Detailed description of the invention

Relevant detailed description of the present utility model and technology contents, coordinate graphic being described as follows, but institute's accompanying drawingFormula only provide with reference to and explanation use, be not used in addition limitr of the utility model.

Refer to shown in Fig. 1 and Fig. 4, the utility model provides a kind of composite metal structures, is to comply with when makingFollowing manner is carried out:

First, be formed with most convex bodys 13 on a surface 11 of one first metallic object 10, respectively should be formed onMost chases 14 between convex body 13 and a recessed groove 131 that is formed on each this convex body 13; Refer toShown in Fig. 1 and Fig. 2, it is high that the first metallic object 10 in this step can be the hardness such as copper alloy or stainless steelMade plate or the column of metal material, this first metallic object 10 have a first surface 11 (or letterClaim surface) and be formed on a second surface 12 of first surface 11 behind sides. Wherein be shaped processing can be rolling,Punching press, laser, the mode such as in-molded form, and the present embodiment explains with rolling processing mode, whenOne metallic object 10 is transferred band while sending out, utilizes the groove, protruding of the surperficial institute of roller (scheming not shown) mouldingGo out piece and raised line first surface 11 is imposed to rotary rolling mill, can on first surface 11, be formed with simultaneously and connectMost convex bodys 13, most chase 14 and most recessed groove 131 of continuous property.

Wherein, recessed groove 131 faces of deciding what is right and what is wrong of each convex body 13 can be a V font, and recessed groove 131 is darkDegree D1 is greater than the depth D 2 (as shown in Figure 2) of chase 14. Again, the face shaping of each convex body 13 can be squareShape (as shown in Figure 1), cross (as shown in Figure 7), triangle (as shown in Figure 8), circular (as Fig. 9 instituteShow), the kenel such as hexagon (as shown in figure 10). In addition, each convex body 13 is except can be as in previous embodimentVarious geometries outside, can also be non-geometry or irregularly shaped.

Wherein, each chase 14 can be horizontal, longitudinal or oblique interval and arranges, with shape between each chase 14Become to have most strip convex bodys 13 (as shown in Figure 6); Each chase 14 also can be horizontal and vertical cross-over configurationOr two diagonal cross configurations, to be formed with most convex bodys 13 (if Fig. 1, Fig. 6 are to figure between each chase 14Shown in 10); Or each chase 14 also can be waveform, to be formed with most waveforms between each chase 14Convex body 13 (as shown in figure 11).

Secondly, by overlapped one second metallic object 20, on this surface 11 of this first metallic object 10, this is the years oldThe hardness of two metallic objects 20 is less than the hardness of this first metallic object 10; The second metallic object in this step20 can be the low made plates of metal material of hardness such as aluminium alloy, magnesium alloy, almag or copper alloy,The hardness of the second metallic object 20 is less than the hardness of the first metallic object 10, and the second metallic object 20 correspondences are repeatedly connectOn the first surface 11 of the first metallic object 10 (as shown in Figure 3).

Then, with a pressing element 6, this first metallic object 10 and this second metallic object 20 are carried out to crimping processing,Thereby with order respectively this convex body 13 produce plastic deformation and make the root width W 1 of this chase 14 be greater than this chase14 top width W2 allows this second metallic object 20 and each this convex body 13, each this chase 14 and simultaneouslyRespectively these recessed groove 131 build-in combinations. Refer to shown in Fig. 3 to Fig. 4, pressing element wherein can be a pressure welding moldTool or a roller set 60, wherein roller set 60 comprises a upper roll wheel 61 and is configured under upper roll wheel 61One lower roll wheel 62 of position, wherein crimping processing can cold-working or hotwork mode carry out, aforementioned by completingThe first metallic object 10 and the second metallic object 20 that repeatedly connect technique are sent between upper roll wheel 61 and lower roll wheel 62Row rolling processing, because the hardness of the second metallic object 20 is lower than the hardness of the first metallic object 10, through each rollerAfter the crimping of wheel 61,62, will make each convex body 13 produce plastic deformation, thereby make the root width of chase 14W1 is greater than the top width W2 of chase 14, allows the second metallic object 20 and each convex body 13, each chase simultaneously14 and each recessed groove 131 form the rivet clasp structure of mechanical type interlock and build-in combination.

Shown in Fig. 4, aforementioned preparation method can make a kind of composite metal structures, and it comprises oneOne metallic object 10 and one second metallic object 20, the first metallic objects 10 have a first surface 11, firstSurface 11 is formed with most convex bodys 13 and is formed on the most chases 14 between each convex body 13, each convex body13 are respectively equipped with a recessed groove 131, and chase 14 has a root width away from the position of first surface 11W1 and have a top width W2 in the position of contiguous first surface 11, root width W 1 is greater than topWidth W 2; The second metallic object 20 hardness are less than the hardness of the first metallic object 10, and the second metallic object 20 is pressedBe connected on first surface 11 and form mechanical type with each convex body 13, each chase 14 and each recessed groove 131 and stingThe rivet clasp structure of closing and build-in combination.

Refer to shown in Fig. 5, first metallic object 10 of the present embodiment is to become at the zone line of each chase 14The shape face guiding structural 15 triangular in shape of deciding what is right and what is wrong, is formed with respectively a guide ramp in guiding structural 15 both sides151, this guide ramp 151 has guiding the second metallic object 20 can invade each chase 14 and build-in easilyIn conjunction with, and can effectively reduce the second metallic object 20 in flow process because Plastic Flow path has some setbacksAnd produce the problems such as space, and then can promote the consolidation strength of the second metallic object 20 and the first metallic object 10.

Refer to shown in Figure 12, wherein the recessed groove 131 of each convex body 13 is decided what is right and what is wrong face except can be above-mentioned each realityExecuting exception, can be also a handstand M font as the present embodiment, and the depth D 3 of recessed groove 131 be less than chase14 depth D 2 is so easy to make both sides after the second metallic object 20 pressurizeds are invaded in recessed groove 131Wall produces and extends out formula plastic deformation and build-in combination. It is recessed that 13 of each rectangle convex bodys in Figure 13 offer connectionFall into a groove 132 of groove 131, so also have and make each sidewall easily produce the effect that is equal to that extends out formula plastic deformationReally.

Refer to shown in Figure 14, wherein the first metallic object 10 is except can be the dull and stereotyped kenel of the various embodiments described aboveOutward, can be also a cylinder as the present embodiment, form most convex body 13 Hes at cylindrical circumferential surfaceMost chases 14, wherein the root width W 1 of chase 14 is greater than top width W2 (consulting Fig. 4).

In addition composite metal structures of the present utility model, wherein each convex body 13 of the first metallic object 10 and each,Chase 14, also can be at the first table of the first metallic object 10 except can be the one side of the various embodiments described above arrangesFace 11 and second surface 12 are all provided with aforementioned convex body 13, chase 14 and recessed groove 131. Again, this realityIn manufacturing process, can implement the rollings processing of most times with novel composite metal structures, use reach thinType effect.

Certainly, the utility model also can have other various embodiments, do not deviate from the utility model spirit andIn the situation of essence, those of ordinary skill in the art can make various corresponding changes according to the utility modelAnd distortion, but these corresponding changes and distortion all should belong to the protection domain of the utility model claim.
