Description
Technical field
The present invention relates to the hydraulic system of plastic bottle cap molding press.Specifically, a kind of pressure distributor controlling cylinder action is related to.
Background technique
Although the development of existing plastic bottle cap molding press industry has had certain progress, technical merit has still been in the relatively backward stage.Major embodiment is that job efficiency is low, and manufacturing efficiency is low.And these performance index except with machine construction, being designed with of mould structure outside the Pass, topmost reason and hydraulic system be designed with close relationship; Through data of literatures such as retrieval Chinese patent CN201645731U, CN102133784B, CN101570043B, CN201405478Y, in conjunction with investigation, the actual service condition understanding plastic bottle cap molding press, find that the conceptual design of its hydraulic system probably has two kinds:, a kind of is mechanical type two position and four-way reversing valve of use standard and the oil circuit of swivel joint formation; Another kind is the oil circuit using radial flow distributor.This two schemes is different on mode of execution, but hydraulic principle is just the same, all belongs to single stage of pressure system (see Fig. 1).The hydraulic system concluding prior art has following shortcoming:

Two, adopting the scheme of radial flow distributor, is in fact the structure of radial flow, axial isolation, radial clearance seals, axial seal sealing.Whether pressure oil, oil return can be depended on the size in axial isolation section radial fit gap by effective isolation.Gap is little, and parts depreciation is fast; Gap is large, and oil film rigidity is not enough, leaks large, easily causes that working condition pressure is low, system heating value is large.Obtain desirable matching gap, require high to process equipment, part processing precision, bearing clearance rank etc., uncompensated function after wearing and tearing.
Three, hydraulic principle is designed to single stage of pressure system, and load can only lean on the oil return resistance of the piston of oil cylinder, the surface friction drag of piston rod and oil cylinder to produce.When complete machine rotating speed improves, working condition pressure significantly declines, and does not provide the high pressure needed for plastic bottle closure shaping, and article formation difficulty, defect is many, can not meet technological requirement completely, and can only work in low engine speed range, manufacturing efficiency is low.If hydraulic principle to be designed to high and low pressure system layout (see Fig. 2), each oil cylinder two-position four-way valve commutates, and carry out high low pressure with a two position three-way valve and switch, program principle is set up, but concrete enforcement quite difficulty.
