Abstract
A device for insertion of a plastic pipe section into a shaped plastic piece for welding in accordance with a heating element method. Two carriages, which each have a clamping element, are positioned on a base frame and can be displaced with respect to each other with a setting device. A heating device is pivotal, into and out of position between the two clamping elements with the clamped plastic pipe section and the clamped shaped plastic piece, by using levers pivotally mounted on the base frame. The heating device has a setting element with a cupped section for placing over the plastic pipe section and a cylindrical section for insertion into the shaped plastic piece. Universal use, requiring no set-up time, of the device for different diameters is achieved with the heating device having a plurality of different heating elements, each with a cupped and a cylindrical section. The heating device is pivotally mounted on the pivot levers in such a way that with the heating device in a set position, the heating elements can be optionally rotated between the two clamping elements, with the clamped plastic pipe section and the clamped shaped plastic piece.
