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. 6, the utility model provides a kind of composition metal, is according to following when makingMode is carried out:

First, most convex body 13 Hes have been processed to form on a surface 11 of one first metallic object 10 to be shapedMost chases 14; The first metallic object 10 in this step can be the gold that the hardness such as copper alloy or stainless steel is highBelong to made plate or the column of material, this first metallic object 10 has a first surface 11 and (or is called for short tableFace) and be formed on a second surface 12 of first surface 11 behind sides. The processing that is wherein shaped can be rolling, punchingPressure, laser, the mode such as in-molded form, and the present embodiment explains with rolling processing mode, when firstMetallic object 10 is transferred band while sending out, utilizes the casting lug thereon of the surperficial institute of roller (scheming not shown) moulding and recessedGroove imposes rotary rolling mill to first surface 11, can on first surface 11, be formed with successional many simultaneouslyNumber convex body 13 and most chase 14 (as shown in Figure 1).

Wherein, top 131 faces of deciding what is right and what is wrong of each convex body 13 can be outwardly protrude and upper width to be less than bottom wideThe kenels such as trapezoidal (as shown in Figure 1), the handstand V-arrangement of degree, straight plane or the semicircle protruded outwardly, top131 also can be towards the concave arc (scheming not shown) sinking into. Again, the face shaping of each convex body 13 can be rectangle(as shown in Figure 4), cross (as shown in Figure 9), triangle (as shown in figure 10), circular (as Figure 11 instituteShow), the kenel such as hexagon (as shown in figure 12). In addition, each convex body 13 is except can be as in previous embodimentVarious geometries outside, can be also non-geometry or irregularly shaped.

Wherein each chase 14 can be the setting of horizontal, longitudinal or oblique interval, to form between each chase 14There are most strip convex bodys 13 (as shown in Figure 8); Each chase 14 also can be horizontal and vertical cross-over configuration orTwo diagonal cross configurations, to be formed with most convex bodys 13 (as Fig. 4 and extremely figure of Fig. 9 between each chase 14Shown in 12); Or each chase 14 also can be waveform, to be formed with most waveforms between each chase 14Convex body 13 (as shown in figure 13).

Secondly, with one first pressing element 5, each this convex body 13 is imposed to plastic deformation, thereby make this chase 14Root width W 1 is greater than the top width W2 of this chase 14; Refer to shown in Fig. 1 to Fig. 3 this enforcementRoutine for the top 131 of each convex body 13 is pressed with a first flat pressing element 5, and then make each convex body 13Produce plastic deformation, thereby make the root width W 1 of chase 14 be greater than the top width W2 of chase 14.

Then, by overlapped one second metallic object 20, on this surface 11 of this first metallic object 10, this is 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.

Finally, with one second pressing element 6, this first metallic object 10 being imposed to crimping with this second metallic object 20 addsWork, thus make this second metallic object 20 and each this convex body 13 and respectively the mutual build-in of this chase 14 be combined. PleaseConsult shown in Fig. 5 to Fig. 6, the second pressing element 6 wherein can be a crimp or a roller set 60, itsCentral roll wheels 60 comprise a upper roll wheel 61 and are configured in a lower roll wheel 62 of position under upper roll wheel 61,Wherein crimping processing can cold-working or hotwork mode carry out, will complete aforementioned the first metal that repeatedly connects techniqueBody 10 and the second metallic object 20 are sent between upper roll wheel 61 and lower roll wheel 62 and are carried out rolling processing, due toThe hardness of two metallic objects 20 is lower than the hardness of the first metallic object 10, thereby in the pressure through each running roller 61,62After connecing, will make the second metallic object 20 and each convex body 13 and each chase 14 form the rivet clasp structure of mechanical type interlockAnd build-in combination.

Shown in Fig. 6, the prepared composition metal of aforementioned preparation method, comprises one first metallic object10 and one second metallic object 20, the first metallic objects 10 there is a first surface 11,11 one-tenth of first surfacesShape has most convex bodys 13, and is formed with most chases 14 between each convex body 13, and chase 14 is away fromThe position on one surface 11 has a root width W 1 and has a top in the position of contiguous first surface 11Width W 2, root width W 1 is greater than top width W2; The second metallic object 20 hardness are less than the first metalThe hardness of body 10, the second metallic object 20 be crimped on first surface 11 and with each convex body 13 and each chase14 form the rivet clasp structure of mechanical type interlocks and build-in combination.

Refer to shown in Fig. 7, 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 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. 3).

In addition composition metal of the present utility model, wherein each convex body 13 of the first metallic object 10 and each chase,14 except can be the one side of the various embodiments described above arranges, also can be at the first surface of the first metallic object 10 11All be provided with aforementioned convex body 13 and chase 14 with second surface 12.

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.
