Problems solved by technology

This equipment is a hot compound rolling mill, which can heat the copper strip separately, and then let the silver metal oxide strip and the copper strip be automatically bonded before rolling, and then press and roll, which solves the problem that the copper strip needs to be manually processed after heating in the past. The problem of the silver metal oxide tape being attached to the copper tape avoids safety accidents and greatly increases work efficiency

Abstract

The invention discloses manufacturing equipment and method of a compound silver belt, and relates to manufacturing equipment and methods of electric contact materials. The method comprises the following work flows: carrying out pre-treatment on a silver oxidization belt and a copper belt; heating the copper belt; compounding the silver oxidization belt and the copper belt so as to obtain a compound belt; annealing the compound belt; carrying out finish rolling on the compound belt; relieving stress on the compound belt; carrying out antioxidation on the compound belt; stripping the compound belt; and verifying the compound belt. The manufacturing equipment is a hot compound mill which can automatically attach the high-temperature copper belt and the silver oxidization belt. Compared with the prior art, according to the method, in the processing process, the silver metal oxidization belt is not heated while the copper belt is heated, and thus, silver metal oxide is prevented from being reduced due to reduction reaction of a protective atmosphere and the silver metal oxidization belt in the heating process. Meanwhile, the silver metal oxidization belt is placed in a slot of the copper belt, and then is rolled, so that the combining strength is relatively high and the compounding fastness is relatively good.

Description

Technical field [0001] The invention relates to the technical field of electrical contact materials, in particular to a manufacturing method and manufacturing equipment of a silver-copper composite strip. Background technique [0002] Electrical contact is the contact element of electrical switches and instruments. It mainly undertakes the function of making and breaking current. It has a decisive effect on the safe operation of electrical appliances. In the materials for the production of electrical contacts, silver metal oxides (such as silver Tin Oxide AgSnO 2 , Silver, cadmium oxide (AgCdO) material is widely used in low-voltage electrical appliances because of its good electrical wear resistance, welding resistance and conductivity. Silver tin oxide / copper 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 base copper, but...
