摘要
The present invention is to increase the contact area between the tube receiving holes with the inner surface and the tube is inserted, receiving also relates to a ball inlet of the header of the condenser header pipe clad material to be welded to secure the tube tightly, the header is bent by the guide member (Guide burr) generated in the ball receiving part receiving the ball inside the inlet The bent portion of the cladding material is to be welded to the tube, and a guide member receiving the ball inlet portion bending doemeurosseo remove the slope formed on the inlet side and receiving conventional treatment a right angle to the rear and the fixed piece and the receiving holes of the boundary, such as the The configuration performed Fang the ball back and forth, and characterized by making it possible to increase the contact area between the tube or the like to the side member end portions to be extended to the rear side end portion in the receiving hole, ; header for the condenser pipe When the header is the header production method by the press molding, when molding the housing hole guide to bend the guide member to be generated in the receiving holes on both sides to be brought into close contact with the ball receiving step of bending the inner wall member; Right angle end portions and boundary processing step of processing a static convenience perpendicular boundary of the receiving hole; Batten primary bending step of bending the fixed part of a header side direction; Folding batten secondary bending step is in the inner side direction of the fixed end portion to wrap both ends of the tank (rear);. Is characterized by including a
