Program controlled heating element butt welding machine for tubes and fittings made of polyolefine from OD 355 up to OD 800. Complete with program controlled warming-up and cooling down cycle, controlled carriage movement after the heating and cutting period as well as an automatic joint pressure built-up. By input of the tube outside diameter (OD) and the wall thickness in mm / inch, the required values for the welding appear in the LCD display. This way it is ensured that all weldings are carried out with the same measuring and parameters. The specific welding pressure is program controlled. Thus all welding parameters can be automatically driven.
The machine has two movable carriages with two clamping elements which are built on the machine. Excluding diameter depending reducer inserts, two movable pillow blocks for the tube support, two supports and a try square. It is built on a rugged welded and anti-torsion steel frame. The machine carriage works with a linear prismatic guideway.
The clamping elements hydraulically powered consisting of three parts, therefore an exact central clamping is ensured. The clamping hydraulically results by two control buttons in the control desk. For the production of segmented archs both clamping elements can be displaced by 2 x 22,5°.
The electric planer with three-phase motor, 3 x 380Volt/2,0 KW, has a chain drive in a closed aluminium case and an automatic external chip removal. The working process of the planer is controlled within the program as subroutine.
The heating element (380 V/17 kW) is anti-stick coated with temperature electronically controlled and it automatically moves in and out by an interprogram.
All automatic functions are also seperately working by corresponding press buttons in the control desk.
