Abstract
The utility model discloses an oil return mechanism of a forcing press guide pole, which belongs to the technical field of a forcing press, and comprises a guide pole, wherein, a copper sleeve is arranged at the periphery of the guide pole and is fixed in a central sleeve which is fixed to a machine body, the lower side of the central sleeve is fixed with a lower end cover sleeved on the guide pole, an upper and a lower sealing rings are arranged between the lower end cover and the guide pole, and the lower side of the lower end cover is provided with a sealing ring gland bush; the lower end cover, the central sleeve and the copper sleeve are respectively provided with an oil inlet channel which is communicated with each other, and the oil inlet channel of the copper sleeve is communicated with the gap between the copper sleeve and the guide pole; the inner side of the lower end cover between the two sealing rings is provided with an annular oil groove along the circumference direction, and an oil return channel communicating the annular oil groove is arranged in the lower end cover. When the oil return mechanism works, lubricating oil with certain pressure reaches the gap between the copper sleeve and the guide pole for lubricating perfectly, and a part of lubricating oil flows downwards into the annular oil groove and then flows away through the oil return channel. The oil return mechanism can ensure that the sealing rings are durable and ensure that oil return is clean, and can be used on the forcing presses.
Description
Technical field
The utility model relates to a kind of forcing press, specially refers to the oil return mechanism of PRESS PLUNGER.
Background technology
The guide pillar oil return mechanism of the forcing press of existing press technologies, a kind of is the leak stopping formula, its structure mainly comprises guide pillar, the guide pillar periphery is provided with copper sheathing, copper sheathing is fixed in the center, center and fuselage fix, the center downside is fixed with the bottom end cover that is sleeved on the guide pillar, is provided with sealing ring between bottom end cover and the guide pillar, and the bottom end cover downside also is provided with the sealing ring gland, bottom end cover, be respectively equipped with the oil inlet passage that is connected on center and the copper sheathing, oil inlet passage on the copper sheathing is connected the gap between copper sheathing and the guide pillar, during this device work, directly leans on the sealing function of the sealing ring between bottom end cover and the guide pillar, lubricating oil is clamp-oned firmly in the oil sump tank of copper sheathing top setting, but along with the raising of long operation or lathe speed, the phenomenon of oil seepage will appear, at this moment between bottom end cover and guide pillar, has only the replacing oil sealing, just can reach the effect of sealing, when work, because oil pressure ratio is higher, also easily with the sealing ring extrusion damage, its dependability is poor; Another kind of guide pillar oil return mechanism is oil return basin of increase below bottom end cover, and the lubricating oil of seepage flows in the oil return basin, is back in the main fuel tank by the oil return basin again, though this mechanism also can reach the oil return effect, the unclean shortcoming of outward appearance ugliness, oil return is arranged.
The utility model content
The purpose of this utility model provides a kind of PRESS PLUNGER oil return mechanism, makes the sealing ring durable, and oil return is clean.
The purpose of this utility model is achieved in that the PRESS PLUNGER oil return mechanism, comprise guide pillar, the guide pillar periphery is provided with copper sheathing, copper sheathing is fixed in the center, center and fuselage fix, the center downside is fixed with the bottom end cover that is sleeved on the guide pillar, be provided with sealing ring between bottom end cover and the guide pillar, the bottom end cover downside also is provided with the sealing ring gland, bottom end cover, be respectively equipped with the oil inlet passage that is connected on center and the copper sheathing, oil inlet passage on the copper sheathing is connected the gap between copper sheathing and the guide pillar, described sealing ring includes twice up and down, bottom end cover inboard between the two seals circle is provided with annular oil groove along its circumferencial direction, is provided with the drainback passage of connecting annular oil groove in the bottom end cover.
During the utility model work, can slide relatively between copper sheathing and the guide pillar, lubricating oil with certain pressure enters from oil inlet passage, and arrive in the gap between copper sheathing and the guide pillar, good lubrication is provided, avoid wearing and tearing and heating between copper sheathing and the guide pillar, a part of pressure oil upwards flows, and the working method of itself and prior art is identical; The lubricating oil of another part is passed down through one sealing ring and enters in the annular oil groove, following one sealing ring can stop that lubricating oil flows downward along the gap between itself and the guide pillar, lubricating oil in the annular oil groove can flow away from drainback passage, can flow away naturally or siphon away by vacuum plant, it is recycling that collection enters fuel tank.The utility model can keep the sealing ring durable, between last one sealing ring and the guide pillar suitable gap can be arranged, allow it that a certain amount of leakage is arranged, can strengthen lubricating, and can in time take away heat, following one sealing ring be not owing to be subjected to the pressure of lubricating oil, and its use is more reliable, thereby can keep sealing ring durable more; Simultaneously, owing to adopted sealing oil return mode, make oil return cleaner.
The utility model can be applicable on the forcing press.
Description of drawings
Fig. 1 is a structural scheme of mechanism of the present utility model.
Wherein: 1 fuselage, 2 center, 3 copper sheathings, 4 guide pillars, 5 drainback passages, 6 bottom end covers, 7 sealing ring glands, 8a, 8b sealing ring, 9 annular oil grooves, 10,11,12 oil inlet passages.
The specific embodiment
As Fig. 1, be the PRESS PLUNGER oil return mechanism, comprise guide pillar 4, guide pillar 4 peripheries are provided with copper sheathing 3, copper sheathing 3 is fixed in the center 2, center 2 fixes with fuselage 1, center 2 downsides are fixed with the bottom end cover 6 that is sleeved on the guide pillar 4, be provided with two seals circle 8a and 8b up and down between bottom end cover 6 and the guide pillar 4, bottom end cover 6 downsides also are provided with sealing ring gland 7, sealing ring gland 7 can be pushed down down sealing ring 8a one, bottom end cover 6, be respectively equipped with the oil inlet passage 10 that is connected on center 2 and the copper sheathing 3,11,12, the gap that oil inlet passage 12 on the copper sheathing is connected between copper sheathing 3 and the guide pillar 4, the bottom end cover inboard between two seals circle 8a and the 8b is provided with annular oil groove 9 along its circumferencial direction, is provided with the drainback passage 5 of connecting annular oil groove 9 in the bottom end cover 6.
During work, can slide relatively between copper sheathing 3 and the guide pillar 4, lubricating oil with certain pressure enters from oil inlet passage 10,11,12, and arrive in the gap between copper sheathing 3 and the guide pillar 4, good lubrication is provided, avoid wearing and tearing and heating between copper sheathing and the guide pillar, a part of pressure oil upwards flows, and oil return; The lubricating oil of another part is passed down through one sealing ring 8b and enters in the annular oil groove 9, following one sealing ring 8a can stop that lubricating oil flows downward along the gap between itself and the guide pillar 4, lubricating oil in the annular oil groove 9 can flow away from drainback passage 5, can flow away naturally or siphon away by vacuum plant, it is recycling that collection enters fuel tank.Between last one sealing ring 8b and the guide pillar 4 suitable gap can be arranged, allow it that a certain amount of leakage is arranged, can strengthen lubricated, and can in time take away heat, following one sealing ring 8a be not owing to be subjected to the pressure of lubricating oil, and its use is more reliable, thereby can keep sealing ring durable more; Simultaneously, owing to adopted sealing oil return mode, make oil return cleaner.
