Description

Technical Field

[0001] This utility model relates to the field of wire take-up mechanism technology, and in particular to a wire take-up mechanism for a large copper wire drawing machine. Background Technology

[0002] The utility model with publication number CN221086772U relates to the field of wire take-up technology, specifically a take-up mechanism for a large copper wire drawing machine. It includes a base plate with two mounting plates symmetrically fixed at one end of the upper side of the base plate. This utility model uses a forward / reverse motor to drive a lead screw to rotate, which in turn drives a moving block to move horizontally through threaded engagement. This, in turn, causes the L-shaped plate and the take-up roller to move synchronously, preventing the copper wire from being unevenly spread on the outer wall of the take-up roller, thus preventing a large accumulation of wire in the middle of the take-up roller, reducing its space utilization and wasting space resources. By providing two straightening rollers, the copper wire can be flattened before take-up, improving the tightness of the take-up. Three limiting holes allow for the installation of take-up rollers of different sizes, enabling replacement as needed and improving the applicability of the device. Two limiting blocks symmetrically fixed on the outer side of the take-up roller effectively prevent the copper wire from falling off during take-up.

[0003] After searching, it was found that the existing technology has certain defects. The existing technology uses a fixed straightening wheel, which cannot adapt to copper wires of different diameters. In addition, the copper wire that comes out of the drawing die is at a high temperature. If it cannot be cooled in time, it will affect the wire performance and be detrimental to subsequent winding. Therefore, a winding mechanism for a large copper wire drawing machine is needed to meet people's needs. Summary of the Invention

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A take-up mechanism for a large copper wire drawing machine includes a base 1, a first bracket 2 on the base 1, and a pressure rod 4 movably connected to the first bracket 2 by bolts 3. The bottom end of the pressure rod 4 and the top end of the first bracket 2 are provided with several corresponding mold slots 5. The same drawing die 6 is installed in every two corresponding mold slots 5. Loosening the bolts 3 can rotate the pressure rod 4, and tightening the bolts 3 can fix the pressure rod 4. When the pressure rod 4 is pressed down, each pair of corresponding mold slots 5 can fix one drawing die 6 together.

[0017] A cooling tank 7 is provided on the base 1, and the cooling tank 7 is filled with coolant. The cooling tank 7 is located below the first support 2. A water pump 8 is provided in the cooling tank 7, and a shower pipe 9 is connected to the water pump 8. The water outlet of the shower pipe 9 points to the drawing die 6. A wire guide mechanism 10 and a support plate 11 are also provided on the base 1. The function of the wire guide mechanism 10 is to guide the copper wire to move left and right in an orderly manner. A take-up motor 12 is provided on one side of the support plate 11. An air expansion shaft 13 is connected to the output shaft of the take-up motor 12. A take-up roller 14 is movably installed on the air expansion shaft 13. By inflating and deflating the air expansion shaft 13, the take-up roller 14 can be easily installed or removed.

[0018] Specifically, in this embodiment, there are two sets of rinsing pipes 9. The two sets of rinsing pipes 9 are connected to the water outlet of the water pump 8 through a tee and are respectively arranged at the inlet and outlet of the drawing die 6. This allows for bidirectional cooling of the copper wire, that is, cooling is performed simultaneously before the copper wire enters the die hole and after it is drawn out of the die hole. The cooling effect is more uniform and more thorough. At the same time, the copper shavings at the inlet end are rinsed to prevent blockage of the die hole.

[0019] Specifically, in this embodiment, a filter tank 15 is movably connected to the top of the cooling tank 7. The top of the filter tank 15 extends outwards and is arranged on the top of the cooling tank 7. The filter tank 15 can collect impurities such as scale and metal shavings that fall off the surface of the copper wire, keep the coolant clean, extend its service life, and facilitate cleaning.

[0020] Specifically, in this embodiment, the wire guide mechanism 10 consists of a support base, a drive motor, a reciprocating lead screw, a reciprocating slide block, and a wire guide ring (not fully shown in the figure). It can guide the copper wire to be evenly distributed back and forth on the take-up roller 14, avoiding the wire from piling up in one place.

[0021] Specifically, in this embodiment, a second support 16 is provided on the base 1. The second support 16 is arranged below the take-up roller 14. Several springs 17 are provided on the top of the second support 16. The same roller frame 18 is provided on the top of the several springs 17. A pressure roller 19 is rotatably connected inside the roller frame 18. The pressure roller 19 is arranged parallel to the bottom of the inner roller of the take-up roller 14. The elastic force of the springs 17 makes the pressure roller 19 always close to the wire coil on the take-up roller 14. As the diameter of the wire coil increases, it automatically presses down, thereby ensuring the tightness of the winding and is suitable for copper wires of different diameters.

[0022] Specifically, in this embodiment, a number of guide rods 20 are connected to the bottom end of the roller frame 18. The guide rods 20 are slidably connected to the top end of the second bracket 16. The guide rods 20 play a guiding and stabilizing role, ensuring that the roller frame 18 moves smoothly in the vertical direction and preventing it from tilting.

[0023] Working principle: The copper wire first passes through the drawing die 6 for drawing and diameter reduction. At the same time, the water pump 8 is started, and the coolant is continuously sprayed onto both ends of the drawing die 6 through two sets of spray pipes 9 to cool the high-temperature copper wire. After cooling, the copper wire is guided by the wire guide mechanism 10 and is evenly wound onto the take-up roller 14 driven by the take-up motor 12. During the take-up process, the pressure roller 19 is always pressed tightly against the wire roll under the action of the spring 17 to ensure the tightness of the take-up. As the take-up diameter increases, the roller frame 18 will compress the spring 17 and move downward along the guide rod 20 to always maintain appropriate pressure.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
