Abstract
The utility model relates to the technical field of hydraulic transmission in mechanical automatic control, in particular to a hydraulic cylinder technology of a bending machine, which mainly comprises a guide sleeve, an adjusting nut, a cylinder body, a screw shaft, a piston, a spiral cover, a worm wheel, a worm, a top cover and the like, wherein two sealing grooves are respectively arranged on the upper part of the piston and the guide sleeve, and a combined sealing piece and a sealing ring are respectively arranged in the grooves; a plurality of unloading oil grooves are arranged on the adjusting nut; the worm gear case is provided with a through hole, and an oil supply device is arranged in the through hole. The hydraulic cylinder of the bending machine has adjustable stroke, two seals are respectively arranged on the piston and the guide sleeve, so that the hydraulic cylinder is impact-resistant under a high-pressure quick working state, and the hydraulic cylinder is prevented from sliding downwards under the condition of no stopping. The adjusting nut is provided with a plurality of unloading oil grooves, so that internal resistance is prevented, an oil supply device is added, and worm gear transmission is wear-resistant, so that the integral comprehensive performance of the bending machine is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to hydraulic transmission technology field in the automatic control of machinery, relates in particular to bender oil hydraulic cylinder technology.
Background technique
The bender oil hydraulic cylinder that in common bender, uses, in the using process, a combination seal or the sealing of two Yx-shaped ring are only adopted with sealing in the hole of oil hydraulic cylinder, though the former high voltage bearing impact, not anti-low pressure, incompatibility operating on low voltage, latter's incompatibility high pressure is worked fast, easily produces and leaks; The adjusting nut end face does not have the off-load oil groove, thereby influences backhaul.When the backhaul starting point was obstructed, lathe can produce the internal resistance stuck phenomenon, because Worm gear case does not have fuel supplement device, worm and gear was turned round, the very fast proper functioning that influences lathe, reduction of service life under unlubricated oil condition.
Summary of the invention
The purpose of this utility model provides a kind of anti-fall, shock-resistant, anti-internal resistance and the anti-anti abrasive bender oil hydraulic cylinder of worm and gear transmission.
The utility model mainly comprises guide sleeve, adjusting nut, cylinder body, screw axis, piston, spiral cover, worm gear, worm screw and top cover, all has two seal grooves on piston top and guide sleeve, is respectively arranged with combination seal and seal ring in the groove; On adjusting nut, be provided with several off-load oil grooves; On Worm gear case, have through hole, be provided with fuel supplement device in the hole.
This bender hydraulic cylinder travel can regulate respectively is provided with the sealing of two roads on piston and guide sleeve, make oil hydraulic cylinder shock-resistant under the quick working state of high pressure, and oil hydraulic cylinder is anti-fall under the situation of shutting down.Offer several off-load oil grooves on adjusting nut, anti-again internal resistance increases fuel supplement device, makes worm drive wear-resistant, thereby has improved bender whole synthesis performance, increases the service life.
Because the combination seal that the bender oil hydraulic cylinder adopts is that rectangular seal ring combines by two cross sections, sealing surface is not only wide but also thick, good sealing effect.Other seal ring adopts Yx shape circle, wear resistance, sealing height.
Description of drawings
Fig. 1 is a bender hydraulic cylinder structure schematic representation;
Fig. 2 is the piston sealing structure schematic representation;
Fig. 3 is guide sleeve and adjusting nut structural representation.
Among the figure, 1 is guide sleeve, and 2 is adjusting nut, and 3 is cylinder body, and 4 is screw axis, and 5 is piston, 6 is spiral cover, and 7 is spacer, and 8 are the card key, and 9 is Worm gear case, and 10 is worm gear, and 11 is worm screw, 12 is top cover, and 13 is oil filler, and 14 is combination seal, and 15 is seal ring, 16 off-load oil grooves.
Specific embodiment
All have two seal grooves on guide sleeve 1 and piston 5, be provided with combined seal ring 14 and Yx shape seal ring 15 in the groove, have through hole on Worm gear case 9 tops, oil filler 13 is housed in the hole, position alignment worm screw 11 with worm gear 10 Surface of action, is convenient to refuel.
This bender hydraulic cylinder travel can regulate is regulated worm screw 11 and is driven worm gear 10 rotations, drives screw axis 4 simultaneously and rotates, and adjusting nut 2 slides in piston 5 like this, thereby stroke has obtained adjusting.In piston 5 chambeies during oil-feed, be obstructed in backhaul for preventing piston 5, set up several off-load oil grooves 16 at the pressurized end face of adjusting nut 2.Combination seal 14 on the piston 5 and Yx RunddichtringO 15 have guaranteed that the bender oil hydraulic cylinder is shock-resistant under the quick situation of high pressure; Under the situation of shutting down, piston 5 does not glide.
Claims (2)
1, bender oil hydraulic cylinder, mainly comprise guide sleeve, adjusting nut, cylinder body, screw axis, piston, spiral cover, worm gear, worm screw and top cover, it is characterized in that on piston top and guide sleeve, all having two seal grooves, be respectively arranged with combination seal and seal ring in the groove; On adjusting nut, be provided with several off-load oil grooves; On Worm gear case, have through hole, be provided with fuel supplement device in the hole.
2, bender oil hydraulic cylinder according to claim 1 is characterized in that: combination seal is that rectangular seal ring combines by two cross sections, and other seal ring is shaped as Yx shape circle.
