The WIDOS 16000 W CNC is a CNC controlled welding machine for the heating element butt welding of PE- and PP pipes and fittings from OD 800 (32" IPS) up to OD 1600 (63" IPS). It is designed especially for bends as well as T- and cross-pieces.
The machine is based on an extremely solid and torsion-free basic frame with precise high-capacity guidings and with a symmetrically arranged cylinder battery. The machine bed is performed in a flat construction in order to keep the table level as low as possible for easy equipment with clamping tools and welding pieces. The applied table drive enables exactly controllable and huge forces, features extraordinarily low driving forces and thus warrants a constant movement sequence during the welding cycle. Two machine tables are built on the basic frame which are both stored on precise and high-capacity guiding units and which can be diagonally shifted via spindles for misalignment compensation. The tables are stored afloat in order that balanced conditions during planing, aligning and heat-up are warranted. The tables are automatically limited in the opening stroke in order to shorten the tear-off ways during change-over.
The planer is electrically powered by an extremely high-torque three-phase drive motor and features an electronic soft starter for shock-free working. The special planer discs are optimized for the highest cutting performance and quiet drive by several cutting zones with adjustable chip flute width, and due to the large overhang besides the extreme center storing they are secured with additional support bearings against bending loads and bulges. The planer drives between the machine tables in electrical manner and is, in addition, hydraulically supported and locked within the treatment position.
The anti-stick coated 4-zone heating element is precisely controlled in electronic manner and fulfills the highest demands with regard to lifetime and temperature distribution. By using individually replaceable heating devices you will obtain precise temperature distributions and this enables easy repairs and individual changes without replacing the entire unit. The heating element is suspended from a solid girder frame with compensation of thermal expansion and, for the quickest movements, it drives in and out electrically within the machine tables during the change-over time.
In order to produce different fittings, there are available clamping tools in different versions and operations. They are mounted onto the machine tables in predefined drilling templates and may be quickly installed, aligned and fixed in solid manner by a special system with threaded jackets. The handling of the clamping tools is controlled via remote control that may be directly taken to the needed spot by the operator in order that no dangerous situations occur due to inadequate sight.The WIDOS 16000 W CNC is for the heating element butt welding of PE and PP pipes and fittings from OD 800 (32 IPS) up to OD 1600 (63 IPS). Furthermore, it is possible to fabricate high-quality fittings and bends as well as T- and cross-pieces.
The clamping tools for fabricating bends which have been optimized in its handling, solidity and tension force are additionally used to fabricate T-pieces of 45° and 60° and mounted on the tables being freely rotatable in their angle. The clamping of the welding pieces is effected over hydraulic knee lever system for the highest tension forces with adjustable locking position; the opening of the clamping tools is also effected by hydraulic drives with safety devices against hose breakage and fall-through.
The clamping tools for the fabrication of T-pieces are flexibly and universally constructed by a special geometry and assembly and thus may be used for all angles 45°, 60° and 90°. The assembly of the upper parts is effected manually by piling onto with a lifting device; the clamping may be optionally effected in hydraulic manner instead of manually by spindles as per standard. By a special design of the reducer inserts you may fix dimensions from OD 1200 (48) and smaller without using the heavy basic upper shells. This facilitates considerably the handling of the thus lighter tools as well as the optical insight at smaller dimensions and their alignment.
For easier operation of the machine during equipping and clamping, the machine is surrounded by a revolving platform with anti-skid steps. It acts as revolving stairway for comfortable ascending and descending and also as additional operator protection in form of a front barrier against unintentional entering into crushing zones. Furthermore, a safety fence is assembled in the rear machine area which shields the movements of heating element and planer. As additional safety measure during automatic processes, cleaning of the planing chips and operation by several persons, you may temporarily deactivate the hydraulic movement of the welding tables by a detachable key switch. Monitoring of welding parameters, welding time, welding pressure and welding temperature as well as recording and the reading of data via SD/USB device. Welding process automatically controlled by CNC unit. Simple programming possible through user panel.
