Description
Technical field
The present invention relates to a kind of welding tooling, compression of the sunk type with medicine medicine cavity sealing cover swashs in more particularly to a kind of cylindrantherae
Photocoagulation tooling and compression method for laser welding.
Background technology
Explosive valve is the key equipment of nuclear power technology, and basic functional principle is：By signal source remote control, medicine is lighted
Black powder in cylinder, generates high temperature and high pressure gas, and gas output acting breaks explosive valve stress bolt, pushes explosion valve piston, make
It accelerates to certain speed, cuts off cooling system blind pipe, cooling agent is imported, and is to be used for cooling down reaction under nuclear power plant accident operating mode
Heap, the key equipment for preventing nuclear proliferation.Cylindrantherae is the core component of explosive valve, it will be in the high temperature of reactor, high humidity, core spoke
It is stored for a long time under the adverse circumstances penetrated and internal gunpowder cannot be made to go bad.It is high to the slip requirement of cylindrantherae in this system,
Laser welding must be used during manufacture in the case of powder charge, the requirement of leakage rate could be met.With traditional welding technique
Major advantage compared to laser welding has：Speed of welding is fast, small, the solderable refractory material of deformation, dissimilar material, power density
Height, welding seam deep width ratio are big, can carry out miniature welding, solderable inaccessible position, can carry out non-contact remote welding.
In welded powder canister inner sealing disk, solder joint cannot be guaranteed using traditional tooling and gunpowder in cylinder is reliable and secure is isolated, and due to
Inner sealing disc thickness is only 0.2 millimeter, is easily deformed in pinpoint welding procedure, and when welding needs to set inner sealing disk
Levelling hold-down mechanism has that laser welding gun is interfered with each other with levelling hold-down mechanism.The prior art has to close at the top of cylindrantherae
The technology welded is covered, which is also to generate to overlap with the inner cavity of powder charge around the solder joint not allowed during welding, to prevent
Ignition charge carrys out designing scheme, and the program is object of reference when being welded by setting to control solder joint, such as
2016109960853 it is entitled " with medicine cartridge seal disc spot welding it is levelling from compression tooling and spot welding method " patent Shen
Please, exactly by the way that the clearance gap formed between sealing cover and sealing cover embedded hole to be used as to the object of reference of solder joint, to control solder joint
Position, but this control method does not overcome the factor of human negligence, and also there are the hidden danger of ignition charge.Due to laser welding gun
Welding job could be carried out by needing certain operating space in welding, and sunk type is with the to be welded close of medicine medicine cavity in cylindrantherae
The thickness of capping is only 0.2 millimeter, is easy to deform in pinpoint welding procedure, and when welding must be provided with looking for for inner sealing lid
Flat hold-down mechanism, could carry out the spot welding successively along whole circumference, and sunk type is arranged on deeper in cylinder with medicine medicine cavity in cylindrantherae
Position has that laser welding gun is interfered with levelling hold-down mechanism, in addition, sunk type band medicine medicine cavity sealing cover is installation
In the sealing cover stepped hole of a sinking in cylinder on step, in order to play the role of levelling compression, it is desirable that hold-down mechanism
Outer circle it is substantially identical with the diameter of sealing cover, compacting machine building block is very heavy, when placing it on very thin sealing cover, easily makes
The phenomenon that being displaced into the sealing cover having had good positioning, how after the completion of compression, easily observation detects the positioning feelings of sealing cover
Condition is an important link before spot welding work carries out.
Invention content
