Abstract
The utility model discloses a kind of centrifugal founding and prepare the clamping flange apparatus that bimetallic tubular blank is used, comprise flange body and asbestos board, the heavy chamber that has centre bore on flange body and be communicated with centre bore, the bottom in heavy chamber is provided with some bolt holes, described asbestos board is positioned at heavy chamber, asbestos board has central row pore, and central row pore is communicated with the centre bore of flange body, and asbestos board is fixed by the bottom surface in the heavy chamber of binding agent and flange body.The utility model is simple in structure, long service life, can avoid producing and causing scrapping compared with large residual stress and the obstructed generation gas hole defect of exhaust because the distortion of clamping flange apparatus causes the inaccurate copper alloy layer bias producing in bimetallic tubular blank center, foundry goods, save clamping flange apparatus and change time and materials expense.
Description
Technical field
The utility model relates to a kind of fixture, and especially centrifugal founding is prepared the clamping flange apparatus that bimetallic tubular blank is used.
Background technology
The centrifugal founding of eddy-current heating-particle is that the alloying pellet of prefabricated qualified composition is packed in box hat, be placed in intermediate frequency inductor and rotate around axle center, the electric current of input intermediate frequency inductor produces powerful surface eddy and successively penetrates box hat nexine on box hat, make the box hat melted alloy particle that heats up rapidly, the centrifugal force that rotation produces is evenly built-up in aluminium alloy on box hat inner surface, make non-metallic inclusion and metal oxide isolate alloy body simultaneously, heating is carried out the cooling aluminium alloy that makes fast after stopping and being freezed solidly in steel matrix, produce good metallurgical binding completely in the extremely short time, thereby the thin-wall tube-shaped blank of the bimetallic that obtains function admirable.
The thin-wall tube-shaped blank of bimetallic generally need adopt clamping flange apparatus to be enclosed within tubular blank two ends and to coordinate, be convenient to rotate around axis of rotation by External Force Acting, in heating process, clamping flange apparatus is partly or entirely placed in intermediate frequency inductor, in batch production, need bearing the state of cyclic operation condition of heating-cooling-heating, as not passing a test, quality will produce at short notice fatigue crack, after its distortion, will cause bimetallic tubular blank center inaccurate, and then impel copper alloy layer bias and foundry goods to produce and scrap compared with large residual stress.Have not yet to see centrifugal founding and prepare the concrete report of bimetallic tubular hair slope with clamping flange apparatus, and directly use after the forging process customizing on the former employing of my company market, result of use is bad, also often run into copper alloy liquid and throw away and stick on clamping device, affect to a great extent the dimensional accuracy of bimetallic tubular blank.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, the clamping flange apparatus of long service life.
In order to achieve the above object, the technical solution of the utility model is: a kind of clamping flange apparatus, comprise flange body and asbestos board, the heavy chamber that has centre bore on flange body and be communicated with centre bore, the bottom in heavy chamber is provided with some bolt holes, and described asbestos board is positioned at heavy chamber, and asbestos board has central row pore, central row pore is communicated with the centre bore of flange body, and asbestos board is fixed by the bottom surface in the heavy chamber of binding agent and flange body.
Described bolt hole is two or more.
Diameter >=the 8mm of the central row pore of described asbestos board.
Thickness >=the 2mm of described asbestos board.
Adopt after said structure, the utility model compared with prior art, simple in structure, long service life, avoid in the short time, occurring fatigue crack under the state of cyclic operation condition of heating-cooling-heating, avoid producing and causing scrapping compared with large residual stress and the obstructed generation gas hole defect of exhaust because the distortion of clamping flange apparatus causes the inaccurate copper alloy layer bias producing in bimetallic tubular blank center, foundry goods, saved clamping flange apparatus and changed time and materials expense.
Brief description of the drawings
The embodiment providing below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the structural representation of clamping flange apparatus of the present utility model;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, a kind of clamping flange apparatus, comprise flange body 1 and asbestos board 2, the heavy chamber 7 that has centre bore 6 on flange body 1 and be communicated with centre bore 6, the bottom in heavy chamber 7 is provided with some bolt holes 5, and described asbestos board 2 is positioned at heavy chamber 7, and asbestos board 2 has central row pore 4, central row pore 4 is communicated with the centre bore 6 of flange body 1, and asbestos board 2 is fixed by binding agent 3 and the bottom surface in the heavy chamber 7 of flange body 1.
As shown in Figure 1, 2, described bolt hole 5 is two or more.
As shown in Figure 1, the diameter >=8mm of the central row pore 4 of described asbestos board 2.
As shown in Figure 1, the thickness >=2mm of described asbestos board 2.
Described central row pore 4 and centre bore 6 are convenient to exhaust to reduce the generation of Casting Blowholes, methylcellulose in described binding agent 3 and the allotment volume ratio of water are 1:3～10, more few better after concrete coated weight can better stick on flange body 1 with asbestos board 2, should not occur that asbestos board 2 sticks to flange body 1 time, asbestos board 2 avris have binding agent 3 effusion phenomenons.
