Specialised bending equipment for pipe forming

LVD-HD’s PPF Series multi-cylinder bending machines are designed for forming large pipes up to 1,524mm diameter and are available in capacities up to 10,000 tons, 14.1m configurations. They are suited to address the pipe manufacturing needs of the oil and gas industries. These heavy-duty, specialised forming presses feature front and back feeding and support systems, roller conveyor, side discharge system, and LVD’s exclusive Touch B control. This multiple cylinder machine is driven by an electro-hydraulic servo synchronous system, providing precise control of the ram and adjustment of the Y-axis to compensate for material variations. Positioning accuracy is 0.05mm with repetitive accuracy of 0.03mm. PPF bending machines may be equipped with automatic feeding, charging and discharging systems for increased efficiency. LVD’s custom PPEB-H press brakes suit pipe forming and specialised section/profile forming applications with the ability to handle workpieces up to 14m long (28m long on tandem machines). PPEB-H Series machines are available in capacities from 400 tons up to 3,000 tons in stand alone configurations, as well as tandem designs up to 6,000 tons comprised of two press brakes, servo- controlled with state-of-the-art hydraulics and electronics. PPEB-H press brakes are provided as a turnkey system including press

brake, and CNC feeding – evacuation automation and CNC forming tools. Key features include Touch B CNC control, an icon-driven touch screen system that works in conjunction with an on board Windows ® operating platform and LVD’s CADMAN-B ® programming software to simplify and shorten programming and production time. LVD’s Impuls Series of flying optics laser cutting systems features a large table capacity to handle sheet sizes up to 3.10 x 12.5m. Uniquely designed for heavy plate cutting and profiling, these high performance laser cutting machines

Impuls also features a unique patented technology, ALC (adaptive laser cutting). ALC optimises laser cutting in thicker mild steel materials by using dynamic feedback to monitor and regulate laser power, speed and assist gas pressure in real time during the cutting process. ALC can increase productivity up to 10 per cent, maximises part quality and eliminates scrap or rework. The LVD Group is a manufacturer of a comprehensive range of sheet metalworking machine tools and software solutions, including laser cutting systems, punch presses, press brakes, guillotine shears and mid-level automation systems, integrated and supported by its CADMAN ® PC-based Windows ® compatible software. LVD-HD is the joint venture company of LVD Company nv and Hubei Tri- Ring Metalforming Equipment Co Ltd (HD). The company produces sheet metalworking equipment, including large customised press brakes, standard format press brakes and shears.

process mild steel up to 25mm; stainless steel up to 15mm. A constant beam length system achieves consistently accurate cutting results throughout the complete work envelope. Optional features include NC Focus control, process control, automatic shut down, and CADMAN ® offline programming software. Impuls is offered with a laser source of 4 or 6kW.
