Abstract
A welding deformation control device comprises a support arc plate, lock nuts, support nuts, a support tube and a support screw. The support arc plate is fixedly connected with one end of the support screw. The other end of the support screw is screwed in a lock nut and a support nut and enters into the support tube. The two ends of the support tube are fixed through the support nuts. The lock nuts are arranged on the outer sides of the support nuts. The welding deformation control device is convenient to operate in a welding process, and therefore welding longitudinal deformation and horizontal deformation are effectively reduced, and assembling tolerance requirements of drawings are guaranteed.
Description
Technical field:
The utility model relates to a kind of welding deformation control device.
Background technology:
Austenitic stainless steel large-sized heavy-wall tube diameter is more than 500 millimeters, and wall thickness is more than 50 millimeters, and when carrying fluid media (medium), thick-walled pipe welds set in nozzle after need to opening hole more than 250 millimeters.Do not allowed any leakage during normal operation, and under high-temperature and high-pressure conditions, worked, can be subject to more complicated and harsh alternate stress effect, so under the prerequisite that guarantees various good mechanical properties and serviceability, also should strictly control welding deformation.Austenitic stainless steel, plasticity is better, the rigidity of structure is less, easily produces welding deformation, therefore effectively control welding deformation, especially after perforate to effective control of set in nozzle welding deformation, be the key point of trunk line equipment welding success or failure.
Summary of the invention:
The purpose of this utility model is to improve a kind of welding deformation control device, and it can effectively reduce welding linear deformation and transversely deforming, and crudy is good.
The utility model is to realize like this, a kind of welding deformation control device, comprise supporting arc plate, locking nut, holding nut, stay pipe, studdle, it is characterized in that: studdle one end is fixedly connected with the supporting arc plate, studdle other end precession locking nut and holding nut enter into stay pipe; Described stay pipe two ends are fixed by holding nut, and the holding nut arranged outside has locking nut.
The utility model is easy to operate in welding engineering, has effectively reduced welding linear deformation and transversely deforming, has guaranteed the build-up tolerance requirement of drawing.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model welding schematic diagram.
Among the figure 1, the supporting arc plate, 2, locking nut, 3, holding nut, 4, stay pipe, 5, studdle, 6, set in nozzle, 7, thick-walled pipe, 8, the welding deformation control device, 9, weld seam.
The specific embodiment:
A kind of welding deformation control device, comprise supporting arc plate 1, locking nut 2, holding nut 3, stay pipe 4, studdle 5, it is characterized in that: studdle 5 one ends are fixedly connected with supporting arc plate 1, studdle 5 other end precession locking nut 2 and holding nuts 3, enter into stay pipe 4, described stay pipe 4 two ends are fixing by holding nut 3, and holding nut 3 arranged outside have locking nut 2.During implementation, austenitic stainless steel large-sized heavy-wall tube 7 diameters can reach more than 500 millimeters, architectural characteristic according to set in nozzle 6, adopt welding deformation control device 8 will further strengthen its structural rigidity, pass through adjustment hole lifting studdle 5 in the stay pipe with boosting-rod, thereby drive 1 lifting of supporting arc plate, behind supporting arc plate 1 and set in nozzle 6 internal diameter close contacts, be locked with locking nut 2, make supporting arc plate 1 and set in nozzle 6 internal diameter contact positions all as stress point, thereby make set in nozzle 6 circumferentially stressed even.
