Description

Shaped steel edge of a wing straightening mechanism

Technical field

The utility model patent relates to a kind of straightening mechanism of shaped steel, especially edge of a wing straightening mechanism when welded H section steel, T-steel.

The welding deformation straightening mechanism, specifically in welded H section steel (shape resembles I-steel, is pieced together by two transverse slats and a riser and forms) or T-steel (forming) process, owing to weld at riser two side welds by a transverse slat and a riser assembly, temperature distortion, shrink the commissure in the middle of the transverse slat, and transverse slat two side direction weld seam sides are drawn in, lift, transverse slat becomes the V font by in-line, the effect of this straightening mechanism is exactly with transverse slat, and depress on the both sides of perk, makes transverse slat return to the in-line state.

Background technology

H, T-steel have been widely used in every field such as building, petrochemical industry, bridge at present.4 processing steps are adopted in the manufacturing of H, T-steel usually, are respectively cutting stock, assembling, welding and rectification, corresponding these 4 steps have 4 equipment to finish each function, are respectively cutting machine, the upright machine of group, bonding machine, arbor press, the thickness of being made workpiece generally can arrive about 40mm.

Development along with technology, some equipment is with the assembling of workpiece, welding and correct 3 processing steps and be incorporated on 1 equipment and finish has reduced workpiece the flowing of equipment room, and has simplified operation simultaneously, also reduced the staff, because 3 equipment are synthesized an equipment, reduced the occupation of land in workshop, improved the output capacity of unit are, but since with 3 processing steps be incorporated in finish on 1 equipment after, thereby the volume of each mechanism just had restriction.

The rectification mechanism of transverse slat is such in the workpiece: as shown in Figure 1; The transverse slat middle lower portion has a driving wheel, driving wheel drive workpiece moves forward and backward thus, respectively have one to correct wheel on the top, both sides of transverse slat V-arrangement perk, these 3 wheels form 1 and correct the chamber, workpiece enters corrects the chamber, by the extruding of 3 wheels, carries out the rectification of workpiece, according to the thickness of workpiece difference, need to adjust to go up and correct the height of taking turns.

In the prior art, the straightening mechanism part, last rectification wheel 5 is installed on the lifting slider 15, lifting slider 15 is installed in the elevating bracket 16, and elevating bracket 16 tops are equipped with hydraulic cylinder 17, and hydraulic cylinder 17 is connected with elevating bracket 16, hydraulic cylinder rod 18 is connected with elevating bracket 16, promote lifting slider 15 by hydraulic cylinder 17 and slide up and down, move up and down to form suitable rectification chamber 14, finish the rectification work of whole work-piece thereby drive to correct to take turns.

The shortcoming of straightening mechanism in the prior art:

1) owing to adopt lifting slider, elevating bracket drives by oil cylinder, and structure is huge;

2) because arbor press mechanism is big, make operational difficulties such as welding gun adjustment, replacing;

3) straightening mechanism adopts the hydraulic pressure adjustment, thereby can not guarantee in the big or small accuracy of correcting the chamber, needs the workman constantly to measure adjustment, cost height, troublesome poeration.

The utility model content

Goal of the invention of the present utility model is, provides a kind of volume little, simple to operate, safe and reliable, and guaranteed the stability of correction quality, reduces the dependence to workman's experience, a kind of shaped steel edge of a wing straightening mechanism of having improved labor productivity.

The utility model is achieved in that

A kind of shaped steel edge of a wing straightening mechanism comprises frame and apparatus for correcting, and wherein said frame and the upper guide post that be arranged above and below parallel by two and following guide pillar are connected with the wallboard that is respectively in both sides respectively and form; Described apparatus for correcting comprise correct wheel, be installed on the following rectification wheel at described upper guide post middle part and be respectively in described correct the wheel both sides down and be set in described upper guide post simultaneously and described guide pillar down on and sliding seat slidably, be connected with screw with screw mandrel between described sliding seat and described wallboard, the end of described screw mandrel is provided with handle; Described apparatus for correcting also comprises eccentric shaft, and described eccentric shaft is installed on described sliding seat upper end, and the output of described eccentric shaft is equipped with corrects wheel.

The utlity model has following advantage:

1) changes apparatus for correcting into eccentric shaft structure, reduced the volume of apparatus for correcting, made things convenient for the operation and the adjustment of other parts.

2) the big I in rectification chamber mixes up in advance according to technology, need not constantly to adjust when work, thereby has alleviated staff's working strength, also the precision of the rectification of Ti Gaoing and speed.
