する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rivet caulking method in which a rivet is caulked while drilling a pilot hole in a resin part.

でかしめる方法等が用いられる。 As an example of the caulking method for resin parts, for example, as shown in FIG. A method of inserting the pin 9' into the prepared hole 3 and forcibly press-fitting the pin 9' into the rivet to swage the tip of the shaft into a chrysanthemum shape, or inserting a semi-tubular rivet 6 into the prepared hole 3 as shown in Fig. 2. By inserting and caulking with a crimping die 8, or by filling the washer 4 as shown in Fig. 3,
A method is used in which a solid rivet 7 is inserted into the prepared hole 3 and caulked with a fastener 9 or the like.

因ともなる。 In each of the above methods, it is necessary to drill pilot holes 3 in the resin parts 1 and 2 in advance. There are methods for perforating the resin part during molding or after molding, but the former requires an expensive mold, and the latter requires a separate process and a cutting mold. Also, general-purpose resins have difficulty achieving dimensional accuracy, so if there are many rivet crimping locations, the positions of the holes will be misaligned. Therefore, it is necessary to make the pilot hole larger, but since resin is weaker than metal, in order to obtain the desired peel strength, the rivet head must be made larger as the diameter of the pilot hole increases. Furthermore, the fastening area must be expanded by inserting a washer. Furthermore, in addition to the increased man-hours for inserting washers and aligning holes, large quantities of washers are consumed due to mass production, which is a factor in increasing costs.

である。 As mentioned above, the present invention relates to a method of caulking a resin part while drilling a pilot hole with a rivet, and is intended to solve the problems of the various caulking methods described above, and also to solve the problems associated with forming the pilot hole. To provide a method for crimping rivets on resin parts in which debris is effectively used for crimping.

らかしめ完了までの過程を順を追つて示す。 FIGS. 4 to 8 show the rivet caulking method for resin parts according to the present invention, step by step, showing the process from rivet driving to completion of caulking.

図において、１０，１１はかしめ付けすべき樹
脂部品の一部を示し、１２は本発明に適用される
リベツトを示す。 In the figure, numerals 10 and 11 indicate parts of the resin parts to be caulked, and numeral 12 indicates a rivet applied to the present invention.

通部を形成する。 The rivet 12 has a shaft hole 12b with a bottom that opens at the end surface of the shaft 12a. The shaft hole 12b extends along the axis of the shaft 12a, and the shaft cylindrical portion 12c in which the shaft hole 12b is formed is caulked with a solid shaft extending from the shaft cylindrical portion 12c to below the neck of the head 12e. The portion 12d forms a penetrating portion.

る。 As shown in the figure, the resin parts 10 and 11 are supported on a jig 13, and the rivet 12 is driven into the resin parts 10 and 11 that do not have the pilot hole, and the chips 10a generated by driving the rivet are removed. ,11
A is press-fitted into the shaft hole 12b from the opening in the end face of the shaft portion.

る。 As the rivet shaft 12a advances to drive the resin parts 10, 11, scraps 10a, 11a are removed from the shaft hole 1.
2b, and the tip of the rivet shaft, that is, the shaft cylinder portion 12c.
As the tip passes through the resin parts 10, 11 and reaches the flat surface of the jig 13, the scraps 10a, 11a filling the shaft hole 12b are compressed and deformed into a flat shape by the jig 13, while at the same time being compressed. Shaft hole 1 under deformation
2b, that is, the shaft cylinder portion 12c, is forcibly expanded, and the caulking is completed. FIGS. 6 to 8 show this deformation process. That is, the scraps 10a, 11a that have completely filled the shaft hole 12b are at least at a position where the tip of the shaft cylinder portion 12c hits the jig 13,
Compressive deformation occurs, and this compressive deformation force effectively contributes to the forcible expansion of the shaft cylinder portion 12c. This also effectively prevents slumping during initial expansion. The shaft cylindrical portion 12c is completely expanded, and the scraps 10a and 11a are expelled into the outer hole as crimping is completed.

る。 In order to bring about the above-mentioned phenomenon more effectively, the volume of the shaft hole 12b is set to be less than or equal to the volume of the punched scraps 10a, 11a punched out by the rivet 12. This relationship is between the thickness h1 of the resin parts 10 and 11 and the shaft hole 12b.
can be replaced by the relationship h 2 ≦ h 1 for the depth h 2 of . As a result, as shown in FIG. 6, the shaft hole 12b is completely filled just before the tip of the shaft cylinder portion reaches the jig 13, and the deformation can then be turned into compression. This initial compressive deformation increases the internal pressure P 1 of the shaft hole 12b (external pressure P 2 <internal pressure P 1 ) as shown in FIG.
It can be seen that the tip of the shaft cylindrical portion 12c is slightly displaced outward just before reaching the position 3. It is recognized that this minute displacement effectively acts on the normal initial expansion of the tip of the barrel barrel, and more effectively prevents the phenomenon of the barrel barrel becoming unseated.

とは前述の通りである。 According to the present invention, the resin part 1 is formed by driving rivets.
It is possible to caulk while drilling the pilot holes to 0 and 11, and also to remove the punched waste 10a,
11a can be effectively used for caulking. The step of drilling pilot holes into the resin parts can be omitted, and the fastening force for the resin parts 10, 11 can be greatly improved compared to methods such as drilling pilot holes in advance and caulking with rivets. That is, the peel strength of the resin parts 10, 11 is significantly increased. As mentioned above, the action of the rivet 12 and the action of the scraps contribute to the improvement in strength.

本発明によればワツシヤーを使用せずに必要且

下穴加工後の穴合せ工程も省け、ワツシヤー使用
を不用とし量産上著しく有利である。 According to the present invention, necessary and sufficient fastening force can be obtained without using washers. It also eliminates the hole matching process after drilling the pilot holes in resin parts, and eliminates the need for washers, which is extremely advantageous in mass production.

This effectively acts as a forced expansion force from the tip of the cylinder, and the expansion action of the scraps from both sides prevents the tip of the shaft cylinder from buckling, forms the beginning of expansion, and allows for proper expansion and caulking. can be reached. Therefore, the jig can easily induce expansion of the tip of the shaft cylinder even on a flat surface.
