H-beam automatic assembly machines have been widely used in recent years, with stable operation and low failure rate. 

Its main function is the fastening calibration, positioning, automatic centering and spot welding of the web and flange plates of H-shaped steel.

Automatic centering accuracy (less than ±1 mm). 

No need to adjust every time (use eccentric for fine adjustment).

Using Japanese Mitsubishi programmable controller and AC inverter, high production efficiency

It has a stable working condition, and the welding torch is equipped with an arc-following device to ensure the quality of spot welding.

1.The flange and web are automatically centered and clamped to avoid frequent measurement and adjustment of the center during the assembly process, which saves time and effort.

The web clamping wheel adopts a four-group arrangement of front and rear, and a two-layer combination structure, which can correct the small curvature of the web and then assemble it, improve the accuracy of the assembly, and solve the phenomenon of assembly tail wobble;

2.The H-shaped steel is precisely aligned, and the operation is simple and convenient.

The upper pressing wheel and the spot welding position are on the same plane, and the spot welding is done after compaction to ensure the accuracy of the assembly;

A tooth-inlaid clutch is installed on the coupling part of the flange plate clamping mechanism, which can assemble the off-center H-beam steel of the web, and the range is between 75 mm and 500 mm;

3.The design of automatic spot welding arc guide mechanism is scientific. 

The expansion and contraction of the welding torch is driven by a light oil cylinder, and the connection part adopts active joint and spring compression to ensure the stability of the pressing force between the guide wheel and the work-piece and the welding torch can follow the guide wheel to center the weld.
