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
The present invention relates to electric contact material technical field, especially a kind of silver, the manufacture method of copper composite strip and manufacturing equipment.
Background technology
Electric contact is the contact element of electric switch, instrument and meter, and it is mainly born and connects and the effect of breaking current, and it has decisive role to the safe operation of electrical equipment, and in the material of production electric contact, siluer metal oxide is (as siller tin oxide AgSnO
2, Agcdo AgCdO) material is owing to having good resistance to electrical wear, resistance fusion welding and electric conductivity are used widely in low-voltage electrical apparatus.Silver tin/copper oxide composite is the new function material being combined by special combination process by siluer metal oxide and copper bi-material, it had both retained the main characteristics of siluer metal oxide and base material copper, can obtain the not available performance of stock blend by complex effect again, both silver, the resistance to electrical wear of performance silver contact had been saved, the advantage such as resistance fusion welding and electric conductivity, can improve again mechanical performance, be an important joint silver technology.But the bond strength of siluer metal oxide and copper is poor, at present domestic is that the bar of yellow gold and oxygen-free copper is compound, face is compound in the research emphasis aspect silver-bearing copper composite, and these are not substantially the compound of silver-colored oxide and copper.Mode of production when now indivedual enterprises produce the composite of siluer metal oxide and copper is first with argon arc welding, the edge of siluer metal oxide plate ingot and thick copper ingot two materials to be welded, then under the protection of reducibility gas, with hot-rolling mill, carry out hot rolling repeatedly compound, in course of hot rolling, siluer metal oxide meeting and reducibility gas reaction, restore silver metal, in the silver-bearing copper composite of producing like this, the oxide content of silver is not high, simultaneously this mode of production can not large-scale production, can only process the band that a segment length is very little at every turn, utilize this kind of technique not process continuously, produce: efficiency is extremely low.
Summary of the invention
The present invention is directed to deficiency of the prior art; a kind of manufacturing equipment and manufacture method of composite silver band are provided; this method is mainly the complex method of a kind of siluer metal oxide band and copper strips; in process, siluer metal oxide band does not need to heat with copper strips simultaneously; so just avoid protective atmosphere and siluer metal oxide band generation reduction reaction in heating process, caused siluer metal oxide to be reduced.Simultaneously siluer metal oxide band is put into the groove that is opened in copper strips and is then carried out pressure rolling, and in conjunction with higher by force, compound fastness is better.Use this method to manufacture composite silver band, manufacturing equipment requires low, handling ease, and band length is long, is convenient to automation processing, can manufacture in enormous quantities, thereby greatly reduce costs.This equipment is a kind of hot composite rolling mill, can heat separately copper strips, then before pressure rolling, allow siluer metal oxide band and copper strips automatic attaching, again and then carry out pressure rolling, after having solved copper strips heating in the past, need manually to carry out the problem siluer metal oxide band laminating copper strips, avoid security incident, greatly increased operating efficiency.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of hot composite rolling mill by siluer metal oxide-copper composite band, comprise frame, conveying device, heater and pressure roller milling train, in described frame, be disposed with described heater and described pressure roller milling train, described conveying device comprises first conveying device and second conveying device, described first conveying device transportation copper strips, described second conveying device transportation siluer metal oxide band, described first conveying device is through described heater and described pressure roller milling train, between described heater and described pressure roller milling train, be provided with the material-pouring device matching with described first conveying device, described second conveying device is arranged on described heater top, match with described material-pouring device in described second conveying device one end.Arrange like this, on copper strips, first offer and be equipped with the groove mating with siluer metal oxide band.In this hot composite rolling mill, have first conveying device and second conveying device, first conveying device is carried copper strips, and second conveying device is carried siluer metal oxide band.Copper strips in first conveying device after heater before pressure roller milling train by material-pouring device with allow the siluer metal oxide band in second conveying device automatically enter in the groove on copper strips, and then compound by pressure rolling in pressure roller milling train.So just do not need manually siluer metal oxide band to be put on the copper strips that temperature is very high, avoided security incident, also increased operating efficiency.
