Figure 29 is efficient oxy-acetylene arbor press and corrects moulding bed and correct especially big plate system BH member.(the wing plate Welding Angular Deformation is corrected instance graph)

Figure 30 is efficient oxy-acetylene arbor press and corrects moulding bed and correct especially big plate system BH member.(the web Welding Angular Deformation is corrected instance graph)

The example explanation;

1. among Figure 29 the member wing plate is held on L type correction bracket (1) and goes up on the channel-section steel supporting base (5) on channel-section steel supporting base (6) and the traversing carriage (2), simultaneously efficient oxy-acetylene arbor press is positioned on the roomy wing plate, will spray the reverse side that torch is positioned at weld seam.(the wing plate Welding Angular Deformation is corrected example)

2. among Figure 30 the member wing plate is held on the channel-section steel supporting base (5) on L type correction bracket (1) upper limit supporting base (7) and the traversing carriage (2), simultaneously efficient oxy-acetylene arbor press is positioned at the downside that places web, will the spray torch be positioned at the reverse side of weld seam.(rectification of web Welding Angular Deformation)

3. according to the weld seam feature of plate system H shaped steel, its angle welding welding process is a wire heating process, with weldering welding automatically, welding deformation angle basically identical.Therefore, this machine is placed the reverse side of deformation of member direction, do moving back and forth of infeed stroke 300mm with the transfer arm that 10 sprays of row torch device is housed and heat straightening members, member heating is had heat concentrate and be wire uniform heat distribution, the high characteristics of efficient, demonstrate fully this machine and correct feature efficiently.Therefore, the member corrected zone is under high temperature, moment and gravity effect, thereby strength and stiffness reduce the contraction of having accelerated the member heating surface, reach the rectification purpose.

4. among the figure, correcting the strong middle channel-section steel supporting base of moulding bed has two effects;

A. play the safeguard protection effect.Before rectification, after member left side wing plate was compressed by lifting pressing plate (3) and L type correction bracket, right side wing plate web was in vacant state, as does not have support to be had unstability by straightening members.

B. play position-limiting action.Member is under action of high temperature, and deadweight produces downwarp, but the amount of downwarp must be controlled.The precision that has had the easier assurance member of channel-section steel supporting base to correct.

5. electric device control is required is stroke distances, travel speed, the gas flow to transfer arm, the control of gas pressure to this tool.
