An anti-oxidation device for copper wire drawing and annealing

Abstract

The present invention relates to the technical field of copper wire drawing, in particular to an anti-oxidation device for annealing copper wire drawing, including a clamping device for clamping copper wire, a wiper arranged between the clamping devices for wiping copper wire and A dripping device, the clamping device is provided with a dripping port, and the dripping device drips the anti-oxidation liquid onto the wiper through the opening. In the present invention, the anti-oxidation liquid is directly dripped on the wiper, avoiding direct contact between the high-temperature copper wire and the anti-oxidation liquid, and avoiding danger; the wiper soaked in the anti-oxidation liquid can clean the high-temperature copper wire and remove the metal on the surface of the copper wire Chips, improve the coating effect of the insulating layer, make the thickness uniform, and can cool the high-temperature copper wire and prevent oxidation; the dripping device can control the flow of anti-oxidizing liquid to maintain stable consumption, and at the same time set the dripping port The protective cover can condense and recycle the high-temperature vaporized anti-oxidation liquid to reduce the waste of anti-oxidation liquid.

Description

Technical field [0001] The invention relates to the technical field of copper wire drawing, in particular to an anti-oxidation device for copper wire drawing annealing. Background technique [0002] Wire is an indispensable material for users in the process of using electricity. It is widely used in various electronic systems, information transmission systems, mechanical equipment, instrumentation systems, etc. in people's daily life and industrial production. Wires include enameled wires, wires, cables, etc., and their conductive components are generally metallic copper. The present invention is mainly used in the automatic production line of continuous drawing, continuous withdrawal and continuous extrusion of single cable insulation. In the production process, copper wire is generally required to be drawn first and drawn to the required diameter through a mold. In the drawing process, after the copper wire undergoes cold working and plastic deformation, the internal crystal g...

Problems solved by technology

However, in the current production process, the temperature of the copper wire is very high after annealing, and the copper wire will be oxidized immediately when it encounters air.

Therefore, water sealing is generally carried out in the annealing chamber. At the same time, an appropriate amount of antioxidant is injected into the water. The disadvantage is that the cost of the antioxidant is high, and the filled antioxidant is very easy to corrode the metal door frame of the annealing device.

The anti-oxidation device for copper wire drawing and annealing described in application number 201320535073.1, the hydraulic pump pumps out the alcohol in the box and transports it to the nozzle through the hose, the alcohol sprayed from the nozzle encounters the high-temperature copper wire just after annealing, and instantly It is alcohol vapor, which makes the temperature of the copper wire drop significantly, and forms an alcohol evaporation layer on its surface in the catheter to isolate the copper wire from the air, thereby preventing the copper wire from oxidation. The disadvantage is that the structure of the device is complicated, and the alcohol consumption is large. Direct contact with high-temperature copper wire can easily cause fire and other hazards
