As shown in fig. 1, 2 and 3, the forging operation oil electric joint device provided by the invention comprises a rotary joint device 10 and an electrically conductive slip ring device 20.
The rotary joint device 10 includes a rotary body 11 and a joint sleeve 12 fitted over the rotary body.
The revolving body 11 includes an upper section and a lower section; five oil inlets 11-1 are formed in the upper surface of the upper section and correspond to a cart walking inlet, a cart oil return opening, a cart rotating inlet, a cart oil return opening and a total oil return opening respectively; the five oil inlets are circumferentially equidistant along the circle center. In this embodiment, five oil inlets are located on a semicircular surface, and one oil inlet is disposed at an angle of 45 degrees.
The upper surface of the upper section is also provided with two fixing holes 11-3, wherein one fixing hole passes through the center of a circle; the other is opposite to the five oil inlets 11-1. One end of the hard rod is fixed on the trolley frame, and the other end of the hard rod is fixed on the revolving body through two fixing holes 11-3, and when the trolley frame rotates, the revolving body also rotates along with the trolley frame.
Annular grooves 11-4 with the same number as the oil inlet holes are longitudinally arranged at the lower section of the revolving body; the oil inlet 11-1 communicates with the annular groove 11-4 through an internal oil passage.
The joint sleeve 12 is sleeved on the lower section of the revolving body 11, an oil outlet hole 15 communicated with the annular groove 11-4 is longitudinally arranged on the side wall of the joint sleeve 12, and an oil outlet joint is arranged at the oil outlet hole. The five oil outlet joints are sequentially communicated with the cart travelling car pipe, the cart oil return car pipe, the cart rotating car pipe, the cart oil return car pipe and the main oil return pipe from top to bottom.
An upper guide ring 13 is arranged at the upper end of the joint sleeve 12, and a lower guide ring 17 is arranged at the lower end; the upper guide ring 13 is fixed at the upper end of the joint sleeve 12 through a stabilizing flange 14; the lower guide ring 17 is fixed at the lower end of the joint sleeve 12 through the base 16; two guide rings 13, 17 fix the rotator 11 in the joint cover 12. The base 16 is in threaded connection with the joint sleeve 12; the stabilizing flange 14 and the joint sleeve 12 are fixedly connected by bolts. The base 16 is fixed on the chassis of the cart by bolts, and the joint sleeve 12 which is in threaded connection with the base is also in a fixed state.
