Storage sphere inner wall radius is consistent,
When work, fixing mould is fixed on spinning machine main shaft, and inner cavity is towards spinning tail top, positioning tool evagination curved end
Towards spinning machine main shaft, the other end is fixed on spinning tail top, and the center line of positioning tool is overlapped with spinning machine spindle centerline.
Based on the storage sphere manufacturing method of the above-mentioned device for storage sphere manufacture, include the following steps:
Step 1 makes spinning blank, chooses the plate-shape metal with storage sphere wall same thickness, using punching press or stretches work
Plate-shape metal is processed into the spinning blank that bottom surface evagination is in hemispherical tubbiness, hemisphere face outer diameter and storage sphere outer diameter one by skill
It causes；
Step 2 installs fixing mould and positioning tool, installs fixing mould respectively on the main shaft of spinning machine and tail top and determines
Position tooling；
Spinning blank bottom is fitted in the inner cavity of fixing mould, the opening direction rotation of spinning blank by step 3, fixed spinning blank
Press tail top, spinning tail pushing tow move the inside of positioning tool insertion spinning blank until bottom wall, and it is fixed that spinning blank is pressed on
The inner cavity of position tooling；
S1: spinning blank open end is heated to 1000-1150 DEG C, and in subsequent forming process by step 4, mould pressing
Continue concurrent heating to keep temperature；S2: the open end outer wall of the spinning roller of mobile spinning machine to spinning blank passes through main shaft and spinning roller
Rotation carries out necking in processing to the sealing part of spinning blank, and spinning roller is fed to positioning tool center line, and executes semicircle
Track keeps spinning blank open end slowly close to positioning tool；S3: spinning blank opening port inner wall Distance positioning tooling
When 5-10mm, positioning tool is extracted out, continues to carry out necking in spinning blank, until the end socket of semielliptical shape is obtained, S4:
Spinning roller continues to carry out finishing spinning to end socket surface using axially and radially resultant movement of feed, until ellipse by the half of spinning blank
Spherical part is spun into hemispherical dome structure.
Further, in step 4, spinning machine main shaft is with the rotation speed operation of 200~300rpm.
The storage sphere manufacturing method and its device that the technical program provides, can be by one piece of thin-wall boards by being spun into
Shape is processed into storage sphere entirety, solves the problems, such as that there are weld seams using hemisphere welding manner in the manufacture of traditional spheroidal gas cylinder, originally
The pressure-bearing of the storage sphere of case method manufacture is stronger, the method for thin-wall boards rotary press modelling, and in the prior art by one
The process that thick blank forging or extruding finally produce storage sphere is compared, and is improved the utilization rate of material, is reduced manufacture
Cost, this kind of manufacturing method are monolithic molding, and no-welding-seam, container use reliability is high, and the manufacturing cycle is short, and manufacturing cost is low.
