Background technique

In the high-frequency welding thin-walled H-shaped steel production line, in order to make the web and the wing plate normally complete the metallurgical bonding, it is required that the web cannot be deformed or displaced during transportation along the guide box. However, the existing production line does not have supporting devices to achieve no deformation and no displacement, because the center alignment of the web is only completed by the strip steel suspension and tension control device, pinch roller and web torsion device during the web transportation process and verticality control, but there are no other effective means or measures to keep the center of the web aligned and ensure its verticality, so that the web will be deformed and twisted in the guide box or cannot be kept vertical before it is assembled and welded, which directly affects Normal welding of web and flange. Especially for thin-walled webs, it is easier to cause web distortion and deformation, which seriously affects the quality of finished products. At present, most foreign production lines adopt relatively complex automatic detection and alignment technology for this problem. Not only the investment is large, but also the operation control is complicated. After localization, there is a problem of high failure rate. Therefore, it is necessary to improve the existing production line technology.

The pressing mechanism is an L-shaped pendulum, the long side of the L-shaped pendulum is hinged on the support frame through the hinge shaft, and the end of the short side is fixed with a pressing wheel, and the pressing wheel is placed in the through groove of the guide box , the short side is connected to one end of the spring seat with spring, the other end of the spring seat is connected to the screw, and the other end of the screw is screwed to the screw hole of the end plate fixed on the support frame, so that the spring can be compressed by rotating the screw as required. The L-shaped pendulum swings around the hinge shaft, and the pressing wheel is pressed down to contact the upright web to maintain the center alignment and verticality of the upright web, effectively preventing the web from moving, deforming or displacing.

The L-shaped pendulum frame includes two L-shaped plates arranged in parallel to keep a distance between them, a connecting plate is arranged between the two L-shaped plates, and the long sides of the two L-shaped plates are hinged to the L-shaped support frame through the hinge On the long side, the pinch wheel is fixed between the short side ends of the two L-shaped plates through the axles at its two ends.

The outer end of the screw rod is provided with an adjustment handle so that the handle can be operated to rotate the screw rod to compress the spring so that the L-shaped pendulum frame swings around the hinge axis, so that the pressing wheel contacts the upright web to maintain the center alignment and verticality of the upright web. Effectively prevent the vertical web from moving, deforming or displacing.

One or more through grooves on both sides of the guide box are arranged symmetrically or asymmetrically to meet actual production needs.

The utility model has the following advantages and effects: adopting the above scheme, one or more anti-deformation devices can be installed symmetrically or asymmetrically on both sides of the guide box according to the production needs, and when necessary, the screw rod is rotated to compress the spring to make the L-shaped pendulum stand around After the hinge shaft swings, let the pressure wheel pass through the slot of the guide box and contact the upright web, so as to maintain the center alignment and verticality of the dynamic upright web, and effectively prevent the deformation or displacement of the upright web during transportation. Stretch the spring to make the pressing wheel leave the upright web in the guide box, that is, guide the web, and adjust the screw to meet the transportation requirements of webs of different thicknesses, ensuring that webs of different specifications and thicknesses are transported properly. No deformation or displacement in the center, providing a reliable guarantee for subsequent production.
