Automatic Light Pole Shut and Welding Machine

 Automatic Light Pole Shut-Welding Machine

Machine Model: 450/12000、550/12000 

1、Machine Overview:

     Light pole automatic shut and welding machine is a special conical pole welding equipment with high efficiency. The equipment is suitable for longitudinal seam welding of various metal cylinder, cone, prism, pyramid,square tube and so on.Shut and welding longitudinal seam by one machine. So that improve working efficient 3-5 times. Using CO2 gas welding and submerged arc welding . Automatic welding seam adjustment function to ensure accurate welding torch, welding automatically, without manual adjustment, welding seam forming beautiful.

3、Working Principle:

     The closing mode of the street lamp pole is that the hydraulic cylinder drives the chain and sprocket, and then the pinion drives the rack forward or backward to make the clamping wheel move synchronously to clamp/loosen the lamp pole. The clamping mechanism is fixed on a 50mm thick plate. The surface and middle holes of the plate are machined by the CNC machining center. During the clamping process, the gear and rack are always in a stress state, which requires high materials and processing technology. The pressure retaining valve and pressure gauge are installed next to the operation box, which is convenient for workers to adjust at any time.

     The street lamp pole is clamped on the mobile trolley and is pulled/pushed by the mobile trolley. The traveling speed of the trolley can be adjusted by the frequency converter. When welding, the welding is generally started from the end with larger diameter, and the clamping wheel is always close to the street lamp pole.

     The flux recycling machine is mainly used to recycle the flux. The welding pool is covered by the flux to ensure that the weld surface is smooth and beautiful.
