Abstract:
A method for shaping a part of a body of a plastic material in the form of a pin into a rivet, comprising the sequential steps of:moving at least one of the plastic part over a heating apparatus into an operative position, wherein the heating apparatus comprises: a helix shaped quartz tube having a helix axis and tube ends, a heat radiator arranged in the quartz tube and including an electrical resistance wire having ends, the resistance wire being connectable to a power supply, and a heat resistant element operatively connected to the quartz tube at least in a region of the tube ends, the heat resistant element comprising an access hole having a longitudinal axis parallel to the helix axis, wherein the heat resistant element is moved along the longitudinal axis onto the pin shaped plastic part in the operative position; securing the quartz tube in the operative position with respect to the plastic part using the heat resistant element while simultaneously heating the plastic part to a shaping temperature using the heating apparatus; and shaping the plastic part by introducing a rivet forming die onto the heated plastic part.
