(57) [Summary] [PROBLEMS] To provide a method of mounting an intake pipe of an intake manifold of an engine without cracks or breakage. SOLUTION: In an intake pipe mounting method of inserting an end of an intake pipe 10 of an intake manifold of an engine into a hole 14 of a face 13 of a collector 2 or a flange 3, the end of the intake pipe 10 is plastically deformed. The small diameter portion 20 is formed by performing a diameter reduction process, and a punch 24 having a diameter larger than that diameter is press-fitted into the small diameter portion 20, and the intake pipe 10 is formed.
The work hardening is caused by expanding the diameter of the end portion, and the work hardened portion having the increased diameter is joined to the hole 14 by brazing or welding. Next, another punch 26 is press-fitted from the work hardening portion side into the work hardened portion having the increased diameter in the hole portion 14 to make the diameter of the end portion of the intake pipe 10 uniform, and finally the work hardened portion 19 is formed. obtain.
