H-beam combined machine Product description This assembling-standing machine is applicable to the assembling of uniform and variable cross-section of h profiled bar or t profiled bar steel. Adopt vertical assembly-standing type, compared with the traditional machines; the degreeof automation on will be further improved. During operation, it is unnecessary to adjust sizes. The hydraulic clamp, positioning clamp and point welding output may be completed at the same time, so the productive efficiency improves. Performance and structural features The bidirectional automatic centering device can automatically complete the centering and positioning of plate without manual check and adjustment the main machine adopts two groups of automatically hydraulic clamp structure of flange and web, the swing problem about feeding web is solved. In the double automatic co2 point welding machine head symmetric device, the welding gun adopts pneumatic feeding and mechanical guide wheel tracing, the quality of welding is high. The main control system is controlled by the imported frequency changer and the logical controller , the control calve of hydraulic system is controlled by the advanced fold valve.
