Description

technical field [0001] The invention relates to the technical field of titanium alloy or pure titanium processing titanium wire, in particular to a preparation device and method for titanium wire. Background technique [0002] In the production process of titanium alloy or pure titanium to prepare titanium wire, the wire drawing process of changing the diameter from coarse to fine, the peeling process of removing surface oxide scale and impurities, and the wire winding process of arranging scattered products into regular products are all necessary. process. [0003] The above three processes are the key control process of production in the industry, which determine the production efficiency and yield of the whole product. At present, the hot drawing machine is generally used in the industry to carry out the drawing process, the peeling machine realizes the peeling process, and the wire winding machine realizes the wire winding process . These three processes operate indepe...

AI Technical Summary

Problems solved by technology

[0004] The above general process has the following disadvantages: 1. Graphite milk is used as a lubricant in the production process of the hot wire drawing machine, and the graphite powder is converted into dust after heating, which not only seriously pollutes the environment but also damages the health of the operator; 2. The operation of the hot wire drawing machine requires 900 Heating at a high temperature of about ℃, high energy consumption and high cost; 3. The titanium wire produced by the hot wire drawing machine has a high temperature, and employees are prone to burns; 4. The titanium wire produced by the hot wire drawing machine is easy to scratch or crack on the surface, which is easy to cause Product quality problems, if the employee breaks the titanium wire during operation, it is easy to injure the employee; 5. The hot drawing production process is complicated, such as producing 4.5mm titanium wire into 3.3mm titanium wire, and the specifications produced on the hot drawing machine are sequential It is 4.3mm-4.1mm-3.9mm-3.7mm-3.5mm-3.3mm. It is necessary to replace the mold 6 times on the hot wire drawing machine and repeat the wire drawing 6 times to meet the requirements; 6. The efficiency of hot wire drawing is low. Due to the unique properties of titanium alloys, The speed of the hot drawing production process is generally controlled at 3cm / s, which is relatively low; 7. The peeling process uses a peeling mold. Due to the low ignition point of titanium alloy and pure titanium, combustion often occurs during the peeling process, which is easy to cause fire; 8. When peeling Due to the instability of the size of the hot drawing, the skinning is often not clean once, and the skinning has to be done twice or even multiple times, resulting in high product loss and low efficiency; 9. In this process, the production concentration of the three processes from raw materials to products Low, no continuity and frequent product quality problems
