AI Technical Summary

Problems solved by technology

This production method cannot be produced on a large scale, and only a section of strip with a small length can be processed each time. This process cannot be used for continuous processing, and the production efficiency is extremely low.
With the wide application of electronic products, the demand for electrical contacts is also increasing, and the market prospect is very optimistic. However, the current domestic production process has extremely low production efficiency, poor strip bonding strength, poor composite fastness, and its production The cost is extremely high, far from meeting the current market demand

Embodiment Construction

[0026] For further prompting the present invention, below in conjunction with appendix figure 1 , 2 , 3, 4, 5, 6, 7 for specific instructions.

[0027] The copper strip 6 of the present invention is a copper or copper alloy strip, and there is a thinner silver strip 17 transition layer between the silver tin oxide strip 16 and the copper strip 6 on the produced silver / copper double-sided composite strip , its processing technology is as follows:

[0028] A, carry out surface cleaning to silver band 17 and silver tin oxide band 16 bands respectively, remove oil stain, oxide compound on its surface, then silver band 17 and silver tin oxide band 16 are sent into hot-rolling mill hot-rolled and compounded together again One piece of silver tin oxide / silver composite strip 15, the heating temperature of hot rolling composite is 300-800°C, the strip running speed is 1.0-5.0m / min, the rolling force is 10-120 tons, 10 in the heating zone has protection Then put the silver tin oxide...

Abstract

This invention relates to electricity materials technique field and to one silve to copper double compound band process method, which comprises the following steps: firstly grinding the silver metal oxidation with one thin siver band to form silver metal oxidation or silver compound materials; grinding silver metal oxidation and silver compound band through its top silver band layer and copper band heat grinding through heat compound band for annealing.

Description

Technical field: [0001] The invention relates to the technical field of electrical contact materials, in particular to a processing technology of a silver / copper double-sided composite strip. Background technique: [0002] Electric contacts are contact elements of electrical switches and instruments. It is mainly responsible for connecting and breaking currents. It plays a decisive role in the safe operation of electrical appliances. Among the materials for producing electrical contacts, silver metal oxides (such as silver Tin oxide AgSnO2, silver cadmium oxide (AgCdO) materials are widely used in low-voltage electrical appliances due to their good resistance to electrical wear, welding resistance and electrical conductivity. Silver tin oxide / copper double-sided composite material is a new type of functional material composed of silver metal oxide and copper through a special composite process. It not only retains the main characteristics of silver metal oxide and substrate ...
