Abstract
The present invention relates to a welding and riveting method for connecting steel plates with an organic coating. Holes are drilled in two points on an upper steel plate with an organic coating, and a convex welding rivet is embedded in each hole; the lower part of the welding rivet is provided with a cylinder, and the diameter of a lug boss is smaller than that of the cylinder; the height of the lug boss is equal to the thickness of the upper steel plate with an organic coating, and the center of the end surface of the lug boss has a cone; the diameter of the base circle of the cone is smaller than that of the lug boss, and the cone angle of the cone is 60 to 100 DEG C; the diameter of the drilled hole in the upper steel plate with an organic coating is equal to that of the lug boss of the welding rivet. Welding electrodes send out electricity and boost voltage, and the conical point of the cone of the welding rivet penetrates through the coating on the surface of a lower steel plate with an organic coating; the conical point of the cone of the welding rivet is welded on the lower steel plate with an organic coating so as to realize the connection between two steel plates with an organic coating.
Description
Belong to the connecting means that steel plate with organic coating is asked.
The steel plate with organic coating surface applied one deck organic coating, because the insulating properties of organic coating, make the welding between steel plate with organic coating become difficult, for the connectivity problem GB2096039A that solves two steel plate with organic coating discloses " dot welding method of coated steel sheet " (Fig. 1), remove welding electrode (1) and steel plate with organic coating (2) in advance, (3) coating of institute contacting point, at contacted organic coating (2,3) galvanic circle that another place has pair of conductive clamp (6) and conduction connecting band (7) to form, when the welding electrode energising, after the pressurization, electric current forms a loop, with steel plate with organic coating (2,3) weld together, weld at first and can form the loop with welding electrode, after the energising, its heat can destroy the coating of second solder joint, make current lead-through, weld second point, this method complex procedures, welding electrode and last, the coating of following steel plate with organic coating contacting point need be removed, and the damage of the venner of steel plate with organic coating is serious.
The objective of the invention is provides a kind of coating that need not to remove the solder joint place for overcoming above-mentioned shortcoming, simple to operate, and steel plate with organic coating can be double-coated or single face coating, the connecting means of the steel plate with organic coating that the damage of venner is also not serious.
The present invention is achieved in that as shown in Figure 2, in two pending connection position borings of last coated steel sheet (2), respectively put into the weldering rivet (5) that is " protruding " shape in the hole (4), " plush copper is downward ", the schematic representation of weldering rivet is seen Fig. 3, weldering rivet bottom is a cylindrical body body, the diameter phi of boss
2Less than cylindrical diameter phi
1, the height h of boss
2Equal the thickness of steel plate with organic coating (2), there is a cone at the raised head face center, and the end circular diameter of cone is less than the diameter phi of boss
2, the cone angle alpha of cone is 60 °～100 °, the diameter of being holed on last steel plate with organic coating (2) equals the diameter phi of boss
2During connection, the condenser discharge welder charging, pressurizeed 0.6～0.8 second, because design has the taper tip on weldering rivet (5) raised head face, therefore under the acting in conjunction of welding electrode 1 pressurization and electric current, the taper tip punctures the lip-deep coating of steel plate with organic coating (3) down, make and form a galvanic circle between two electrodes, to weld rivet (5) and weld together, thereby realize the connection of steel plate with organic coating (2,3), and can carry out multiple spot as required and connect with following steel plate with organic coating (3).Boss number on the weldering rivet lower cylindrical body end face also can be made two or more.
Adopt the present invention that two steel plate with organic coating are connected, the thickness of last steel plate with organic coating is unrestricted, need not remove the coating at tie point place, and is simple to operate, do not need to establish the galvanic circle in addition, and the coating damage of venner is not obvious outside the solder joint place.
