Abstract
The invention discloses a boiler drum end manufacturing technology which includes the processes of calculating of the unfolded size of an end blank, marking of the end, gas cutting, splicing, pressing and forming of the end, marking and machining of the formed end and packaging of the end. Lofting and marking are conducted according to the unfolded size of the end blank, semi-automatic gas cutting is adopted for blanking, the end is formed by pressing a whole steel plate, if splicing is needed, one end is formed by splicing at most two steel plates, blanking is conducted according to a splicing and discharging picture, then secondary marking and blanking are conducted after gas cutting, splicing and proper welding are conducted on the end and the end is inspected to be qualified, and hot punching is used for forming. The surface of the end does not have bulges or an oxide skin and is smooth in surface and free of cracks, the technology is relatively simple, the processes are reasonable, operation is convenient, and the production efficiency is high.
Description
Technical field
The invention belongs to end socket manufacture craft, be specifically related to a kind of Boiler Drum Head manufacture craft.
Background technology
The entirety that boiler-steam dome is made up of shell sections and heads and other parts, because end socket has spherical, oval etc., on its face, the kind of pipe joint is many and the change in location of pore is various, processing, assembling, welding difficulty, use special frock more, and the part that end socket is assembled is more, and quality requirement is high, so the manufacture of end socket is the most complicated.The manufacture method of end socket is a lot, has artificial hammering, drop weight method, explosive forming, spinning process, pressing etc., and conventional pressing is divided into again cold stamping, drop stamping.
Summary of the invention
The object of the invention is to, a kind of Boiler Drum Head manufacture craft is provided, easy to operate.
Boiler Drum Head manufacture craft provided by the invention, technological process comprises:
The calculating of a, Seal head blank development size: select end socket shape, by the good Seal head blank development size of formulae discovery;
B, the line of end socket, gas cutting, splicing: carry out laying-down according to Seal head blank development size, adopt semi-automatic oxygen-acetylene cutting, end socket adopts the compacting of monoblock steel plate to form, if need splicing, an end socket allows to adopt maximum two block plates to be spliced, but spelling meets centre-to-centre spacing end socket center line must not be greater than 0.3d (d is end socket diameter), and avoid manhole and manhole reinforcement covering part, and avoid the angle welding that stiffener is connected with end socket, also the circular arc portion of edges of boards manhole and edges of boards must not be passed through, needs splicing, first by splicing blanking figure blanking, through gas cutting, assembled, weld appropriate, secondary line blanking is carried out after being up to the standards,
C, end socket compressing: adopt hot press-formed;
The line of d, shaping rear head and processing;
The assembling of e, end socket.
Boiler Drum Head manufacture craft provided by the invention, its beneficial effect is, end socket surface is without bulge, oxide skin, and smooth surface, flawless, technique is relatively simple, and operation is reasonable, and easy to operate, production efficiency is high.
Detailed description of the invention
Below in conjunction with an embodiment, Boiler Drum Head manufacture craft provided by the invention is described in detail.
Embodiment
The calculating of a, Seal head blank development size: select end socket shape, by the good Seal head blank development size of formulae discovery;
B, the line of end socket, gas cutting, splicing: carry out laying-down according to Seal head blank development size, adopt semi-automatic oxygen-acetylene cutting, end socket adopts the compacting of monoblock steel plate to form, if need splicing, an end socket allows to adopt maximum two block plates to be spliced, but spelling meets centre-to-centre spacing end socket center line must not be greater than 0.3d (d is end socket diameter), and avoid manhole and manhole reinforcement covering part, and avoid the angle welding that stiffener is connected with end socket, also the circular arc portion of edges of boards manhole and edges of boards must not be passed through, needs splicing, first by splicing blanking figure blanking, through gas cutting, assembled, weld appropriate, secondary line blanking is carried out after being up to the standards,
C, end socket compressing: adopt hot press-formed;
The line of d, shaping rear head and processing;
The assembling of e, end socket.
