Abstract
The invention discloses a cooling machining die capable of maintaining pressure and used for a top-layer foil of an elastic foil gas bearing. A locating ring is matched on an upper die and connected with the upper die through bolts. The locating ring and a groove of a pressing plate of a hydraulic tensile machine are matched for locating. A half-cylinder is arranged on the lower surface of the upper die. A concave surface which is matched with the half-cylinder is arranged on a lower die. A groove is formed in the concave surface and used for installing the top-layer foil. A pull rod penetrates through a tensile bar of the hydraulic tensile machine, the pressing plate, the upper die and the lower die. The pressing plate, the upper die and the lower die are fixed through an upper nut and a lower nut. When the cooling machining die is used, the top-layer foil is clamped in the groove of the lower die and attached to the inner surface of the lower die, polyfluortetraethylene plates are placed on the top-layer foil, the hydraulic tensile machine is started , the tension of the tensile bar is utilized to make the upper die and the lower die mutually squeeze, the polyfluortetraethylene plates in the half-cylinder and the lower die are deformed, the polyfluortetraethylene plates and the inner cambered surface of the lower die are squeezed, and the top-layer foil is formed. The cooling machining die has the advantages of being simple in structure and low in cost.
Description
Technical field
The invention belongs to can pressurize cold working technical field of mold, be specifically related to a kind of for top foil of elastic foil gas bearing can pressurize cold working mould.
Background technology
Elastic foil bearing has good adaptivity, can under high temperature, high-speed condition longtime running, do not need the servicing unit such as fuel feeding or control system, elastic foil bearing due to the shaping surface required precision of its bearing top foil higher, the resilience of material is better, its processing method is a very difficult problem always, mainly accurately cannot arrive machining to need to ask, there is the situation that resilience is larger, also not processing the special of top foil of elastic foil gas bearing at present can pressurize cold working mould.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the present invention proposes a kind of for top foil of elastic foil gas bearing can pressurize cold working mould, can solve top foil in the resilience problem of forming process ensures machining accuracy, has the advantages that structure is simple, cost is low.
To achieve these goals, the technical solution used in the present invention is:
A kind of for top foil of elastic foil gas bearing can pressurize cold working mould, comprise discoid patrix 2, patrix 2 is furnished with locating ring 1, locating ring 1 is connected with bolt with patrix 2, the groove fit location of the pressing plate 10 of locating ring 1 and tension machine 8, the lower surface of patrix 2 is provided with semicolumn 3, counterdie 6 is provided with the concave surface coordinated with semicolumn 3, concave surface has one groove for installing top foil 5, pull bar 7 is through the stayed mast 9 of tension machine 8, pressing plate 10, patrix 2 and counterdie 6, pull bar 7 is positioned at below counterdie 6 and is provided with lower nut 12, pull bar 7 is positioned at above pressing plate 10 and is provided with top nut 11, pressing plate 10, patrix 2, counterdie 6 is fixed by top nut 11 and lower nut 12, during use, top foil 5 is snapped in counterdie groove and counterdie 6 inner surface is fitted, top foil 5 is put polyfluortetraethylene plate 4.
Tension machine 8 tightens top nut 11 after pressurizeing, and cuts off hydraulic pressure puller system 8 and the connection of stayed mast 9, utilizes top nut 11 and the pressurize of lower nut 12 pretension, control the dwell time as required.
Because the present invention is only made up of locating ring 1, patrix 2, semicolumn 3, polyfluortetraethylene plate 4 and counterdie 6, have that structure is simple, cost is low, the feature of economize energy.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
See accompanying drawing, a kind of for top foil of elastic foil gas bearing can pressurize cold working mould, comprise discoid patrix 2, patrix 2 is furnished with locating ring 1, locating ring 1 is connected with bolt with patrix 2, the groove fit location of the pressing plate 10 of locating ring 1 and tension machine 8, the lower surface of patrix 2 is provided with semicolumn 3, counterdie 6 is provided with the concave surface coordinated with semicolumn 3, concave surface has one groove for installing top foil 5, pull bar 7 is through the stayed mast 9 of tension machine 8, pressing plate 10, patrix 2 and counterdie 6, pull bar 7 is positioned at below counterdie 6 and is provided with lower nut 12, pull bar 7 is positioned at above pressing plate 10 and is provided with top nut 11, pressing plate 10, patrix 2, counterdie 6 is fixed by top nut 11 and lower nut 12, during use, top foil 5 is snapped in counterdie groove and counterdie 6 inner surface is fitted, top foil 5 is put polyfluortetraethylene plate 4, after the pressurization of tension machine, tighten top nut 11, cut off the connection of hydraulic pressure puller system 8 and stayed mast 9, utilize top nut 11 and the pressurize of lower nut 12 pretension, control the dwell time as required.
Operation principle of the present invention is
During use, semicolumn 3 is pressed in polyfluortetraethylene plate 4, cover patrix 2, locating ring 1 is arranged on patrix 2, and locate with the groove fit of tension machine pressing plate 10, pull bar 7 is tightened through patrix 2 and counterdie 6 and with top nut 11 and lower nut 12 and applies certain preloading, start hydraulic pressure puller system 8, utilize the pulling force of stayed mast 9 that patrix 2 and counterdie 6 are extruded mutually, impel the polyfluortetraethylene plate 4 in semicolumn 3 and counterdie 6 to be out of shape, polyfluortetraethylene plate 4 and counterdie intrados extrude and make top foil 5 shaping.
