Description
Technical field
This utility model relates to container manufacture technology field, is specifically related to a kind of device making the outer semicanal of pressure vessel ellipse head.
Background technology
Pressure vessel head semicanal was made in the past and usually first seamless steel pipe was curved annulus, then joining line, last gas cutting or plasma cutting according to annulus physical location on end socket is real. But second half cutting down will be unable to be continuing with, cause bigger waste of material. Especially non-ferrous metal, will result in very big cost waste.
Additionally, because the cutting of end socket semicanal is typically all hand cutting, its cut quality is highly unstable. Manual polishing deoxidation slag etc. is needed after well cutting, time-consuming. And welding quality below can be affected.
Summary of the invention
For prior art Problems existing, the present invention provides a kind of device making the outer semicanal of pressure vessel ellipse head, initially with the outer semicanal of cylinder semicanal Mold Making, adopt 6 set of molds that the external semicanal of compounding practice is carried out circular arc afterwards to bend, easy to operate simply, reducing material cost of manufacture, group is high to efficiency of assembling, and welding presentation quality is good.
The technical solution of the utility model is: a kind of device making the outer semicanal of pressure vessel ellipse head, including outer semicanal and 6 moulds of employing cylinder semicanal Mold Making; Described mould includes central shaft, is fixed on the circular bottom plate on central shaft and the circular block being positioned in circular bottom plate, and bottom surface and the side breach of described circular block are arc-shaped so that the bottom surface of circular bottom plate opposing circular block is prominent base plate; Told circular bottom plate is divided into convex circular bottom plate and matrix circular bottom plate, the bottom surface portions upper level of the prominent circular block of convex circular bottom plate is higher than the floor height of circular block, the bottom surface portions upper level of the prominent circular block of described matrix circular bottom plate is lower than the floor height of circular block, concave-convex type circular bottom plate must use in pairs, changes the angle of bend of semicanal by changing the concave-convex type circular bottom plate spill degree of depth and convex height;
Described 6 moulds relatively formed between two by concave-convex type circular bottom plate 1 active mould and 2 pairs be fixedly connected on active mould both sides from moving mold, an arch with prominent base plate is formed between the opposite face of every pair of mould, described outer semicanal is interspersed in arch, and dual-side is by prominent backplanes support;
Described 2 pairs of upper and lower surfaces from the relative active mould of moving mold are movable regulates semicanal bending arc radius; 2 central shafts of described active mould are respectively fixedly connected with machine shaft, and opposite direction rotating friction drives outer half pipe to move.
Further, the bottom surface of described circular block and side breach are six/mono-to quadrant arcuation.
Further, the bottom surface of described circular block and side breach are quadrant arcuation. Contact surface is bigger, increasing friction force, improves circular arc and bends efficiency.
Further, the radius that the radius of described circular bottom plate is round less than circular block end face more than the radius of circular block bottom surface circle. Save material, disclosure satisfy that again job demand.
The beneficial effects of the utility model are: initially with the outer semicanal of cylinder semicanal Mold Making, adopt 6 set of molds the external semicanal of compounding practice is carried out circular arc to bend afterwards, easy to operate simply, reduce material cost of manufacture, group is high to efficiency of assembling, and welding presentation quality is good.
Accompanying drawing explanation
Fig. 1 is that entirety of the present utility model bends structural representation;
Fig. 2 is that 2 moulds of the present utility model assemble schematic diagram.
In figure: 1 is mould, axle centered by 2,3 is circular block, and 4 is circular bottom plate, and 5 is outer semicanal.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1, 2, a kind of device making the outer semicanal of pressure vessel ellipse head, including outer semicanal 5 and 6 moulds 1 of employing cylinder semicanal Mold Making; Described mould 1 includes central shaft 2, is fixed on the circular bottom plate 4 on central shaft 2 and the circular block 3 being positioned in circular bottom plate 4, and the bottom surface of described circular block 3 and side breach are quadrant arcuation so that the bottom surface of circular bottom plate opposing circular block is prominent base plate. The radius that the radius of described circular bottom plate 4 is round less than circular block 3 end face more than the radius of circular block 3 bottom surface circle, and circular bottom plate 4 is divided into convex circular bottom plate and matrix circular bottom plate, the bottom surface portions upper level of the prominent circular block of convex circular bottom plate is higher than the floor height of circular block, the bottom surface portions upper level of the prominent circular block of described matrix circular bottom plate is lower than the floor height of circular block, concave-convex type circular bottom plate must use in pairs, changes the angle of bend of semicanal by changing the concave-convex type circular bottom plate spill degree of depth and convex height. Described 6 moulds 1 by concave-convex type circular bottom plate be relatively formed between two 1 active mould and 2 pairs are fixedly connected on active mould both sides from moving mold, an arch with prominent base plate is formed between the opposite face of every pair of mould, described outer semicanal is interspersed in arch, and dual-side is by prominent backplanes support. Described 2 pairs of upper and lower surfaces from the relative active mould of moving mold are movable regulates semicanal bending arc radius; 2 central shafts of described active mould are respectively fixedly connected with machine shaft, and opposite direction rotating friction drives outer half pipe to move.
During work, making with steel band for raw material, concrete grammar is as follows:
1., first with the frock of cylinder half pipe mold, steel coil strip is made semicanal stand-by.
2. according to the semicanal assembling position at end socket place, select the corresponding mould circular bottom plate spill degree of depth and convex height to vary, (as required configuration). By shown in Fig. 1, mould is completed.
3. the semicanal of roll-forming is pressed shown in Fig. 1 loading mould, further according to the size of curved end socket semicanal radius R, adjustment both sides, front and back are from the distance of moving mold, so as to institute bent arc radius R is same.
4. start driven by motor active mould to rotate, carry out bending of end socket semicanal.
This utility model, initially with the outer semicanal of cylinder semicanal Mold Making, adopts 6 set of molds that the external semicanal of compounding practice is carried out circular arc afterwards and bends, and easy to operate simply reduces material cost of manufacture, and group is high to efficiency of assembling, and welding presentation quality is good.
Although this utility model is disclosed above with preferred embodiment, so it is not limited to this utility model. This utility model art has usually intellectual, without departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations. Therefore, protection domain of the present utility model is when being as the criterion depending on those as defined in claim.
