Embodiment 1

[0024] refer to figure 1 , AgCuNi 20-2 The silver-copper-nickel alloy of the brand is melted into a square ingot in a vacuum intermediate frequency furnace, and then rolled into a square plate 11 with a thickness of 4.6mm and a side length of 450mm, and then annealed in a box-type resistance furnace at an annealing temperature of 650°C and a holding time of 50min .

[0025] The 400-ton two-way hydraulic press exerts pressure on the plate, the periphery of the plate is fixed, and the center moves downward to form a C-shaped concave structure 12 in section.

[0026] Continue to apply pressure to roll the C-shaped concave structure 12 into a long tube 13 with a U-shaped cross-section. The low end of the long tube 13 is closed and the upper end is open.

[0027] In the above process, the pressing speed is controlled to be 10cm / min; the inner diameter of the rolled pipe is 197mm and the outer diameter is 203mm, and the blanking at the bottom of the long pipe 13 is removed to form...

Abstract

The invention provides a method for manufacturing a large-diameter thin-walled silver-copper alloy collector ring and the large-diameter thin-walled silver-copper alloy collector ring manufactured by the method. The silver-copper alloy material is smelted into a square ingot, and then made into a plate, annealed, and then Apply pressure to the surface of the sheet and extend it into a long tube. The method of the invention has high yield, high production efficiency, low energy consumption, less loss, is not limited by weather conditions, can be used for large-scale production, and can also be used for the production of a small amount of products.

Description

technical field [0001] The invention relates to a conductive slip ring and a manufacturing method thereof, in particular to a slip ring formed by drawing and forming a rolled plate, and a manufacturing method thereof. Background technique [0002] Slip rings belong to the application category of electrical contact sliding connections, also known as conductive slip rings, collector rings, etc., are precision power transmission devices that realize the image, data signal and power transmission of two relative rotating mechanisms, and are especially suitable for unlimited continuous rotation , At the same time, it is necessary to transmit power or data from a fixed position to a rotating position, and has been widely used in factory automation, security, electric power, instrumentation, military and other electromechanical equipment. [0003] The large-diameter thin-walled silver-copper alloy (Ag-Cu alloy) slip ring is one of the key components of the missile launch system, and...
