Description

Technical Field

[0001] The present application relates to the technical field of wire drawing machines, and in particular to a wire drawing machine reel with a heat dissipation device. Background Art

[0002] Wire drawing machine is one of the important equipment in the metal products industry. The temperature of the steel wire rises during the drawing process, which will cause strain aging hardening of the steel wire. In order to improve the comprehensive mechanical properties of the steel wire, effective cooling measures must be taken on the reel.

[0003] The working surface of traditional wire drawing machines is mostly located at the bottom of the wire drawing drum, so the temperature of the space below the wire drawing drum is relatively high. The traditional water cooling system does not effectively cool the working surface below the inner wall of the wire drawing drum, resulting in the failure to achieve the theoretical cooling effect. At the same time, since the wire drawing machine is drawing wire rods of different diameters, the running speed of the wire drawing machine is also very different, so the temperature generated on the working surface is also very different, which greatly reduces the production quality of the wire drawing machine. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the present application provides a wire drawing machine reel with a heat dissipation device.

[0005] The present application provides a wire drawing machine reel with a heat dissipation device adopts the following technical solution:

[0006] A wire drawing machine drum with a heat dissipation device comprises a drum, wherein an opening is provided at the bottom of the drum, a motor for driving the drum to rotate is installed at the bottom of the drum, the outer side of the bottom of the drum is rotatably connected to a wire drawing table, and an air cooling mechanism sleeved on the drum is installed on the surface of the wire drawing table, a cooling ring is installed in the cavity of the drum, and a gap is provided between the cooling ring and the inner wall of the drum; a cooling ring, wherein a plurality of grooves are distributed circumferentially on one side of the cooling ring close to the inner wall of the drum, and oblique ribs for separating the grooves are provided in the grooves, the oblique ribs divide the grooves into two identical groove bodies, wherein a channel connecting the two groove bodies is opened on the oblique ribs, and a water inlet is also provided in the groove body; an air cooling mechanism, wherein the air cooling mechanism is sleeved on the drum, and comprises an air cooling cavity surrounding the outer wall of the drum, and an air inlet and an air outlet located at the bottom and outside of the air cooling cavity.

[0007] By adopting the above technical solution, the reel adopts a bottom opening design and is driven by a motor from the bottom to rotate on the wire drawing table, wherein the air cooling mechanism mounted on the reel introduces air through the air inlet, and is discharged through the air outlet after passing through the air cooling cavity surrounding the bottom of the outer wall of the reel. The air absorbs the heat at the bottom of the reel and is discharged through the exhaust fan at the air outlet. At the same time, a gap is provided between the cooling ring arranged inside the reel and the inner wall of the reel, and the cooling ring introduces cooling water through the water inlet. After the cooling water enters the groove, it can be stored and flows out through the gap between the cooling ring and the inside of the reel, and the reel is cooled from the inner wall of the reel, wherein the cooling ring is divided into a plurality of grooves, and the groove is divided into two identical groove bodies by oblique ribs, and a channel connecting the two groove bodies is provided in the oblique ribs, so that the introduced cooling water can be evenly distributed on the inner wall of the reel, and the inner wall of the reel can be cooled more evenly. In the present application, water cooling is performed on the inner wall of the drum through a cooling ring, and the water-cooled water will flow downward under the action of gravity. Combined with the air cooling mechanism arranged at the bottom of the outer side of the drum, the lower space of the wire drawing machine drum can be effectively cooled.

[0008] Preferably, the grooves are isolated by longitudinally distributed isolation rods, and the oblique ribs in the grooves divide the grooves into two upper and lower groove bodies.

[0009] Preferably, the water inlet is located in the upper tank body, and an overflow port communicating with the outside is provided at the top of the upper tank body.

[0010] By adopting the above technical solution, the isolation rods are distributed longitudinally, the grooves in the cooling ring are arranged in a circular array on the cooling ring, and the oblique ribs divide the grooves into two upper and lower groove bodies in the grooves, and the grooves for storing coolant are divided into two separate upper and lower groove bodies, and the water inlet introduces cooling water from the upper groove body. The introduced cooling water can store a part of the cooling water in the upper groove body under the action of the oblique ribs and then introduce the water into the lower groove body. At the beginning, the cooling water can be evenly distributed in the cooling ring through the separation of the oblique ribs. After the subsequent cooling water volume gradually increases, when the drainage speed between the drum and the cooling ring is less than the water inlet speed, the cooling water can overflow from the overflow port at the top.

[0011] Preferably, a water inlet pipe is connected to the inner side of the water inlet, and an annular water receiving trough is installed at the bottom of the reel and the cooling ring.

[0012] By adopting the above technical solution, the water inlet pipe connected to the inner side of the water inlet is responsible for the introduction of cooling water, and the annular water receiving trough at the bottom is responsible for the collection of cooling water. Both can realize the circulation of cooling water through an external cooling water circulation mechanism.

[0013] Preferably, a flow rate regulator is installed on the water inlet pipe, and a liquid level detector is installed on the overflow port, and the two are electrically connected.

[0014] By adopting the above technical solution, the flow rate regulator set on the water inlet pipe can adjust the water inlet speed of the cooling water, and the liquid level detector installed on the overflow port on the groove can monitor in real time whether the cooling water overflows from the overflow port, so as to judge whether the water inlet and water outlet speeds are balanced. With the long-term use of the wire drawing machine reel, the interval between the reel and the cooling ring may change slightly, resulting in a change in the water outlet speed. Therefore, the flow rate regulator and the liquid level detector are electrically connected to monitor in real time and adjust the cooling water inlet speed in time.

[0015] Preferably, a reinforcing block is installed in the reel, and the reinforcing block is integrally formed with the top of the reel, a through hole fixedly connected to the motor output shaft is provided in the reinforcing block, and a limiting groove is provided on the side of the through hole.

[0016] By adopting the above technical solution, the reinforcement block installed in the reel is integrally formed with the top of the reel, which facilitates the connection between the output shaft of the motor and the through hole on the reinforcement block, and the output shaft can drive the reel to rotate in conjunction with the limiting groove opened on the side.

[0017] Preferably, the reinforcement block is located at the center of the reel, and a support groove with a diameter larger than the through hole is opened at the bottom of the reinforcement block, and a support ring adapted thereto is fixed on the motor output shaft.

[0018] By adopting the above technical solution, the reinforcement block is located at the center of the reel, which can improve the stability of the reel rotation process, and the support groove opened at the bottom of the reinforcement block can cooperate with the support ring on the output shaft, thereby avoiding that the support of the reel falls entirely on the wire drawing table, further improving the stability of the reel rotation.

[0019] Preferably, the air inlet at the bottom of the air cooling mechanism is connected to a blower.

[0020] By adopting the above technical solution, a blower is used at the air inlet of the air cooling mechanism to achieve high-speed air cooling of the reel.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The inner wall of the drum is water-cooled through the cooling ring, and the water-cooled water will flow downward under the action of gravity. Together with the air-cooling mechanism arranged at the bottom of the outer side of the drum, the lower space of the wire drawing machine drum can be effectively cooled;

[0023] 2. The heat from the reel is taken away by the cooling water between the cooling ring and the reel, and an air blower is used to accelerate the heat dissipation. Indirect water cooling and direct air cooling are used to effectively dissipate the heat of the wire drawing machine reel. Different from the traditional structure of the entire drawing line using an integral cooling device, cooling a single reel is more conducive to improving the drawing quality.

The oblique rib 511 divides the groove 51 into two identical groove bodies 512, wherein the oblique rib 511 is provided with a channel 513 for connecting the two groove bodies 512, and the groove body 512 is also provided with a water inlet 514; the air cooling mechanism 4 is mounted on the reel 1, and comprises an air cooling cavity 41 surrounding the outer wall of the reel 1, and an air inlet 42 and an air outlet 43 located at the bottom and outside of the air cooling cavity 41. The reel 1 adopts a bottom opening design and is driven from the bottom by a motor 2 to rotate on the wire drawing table 3, wherein the air cooling mechanism 4 mounted on the reel 1 introduces air through the air inlet 42, passes through the air cooling cavity 41 surrounding the bottom of the outer wall of the reel 1, and is discharged through the air outlet 43, and the air absorbs the heat at the bottom of the reel 1 and is discharged through the exhaust fan of the air outlet 43. At the same time, a gap is provided between the cooling ring 5 provided inside the reel 1 and the inner wall of the reel 1. The cooling ring 5 introduces cooling water through the water inlet 514. After the cooling water enters the groove 51, it can be stored and flows out through the gap between the cooling ring 5 and the inside of the reel 1, and the reel 1 is cooled from the inner wall of the reel 1. The cooling ring 5 is divided into a plurality of grooves 51, and the groove 51 is divided into two identical groove bodies 512 by the oblique rib 511, and a channel 513 connecting the two groove bodies 512 is provided in the oblique rib 511, so that the introduced cooling water can be evenly distributed on the inner wall of the reel 1, and the inner wall of the reel 1 can be cooled more evenly. In the present application, the inner wall of the reel 1 is water-cooled by the cooling ring 5, and the water-cooled water will flow downward under the action of gravity, and cooperate with the air cooling mechanism 4 provided at the bottom of the outer side of the reel 1, so that the lower space of the wire drawing machine reel 1 can be effectively cooled.

[0031] Reference Figure 1 , Figure 2 and Figure 3The grooves 51 are separated by longitudinally distributed isolation rods 52, and the oblique ribs 511 in the grooves 51 divide the grooves 51 into two upper and lower groove bodies 512. The water inlet 514 is located in the upper groove body 512, and the top of the upper groove body 512 is provided with an overflow port 515 connected to the outside. The isolation rods 52 are distributed longitudinally, and the grooves 51 in the cooling ring 5 are arranged in a circular array on the cooling ring 5, and the oblique ribs 511 divide the grooves 51 into two upper and lower groove bodies 512 in the grooves 51, and the grooves 51 for storing coolant are divided into two upper and lower separate groove bodies 512, and the water inlet 514 introduces cooling water from the upper groove body 512.

At the beginning, the cooling water can be evenly distributed in the cooling ring 5 through the separation of the oblique ribs 511. After the amount of cooling water gradually increases, when the drainage speed between the reel 1 and the cooling ring 5 is less than the water inlet speed, the cooling water can overflow from the overflow port 515 at the top.

[0032] Reference Figure 2 and Figure 3 The water inlet 514 is connected to a water inlet pipe 6, and an annular water receiving groove 7 is installed at the bottom of the reel 1 and the cooling ring 5. The water inlet pipe 6 connected to the inside of the water inlet 514 is responsible for the introduction of cooling water, and the annular water receiving groove 7 at the bottom is responsible for the collection of cooling water. The two can realize the circulation of cooling water through an external cooling water circulation mechanism.

[0033] Reference Figure 2 and Figure 3 , a flow rate regulator 61 is installed on the water inlet pipe 6, and a liquid level detector 516 is installed on the overflow port 515, and the two are electrically connected. The flow rate regulator 61 set on the water inlet pipe 6 can adjust the water inlet speed of the cooling water, and the liquid level detector 516 installed on the overflow port 515 on the groove 51 can monitor in real time whether the cooling water overflows from the overflow port 515, so as to judge whether the water inlet and outlet speeds are balanced. With the long-term use of the wire drawing machine reel 1, the interval between the reel 1 and the cooling ring 5 may change slightly, resulting in a change in the water outlet speed. Therefore, the flow rate regulator 61 and the liquid level detector 516 are electrically connected, so that the cooling water inlet speed can be monitored in real time and adjusted in time.

[0034] Reference Figure 2 and Figure 3A reinforcing block 11 is installed in the reel 1, and the reinforcing block 11 is integrally formed with the top of the reel 1. A through hole 111 fixedly connected to the output shaft of the motor 2 is provided in the reinforcing block 11, and a limiting groove 112 is provided on the side of the through hole 111. The reinforcing block 11 installed in the reel 1 is integrally formed with the top of the reel 1, so that the output shaft of the motor 2 is conveniently connected to the through hole 111 on the reinforcing block 11, and the limiting groove 112 provided on the side can realize that the output shaft drives the reel 1 to rotate.

[0035] Reference Figure 2 and Figure 3 The reinforcing block 11 is located at the center of the reel 1, and a support groove 113 with a diameter larger than the through hole 111 is provided at the bottom of the reinforcing block 11, and a matching support ring 21 is fixed on the output shaft of the motor 2. The reinforcing block 11 is located at the center of the reel 1, which can improve the stability of the reel 1 during rotation, and the support groove 113 provided at the bottom of the reinforcing block 11 can cooperate with the support ring 21 on the output shaft, thereby preventing the support of the reel 1 from falling entirely on the wire drawing table 3, further improving the stability of the rotation of the reel 1.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The air inlet 42 at the bottom of the air cooling mechanism 4 is connected to a blower 421. The air inlet 42 of the air cooling mechanism 4 uses the blower 421 to achieve high-speed air cooling of the reel 1.

[0037] Working principle: The bottom of the reel 1 is installed on the wire drawing table 3, and the motor 2 at the bottom of the reel 1 drives the reel 1 to rotate on the wire drawing table 3, wherein the output shaft of the motor 2 drives the reinforcing block 11 fixed on the top of the reel 1 to rotate to realize the rotation of the reel 1, and a support ring 21 is also installed on the output shaft to support the reel 1. The air cooling mechanism 4 works through the blower 421 at the bottom, and introduces air from the air inlet 42. The air flows in the air cooling cavity 41 around the reel 1 to absorb heat from the reel 1, and the air is discharged through the side air outlet 43 to realize air cooling. The cooling ring 5 located on the inner side of the reel 1 introduces cooling water from the water inlet 514 through the water inlet pipe 6. The cooling water enters the upper groove body 512 and then enters the lower groove body 512 through the channel 513 on the oblique rib 511. The coolant in the entire groove 51 can flow out through the gap between the reel 1 and the cooling ring 5. When the outflow speed of the coolant stored in the groove 51 is lower than the inflow speed of the coolant, the coolant will overflow from the overflow port 515 on the top of the cooling ring 5. At this time, the liquid level detector 516 will transmit the signal of detecting the overflow of the coolant to the flow rate regulator 61 on the water inlet pipe 6, and adjust the water inlet speed, thereby realizing the cooling of the inner wall of the reel 1 without causing waste of coolant.
