Description
Technical field
The utility model relates to the compression molding device of powder metallurgy, ceramic material, magnetic material etc., is specially a kind of isostatic pressing machine.
Background technology
Isostatic pressing machine is the liquid medium that blank is placed this machine high pressure chest, makes around the workpiece and the static pressure that all is subjected to the superhigh pressure liquid medium up and down, makes its density even, dense structure.
Existing isostatic pressing machine comprises framework usually, is positioned at the high pressure chest of framework, it is to carry out between the upper and lower beam of framework that dress is got material, can suppress the bigger workpiece of length if make these static pressure machines, except that the high pressure chest degree of depth increases, it is very high that framework also will be done, to realize packing into and taking out of workpiece, not only make machine volume huge, and the increase manufacturing cost.
For solving big length workpiece compacting problem, the portable and two kinds of isostatic pressing machines that are exclusively used in the big length workpiece of compacting of cap-rotating type of framework are arranged in the prior art; The portable isostatic pressing machine of framework is when packing into or takes out workpiece, and framework can be removed and expose high pressure chest, is convenient to packing into and taking out of big length workpiece, and during work, framework moves into place, and begins after the high pressure chest centering to pressurize; Cap-rotating type isostatic pressing machine, its job order are earlier workpiece to be loaded on high pressure chest, seal high pressure chest is suitable for reading with spiral cover again, then, inject hydraulic oil from the high pressure chest bottom, pressurize to workpiece, after pressurization finishes, twist and remove loam cake, take out workpiece again.Though more than the isostatic pressing machine of two kinds of structures can suppress big length workpiece, the dress of workpiece is got to be needed by artificial or with the electric hoist lifting, dress is got the workpiece inconvenience, production efficiency is low, labour intensity is big, and the complex structure of portable isostatic pressing machine particularly.Above-mentioned two kinds of static pressure machines all adopt superpressure oil pump directly to the high pressure chest pressurization, and its shortcoming is the hydraulic system vulnerable to pollution, and medium must adopt expensive transformer oil, high-pressure pump cost height, maintenance cost height in the high pressure chest.
Summary of the invention
The utility model solves existing isostatic pressing machine and particularly suppresses the problem that exists on the isostatic pressing machine structure of big length workpiece, and a kind of isostatic pressing machine of architecture advances is provided.
The utility model is to adopt following technical scheme to realize: isostatic pressing machine, the pressue device that comprises framework, is positioned at the high pressure chest of framework, communicates with high pressure chest through high pressure chest bottom oil duct, be fixed with bracing frame at framework upper, be fixed with the input and output material oil cylinder on bracing frame top, the piston rod end of input and output material oil cylinder is fixed with the high pressure chest lid, is fixed with charging basket on the lower surface of high pressure chest lid.By control input and output material oil cylinder high pressure chest lid and charging basket are risen, because the height space of bracing frame is arranged, charging basket can rise to more than the framework, directly workpiece is put into or taken out charging basket, and it is convenient, fast that dress is got workpiece; The input and output material oil cylinder descends and to make charging basket enter the sealing suitable for reading with high pressure chest of high pressure chest and high pressure chest lid, and pressue device injects hydraulic oil through the oil duct of high pressure chest bottom in high pressure chest, and workpiece such as finishes at static pressure in the hydraulic oil medium.Because the existence of bracing frame, charging basket has the sufficient rising space, gets the needs of big length workpiece to satisfy dress, and when the high pressure chest degree of depth was increased, the framework of press did not increase substantially, thereby has reduced the manufacturing cost of press.
Pressue device is made of pressurization oil cylinder and the plunger case that is fixed in pressurization oil cylinder bottom, and the piston rod of pressurization oil cylinder is exactly the plunger of plunger case, and plunger case communicates with high pressure chest through high-pressure pipeline.The pressure that the ratio of this pressue device by pressurization oil cylinder piston area and piston rod area of section will apply pressure on the pressurization oil cylinder piston amplifies on the after-applied oily medium in high pressure chest, make and adopt common hydraulic jack (pressurization oil cylinder) just can in high pressure chest, produce super-pressure, overcome the defective that the available technology adopting superpressure oil pump is directly exerted pressure and brought to high pressure chest.
Be provided with the fuel reserve tank that communicates with plunger case in the pressue device, have the level that communicates, vertical oil duct in the end of compressed oil cylinder piston rod, be used to link up the position of the oil duct of fuel reserve tank and plunger case on the plunger case, open the corresponding position of its end horizontal oil duct when the piston rod with the pressurization oil cylinder rises to extreme position, simultaneously, on the high-pressure pipeline between plunger case and high pressure chest, be connected with hydraulic control one-way valve.Fuel reserve tank is used for deposit and waits the static pressure liquid medium.Hydraulic control one-way valve is except that pressure release, and liquid can only unidirectionally pass through, and therefore, the effect of hydraulic control one-way valve is to make the pressurization oil cylinder can realize repeatedly pressurizeing, to adapt to the not demand of co-content and different pressures of high pressure chest.When the piston rod of pressurization oil cylinder rises to high limit position, fuel reserve tank is by the level of oil duct on the plunger case and piston rod end, vertical oil duct and plunger case UNICOM, to realize repairing and the oil return between fuel reserve tank and plunger case, piston rod is descending, when its end horizontal oil duct is crossed sealing ring, i.e. cut-out is got in touch with fuel reserve tank.
Isostatic pressing machine described in the utility model can be suppressed the workpiece of growing up, compared with prior art, when the high pressure chest degree of depth is big its device height particularly the frame height increase not quite or not increase, and simple in structure, low cost of manufacture; Provide feeding, drawing mechanism for oneself, dress is got and is expected that the operating space is open, easy and simple to handle; Pressuring method is reasonable, can realize super-pressure in the high pressure chest with the normal hydraulic oil cylinder; Can realize repeatedly pressurizeing, be applicable to the not isostatic pressing machine of co-content, different pressures requirement of high pressure chest.Wait static pressure oil medium and the in-oil cylinder hydraulic oil of pressurization in these static pressure machine high pressure chests are isolated mutually, so the hydraulic oil of hydraulic system is not subjected to the influence of medium pollution in the high pressure chest, can improve the service life of pressurization oil cylinder.
