DEFORMATION PREVENTING JIG FOR USE IN SHAPING HEAT TRNSMITTING TUBE BY WAY OF EXPLOSIVE TUBE EXPANDING

摘要

PURPOSE:To provide a jig for preventing deformation of heat transmitting tubes of heat-exchanging plate in shaping the same by way of explosive tube expanding method, which is firmly fixed in place when expanding the tube, so as to prevnt that cross section of the heat transmitting tubes be deformed into an elongated circle after the shaping and to attain high accuracy in shaping the tube by way of explosive tube expanding method.
