Hürner HWT 500 CS

HÜRNER HWT 500 CS servo-operated workshop system for manufacturing PE, PE 100 RC, PP, and PVC-U, PVC-C pipes, segmented bends, and fittings, fitted with narrow aluminum master clamps. The design of the machine is such that pipes and segments up to O.D. 500 mm / 20“ with any SDR ratio up to SDR 9 can be processed. The system was developed under the machin ery directive 2006/42/EC as amended and is set on a welded and bolted, totally heavy‑duty support frame resistant to warping by design. Both the movable carriage of the system and the console carrying the heating element and the facing tool travel on precision‑engineered, heavy load‑bearing trapeze‑shaped guides constructed with smoothly travelling runner blocks. A pneumatic cylinder will remove the heating element from in‑between the components in no time, enabling change‑over in as short as 2 seconds. The facing tool assembly, too, is inserted and removed automatically. The swiveling master clamps on both sides can be rotated by up to 2 × 22.5 deg. and also feature horizontal and vertical adjustability, to allow for compensating any misalignments.The facing tool has a rugged chain drive mecha nism and is inserted and fastened between the component butts as easy as ABC thanks to a gas‑pressure cylinder. The heating element temperature control and the application of the welding force precision controlled by a servomotor are performed in compliance with the standard applicable to the operation (DVS, UNI, WIS, NEN, etc.). All welding parameters critical for a high quality and reproducible welded joint, it goes without saying, are monitored for the entire welding process and saved to one of the 10,000 welding reports the system memory holds. In its standard delivery, the machine features a high‑resolution color display touchscreen. This device allows entering and displaying both all required component parameters and the needed traceability information. A unique feature in the field of butt weld ing that this system version offers is the user access management using RFID technology for foolproof and extremely convenient input of the data into the system, rather than the bar code and scanning pen that have been common. Also a revolution in workshop machines is the possibility of preheating by means of a preheating cylinder. As with all HÜRNER CNC systems, a USB interface port is also provided for downloading the welding data to a USB stick as a PDF ab stract or extended report or for archiving them in the HÜRNER DataWork Professional format. Combining this to HÜRNER WeldTrace app, which has QR code scanning from label tags implemented, tracing back any and all weld ing and project data flawlessly is guaranteed even years after the work was completed. The welding data can also be transferred via the in‑house LAN / Wi‑Fi network to a printer or to the DataWork database software.
