Description
Technical field
The present invention relates to aluminium alloy automobile framework interconnection technique, be specially a kind of explosion type from riveting equipment and method.
Background technology
For the consumption and the emission of automobile wastes amount that reduce motor vehicle fuel, automobile vendors are developing the lightweight automobile always, particularly adopt aluminum alloy materials to replace steel to make car body of aluminum alloy.And the main connecting portion that car body of aluminum alloy connects promptly is the connection of aluminium alloy plate.Because it is little that aluminium alloy itself has resistivity, good heat conductivity, and aluminium material surface forms oxide-film.If require welding procedure corresponding point welding steel plate to need with big electric current of short time and big electrode pressure with the conventional point soldering method, this provides big rigidity and big transformer that big welding current is provided with regard to needing mash welder to have big horn, and for guaranteeing aluminum alloy surface acquisition uniform sheet resistance, need alkali cleaning before the welding.For this reason, external car body of aluminum alloy automobile tends to a kind of novel method of attachment---and riveted joint (self-piercing rivet) replaces traditional spot welding certainly, used 1100 rivets to be connected vehicle body as the A8 of Audi car body of aluminum alloy automobile with 500 solder joints, and the generation aluminium alloy automobile AL2 of Audi that upgrades, complete automobile-used 1500 rivets and no one uses spot welding are as seen from the importance of riveting technology in the modern aluminum alloy automobile is made.Be different from traditional riveted joint from riveting technology, it does not need to rivet preceding boring, two aluminium sheet 3 overlapping being placed in the middle of impact bar 2 and the mould 4 during riveted joint, impact bar 2 applies the head of a power at rivet 5 along sleeve 1, rivet 5 passes the last aluminium sheet 31 of two overlapping aluminium sheets 3 then, and because back side mould 4 effects of lower aluminum sheet 32 make rivet 5 natures separately inner at lower aluminum sheet 32, thereby the mechanical fasteners that reaches self-locking connects, detailed process is shown in Fig. 1 a～Fig. 1 f, traditional mainly is to offer the impact bar impulsive force with cylinder or electric power from riveting technology, the equipment more complicated.
Summary of the invention
The purpose of this invention is to provide a kind of explosion type from riveting equipment and method, offer the bigger impulsive force of impact bar by simple application of force method.
Technical scheme of the present invention is:
A kind of explosion type has sleeve, impact bar from riveting equipment, and described impact bar longitudinal section is I-shaped, impact bar places in the sleeve, is with sleeve to be slidingly matched, and the sleeve upper end is connected with end face, this end face has for impacting bullet by, the hole coaxial with impact bar, sleeve lower ending opening.
Described impact bar lower surface diameter is greater than the rivet head diameter.
Described impact bar lower surface is provided with coaxial with impact bar, identical with rivet head diameter step.
Described sleeve lower end is provided with the end face of perforate, and perforate matches with step.
Explosion type of the present invention is from clinching method, and concrete steps are:
1) rivet is packed into sleeve, the impact bar head gos deep into the sleeve compression rivet, and the impact bar afterbody submerges in the ail gun head skirt, and rivet axial centre, impact bar axial centre, mould axial centre are at same straight line in the impact process;
2) pull the ail gun trigger and trigger bullet, the ail gun inner carrier impacts the impact bar of the ail gun that submerges because the impact of gunpowder travels forward, and impact bar impacts rivet again, and rivet forms self-locking and is fastenedly connected owing to the effect of impulsive force and following mould in aluminium sheet.
Advantage of the present invention and beneficial effect are as follows:
1, the present invention does not have complicated control system, and the parts that need high accuracy processing seldom utilize it can make things convenient for, finish at an easy rate from the riveted joint process, and do not need power supply.The evidence explosion type has good frying in shallow oil from riveted joint and cuts performance, cross tensile property and impact property, and its fatigue strength is in circulation 10
7After reach 3KN, be three times of traditional spot welding.Need low relatively fund input and operating costs with blast as the riveted joint certainly of impacting power, service life of equipment is long, and easy-maintaining especially is fit to motor vehicle repair and uses.Also can be fit to large-scale industrial production through after the industrialization design.
2, to adopt the longitudinal section be I-shaped impact bar for impact bar of the present invention, can reduce frictional resistance.
Description of drawings
Fig. 1 a～Fig. 1 f is prior art aluminium alloy riveted joint process schematic diagram.
Fig. 2 is the one embodiment of the invention structural representation.
Fig. 3 is the another embodiment of the present invention structural representation.
The specific embodiment
The structure of the main application of force equipment of the present invention and each position such as Fig. 2～shown in Figure 3, mainly comprise sleeve 1, impact bar 2, last aluminium sheet 31, lower aluminum sheet 32, mould 4, rivet 5, impact bullet 6, cavity 7 etc.
1, the longitudinal section is that I-shaped impact bar 2 can have dual mode, and corresponding sleeve 1 also is respectively two kinds.As shown in Figure 2, impact bar 2 end diameter in the sleeve 1 bear blast impulse power too much greater than the rivet head diameter in big surface of aluminum plate scope, the upper and lower aluminium sheet 31,32 thereby assurance impact back rivet head is just in time submerged.As shown in Figure 3, the end diameter of sleeve 1 just in time equals the rivet head diameter, and a step 21 is arranged, and just in time bears than the big extra power of riveted joint rivet 5, thereby make power excessive in the blast process pass to sleeve, guarantee the rivet head upper and lower aluminium sheet 31,32 that just in time submerges.
2, the explosive payload of impacting bullet 6 can be selected according to the impulsive force size of actual conditions needs.
3, require rivet 5 axial centre, impact bar 2 axial centre, mould 4 axial centre at same straight line in the impact process.
The use of the said equipment is:
1, this example adopts common ail gun and nailing bullet that blast impulse power is provided;
2, rivet is packed in the cavity 7 of sleeve 1, impact bar 2 heads go deep into sleeve 1 compression rivet 5, and impact bar 2 afterbodys submerge in the ail gun head skirt 1.
3, pull the ail gun trigger and trigger impact bullet 6, the ail gun inner carrier impacts the impact bar 2 of the ail gun that submerges because the impact of gunpowder travels forward, impact bar impacts rivet 5 again, rivet 5 forms self-locking and is fastenedly connected owing to the effect of impulsive force and following mould 4 in upper and lower aluminium sheet 31,32.
4, rivet the impact bullet that changes the outfit behind what a position, rivet once more.
