Detailed description of the invention
Be below a specific embodiment of the present utility model, now by reference to the accompanying drawings the utility model be described further.
As shown in Figure 1, a kind of novel inaccessible hydraulic extrusion press, frame 1 comprises the base of lower end and four columns positioned opposite; The lower squeeze cylinder 10 of vertical placement is arranged in base, and lower squeeze cylinder 10 piston rod upward; Base is fixed detachable workbench backing plate 11, as shown in Figure 5, workbench backing plate has the jogger hole conveniently ejecting workpiece, a manhole in the middle of it, surface has the T-slot in order to fixed mould thereon, and the piston rod of lower squeeze cylinder 10 is relative with the manhole in the middle of workbench backing plate 11; Be fixed with the master cylinder 6 vertically placed in frame 1 upper end, down, slide block 5 is fixed in piston rod end to master cylinder 6 piston rod; As shown in Figure 3, slide block 5 is rectangle, and four ribs that it is vertical are respectively provided with an adjustable guide plate 4, as shown in Figure 2, and each guide rail 3 fixing the adjustable corner octahedral that coordinates with guide plate 4 inside frame 1 column; It is inner that upper squeeze cylinder 2 is arranged on slide block 5, detachable slide block backing plate 12 is arranged on slide block 5 lower end, as shown in Figure 4, be manhole in the middle of slide block backing plate 12, its lower surface has T-slot, upper squeeze cylinder 2 piston rod is vertically arranged down, and upper squeeze cylinder 2 piston rod is relative with the manhole in the middle of slide block backing plate 12; Lower squeeze cylinder 10, upper squeeze cylinder 2 are connected power station 8 and electric box 14 with master cylinder 6; Power station 8 is fixed on the top of frame 1, and power station adopts block for two-port cartridge, have compact conformation, response fast, in let out little, be active in one's movements reliable, the advantage such as flow is large, contamination resistance is strong, working service is convenient, the life-span is long; Be provided with the platform rail 7 be fixed on frame 1 top in power station 8 surrounding, platform rail 7 comprises security platform, coaming plate, and coaming plate adopts buckle type structure, good looking appearance; Electric box 14 comprises dynamical system and control system two parts, and power section comprises control general supply, the start and stop of each motor and protection switch etc., and control system can complete the control to the whole action of this machine; Frame 1 is fixed with instrument box 13, is provided with in instrument box 13 and is respectively used to pressure display, the shock-proof pressure gauge of Stress control and pressure regulation, electro connecting pressure gauge and remote pressure regulating valve; Frame 1 side is fixed with safety climbing ladder 9.
Using method:
When needs adopt closing mould forging extrusion process, start hydraulic pump motor in power station, pump No Load Start.Master cylinder cavity of resorption oil flows back to power station, and slide block under gravity idle running declines fast, and now master cylinder epicoele forms negative pressure, and the low pressure oil at overhead power station is through prefill valve to master cylinder epicoele topping up, and the oil that pump exports simultaneously also enters master cylinder epicoele.Slide block drops to certain position, touch travel switch, slide block does not rely on Action of Gravity Field and declines, pressure oil that pump exports must be relied on piston pressurization, slide block just can be made to decline, and the decrease speed of slide block slow down, now, the speed of slide block depends on the fuel delivery of pump, and the flow changing pump gets final product the movement velocity of adjusting slider.In work pressure process, the pressure in master cylinder depends on outside deformation drag.Master cylinder pressure arrives certain numerical value, and upper squeeze cylinder and lower squeeze cylinder simultaneously subtend eject, and realize closing mould forging extrusion process.Master cylinder epicoele oil flows back to oil cylinder, and pressure starts to decline, and when master cylinder epicoele pressure unloads to certain value, slide block starts backhaul.Master cylinder backhaul terminates, and slide block touches travel switch, and lower squeeze cylinder performs and ejects action, and so far, whole technological action all completes.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvement and optimization, these improve and optimize and should be considered as protection domain of the present utility model.
