Abstract
The welding-riveting method may be used to connect two steel plates with organic coatings. A welding rivet that has a back cylinder and a front boss is inserted in each of two holes on the top steel plate. The said boss has a height equal to the thickness of steel plate, a diameter smaller than that of cylinder, and a conic body in the center of end face. Welding electrode discharges while pressing onto rivet to make the conic body penetrate the organic coating of the bottom steel plate, so connecting them together.
Description
Belong to the linking method between steel plate with organic coating.
Steel plate with organic coating surface coated one deck organic coating, because the insulating properties of organic coating, make the welding between steel plate with organic coating become difficult, needing to remove the coating of desiring weld welds again, as the described a kind of dot welding method of GB2096039A (Fig. 1), give and remove welding electrode (1) and steel plate with organic coating (2) earlier, (3) coating of institute contacting point, at contacted steel plate with organic coating (2,3) another place have by pair of conductive clamp (6) and the conduction connecting band (7) form the galvanic circle, when the welding electrode energising, after the pressurization, electric current forms a loop, with steel plate with organic coating (2,3) spot-welded together, first that welds 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 solder joint, this method complex procedures, the steel plate with organic coating that is connected is if two-sided coated, welding electrode and last, the coating of following steel plate with organic coating contacting point need be removed, and the coating damage of steel plate with organic coating venner 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 two-sided coated or single face coated, the connecting means of the steel plate with organic coating that the venner coating damage is also not serious.
The present invention is achieved in that as shown in Figure 2, in two joint borings of last steel plate with organic coating (2), respectively puts into a weldering rivet (5) that is " protruding " shape in hole (4).The schematic representation of weldering rivet is seen Fig. 3, and weldering rivet bottom is a cylindrical body, the diameter phi of boss
2Less than cylindrical diameter phi
1, the height h of boss
2Equal the thickness of coated steel sheet (2), there is a cone at the center of raised head face, 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 charging of capacitor energy storage type welding machine, 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 welding 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, 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 solder joint place venner is not obvious.
