Description
Technical Field
[0001] This utility model belongs to the technical field of rolling metal wire equipment, and in particular relates to a vertical wire-spinning device for low-speed non-ferrous metal wire. Background Technology
[0002] Wire coilers are typically located after finishing mills and are used to bend high-speed wire rods into coils of a certain diameter after rolling. They simultaneously convert the high-speed linear motion of the wire before bending into a low-speed linear motion along the axial direction after coil bending, thus collecting the high-speed wire. Wire coilers generally require very high incoming material speeds, at least 50 m / s, to complete the coiling action. However, for non-ferrous metals such as titanium, tungsten, molybdenum, and high-temperature alloys, due to the inherent characteristics of the materials, the fastest rolling speed from the finishing mill is only a few tens of meters per second, which cannot meet the minimum speed requirements for wire coiling. Forcing the use of wire coilers to collect non-ferrous metal wire rods will result in the following problems:
[0003] 1. Traditional wire drawing machines have high requirements for the speed of incoming materials and cannot be used for drawing and coiling special non-ferrous metal wires such as titanium, tungsten, molybdenum, and high-temperature alloys with low incoming material speed. Due to the problem of slow incoming material speed, traditional wire drawing machines will often experience situations where wire cannot be drawn and steel piles up.
[0004] 2. Due to the excessively fast feeding speed of traditional wire drawing machines, and the characteristics of non-ferrous metal materials, the surface of the non-ferrous metal wire may cool down, and the temperature of the core of the non-ferrous metal wire will soon rise back to the surface of the wire, resulting in insufficient cooling of the wire and affecting the performance of the material.
[0005] Then, as non-ferrous metals such as titanium, tungsten, molybdenum, and high-temperature alloys are used more and more widely in military, defense industries, and high-end core equipment, the types of material specifications required are increasing. Wire rods generally have the problem that the smaller the size, the more difficult it is to collect. Therefore, there is an urgent need to develop low-speed wire rod spinning machines to fill the industry gap and meet market demand. Utility Model Content
[0006] In view of the above-mentioned problems in the prior art, the present invention aims to provide a vertical wire-spinning device for low-speed non-ferrous metal wires, which solves the problem that traditional wire-spinning machines cannot be used for collecting non-ferrous metal wires.
[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0008] A vertical wire feeding device for low-speed non-ferrous metal wire is provided, comprising a wire feeding mechanism, the wire feeding mechanism including a fixed bracket, a spiral guide outer cylinder is fixedly mounted on the fixed bracket, a rotor inner cylinder is rotatably mounted inside the spiral guide outer cylinder, the rotor inner cylinder is coaxially mounted with the spiral guide outer cylinder; a driving component is provided at the top of the fixed bracket to drive the rotor inner cylinder to rotate around its own axis.
[0009] A spiral guide tube is provided on the inner wall of the spiral guide outer cylinder. The rotor inner cylinder is located inside the spiral guide tube. The top end of the spiral guide tube penetrates through the spiral guide outer cylinder. The middle outer wall of the spiral guide tube is fixedly connected to the inner wall of the spiral guide outer cylinder. The bottom end of the spiral guide tube is oriented towards the outer wall of the rotor inner cylinder. A gap larger than the outer diameter of the spiral guide tube is provided between the outer circumference of the rotor inner cylinder and the inner circumference of the spiral guide outer cylinder.
[0010] The basic principle of the vertical wire-spinning device for low-speed non-ferrous metal wire in this invention is as follows: Due to inertia and initial linear velocity, the low-speed non-ferrous metal wire enters the outer cylinder of the spiral guide tube through the top of the spiral guide tube, and is guided to the outer wall of the inner cylinder of the rotor through the bottom of the spiral guide tube. The spiral guide tube causes the low-speed non-ferrous metal wire to rotate downward in a spiral motion. After the non-ferrous metal wire contacts the outer wall of the inner cylinder of the rotor, the rotating inner cylinder of the rotor drives the non-ferrous metal wire to continue to rotate. During the rotation of the non-ferrous metal wire, the wire is wound into coils by gravity and spiral downward motion, thus solving the problem that traditional wire-spinning machines cannot be used for collecting non-ferrous metal wire.
[0011] Furthermore, as a specific arrangement of the driving component, the driving component includes a fixed disk disposed on the top of the fixed bracket, a drive motor disposed on the fixed disk, and a vertical transmission shaft fixedly connected to the output shaft of the drive motor via a coupling; a connecting cylinder is vertically disposed at the center of the inner cylinder of the rotor, and the outer circumferential wall of the connecting cylinder is fixedly connected to the inner circumferential wall of the inner cylinder of the rotor via a connecting circular plate; the bottom end of the transmission shaft passes through the top of the inner cylinder of the rotor and the inner wall of the connecting cylinder and is fixedly connected to the connecting cylinder.
[0012] The drive motor drives the transmission shaft to rotate, and the rotating transmission shaft drives the entire inner cylinder of the rotor to rotate around its own axis through the connecting cylinder.
[0013] Furthermore, a guide pipe is provided on the outside of the spiral guide cylinder. The guide pipe is horizontally arranged along the tangent direction of the spiral guide cylinder. One end of the guide pipe is connected to the wire feeding roller mechanism, and the other end is connected to the top end of the spiral guide tube. The guide pipe is provided to guide the low-speed non-ferrous metal wire in the wire feeding roller mechanism into the spiral guide tube.
[0014] Furthermore, a multi-roller conveyor is installed directly below the inner cylinder of the rotor. After the wire-spinning mechanism completes the wire-spinning operation, the wound wire falls onto the multi-roller conveyor and is transported to the collection point for packaging.
[0015] Furthermore, the multi-roller conveyor is evenly spaced with multiple cooling devices along its conveying direction, located below the multi-roller conveyor. Sufficient cooling of the coiled wire is achieved by controlling the moving speed of the multi-roller conveyor to increase the spacing between each turn of the coiled wire and by controlling the airflow speed of the cooling devices. At the same spinning speed, the faster the multi-roller conveyor's linear speed, the wider the spacing between each turn of the falling wire, the larger the cooling area, and the easier it is to cool. Conversely, the slower the multi-roller conveyor's linear speed, the narrower the spacing between each turn of the falling wire, the smaller the cooling area, and the longer the cooling time. A larger airflow from the cooling device results in faster cooling, while a smaller airflow results in slower cooling. Sufficient cooling of the material is achieved by matching the linear speed of the multi-roller conveyor and the airflow of the cooling system according to the type of wire.
[0016] Furthermore, a connecting key is vertically provided on the outer circumference of the drive shaft, and a keyway that mates with the connecting key is vertically provided on the inner circumference of the connecting cylinder.
[0017] Furthermore, the bottom of the connecting cylinder is flush with the connecting circular plate, the bottom of the transmission shaft is provided with an external thread and a locking nut is provided thereon, and the upper end face of the locking nut is in close contact with the lower end face of the connecting circular plate.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. This utility model discloses a vertical wire-spinning device for low-speed non-ferrous metal wires. During the collection of low-speed non-ferrous metal wires, the device accelerates and rotates the wires by setting an inner cylinder of a rotor. During the rotation of the non-ferrous metal wires, the wires move downwards by gravity and a spiral, thus completing the wire-spinning and winding action. This solves the problem that traditional wire-spinning machines are not suitable for collecting non-ferrous metal wires.
[0020] 2. This utility model provides a vertical wire-spinning device for low-speed non-ferrous metal wires. By setting up a multi-roller conveyor below the wire-spinning mechanism, the multi-roller conveyor transports the wound wire to the collection point for packaging. Multiple cooling devices below the multi-roller conveyor cool the wound wire, solving the problem of insufficient cooling of wire in traditional wire-spinning machines affecting material properties.

For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.
[0028] like Figures 1-5 As shown, this utility model provides a vertical wire-spinning device for low-speed non-ferrous metal wires, which includes a wire-spinning mechanism 1. The wire-spinning mechanism 1 includes a fixed bracket 11. A spiral guide outer cylinder 12 is vertically fixed on the fixed bracket 11. A rotor inner cylinder 13 is rotatably disposed inside the spiral guide outer cylinder 12. The rotor inner cylinder 13 is coaxially disposed with the spiral guide outer cylinder 12. A driving component 14 is provided at the top of the fixed bracket 11 to drive the rotor inner cylinder 13 to rotate around its own axis.
[0029] A spiral guide tube 15 is provided on the inner wall of the spiral guide outer cylinder 12. The rotor inner cylinder 13 is located inside the spiral guide tube 15. The top end of the spiral guide tube 15 passes through the spiral guide outer cylinder 12. The middle outer wall of the spiral guide tube 15 is fixedly connected to the inner wall of the spiral guide outer cylinder 12. The bottom end of the spiral guide tube 15 is set towards the outer wall of the rotor inner cylinder 13. A gap larger than the outer diameter of the spiral guide tube 15 is provided between the outer circumference of the rotor inner cylinder 13 and the inner circumference of the spiral guide outer cylinder 12.
[0030] Specifically, as one configuration of the driving component 14, the driving component 14 includes a fixed disk 141 mounted on the top of the fixed bracket 11, a drive motor 142 mounted on the fixed disk 141, and a vertical transmission shaft 144 fixedly connected to the output shaft of the drive motor 142 via a coupling 143. A connecting cylinder 131 is vertically mounted at the center of the inner rotor cylinder 13, and the outer circumferential wall of the connecting cylinder 131 is fixedly connected to the inner circumferential wall of the inner rotor cylinder 13 via a connecting circular plate 132. The bottom end of the transmission shaft 144 passes through the top of the inner rotor cylinder 13 and the inner wall of the connecting cylinder 131 and is fixedly connected to the connecting cylinder 131. The drive motor 142 drives the transmission shaft 144 to rotate, and the rotating transmission shaft 144 drives the entire inner rotor cylinder 13 to rotate around its own axis via the connecting cylinder 131.
[0031] Specifically, as a detailed connection method between the drive shaft 144 and the connecting cylinder 131, a connecting key is vertically provided on the outer circumference of the drive shaft 144, and a keyway that mates with the connecting key is vertically provided on the inner circumference of the connecting cylinder 131. The bottom of the connecting cylinder 131 is flush with the connecting circular plate 132, and the bottom of the drive shaft 144 is provided with an external thread and a locking nut 145 is provided thereon. The upper end face of the locking nut 145 abuts against the lower end face of the connecting circular plate 132, thereby fixing the drive shaft 144 and the connecting cylinder 131 together.
[0032] like Figure 3 As shown, preferably but not limited to, a guide pipe 16 is provided on the outside of the spiral guide outer cylinder 12. The guide pipe 16 is horizontally arranged along the tangential direction of the spiral guide outer cylinder 12. One end of the guide pipe 16 is connected to the wire feeding roller mechanism 2, and the other end is connected to the top end of the spiral guide tube 15. The guide pipe 16 is provided to guide the low-speed non-ferrous metal wire in the wire feeding roller mechanism 2 into the spiral guide tube 15.
[0033] like Figure 1 As shown, a multi-roller conveyor 3 is arranged directly below the inner cylinder 13 of the rotor. After the wire-spinning mechanism 1 completes the wire-spinning operation, the wound wire falls onto the multi-roller conveyor 3 and is transported to the collection point for packaging.
[0034] The multi-roller conveyor 3 is evenly spaced with multiple cooling devices 4 along its conveying direction, located below the multi-roller conveyor 3. Sufficient cooling of the coiled wire is achieved by controlling the moving speed of the multi-roller conveyor 3 to increase the spacing between each turn of the coiled wire and by controlling the airflow speed of the cooling devices 4. At the same spinning speed, the faster the multi-roller conveyor 3 moves, the wider the spacing between each turn of the falling wire, resulting in a larger cooling area and easier cooling. Conversely, the slower the multi-roller conveyor 3 moves, the narrower the spacing between each turn of the falling wire, resulting in a smaller cooling area and a longer cooling time. A larger airflow from the cooling devices 4 leads to faster cooling, while a smaller airflow leads to slower cooling. The linear speed of the multi-roller conveyor and the airflow of the cooling devices are matched according to the type of wire to achieve sufficient material cooling.
[0035] When collecting low-speed non-ferrous metal wire in coils, the low-speed non-ferrous metal wire enters the spiral guide tube 15 through the wire feeding roller mechanism 2 and the guide pipe 16. Due to inertia and initial linear velocity, the low-speed non-ferrous metal wire enters the spiral guide outer cylinder 12 through the top of the spiral guide tube 15, and is guided to the outer wall of the rotor inner cylinder 13 through the bottom of the spiral guide tube 15. The spiral guide tube 15 causes the low-speed non-ferrous metal wire to make a downward spiral motion. After the non-ferrous metal wire contacts the outer wall of the rotor inner cylinder 13, the rotating rotor inner cylinder 13 drives the non-ferrous metal wire to continue to rotate. During the rotation of the non-ferrous metal wire, the winding action of the non-ferrous metal wire is completed by gravity and spiral downward motion, which solves the problem that traditional winding machines cannot be used for collecting non-ferrous metal wire. The multi-roller conveyor 3 below the spinning mechanism 1 transports the wound coiled wire to the collection point for packaging. During the conveying of the coiled wire, multiple cooling devices 4 below the multi-roller conveyor 3 cool the wound coiled wire, solving the problem of insufficient cooling of wire in traditional spinning machines affecting material performance.
