Problems solved by technology

However, due to the small tension of this equipment and the inability of the abrasive cloth wheel to work continuously, it cannot be directly used for descaling and polishing of titanium and titanium alloy wires.
In particular, this equipment does not have a water spray cooling and dust removal device. If it is used for descaling and polishing of titanium and titanium alloy wires, the titanium powder produced during the work is extremely flammable in the air, and it is difficult to ensure safe production.

Embodiment Construction

[0032] An embodiment of the present invention will be described with reference to accompanying drawings 1, 2, 3, 4, and 5.

[0033] 1. Method for removing oxide layer of titanium and titanium alloy wire:

[0034] ①Straightening: first heat the titanium and titanium alloy wire to 500℃-800℃, and then straighten the titanium and titanium alloy wire with a straightening machine;

[0035] ② Phosphorus removal: first use a set of thick steel wire wheels to remove the oxide layer on the surface of titanium and titanium alloy wires, and then use a set of thin steel wire wheels to remove the remaining oxide layer on the surface of the titanium and titanium alloy wires;

[0036] ③ Polishing: first use three sets of abrasive belt wheels to rough polish the surface of titanium and titanium alloy wire, and then use a set of polishing wheels to finish polishing the surface of titanium and titanium alloy wire, and the three sets of abrasive belt wheels are used alternately. After one set of abra...

Abstract

The invention relates to a method for removing an oxidation layer on titanium and titanium alloy wires and a device thereof. The method includes the following steps: 1. straightening: a straightening machine is used for straightening the titanium and titanium alloy wires; 2. phosphorus removal: a steel wheel phosphorus removal machine is used for removing the oxidation layer on the surface of the titanium and titanium alloy wires; 3. polishing: a sand belt wheel polisher is used for polishing the surface of the titanium and titanium alloy wires. The device is sequentially provided from left to right with a pay-off stand (1), a clamping device (2), a heating device (8), a straightening device (3), two steel wheel phosphorus removal machines (13), sand belt wheel polishers (14), a guide and guard (6) and a vertical down drawing machine (7). On the basis of the present steel wheel phosphorus removal machine, the method is additionally provided with a heating device, a phosphorus removing and polishing machine, a cooling device, a dust removing device and a tension device, thereby forming a production line for removing the oxidation layer on a large and heavy titanium alloy wire, so as to reach the purpose of removing the oxidation layer and polishing.

Description

Technical field [0001] The invention relates to a method and equipment for removing oxide layers of titanium and titanium alloy wires. Background technique [0002] During the thermal processing of titanium and titanium alloy wires, an oxide layer is formed on the surface, and the thickness is generally 0.02 to 0.2 mm. The finished wire material requires removal of this oxide layer. The method of removing the oxide layer can be acid-base washing or mechanical processing. The acid-base washing method will cause relatively large pollution, and it is generally not used. It is difficult to uniformly remove the oxide layer even if the entire roll is pickled. The method of machining can be attributed to turning and grinding. For thicker bars, use lathes and centerless grinders. Thinner wires can be ground with emery cloth belts and abrasive belt wheels. Due to the high hardness of the titanium oxide layer, the abrasive belt wheels and abrasive belts are consumed during the grinding pro...
