Description

Technical Field

[0001] The present application relates to the technical field of titanium wire forming processing, and in particular to a surface lubrication device before titanium wire forming processing. Background Art

[0002] Titanium wire is a wire product made of titanium metal through a special processing process. Titanium is widely used in various fields, such as aerospace, petrochemical, medical care, sports and leisure products, etc., due to its excellent properties, such as high strength, low density and good corrosion resistance. In the field of aerospace, titanium wire is widely used due to its light weight, high strength and high temperature resistance; in the field of medical care, titanium wire is used to manufacture medical devices and artificial joints due to its good biocompatibility and non-toxic properties; in the automotive field, titanium wire is used to manufacture automotive parts due to its high strength and corrosion resistance.

[0003] At present, the forming process of titanium wire is mainly through rolling, drawing and other processing methods, and the final forming diameter can be less than 1mm. The forming process of titanium wire is mainly carried out on the basis of titanium rods, by using wire drawing dies with various inner diameters, as shown in the attached manual. Figure 1 As shown, titanium rods with smaller diameters can be gradually reduced in diameter and drawn into titanium wires with diameters that meet the requirements. Since the use of a wire drawing die is a mechanical wire drawing operation (specifically, the outer diameter of the titanium rod to be drawn is slightly larger than the inner diameter of the wire drawing die, and after the thin titanium rod passes through the wire drawing die, the outer diameter of the titanium rod is driven to decrease by mechanical extrusion to achieve a single diameter reduction wire drawing operation), when the thin titanium rod continuously passes through the inner hole of the wire drawing die in the axial direction, there is a large sliding friction with the inner wall of the die. When there are defects in the internal structure of the thin titanium rod or the oxide scale adheres to the port of the wire drawing die and hinders the passage of the titanium rod, the titanium wire is easily broken under the large axial drive traction and the extrusion of the die (such as Figure 2 As shown in the figure), the drawing length of the titanium wire cannot be guaranteed. Therefore, in order to solve this problem, the following Figure 3-4 As shown, before wire drawing, a lubricant box is provided. After the titanium wire passes through the lubricant, the lubricant in the box (usually graphite or other powdered lubricant) adheres to the surface of the titanium wire, so that during the wire drawing process, it can smoothly pass through the wire drawing die to ensure the drawing length of the titanium wire.

[0004] At present, after the titanium wire passes through the lubricant box, the lubricant adheres to it. After passing through the lubricant box, the adhered lubricant will fall off under the axial movement of the titanium wire, thus causing the wire to accumulate on the wire drawing workbench ( Figure 5 As shown), it causes waste of lubricant and reduction and insufficiency of lubricant in the lubricant box, thus affecting the continuous wire drawing operation of titanium wire. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a surface lubrication device before titanium wire forming processing, which can clean the lubricant powder that adheres to the surface of the thin titanium rod and is easy to fall off before the titanium wire passes through the box body, thereby avoiding the problem of lubricant powder adhered to the titanium wire after passing through the box body falling on the workbench and causing waste.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a surface lubrication device before titanium wire forming processing, the lubrication device is a box body, and through holes for passing the titanium wire are opened on its symmetrical side walls, and a lubricant for immersing the titanium wire is contained in the box body, which is characterized in that: a cleaning mechanism is arranged on the through hole, which contacts the surface of the titanium wire and separates the adhered lubricant from the titanium wire, and a collecting mechanism is arranged on the outside of the box body, which collects the lubricant that adheres to the surface of the titanium wire and falls to the outside of the box body.

[0007] Preferably, the cleaning mechanism is a rotating ring rotatably arranged in the through hole, and a brush body is arranged on the inner circumference of the rotating ring to be in rotational contact with the circumference of the titanium wire.

[0008] Preferably, the collecting mechanism is a collecting box body arranged on a side of the box body through which the titanium wire passes, a collecting cavity is formed between the collecting box body and the outer wall of the box body, and the collecting box body is provided with the through hole.

[0009] Preferably, the perforations are arranged as a vertical strip structure in the vertical winding direction of the titanium wire spiral.

[0010] The beneficial effect of the present application is that the surface lubrication device is equipped with a cleaning mechanism on the box body, which can clean the lubricant powder that adheres to the surface of the thin titanium rod and is easy to fall off before the titanium wire passes through the box body, thereby avoiding the problem of lubricant powder adhering to the titanium wire after passing through the box body falling on the workbench and causing waste.

[0011] The collecting mechanism arranged outside the box body can collect a small amount of lubricant powder that falls to the outside of the box body, thereby solving the problem of dust hazards that are easily generated. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached Figures 1 to 9 The lubricating device shown is a surface lubricating device for titanium wire before forming. The lubricating device is a box body 1, and a through hole 1a for passing the titanium wire is opened on its symmetrical side wall, and a lubricant for immersing the titanium wire is contained in the box body 1. Figure 1 As shown, currently, the thin titanium rod to be drawn passes through the through hole 1a of the box body 1, so that the titanium rod can be immersed in the lubricant in the box body 1 to achieve lubrication. After passing through the box body 1, the lubricant powder adhered to the surface of the titanium rod is easy to fall and gather on the workbench under the shaking of the titanium wire, thus causing waste. Therefore, in order to solve this problem, as Figure 7-8 As shown, a cleaning mechanism is provided on the perforation 1a, which contacts the surface of the titanium wire and separates the adhered lubricant from the titanium wire. The cleaning mechanism can clean the lubricant powder that adheres to the surface of the thin titanium rod and is easy to fall off before the titanium wire passes through the box body 1, thereby avoiding the problem of lubricant powder adhered to the titanium wire after passing through the box body falling on the workbench and causing waste.

[0024] However, since a certain amount of lubricant powder still needs to adhere to the surface of the titanium rod, when the cleaning mechanism has not completely cleaned up the powder that is easy to fall, the powder will still fall to the outside of the box body 1. Therefore, in order to collect the small amount of fallen powder and avoid dust hazards in the production site, a collecting mechanism is provided on the outside of the box body 1 to collect the lubricant that adheres to the surface of the titanium wire and falls to the outside of the box body 1. The collecting mechanism can collect a small amount of lubricant powder that falls to the outside of the box body 1, thereby solving the dust hazards that are easy to generate.

[0025] Specifically, Figure 7-8 As shown, the cleaning mechanism is a rotating ring 2 rotatably arranged in the through hole 1a, and a brush body 3 is arranged on the inner circumference of the rotating ring 2 to be in rotational contact with the circumference of the titanium wire. When the titanium rod immersed in the lubricant is passed through the brush body 3, the lubricant that is easy to fall off the surface of the titanium rod is brushed off by the brush body 3 (the brushing distance between the end of the brush body 3 and the surface of the titanium rod is designed), and the lubricant powder after brushing falls into the box body 1, thereby avoiding the waste and dust hazards caused by the lubricant powder that is easy to fall falling to the outside of the box body 1. Since the brush body 3 is rotatably arranged in the rotating ring 2, the circumferential deflection existing during the axial movement of the titanium rod can also drive the brush body 3 to rotate circumferentially, thereby realizing the circumferential brushing effect.

[0026] In order to further collect a small amount of lubricant powder that falls outside the box body 1, as shown in FIG. Figure 6 As shown, the collecting mechanism is a collecting box body 4 arranged on one side of the titanium wire passing through the box body 1, a collecting cavity 4a is formed between the collecting box body 4 and the outer wall of the box body 1, and the collecting box body 4 is provided with the perforation 1a. The perforation is used for the titanium wire to pass through, and the fallen lubricant powder is accumulated in the collecting cavity 4a of the collecting box body 4 for collection, thereby solving the problem of a small amount of lubricant powder scattered outside the box body 1 causing waste and generating dust hazards.

[0027] During the process of the titanium wire adhering to the lubricant, it needs to be pulled so that it can continuously pass through the box body 1 and perform the lubricant adhering operation, such as Figure 3 As shown, a traction wheel is usually provided on one side of the box body 1, which pulls the unwinding titanium wire and passes through the box body 1, and then the titanium wire adhered with lubricant is wound on the traction wheel, and the winding method is usually spiral upward winding ( Figure 3 As shown by the arrow in the middle), as the titanium wire winding increases, the titanium wire will be restricted by the perforation 1a. Therefore, in order to solve this problem, Figure 7 As shown, the perforation 1a is set as a vertical strip structure in the vertical winding direction of the titanium wire. The perforation 1a of this structure can adapt to the spiral winding and rising of the titanium wire to avoid bending, breaking and other problems in the winding process. At the same time, the box body 1 is preferably at the same height as the traction wheel, and a sufficient amount of lubricant is contained therein. The swivel 2 is vertically slidably set in the perforation 1a of the strip structure and moves up and down with the titanium wire.

[0028] In order to prevent the lubricant powder in the box body 1 from flowing out of the perforation 1a on the side where the titanium wire enters the box body, preferably, a collecting box body 4 is also provided on this side to achieve a symmetrical arrangement on both sides of the box body 1, and similarly, perforations 1a with the same structure are opened on the collecting box bodies 4 on both sides.

[0029] The principle of the present application is: during operation, the end of the titanium wire is first passed through the collecting box body 4, the through hole 1a on one side of the box body 1 and the brush body 3 on the other side, and the through hole 1a of the collecting box body 4 on the other side and is wound and fastened on the traction wheel, and then the traction wheel is started to rotate automatically, the titanium wire on the unwinding disk is unwound, and the titanium wire continues to pass through the box body 1 and is immersed in the lubricant powder to achieve lubricant adhesion, and the titanium wire after adhesion passes through the brush body 3, and the lubricant powder that is easy to fall off its surface is brushed off into the box body 1 through the brush body 3, and the lubricant powder adhered to and fallen on the surface of the titanium wire after passing through the box body 1 falls into the collecting box body 4 and is collected.

[0030] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
