Description

Technical Field

[0001] This utility model relates to the technical field of wire drawing machine components, specifically a wire drawing mechanism for an automatic wire drawing machine. Background Technology

[0002] A wire drawing machine is a device for processing metal materials. Through a series of extrusion, stretching, and shrinking actions, it processes metal billets into metal wires of ideal shapes and sizes. In this process, the metal billet is first heated to a certain temperature, then stretched through a die, and finally its size and shape are adjusted through the shrinking zone.

[0003] For example, an existing paper with publication number CN100377801C discloses a wire drawing machine for metal materials, specifically a transmission mechanism, a wire drawing mechanism, a gear rotating housing, and a water tank. The wire drawing mechanism includes four pulley shafts, four transition shafts, and one constant speed pulley shaft. The two ends of each pulley shaft, transition shaft, and constant speed pulley shaft are fixed to the gear rotating housing by bearings, and the pulley shafts and transition shafts are arranged at intervals. The constant speed pulley shaft is located at one end of the gear rotating housing, and a constant speed wheel is fixed at one end of the constant speed pulley shaft. The water tank contains four pulleys and two mold frames. The four pulleys are respectively fixed to one end of the four pulley shafts, and the two mold frames are fixed on the gear rotating housing and located between the pulley shafts. The transmission mechanism, pulley shafts, transition shafts, and constant speed pulley shaft are meshed together by several gears, and the pulleys have a double-section structure with two sections of different diameters.

[0004] Existing wire drawing machines have high friction between the metal blank and the die during operation and lack lubrication. The metal blank will encounter greater resistance when passing through the die, resulting in a decrease in wire drawing speed and a higher risk of the metal blank breaking. To address this, we propose a wire drawing mechanism for an automatic wire drawing machine. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention discloses a wire drawing mechanism for an automatic wire drawing machine, comprising a base 1. Two spaced-apart conveyor rollers 2 are positioned above one end of the base 1. A connecting shaft 3 is fixedly mounted on each conveyor roller 2, and the connecting shaft 3 is rotatably mounted on the base 1. A drive mechanism connected to the two connecting shafts 3 is mounted on the base 1, and the drive mechanism drives the two conveyor rollers 2 to rotate. A vertical plate 4 is fixedly connected to the other end of the base 1. A mold 5 is fixedly mounted inside the vertical plate 4. An annular cavity 6 is formed inside the mold 5. Multiple oil drain holes 7 arranged in a circumferential array are formed on the inner wall of the mold 5, and all oil drain holes 7 communicate with the annular cavity 6. A vertical pipe 8 is fixedly mounted on the vertical plate 4, with its lower end communicating with the annular cavity 6. A block 9 is fixedly mounted on the upper end of the vertical pipe 8. A piston 10 is located inside the vertical pipe 8, and a guide rod 11 is fixedly mounted on the piston 10. The upper end of the guide rod 11 passes through the block 9. An oil injection pipe 12 is connected and fixedly mounted on one side of the vertical pipe 8.

[0026] A spring 13 is fitted on the guide rod 11. The two ends of the spring 13 are fixed to the piston 10 and the block 9, respectively. A magnet 14 is fixed to the top of the guide rod 11. A bracket 15 is fixed on the vertical plate 4. An electromagnet 16 opposite to the magnet 14 is fixed to the top of the bracket 15.

[0027] Pulling the guide rod 11 moves the piston 10 upward, ensuring that the piston 10 does not block the oil injection pipe 12. Lubricating oil is then injected into the vertical pipe 8 through the oil injection pipe 12, and the lubricant is loaded into the annular cavity 6. The metal billet is first heated by the heating device of the wire drawing machine. Then, one end of the metal billet is manually passed through the mold 5, and then through two conveyor rollers 2, before being drawn by the device. The drive mechanism rotates the two conveyor rollers 2, which pull the metal billet to one side. Simultaneously, the electromagnet 16 is energized and applies a repulsive force to the magnet 14. The piston 10 moves downward and pressurizes the annular cavity 6. Lubricating oil can be discharged through multiple oil drain holes 7, thus adding lubricating oil between the metal billet and the mold 5, providing lubrication. When the wire drawing speed is high, the pressurization of the piston 10 accelerates the discharge rate of the lubricating oil. The wire drawing speed can be adapted by adjusting the magnetic force of the electromagnet 16.

[0028] The drive mechanism includes two driven wheels 17, which are fixedly connected to the ends of the connecting shaft 3. Two meshing transmission wheels 18 are rotatably mounted on the base 1. The two transmission wheels 18 are located between the two driven wheels 17 and are meshed with the driven wheels 17 on the same side. A first motor 19 is fixed on the base 1, and the output shaft of the first motor 19 is fixedly connected to the connecting shaft 3 above.

[0029] The first motor 19 drives the connecting shaft 3 to rotate, which in turn drives the conveyor roller 2 on one side to rotate. In conjunction with the transmission action of the two drive wheels 18 and the two driven wheels 17, the two conveyor rollers 2 can rotate synchronously but in opposite directions. Thus, the two conveyor rollers 2 can pull the metal wire to move.

[0030] A ring-shaped container 20 is rotatably mounted on the base 1, located on one side of the mold 5. The inner side of the ring-shaped container 20 has several drainage holes 21 arranged in a circular array. A water tank 22 is fixedly mounted on the base 1, with a water inlet. A miniature water pump 23 is fixedly mounted on the water tank 22, with its inlet pipe connected to the water tank 22. A flexible hose 24 is connected to and fixedly mounted at the outlet of the miniature water pump 23, with the other end of the hose 24 connected to the ring-shaped container 20.

[0031] The metal wire passes through mold 5 and then through an annular container 20. A water tank 22 contains cooling water, which is pumped through a micro water pump 23 into a hose 24. The water then enters the annular container 20 and is finally sprayed out through multiple drain holes 21. The water sprays onto the metal wire, thus cooling it after drawing. During the drawing process, the metal wire generates a large amount of heat due to deformation. If not cooled in time, the wire's material properties may deteriorate, such as softening or reduced strength. Cooling effectively prevents these problems, ensuring the metal wire retains its original excellent properties.

[0032] A guide groove 25 is fixedly installed on the top of the water tank 22. The guide groove 25 is located between the annular container 20 and the two conveying rollers 2. The metal wire is placed on the guide groove 25 and guided by the guide groove 25.

[0033] Working principle: Pulling the guide rod 11 moves the piston 10 upward, ensuring that the piston 10 does not block the oil injection pipe 12. Lubricating oil is then injected into the vertical pipe 8 through the oil injection pipe 12, and the lubricant is loaded into the annular cavity 6. The metal billet is first heated by the heating device of the wire drawing machine. Then, one end of the metal billet is manually passed through the mold 5, then through two conveyor rollers 2, and finally through the device for wire drawing. The two conveyor rollers 2 are rotated by the drive mechanism.

[0034] The first motor 19 drives the connecting shaft 3 to rotate, which in turn drives the conveyor roller 2 on one side to rotate. In conjunction with the transmission action of the two drive wheels 18 and the two driven wheels 17, the two conveyor rollers 2 can rotate synchronously but in opposite directions. Thus, the two conveyor rollers 2 can pull the metal wire to move.

[0035] Two conveyor rollers 2 pull the metal blank to one side, while the electromagnet 16 is energized and applies a repulsive force to the magnet 14. The piston 10 moves down and pressurizes the annular cavity 6. Lubricating oil can be discharged through multiple oil drain holes 7, thereby adding lubricating oil between the metal blank and the mold 5, which can play a lubricating role.

[0036] The metal wire passes through the mold 5 and then through the annular container 20. The water tank 22 contains cooling water. The water is introduced into the hose 24 by the micro water pump 23, and then enters the annular container 20. Finally, it is sprayed out from multiple drain holes 21. The water can be sprayed onto the metal wire, thereby cooling the drawn metal wire.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
