 and interacting with the drive copy 17. By means of a key 18, it is connected to the housing 1. An elastic sleeve 19 is installed between the housing 1 and the instrument holder. A replaceable profile sleeve 20 is installed on the inner surface of the shank of the tool holder 3. All the mouth, the space can t be fixed to the rotor Korpu ce / tannin 21. The apparatus operates as follows. 1 azhatelnoe movement cogwheel ca 12 is transmitted through the gear 11, the eccentric 9 At this point, the tool holder swingable s an angle of zero, i.e. the axis of the tool 4 coincides with the axis of the workpiece 6. In this position, the tool holder is held by the elastic sleeve 19 mounted on it. Through the pad 16 and the rollers 15, the eccentric 9 starts axial displacement of the eccentric 9. When the roller 14 of the moving eccentric reaches the inner surface of the tool holder ( an eccentric trick can also be performed (covering the shank of the tool holder), a rotating-thermal movement of the eccentric. 9 is transformed in the circular movement of the tool 4. Moreover, when moving by the copier 17 of the eccentric 9 of the upper, the swing angle increases, and when the eccentric is swept down, the swing angle decreases. In the lowest position of the eccentric tool holder again occupies the zero position. Thus, the movement of the round running is reported to the tool periodically. This technical solution ensures the durability of the device, since the movement of the circular running around communicates with the tool periodically, only during the period of deformation of the workpiece. In addition, the elastic sleeve, mounted on the tool holder, ensures that the tools 1 hold the tool firmly against the rotating eccentric, which increases the reliability of the device. A change in the swing angle during the deformation process makes it possible to intensify the metal flow. Equipping the tool holder with a replaceable profile sleeve allows you to set any desired law of change of the swing angle during the process and obtain parts of various configurations without changing wedges and a copier, which serve for a given movement of the eccentric. . The invention of the device for running in, comprising a housing, a hub, a ball bearing, a tool holder mounted in a ball bearing and connected through an eccentric with a gear drive of a circular oscillating motor, characterized in that with the aim of improving the CONDITIONS of operation by facilitating changeover, it is equipped with a mechanism for the axial movement of the eccentric, as well as a replaceable profile sleeve, located between the eccentric and the tool holder -.
