Abstract
The utility model discloses a hydraulic rotary feeder, which is composed of an oil pump fixed in a rotary feeding tank body, an oil motor, a one-way valve, an overflow valve, an oil strainer and a lubricator. The hydraulic rotary feeder adopts that a valve core and a valve body with oil holes are connected into a rotary distributing valve feeder whose transfer power is large and whose rotation is stable, accurate and reliable. The utility model can realize large range stepless regulation, high universality, high regulation precision and simple structure.
Description
Technical field
The utility model relates to a kind of rolling non-ferrous metal steel pipe process equipment, is mainly used in pipe revolution and feeder that cold pilger mill is used to control tube rolling.
Background technology
At present, the domestic existing mechanism of known hydraulic gyration feed mechanism, the mechanism of valve piece distributing valve associated working control oil motor intermittent movement with cam, fork, the intermittent movement of direction valve associated working control oil motor.But because of cam as dynamical element, efficient is low, a little less than the bearing capacity.Impact resistance is poor, and oil motor when work oil inlet quantity is unequal with recirculating oil quantity, can not form reliable back pressure, and is inhomogeneous when revolution is sent, actuation time instability, the revolution amount is adjusted difficult.When the higher revolution amount of head reciprocal time adjustment difficulty especially, and valve block structure complexity, assembly difficulty height.
In order to overcome the technical deficiency of existing hydraulic revolving feed device, the utility model provides a kind of hydraulic revolving feed device, this hydraulic revolving feed device adopts a valve body by spool and band oilhole to connect into rotatable distributing valve feeder, its transmitted power is big, running is stable, accurately and reliably, can realize that the step-less adjustment scope is big, highly versatile, degree of regulation height.
It is that casing (17) is sent in revolution to, interior oil pump (1), oil motor (6), check valve (11,12), overflow valve (5), oil filter (4), lubricating arrangement formed by being fixed on hydraulic revolving feed device that the utility model solves technical scheme that its technical problem adopts.And the control and regulation device is installed on the casing (21), connects into rotatable distributing valve (8) by a spool and a valve body being with oilhole.Oil pump one oil drain out connects through check valve (2), pressure meter switch (3), and distributing valve is connected with adjuster (9,10) and is connected with the oil return pipe that leads to fuel tank by check valve (11,12).
The beneficial effects of the utility model are that oil motor is sent the rotating accuracy height to, make the pipe diameter external diameter reach high accuracy, simple in structure, and are easy to use.

Fig. 2 is a structure chart of the present utility model;
Fig. 3 is a structure chart of the present utility model;
Fig. 4 is a rotatable distributing valve schematic diagram of the present utility model;
(1) double-united oil pump in the drawings; (2) check valve; (3) pressure meter switch; (4) oil filter; (5) overflow valve; (6,7) oil motor; (8) rotatable distributing valve; (9,10), adjuster; (11,12) check valve; (13) rotary output shaft; (14,16) send output shaft to; (15) electromagnetic clutch; (17) casing is sent in revolution to; (18) connect boss rod; (19) axle; (20) shaft coupling; (21) casing; (22) spool.
Concrete embodiment
In the drawings, distributing valve (8) is rotatable, and spool (22) is cylindric, there is cylindric oilhole distributing valve (8) valve body top, and wherein six oilholes are divided into two groups, and one group is the control feeder, another group has screw thread for the control slewing equipment on the oilhole limit, every group be into and out of, outage composition.By connecting the gear on the gear band moving axis (19) on the boss rod (18), drive shaft coupling (20) again and come rotational valve core, oilhole on the adjuster (9,10) and distributing valve (8) are connected into the governor motion of whole intermittent movement with oil connection.
Claims (3)
1, a kind of hydraulic revolving feed device is formed by being fixed on revolution oil pump, oil motor, check valve, overflow valve, oil filter, the lubricating arrangement sent in the casing; Its feature also is to control to adjust device and is installed on the casing, a valve body by spool and band oilhole connects into rotatable distributing valve, oil pump one oil drain out connects through check valve, pressure meter switch, again through overflow valve, rotary motor oil after distributing valve connect, distributing valve is connected with adjuster, and is connected with the oil return pipe that leads to fuel tank by check valve.
2, according to the described hydraulic revolving feed device of claim 1, its feature is that also distributing valve is rotatable, spool is cylindric, there is cylindric oilhole distributing valve valve body top, wherein six oilholes are divided into two groups, and one group is the control feeder, and another group is the control slewing equipment, oilhole has screw thread on the limit, and every group is to form into and out of, outage.
3, according to the described hydraulic revolving feed device of claim 1, its feature also is to connect the gear on the gear band moving axis on the boss rod, drive shaft coupling again and come rotational valve core, oilhole on the adjuster and distributing valve are connected into the governor motion of whole intermittent movement with oil connection.
