Abstract
The invention provides a clamping correction device and a clamping correction method for eliminating an internal stress of a steel structure workpiece with a deformable plate during heating correction. The clamping correction device is provided with an upper clamping surface and a lower clamping surface which are arranged oppositely, and the clamping surfaces are tightly pressed against a correction part to be machined along a length direction of the correction part to be machined. Force is applied to the correction part to be machined and the correction part to be machined is clamped, so the internal stress of the correction part to be machined is eliminated during heating correction; therefore, the amplitude deformation of the correction part to be machined of the workpiece can be avoided during heating correction.
Description
Technical field
The present invention relates to steel construction work piece correcting technical field, be specifically related to a kind of clamping apparatus for correcting and antidote.
Background technology
H shaped steel is in manufacturing process, because the residual stress that the cutting welding produces can cause H shaped steel unstability, web produces wave transformation.The general flame heat of routine that adopts is corrected.But because the flange plate width of H shaped steel is little, and web plate section is big, and steel plate is thinner again, in any case this special construction is placed, web can cause internal stress when flame heat is corrected, and has strengthened the wave amplitude distortion of web on the contrary.The large-scale steel structure workpiece with yielding plate of this similar H type web all this type of problem can occur.
Summary of the invention
Primary and foremost purpose of the present invention provides a kind of clamping apparatus for correcting that can eliminate the internal stress that steel construction workpiece with yielding plate produces when adding heat straightening.
The clamping apparatus for correcting that proposes according to the present invention has the clamping area of two positioned opposite up and down, described clamping area along the length direction of orthopedic portion to be processed closely against orthopedic portion to be processed.
Another object of the present invention provides a kind of antidote that uses above-mentioned clamping apparatus for correcting, may further comprise the steps:
A: by to be processed orthopedic the clamping of clamping area with workpiece, clamping apparatus for correcting applies preliminary clamping force for orthopedic portion to be processed, then in the both sides of the clamping area that clamps apparatus for correcting, the to be processed orthopedic portion of workpiece is tentatively added heat straightening along the length direction of workpiece;
B: remove the clamping force that clamps apparatus for correcting, the to be processed orthopedic portion of workpiece is detected, determine the deformed region of orthopedic portion to be processed;
C: clamp apparatus for correcting and apply clamping force once more, further add heat straightening at the deformed region of orthopedic portion to be processed.
The present invention clamps by the application of force to orthopedic portion to be processed, has eliminated the internal stress that orthopedic portion to be processed produces when adding heat straightening, thereby can avoid the to be processed orthopedic portion of workpiece to produce the wave amplitude distortion when adding heat straightening.
Description of drawings
Fig. 1 is a user mode structural representation of the present invention.
The specific embodiment
As Fig. 1, primary and foremost purpose of the present invention provides a kind of clamping apparatus for correcting 1, this clamping apparatus for correcting 1 has the clamping area 11 and 12 of two positioned opposite up and down, and described clamping area 11 and 12 is implemented clamping along to be processed orthopedic 20 both forward and reverse directions treating orthopedic workpiece.By the application of force to be processed orthopedic 20 is clamped, eliminated orthopedic 20 internal stress that when adding heat straightening, produces to be processed, thereby can avoid to be processed orthopedic 20 of workpiece when adding heat straightening, to produce the wave amplitude distortion.
Described clamping apparatus for correcting 1 comprises up and down two hollow clamping square columns 110 and 120, and described clamping area 11 and 12 is respectively up and down two and clamps square column 110 two end faces relative with 120, and described square column 120 belows that clamp down are provided with adjustable for height brace table 3.So just can utilize the height of the adjusting clamping apparatus for correcting 1 of brace table 3, to adapt to the different orthopedic workpiece for the treatment of.
Described clamping square column 110 tops of going up also are provided with crossbeam 4, and described going up is provided with jack 5 supports between clamping square column 110 and the crossbeam.Utilize the support force of jack, the clamping force of clamping area 11 in the assurance is guaranteed stability to be processed orthopedic 20.
Another object of the present invention provides a kind of antidote that uses above-mentioned clamping apparatus for correcting, may further comprise the steps:
A: by clamping area 11 and 12 to be processed orthopedic 20 clampings with workpiece, clamping apparatus for correcting 1 applies preliminary clamping force for orthopedic portion to be processed, then in clamping area 11 that clamps apparatus for correcting 1 and 12 both sides, the dashed region among Fig. 1 just tentatively adds heat straightening along the length direction of workpiece to the to be processed orthopedic portion of workpiece;
B: remove the clamping force that clamps apparatus for correcting 1, to be processed orthopedic 20 of workpiece detected, determine deformed region to be processed orthopedic 20;
C: clamp apparatus for correcting 1 and apply clamping force once more, further add heat straightening at deformed region to be processed orthopedic 20.
Claims (4)
