Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, this high-speed blanking press bulb ball bowl lubrication oil circulation lubrication structure, including slide block cylinder body 3, hydraulic cushion cylinder 5, guide pillar screw rod 8, lower adjusting nut 9, upper adjusting nut 11, slide block gland 12, worm gear gear ring 17 and worm gear case 18, upper adjusting nut 11 connects removable pin 10 by two and forms a whole with lower adjusting nut 9, and be connected with the bottom of guide pillar screw rod 8 by screw thread, upper adjusting nut 11 and lower adjusting nut 9 fit in the slide block cylinder body 3 being welded on press ram 30;Being provided with hydraulic cushion cylinder 5 bottom slide block cylinder body 3, be provided with hydraulic die cushion port connection 4, be provided with hydraulic die cushion piston 7 between hydraulic cushion cylinder 5 and lower adjusting nut 9 bottom hydraulic cushion cylinder 5, the top of slide block cylinder body 3 is connected with slide block gland 12;The top of guide pillar screw rod 8 offers guide pillar screw rod circular hole, ball head connecting rod 14 is put in guide pillar screw rod circular hole by sphere-contact by upper ball bowl 16 and lower ball bowl 21, union (screwed)bonnet (UB 15 is positioned at ball bowl 16 top position and is connected with guide pillar screw rod 8 by the female thread of guide pillar screw rod circular hole, thus upper ball bowl 16 is carried out axial limiting;Guide pillar screw rod 8 top is connected with worm gear gear ring 17 by outside spline tooth, worm gear case 18 is fixed on press crown 28, also include Lubricating pump station 1, Lubricating pump station 1 is arranged on forcing press sill 29 side, lubricating oil oil-in 6 is opened on the sidewall of slide block cylinder body 3, Lubricating pump station 1 is connected with lubricating oil oil-in 6 by oil inlet pipe 2 and implements fuel feeding, Lubricating pump station 1 is connected with the grease chamber in press crown 28 by oil return pipe 13 and implements oil return, guide pillar screw rod 8 is internal offers a through oilhole 20, lower ball bowl 21 bottom centre position offers oil-in 26, through oilhole 20 and oil-in 26 communicate, piston gap 19 is offered on hydraulic die cushion piston 7 sidewall, piston gap 19 respectively with the through oilhole 20 of guide pillar screw rod 8, lubricating oil oil-in 6 communicates.
The mode of lubrication oil circulation lubrication of the present invention is:
The entrance channel of lubricating oil: lubricating oil self-lubricating pumping plant 1 is along oil inlet pipe 2, after lubricating oil oil-in 6 enters slide block cylinder body 3, the piston gap 19 along hydraulic die cushion piston 7 side enters piston cavity;When lubricating oil constantly enter, piston cavity oil pressure reach certain numerical value time, lubricating oil rises along the through oilhole 20 of guide pillar screw rod 8, subsequently enters the oil-in 26 of lower ball bowl 21.
The feed lubrication of lower ball bowl: after lubricating oil enters the oil-in 26 of lower ball bowl 21, bulb ball bowl from oil-in 26 out, is lubricated by lubricating oil along lower ball bowl 21 sphere.
The export channel of lubricating oil: flow continually out the lubricating oil of lower ball bowl 21, in the small space that upper and lower ball bowl-type becomes, oil level constantly rises, after oil pressure reaches certain numerical value, lubricating oil, from upper ball bowl 16 and the Spherical Clearance of ball head connecting rod 14, is back to the grease chamber in press crown 28;The lubricant level of grease chamber reach a certain height value time, will flow back in Lubricating pump station 1 along oil return pipe 13, thus realize lubricating oil circulation lubrication.
Circulation lubrication: the lubricating oil that Lubricating pump station 1 will reflux from oil return pipe 13, first filters, then into fuel tank;The built-in cooler of Lubricating pump station 1, the lubricating oil extracted out from fuel tank enters cooler, when oil temperature is dropped to the standard value given, continues fuel feeding along oil inlet pipe 2, thus realizes circulating the purpose of lubrication.
The supplying lubricant formula of the present invention and supply route are all changed all of a sudden, lubricating oil rely on pressure feed and non-gravity supply, lubricating oil supplies rather than from below to up from upper and upper supply, lubricating oil enters the inside of guide pillar screw rod 8 from through oilhole 20, the contact surface the most finally entered between bulb ball bowl is lubricated cooling to bulb ball bowl, last lubricating oil is back to the grease chamber in press crown 28, in oil return pipe 13 flows back into Lubricating pump station 1, completing a circulation, lubricating oil can also be cooled down by cooler in Lubricating pump station 1.
nullAs a further improvement on the present invention,As shown in Figure 3 and Figure 4,Multiple annular oil groove 27 is offered on lower ball bowl 21 sphere,Multiple annular oil groove 27 is in concentric structure,The center of circle of annular oil groove 27 overlaps with the center of circle of oil-in 26,By multiple radial slot 25 UNICOMs between adjacent two annular oil grooves 27,The most inboard annular oil groove 27 near oil-in 26 is connected with oil-in 26 by radial slot 25,Level off in bulb ball bowl contact surface gap under conditions of zero,Lubricating oil is entered by oil-in 26,Annular oil groove 27 is flowed to then along radial slot 25,Lubricating oil flows into the annular oil groove 27 of upper level the most step by step,The lower ball bowl 21 of final outflow,In order to make lubricating oil supply more uniform,Radial slot 25 between adjacent two annular oil grooves 27 can offer rational quantity as required.Use the manner that lubricating oil supply can be allowed more uniform, can be it is preferred that use.
In order to further make lubricating oil supply uniformly, the radial slot 25 between two adjacent annular oil grooves 27 is evenly arranged to be offered.
So that the pressure of lubricating oil of the present invention is capable of supplying from lower to upper, improve sealing effectiveness, the lower surface of slide block gland 12 arranges slide block gland end-face seal ring 22, medial surface at slide block gland 12 arranges slide block gland endoporus sealing ring 23, and the lateral surface at hydraulic cushion cylinder 5 arranges hydraulic cushion cylinder cylindrical sealing ring 24.
