Internal edge, the lower mould extend into the middle part of blank and in the center face of lower mould mould center, set at the top of the upper mould
It is equipped with the lift drive mechanism that mould can be driven to be vertically moved up or down.
The rotary drive mechanism that can rotate mould is additionally provided with the top of the upper mould.
The heater positioned at blank both sides is provided between the upper die and lower die.
The lower mould includes hemispherical backform and the support column installed in backform bottom.
The inner surface setting of the upper mould has the cavity of indent, and the projection of evagination is provided with the top of the lower mould, described
The opening that cavity and male cooperation can be formed at the top of blank.
A kind of pressure volume pot production method using above-mentioned pressure volume pot production equipment, comprise the following steps：
A, blank is placed between upper die and lower die around the blank for forming tubular construction and makes base by the roll of steel plate of rectangle vertically
Expect the internal edge of mould in open top face, while lower mould is extend into inside blank；
B, rotary drive mechanism and lift drive mechanism is driven to rotate mould and be vertically moved up or down using between upper die and lower die
Cooperation is extruded blank；
C, in forming process, the rotation of upper mould makes blank by thermal softening, at the same time the top of blank by extrude formed with
The spherical surface that upper die and lower die surfaces externally and internally coordinates；
D, after being molded, the spherical surface center of blank top squeeze shaping directly forms the open top for mounting flange；
E, after blank being formed into the semi-finished product with spherical surface, other one block of blank repetition aforesaid operations is changed and form other one
Block semi-finished product；
F, two pieces of semi-finished product are carried out welding the pressure volume pot for forming finished product.
In the forming process, start heater, blank is heated by the heater positioned at blank both sides.
After above-mentioned pressure volume pot production equipment and production method, by by roll of steel plate around the base for forming tubular construction
Material directly forms the semi-finished product with top sphere, direct shape after two semi-finished product are welded by upper die and lower die extruding
Into the pressure volume pot of finished product, only two parts are formed the pressure volume pot being consequently formed up and down, it is no longer necessary to in tradition two
Individual hemisphere face is welded respectively with cylinder also no longer to be needed to carry out shaping shearing to hemisphere face by other formers, thus
Not only reduce weld seam, and reduce production craft step, its rational moulding technique, make manufactured pressure volume pot
Pressure-resistant performance is very good, and very high resistance to pressure request has also been reached in practical application, has been had good value for applications.
Brief description of the drawings
Fig. 1 is the structural representation of pressure volume pot production equipment in the present invention；
Fig. 2 is the structural representation of pressure volume pot in the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, to the present invention pressure volume pot production equipment and production method make into
One step describes in detail.
As illustrated, the pressure volume pot production equipment of the present invention, including for there is tubular knot of the roll of steel plate around formation
The blank 1 of structure carries out the upper mould 2 of extrusion forming and lower mould 3, and upper mould 2 has and can form the spherical of spherical surface to blank top
Inner surface 4, lower mould 3 have the outer surface 5 coordinated with upper mould inner surface, and the inner surface setting of upper mould 2 has the cavity 9 of indent, under
The top of mould 3 is provided with the projection 10 of evagination, and cavity 9 and projection 10 coordinate the opening 11 that can be formed at the top of blank；Can by Fig. 1
See, lower mould 3 includes hemispherical backform 7 and the support column 8 installed in backform bottom；Blank 1 is placed in below mould vertically
And making the internal edge of mould in its open top face, lower mould 3 is extend into the middle part of blank and in the center face of lower mould in mould
The heart, the top of upper mould 2 are provided with the lift drive mechanism that mould can be driven to be vertically moved up or down；It is direct from there through upper and lower mould extruding
The semi-finished product with top sphere are formed, the pressure volume pot of finished product are directly formed after two semi-finished product are welded, by Fig. 2
It can be seen that formed the pressure volume pot of finished product only have one of the centre side seam 12 that is formed after the synthesis of two halves semi-finished product and
It is wound into the vertical welded seam 13 of cylindrical blank.
Further, the top of described upper mould 2 is additionally provided with the rotary drive mechanism that can rotate mould, thus exists
Upper mould can be driven to rotate by rotary drive mechanism in forming process, so as to be rotated by the high speed of upper mould, high speed rotary friction
Wiping makes blank then be applied the direct crimp formation of pressure to edge by upper mould by thermal softening and attached in upper die and lower die
Spherical structure on outer surface, the heater 6 positioned at blank both sides is provided between upper mould 2 and lower mould 3.
A kind of pressure volume pot production method using above-mentioned pressure volume pot production equipment, comprise the following steps：
