Detailed description of the preferred embodiments
The invention will be further described with reference to the drawings and the specific examples.
As shown in fig. 1, the rivet designed by the invention is not only suitable for being implanted into the inclined plane metal part 101, but also does not affect the appearance of the product after being implanted into the inclined plane metal part 101, and is composed of a working part and an implantation end for being implanted into the inclined plane metal part 101, and the hardness of the rivet of the product is larger than that of the metal part 101. The implant end is connected to the bottom end of the working portion for mounting other parts. The working part must be provided with a hole 3 in the middle, which hole is drilled from the top end of the working part, the distance H from the bottom surface of the implant end is less than 2 times the diameter D of the working part (H < 2D), or the hole is extended to extend through the implant end (h=0), as shown in fig. 2, the limitation of the hole is to weaken the strength of the root of the working part of the rivet, so that the root of the working part can be slightly bent and deformed when the product is riveted. Meanwhile, the hardness of the rivet is larger than that of the inclined metal part, so that the root bending deformation of the working part keeps that the rivet can integrally follow the bending of the rivet and is not easy to deform when the implantation end is riveted, and the rivet can be better attached in the blind hole for riveting.
The implantation end is sequentially provided with an upper panel 4, an annular groove 6 and a bottom panel 5 from top to bottom, the upper panel 4 is polygonal in shape, the bottom panel 5 is circular in shape, and the diagonal length of the upper panel 4 is greater than the diameter of the bottom panel.
Further, the height of the implantation end is smaller than the thickness of the metal part 101, and the bottom surface of the implantation end is not exposed on the surface of the metal part 101 when the metal part 101 is riveted to the inclined plane according to the present invention.
Still further, the height of the annular groove 6 is greater than 0.2mm, so that when the rivet is riveted to the inclined plane metal part 101, the rivet implantation end has a space for accommodating the deformed material of the metal part 101 when the deformed material of the inclined plane metal part 101 is deformed.
To further illustrate how rivets designed according to this invention can be used to attach other components, one can use the following two ways or others. One can provide a guiding ramp 1 at the top of the hole, as shown in fig. 1 or 2, and a thread segment 2 immediately below the guiding ramp 1. The guide inclined plane 1 is used for better installing other parts of the product, such as when the screw is locked, the screw firstly passes through the guide inclined plane 1 contacting with the working part so as to have the functions of guiding and automatically centering the screw, thereby reducing the operation difficulty of people when the screw is locked. The thread section 2 is used for locking a screw, and can be used for connecting and fixing other parts or components through the cooperation of the screw and the rivet. Secondly, people can set threads on the outer surface of the working part, and then can be matched with nuts to connect and fix other parts.
A rivet for implanting a beveled metal part according to the above description, the method for implanting a beveled surface comprising the steps of:
Step one: a blind hole 11 is formed in advance in the inclined metal member 101 at a position where a rivet is to be implanted, as shown in fig. 3, the diameter d2 of the blind hole 11 is larger than the diameter of the bottom panel 5, smaller than the diagonal line of the implantation end upper panel 4, and the depth of the blind hole 11 is smaller than the height of the implantation end.
Step two: the rivet of the invention is placed in the lower die of the upper die of the press machine, the rivet is supported by a cushion block arranged on the lower die, then the inclined plane metal part 101 is placed in the upper die of the die, and the upper die is positioned, at the moment, the inclined plane metal part is at a certain distance S from the lower die, as shown in fig. 4, the bottom surface of the rivet bottom panel 5 is positioned in the blind hole of the inclined plane metal part 101. The die is a die of the inclined plane metal part 101, a placing hole site for placing rivets is formed in the lower die, the lower die in the die is arranged on a workbench of a press machine, and the upper die in the die is arranged on a stamping head of the press machine.
Step three: the press apparatus is operated to move the upper die plate downwardly in the direction "V" in fig. 4 to rivet the rivet of the present invention to the metal part 101, as shown in fig. 5, which is a schematic view of the rivet being riveted into the beveled metal part. Since the distance H from the hole to the bottom surface of the implantation end is smaller than 2 times the diameter D of the working portion (H < 2D), or the hole is extended to penetrate the implantation end (h=0), the strength of the root portion of the working portion of the rivet is weakened, so that the metal part generates a force on the root portion of the working portion of the rivet after the upper die is pressed down during riveting, and the root portion of the working portion can generate weak bending deformation under the action of the force. Simultaneously, the hardness of this product rivet is greater than the hardness of metal part for the implantation end has kept its bending that can follow the rivet integrally and be difficult for yielding owing to the bending of working portion root, and can laminate better in the blind hole riveting.
If the distance H from the hole on the working portion of the rivet to the bottom surface of the implanted end is greater than 2 times the diameter D of the working portion (i.e., H > 2D), the strength of the root portion of the working portion of the rivet cannot be weakened, and at this time, the rivet is riveted to the metal member 101, which causes deformation of the upper panel 4 and the bottom panel 5 of the implanted end to easily close the annular notch 6, so that the deformed material of the inclined metal member 101 cannot be pressed into the annular notch 6, and the rivet cannot be riveted to the inclined metal member 101.
Step four: and taking the bevel metal component riveted with the rivet out of the die. Therefore, the rivet is in a vertical state, the bottom surface of the rivet is not exposed on the surface of the inclined plane metal part, the inclined plane metal part can be implanted into the rivet, the bottom surface of the rivet is not exposed on the surface of the inclined plane metal part, and the appearance of the riveted rivet of the inclined plane metal part is ensured. The method also solves the limitation that the existing squeeze riveting process is only suitable for planar metal parts, so that the structure of the manufactured product is more colorful, and the industrial manufacturing industry is further developed.
It should be noted that the term "implantation" as used herein also means "riveting" as used herein, and the inclined surface may be an inclined surface or a curved surface with an arc, and the method of implanting the rivet disclosed herein into a metal member with an inclined surface is also applicable to implanting the rivet designed according to the present invention into a metal member with a flat surface.
The above examples of the present invention are merely illustrative of the present invention and are not intended to limit the embodiments of the present invention. And obvious variations or modifications which come within the spirit of the invention are desired to be protected.
