Description
Technical field
The present invention relates to a kind ofly provides the press of pressure source with air bag, belongs to press equipment.
Background technology
Present press such as crank press, friction press, hydraulic press, pressure forming machine, heat pressing forming machines, pressing machine, die casting machine etc., the nominal of this class machinery (work) pressure is provided by screw mechanism or toggle or hydraulic system, the complex structure of these mechanisms, the accuracy of manufacture requires very high, and cost is also very high.For the press of large-scale work top, often need a plurality of said mechanism or hydraulic cylinder to satisfy the stressed uniform requirement of its slide block (movable table), as the multiple spot forcing press.For the large pressing machine tool, the depth of parallelism of work top and slide block bottom surface is one of crucial technical indicator, for satisfying this specification requirement, should guarantee the perpendicularity of guide rail or guide pillar and work top, also will guarantee the perpendicularity of slide block bottom surface and road, side rail level, related size is many, and accumulated error is big, machining accuracy height, Installation and Debugging are very complicated; Area of work is big more, and the guide rail of slide block is just long more, the equipment big heaviness of body that will become, and the rigidity of workbench required also suitable height, therefore, the cost of press is high.
Patent No. ZL 200720095821.3 discloses a kind of gasbag-type forcing press that is used for sheet material processing, air bag directly acts on the processed sheet material, make sheet material obtain uniform pressure, only play the effect of a flexible pad, the nominal of forcing press (work) pressure is provided by cylinder.
Summary of the invention
Problem to be solved by this invention provides the press of a kind of air bag as pressure source, replace traditional screw mechanism or toggle or hydraulic system with air bag, rely on the guiding mechanism of high-precision guide pillar guide pin bushing or guide rail class to guarantee the depth of parallelism between slide block (movable table) working face and the work top no longer fully, rigidity to workbench requires also to reduce accordingly, thereby simplified the structure of press greatly, reduced the manufacturing cost of press, and the suitable press of making ultra-large type work top and tens thousand of tons of pressure, to satisfy aircraft, shipbuilding, the needs of process industries such as automobile.
For addressing the above problem, the present invention by the following technical solutions:
A kind of gas-bag pressure machine is characterized in that: described gas-bag pressure machine is made up of framework, slide block and air bag, and its nominal (work) pressure is provided by air bag.
Below be the further improved technical scheme of such scheme:
The framework of described gas-bag pressure machine is made of crossbeam, column, base.
The air bag that described gas-bag pressure machine adopts is pancake, and promptly two of air bag stress surfaces are parallel, and the shape of the stress surface of air bag can be rectangle or circular or oblong, the air bag side be provided with for fill, the Valve for aerocyst of draining (gas) usefulness.Department's clothes equipment is air compressor or high-pressure hydraulic pump.
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 of the present invention 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.
The invention will be further described below in conjunction with drawings and Examples:
