Embodiment 1

[0065] In one embodiment, the structure of the rivets used in the drill riveting connection of the present invention is as follows: figure 1 As shown, it includes a core rod 1 and a nail cap 2, wherein the structure of the core rod 1 is as figure 2 As shown, the shape of the head 11 of the core rod 1 is a cone, which is used to turn the connected workpiece to reduce the resistance of piercing the workpiece; the cross section of the tail 12 of the core rod 1 is hexagonal, octagonal Polygonal or circular with anti-slip teeth, used to cooperate with the sleeve or jaw connected to the drive motor, and transmit torque to the rivet head (that is, the head of the mandrel) when drilling and riveting; the middle part of the mandrel is provided with The breakpoint ring groove 13, after the riveting is completed, the core rod 1 is broken at the breakpoint ring groove 13.

[0066] exist figure 1 It can be seen in the figure that the nail cap 2 includes a cap head 21 and a cap tube 22, ...

Embodiment 2

[0071] In this embodiment, the structure of the rivets used in the drill riveting connection of the present invention is as follows: Figure 9-11 as shown, Figure 9 is the front view of the rivet, Figure 10 sectional view for the front view of the rivet, Figure 11 Isometric view of a rivet. In this embodiment, the rivet includes a mandrel 1 and a nail cap 2, wherein a blind hole 111 is opened in the head 11 of the mandrel 1 in the axial direction, and the blind hole 111 can accommodate sheet material during penetration. , the outer peripheral wall of the head 22 is symmetrically provided with two cutouts 112, the cutouts 112 open upward from the bottom of the head 11, the cutouts 112 communicate with the blind hole 111, this arrangement makes all The head 11 fully accommodates the plate material as much as possible, and the two cuts 112 divide the lower end of the head 11 into two cutting point edges, which reduce the contact between the rivet and the connected workpiece...

Embodiment 3

[0077] In this embodiment, the rivet of this embodiment is a single-drum rivet structure, and its specific structure and riveting process are as follows: Figure 19-22 as shown, Figure 19 It is a schematic diagram of the state when the rivet rotates and reaches the workpiece 3 to be connected, Figure 20 It is a schematic diagram of the state where the rivet is stirring and cutting through the connected workpiece 3, Figure 21 It is a schematic diagram of the state of the single-drum locking structure produced by the cap tube 22 of the rivet being squeezed and deformed when the force in the opposite direction is applied to the mandrel 1 and the nut 2 of the rivet. Figure 22 It is a schematic diagram of the state where the core rod 1 is continuously pulled upwards and broken at the ring groove 13 at the breaking point. exist Figure 21 It can be seen from the figure that during the riveting process, the cap tube 22 of the nail cap is deformed to form a single-drum locking...

Abstract

The invention provides a hot-melting drill-rivet rivet and a drill-rivet connection method. The hot-melting drill-rivet rivet comprises a core bar and a rivet cap. The head portion of the core bar isused for conducting drilling on a connected workpiece. The tail portion of the core bar is used for being connected with a sleeve or a clamping jaw of a drive motor and transmitting twisting force tothe head portion of the core bar during drilling and riveting. The rivet cap is arranged on the periphery of the core bar in a sleeving manner. In the riveting process, the rivet cap can be compressedor extended and expanded and is used for being riveted with the connected workpiece. The invention further provides a hot-melting drill-rivet connection method. The core bar of the rivet can transmittorque and conduct drilling, and resistance of workpiece impaling is reduced; the rivet cap arranged outside the core bar can be compressed and press the connected workpiece and an extension layer ofthe connected workpiece, and therefore the rivet can have a double-bearing structure and can be prevented from being wiggled by the connected workpiece after riveting; and drilling and riveting can be compounded into a whole and be completed in one step, the riveting working procedure is greatly shortened, efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of riveting, in particular to a hot-melt drill rivet and a drill riveting connection method. Background technique [0002] The joining technology of metal materials is widely used in the industrial field. There are many kinds of joining techniques for metal materials, such as: electric welding, resistance spot welding, rotary friction spot welding, solid-state riveting, pull riveting, rotary friction pull riveting, self-piercing riveting and rivetless riveting, etc. [0003] Both self-piercing riveting technology and rivetless riveting technology belong to mechanical connection technology. They can overcome the shortcomings of traditional fusion welding technology in connecting light non-ferrous metal alloy materials, dissimilar plates and plates coated with protective layers. They have been used in automobile production. be widely used. Self-piercing riveting is a cold deformation connection process. When...
