この発明はろう付け品の製造方法に係り、特に
母材の貫通孔内にろう材を圧入固定するようにし
たろう付け品の製造方法に関する。[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a method for manufacturing a brazed product, and particularly relates to a method for manufacturing a brazed product in which a brazing material is press-fitted and fixed into a through hole of a base material. .
一般に金属と金属とを接合する一手段としてろ

Brazing is generally used as a means of joining metals together, but automation of the entire brazing process has not progressed because it is difficult to automate the supply of brazing filler metal. Under these circumstances, the applicant first stacked the brazing material on the base material, punched it out from above with a punch, press-fitted and fixed the brazing material into the through hole punched in the base material, and then We have provided a method for manufacturing brazed products that can braze metal members by melting materials (see Japanese Patent Application Laid-Open No. 16745/1983).

が脱落するという問題もあつた。 However, although the proposed manufacturing method had a remarkable effect on automating the brazing work, it was not possible to press fit into the base material during pre-treatment processes such as transportation, degreasing, and pickling before brazing. There was a problem with the taro wood falling off. In addition, when it is necessary to bend the base material and the bending part is set near the press-fitting point of the filler metal, the base material will be subjected to tensile force, which will cause the press-fitting tightening force to increase. There was also the problem that the brazing filler metal would fall off due to a decrease in the temperature.
さらにまた、ろう付け時に発生するポイドの圧
力によつてろう材が反対側に押し出され、毛細管
現象により接合間隙にろう材が浸透せずろう付け
されないという問題もあつた。 Furthermore, there was a problem in that the brazing material was pushed out to the opposite side by the pressure of the poids generated during brazing, and the brazing material did not penetrate into the bonding gap due to capillary action, resulting in failure of brazing.
そこで、この発明の目的は母材中に圧入された

う。 Figures 1A, B, C, and D show the entire process of the first embodiment of the present invention, and reference numeral 1 in the figures indicates a base material, and this base material 1 is a brass plate with a plate thickness of 2 mm.
BsP2A-1/2H is used. This base material 1
On the other hand, in process A, a stepped punch was used to form a 3.1 mm square
A large diameter hole 2a with a depth of 1.7 mm and a small diameter hole 2b with a 3 mm square and a depth of 0.3 mm are bored. In step B, the large-diameter hole 2a of the base material 1 is used as a die with a cutting blade to cut and press-fit the flat silver brazing material 3. At this time, the silver brazing material 3 is
It is held by a stepped portion at the bottom of the large diameter hole 2a.
Next, in step C, insert a 3.2 mm square punch into the large diameter hole 2a.
The hole is expanded by pushing it inward, and the protruding piece 4 is caulked with the end face of the punch, thereby performing the first stage caulking process.

３に対する締付力が弛んで脱落することはない。 By applying the first and second stages of caulking to the front and rear hole walls of the silver filler metal 3 press-fitted into the base metal 1 in this way, the silver filler metal 3 is inserted into the protrusion piece 4 and the tongue piece 5. It is possible to clamp and securely hold it securely. Therefore, the silver brazing filler metal 3 does not fall off from the base material 1 during the pretreatment process as in the conventional method,
Further, as shown in FIG. 2, even if the base material 1 is bent at right angles near the silver brazing material 3, the tightening force against the silver brazing material 3 will not loosen and the material will not fall off.

真直穴６の出口側の縁部にツブシ加工を施し、穴
の内面に舌片５を形成する（工程Ｂ参照）。 In Figure 3A, the base material 1 is Cu-Fe with a thickness of 3 mm.
- Prepare a Zn-1/2H plate and drill a straight hole 6 (straight hole 6) with a diameter of 3.8 mm. The edge on the exit side of the straight hole 6 of this base material 1 is machined to form a tongue piece 5 on the inner surface of the hole (see step B).
次に工程Ｃにおいて、母材１の真直穴６を切刃

ろう材３の喰い付きが良好となる。 Next, in step C, the straight hole 6 of the base material 1 is used as a cutting edge die to cut and press-fit the silver brazing material 3, and the silver brazing material 3 is locked with the tongue piece 5. The punch used in this step preferably has an R-shaped tip, so that the silver brazing material 3 can be well bitten into the wall of the straight hole 6 of the base material 1.
次いで、直径4φのポンチを真直穴６内へ押し

Clamp the material 3 (see Fig. 3D). At this time as well, it is preferable to make the diameter of the inner projecting piece 7 smaller than the diameter of the outer tongue piece 5 so that it can oppose the pressure against the poid.
このような実施例においても、母材１内に銀ろ

る。 In FIG. 5, a long plate-shaped base material 1 is sent in the direction of arrow P with the brazing surface facing upward, and during this time a hole 8 for inserting the silver brazing material 3 is drilled, and then a concentric A gas vent through hole 9 is bored at the position. Next, a long brazing material 3 is formed in the direction Q perpendicular to the base material 1.
is automatically fed, and the filler metal 3 is punched out using a punch with the same diameter as the hole 8 at a position that intersects the base material 1 and is aligned with the center of the hole 8 and the gas vent through hole 9, and the punched piece is punched out with a hole. 8 is press-fitted. Thereafter, protrusions 10, 10, 10 are caulked at three positions spanning the boundary between the silver brazing material 3 and the base material 1. This caulking process moves the meat on the base metal 1 side to the outer peripheral edge of the silver brazing material 3, thereby preventing the silver brazing material from rotating and slipping out. Incidentally, FIG. 7 shows a state in which a metal part 11 is placed on the silver brazing material 3 and brazed.

As is clear from the above description, according to the present invention, after the brazing material is press-fitted into the hole in the base material, the meat on the base material side at the bonding boundary between the two is raised to lock the brazing material. The brazing material can be securely fixed to the base material without rotating or coming off. Furthermore, even when bending is performed on the base material near the location where the brazing filler metal is press-fitted, the brazing filler metal will not escape from the hole in the base metal.
