Description

Technical Field

[0001] The utility model belongs to the technical field of diamond wire production, and particularly relates to a cleaning mechanism for diamond wire drawing. Background Art

[0002] At present, during the production of diamond wire, the steel wire passes through the die core of a wet drawing machine and then exits. There is vibration, and it is necessary to wipe its surface with a felt pad to ensure the stability of the diamond wire after drawing, avoid vibration, and ensure the surface smoothness of the diamond wire.

[0003] Currently, most of the steel wires wipe the felt pad by passing through the middle of the felt pad after passing through the die core. On the one hand, the circumferential contact between the felt pad and the diamond wire poses a risk of breaking it. On the other hand, the fixed position of the felt pad is not convenient to adjust, so it is impossible to ensure the best position of the felt pad when replacing or installing the felt pad. Summary of the Invention

[0004] The utility model aims to solve the problems that in the existing wet drawing felt pad for diamond wire production, the circumferential contact between the felt pad and the diamond wire causes a large resistance to the diamond wire, there is a risk of breakage, and the position of the felt pad is not convenient to adjust according to the position of the diamond wire. The utility model provides a cleaning mechanism for diamond wire drawing. By adjusting the installation position of the felt pad during the installation of the felt pad fixing device, and through the inserted felt pad, when the diamond wire shakes or vibrates, the felt pad rotates around the connecting rod along with the diamond wire, thereby ensuring the surface smoothness of the diamond wire, ensuring the contact between the diamond wire and the felt pad, and ensuring the cleaning effect of the diamond wire.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A cleaning mechanism for diamond wire drawing is arranged on the die holder of a wet drawing machine and is used to clean the surface of the drawn steel wire. A die core is embedded in the die holder. A felt pad fixing device is arranged on the die holder. A connecting rod is fixedly arranged on the felt pad fixing device. A felt pad is inserted into the connecting rod. The steel wire contacts the bottom surface of the felt pad after extending out of the die core. The installation position of the felt pad is adjusted through the felt pad fixing device, and the felt pad is inserted and installed through the connecting rod. Furthermore, the felt pad can rotate around the connecting rod.

[0007] Preferably, the felt pad fixing device includes a first mounting shaft, a second mounting shaft and a connecting plate. One end of the first mounting shaft is detachably connected to the mold base, and the other end is fixedly provided with the connecting plate. Strip-shaped holes and screw holes are respectively formed at both ends of the connecting plate. The first mounting shaft passes through the strip-shaped holes, the second mounting shaft penetrates and is fixedly sleeved in the screw holes, an annular ring is fixedly sleeved on the second mounting shaft, one end of the connecting rod is fixedly connected to the side of the annular ring, and the other end is tapered and inserted with a felt pad. When the first mounting shaft is installed on the mold base, the position of the connecting rod can be adjusted and the position of the connecting rod can be ensured to be fixed. And when the annular ring is installed, the position of the connecting rod is further adjusted and fixed to ensure that the installation position of the felt pad is accurately fixed.

[0008] Preferably, the first mounting shaft includes a first screw rod, an intermediate shaft, a limiting shaft and a second screw rod which are fixedly connected in sequence. The connecting plate is sleeved on the limiting shaft, and the limiting shaft matches the strip-shaped hole. A first nut is threadedly connected to the second screw rod. The connecting plate is located between the intermediate shaft and the first nut. The connection between the first mounting shaft and the mold base is realized through the first screw rod, the relative position between the felt pad and the steel wire is ensured through the connecting plate, and the fixed connection between the connecting plate and the first mounting shaft is realized through the first nut.

[0009] Preferably, the second mounting shaft includes a third screw rod, a connecting shaft and a fourth screw rod which are fixedly connected in sequence. The third screw rod is threadedly connected to the connecting plate through the screw hole. The annular ring is sleeved on the connecting shaft. A second nut is threadedly connected to the fourth screw rod. The annular ring is located between the connecting plate and the second nut. The fastening connection between the second mounting shaft and the connecting plate is realized through the third screw rod, and the fixation of the annular ring is realized through the second nut, thereby realizing the fixation of the connecting rod.

[0010] Preferably, the second screw rod and the limiting shaft together form a thrust bolt, and the third screw rod and the connecting shaft, and the fourth screw rod and the connecting shaft respectively form two anti-loosening bolts to ensure the fixing effect of the connecting plate and the annular ring, avoid the angle deviation of the connecting rod, and further affect the wiping effect of the felt pad on the steel wire.

[0011] Preferably, the first screw rod is threadedly connected to the mold base and fixed by a third nut to ensure the fixing effect after adjusting the installation position of the first screw rod.

[0012] Through the above technical solutions, the beneficial effects of the present utility model are:

[0013] 1. The utility model adjusts the installation position of the felt pad during the installation process of the felt pad, and then ensures the fixation of the position of the connecting rod through the fixed installation of the first installation shaft, the second installation shaft, the connecting plate, the annular ring, etc., thereby ensuring the relative position between the felt pad inserted on the connecting rod and the drawn steel wire, effectively avoiding the angular change of the connecting rod and driving the inclination of the felt pad, which affects the cleaning effect of the steel wire surface.

[0014] 2. The utility model inserts and installs the felt pad at the end of the connecting rod, and then the drawn steel wire contacts the bottom surface of the felt pad. On the one hand, the felt pad can rotate around the connecting rod, and then the felt pad rotates according to the vibration of the steel wire to ensure its full contact with the steel wire. On the other hand, the contact between the felt pad and the steel wire is not circumferential, avoiding excessive resistance resulting in the fracture of the steel wire; thus effectively avoiding the influence of the vibration and shaking of the steel wire, and ensuring the wiping effect on the surface of the steel wire and the smoothness of the steel wire surface.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the utility model in conjunction with the drawings and the specific embodiments:

[0023] As Figures 1 to 6As shown in the figure, this embodiment provides a cleaning mechanism for diamond wire drawing, which is arranged on the die holder 1 of a wet drawing machine and is used to clean the surface of the steel wire after drawing. A die core is embedded in the die holder 1, and the steel wire is drawn through the die core. A felt pad fixing device is arranged on the die holder 1. The felt pad fixing device includes a first mounting shaft, a second mounting shaft, and a connecting plate 4. One end of the first mounting shaft is detachably connected to the die holder 1, and the other end is fixedly provided with the connecting plate 4. The first mounting shaft includes a first screw 8, an intermediate shaft 9, a limiting shaft 10, and a second screw 11 that are fixedly connected in sequence. The first screw 8 is threadedly connected to the die holder 1 and is fixed by a third nut 17. Rotating the first screw 8 makes the first mounting shaft threadedly connected to the die holder 1. When the installation is completed and the first mounting shaft is rotated until the connecting rod 2 reaches the corresponding installation position, rotate the third nut 17 threadedly connected to the first screw 8 to achieve the fixed locking of the first mounting shaft and the die holder 1.

[0024] Bar-shaped holes 5 and screw holes 6 are respectively formed at both ends of the connecting plate 4. The first mounting shaft passes through the bar-shaped hole 5. The limiting shaft 10 is sleeved with the connecting plate 4, and the limiting shaft 10 matches the bar-shaped hole 5. A first nut 12 is threadedly connected to the second screw 11. The connecting plate 4 is located between the intermediate shaft 9 and the first nut 12. The second screw 11 and the limiting shaft 10 together form a thrust bolt, and the connecting plate 4 is fixedly connected to the first mounting shaft through the first nut 12.

[0025] The second mounting shaft penetrates and is fixedly sleeved in the screw hole 6. An annular ring 7 is fixedly sleeved on the second mounting shaft. The second mounting shaft includes a third screw 13, a connecting shaft 14, and a fourth screw 15 that are fixedly connected in sequence. The third screw 13 and the connecting shaft 14, and the fourth screw 15 and the connecting shaft 14 respectively form two anti-loosening bolts. The third screw 13 is threadedly connected to the connecting plate 4 through the screw hole 6 to achieve the fixation of the second mounting shaft and the connecting plate 4. The annular ring 7 is sleeved on the connecting shaft 14. A second nut 16 is threadedly connected to the fourth screw 15. The annular ring 7 is located between the connecting plate 4 and the second nut 16. The annular ring 7 is locked and fixed through the second nut 16. Furthermore, by using the thrust bolt, the angle or position deviation of the connecting rod 2 during use can be effectively avoided.

[0026] A connecting rod 2 is fixedly arranged on the felt pad fixing device. The connecting rod 2 is at the same height as the center of the die core. The connecting rod 2 is inserted with a felt pad 3. After the steel wire extends out of the die core, it bypasses the lower side of the felt pad 3 and contacts the lower side surface of the felt pad 3. The inserted felt pad 3 is convenient to automatically adjust the rotation according to the vibration of the steel wire to ensure adaptation to the steel wire. One end of the connecting rod 2 is fixedly connected to the side part of the annular ring 7, and the other end is tapered and inserted with the felt pad 3, that is, the connecting rod 2 is needle-shaped. The connecting rod 2 and the annular ring 7 can be fixed by welding. During installation, the annular ring 7 is rotated until the connecting rod 2 is at the same height as the central axis of the die core, and then the second nut 16 is rotated to lock and fix the annular ring 7. The felt pad 3 is inserted on the tapered tip of the connecting rod 2, and thus the felt pad 3 can rotate circumferentially around the connecting rod 2. The steel wire extends out of the die core and contacts the bottom surface of the felt pad 3, effectively wiping the lubricating fluid and the like on the surface of the steel wire after drawing, and ensuring the smoothness of the surface of the steel wire after drawing through the felt pad 3.

[0027] During use, first connect and fix the connecting plate 4 to the first mounting shaft and the second mounting shaft. Then rotate the first mounting shaft to thread the first screw rod 8 with the die holder 1 until the connecting plate 4 is in a vertical state. Rotate the third nut 17 to tighten it against the die holder 1 to fix the first mounting shaft. Then rotate the annular ring 7 to make the connecting rod 2 at the same height as the central axis of the die core. Rotate the second nut 16 to lock and fix the annular ring 7, and thus fix the connecting rod 2. Insert the felt pad 3 on the connecting rod 2, and make the drawn steel wire extending out of the die core contact the lower side of the felt pad 3.
