Description

Technical Field

[0001] The present application relates to the technical field of cleaning wire drawing dies used for titanium wires, and in particular to an inner wall cleaning device for titanium wire drawing dies. Background Art

[0002] Titanium wire is a filamentary material drawn from titanium metal through a special processing process. Compared with other metals, titanium has excellent mechanical and biological properties, so it is widely used in aerospace, petrochemical, healthcare and other fields.

[0003] At present, titanium wire drawing is done using a wire drawing die (see the attached manual). Figure 1 The wire drawing process is to drive the titanium wire with a diameter larger than the straight section in the wire drawing die through traction, so that the titanium wire passes through the wire drawing die. Under the mechanical extrusion of the straight section of the wire drawing die, the outer diameter of the titanium wire is reduced, thereby achieving the effect of reducing the diameter of the wire drawing. By selecting wire drawing dies with different inner diameters, the titanium wire can be formed into a finished titanium wire with a smaller outer diameter. During the wire drawing process, since the diameter of the titanium wire is larger than the inner diameter of the wire drawing die, an arc-shaped open section is provided to facilitate the titanium wire to penetrate into the wire drawing die. The inner diameter at the outer port is larger than the outer diameter of the titanium wire, and gradually decreases to connect with the straight section, so as to facilitate the smooth penetration of the titanium wire.

[0004] At present, during the wire drawing operation, the drawn titanium wire is usually long, so it is necessary to realize continuous wire drawing operation through the wire drawing die. During the continuous passing of the titanium wire through the wire drawing die, the oxide scale and debris on the surface of the titanium wire will be blocked and squeezed by the straight section of the wire drawing die and will fall off, and then usually adhere to the arc-shaped open section (such as Figure 6 As shown in the figure, the adhered oxide scale and debris will block the titanium wire from entering the wire drawing die, and will also scratch the surface of the titanium wire. Therefore, when the oxide scale and debris accumulate more, they need to be cleaned in time.

[0005] The current cleaning methods include manually using tools to remove the debris and using grinding equipment for grinding and cleaning. In these two methods, the wire drawing die, scraping tools or grinding equipment cannot be effectively fixed, and the open section of the wire drawing die is not a planar structure, and the direction needs to be constantly adjusted during cleaning. Therefore, it is currently very difficult to clean the wire drawing die. At the same time, under the action of external cleaning force, it is also very easy to cause damage to the inner wall of the open section, and then it is easy to cause scratches on the surface of the titanium wire. Summary of the invention

[0006] In response to the above-mentioned problems, the present application aims to provide an inner wall cleaning device for a titanium wire drawing die, which can clamp both the drawing die and the grinding equipment to be cleaned, and by driving the drawing die to rotate with the arc structure of the arc-shaped open section compared to the grinding equipment, it can more accurately realize the precise cleaning operation of debris adhered to the arc-shaped open section.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: an inner wall cleaning device for a titanium wire drawing die, wherein the inner wall of the drawing die is composed of a straight cylinder section and an arc-shaped open section, and is characterized in that: the inner wall cleaning device includes a first clamping mechanism for assembling the drawing die, and a second clamping mechanism for assembling a grinding device, and the first clamping mechanism drives the drawing die to deflect along the arc of the arc-shaped open section compared to the grinding device.

[0008] Preferably, the first clamping mechanism comprises a base, on which a longitudinal slide rail and a rotating rod are sequentially arranged, and on one side of the rotating rod a clamping cylinder for sleeve-mounting and clamping the wire drawing die is vertically rotatably arranged.

[0009] Preferably, the second clamping mechanism comprises a transverse slide rail arranged on a base on one side of the longitudinal slide rail, and a clamping body for clamping the polishing device is arranged at intervals on the transverse slide rail.

[0010] Preferably, an inclined circumferential surface for driving the drawing die to be axially positioned is provided at the inner bottom of the clamping cylinder.

[0011] The beneficial effect of the present application is that the inner wall cleaning device can assemble the wire drawing die to be cleaned through the first clamping mechanism, and can clamp the grinding equipment through the second clamping mechanism, thereby first solving the problem that during the current cleaning operation, the wire drawing die and the grinding equipment are difficult to fix, which affects the cleaning quality.

[0012] The first clamping mechanism can drive the wire drawing die to deflect along the arc of the arc-shaped open section compared to the grinding device. That is, while ensuring that the grinding device is relatively stationary, the first clamping mechanism can drive the wire drawing die to rotate along the arc structure of the arc-shaped open section compared to the grinding device, thereby more accurately cleaning the debris adhered to the arc-shaped open section.

[0020] 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.

[0021] See attached Figures 1 to 5 The inner wall cleaning device of a titanium wire drawing die is shown in FIG. 1 , wherein the inner wall of the drawing die 1 is composed of a straight tube section 11 and an arc-shaped open section 12. Figure 1 Under the mechanical extrusion of the straight section 11 of the wire drawing die 1, the outer diameter of the titanium wire is reduced, thereby achieving the effect of reducing the diameter of the wire drawing, while the arc-shaped open section 12 facilitates the titanium wire to smoothly penetrate into the wire drawing die 1.

[0022] In order to solve the difficulties currently encountered when manually using tools or grinding equipment to clean the wire drawing die 1, the present application designs an inner wall cleaning device, which includes a first clamping mechanism for assembling the wire drawing die 1, and a second clamping mechanism for assembling the grinding equipment. The wire drawing die 1 to be cleaned can be assembled through the first clamping mechanism, and the grinding equipment can be clamped similarly through the second clamping mechanism, thereby first solving the problem that during the current cleaning operation, both the wire drawing die 1 and the grinding equipment are difficult to fix, thus affecting the cleaning quality.

[0023] Usually, more oxide scale and debris are adhered to the arc-shaped open section 12 of the wire drawing die 1 (such as Figure 6 As shown), the structure there is an arc-shaped structure. Therefore, in order to facilitate the precise cleaning of the debris adhered there, the first clamping mechanism drives the wire drawing die 1 to deflect along the arc of the arc-shaped open section 12 compared to the grinding device. That is, while ensuring that the grinding device is relatively stationary, the first clamping mechanism can drive the wire drawing die 1 to rotate along the arc structure of the arc-shaped open section 12 compared to the grinding device, thereby enabling the precise cleaning operation of the debris adhered to the arc-shaped open section 12 to be achieved more accurately.

[0024] Specifically, Figure 2-3As shown, the first clamping mechanism includes a base 2, on which a longitudinal slide rail 3 and a rotating rod 4 are sequentially arranged, and a clamping cylinder 5 for sleeve-mounting and clamping the wire drawing die 1 is vertically rotatably arranged on one side of the rotating rod 4. Preferably, tightening bolts are provided at intervals on the outer wall of the clamping cylinder 5, such as Figure 3 As shown, after the wire drawing die 1 is sleeved in the clamping barrel 5 (when clamping, the arc-shaped open section 12 is located outside the clamping barrel 5), the wire drawing die 1 is fixed in the clamping barrel 5 by rotating the tightening bolt to contact the surface of the wire drawing die. Figure 2 As shown by the arrow a in the middle, the rotating rod 4 rotates horizontally compared to the longitudinal slide rail 3 ( Figure 2 As shown by arrow b), and the longitudinal sliding of the longitudinal slide rail 3 on the base 2 ( Figure 2 As shown by the middle arrow c), the clamping cylinder 5 that clamps the wire drawing die 1 can be driven from multiple directions to deflect along the arc of the arc-shaped open section 12 compared to the grinding head of the grinding equipment, thereby achieving accurate cleaning of debris adhered to the arc-shaped open section 12.

[0025] Compared with the rotating rod 4, the clamping cylinder 5 can realize vertical rotation. Therefore, during the cleaning process, the inner wall of the arc-shaped open section 12 can be completely polished and cleaned along the circumferential direction by rotating the clamping cylinder 5.

[0026] To facilitate the clamping of grinding equipment, such as Figure 2 As shown, the second clamping mechanism includes a transverse slide rail 6 arranged on the base 2 on one side of the longitudinal slide rail 3, and a clamp body 7 for clamping the grinding device is arranged at intervals on the transverse slide rail 6. The clamp body 7 is preferably a half-hinged structure, which can clamp and fix the grinding device (such as Figure 3 The grinding device is preferably a hand-held grinder, and its driving end can be equipped with grinding heads of different shapes. The grinding device slides on the base 2 through the transverse slide rail 6, and can achieve axial movement compared to the wire drawing die 1, and the straight barrel section 11 can be axially ground.

[0027] In order to improve the grinding quality of the straight tube section 11, it is necessary to ensure the coaxiality of the straight tube section 11 and the grinding head, and to achieve the coaxiality of the clamping cylinder 5 clamping the wire drawing die 1, such as Figure 5 As shown, an inclined circumferential surface 5a is provided at the bottom of the clamping barrel 5 to drive the drawing die 1 to be axially positioned. When clamping, the drawing die 1 is inserted into the clamping barrel 5, and the bottom end of the drawing die 1 is in circumferential contact with the inclined circumferential surface 5a, which can effectively ensure the coaxiality of the drawing die 1 and the clamping barrel 5, and then the coaxial clamping of the drawing die 1 can be achieved by tightening the jacking bolt, so that when the straight barrel section 11 is ground, the grinding quality can be further improved.

[0028] The principle of the present application is: when performing the grinding and cleaning operation of the wire drawing die 1, the wire drawing die 1 is inserted into the clamping cylinder 5, and the bottom end of the wire drawing die 1 is in circumferential contact with the inclined peripheral surface 5a, and then the coaxial clamping of the wire drawing die 1 can be achieved by tightening the top bolt. Then, the grinding device is assembled and tightened through the clamp body 7, and then during the grinding, the grinding device is started, and the clamping cylinder 5 is driven to rotate vertically and horizontally, and slide longitudinally, and cooperate with the lateral sliding of the grinding device, so that the arc grinding and cleaning operation of the arc-shaped open section 12 of the wire drawing die 1 and the axial grinding operation of the straight section 11 can be achieved.

[0029] 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.
