Abstract

The invention discloses a pressure welding device, which comprises a power supply switch (1), a power supply module (2), a speed sensor (3), a first A / D (analog-to-digital) converter (4), a PLC (programmable logic controller) control circuit (5), a second A / D converter (6), a start push button (9), a stop push button (10), a servo driving circuit (14), a servo driving motor (15), a roller type welding head (16), a pressure welding machine (17) and a welding current controller (18). The pressure welding device has the advantages that the dot type welding head of the pressure welding machine is manufactured into the roller type welding head, so the structure is simplified, and the welding efficiency is improved; a photoelectric protection device is arranged, so the occurrence of production accidents is avoided, the welding speed can be adjusted, and the high-efficiency welding is realized; and meanwhile, the welding current can be controlled according to the practical conditions, such as specific welding materials and thicknesses, and then the optimum welding effect is realized.

Description

technical field [0001] The invention relates to a pressure welding device. Background technique [0002] Pressure welding is to make two workpieces realize interatomic bonding in a solid state under pressure, also known as solid-state welding. The commonly used pressure welding process is resistance butt welding. When the current passes through the connecting end of the two workpieces, the temperature rises due to the large resistance. When heated to a plastic state, it is connected into one under the action of axial pressure. Since pressure welding is characterized by applying pressure during welding without adding filler material. There is no melting process in pressure welding, so there is no burning of beneficial alloy elements like fusion welding, and the problem of intrusion of harmful elements into the weld, thus simplifying the welding process and improving welding safety and hygiene conditions. At the same time, because the heating temperature is lower than th...
