Description
Technical field
The utility model belongs to the apparatus for correcting, particularly H shaped steel flange plate arbor press of correcting the distortion of H shaped steel flange plate.
Background technology
In the steel construction, the use of H shaped steel is very general in modern times." code for acceptance of construction quality of steel structures " GB50205-2001 has concrete regulation to the perpendicularity permissible variation of H shaped steel flange plate and web, and deflection is not more than one of percentage of flange plate width and is not more than 3mm.
In manufacture process, though taked to prevent the various means of welding deformation, still there is the distortion that exceeds permissible variation to exist, must correct.
Before H shaped steel flange plate arbor press development, our overlength, superelevation H shaped steel to being not easy on production line, correct adopts heating or large tonnage pressing machine orthosis to eliminate the welding deformation of flange plate.
But there is defective in these two methods.
At first, heating is eliminated welding deformation need consume a large amount of acetylene gas and oxygen, and energy consumption is high, weak effect, and efficient is low.
Secondly, adopt heating to correct distortion, can cause the steel plate hot-spot, influence the performance of steel, the security of construction steel structure is had negative effect.
The 3rd, adopt large tonnage pressing machine to correct the distortion of H shaped steel flange plate, need 4 to 5 people operation, but also need crane to cooperate, not enough maneuverability, and also production cost is than higher.
Summary of the invention
The purpose of the utility model is to provide a kind of H shaped steel flange plate arbor press, and it is rational in infrastructure, and is easy to operate; Dependable performance, the precision height is corrected in the distortion that can conveniently correct H shaped steel, T-steel flange plate and bar steel plate; Save manpower; High efficiency alleviates working strength of workers, reduces production costs.
The purpose of the utility model is achieved in that a kind of H shaped steel flange plate arbor press; On the back side at the crossbeam center of two symmetrical, parallel, piston rod hydraulic cylinder vertically downward is installed through affixed connection seat board; Affixed the T shape top in the end of piston rod; Be positioned at the suspension bracket that symmetry is being set respectively on two the parallel crossbeams in hydraulic cylinder both sides, the through hole on suspension bracket top and crossbeam movingly, be positioned at the suspension bracket lower end of two symmetries on the same crossbeam affixed the inside suspension hook of crotch is set in opposite directions; Be positioned on the connection seat board of hydraulic cylinder center line both sides affixed respectively symmetry upright little kickstand downwards, bogie wheel be installed in the lower end of little kickstand.
Utilize the principle of active force and reaction force to apply a constant load for H shaped steel or T-steel flange plate, make flange plate produce a reversal deformation, thereby reach the purpose of correcting welding deformation.
H shaped steel flange plate arbor press consists of the following components:
Crossbeam is the solid web girder of processing with steel, and the below of crossbeam is connected with dolly with hydraulic cylinder through connecting plate, and movably suspension bracket is equipped with at the crossbeam two ends, can adapt to the welding deformation of correcting different size H shaped steel flange plate.
Suspension bracket is the rod member of processing with steel plate, is used to the flange plate that connects crossbeam and corrected.The collar is arranged at its top, is enclosed within on the crossbeam, can on crossbeam, move, and the bottom is a hook, and hook is with the back side contact of top flange plate both sides during use.
Hydraulic cylinder places crossbeam and by between the flange plate of correcting, top is connected with bolt with the connecting plate of crossbeam below, and the top is equipped with in the below, and dynamic source provides power for it.
Little kickstand is the member of processing with angle steel, and there are four wheels the lower end, can make arbor press walking like a cork on flange plate by manpower.
T shape top is the T shape member that is welded with steel plate, and its top is connected with bolt with hydraulic cylinder, and the bottom contacts with flange plate.
Backing plate is a bar steel plate, and its effect is that the active force with suspension bracket passes to flange plate equably.
Use H shaped steel flange plate arbor press the welded H section steel of overlength, superelevation to be carried out the rectification of flange plate welding deformation; 3 workmans can easily accomplish in 3 hours, had improved operating efficiency, had alleviated working strength of workers; Reduce production cost, guaranteed the rectification precision.The device of having an effect both can be used for the rectification of flange plate, also can be applied to the jack-up construction of other project repeatedly, can not cause idle waste.
The utility model is rational in infrastructure, and is easy to operate, and dependable performance has realized the distortion that convenience is corrected H shaped steel, T-steel flange plate and bar steel plate, corrects the precision height, has alleviated working strength of workers, has reduced production cost.
