Description

Technical Field

[0001] This utility model belongs to the field of wire drawing machine technology, and specifically relates to a wire drawing drum for a wire drawing machine. Background Technology

[0002] Wire drawing spools are an important piece of equipment in the field of metal wire processing. They are mainly used in the drawing process of metal wires. The drawing process involves stretching the metal wire through a series of dies with reduced dimensions, thereby reducing its diameter while increasing its length and strength. In the wire drawing machine, the wire drawing spool plays the role of storing and conveying the wire. During the conveying process, a large amount of heat is generated, which requires cooling and heat dissipation of the spool.

[0003] For example, in Chinese utility model patent CN222001296U, entitled "A Drawing Drum for a Wire Drawing Machine," the specific components include a drum body with a limiting connecting cylinder at the bottom. The drum body has an annular cooling chamber inside and a cooling mechanism inside. The cooling mechanism includes a liquid storage tank containing coolant, a water pump on one side of the lower surface of the tank, an inlet pipe corresponding to the annular cooling chamber at the pump's output end, a counterweight at the other end of the lower surface of the tank, a drain pipe corresponding to the annular cooling chamber at the top of the tank, and a fan inside the liquid storage tank. Although the above-mentioned prior art achieves rapid and sufficient cooling of the drum body through the cooperation of multiple structures, the drum rotates during use, causing the heated parts to be in different locations. Therefore, in order to allow the heat dissipation range to move with the drum's rotation, a drawing drum for a wire drawing machine is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a wire drawing machine drawing drum with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A wire drawing machine's drawing spool includes a spool body. The outer surface of the spool body has several annular drawing grooves, and the inner side of the annular drawing grooves has several heat dissipation holes penetrating the spool body. A rotating shaft is rotatably arranged at the inner center of the spool body. Several heat dissipation blades are arranged between the rotating shaft and the spool body. A planetary shaft is fixedly arranged at the center of the several heat dissipation blades. A limit assembly is arranged between the planetary shaft and the rotating shaft. Planetary assemblies connected to the two ends of the rotating shaft are arranged at both ends of the planetary shaft.

[0007] As a further optimization of this utility model, the limiting component includes a first limiting bearing fixedly sleeved on the outside of the rotating shaft, a connecting rod fixedly disposed on the outside of the first limiting bearing, and a second limiting bearing fixedly sleeved on the outside of the planetary shaft at the other end of the connecting rod.

[0008] As a further optimization of this utility model, the planetary assembly includes a central gear fixedly sleeved on both ends of the rotating shaft, a gear ring fixedly disposed on the inner side of both ends of the drum body, and planetary gears that mesh with the central gear and the gear rings simultaneously fixedly disposed on both ends of the planetary shaft.

[0009] As a further optimization of this utility model, mounting plates are fixedly provided on both ends of the drum body, and a fixing plate that is rotatably sleeved on the outside of the rotating shaft is fixedly provided on one side of each of the two mounting plates.

[0010] As a further optimization of this utility model, one end of the rotating shaft rotates through the fixing plate, and one end of the two fixing plates is connected to the mounting plate by screws.

[0011] As a further optimization of this utility model, a number of limiting plates located between two adjacent annular wire drawing grooves are fixedly provided on the outer side of the drum body, and an installation cylinder is fixedly provided on one side of one of the fixed plates.

[0012] The beneficial effects of this utility model are as follows: In this utility model, by driving the rotating shaft to rotate, the central gear at one end of the rotating shaft will rotate, causing the planetary gear to revolve and rotate on its own axis inside the gear ring. This will drive the planetary shaft on one side of the planetary gear to revolve and rotate on its own axis inside the drum body, which in turn will drive the heat dissipation blades on the planetary shaft to revolve and rotate on their own axis inside the drum body. The rotation of the heat dissipation blades can quickly dissipate the heat inside the drum body. Furthermore, since the heat dissipation blades can also revolve inside the drum body, the heat dissipation range can move with the rotation of the drum, allowing the heat dissipation to move according to the heated position, thereby improving the heat dissipation effect.

Detailed Implementation

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a wire drawing machine's drawing drum includes a drum body 1. The outer surface of the drum body 1 has several annular drawing grooves 2, each with a semi-circular cross-section. Different diameters can be selected for the annular drawing grooves 2. Several limiting plates 13 are fixedly installed on the outer side of the drum body 1, located between adjacent annular drawing grooves 2. These limiting plates 13 are all circular rings, preventing the wire from detaching from the annular drawing grooves 2 during transport. Several heat dissipation holes 12 penetrating the drum body 1 are provided on the inner side of the annular drawing grooves 2, allowing heat generated by the wire on the outer side of the drum body 1 to be directed to the interior of the drum body 1 for heat dissipation. Mounting plates 3 are fixedly installed on both ends of the drum body 1. Fixing plates 4 are fixedly installed on one side of each mounting plate 3 using screws. A mounting cylinder 14 is fixedly installed on one side of one of the fixing plates 4. The mounting cylinder 14 can be connected to the output end of a motor (not shown in the figure), and the motor drives the mounting cylinder 14. Rotation causes the fixed plate 4 to rotate, which in turn causes the mounting plate 3 on one side of the fixed plate 4 and the drum body 1 to rotate. This, in turn, causes the multiple annular wire drawing grooves 2 on the outer side of the drum body 1 to rotate, thus conveying the wire. A rotating shaft 5 is rotatably arranged between the two fixed plates 4. One end of the rotating shaft 5 rotates through the fixed plate 4 and is connected to the motor (not shown in the figure). The other end of the rotating shaft 5 rotates on one side of the fixed plate 4. Several heat dissipation blades 10 are arranged between the rotating shaft 5 and the drum body 1. A planetary shaft 8 is fixedly arranged at the center of the heat dissipation blades 10. A limit assembly 7 is arranged between the planetary shaft 8 and the rotating shaft 5. The limit assembly 7 includes a first limit bearing 701 fixedly sleeved on the outer side of the rotating shaft 5. A connecting rod 702 is fixedly arranged on the outer side of the first limit bearing 701. A second limit bearing 703 is fixedly sleeved on the outer side of the planetary shaft 8 at the other end of the connecting rod 702. In use, the second limit bearing 703, the connecting rod 702 and the first limit bearing 701 can make the planetary shaft 8 stably positioned on the outer side of the rotating shaft 5.

[0023] like Figure 1 , Figure 2 , Figure 5 As shown, a central gear 6 is fixedly sleeved at both ends of the rotating shaft 5, and a gear ring 11 is fixedly installed on the inner side of both ends of the drum body 1. Planetary gears 9, which mesh with both the central gear 6 and the gear ring 11, are fixedly installed at both ends of the planetary shaft 8. In use, the rotating shaft 5 is driven to rotate by the motor, which in turn drives the central gear 6 on the outside of the rotating shaft 5 to rotate. This causes the planetary gear 9 to revolve around the central gear 6 while rotating on its own axis during the meshing process with the gear ring 11. This causes the planetary shaft 8 on one side of the planetary gear 9 to rotate, so that the multiple heat dissipation blades 10 on the outside of the planetary shaft 8 revolve around the drum body 1 while rotating on their own axis. This allows the heat dissipation range to move with the rotation of the drum body 1, thereby improving the heat dissipation effect.

[0024] It should be noted that, in use, the wire drawing drum of this wire drawing machine can be connected to the output end of the motor via the mounting cylinder 14. The motor drives the mounting cylinder 14 to rotate, which in turn drives the fixed plate 4 to rotate. This causes the mounting plate 3 on one side of the fixed plate 4 and the drum body 1 to rotate, which in turn causes the multiple annular wire drawing grooves 2 on the outer side of the drum body 1 to rotate, thus conveying the wire. At the same time, one end of the rotating shaft 5 rotates through one end of the fixed plate 4 and connects to the motor (not shown in the figure). The motor then drives the rotating shaft 5 to rotate, which in turn drives the central gear 6 on the outer side of the rotating shaft 5 to rotate. This causes the planetary gear 9 to revolve around the central gear 6 while also rotating on its own axis during the meshing process with the gear ring 11. This causes the planetary shaft 8 on one side of the planetary gear 9 to rotate, causing the multiple heat dissipation blades 10 on the outer side of the planetary shaft 8 to revolve around the drum body 1 while rotating on their own axis.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
