Abstract

PURPOSE:To enhance durability and to beautifully process and finish a thermally deformed part by inserting the projection provided to a resin member in the through-hole of other resin member and constituting a melting member thermally deforming the leading end of the projection of special ceramics. CONSTITUTION:When two members composed of a synthetic resin, for example, a lid member 2 and a box body 1 are welded in a device welding two members, several projections 3 composed of a synthetic resin are implanted in the upper surface of the box body 1 and the through-holes 4 in which the projections 3 are inserted are provided to the lid member 2. The leading ends of the projections 3 inserted in the through-holes and protruding from the surface of the lid member 2 are thermally deformed by a welding member 5 composed of a composite sintered material consisting of aluminum nitride and boron nitride. That is, the welding member 5 is fitted in and fixed to a metal block 7 heated by the heater 8 attached to the outer periphery of the block and heats the leading ends of the projections by heat conduction.

Description of the Related Art In the case of welding two members made of synthetic resin, one member is provided with a projection, the other member is provided with a through hole, and the above-mentioned projection is inserted into the through hole to project from the through hole. The tips of the protrusions are thermally deformed by the welded body of the welding device to weld both members together.

あった。The conventional welded body of beryllium copper or the like has poor wear resistance and corrosion resistance and thus has a problem in durability, and it is necessary to finely adjust the height of the welded body. Further, the welded body is maintained at a high temperature, the molten resin at the tips of the protrusions adheres to the welded body, and a so-called stringing phenomenon easily occurs, and there is a problem that the tips of the protrusions cannot be processed into a clean shape.

In addition, the temperature of the welded body is rapidly lowered, and the stringing phenomenon of the resin is less likely to occur. In addition, since the thermal conductivity is high after welding, the temperature rises quickly to the set temperature.

仕上げされる。Since the thermal conductivity of the welded body is improved, the temperature of the welded body is rapidly decreased after being heated instantaneously, and a stringing phenomenon occurs even if the tip of the welded body adheres to the welded resin portion. Instead, it is heat-deformed to a clean machined surface corresponding to the tip of the welded body.
