Description

Titanium alloy full-circle line lubrication film device

This creation is about a device for lubricating a film of a titanium alloy with a full circle.

The traditional Gr.5 titanium alloy coating treatment before the line is divided into two categories, the first type is the off-line batch type immersion/spray type, and the second type is the addition of coating and drying equipment in front of the line drawing machine. The two types of practices described above have the following disadvantages:

(1) The coating of the first type of equipment is relatively uneven;

(2) The first type of equipment requires additional handling equipment, and the handling process may cause damage to the coating;

(3) The first type of equipment requires additional drying equipment;

(4) The second type of equipment needs to be equipped with linear coating and drying equipment in front of the equipment. It takes about 5 meters and the drying temperature is set to about 200 °C. The resistance electric heater is heated by air conduction, which is quite energy-consuming and occupied. space.

In order to solve the above problems, the present invention proposes a titanium alloy full-circle line lubrication film device, comprising: a straightening wheel set for straightening a titanium alloy wire into a straight state; a graphite slurry coating device, disposed in a downstream of the straightening wheel set for pouring graphite slurry on the titanium alloy wire; an inductive heating furnace disposed downstream of the graphite slurry coating device for drying the graphite on the titanium alloy wire a slurry; and a drawing eye mold disposed downstream of the inductive heating furnace for performing a wire drawing reduction process on the titanium alloy wire.

This creation department moves the original off-line coating and drying process to the hot pump for on-line coating. Because the uniformity of the coating on the line after the unwinding of the wire is better than that of the whole line, it can be heated when the wire is heated. At the same time, the spray coating is dried, and the coating peeling caused by the disk transportation can be reduced, thereby greatly improving the coating uniformity, reducing the drying process and the two processes, thereby reducing the energy consumption and consumption of the production. Time.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following detailed description will be made in conjunction with the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described above.

Referring to FIG. 1 , the titanium alloy full-circle line lubrication film device comprises a straightening wheel set 110, a graphite slurry coating device 120, a ring-shaped high-pressure gas nozzle 130, a ring-shaped tube 140, and an inductive heating furnace. 150, graphite powder box 160 and drawing eye mold 170.

After the unwinding of the Gr. 5 titanium alloy wire 190, the horizontal and vertical straightening wheel sets 110 are straightened to a straight state so as to pass through the graphite slurry coating apparatus 120. The graphite slurry coating device 120 is disposed downstream of the straightening wheel set 110. The graphite slurry coating device 120 controls the flow rate by a nozzle. The Gr. 5 titanium alloy wire 190 passes under the nozzle, and the graphite emulsion is poured by gravity. On the titanium alloy wire 190.

The ring type high pressure gas nozzle 130 is disposed downstream of the graphite slurry coating apparatus 120, and functions to eject a high pressure gas to remove excess graphite slurry on the titanium alloy wire 190, and uniformly apply the graphite emulsion to the titanium alloy wire 190. The surface, especially the coating of the lower surface.

The annular duct 140 is disposed downstream of the annular high-pressure gas nozzle 130, and functions to further uniformly coat the graphite slurry on the titanium alloy wire 190 and wipe off excess moisture to form a graphite lubricating film. The thickness of the graphite lubricating film is controlled between 0.02 and 0.10 mm, and the water content is low, so as to prevent a large amount of residual moisture from being carried into the rear inductive heating furnace 150.

The inductive heating furnace 150 is disposed downstream of the annular duct 140 and has a length of 1.2 m. The function is to heat the titanium alloy wire 190 to 500-600 ° C to increase the workability of the titanium alloy and to bake the graphite lubricating film. dry. If a large amount of moisture is introduced into the heating furnace 150, the water vapor is evaporated by the high temperature and condensed into water droplets at a lower temperature in the ceramic tube of the heating furnace 150. When the water droplets continue to accumulate, it will overflow to the high voltage induction coil, causing a serious short circuit discharge failure. Therefore, the inductive heating furnace 150 is equipped with a convection fan to discharge the evaporated water gas to avoid serious short circuit failure caused by condensation of water and gas on the electrical components.

The graphite compact 160 is disposed downstream of the inductive heating furnace 150. When the titanium alloy wire 190 having a graphite lubricating film on its surface passes through the graphite compact 160, a uniform lubricating powder adheres.

The wire drawing eye mold 170 is disposed downstream of the graphite powder box 160 for performing a wire drawing reduction process on the titanium alloy wire 190.

This creation department moves the original off-line coating and drying process to the hot pump for on-line coating. Because the uniformity of the coating on the line after the unwinding of the wire is better than that of the whole line, it can be heated when the wire is heated. At the same time, the spray coating is dried, and the coating peeling caused by the disk transportation can be reduced, thereby greatly improving the coating uniformity, reducing the drying process and the two processes, thereby reducing the energy consumption and consumption of the production. Time.

The titanium alloy round-line lubrication film device of the present invention has the following advantages:

(1) The coating equipment and the drying equipment are arranged on the wire drawing machine without additional space;

(2) Install a ring-type high-pressure gas nozzle and a ring-shaped cloth tube to make the coating film on the line uniform and the water content is low;

(3) A convection fan is installed in the inductive heating furnace tube to discharge the evaporated water gas out of the furnace tube to prevent condensation of water and gas in the electrical components, resulting in serious short circuit failure.

(4) Inductive heating furnace tubes dry the film at the same time in the heating wire process, which has the advantage of energy saving.

(5) Film coating, film drying, and wire heating process can be applied at the same time to increase production efficiency.

Although the present invention has been disclosed in the foregoing examples, it is not intended to limit the present invention, and any one of ordinary skill in the art to which the present invention pertains can be modified and modified without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
