Abstract
The present invention relates to a rivet-free metal riveting method. Two metal plates to be riveted are prepared; a plurality of plate holes with the same hole diameter are stamped on one plate by a pressing machine; the plate holes are uniformly distributed and are arranged in rows; ratio of the diameter of each plate hole to plate thickness is 1: 1 to 1: 2; holes at the upper row and the holes at the lower row are alternatively distributed; then, the plate holes are trimmed to get rid of burrs on the periphery, convex edges and concave edges; bulges of which the number is same with the number of the plate holes of the metal plate are stamped on the other plate by the pressing machine; the distribution of the bulges is consistent with the distribution of the plates holes; the outer diameter of each bulge is matched with the outer diameter of each plate hole; distance among the bulges keeps consistent with distance among the plate holes; the deviation of the mutual matching distance of the bulges and the plate holes is controlled in the range of 0 to +/-0.05. The plate holes and the bulges on the two metal plates are aligned; the height of die sinking and die height are adjusted, and then the two plates are riveted by the pressing machine. The present invention has the advantages that no rivet is used; spot welding machines or mechanical hands are not used for weld, and thus, the present invention can reduce cost and improve efficiency and has beautiful molding, fastness, good adaptability and strong reliability. The present invention is suitable for the riveting of multitudinous small plates of which plate thickness is smaller than 4mm in automobile industry and other industry.
Description
Technical field
The present invention relates to a kind of rivet-free metal riveting method.
Background technique
In current automobile and wireless industry, sheet metal structural is commonplace.Sheet metal structural relates to the connection of two pressed plates, with spot welding machine or mechanism hand two pressed plates is connected together usually.Secondly with rivet two pressed plates are linked together.
In existing riveting process, with spot welding machine or mechanism hand two pressed plates are connected together, we claim that it is a rivet welding.Rivet welding has the advantages that moulding is attractive in appearance, efficient is high, and its shortcoming is that cost is relatively more expensive.
Next is with rivet its two pressed plates to be riveted together, and this riveted joint mode is more firm, and its shortcoming is not attractive in appearance for being shaped, and the head and the root of riveted joint back pulling rivet all go out to serve, and like this, pressed plate is put injustice, can not use screw lock.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, provide a kind of and reduce cost, raise the efficiency, moulding is attractive in appearance, and firmly is suitable for the no rivet method of good reliability.
Technical solution of the present invention is: get two sheet metals to be riveted, with press machine on a sheet metal, stamp out the aperture identical, be evenly distributed and divide several plate holes of arranging and putting, ratio is 1: 1～1: 2 between the diameter of said plate hole and the thickness of slab, and two adjacent rounds are dislocatedly distributed, repair plate hole again, remove plate week burr, chimb and concave edge; Stamp out on another piece sheet metal with press machine that sheet metal upper plate number of perforations with the band plate hole is identical, projection consistent and that external diameter cooperates with plate hole distributes, distance between the said projection and the distance between the plate hole are consistent, and the Deviation Control of the two distance that cooperatively interacts 0～± the 0.05mm scope in; Plate hole and projection on two sheet metals are aligned, adjust die sinking and die height, both are riveted together with press machine.
According to above-mentioned rivet-free metal riveting method, said sheet metal is low carbon steel or aluminum alloy or copper alloy plate.
According to above-mentioned rivet-free metal riveting method, when described sheet metal was low carbon steel, the pressure of press machine was 265～290Mpa when punching press or pull and stretch; When described sheet metal was aluminium alloy plate and copper alloy plate, the pressure of press machine was 240～265Mpa when punching press or pull and stretch.
According to above-mentioned rivet-free metal riveting method, when sheet metal was low carbon steel, the pressure of press machine was 155～170Mpa during riveted joint; When sheet metal was aluminium alloy plate and copper alloy plate, the pressure of press machine was 140～155Mpa during riveted joint.
The present invention under rivet and the situation without the welding of spot welding machine and mechanism hand is riveted together two stamping part not having.Therefore, can reduce cost, raise the efficiency, moulding is attractive in appearance, and firmly is suitable for good reliability.Be adapted at the riveted joint production in enormous quantities of the sheet material of thickness of slab below 4mm of automobile industry and other industry aspects.

Embodiment
As Fig. 1, shown in Figure 2, get two boards thick low carbon steel or aluminum alloy or copper alloy plate for 4mm or 1mm or 2mm or 3mm, it is identical to stamp out the aperture with crank or hydraulic press on a plate-upper plate 1, be evenly distributed and divide several plate holes 1A that arranges and put, be controlled at 265～290Mpa for the low carbon steel plate punching pressure, be controlled at 240～265Mpa for aluminium alloy plate and copper alloy plate punching pressure, ratio is 1: 1 or 1: 2 or 1: 1.5 between the diameter of said plate hole 1A and the thickness of slab, and two adjacent rounds are dislocatedly distributed, repair plate hole 1A again, remove plate week burr, chimb and concave edge, like this, after the riveted joint, intensity can be very high, and attractive in appearance.
As shown in Figure 3, Figure 4, the stamped bumps 2A on another piece plate-base plate 2 with crank or hydraulic press, projection 2A external diameter φ d cooperates with plate hole 1A on the upper plate 1, and number unanimity, between the projection 2A between distance and the plate hole 1A pitch-row consistent, the Deviation Control of the two distance that cooperatively interacts 0～± the 0.05mm scope within.Otherwise it is not attractive in appearance that riveting goes out postforming grade, and insecure.
As shown in Figure 5, protruding 2A on plate hole 1A on the upper plate 1 and the base plate 2 is aligned, adjust die sinking and die height (otherwise, can press not firm, 2 liang of plate riveted joints of upper plate 1 and lower plate pine rocks after the riveting, and, intensity reduces after the riveting), under crank or hydraulic press effect, be riveted together.For low carbon steel plate, the pressure control of said press machine is at 155～170Mpa; For aluminium alloy plate and copper alloy plate, the pressure control of said press machine is between 140～155Mpa, and (can not select too big pressure for use, like this, crackle can appear in plate.Simultaneously, can not select too little pressure for use, otherwise plate can be pressed unreal, intensity does not reach.)
