Welding machine for the heating element butt welding of PE-, PP- and PVDF-pipes and fittings from OD 90 up to OD 315 mm. With electro-hydraulic adjusting device for the control and application of the welding pressure, planer with electrical chain drive in a closed aluminium housing, external chip removal, holding bracket for the heating element, adjustable timer, two transport handles, basic clamping device (without diameter depending reduction inserts) swivelling on each side up to 15° for the welding of segmented bends and fittings.

The right-hand clamping tool is axially movable for adjustment of diameter tolerances. Hydraulic unit, planer, heating element and clamping tools can be easily removed for transporting the machine even into difficult accessible rooms.

Heating element anti-stick coated, with connection cable and plug, control lamps for interval and system checking, electronic temperature control according to DVS 2208.

The welding with power regulation is very problematic with plastics of low viscosity if well-aimed rest melt values have to be created. On the other hand procedures with joining way limitations have the disadvantage that a tension in the weld already occurs after a short cooling down period by the degeneration of the material’s thermal expansion. A combination of both procedures would be ideal during which a joining way limitation is effected to secure the rest melt in the first part of the cooling down period. It should only be made possible to switch to power regulation after exceeding a certain welding force to be defined.

Manual welding machine for heating element butt welding of PE, PP and PVDF pipes from OD 160 up to OD 500 and for the rational fabrication of fittings, bends and T- and Cross-pieces of highest quality in the workshop.

The machine is mounted on an extremely solid and torsion-resistant basic frame and has two movable machine tables running on precise guiding units highly capable of bearing. The table drive allowing exactly controllable forces at smooth running is constructed in an ideal way with respect to the demands of the plastics processing. The floating bearing of the tables enables a very solid suspension of heating element and planer. Both are swivelled between the tools and meet highest demands on quality and service life.

The clamping devices which have been optimized in handling and stability are mounted swivellingly onto the tables for the fabrication of fittings and may be shifted horizontally for an easy mismatch compensation. Vertical compensating motions are available upon request. Besides the solid versions of 15° resp. 22,5° which are principally used for the fabrication of segmented bends, small steel versions are available for the clamping of even the smallest straight stubs of the fittings like e.g. flanges. The welding pieces are clamped manually via spindles in the standard version and may be optionally supplemented by hydraulic systems.

The anti-stick coated heating element has an electronical temperature control and meets highest requirements on service life and distribution of the temperature.

The electric planer with chain drive in a closed housing with high torque performance has been optimized in high cutting performance at smooth running.

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 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 heating 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-torsional three-phase drive motor and disposes of an electronic start smoother 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-zonal heating element is precisely controlled in electronical 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 electrically drives in and out within the machine tables during the change-over time.

In order to produce different fittings, there are 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 clamping tools for fabricating elbows 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 its 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 basis 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 peelable key holder.

Hydraulic control unit with high-performance pumps, pressure gauge and easily usable control valve. The working height of the whole welding machine is deeply lowered for facilitating work and furthermore equipped with regulating feet for a safe mounting.

Electric planer and heating element, thermostatic control, swivelled in by means of a lifting device. The heating element can be suspended into a seperate carrier frame.
