Described gas-bag pressure machine adopts the individual layer air bag, and the stroke of its slide block is between 2~500mm.
Described gas-bag pressure machine can adopt multi-layer airbag to strengthen the stroke of slide block.
The air bag of described gas-bag pressure machine is placed between base and the slide block, and the masterpiece of air bag is used for slide block (movable table), and the slide block acting that moves upward passes to mould and workpiece with power.
The air bag of described gas-bag pressure machine is placed between crossbeam and the slide block, and the masterpiece of air bag is used for slide block (movable table), and slide block moves downward acting, and power is passed to mould and workpiece.
The framework of described gas-bag pressure machine can be closed or open.
When the mold base of described gas-bag pressure machine is enough big, can omit slide block (movable table), that is to say that mould and slide block are one.
The adopted guide rail of described gas-bag pressure machine or guide pillar are slider guide.
The slide block of described gas-bag pressure machine floats, and also can rely on the guider guiding of mould.
The depth of parallelism between the slide block of described gas-bag pressure machine (movable table) working face and the corresponding work top guarantees by the pressure of air bag equalization.
Beneficial effect
Gas-bag pressure machine described in the utility model has omitted transmission mechanism, guiding mechanism, the servo structure of bulky complex, and its structure is very simple, and requirement on machining accuracy is low, and the related size of complete machine is few, only requires that the flatness that guarantees work top gets final product.Because the pressure of air bag equates everywhere, as long as workpiece to be machined symmetrical structure or process layout be symmetry substantially, only depend on parallel between plane that the air bag self characteristics can guarantee slide block (movable table) and the corresponding work top, rather than lean on the forced guiding of guiding mechanism to guarantee, especially big, extremely convenient to flatness and the demanding workpiece of the depth of parallelism in working (finishing) area;
The air bag of gas-bag pressure machine places slide block (movable table) bottom, and slide block is done motion acting vertically upward, has saved the compensating cylinder that common large pressing machine tool moves downward the slide block of acting, has reduced function and has expended, and makes the structure of press more simple;
The stroke of the slide block of gas-bag pressure machine (movable table) and nominal (work) pressure can be set flexibly according to the parameter of air bag, and the stroke of general air bag can reach 500mm, can make the stroke of slide block satisfy different process requirements;
It is not have in the course of work to impact that gas-bag pressure machine also has characteristics, in the service life that can improve moulds such as processing and forming greatly, is particularly suitable for the processing of metalwork pull and stretch;
The height of gas-bag pressure machine and weight need not to build huge reinforced concrete foundation and tall and big factory building like that as press less than 50% of usual pressure machinery, as long as its installation requirement can be satisfied in the ground of smooth sclerosis;
The air bag work of gas-bag pressure machine is pressed can reach 20MPa, can be covered with slide block (movable table) to greatest extent, and active area is big, and stressed even, the operating pressure of the big more press of slide block area is just big more, is the reliable pressure source of press;
Gas-bag pressure machine simple in structure, in light weight, its manufacturing cost is very cheap, rough measuring and calculating, a wide-bed-type press brake face large-tonnage press, for example work top is 3*7m, and nominal pressure is that the cost of 10000 tons gas-bag pressure only is sixth to five/one of crank multiple spot forcing press, and mounting cost is cheap.
