Description
Technical Field
[0001] This utility model belongs to the field of wire drawing machines, specifically relating to a multi-wheel variable diameter wire drawing machine. Background Technology
[0002] Wire drawing machines change the diameter of metal wires through a drawing process to achieve the desired diameter. During the drawing process, it is important to avoid excessive diameter changes that could cause cracks or breakage of the metal wires, and to ensure that the drawn wires have good strength and hardness. This requires the metal wires to be drawn through multiple sets of drawing dies, gradually reducing their diameter. Traditional wire drawing equipment usually consists of drawing dies arranged in a front-to-back sequence, with the wire drawing path being a straight line. This results in excessively large dimensions of the wire drawing equipment, requiring a significant amount of space in the factory, and causing high production, transportation, and assembly costs. Utility Model Content
[0003] In order to solve the problems existing in the prior art, the present invention provides a multi-wheel variable diameter wire drawing machine, which can effectively reduce the size and floor space of the wire drawing machine, reduce the equipment cost of wire drawing, and also help improve wire drawing efficiency and product quality.
[0004] The specific technical solution adopted in this utility model is as follows:
[0005] A multi-wheel variable diameter wire drawing machine includes a wire drawing assembly and a cooling device. The metal wire is output from the unwinding reel and is wound by the winding assembly after passing through the wire drawing assembly. The wire drawing assembly is cooled by the cooling device. The key feature is that the wire drawing assembly includes a wire drawing die and a pair of spaced-apart rollers. The rollers are parallel in axis and face the same direction. The metal wire is reciprocated and wound around the two rollers to form multiple turns of metal wire. Each turn of metal wire passes through a wire drawing die. The wire drawing die is supported by a die box.
[0006] The winding assembly includes a drive roller, a J-shaped drum, and an annular storage cavity arranged sequentially along the height direction. The J-shaped drum has the freedom to rotate around its own vertical axis by means of a motor. The metal wire is output from the drawing die, passes through the drive roller and the J-shaped drum in sequence, and is output from the J-shaped drum and falls into the storage cavity.
[0007] The wire drawing die and winding assembly are also provided with a guide wheel group, which includes a first wheel, a second wheel and a third wheel. The first wheel and the second wheel are arranged adjacent to each other. After the wire is output from the wire drawing die, the metal wire is reciprocated and wound around the first wheel and the second wheel to form a multi-turn conveying path. After the metal wire is output from the multi-turn conveying path, it passes through the third wheel and is conveyed to the drive rollers. A tensioning wheel is also provided between the third wheel and the drive rollers.
[0008] The cooling device includes a cooling tank, an inlet pipe, and an outlet pipe. The inlet pipe and the outlet pipe are connected by a water pump and form a cooling liquid circulation channel with the cooling tank. The mold box and the tower wheel are respectively located below the inlet pipe. The inlet pipe is provided with water outlet holes facing the mold box and the tower wheel.
[0009] The lower ends of the mold box and the tower wheel are respectively immersed in the coolant in the cooling tank.
[0010] The cooling box is provided with wire-passing holes on both sides. The metal wire is fed to the wire drawing die along the wire-passing hole on one side. After being drawn by the wire drawing die, the metal wire is fed to the winding assembly along the wire-passing hole on the other side.
[0011] A washer is provided inside the wire passage hole, and the metal wire passes through the inner hole of the washer.
[0012] The wire drawing die is arranged in two rows on the die box, and the two rows of wire drawing dies are staggered. The diameter of the die cavity of the two staggered wire drawing dies decreases sequentially along the axial direction of the pulley.
[0013] The beneficial effects of this utility model are:
[0014] This invention employs multiple wire drawing dies arranged on a die box, with rollers on both sides of the die box. The metal wire is repeatedly wound around the two rollers to form multiple loops of metal wire. Each loop of metal wire passes through the die cavity of a wire drawing die. The structure is compact and the layout is reasonable, effectively reducing the length of the wire drawing machine and greatly reducing the floor space occupied by the wire drawing machine in the factory. It can also provide sufficient drawing path for the metal wire and ensure the quality of the product after the metal wire is drawn.
[0015] The wire drawing dies are arranged in two rows on the die box, with the two rows of wire drawing dies interspersed. The diameter of the die cavity of the two interspersed wire drawing dies decreases sequentially along the axial direction of the pulley, further optimizing the spatial layout. This not only extends the drawing path but also allows for more precise control of the wire diameter change process, which helps to improve the working efficiency of the wire drawing machine.
[0016] The metal wire is repeatedly wound around the first and second wheels to form a multi-loop conveying path. The first and second wheels are set vertically at intervals. Without increasing the size of the wire drawing machine, the conveying path of the metal wire is effectively increased, allowing the metal wire to fully contact the air for cooling. It also allows the metal wire to have more contact and adjustment with the first and second wheels, which helps to further stabilize the movement of the metal wire, reduce the shaking and deviation of the metal wire, and further improve the stability of the metal wire during the conveying process.
[0017] During the rotation of the J-shaped drum, its lower end forms a ring path above the storage cavity. The J-shaped drum guides the wire, preventing it from tangling during winding and ensuring that the wire is neatly wound inside the storage cavity, thus improving the quality and aesthetics of winding.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0024] Specific implementation examples Figure 1 , Figure 2 As shown, this utility model relates to a multi-wheel variable diameter wire drawing machine, including a wire drawing assembly and a cooling device. The metal wire 2 is output from the unwinding reel and, after passing through the wire drawing assembly, is wound by the winding assembly. The wire drawing assembly is cooled by the cooling device. The wire drawing assembly, cooling device, and winding assembly are all mounted on a frame. Crucially, the wire drawing assembly includes a wire drawing die 1 and a pair of spaced-apart rollers 4. The rollers 4 are axially parallel and oriented in the same direction. Figure 4 As shown, the metal wire 2 is repeatedly wound around the wire guide 5 of the two tower wheels 4 to form multiple turns of metal wire 2. Each turn of metal wire 2 passes through a wire drawing die 1. The wire drawing die 1 is supported by a die box 3. A set of wire guide grooves 5 are provided on the tower wheel 4. The diameter of the wire guide grooves 5 gradually increases along the axial direction of the tower wheel 4, while the diameter of the die cavity of the wire drawing die 1 gradually decreases along the axial direction of the tower wheel 4.
[0025] In this embodiment, the wire drawing dies 1 are arranged in parallel, and the axial direction of the die cavity of the wire drawing die 1 is perpendicular to the axial direction of the pulley 4.
[0026] The drawing path is as follows: during the drawing process, the metal wire 2 is conveyed from the left side of the die box 3 to the right through the cavity of a wire drawing die 1, and continues to be conveyed to the right from the cavity of the wire drawing die 1. The metal wire 2 contacts and is guided by the wire guide groove 5 above the tower wheel 4 on the right side of the die box 3. Then, the metal wire 2 winds around to the bottom of the tower wheel 4 on the right side of the die box 3 and is conveyed to the tower wheel 4 on the left side of the die box 3 from the bottom of the tower wheel 4 on the left side of the die box 3. The metal wire 2 winds around to the top of the tower wheel 4 from the wire guide groove 5 below the tower wheel 4 on the left side of the die box 3 and continues to be conveyed to the next wire drawing die 1 until the metal wire 2 is drawn to the required diameter and then conveyed to the winding assembly and wound up by the winding assembly.
[0027] The mold box 3 is equipped with tower wheels 4 on both sides, and multiple wire drawing dies 1 are centrally arranged on the mold box 3. This effectively reduces the length of the wire drawing machine, greatly reduces the floor space occupied by the wire drawing machine in the factory, and can also provide sufficient drawing path for the metal wire 2, thereby improving the product quality of the drawn metal wire 2.
[0028] This utility model installs multiple wire drawing dies 1 on the die box 3, which facilitates centralized management, installation and maintenance of the wire drawing dies 1 by the staff, and helps to improve the overall structural compactness of the wire drawing machine.
[0029] The wire drawing dies 1 are arranged in two rows on the die box 3, with the two rows of dies 1 staggered. The diameter of the die cavities of the two staggered rows of dies 1 decreases sequentially along the axial direction of the pulley 4. That is, two dies 1 with similar diameters are located in the two rows respectively. For example, dies 1 with large, medium and small cavity diameters are located in one row, and dies 1 with medium diameter cavities are located in the other row. Furthermore, in the axial projection of the pulley 4, dies 1 with medium diameter cavities are located between dies 1 with large and small diameter cavities. The staggered arrangement of the two rows further optimizes the arrangement of the dies 1, further optimizes the spatial layout, and improves the utilization of space. More dies 1 with different diameter cavities can be set in a limited space, which not only further extends the drawing path, but also allows for more precise control of the diameter change process of the metal wire 2, thus helping to improve the working efficiency of the wire drawing machine.
[0030] like Figure 1As shown, the wire drawing die 1 and the winding assembly are also equipped with guide wheel sets. After the metal wire 2 is drawn to the required diameter, it is guided by the guide wheel sets during its conveying to the winding assembly. The metal wire 2 first passes through the first wheel 10 and then is conveyed to the second wheel 11. After being guided by the second wheel 11, it passes through the first wheel 10 and the second wheel 11 again. Subsequently, the metal wire 2 passes through the first wheel 10 and is conveyed to the third wheel 12. In this embodiment, the metal wire 2 forms two conveying paths on the first wheel 10 and the second wheel 11. The first wheel 10 and the second wheel 11 are vertically spaced. Without increasing the size of the wire drawing machine, the conveying path of the metal wire 2 is effectively increased, allowing the metal wire 2 to fully contact the air for cooling. It also allows the metal wire 2 to have more contact and adjustment with the first wheel 10 and the second wheel 11, which helps to further stabilize the movement of the metal wire 2, reduce the shaking and deviation of the metal wire 2, and further improve the stability of the metal wire 2 during the conveying process.
[0031] After passing through the first round 10 and the second round 11, the metal wire 2 is sequentially fed to the third round 12 and the winding assembly.
[0032] Preferably, the winding assembly includes a drive roller 6, a J-shaped drum 7, and a storage box 8 arranged sequentially along the height direction. The upper end of the J-shaped drum 7 is fixedly connected to the turntable, which is hinged to the frame. The turntable has the freedom to rotate around its own axis on the frame. The vertical axis of the J-shaped drum 7 is coaxial with the axis of the turntable. A motor drives the turntable to rotate on the frame, and the rotation of the turntable carries the J-shaped drum 7 along with it. This winding assembly makes reasonable use of three-dimensional space, which helps to further reduce the floor space of the wire drawing machine.
[0033] The storage box 8 has an annular storage cavity 9. After passing through the third wheel 12, the metal wire 2 passes through the drive roller 6 and the J-shaped drum 7 in sequence. A guide drum is set on the frame between the drive roller 6 and the turntable. The metal wire 2 conveyed by the drive roller 6 passes through the frame and enters the J-shaped drum 7 through the guide drum. The drive roller 6 drives the metal wire 2 to continuously convey into the J-shaped drum 7. The J-shaped drum 7 rotates around its own vertical axis with the help of a motor. The lower end of the J-shaped drum 7 is the output end. During the rotation of the J-shaped drum 7, its lower end forms an annular path above the storage cavity 9. The J-shaped drum 7 guides the metal wire 2 to avoid tangling during the winding process, ensuring that the metal wire can be neatly wound in the storage cavity 9, thus improving the winding quality and aesthetics.
[0034] As the J-shaped drum 7 rotates, the metal wire 2 is output from the output end of the J-shaped drum 7 in a circular path to the annular receiving cavity 9, and the metal wire 2 is wound around the inner diameter of the receiving cavity 9.
[0035] On the other hand, the rotation speed of the J-type drum 7 can be flexibly adjusted by controlling the motor according to different metal wire materials and winding speed requirements, thereby improving the adaptability of the wire drawing machine.
[0036] Preferably, a tensioning wheel 13 is also provided between the third wheel 12 and the drive roller 6. The tensioning wheel 13 is positioned above the metal wire 2 and provides a downward force to the metal wire 2, so that the metal wire 2 and the drive roller 6 can form effective contact, thereby ensuring the accuracy and stability of winding.
[0037] like Figure 1 , Figure 2 As shown, the cooling equipment includes a cooling tank 14, an inlet pipe 15, and an outlet pipe 16. The inlet pipe 15 and the outlet pipe 16 are connected by a water pump and form a cooling liquid circulation channel with the cooling tank 14. The die box 3 and the roller 4 are respectively located below the inlet pipe 15. The inlet pipe 15 is provided with water outlet holes 17 facing the die box 3 and the roller 4. The coolant is poured onto the die box 3 and the roller 4 along the water outlet holes 17 on the inlet pipe 15 to cool the die box 3 and the roller 4, preventing the temperature from becoming too high due to prolonged operation, which would affect the service life and drawing quality of the wire drawing die 1. The coolant in the cooling tank 14 is drawn by the water pump and passes through the outside of the cooling tank 14 along the outlet pipe 16 to cool the coolant, thereby ensuring that the coolant discharged from the inlet pipe 15 and the coolant in the cooling tank 14 always maintain a low temperature, effectively cooling the wire drawing die 1 and the roller 4.
[0038] The lower ends of the mold box 3 and the tower wheel 4 are immersed in the coolant in the cooling tank 14, so that the mold box 3 and the tower wheel 4 are in full contact with the coolant, improving the heat exchange efficiency, rapidly reducing the temperature of the mold box 3 and the tower wheel 4, and enhancing the cooling effect on the mold box 3 and the tower wheel 4.
[0039] like Figure 3 As shown, the cooling box 14 is provided with wire passage holes 18 on both sides. The metal wire 2 is fed to the wire drawing die 1 along the wire passage hole 18 on one side. After being drawn by the wire drawing die 1, the metal wire 2 is fed to the winding assembly along the wire passage hole 18 on the other side. The metal wire 2 enters and exits the cooling box 14 through the wire passage hole 18 to prevent the metal wire 2 from deviating and affecting the conveying and drawing effect.
[0040] Preferably, a washer 19 is provided inside the wire passage hole 18. The metal wire 2 passes through the inner hole of the washer 19. The washer 19 can reduce the friction on the metal wire 2 and protect the surface of the metal wire 2 from damage.
