Abstract
A process for binding Cu with AI includes heating AI component to be temperature of 410-430deg.c and holding the temperature, coating a layer of Su on binding surface of Cu plate, coating a layer of Su on terminal surface of heated AI component and burring it by steel brush as well as coating a layer of Su on burred terminal surface, laying iron plate in temperature of 600-700deg.c on operation table, setting AI component with Su layer on said iron plate and Cu plate with Su at surface on said AI component then pressing them tightly for 15 minutes.
Description
Technical field
The present invention relates to a kind of non-ferrous metal technique for sticking, relate in particular to the technology that copper and aluminium are bonded as one.
Background technology
Conducting rod on the electric equipments such as transformer mostly is copper, and the lead that connects mostly is aluminum steel, because copper aluminium connects need be tight especially, and certain connection area to be arranged, otherwise the phenomenon that current-carrying area deficiency or the galvano-cautery of copper aluminium will occur, therefore, between conducting rod and lead, a wire clamp that is made of two kinds of materials of copper aluminium to be arranged also.At present, it is little that the device clamp in the electric armour clamp product exists between the copper aluminum component bonded area, and the waste of copper material is many, and copper and aluminium welding connects apparatus expensive, and the welding cost height is with the defectives such as area is little and not tight that are connected of equipment conducting rod and lead.
Summary of the invention
The present invention is directed to above defective provides a kind of and copper sheet is closely pasted become an integral body on aluminum component, make the aluminum component part be covered with copper, improves the conductive performance that is connected of aluminum component and copper conductor, and a kind of copper aluminium welding technology at the bottom of the processing cost.
A kind of copper aluminium welding technology of the present invention, it may further comprise the steps:
1), aluminum component is heated to 410～430 ℃, insulation;
2), on the bonding plane of copper sheet, apply one deck tin;
3), the aluminum component taking-up with above-mentioned heating is coated with one deck tin at terminal surface, use the steel brush hacking, on the terminal surface behind the hacking, be coated with one deck tin more uniformly, get the red iron plate temperature of burning in the stove about 600～700 ℃, be placed on the workbench of frock, the aluminum component that is coated with full tin layer is placed on this iron plate, and the surface has the copper sheet of tin to place on the aluminum component again, puts cushion block operation frock and compresses.
4), impaction state kept taking-up 15 minutes.
Described frock is a spinning machine.
The tin coating layer is on the copper sheet: copper sheet is carried out pickling, immerse in the tin liquor of fusing after the pickling, taking-up is dried.
The present invention has made full use of good heat conductivity and the low-melting characteristic of tin of copper aluminium, and copper sheet is bonded on the aluminium matter wire clip body securely by tin; Adopted simple spinning machine, shelved a temperature and reach 900～1000 ℃ iron plate on the workbench of spinning machine, aluminium material surface has slight thawing in spinning process, and tin is in melting state, and copper, tin, aluminium are bonded as one.Copper aluminium welding face of the present invention is big, connects closely, need not use solderer promptly to finish incorporate bonding processing, low processing cost because the part of aluminum component is covered with copper sheet, aluminum component and copper conductor to be connected conductive performance good.
Embodiment
The present invention at first is heated to aluminum component 410～430 ℃, heat preservation for standby use, and the preferred heating-up temperature of present embodiment is 420 ℃, the temperature error of permission is positive and negative to be no more than 10 ℃.
On the bonding plane of copper sheet, apply one deck tin then; The method of tin coating layer is on the copper sheet: copper sheet is carried out pickling, remove surface dirt impurity, immerse in the tin liquor of fusing after the pickling, taking-up is dried.
On the workbench of spinning machine, put a temperature and be 600～700 ℃ iron plate, this iron plate is that the temperature and the tin work in-process of work piece can melt when keeping compressing, above-mentioned aluminum component places on this iron plate, and the surface has the copper sheet of tin to place on the aluminum component again, and the operation spinning machine compresses.
Impaction state kept 15 minutes, took out, and made.
Claims (3)
1, a kind of copper aluminium welding technology is characterized in that, it may further comprise the steps:
1), aluminum component is heated to 410～430 ℃, insulation;
2), on the bonding plane of copper sheet, apply one deck tin;
3), to put a temperature on the workbench of frock be 600～700 ℃ iron plate, above-mentioned aluminum component places on this iron plate, the surface has the copper sheet of tin to place on the aluminum component again, the operation frock compresses;
4), impaction state kept taking-up 15 minutes.
2, a kind of copper aluminium welding technology according to claim 1 is characterized in that, described frock is a spinning machine.
3, a kind of copper aluminium welding technology according to claim 1 is characterized in that, the tin coating layer is on the copper sheet: copper sheet is carried out pickling, immerse in the tin liquor of fusing after the pickling, taking-up is dried.
