Description
Technical field
The invention belongs to sheet material liquid-filling shaping technical field, particularly a kind of composite oil cylinder and the hydraulic press that has the double-action function with composite oil cylinder.
Background technique
It is to utilize fluid pressure to make a kind of plastic working technique of component shaping that fluid power is shaped, and by the difference of using stock, can be divided into the shaping of plate fluid power, the shaping of housing fluid power and pipe fluid power shaping three types.The fluid power forming technique is applied to produce, abroad developed country be also since last century the nineties, carried out case study by Harbin Institute of Technology's early start in 1999 in China, be applied to industrial production or recent years inchoate.In the hydraulic press industry, traditionally plate fluid power shaping hydraulic machine is called liquid-filling shaping hydraulic machine, housing fluid power shaping hydraulic machine is called the water swelling machine, pipe fluid power shaping hydraulic machine is called the internal high pressure forming hydraulic press.They are all the internal high pressure forming hydraulic presses in essence.
Liquid-filling shaping hydraulic machine also has the topping up of being called hydraulic drawing press or liquid hydraulic drawing press.Its technological method is to be full of liquid in die, utilizes punch to drive and pulls the mould-forming method of setting up reverse hydraulic pressure when material enters die.The rear part resilience that is shaped is few, and precision is high.Present domestic liquid-filling shaping hydraulic machine also is in the prototyping state substantially, as supply of commodities market also seldom, and be all the structural type of four beam four posts basically.
The liquid-filling shaping hydraulic machine of prior art mainly comprises two classes, the first is that four beam four posts, two side cylinders are to the liquid-filling shaping hydraulic machine of flanging beam pressurization form, because limited by topology layout, the force bearing point of flanging cylinder must want the center of tripping side bar far away, for the amount of deformation of controlling the flanging beam will be done the size of flanging beam very large, machine will be done very heavyly, and manufacture cost increases; The second is that a plurality of little flanging cylinder between four beam four posts, walking beam and flanging beam is to the liquid-filling shaping hydraulic machine of flanging beam pressurization form, limited by topology layout, distance between walking beam and flanging beam becomes larger, the height of complete machine will increase, and because the oil cylinder number is many, oil pipe connects complicated and is difficult to arrange attractive in appearancely, and cost also will increase.。
The oil cylinder that is used for now hydraulic press is all simple function, complete stretch or pressing function be master cylinder, that completes the flanging function is the flanging oil cylinder, that completes the thruster function is the thruster oil cylinder, that completes material returned function is material returned oil cylinder or dnockout oil cylinder etc.Stretch in tradition, during flanging, realize that the shaping of sheet material first drives the pressed edge ring flanging by the flanging crossbeam often as the liquid-filling shaping hydraulic machine of prior art, then stretch to realize part forming by stretching slide block drive stretching slide block.Machine except needs pressed edge ring and stretching slide block, also need to stretch crossbeam and flanging crossbeam, the complex structure of machine, the relative positional accuracy between pressed edge ring and drawing die is difficult to ensure card, makes the parts size precision that processes relatively poor.
The existing liquid-filling shaping hydraulic machine that improves structure is realized the coaxial linkage of stretching, flanging, but it is to realize by a kind of structure that is called the flexible composite oil cylinder of two-stage, two-stage piston rod with the flexible composite oil cylinder of two-stage is used as stretching and flanging function respectively, pressure tonnage between stretching hydraulic system and flanging hydraulic system is influenced each other, cause stretching or flanging pressure all to be difficult to control, although can realize stretching and the flanging once-through,, increased tonnage and the cost of hydraulic machinery.
