Abstract
The invention discloses a kind of cone coiled forming technology of dome head, the step of the moulding process are as follows: a, selection cutting: select metal plate according to the material and size of wanted molding dome head and cut to obtain circular arc panel and round panel；B, cone rolls: arc surface coiled sheet being made to the hollow frustum of a cone using cone；C, the hollow frustum of a cone punch forming: is struck out to bottomless bowl；D, drum pressure forms: by round panel drum pressure at arc groove；E, the arc groove in the bottomless bowl and step (d) in step (c) is welded together and constitutes a dome head；F, it examines: testing after qualification end socket obtained up to the end socket of required preparation.The present invention makes dome head using the molding mode of cone, and speed of production is 5 times of whole drum pressure technique, two weld seams fewer than partition machining, can guarantee the quality of end socket and reduces the time of welding flaw detection；It is able to maintain smaller reduction and material saving.
Description
Technical field
The present invention relates to seal head molding technical field, specifically one kind can save material, reduce cost and energy
Enough improve the cone coiled forming technology of the dome head of production efficiency.
Background technique
Dome head forming method is generally divided into: punching press straight forming or partition machining.Due to by equipment etc.
Limitation, to it is some be relatively large in diameter, plate thickness is thicker and it is some without mold can not rotary press modelling dome head etc., need greatly
Type head pressing molding equipment；Partition machining takes time and effort, and since weld seam is more, the quality of end socket can not be effectively ensured.
Summary of the invention
In response to the problems existing in the prior art, the purpose of the present invention is to provide one kind to save material, reduces cost
And it can be improved the cone coiled forming technology of the dome head of production efficiency.
The purpose of the present invention is what is solved by the following technical programs:
A kind of cone coiled forming technology of dome head, it is characterised in that: the moulding process carries out in the steps below:
A, selection is cut: being selected metal plate according to the material and size of wanted molding dome head and is cut to obtain circular arc
Panel and round panel；
B, cone rolls: arc surface coiled sheet being made to the hollow frustum of a cone using cone；
C, the hollow frustum of a cone punch forming: is struck out to bottomless bowl；
D, drum pressure forms: by round panel drum pressure at arc groove；
E, the arc groove in the bottomless bowl and step (d) in step (c) is welded together into composition one spherical envelope
Head；
F, it examines: testing after qualification end socket obtained up to the end socket of required preparation.
Circular arc number of panels in the step (a) are at least one piece.
When dome head in the step (e) welds completion, then need in step (f) to carry out non-destructive testing weld seam.
The non-destructive testing refers to that carrying out 100%RT detection to weld seam complies with JB/T4730.2-2005 standard.
Steel plate in the step (a) uses carbon steel steel plate.
The present invention has the following advantages compared with prior art:
Dome head of the invention is made of the molding mode of cone, is able to maintain smaller subtract than stamping forming end socket
Thin rate, also compares material saving；It can be improved production efficiency with the production method ratio of partition machining, speed of production is whole drum pressure work
5 times of skill, and two weld seams fewer than partition machining, can effectively guarantee the quality of end socket and reduce welding flaw detection when
Between.

Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and embodiments.
As shown in the figure: a kind of cone coiled forming technology of dome head, the moulding process carry out in the steps below:
A, selection is cut: selecting carbon steel steel plate and cut to be justified according to the material and size of wanted molding dome head
Cambered plate and round panel, wherein circular arc number of panels be at least one piece, the quantity of round panel be one piece；
B, cone rolls: arc surface coiled sheet being made to the hollow frustum of a cone using cone；
C, the hollow frustum of a cone punch forming: is struck out to bottomless bowl；
D, drum pressure forms: by round panel drum pressure at arc groove；
E, the arc groove in the bottomless bowl and step (d) in step (c) is welded together into composition one spherical envelope
Head；
F, it examines: weld seam is carried out non-destructive testing, non-destructive testing refers to that carrying out 100%RT detection to weld seam complies with JB/
T4730.2-2005 standard, after the assay was approved up to the end socket of required preparation.
Embodiment
Carbon steel steel plate and being cut is selected to obtain two pieces of circular arc panels as shown in Figure 1 and one piece as shown in Figure 4 first
Round panel；Using cone the hollow frustum of a cone shown in Fig. 2 is made in arc surface coiled sheet by two pieces of circular arc panels；And it will be hollow
The frustum of a cone strike out bottomless bowl shown in Fig. 3；Round panel drum pressure shown in Fig. 4 is recessed at circular arc shown in fig. 5
Slot；Bottomless bowl shown in Fig. 3 and arc groove shown in fig. 5 are welded together and constitute a spherical shape shown in fig. 6
End socket；Weld seam is carried out non-destructive testing, non-destructive testing refers to that carrying out 100%RT detection to weld seam complies with JB/T4730.2-
2005 standards, after the assay was approved up to the end socket of required preparation.
Dome head of the invention is made of the molding mode of cone, is able to maintain than stamping forming end socket smaller
Reduction, also compare material saving；It can be improved production efficiency with the production method ratio of partition machining, speed of production is whole pressure
5 times of drum technique, and two weld seams fewer than partition machining can effectively guarantee the quality of end socket and reduce welding flaw detection
Time.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within；The technology that the present invention is not directed to can be realized by the prior art.
