Description

TECHNICAL FIELD

[0001] The utility model relates to cold welding machine technical field, concretely is a kind of fine enameled wire cold connection device. BACKGROUND

[0002] Cold pressure welding is a method of connecting non-ferrous metals and alloys by applying pressure without electricity, heat, filler and flux during welding. Two important factors for achieving cold pressure welding: one is a certain pressure applied between workpieces, which is a necessary condition for local plastic deformation and atomic bonding of metals; the second is that the metal on the end face of the workpiece must have sufficient plastic cold pressure under the action of pressure, which is a sufficient condition for welding. If cold pressure welding is carried out in a closed mold cavity, no matter how much pressure is applied, it will not achieve cold pressure welding because the metal cannot have sufficient plastic cold pressure.

[0003] Hand tongs type cold welding machine originated from continuous exploration and innovation of precision welding technology. With the development of manufacturing industry, the requirements for welding precision, efficiency and environmental protection are continuously improved, and traditional welding methods cannot meet the needs in some fields. Therefore, cold welding machine technology emerges as the times require and gradually develops into an important welding method. As a kind of cold welding machine, hand tongs type cold welding machine is gradually widely used in various fields due to its small size, portability, easy operation and high welding quality.
