Description
Technical field
The invention belongs to mechanical equipment technical field.
Background technique
Structural feature due to rotary squeezing machine needs complete machine to rotate, and hydraulic pipe line thus must be made to realize rotary transfer hydraulic oil, and simultaneously because equipment tonnage is high, hydraulic oil demand is large, needs pipeline latus rectum to do greatly as far as possible.Existing swivel joint latus rectum is little, and oil inlet and outlet can only coaxially be carried, and cannot meet this operating mode needs.
Summary of the invention
For realizing hydraulic pressure big orifice rotary transfer function, the present invention aims at rotating electrode extrusion press and designs following technological scheme: a kind of hydraulic pressure low pressure big orifice swivel joint, it is characterized in that: the latus rectum being provided with mutual vertical connection in spool, the diameter of this latus rectum can reach 250 ㎜.Spool front end is provided with radial oil outlet and middle part bilateral symmetry is provided with two oil inlet holes altogether.The section area of spool latus rectum is equal with the sum value of two oil inlet hole section area that bilateral symmetry in the middle part of spool is provided with.Valve body is provided with the oil pocket of band filler opening, and sliding sleeve i and sliding sleeve ii is located at the front end and back end of valve body respectively.Spool mid-rear portion is axially placed in valve body, and seal ring ii is placed between described valve body and spool outer peripheral surface, plug by end cap through screw fastening at valve body tail end, be provided with seal ring i between plug side and spool afterbody outer peripheral surface.The radial oil outlet that spool front end is provided with can be any angle according to erecting bed actual conditions and vertical direction.
The present invention of technique scheme is adopted to obtain following technique effect:
(1) technological scheme of the present invention makes swivel joint achieve the little and effect that latus rectum bore is large of volume, the maximum 250mm that reaches of latus rectum D, rated pressure 5MPa;
(2) the area summation quantity in area and spool two filler opening cross sections in valve core cavity cross section is equal, makes hydraulic oil enter spool smoothly and avoids producing damping and impact phenomenon;
(3) spool is anchored on the end face of rotary squeezing machine gudgeon, and oil outlet direction is vertical with extrusion press rotation centerline, realizes hydraulic pipe line and together rotates with rotary squeezing owner clutch release slave cylinder;
(4) fixed end filler opening can be designed to be the arbitrarily angled installation of 0-360 ° with vertical direction according to erecting bed actual conditions.For convenience of the installation of filler opening in this example, the angle that equipment pipe arrangement is taked is 90 °.

Embodiment
Below in conjunction with accompanying drawing and example, the present invention will be further described.
Spool 08 front end is fastened by bolts the side at rotary squeezing machine gudgeon 13, and oil outlet 12 direction is vertical with extrusion press rotation centerline, can realize hydraulic pipe line and together rotate with rotary squeezing owner clutch release slave cylinder.
Valve body 01 is fastened by bolts on fixed support 09, prevents valve body 01 from rotating.Be provided with the latus rectum 15 of mutual vertical connection in spool 08, the diameter of this latus rectum 15 can reach 250 ㎜, and rated pressure can reach 5Mpa.In spool 08, the area summation quantity in area and spool 08 two filler opening 11 cross sections in latus rectum 15 cross section is equal, makes hydraulic oil enter spool 08 smoothly and avoids producing damping and impact phenomenon.Rear portion and the valve body 01 of spool 08 are coaxially installed.Valve body 01 inner chamber is provided with seal ring i-05, prevents hydraulic fluid leak.Plug 04 is fixed on spool 08 rear end by bolt by end cap 03, and prevents hydraulic fluid leak by the sealing of seal ring ii-06.Sliding sleeve i-07 1 are placed between valve body 01 and spool 08, and another part sliding sleeve ii-02 is placed between valve body 01 and end cap 03, all adopts high-abrasive material, serves as sliding bearing, for the rotation demand of swivel joint.
In actual mechanical process, the filler opening 10 of hydraulic oil through valve body 01 side enters into the inner chamber 14 of valve body 01, and two spool oil inlet holes 11 then through being symmetrically distributed in spool 08 both sides enter into latus rectum 15 in spool, are finally flowed out by spool oil outlet 12.Because valve body 01 maintains static, filler opening 10 can be designed to be the arbitrarily angled installation in 0-360 ° with vertical direction according to erecting bed actual conditions.For convenience of the installation of filler opening in this example, the angle that equipment pipe arrangement is taked is 90 °.Spool 08 can rotate with equipment, and when rotary squeezing machine rotates, hydraulic oil can successfully flow into from valve body filler opening 10, and flows out from spool oil outlet 12 along with the rotation of equipment, and final supply rotary squeezing owner clutch release slave cylinder is oily, realizes the allomeric function of this equipment.
