Abstract

a) punching and pressing the metal rivet from the metal material side into the upper electrode; And b) welding the welding protrusions to the metallic material by applying an electric current while pressing the head of the metal rivet with the upper electrode. In the step a), the metal rivet is pressed so that the welding projection can be brought into contact with the metal material, and in the step b), the metal projection is further press-fitted while the welding projection is melted and collapsed.

Description

[0001] METHOD FOR JOINING DISSIMILAR MATERIALS [

The present invention relates to a dissimilar member, in particular to a method of joining between a composite material and a metallic material. The present invention is the result of research carried out by the Ministry of Commerce, Industry and Energy and the Korea Institute of Industrial Technology Development in an effort to foster an economic cooperation industry.

The key keywords of technology related to vehicle body parts in recent years are lighter weight and higher strength. There is a high demand for lighter vehicle parts while ensuring the strength and stability of conventional steel parts.

Lightweight materials include light metals such as aluminum and magnesium or polymer composites such as carbon fiber reinforced plastic (CFRP). When lightweight materials are applied to the manufacture of vehicle components, joining with other members, particularly steel members, is a problem.

Mechanical joining, bonding, Friction Spot Welding, etc. may be used for bonding between the different members. SPR (Self Piercing Rivet) can be used for mechanical bonding.

SPR is a very good means for joining dissimilar members, but the tip of the rivet after punching leaves a protruding area on the backside. For mechanical bonding, the tip of the rivet spreads in the form of π in the left-right direction, and this portion protrudes above the joint portion.

The above SPR can not be used when exposed to the joint and the outside. In addition, SPR is effective for joining steel and light metal, but cracking occurs at the joints of the composite material when the steel and the polymer composite are bonded, or the appearance defect is problematic.

SUMMARY OF THE INVENTION The present invention is based on the recognition of the prior art as described above, and aims to provide an improved method of joining heterogeneous members which is useful for bonding between a metal material and a plastic composite material.

Another object of the present invention is to provide a dissimilar member joining method in which joining can be performed quickly and easily, and the joining state between the dissimilar members can be stably maintained after the joining is completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components or parts are denoted by the same reference numerals as much as possible for convenience of description.

It should be understood that the drawings described below are somewhat exaggerated for convenience of description.

1 and 2, a metal rivet 10 used in joining a dissimilar member according to an embodiment of the present invention will be described.

As shown in Figs. 1 and 2, the metal rivet 10 has a head 11 and a body 12 extending from the head 11.

The upper surface of the head 11 is flat and the welding projection 11a is formed on the lower surface. The flat upper surface allows the punching force to be effectively transmitted, and can be arranged flat with the object to be welded after being bonded to the object to be welded, thereby improving the appearance at the joint.

The welding protrusions 11a of the head 11 may be formed continuously in the circumferential direction on the lower surface or may be formed in plural numbers. The welding protrusion 11a is for welding the rivet 10 to the object to be welded, and has a function similar to the projection of the bolt or nut for projection welding.

The bottom surface of the welding projection 11a is formed to be inclined downward in the direction of the central axis of the metal rivet 10. [ The lower metal member 1 around the rivet 10 is formed to be curled in the punching direction when punching the metal rivet 10 So that the heat of resistance at this portion can be concentrated.

A concave groove 13 is formed along the periphery of the head 11 at a portion extending from the welding projection 11a to the body 12. [ The concave groove 13 allows the melt of the welding protrusion 11a to flow inwardly without exiting outward during the welding process so that a sound weld can be generated.

The body 12 extends from the head 11 and has a front body 12 at a position opposite the head 11. [ An inner hole 12a is formed from the tip end 12c toward the head 11 side so that the body 12 can be regarded as a hollow tube.

The inner peripheral surface of the body 12 on the tip end 12c side is formed to be tapered toward the tip end 12c. The tapered tip portion allows the rivet (10) to be pressed into the welding object more easily by the punching force.

A plurality of fixing protrusions 12b are formed on the outer circumferential surface of the body 12 in the circumferential direction. The fixing protrusions 12b are formed in a circular shape along the circumference with respect to the longitudinal central axis of the body 12. [ A spiral protrusion can be considered, but a circular protrusion is preferred in consideration of the fixing force at the interface between the rivet 10 and the object to be welded, or resistance to the deviation of the rivet 10. [

A method of joining the metal material and the polymer composite material using the metal rivet 10 according to the embodiment will be described with reference to FIGS. 3 to 5B.

Adhesion step (S1)

The adhesive is applied to the overlapping region between the metal material (1) and the composite material (2) to be bonded. As adhesives, structural adhesives or other thermosetting adhesives are used. Adhesive may be applied in addition to the area to be bonded.

The strength of the joint between the metallic material 1 and the composite material 2 can be improved by using an adhesive in addition to the rivet 10 to be described later.

The riveting step (S2)

4A and 4B, the metal material 1 and the composite material 2 coated with the adhesive are disposed between the upper and lower electrodes 4a and 4b and the metal rivet 10 is punched to form the metal material 1, And the composite material (2).

As shown in FIG. 5A, electrodes 4a and 4b are used for punching and press-fitting of the metal rivet 10.

The upper electrode 4a is disposed on the metal member 1 side and is movable up and down. In the case of using a separate punching machine, the two steps of punching and welding must be performed. For the sake of process efficiency, the rivets 10 are punched using the electrodes 4a and 4b and successively welded successively.

As shown in Figs. 5A and 5B, the lower electrode 4b is disposed on the composite side in the punching and welding process. The interior of the rivet 10 is formed into a hollow cylindrical shape so that the metallic material 1 and the composite material 2 which are separated by the metallic material 1 and the composite material 2 are separated.

The upper and lower electrodes 4a and 4b are pressed by a pressing device (not shown). The lower electrode 4b may be rotated by a robot arm or other means for discharging the scrap. The pressurizing device is connected to the holder 3 of the upper and lower electrodes 4a and 4b.

The holes for inserting the rivet 10 are not previously formed in the metal material 1 or the composite material 2 during the process of press-fitting the rivet 10. [ The rivet 10 penetrates the metal material 1 and is press-fitted into the composite material 2 by the punching force by the upper electrode 4a.

It is important to select the position where the rivet 10 is punched. According to the embodiment, the rivet 10 is punched on the side of the metal material 1. [ When the rivet 10 is punched on the side of the composite material 2, cracks may occur on the joint of the composite material 2, which may cause defective joining. Therefore, in this case, it will be necessary to pre-hole the composite material side for insertion of the rivet 10 in advance.

The punching force is adjusted so that the rivet 10 is pressed into the metal material 1 and the composite material 2 so that the welding protrusion 11a of the head 11 can be brought into contact with the metal material 1. [ By punching, the rivet 10 completely passes through the metal material 1, and its tip end 12c almost reaches the back surface of the composite material 2. [

In step S2, the scrap of the metal material 1 and the composite material 2 is in a substantially separable state even if they are not separated or completely separated, and the scrap is completely separated by the pressure welding in step S3.

A device for feeding the rivet 10 as in a punching machine and guiding it in the punching process can be used so that the upper electrode 4a can punch and press the rivet 10 easily.

Rivet pressing / piercing / welding step (S3)

As shown in FIGS. 4C and 5B, after the rivet 10 is first press-fitted into the objects 1 and 2 to be joined by punching the rivet 10 with the upper electrode 4a, The welding is performed after the rivet 10 is secondarily pressed into the welding object 4a through the welding object 1, 2.

Step S3 is a step of pressing the rivet 10 to make the upper surface of the flat head 11 horizontal with the metallic material 1 and welding the projections 11a to the metallic material 1 to obtain the bonding strength.

4B, the head 11 of the metal rivet 10 is brought into contact only with the metal member 1 and the welding projection 11a after the primary rivet 10 is fully inserted. In this state, when current is supplied while pressing the head 11 to the upper electrode 4a, resistance heat is generated at the contact portion between the welding protrusion 11a and the metal material 1, and the welding protrusion 11a is melted and collapsed.

The pressing force of the rivet 10 by the upper electrode 4a in the step S3 must be set so that the rivet 10 can pass completely through the composite 2. [ The composite material 2 can be easily torn because the composite material 2 is almost completely cut off by the rivet 10 and is less ductile than the metallic material 1 in the step S2.

The current and the pressing force supplied from the upper electrode 4a to the rivet 10 need to be adjusted so that melting and collapse of the welding projection 11a can occur at an appropriate time. If the pressing force is larger than the collapse of the welding projection 11a, the resistance heat may not be concentrated on the contact surface between the welding projection 11a and the metal member 1. [

In the embodiment, the step of punching the rivet 10 from the metal material 1 side to join the metal material 1 and the composite material 2 is also advantageous in the step S3. Although the body 12 of the rivet 10 is in contact with the metal material 1, the tip end thereof is in contact with the composite material 2 and only the welding protrusion 11a is in contact with the metal material 1 at the head 11 , The current can be concentrated on the welding projection 11a at the time of current supply.

The welding portion A is formed on the contact surface between the welding protrusion 11a and the metallic member 1 after the welding in the step S3 and the scrap is stored in the receiving portion B of the lower electrode 4b as shown in Figures 4C and 5B. do. The scrap stored in the housing portion B can be taken out by rotating the lower electrode 4b or using a magnetic member.

The adhesive curing step (S4)

Step S4 is a step of curing the thermosetting adhesive previously applied before joining the metal material 1 and the composite material 2. [

The parts with the metal material (1) and the composite material (2) joined together can be delivered to the car maker in the form of a completed assembly, but in some cases they can be delivered to the car maker in the state of being joined. In the automobile maker, the finished assembly can be cured by heat-treating the entire assembled part after performing the necessary processing or assembly for the assembled parts.

In this case, by fixing the metal material 1 and the composite material 2, which are bonded to each other with the adhesive according to the embodiment, by the rivet 10, it is possible to prevent the tolerance from occurring in the transportation process, 2, the rivet 10 can be removed by punching with a strong force.

On the other hand, an excellent bonding force can be obtained between the metal material 1 and the composite material 2 by the curing of the adhesive, the welding between the welding protrusions 11a and the metal material 1, and the releasing resistance by the tip 12c of the rivet 10, It is possible to prevent defective joining such as cracks generated on the side of the composite material 2 by press-fitting the rivet 10 on the side of the metallic material 1. [

6A and 6B, according to another embodiment, in addition to the upper metal member 1 and the composite member 2, the lower metal member 1-1 is laminated on the composite member 2 side, can do.

The upper metal member 1 and the composite member 2 are stacked and the metal rivet 10 is punched out from the upper metal member 1 side so as to completely penetrate them. The length of the metal rivet 10 is longer than the thickness of the upper metal member 1 and the two layers of the composite member 2 and the tip end 12c of the metal rivet 10 after the penetration is partially exposed on the back surface of the composite member 2.

Another metal material 1-1 is adhered to the lower surface of the composite material 2 bonded to the upper metal material 1 by the metal rivet 10 so that the gap between the lower metal material and the composite material The metal rivet 10 is pressed to the upper electrode 4a and the lower metal member 1-1 is pressed to the lower metal electrode 4b through the upper electrode 4a and the rivet 10 The electric current is concentrated on the contact surfaces between the welding projections 11a and the upper metal member 1 and between the tip 12c of the rivet 10 and the lower metal member 1-1 so that the corresponding region melts And welding is performed.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention as set forth in the following claims.
