Abstract
The invention discloses an expansion device of an expansion rod, which belongs to the technical field of pressure vessel processing or treatment. The expansion device of the expansion rod consists of an expansion inner ring, an expansion outer ring, a plurality of expansion rods and a U-shaped slotted plate, wherein a plurality of threaded holes are uniformly distributed on the circumferential face of the expansion inner ring; the threaded end of each expansion rod is connected with one of the threaded holes of the expansion inner ring, and one end with a step of each of the expansion rods is rotationally connected with a hole at the bottom of the U-shaped slotted plate; and the expansion outer ring consists of a plurality of segments and the inner circumferential face of each segment of the expansion outer ring is fixedly connected with the top of the U-shaped slotted plate correspondingly and respectively. The expansion device of the expansion rod of the invention has the advantages of simple structure, convenient dismantling, practicability, effectiveness and low making cost. When the expansion device of the expansion rod is used, the welding deformation of a vessel can be reduced or eliminated.
Description
Skill wood field
The invention belongs to the processing technique field of pressure vessel, relate to a kind of device that dilates of container manufacturing, be specifically related to a kind of device that dilates of expansion link.
Technical background
Pressure vessel is a kind of bearing device that is used widely in nearly all industrial production and daily life.Pressure vessel is in manufacture process, because the influence of various factors may produce hidden danger of quality miscellaneous, thereby influence the safe handling of pressure vessel, stainless steel pressure container particularly, service condition more complicated, its medium is special, as inflammable, poisonous, corrosion etc.; And explosion danger is arranged.In case have an accident, then its consequence is catastrophic, brings massive losses can for country, enterprise, individual lives and properties.Therefore, the workmanship of guaranteeing the stainless steel pressure container will be very important.But the stainless steel pressure container is because the heat transfer coefficient of its stainless-steel sheet is less, and thermal coefficient of expansion is bigger, and welding after-contraction amount is also bigger, adds stainless welding characteristic, is easy to cause occur in the manufacture process hidden danger of quality problems such as welding deformation.In order to reduce or to eliminate this phenomenon of welding deformation, dilate device in the inner employing of pressure vessel weld joint on inner side and weld seam both sides are assisted reinforcement, can effectively eliminate the welding stress and the welding deformation of pressure vessel.But also do not have a kind of simple in structurely, easy to loading and unloading at present, practical and effective is used for the device that dilates of pressure vessel.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, easy to loading and unloading in order to satisfy the needs that the stainless steel pressure container is made, the practical and effective expansion link dilate device.
For achieving the above object, technical scheme of the present invention is:
A kind of expansion link dilate device, dilate inner ring by one, dilate the outer ring, some expansion links and U type frid constitute, and are evenly equipped with some tapped through holes on the described periphery that dilates inner ring; The end that described expansion link is provided with screw thread with dilate the inner ring tapped through hole and be connected, the end that described expansion link is provided with step rotatably is connected with the hole that U type frid bottom is provided with; The described outer ring that dilates is made of the plurality of sections arc plate, and the inner headed face of every section arc plate corresponding U type frid top respectively is fixedly connected.
The above dilate the reinforcement that inner ring also is laid with some connection central rings and axially is fan shape.
The expansion link of the above is 6.
The expansion link interlude of the above is a regular polygon.
The outer ring that dilates of the above is made of 6 sections arc plates.
A kind of expansion link of the present invention dilate device, its beneficial effect and major advantage are: simple in structure, easy to loading and unloading, practicability and effectiveness, low cost of manufacture.Use the device that dilates of this expansion link, can effectively reduce or eliminate the welding deformation of stainless steel pressure container.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 cutaway view;
Among the figure: 1. dilate inner ring, 2. expansion link, 3.U type frid, 4. nut 5. dilates the outer ring, 6. reinforcement, 7. central ring.
The specific embodiment
Be described further below in conjunction with the device that dilates of accompanying drawing a kind of expansion link of the present invention.
As shown in Figure 1 and Figure 2, a kind of expansion link of the present invention dilate device, dilate inner ring 1 by one, dilate 5,6 expansion links in outer ring and 6 U type frids constitute, uniformly on the described periphery that dilates inner ring 1 offer 6 tapped through holes; One end of described expansion link 2 is provided with screw thread and dilates inner ring 1 tapped through hole and be connected, the other end that described expansion link 2 is provided with step passes the hole that U type frid 3 bottoms are provided with and adopts nut 4 fastening, and guarantees that expansion link 2 rotatably is connected with U type frid 3; The described outer ring 5 that dilates is made of 6 sections arc plates, and the inner headed face of every section arc plate corresponding U type frid 3 tops respectively adopts welding fixedly connected; The described inner ring 1 that dilates also is laid with some connection central rings 7 and axially is fan shape, and quantity is 3 reinforcement 6; The interlude of described expansion link 2 is processed into quadrangle or hexagon, so that tool holding, makes expansion link 2 distaff center positive and reverse returns then realize that axial stretching reaches to dilate inside diameter of vessel and unload the purpose that dilates device.
