Abstract
The invention discloses a connecting method for dissimilar metal. The connecting method comprises the step S1 of material selection, the step S2 of positioning and clamping, the step S3 of puncture, the step S4 of riveting and the step S5 of forming and shaping. The step S4 is characterized in that a leg part of a rivet also begins expanding outwards with flowing of a lower-layer plate material into a concave die; due to the shape of the concave die, an annular part of the rivet is formed to enter the lower-layer plate material, and a leg end part of a rivet tube is opened towards peripheries while being inlaid into the plate material to form a rivet buckle, so that a firm mechanical interlocking structure is formed between upper and lower plate materials; a puncher pin pressure is relieved and a return stroke is started; and during stamping, factor parameters which can influence rivet quality include a rivet model, riveting force, pre-compressing force and riveting time. The connecting technological method for the dissimilar metal disclosed by the invention is normative and uniform and has the advantages that productive capability is stable; and production efficiency is increased.

S2, position, clamp；
Plate, mould, drift are positioned, with blank holder by sheet material clamping；
S3, puncture；
Being pressed into described upper strata plate with rivet described in punch holder, when described rivet penetrates described upper strata plate, described rivet leg is equivalent to a drift, and the most described rivet is also partially through described lower floor plate；
S4, riveting；
Along with described lower plywood stream enters die, described rivet leg also begins to expand outwardly, die shape forces described rivet annular section to enter in described lower floor plate, formation rivet is opened to periphery during being embedded into plate in described rivet pipe lower limb end, thus between upper and lower plate, form a firm mechanical interlock, the lax also backhaul of punch pressure, in punching course, described rivet model is 5*6mm, CSR-H4, described lower mould model is DG09-160, and the described riveting time is 1.1S, described pretightning force is 5KN, and described rivet force is 43KN；
S5, molding, sizing；
Described rivet is filled by upper and lower plate and completes sizing in described mould.
It is an advantage of the current invention that:
The most this Joining Technology is cold Joining Technology, it is adaptable to multilamellar, polytype sheet material connect；
The most this Joining Technology operation completes rapidly (1-2 second), can meet production demand；
The most this Joining Technology riveting point intensity is the highest, and the life-span is long.

Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are for illustrating that the present invention is not limited to limit the scope of the present invention.The implementation condition used in embodiment can do adjustment further according to the condition of concrete producer, and not marked implementation condition is usually the condition in normal experiment.
A kind of method of attachment of dissimilar metal, described method of attachment comprises the following steps:
S1, selection
Choose plate, as it is shown in figure 1, selected upper strata plate 1 is aluminum component, material be STJLR 50:5009 (RC5754)+
STJLR 50:5002 Type C+STJLR.50.5060, thickness of slab 1.5mm；Lower floor's plate 2 is ironware, and material is STJLR 50.5172 MS2+STJLR 50.5041 Z100, and thickness of slab is 2.5mm, and green part 3 is SPR rivet；
S2, position, clamp；
As shown in Figure 3, Figure 4, selected plate is positioned, clamps, plate, mould, drift are positioned, with blank holder by sheet material clamping；
S3, puncture；
As it is shown in figure 5, be pressed into upper strata plate with punch holder rivet, when rivet penetrates upper strata plate, rivet leg is equivalent to a drift, and rivet is also partially through described lower floor plate simultaneously；
S4, riveting；
As shown in Figure 6, along with lower plywood stream enters die, rivet leg also begins to expand outwardly, die shape forces rivet annular section to enter in lower floor's plate, formation rivet is opened to periphery during being embedded into plate in rivet pipe lower limb end, thus between upper and lower plate, form a firm mechanical interlock, the lax also backhaul of punch pressure, the factor parameter affecting rivet quality in punching course includes rivet model, rivet force, pre-pressing force, the riveting time, rivet model is 5*6mm, CSR-H4, lower mould model is DG09-160, the riveting time is 1.1S, pretightning force is 5KN, rivet force is 43KN；Molding, sizing, as shown in Figure 7, Figure 8, rivet is filled by upper and lower plate and completes sizing in mould.
