Tube box production line set tube box material, straightening, group pair, internal and external angle welding, NC machining, end plate welding as one. The production line has the characteristics of high production efficiency, high machining precision, double-sided submerged arc welding and good welding quality.

The cutting machine is completely controlled by numerical control, which has the characteristics of high cutting precision, high efficiency, good cutting surface quality and small cutting deformation.

There are two kinds of press and one is Single-column hydraulic press for straightening the veneer after discharging the tube box; The utility model relates to a four-column hydraulic press, which is used to straighten the whole tube box after the welding of the tube box is completed, so as to strictly guarantee the shape and size of the tube box and provide the guarantee for the precision of the subsequent machining.

Used for pipe box plate groove processing, using different special tools can accurately process U groove, V groove. For the follow-up group, welding work to provide a strong guarantee.

The hydraulic cylinder is used to apply pressure on the plate surface or groove surface of the tube box when the tube box group is aligned to ensure the groove clearance and the wrong edge quantity between the plates when the tube box group is aligned. provide guarantee for subsequent pipe box welding work.

The welding machine adopts Lincoln welding machine, and the welding machine has the advantages of stable arc and good weld forming.

Using Lincoln welding machine, after the inner angle welding of the tube box, the outside weld of the tube box is welded with double gun and double side weld at the same time, and has the function of weld seam tracking. High welding efficiency, stable arc, good weld formation. And the double side welding can greatly reduce the welding deformation of the small tube box.

The welding quality is guaranteed by Lincoln welding machine, and numerical control is adopted, which can weld the end plate of pipe box of all sizes. there is no welding dead angle. greatly improve the welding efficiency and reduce the difficulty of welding.

Large work pieces from rough to finish, through the frequency control system control, high precision, high efficiency and simple operation can be done for planing, milling, grinding and other operations to achieve a multi-purpose machine. Digital AC servo control technology realizes high precision servo control of three-phase AC asynchronous motor. The machining center is used for drilling, reaming, buckling, tapping, milling,chamfer.etc. The numerical control is adopted, which ensures machining precision, improves machining efficiency and reduces labor intensity. ensure the overall quality of pipe box machining.
