Abstract
The invention discloses a plate connecting method capable of using prepressing holes of a soft rivet column and riveting compounding. The plate connecting method comprises the following steps: a connecting point is generated on an upper plate and a lower plate by adopting the prepressing holes, mechanical deformation is generated between the upper plate and the lower plate to form embedment, and thus the upper plate is connected with the lower plate together; the connecting point formed by connecting the upper plate and the lower plate through the prepressing holes is reversely buckled up on the rivet column to ensure the rivet column to be arranged in a pit formed in the upper plate; the upper plate, the lower plate and the rivet column are arranged between an upper mold and a lower mold; the upper mold moves downwards through a riveting process and extrudes the upper plate, the lower plate and the rivet column with matching of the lower mold, so that the rivet column has plastic deformation, is embedded into the upper plate and presses the upper plate to be further embedded into the lower plate at the connecting point to ensure increase of the connecting strength; and the height of a salient formed on the lower plate lowers under the pressure action of the upper mode. The plate connecting method has the advantages of high connecting strength and low salient height.
Description
Technical field
The invention belongs to sheet material interconnection technique field, be specifically related to a kind ofly use the precompressed hole of soft riveting post and the sheet material method of attachment of riveting compound.
Background technology
In recent years, the sheet material connectivity problem of same material, foreign material, same thickness and different-thickness got the attention.Adopt the sheet material Joining Technology of rivet interlacement poor, rivet can produce damage to plate surface, has a strong impact on the result of use of sheet material, in addition, because rivet and sheet material are foreign material, easily produces electrochemical corrosion, tie point is produced and loosens.
In addition, also have a kind of technology connecting sheet material mechanically deform press-in connection technique, mechanically deform press-in connection technique adopts special punch-die to carry out punching press to attaching plate elements, utilizes metal plastic deformation ability, reaches connection object by embedded between plate.Not only economy, the energy-saving and environmental protection of mechanically deform press-in connection technique, are also applicable to the connection being applied to heterogeneous abnormal shape, material surface has the covering such as coating or paint very much.Mechanically deform press-in connection single-point static strength is 70% of spot welding, and two point connection can be equal with spot welding, and resistance to vibration is higher than spot welding, and service life is longer than spot welding.But also there is fatal shortcoming in mechanically deform press-in connection.Owing to being that utilize between plate embedded reaches connection object, therefore certainly exist a higher projection in the side of plate, and opposite side there is a corresponding pit.Traditional mechanically deform press-in connection technique, owing to there being projection, therefore can not using in the occasion requiring plane relative sliding, limits the popularity that it uses.In addition, because both sides have pit and projection respectively, had a strong impact on its aesthetic measure, made it can not be used in the occasion having better quality to require to appearance.
Summary of the invention
In order to overcome above-mentioned shortcoming, the object of the present invention is to provide and a kind ofly use the precompressed hole of soft riveting post and the sheet material method of attachment of riveting compound, significantly can reduce the height of tie point, and increase the intensity of tie point.
To achieve these goals, the technical solution used in the present invention is:
Use the precompressed hole of soft riveting post and a sheet material method of attachment for riveting compound, comprise the following steps:

Second step, the tie point formed after being connected by precompressed hole with lower plate 2 by upper plate 1 tips upside down on riveting post 5, in the pit that riveting post 5 is placed on upper plate 1, by upper plate 1, lower plate 2 and riveting post 5 are placed between mold 3 and bed die 4, by riveting technique, mold 3 moves downward, upper plate 1 is extruded under the cooperation of bed die 4, lower plate 2 and riveting post 5, make riveting post 5 that plastic deformation occur, be embedded in upper plate 1, and oppress upper plate 1 and be embedded in lower plate 2 further at tie point place, bonding strength is increased, projection in lower plate 2 is height reduction under the pressure effect of mold 3.
In riveting technique, the material of riveting post 5 outwardly, in the pit that the flowing of material can make riveting post 5 be embedded on upper plate 1, and makes upper plate 1 be embedded into further in lower plate 2 at tie point place around the pit on its upper surface and lower surface simultaneously.
The shape of described riveting post 5 is cylindric, and on cylinder, plane is provided with pit, and cylinder lower plane is provided with lower pit, and its parameter comprises riveting column diameter d
3, riveting post height h, upper pit diameter d
2, lower pit diameter d
1, upper pit depth l
2, lower pit depth l
1, upper pit cone angle
2, lower pit cone angle
1with riveting post fillet R, the combination different by above-mentioned parameter can produce different connection effects.
Described upper plate 1, the material of lower plate 2 are identical.
The material of described riveting post 5 is identical with the material of upper plate 1.
The material of described riveting post 5 is aluminium alloy or copper alloy.
The present invention has the following advantages:
(1) traditional rivet needs to do Quenching Treatment, and shape is be with the cup shell of sharp-pointed tooth, and cost is high.And the soft riveting post manufacturing process that the present invention uses is simple, cost is low.
(2) traditional toothed rivet has damage to the sheet material connected, and which increases antiseptic difficulty, causes sheet material easy corrosion in junction.And the riveting post that the present invention adopts utilizes plastic deformation to be linked together by sheet material, to sheet material not damaged completely.
(3) riveting column material of the present invention is the material that the plasticity such as aluminium alloy, copper alloy identical with sheet material is good, and material is softer, is applicable to plastic working, can mass production.
(4) riveting post be connected sheet material and adopt same material, can not electrochemical reaction be there is between riveting post and sheet material afterwards in riveted joint, therefore the riveting of riveting post good after do not exist loosening.
(5) effectively can reduce the height of tie point projection after adopting riveting post to carry out riveting, improve tie point outward appearance, make it apply more extensive.
(6) the method effectively can increase the intensity of tie point.
