Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, this high-speed blanking press bulb ball bowl lubrication oil circulation lubrication structure, comprise 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 loose 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, slide block cylinder body 3 bottoms are provided with hydraulic cushion cylinder 5, and hydraulic cushion cylinder 5 bottoms are provided with hydraulic die cushion port connection 4, between hydraulic cushion cylinder 5 and lower adjusting nut 9, hydraulic die cushion piston 7 are installed, and 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 upper ball bowl 16 and lower ball bowl 21 by sphere-contact, union (screwed)bonnet (UB 15 is positioned at ball bowl 16 top positions and is connected with guide pillar screw rod 8 by the internal thread of guide pillar screw rod circular hole, thereby upper ball bowl 16 is carried out to axial limiting, guide pillar screw rod 8 tops are connected with worm gear gear ring 17 by outside spline tooth, Worm gear case 18 is fixed on press crown 28, also comprise Lubricating pump station 1, Lubricating pump station 1 is arranged on press machine bottom end rail 29 1 sides, lubricant oil filler opening 6 is opened on the sidewall of slide block cylinder body 3, Lubricating pump station 1 is connected with lubricant oil filler opening 6 and is implemented fuel feeding by oil inlet pipe 2, Lubricating pump station 1 is connected with the grease chamber in press crown 28 and is implemented oil return by return tube 13, guide pillar screw rod 8 inside offer one and connect oilhole 20, lower ball bowl 21 bottom centre positions offer filler opening 26, connecting oilhole 20 and filler opening 26 communicates, on hydraulic die cushion piston 7 sidewalls, offer piston opening 19, piston opening 19 respectively with the perforation oilhole 20 of guide pillar screw rod 8, lubricant oil filler opening 6 communicates.
The mode of lubrication oil circulation lubrication of the present invention is:
Lubricant oil enter channel: lubricant oil selflubricating pumping plant 1, along oil inlet pipe 2, from lubricant oil filler opening 6 enters slide block cylinder body 3, enters piston cavity along the piston opening 19 of hydraulic die cushion piston 7 sides; When lubricant oil constantly enters, piston cavity oil pressure is while reaching certain numerical value, lubricant oil rises along the perforation oilhole 20 of guide pillar screw rod 8, enters subsequently the filler opening 26 of lower ball bowl 21.
The confession oil lubrication of lower ball bowl: lubricant oil enters after the filler opening 26 of lower ball bowl 21, and lubricant oil from filler opening 26 out, is lubricated bulb ball bowl along lower ball bowl 21 spheres.
The export channel of lubricant oil: the lubricant oil that flows out continuously lower ball bowl 21, in the small space becoming in upper and lower ball bowl-type, oil level constantly rises, when oil pressure reaches after certain numerical value, lubricant oil is the Spherical Clearance with ball head connecting rod 14 from upper ball bowl 16, is back to the grease chamber in press crown 28; When lubricant level value of reaching a certain height of grease chamber, will reflux and enter in Lubricating pump station 1 along return tube 13, thereby realize the circulating lubrication of lubricant oil.
Circulating lubrication is cooling: Lubricating pump station 1, by the lubricant oil that refluxes from return tube 13 and, first filters, and then enters into fuel tank; The built-in Coolers of Lubricating pump station 1, the lubricant oil of extracting out from fuel tank enters Coolers, when oil temperature is dropped to given reference value, continues fuel feeding along oil inlet pipe 2, thereby realizes the cooling object of circulating lubrication.
Supplying lubricant formula of the present invention and supply route are all changed all of a sudden, lubricant oil relies on pressure feed and non-gravity supply, lubricant oil is supplied with but not from below to up from upper and upper supply, lubricant oil enters the inside of guide pillar screw rod 8 from connecting oilhole 20, the surface of contact finally entering from lower to upper between bulb ball bowl is lubricated cooling to bulb ball bowl, last lubricant oil is back to the grease chamber in press crown 28, reflux and enter in Lubricating pump station 1 through return tube 13, completed a circulation, lubricant oil can also be undertaken cooling by Coolers in Lubricating pump station 1.
As a further improvement on the present invention, as shown in Figure 3 and Figure 4, on lower ball bowl 21 spheres, offer multiple annular oil grooves 27, multiple annular oil grooves 27 are concentric structure, the center of circle of annular oil groove 27 overlaps with the center of circle of filler opening 26, between adjacent two annular oil grooves 27, pass through multiple radial groove 25 UNICOMs, the most inboard annular oil groove 27 near filler opening 26 is communicated with filler opening 26 by radial groove 25, under bulb ball bowl surface of contact gap levels off to zero condition, lubricant oil is entered by filler opening 26, then flow to annular oil groove 27 along radial groove 25, lubricant oil flows into the annular oil groove 27 of upper level in this way step by step, ball bowl 21 under final outflow, more even in order to allow lubricant oil supply with, radial groove 25 between adjacent two annular oil grooves 27 can be offered rational quantity as required.Adopt the manner can allow lubricant oil supply with more even, can be used as optimal way and use.
In order further to make lubricant oil supply with evenly, the radial groove 25 between two adjacent annular oil grooves 27 is evenly arranged to be offered.
For can being realized from lower to upper, the pressure of lubricant oil of the present invention supplies with, improve sealing effect, slide block gland end-face seal ring 22 is set on the lower end surface of slide block gland 12, at the inner side surface of slide block gland 12, slide block gland endoporus seal ring 23 is set, at the outer side surface of hydraulic cushion cylinder 5, hydraulic cushion cylinder cylindrical seal ring 24 is set.
