Abstract
The invention discloses a large-diameter cylinder rounding tool, which comprises three independent sub cylinders formed by cutting a cylinder in the axial direction, wherein every two of the three sub cylinders are adjacent and encircled to the center, one sub cylinder is mutually hinged with the other two adjacent sub cylinders, the adjacent positions of the two sub cylinders are not connected, a pair of wedge blocks is fixedly arranged at the upper end and the lower end of the adjacent positions of the two non-connected sub cylinders respectively, and a wedge port is formed between each pair of wedge blocks. The large-diameter cylinder rounding tool is simple in structure and convenient for operation; the cylinder to be machined meets the requirement of high roundness without machining, so that the machining cost is greatly reduced, and the machining period is shortened; and the tool can be reused. The tool is suitable for rounding machining of the large-diameter cylinders of all medium thin plates with high roundness requirements.
Description
Technical field
The present invention relates to large-diameter cylinder body and hold round device, be specifically related to large-diameter cylinder body and hold round frock.
Background technology
Cylindrical shell is a modal member in the chemical industry equipment, and large-diameter cylinder body generally rolls welding by metallic plate and forms, and its circularity is to be processed to form through the Artificial Control veneer reeling machine, and workman's operative skill directly influences the deviation size of cylindrical shell shaping circularity.In actual production process, the cylinder roundness deviation is inevitable, but in some specific chemical industry equipments, requires very high to cylinder roundness.At present normally through increasing barrel thickness, and then the drum surface that rolls after the welding carried out the high circularity that machined realizes cylindrical shell.But along with the continuous development and update of chemical equipment, the special material that price is more expensive and the utilization of difficult-to-machine material are more and more, like stainless steel, titanium, nickel, composite board etc.; The cylindrical shell wall thickness made from special material is also thinner; Rigidity is relatively poor, so cylindrical shell machined difficulty is big, quality is difficult to guarantee simultaneously; Carry out mach words again if select for use the thicker special material of thickness to process cylindrical shell, will increase material deterioration inside and production cost.
Summary of the invention
The problem that the present invention need solve provide a kind of cost low, need not machined and can reach the large-diameter cylinder body that high circularity requires and hold round frock.
For addressing the above problem; The technical scheme that the present invention adopts is: large-diameter cylinder body holds round frock, comprises that a cylinder cuts apart three that the back forms vertically and independently divide cylindrical shell, and three branch cylindrical shells are adjacent in twos entad to surround; One of them divides between cylindrical shell and the adjacent two fens cylindrical shells and is hinged; The adjacent of two branch cylindrical shells does not have connection in addition, and the top and bottom of connectionless two minutes cylindrical shell adjacents are set with a pair of voussoir respectively, forms the wedge mouth between every pair of voussoir.
Further; Aforesaid large-diameter cylinder body holds round frock; Wherein, Along the circumferential direction be provided with four circle support rings on the inwall of described three branch cylindrical shells respectively, described every circle support ring lays respectively at the equal-height position of three branch cylindrical shells, is provided with stiffener between two ends of the support ring on described each branch cylindrical shell.
Further, aforesaid large-diameter cylinder body holds round frock, and wherein, the top of described each branch cylindrical shell is provided with hanger.
Advantage of the present invention is: simple in structure, easy to operate, and do not need machined can make the required cylindrical shell that holds round processing reach the requirement of high circularity, greatly reduce processing cost, shortened the process-cycle, and can reuse.
Description of drawings
Fig. 1 is the plan structure sketch map that large-diameter cylinder body of the present invention holds round frock.
Fig. 2 is an A-A cross-sectional view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
Like Fig. 1, shown in Figure 2; Large-diameter cylinder body holds round frock, comprises that a cylinder evenly cuts apart three that the back forms vertically and independently divide cylindrical shell, is respectively: first fen cylindrical shell 1, second fen cylindrical shell 2, the 3rd fen cylindrical shell 3; Three branch cylindrical shells are adjacent in twos entad to surround; Along the circumferential direction be provided with four circle support rings 4 on the inwall of three branch cylindrical shells respectively, described every circle support ring 4 lays respectively at the equal-height position of three branch cylindrical shells, as shown in Figure 2; Support ring 4 is evenly distributed on each minute cylindrical shell, between two ends of the support ring 4 on described each branch cylindrical shell, is provided with stiffener 5; Hinged mutually between first fen cylindrical shell 1 and adjacent second minute cylindrical shell 2 and the 3rd fen cylindrical shell 3; As shown in Figure 2; Articulated manner can be for respectively welding a location connecting plate 8 on two fens adjacent cylindrical shells; Two are located by connecting is hinged between the plate 8, and pin joint can evenly be provided with along a minute cylindrical shell height, is provided with two pin joints in the present embodiment in the top and bottom of minute cylindrical shell; Do not have between second fen cylindrical shell 2 and the 3rd fen cylindrical shell 3 are adjacent and connect, the top and bottom of second fen cylindrical shell 2 and the 3rd fen cylindrical shell 3 adjacents are set with a pair of voussoir 61 respectively, wedge mouth 6 of formation between every pair of voussoir 61.A hanger 7 is arranged at the top of described each branch cylindrical shell.The cylindrical of the described cylinder that is made up of three branch cylindrical shells guarantees that through machined the circularity of cylindrical meets the demands.
When holding round;, wraps large-diameter cylinder body earlier the separation layer of one deck suitable thickness on holding round the outer wall of frock; Again large-diameter cylinder body being held round frock advances to need in the cylindrical shell of processing through hanger 7 liftings; Need the barrel diameter of processing to hold round the big 1 ~ 2mm of frock than large-diameter cylinder body usually, squeeze in the wedge mouth 6 with two chocks 9 that adapt with wedge mouth 6 then, large-diameter cylinder body holds round frock and constantly expands at this moment; Cylindrical shell 1 constantly outwards opened with adjacent second minute cylindrical shell 2 and the 3rd fen cylindrical shell 3 in promptly first minute; Need simultaneously in this course not knock the position that holds round the frock applying, thereby finally make the cylindrical shell and the frock cylindrical shell that need hold round processing fit fully, reached the purpose that holds round with large-diameter cylinder body with wooden mallet.Cylindrical shell after holding round can not be pulled down from frock at once, need make it with other required parts welding back and hold round frock with large-diameter cylinder body and carry out the stress-removal heat treatment that adapts with cylinder material, can pull down frock after stable shaped.
The present invention is simple in structure, and is easy to operate, do not need machined can make the required cylindrical shell that holds round processing reach the requirement of high circularity, greatly reduces processing cost, shortened the process-cycle, and can reuse.The present invention is applicable to the processing that holds round of large-diameter cylinder body that the high circularity of thin plate in all requires.
