Welding apparatus of thermoplastic resin material, welding method, and the pressing unit for welding equipment

摘要

Thermoplastic resin material (2a, 2b) the welding target part with the surface in the vicinity of, has a pressing means to pressure the axis perpendicular to the direction of the core material (1), and heating means, by pressure means, thermoplastic The surface of the welding target part of the resin material is pressed at a predetermined pressure and then, without changing the relative positions of the pressing means and the thermoplastic resin material welding target part of the surface of the compression region, the compression continues the compression region The widens in the axial direction of the core member, the welding target part of the thermoplastic resin material is deposited by heating with heating means, after welding completion of stopping the compression of the thermoplastic resin material by lowering the pressure of the compression means, the core material and it is configured to take out the thermoplastic resin material that covers the.
