Processing Strength
Longhua Technology has more than 900 sets of advanced processing equipment and has invested more than 100 million yuan to purchase CNC plasma cutting machine, CNC gantry machining center, CNC hydraulic bending machine, large three-roll plate rolling machine, CNC internal and external ring seam welding center, tube plate welding machine, Lin Ken welding machine and other well-known processing equipment at home and abroad, effectively improve production efficiency and ensure product quality.
Company adopts the international standard construction of large-scale joint-span plant, with 100 T double-beam crane and other lifting equipment, all kinds of large-scale production lines, such as brazing furnace production line, large flat pipe production line, pipe automatic welding production line, square pipe automatic welding production line, paint drying production line and other supporting special facilities.
Pipe Box Production Line
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.
CNC flame/plasma three cutting torch cutting machine
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.
Press
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.
CNC Gantry Milling
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.
Tube Box Counter
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.
Inner Angle Welding Machine
The welding machine adopts Lincoln welding machine, and the welding machine has the advantages of stable arc and good weld forming.
External Angle Welding Machine
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.
Tube Box End Plate Welding Machine
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.
CNC Machining Centre
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.
Field 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.
