Abstract
The invention relates to an idle-stroke forward shunt system for an artificial diamond press. The idle-stroke forward shunt system comprises an oil tank, a plunger pump, a through one-way valve, a forward shunt valve, a high-pressure relief valve, an extra-high pressure controlled one-way valve, a working cylinder and a piston, wherein the oil tank, the plunger pump, the through one-way valve, the forward shunt valve, the high-pressure relief valve, the extra-high pressure controlled one-way valve and the working cylinder are sequentially connected, and the piston is positioned in the working cylinder; the forward shunt valve is connected with the oil tank through a shunt pipe. According to the idle-stroke forward shunt system for the artificial diamond press, the forward shunt valve is additionally arranged, so that the amount of travel of the piston in the working cylinder can be controlled more precisely, the centering, synchronization and stability of hydraulic equipment are ensured, and the idle-stroke forward inertia of the piston is reduced.
Description
Technical field
The present invention relates to a kind of composition system of man-made diamond pressing machine, be specifically related to a kind of man-made diamond pressing machine idle running separate system that advances, belong to diamond machined equipment technical field.
Background technique
The man-made diamond pressing machine of prior art adopts the direct driven plunger of hydraulic jack conventionally, makes the control accuracy of piston stroke lower; Meanwhile, speed while advancing due to piston idle running, so not only energy consumption is high, and the top hammer of diamond press easily impacts synthetic piece, causes synthetic piece chipping and scrap.
Therefore,, for solving the problems of the technologies described above, the necessary one that provides has the structure improved man-made diamond pressing machine idle running separate system that advances, to overcome described defect of the prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of accurately control piston stroke, the man-made diamond pressing machine idle running that the reduces inertia separate system that advances.
For achieving the above object, the technological scheme that the present invention takes is: a kind of man-made diamond pressing machine idle running separate system that advances, and it comprises fuel tank, plunger pump, inline check valve, the diverter valve that advances, high-pressure overflow valve, ultrahigh pressure controllable check valve, clutch release slave cylinder and piston; Wherein, described fuel tank, plunger pump, inline check valve, the diverter valve that advances, high-pressure overflow valve, ultrahigh pressure controllable check valve are connected successively with clutch release slave cylinder; Described piston is positioned at clutch release slave cylinder; The described diverter valve that advances is connected with fuel tank by a ram's horns.
Compared with prior art, the present invention has following beneficial effect: man-made diamond pressing machine idle running of the present invention is advanced separate system by setting up the diverter valve that advances, thereby can control more accurately the walking amount of clutch release slave cylinder inner carrier, guarantee centering, synchronism and the stability of hydraulic equipment, reduce the inertia that the idle running of piston is advanced.
Accompanying drawing explanation
Fig. 1 is the advance schematic diagram of separate system of man-made diamond pressing machine idle running of the present invention.
Embodiment
Refer to shown in Figure of description 1, the present invention is a kind of man-made diamond pressing machine idle running separate system that advances, and it is made up of several parts such as fuel tank 1, plunger pump 2, inline check valve 3, the diverter valve 4 that advances, high-pressure overflow valve 5, ultrahigh pressure controllable check valve 6, clutch release slave cylinder 7 and pistons 8.
Wherein, described fuel tank 1, plunger pump 2, inline check valve 3, the diverter valve 4 that advances, high-pressure overflow valve 5, ultrahigh pressure controllable check valve 6 are connected successively with clutch release slave cylinder 7.In described fuel tank 1, store hydraulic oil.Described plunger pump 2 is for extracting the hydraulic oil in fuel tank 1.Described inline check valve 3 can prevent hydraulic oil reverse flow.Described high-pressure overflow valve 5 can effectively avoid the pressure in system excessive, causes the damage of equipment.Described ultrahigh pressure controllable check valve 6 is for controlling the amount of hydraulic oil input service cylinder 7.
Described piston 8 is positioned at clutch release slave cylinder 7, promotes pistons work by the hydraulic oil in clutch release slave cylinder 7.
The man-made diamond pressing machine idle running of the present invention greatest improvement part of the separate system diverter valve 4 that advances described in being to have set up that advances, this diverter valve 4 that advances is connected with fuel tank 1 by a ram's horns 9.
The advance working principle of separate system of man-made diamond pressing machine idle running of the present invention is as follows: in the time that piston 8 idle runnings are advanced, first allow piston advance fast, by the time after advancing to a certain degree, open the diverter valve 4 that advances, part hydraulic oil is back in fuel tank 1 by the diverter valve 4 that advances, thereby allow piston 8 slowly advance, reduce piston 8 inertia bringing that advances fast, more accurate control piston 8 strokes.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
