Abstract
The utility model relates to a fixture-typed centrifugal mechanism in the technical field of self-propagating high-temperature synthesis abbreviated as SHS, the major device of which is SHS aluminothermy-centrifugal filler. The device of the prior arts imposes strict length of the steel pipe of different diameters. The utility model improves the fixtures of the centrifugal filler, with the internal wedge circle and the external wedge circle wedged as the fixture. The internal wedge circle is two semi-circles or three evenly divided circles and the external wedge circle is a complete circle, wherein the internal wedge circle and the external wedge circle are fixed by the double-ended bolt, which clamp the steel pipe. When the steel pipe is used as the sleeve, the inside is positioned with a small-diameter steel pipe to be coated with metal ceramic, which is supported in the sleeve by the support ring to lengthen the steel pipe. The fixture of the utility model can lengthen the ceramic composite steel pipe, which is particularly applicable to the ceramic composite steel pipe of great caliber in length, and is easy for installation and stable in operation.
Description
Technical field
The utility model is a kind of fixture type centrifuge structure of self propagating high temperature synthetic technology, and this centrifuge structure is mainly used in the preparation of composite steel pipe with cermet lining.
Background technology
Self propagating high temperature synthetic technology (self-propagating high-temperature synthesis, SHS) be to develop very a kind of rapidly New Processing, it can be produced or the moulding traditional handicraft can't be produced super fine ceramics dusty material and composite product thereof over past ten years.Present some SHS aluminothermy-centrifugal casting machines that use, all are nonstandard type tube formula centrifuges of self design, production to the little small-caliber thin-walled tube of large-diameter pipe that radially deflection is big or rigidity, strict restriction is arranged on length, production length generally has only 2-3m, length will make the cermet composite steel tube stuck in type tube slightly, and causes that ceramic layer comes off and ftractures, and has a strong impact on the structural intergrity and the reliability of cermet composite steel tube product.
In the prior art, according to the difference of steel pipe method of clamping, it is clipping clipping with scroll chuck that the present SHS centrifuge that uses can be divided into the type tube structure basically.The type tube structure is clipping, when outer diameter of steel pipes and length variations, and parts such as necessary corresponding change type tube and chuck, operation is extremely inconvenient.Though spring can play the fixing effect, limited thermal expansion displacement axial when steel pipe is heated to a certain extent; In addition, the inconvenience because steel pipe in type tube inside, is lighted a fire.Scroll chuck is clipping, the scroll chuck clamping of steel pipe one end, the other end is supported by clamp bracket, improved and originally had only scroll chuck clamping other end structure freely, even but steel pipe apply pre-installed hold very tight, also easily because the steel pipe radial dimension contraction of reaction back blocks not tight, even fly out, there is the bigger problem of steel pipe free end circular runout, and owing to keep the scroll chuck clamping, finally can not solves steel pipe and expand with heat and contract with cold before and after applying and cause the not tight problem of three-jaw folder; Clamp bracket adopt to raise in addition, the downward modulation screw mandrel is regulated, and the invar pipe is removed stage makeup and costume and clamped ventricle and have error, regulates the screw mandrel inconvenience, inefficiency at every turn.Above-mentioned dual mode is because of structural limitations, only be applicable to production length at 3m with interior short ceramic composite steel pipe, production efficiency is low and have phenomenons such as pottery shelling and cracking.
Summary of the invention
The purpose of this utility model be a kind of simple in structure, steel pipe rotation of design steadily, charge and discharge operations can prepare the fixture type SHS centrifuge structure of long ceramic-lined composite steel tube easily, mainly is clamp structure wherein.
The SHS centrifuge mainly is made up of three parts: centrifuge main frame, steel pipe anchor clamps and igniter.The construction profile of centrifuge main frame and steel pipe anchor clamps is seen Fig. 1～5, be characterized in that the steel pipe clamp member is to be assemblied in outer anchor clamps of steel pipe and end cap composition, anchor clamps are made up of internal wedge ring and outer wedge ring, and internal wedge ring is made up of 2～4 five equilibrium annulus, the axial tapered inclined-plane of the cylindrical of ring.Outer wedge ring is a domain, in it circular shaft to being same tapered slope with internal wedge ring, interior outer wedge ring wedge and the time conical surface opposite, be beneficial to wedging.Fig. 4 right half part is the parts schematic diagram that inside and outside wedge ring separates, and stud is fixed them by passing inside and outside wedge ring, and outer wedge ring one side has a flange, prevents the effect of steel pipe axial float when playing rotation.Stud passes inside and outside wedge ring, and the effect on screwing force and inside and outside wedge ring inclined-plane by bolt is tightened up internal wedge ring inwards, firmly clamps steel pipe; Fig. 4 left-half is the schematic diagram after inside and outside wedge ring closes up assembling, and two ends are loaded onto and can be added thermite behind the end cap and carry out the SHS reaction.
The material of inside and outside wedge ring of the present utility model can be carbon steel, steel alloy and water cast steel.
If with above-mentioned anchor clamps steel pipe as sleeve pipe, the small-caliber steel pipe of metal coated pottery is placed in the sleeve pipe with the support ring support, the quantity of support ring is decided as required, and the assembling mode of the anchor clamps of outer layer sleeve steel pipe is same as described above, and Yi La Zhu positions with fixing between support ring.The nexine steel pipe is loaded onto end cap and is carried out the SHS reaction.The inclined-plane form of the inside and outside wedge ring of never-slip has guaranteed when the decapacitation of assembling rear jig clamps steel pipe, also guaranteed the concentricity of steel pipe and inside and outside wedge ring, outer wedge ring and flywheel cylindrical all pass through the lathe metalworking, the running accuracy height, can easily reach higher rotation speed and Oscillation Amplitude is little, make that wall energy applies very uniform, the high-quality cermet coating of a layer thickness in steel pipe.This kind structure can claim that this is the bushing type anchor clamps, the steel pipe of the big length of very suitable preparation, minor diameter.
The quantity of support ring can be decided according to steel pipe length, generally is advisable with 4-10.
Internal wedge ring then makes operation more convenient if make 2～3 branch rings such as annulus.
One flange is arranged, axial float when preventing the steel pipe rotation on the outer wedge ring.
This fixture type centrifuge structure can be used for preparing composite steel pipe with cermet lining, and its cermet is TiB
