Preferably, pedestal is L-type pedestal.
As shown in Figure 5 and Figure 6, the molding assembly of bottle body is carried out using following steps:
1) be ready to gas cylinder body steel plate Bear-grudge material, liquid gas storage tank end socket steel plate Bear-grudge material, liquid gas storage tank bottom steel plate
Bear-grudge material cuts ready steel plate Bear-grudge material, the program of transverse cuts is carried out including the edge expected steel plate Bear-grudge,
In cutting, so that the edge at the steel plate Bear-grudge material both ends of gas cylinder body is respectively formed section, so that the edge shape of liquid gas storage tank end socket
At section, so that the edge of liquid gas storage tank bottom forms section；
2) the steel plate Bear-grudge of gas cylinder body is expected with cold forming or thermo shaping method on hydraulic press or spinning machine, liquid gas storage tank
Gas cylinder body 29, liquid gas storage tank end socket, bottom of liquefied gas cylinder is made in the steel plate Bear-grudge material of end socket, the steel plate Bear-grudge material of liquid gas storage tank bottom
Portion, during component cans, so that the edge at gas cylinder body both ends is respectively formed first annular spacing block set 24,
Second ring spacing block set, while the edge of liquid gas storage tank end socket being made to form the first slotting ring 25, so that the side of liquid gas storage tank bottom
Edge forms the second slotting ring, and liquid gas storage tank end socket can be made to be inserted into first annular spacing block set by the first slotting ring 25 of edge in this way
In 24, it is inserted into liquid gas storage tank bottom in the second annular stop convex block by the second slotting ring of edge；
3) in gas cylinder body and the junction of liquid gas storage tank end socket and the junction of gas cylinder body and liquid gas storage tank bottom
Welding.
Steel cylinder is welded in weld, since the high temperature of welding makes chemical property herein change, is corroded in acid-base property
Under the contact of medium, the speed of corrosion is significantly larger than elsewhere.And gas cylinder is typically all to load to have corrosivity (sulfur-bearing Jie
Matter) and high pressure medium.If the steel cylinder of a welding is at an elevated temperature, LNG gasifaction, pressure moment is increased
The safety of several times, that welding steel cylinder cannot guarantee.Even if the explosion limit that the pressure of both steel cylinders is above occurs quick-fried
It splits.The explosion pattern of one-time formed steel cylinder is also at body center with linear explosion, but the blow-up point for welding steel cylinder is
In the weld of end socket, even end socket is blown, the damage to personnel as one can imagine.
In welding, on bottle body after lower head stretch forming, upper lower head carries out recrystallization annealing process after stretching immediately；
Solder joint nearby must descaling, iron rust and greasy dirt；Two parts dock the boxing seam welding to be formed to liquefied gas bottle up and down；
It is heat-treated after bottle body welding, Yao Jinhang stress relief annealing.
So using above-mentioned welding step, in cutting, so that the edge at the steel plate Bear-grudge material both ends of gas cylinder body is respectively formed
Section, so that the edge of liquid gas storage tank end socket forms section, so that the edge of liquid gas storage tank bottom forms section, then molding
When, after component cans, using this embedded structure, it can greatly increase various components in the contact of link position
Face, so that junction is more firm, firm.
In step 2, in first annular spacing block set 24, the second annular stop convex block, the first slotting ring 25, the second slotting ring
On along gas cylinder radial punch so that first annular spacing block set 24, the second annular stop convex block downside on form at least 1
A bulge-structure 26.The step of joined this punch forming, as shown in fig. 6, first annular spacing block set 24 and the first slotting ring
When 25 connection, due to the position-limiting action of bulge-structure 26, so that first annular spacing block set and the first slotting ring, the second annular stop
Certain space is formed between convex block and the second slotting ring, in this way when welding, under the action of high fever, welding base metal is melted
Change, can flow, and be sufficient filling in the above space, can greatly increase in steel cylinder welding process so in the above space
The rigidity of junction, effective solution welding steel cylinder is the technical issues of weld is easy explosion.
Optionally, the bulge-structure is dome-type.
Specifically, can be movable connection type between strut 2 and pedestal 14, so that strut 2 can be with rotation；
Specifically, can be movable connection type between strut 2 and rotating bar 5, allow rotating bar 5 around strut 2
Rotation；
Specifically, welding gun 6 and rotating bar 5 are Demountable, user can be dismantled welding gun 6, hand-held to be welded
It connects.
As bulge-structure improved, that first annular spacing block set 24, the second annular stop convex block process are stamped and formed out
26 correspondences are equipped with the first slotting ring 25, the second slotting ring by the groove structure 27 being stamped and formed out, and using the structure, are being welded
When, under the action of high fever, welding rod is easily flowed into after melting in the groove structure of the first slotting ring, the second slotting ring, and such first
When annular stop convex block 24, the second annular stop convex block are cooperatively connected by the bulge-structure 26 and groove structure being stamped and formed out,
A biggish contact surface can be formed therebetween, further enhance the rigidity of junction.
The diameter of the 26 end face cross section of bulge-structure is less than the diameter of 27 end face cross section of groove structure, is convenient in this way
The metallics formed after welding rod melting is sufficient filling with as in groove structure.
