Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cable manufacturing, and in particular to a wire taking-up device and a wire taking-up method. Background Art
[0002] In the manufacturing process of electrical round aluminum / copper rods, after the aluminum / copper conductors are formed by continuous casting and rolling, the continuously produced aluminum / copper rods need to be wound into standard coils through the coiling process. The quality of the coiling directly affects the processing efficiency of the subsequent wire drawing process and the conductive properties of the finished cable. The existing coiling process generally uses a wire dispenser and a flower basket type wire take-up basket as the core equipment. Its working principle is to drive the wire dispenser to rotate through a motor to wind the aluminum / copper rod into a coil in the take-up frame.
[0003] In the traditional winding process, the wire disengagement device usually rotates at the same eccentric angle with the center of the wire basket as the rotation axis. This will cause concentric circle stacking during the wire winding process. The inner circle wire is wrapped by the outer layer wire to form a thermal barrier, resulting in an interlayer temperature difference of about 40℃ to 50℃, causing non-uniform phase change in the metallographic structure of the aluminum rod, which directly affects key performance parameters such as resistivity, tensile strength and elongation.
[0004] In order to avoid the formation of concentric circles in the wire coil, the prior art usually adopts the method of intermittent large and small coils to improve the heat dissipation capacity of the coil during the winding process. However, the intermittent large and small coils are prone to disorderly arrangement of the rods, which not only increases the difficulty of bundling, but also causes the problem of wire drawing when releasing the wire in the subsequent process. Summary of the invention
[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a wire taking-up device and a wire taking-up method, which can solve the problems of poor heat dissipation, difficult bundling and easy wire drawing in the subsequent wire release in the coil stacking method in the prior art.
[0006] In order to achieve the above purpose and other purposes, the present invention is implemented by including the following technical solutions: As a first aspect, the present invention proposes a wire taking-up device, including a wire outlet, including a first straight pipe section and a second straight pipe section, the first straight pipe section is vertically arranged, and a certain angle is formed between the second straight pipe section and the first straight pipe section; a wire taking-up frame is arranged below the second straight pipe section, and its center line α is not colinear with the center line β of the first straight pipe section; the wire taking-up frame rotates around the center line α, and the rotation direction is opposite to the rotation direction of the wire outlet, and the rotation speed N is less than the rotation speed n of the wire outlet.
[0007] In one embodiment, n:N=200-400.
[0008] In one embodiment, the diameter R of the wire take-up frame does not exceed 3000 mm; the outer diameter of the winding of the aluminum / copper rod coming out of the wire outlet is r=0.65~0.7R; and the distance L between the center line α and the center line β is R / 2-r / 2.
[0009] In one embodiment, the wire take-up frame is disposed below the wire discharging device via a movable frame, and a second driving device is disposed between the wire take-up frame and the movable frame.
[0010] In one embodiment, a plurality of the wire-receiving frames are disposed on the movable frame, and a center line connecting the plurality of the wire-receiving frames is a moving direction of the movable frame.
[0011] In one embodiment, a rope threading groove is provided at the bottom of the wire take-up frame.
[0012] In one embodiment, the plurality of rope threading slots are arranged in a circular array.
[0013] In one embodiment, the wire outlet is rotatably connected to the platform of the fixed frame via a rotating shaft.
[0014] As a second aspect, the present invention also provides a wire-reeling method, in which a wire-discharger rotates at a rotation speed N and a fixed eccentric angle to discharge the wire; a wire-reeling frame synchronously rotates around its center in a direction opposite to that of the wire-discharger, and the rotation speed n is less than the rotation speed N; the rotation center line of the wire-discharger is not colinear with the rotation center line of the wire-reeling frame.
[0015] In one embodiment, each coil of the tying wire roll produced by the wire taking-up method has the same size.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. In the process of wire taking-up, the coils do not overlap each other, which can improve the heat dissipation capacity of the coils in the process. The inner and outer diameters of the bundled wire rolls finally formed are neat, and the coils are of uniform size. Compared with the bundled wire rolls with large and small coils stacked in the intermittent wire-out method, it is easier to bundle and can also avoid the problem of wire drawing during the subsequent wire release. At the same time, the rotation of the wire-taking frame can further improve the heat dissipation of the coils during the wire taking-up process.
[0018] 2. The design of the wire take-up frame diameter, coil outer diameter, and the spacing between the center line α and the center line β of the present invention can ensure that the wire coil formed by the winding does not collapse due to multi-layer stacking during the wire take-up process, and the stacking is more stable, which is more conducive to the subsequent bundling of the wire coils;
[0019] 3. The design of the second driving device of the present invention can provide a stable driving force for the wire take-up frame;
[0020] 4. The design of the mobile frame of the present invention can drive multiple wire-receiving frames to move horizontally, so that when one wire-receiving frame completes wire-receiving, it can be moved and switched to the next wire-receiving frame to reel in the wires. At this time, the wire-receiving frame that has completed wire-receiving can bundle the wires while the next wire-receiving frame is reeling in the wires. Compared with the fixed wire-receiving frame design, it can save the bundling waiting time and improve the work efficiency;
[0021] 5. The design of the rope threading groove of the present invention can facilitate workers to use ropes to bundle the wire coils that have been collected for overall transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 1-Figure 2 As shown, the present invention provides a wire-taking device, including a fixed frame 1-1, a rotating shaft 1-2, a wire-outlet 1-3 and a wire-taking frame 2-1. The fixed frame 1-1 is fixed on the ground; the wire-outlet 1-3 is rotatably connected to the platform of the fixed frame 1-1 through the rotating shaft 1-2. The rotation of the wire-outlet 1-3 can be driven by a first driving device. Specifically, the first driving device can be a motor, which can be connected to the rotating shaft 1-2 through a coupling or connected to the rotating shaft 1-2 through a belt. The wire-outlet 1-3 includes a first straight pipe section and a second straight pipe section, the first straight pipe section is vertically arranged and connected to the rotating shaft 1-2; the second straight pipe section is located below the platform of the fixed frame 1-1, and forms a certain angle with the first straight pipe section, and the angle is determined according to design requirements. The first straight pipe section and the second straight pipe section can be integrally formed, that is, the angle formed by the two is a fixed angle. The angle between the first straight tube section and the second straight tube section can also be an adjustable angle. The adjustable design is only adjusted at the beginning of the wire collection to meet the production needs of a specific coil size, and is not adjusted during the wire collection process. The wire collection frame 2-1 is arranged below the wire outlet 1-3, and its center line α is not colinear with the center line β of the first straight tube section. The wire collection frame 2-1 rotates slowly at its center, and the rotation direction is opposite to that of the wire outlet 1-3. The rotation speed N (r / min) is much smaller than the rotation speed n (r / min) of the wire outlet 1-3. Specifically, n: N = 200 ~ 400.
[0034] The aluminum rod winding track of the wire take-up device provided by the present invention is as follows: Figure 4 and Figure 5 As shown, the coils do not overlap during the process, which can improve the heat dissipation capacity of the coils during the process, and the inner and outer diameters of the final bundled wire rolls are neat (see Figure 6 ), and the coil size is uniform, compared with the bundled wire coils with large and small coils stacked (see Figure 7 ) is easier to bundle and can also avoid the problem of wire drawing during the subsequent wire release. At the same time, the rotation of the wire take-up frame 2-1 can further improve the heat dissipation of the coil during the wire take-up process.
[0035] Furthermore, the diameter of the winding frame 2-1 is R, in mm, and should be designed according to the maximum outer diameter of the aluminum rod coil formed by the equipment, but it is not recommended to exceed 3000 mm. The outer diameter of the coil when the aluminum / copper rod coming out of the outlet 1-3 is evenly wound is r, in mm, and should satisfy r=0.65~0.7R, for example, r=0.67R. The distance between the center line α and the center line β is L, in mm, and should satisfy L=R / 2-r / 2. This design ensures that the coil formed by the winding does not collapse due to multi-layer stacking during the winding process, and the stacking is more stable, which is more conducive to the subsequent bundling of the coils.
[0036] Furthermore, the wire take-up frame 2-1 is arranged below the wire outlet 1-3 through a mobile frame 2-2, and a second driving device 2-3 is arranged between the wire take-up frame 2-1 and the mobile frame 2-2. The second driving device 2-3 may include a motor and a belt, and the motor is connected to the rotating shaft of the wire take-up frame 2-1 through a belt. The design of the second driving device 2-3 can provide a stable driving force for the wire take-up frame 2-1.
[0037] Furthermore, one wire-receiving frame 2-1 may be provided on the movable frame 2-2, or a plurality of (for example, two) wire-receiving frames 2-1 may be provided, and the center line connecting the plurality of wire-receiving frames 2-1 is the moving direction of the movable frame 2-2, so that the movable frame 2-2 can drive the wire-receiving frame 2-1 to move horizontally, so that when one wire-receiving frame 2-1 completes wire-receiving, it moves and switches to the next wire-receiving frame 2-1 to carry out wire-receiving. At this time, the wire-receiving frame 2-1 that has completed wire-receiving can bundle while the next wire-receiving frame 2-1 is winding up. Compared with the fixed wire-receiving frame design, it can save the bundling waiting time and improve the work efficiency.
[0038] Furthermore, if Figure 3 As shown, in order to facilitate the bundling of the completed wire coils, a plurality of rope threading grooves 2-4 can be set at the bottom of the wire winding frame 2-1. The plurality of rope threading grooves 2-4 are arranged in a circular array with the center of the wire winding frame 2-1 as the center, which can facilitate workers to bundle the completed wire coils with ropes for overall transportation.
[0039] The present invention also provides a wire-receiving method, wherein the wire-receiving device is used for wire-receiving, the wire-discharging device 1-3 rotates to discharge the wire at a rotation speed N and a fixed eccentric angle; the wire-receiving frame 2-1 rotates around its center in a direction opposite to the wire-discharging device 1-3, and the rotation speed n is less than the rotation speed N; the rotation center line of the wire-discharging device 1-3 is not colinear with the rotation center line of the wire-receiving frame 2-1. Each coil of the bundled wire roll obtained by the wire-receiving method has the same size.
[0040] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
