The copper-aluminum dissimilar metal pressure deposition welding machine is simple and convenient to operate, can not only prevent oxidation of interface but also realize connection of different metals in good quality and high efficiency.
Description
Technical field
The utility model belongs to dissimilar metal solder technology field.
Background technology
The dissimilar metal syndeton has two kinds of premium properties that material is comprehensive, obtained using widely in national defence and national product field, and application prospect constantly enlarges.
As, copper has fabulous electric conductivity, thermal conductivity, but because the price comparison of copper is expensive, brings huge cost pressure for the relevant enterprise in electrical engineering field.Aluminium and aluminium alloy have excellent physical characteristics and mechanical property equally.In order to save production cost, part electric product or parts become a trend of current electrical equipment, electric power industry development with aluminium or copper and aluminium welding fitting Alloy instead of Copper.
But because the fusing point of two kinds of materials differs nearly 400 ℃, intersolubility is very limited, and in the conventional fusion process, the mass fraction of Cu generally all about 30%, produces compound between the aluminum bronze brittle metal inevitably in the joint, has a strong impact on strength of joint.Therefore be difficult for adopting traditional fusion welding method to weld.
Summary of the invention
The purpose of the utility model provides a kind of molten welding machine that applies of dissimilar metal pressure of realizing the high-quality and efficient connection of copper aluminium.
The utility model comprises frame; On frame, connect workbench, be connected with the pressing mold of inner chamber on the said workbench, outside said pressing mold, heating control apparatus is set; The vertical pressure sensor that connects connects pressure head in the lower end of said pressure sensor on the frame above the said pressing mold.
Remove earlier the greasy dirt and the oxide-film of Cu alloy material and aluminum alloy material surface respectively; Then Cu alloy material is placed in the pressing mold that is provided with inner chamber; At the upper surface uniform spreading protective agent layer of Cu alloy material, again aluminum alloy materials is kept flat on the protective agent layer subsequently; Start heating control apparatus; Make interior Cu alloy material of die cavity and aluminum alloy materials be warming up to the protective agent layer and melt fully, aluminium alloy also begins to melt moment simultaneously, stops heating immediately; Simultaneously; Through the controlled pressure working sensor, make pressure head apply pressure to the Cu alloy material surface downwards, make Cu alloy material and aluminum alloy materials realize that atom is connected.
The utility model is simple to operation, not only can prevent interface oxidation, finally realizes the high-quality and efficient connection of different metal.The utlity model has following remarkable advantage:
1, mechanism's advantages of simple is easy to operate, is easy to weld dissimilar metal, particularly the Cu-Al dissimilar metal;
2, can realize the protection of joint in whole welding process, avoid its oxidation in welding process;
3, strength of welded joint height, good airproof performance, electric conductivity are superior to aluminium.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model connects workbench 2 on frame 1, is connected with the pressing mold 3 of inner chamber on the workbench 2, and the heating control apparatus of being made up of load coil 4 and switch board 5 is set outside pressing mold 3.
The vertical pressure sensor 6 that connects connects pressure head 7 in the lower end of pressure sensor 6 on the frame above the pressing mold 31, and pressure sensor 6 links to each other with an industrial computer 8.
