Embodiment Construction

[0045] like figure 1 and figure 2 As shown, it is a multi-layer foil welding machine 3. The welding machine 3 is provided with an unwinding roller 1 and a winding roller 4 before and after the welding machine 3. The multi-layer foil is rolled into a roll and placed on the unwinding roller 1. After one end is heated and pressed by a welding machine to form a composite foil, it is re-rolled on the winding roll 4 into a roll.

[0046] The welding machine 3 includes an upper punch 31, a connecting plate 32 fixedly connected to the lower end of the upper punch 31, an upper heating assembly 34 fixedly connected to the lower portion of the connecting plate 32, and a lower heating assembly 35 placed on the bottom plate 36, The upper and lower heating assemblies, the connecting plate 32 and part of the upper punch 31 are placed in the protective atmosphere box 33; the top of the protective atmosphere box 33 is provided with an opening, the upper punch 31 extends into the opening, and...

Abstract

The invention discloses a multi-layer foil welding machine, which comprises an upper punch moving vertically up and down, an upper heating assembly fixedly connected with the upper punch, and a lower heating assembly fixedly arranged directly below the upper heating assembly , the bottom plate supports the lower heating assembly at the lower part of the lower heating assembly, the protective atmosphere box is sleeved on the outside of the upper and lower heating assemblies, the upper part of the bottom plate, and the bottom plate seals the bottom thereof, The upper punch extends into the protective atmosphere box from its top. From the top, a protective gas with a pressure greater than atmospheric pressure is introduced into the protective atmosphere box to prevent air from entering the protective atmosphere box, so that oxidation reaction occurs when the multilayer foil is heated; When the heating components are combined, heat and pressurize the multi-layer foil between the two to make it welded into a composite foil.

Description

technical field [0001] The invention belongs to the technical field of mechanical heating equipment, in particular to a multi-layer foil welding machine and a welding method. Background technique [0002] The common preparation method of single-layer metal foil is flat roll belt rolling. Softer metals such as aluminum foil and tin foil are mostly rolled with four rolls or two rolls; for metals with high deformation resistance such as copper, nickel, titanium and tungsten, Foils such as molybdenum are rolled by rolling mills with high rigidity and small roll diameter, and foils with a single-layer thickness of 0.001 mm can be rolled. In addition to the rolling method, the industry also uses the electrolytic deposition method to manufacture copper foil for printed circuits and the vacuum evaporation method to manufacture aluminum foil for packaging. [0003] By fusing together foils of different materials, a composite foil with better comprehensive properties can be obtained....
