Description
Technical field
The present invention relates to the welding fabrication Rapid tooling for a kind of nuclear power plant containment shell Leak-tight liner burst and postwelding to rectify
The fixture of shape one.
Background technology
Nuclear power station Leak-tight liner burst is the important component of containment cylinder, and containment cylinder is by up to a hundred pieces of Leak-tight liners point
Piece is welded, and is molded in shop-fabricated, and the corresponding site for being then lifted into containment cylinder is welded, to dimensional accuracy
It is it is required that higher.However, the big radian of monolithic burst area is small, processing method is first to enter the wall panel structure of burst with bender at present
Row bending, the angle bar needed for wallboard outside is manually then subjected to spot welding, postwelding welds all weld seams again.After welding, to entirety
Plate carries out machinery and flame straightening.But after bender is to wallboard bending machining, wallboard radian produces resilience, after angle bar welding,
The additional stress that welded bands are come so that burst deformation is more serious.It is orthopedic after bending early stage and welding of bender, it is cumbersome
And precision is not easy to ensure, so as to which the processing to Leak-tight liner burst brings puzzlement.Therefore one kind is needed to reach welding fabrication
Rapid tooling and the orthopedic integral fixture of postwelding.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned the shortcomings of the prior art, and provide a kind of structure letter
Burst shaping jig in the containment steel liner that single, easy to operate wallboard radian is quickly quickly corrected after adjustment and burst weld.
In order to solve the above technical problems, the present invention is to be achieved through the following technical solutions：
Burst shaping jig in a kind of containment steel liner, including main bracing frame and used on the main bracing frame
In the chuck structure of clamping burst, it is characterised in that：Along the main bracing frame vertical direction on the main bracing frame
At least one reciprocating sliding block being connected with driver is provided with different height, swing is connected with the sliding block
Support frame, the chuck structure is connected in the other end of the swinging supporter.
Leading truck is provided with the middle part of the main bracing frame, what the sliding block slided sets on the leading truck.
The leading truck includes two parallel leads, and the sliding block is arranged on the lead.
A chuck structure, the swinging supporter being connected on the sliding block are provided with the upper end of the lead
For two.
Scale is provided with the main bracing frame, the pointer to match with the scale is provided with the sliding block.
The chuck structure includes active chuck and separate type chuck, the first end hinge of active chuck and Separated clamping
Connect, the active chuck is connected on the swinging supporter or main bracing frame.
Connected between the active chuck and the swinging supporter or main bracing frame using fastening bolt.
The bolt for burst installation is additionally provided with the swinging supporter or main bracing frame.
The driver is hydraulic cylinder or manual adjusting screw rod.
Shaping jig of the present invention, the wallboard of the Leak-tight liner burst after bending is first lifted into burst shaping jig main body branch
The top of support, adjust the height of driver hydraulic cylinder so that the active chuck that swinging supporter drives contacts with burst, activity
There is chamfering setting chuck both sides, and the gap of active chuck is more than the width of Leak-tight liner wallboard, under the correcting on chamfering inclined-plane, steel
Lining wallboard slips into the gap of active chuck and contacted, and the guide hole on the guide rod and active chuck on separate type chuck is matched somebody with somebody
Insertion is closed, now screws bolt so that the rear side of Leak-tight liner wallboard and the bottom of active chuck are in close contact, burst
Front side is in close contact with bolt, then screws fastening bolt, completes positioning of the burst on fixture, now pointer exists record
The reading of scale.Horizontal angle bar and solebar angle are now distinguished into tack-weld on interior lining panel burst, then will according to technique
Ask, all weld seams are welded.
After the completion of welding, cylinder pressure is slowly discharged, Leak-tight liner burst carries out resilience in the presence of stress.Resilience makes
Swinging supporter band movable slider move up, secondary record pointer scale reading.After Leak-tight liner burst completes resilience,
It is pressurized to hydraulic cylinder, hydraulic cylinder push rod promotes sliding block to move down, and drives the pointer being connected with sliding block to move down, and is moved down by scale record
Scale, then discharge cylinder pressure, Leak-tight liner burst carries out second of resilience, repeatedly more than regulation release cylinder pressure and
Blower operations, finally cause pointer after the scale of scale reaches master scale value, show that the above operates and cause Leak-tight liner burst
Curvature meet needs, complete orthopedic.
Burst wallboard in containment steel liner is lifted into clamping fixture head position by the present invention using tower crane, and regulation hydraulic cylinder is high
Degree so that active chuck is contacted with burst, and the bar that falls on separate type chuck is coordinated into insertion with the guide pin bushing on travel(l)ing rest.Positioning
Bolt is screwed, and the rear side of burst wallboard and the bottom of active chuck are in close contact, and front side and the bolt of burst are in close contact,
Fastening bolt is screwed, completes positioning of the burst wallboard on fixture.Now horizontal angle bar and solebar angle tack-weld is in burst
On wallboard, all weld seams are welded.After the completion of welding, re-adjustments release cylinder pressure and blower operations, finally make
Pointer is obtained after the scale of scale reaches master scale value, is completed orthopedic.The present invention carries out quick-clamping to the wallboard after bending,
Wallboard radian is conveniently adjusted, and is easy to the spot welding of angle bar on the outside of wallboard to position, and Leak-tight liner burst postwelding is convenient by hydraulic means
Correction.Clamping time and the improvement time of angle bar postwelding are greatlyd save, reduces labor intensity, improves orthopedic precision.
