DETAILED DESCRIPTION

[0020] Reference Figure 1-Figure 10 A heat drawing cooling device for alloy wires comprises a hollow outer shell 1, wherein the outer shell 1 is arranged at the outlet end of the wire drawing die, and further, the outer shell is detachably mounted on the side wall of the wire drawing machine by bolts arranged on the outer wall.

[0021] Reference Figure 1-Figure 8 In this embodiment, the outer shell 1 is hollow, and the inner diameter of its inner wall is the same, and a cooling seat 3 is fixed at one end thereof, wherein the length of the cooling seat 3 is less than the length of the outer shell 1. In addition, the cooling seat 3 is hollow, and in some embodiments, the inner cavity of the cooling seat 3 is a truncated cone cavity structure. Specifically, the inner diameter of the inner cavity of the end of the cooling seat 3 away from the wire drawing die is larger than the inner diameter of the inner cavity of the other end. Based on the truncated cone structure, the coolant is helped to gather to the bottom of the inner cavity of the cooling seat 3 under the action of its own gravity.

[0022] The coolant is liquid such as water or oil.

[0023] A first cooling cavity 300 is arranged in the cooling seat 3, and the first cooling cavity 300 is arranged in a ring shape in the cooling seat 3, wherein the outer diameter of the wire body to be cooled is smaller than the minimum inner diameter of the inner cavity of the cooling seat 3, thereby ensuring that the coolant sprayed from the first cooling cavity 300 acts on the outer wall of the wire body to be cooled.

[0024] In some embodiments, the structure of the first cooling cavity 300 acting on the wire body to be cooled is a cooling port 301. Specifically, the cooling port 301 is arranged on the inner wall of the cooling seat 3 and is connected to the first cooling cavity 300. In addition, the cooling ports 301 are multiple and equidistantly arranged in an annular shape on the inner wall of the cooling seat 3. After the coolant in the first cooling cavity 300 is sprayed out from the cooling port 301, it adheres to the outer wall of the wire body to be cooled, thereby realizing heat exchange between the cooling liquid and the wire body to be cooled.

[0025] Based on the setting of the cooling seat 3, the structure of the coolant recovery system flowing out from the inner wall of the cooling seat 3 is set as follows: a guide groove 302 is provided at the bottom of the cooling seat 3, wherein the guide groove 302 is arranged in an arc shape at the bottom of the cooling seat 3, and preferably, the center angle of the guide groove 302 is 45°. Further, a water storage tank 5 is provided on the outer wall of the outer shell 1 for collecting the coolant flowing out of the guide groove 302. Among them, the structure that guides the coolant from the guide groove 302 to the water storage tank 5 is a flow channel 100 arranged in the outer shell 1, wherein the flow channel 100 is arranged in an arc shape, and the center angle of the flow channel 100 is smaller than the center angle of the flow channel 302; at the same time, the inlet of the flow channel 100 is located in the guide groove 302, which helps to guide the coolant in the guide groove 302 to the flow channel 100. In addition, a supply pipe and a liquid outlet pipe are provided on the outer wall of the water storage tank 5, which are used to replenish the coolant in the water storage tank 5 and to guide the coolant.

[0026] Reference Figure 3-Figure 8 A cooling chuck 2 slides horizontally inside the outer shell 1 for further cooling the wire body to be cooled. When the cooling chuck 2 is clamped on the outer wall of the wire body to be cooled, it moves synchronously with the wire body to be cooled. Furthermore, the cooling liquid flowing in the cooling chuck 2 cools the wire body to be cooled clamped therein.

[0027] First, the cooling chuck 2 includes a driving housing seat 200 and a cooling cavity seat 201, wherein the driving housing seat 200 is hollow, and the cooling cavity seat 201 is two, which are respectively composed of an upper clamp seat 2010 and a lower clamp seat 2011. When the upper clamp seat 2010 and the lower clamp seat 2011 are attached, the alloy wire to be cooled is clamped. The upper clamp seat 2010 and the lower clamp seat 2011 linearly slide in the hollow cavity in the driving housing seat 200.

[0028] It should be noted that the drive housing seat 200 slides horizontally in the outer shell 1 through a driving member. In some embodiments, the driving member may be a pull wire or a screw. When the driving member is a pull wire, the horizontal linear movement of the drive housing seat 200 in the outer shell 1 is achieved by winding or unwinding the pull wire. In this embodiment, the drive housing seat 200 also needs to be connected to a reset tension spring to ensure the reset of the drive housing seat 200 after being pulled. When the driving member is a screw, the drive housing seat 200 and the screw are threadedly connected, and the horizontal linear movement of the drive housing seat 200 in the outer shell 1 is achieved by rotating the screw. However, the driving member is not limited to the above two structures, and any structure that can achieve horizontal linear movement of the drive housing seat 200 is acceptable.

[0029] In addition, to ensure stable sliding of the drive housing seat 200 and stable linear sliding between the drive housing seat 200 and the outer shell 1, the drive housing seat 200 can be constrained by a slide seat and a slide rail.

[0030] Reference Figure 3-Figure 8The cooling chamber seat 201 is provided with a second cooling chamber 202 and a third cooling chamber 203. Further, the second cooling chamber 202 is located between the first cooling chamber 300 and the third cooling chamber 203. In addition, the second cooling chamber 202 and the third cooling chamber 203 are closed spaces in the cooling chamber seat 201.

[0031] In addition, a water storage tank 5 is also provided on the outer wall of the outer shell 1. Based on the arrangement of the first cooling chamber 300, the second cooling chamber 202 and the third cooling chamber 203, the implementation method for temperature control in this embodiment is as follows: The inlet end of the first cooling chamber 300 is connected to the outlet end of the second cooling chamber 202, and the connection structure can be realized through a connecting pipe 14; The inlet end of the second cooling chamber 202 is connected to the outlet end of the third cooling chamber 203, and the connection structure can be realized through the connecting pipe 3 8; The inlet end of the water storage tank 5 is connected to the outlet end of the first cooling chamber 300, and the connection structure is realized by the flow channel 100, which is easy to dissipate heat and reduce the temperature of the coolant; the outlet end of the water storage tank 5 is connected to the inlet end of the third cooling chamber 203, and the connection structure can be realized by the connecting pipe 2 7; The connecting pipe 1 4, the connecting pipe 2 7 and the connecting pipe 3 8 are all hose structures; it should be added that the flow of the coolant in the connecting pipe 1 4, the connecting pipe 2 7 and the connecting pipe 3 8 is provided with kinetic energy by the water pump body 1 6 arranged in the water storage tank 5, and specifically, one end of the connecting pipe 2 7 is fixed to the output end of the water pump body 1 6; In summary, in this embodiment, the cooling of the wire body after hot drawing is divided into three stages, the first stage is the open cooling stage, the second stage and the third stage are the wrapped cooling stage, and the specific implementation methods of the three stages are as follows: The first stage: the coolant in the first cooling cavity 300 is sprayed out from the cooling port 301 and sprayed toward the outer wall of the wire body located in the middle of the cooling seat 3, and the coolant attached to the outer wall of the wire body realizes heat exchange with the wire body; The second stage: the upper clamping seat 2010 and the lower clamping seat 2011 of the cooling chamber seat 201 clamp the wire body, so that the cooling chamber seat 201 and the wire body move synchronously and at the same speed, and the coolant in the second cooling chamber 202 flows, and the heat exchange between the coolant and the wire body is realized through the transfer of the cooling chamber seat 201; The third stage: This stage is the same as the second stage. After the cooling cavity seat 201 clamps the wire body, the coolant in the third cooling cavity 203 flows and is transferred through the cooling cavity seat 201 to achieve heat exchange with the wire body. In the above three stages, the processes of realizing heat exchange are carried out separately, and the difference is that the coolant in the first cooling chamber 300 is the coolant cooled in the second cooling chamber 202, and the coolant in the second cooling chamber 202 is the coolant cooled in the third cooling chamber 203, wherein the first cooling chamber 300, the second cooling chamber 202 and the third cooling chamber 203 are cooled down in sequence along the moving direction of the line body; Furthermore, the temperature of the coolant in the first cooling chamber 300 is the temperature of the coolant after the second cooling chamber 202 absorbs heat, which makes the difference between the temperature of the coolant and the temperature of the wire just out of the hot drawing die smaller; further, the temperature of the coolant in the second cooling chamber 202 in the second stage is the temperature of the coolant after the third cooling chamber 203 absorbs heat, which makes the difference between the temperature of the coolant and the temperature of the wire just out of the first stage smaller; finally, the temperature of the coolant in the third cooling chamber 203 in the third stage is the temperature of the coolant after the first cooling chamber 300 absorbs heat and cools down, which makes the difference between the temperature of the coolant and the temperature of the wire just out of the second stage smaller. It can be seen that the temperature of the coolant decreases from the first stage to the third stage in sequence, and the temperature of the coolant in the first stage and the second stage does not require an external heating structure to achieve temperature regulation, and relies entirely on the coolant that absorbs heat at the back of the wire to replenish the coolant at the front end, which achieves an energy-saving effect.

[0032] It should be added that the coolant flowing out from the first stage flows to the water storage tank 5 through the flow channel 100. During this process, the flow channel 100 is set along the outer shell 1. When the coolant flows in the flow channel 100, the coolant dissipates heat with the outside through the outer shell 1 during the flow process, resulting in the temperature of the coolant entering the water storage tank 5 after heat dissipation being lower than the temperature of the coolant in the second stage.

[0033] Reference Figure 3-Figure 8 This embodiment also discloses a cooling clamping tube 2 clamping structure to ensure the progress of the second and third stages, wherein two U-shaped slide rails 9 are arranged in the outer shell 1, and the outer wall of the cooling chamber seat 201 is fixedly connected with a T-shaped slide seat 204. The matching relationship between the U-shaped slide rail 9 and the T-shaped slide seat 204 is as follows: First, the T-shaped slide 204 is fixed to the outer wall of the cooling chamber seat 201, and the vertical end of the T-shaped slide 204 penetrates the drive housing seat 200 and extends outward, and a spring is sleeved on the outer wall of the vertical end of the T-shaped slide 204, and the two ends of the spring are connected to the inner wall of the drive housing seat 200 and the outer wall of the cooling chamber seat 201. It should be added that: in the initial state of the spring, the upper clamp seat 2010 and the lower clamp seat 2011 are separated from each other.

[0034] Secondly, there are two U-shaped slide rails 9, which are symmetrically arranged in the outer shell 1 and correspond to the upper clamping seat 2010 and the lower clamping seat 2011 respectively. Furthermore, the U-shaped slide rail 9 is provided with a sliding opening 900 corresponding to the vertical end of the T-shaped slide 204, and the U-shaped slide rail 9 is also provided with four through openings 901 corresponding to the horizontal end of the T-shaped slide 204.

[0035] In this embodiment, during the second and third stage clamping and cooling processes, Figure 7 , the T-shaped slide 204 moves horizontally along the opposite end of the U-shaped slide 9. At this time, under the resistance of the U-shaped slide 9, the spring is in a compressed state, and the upper clamping seat 2010 and the lower clamping seat 2011 maintain a clamping state. When the cooling chuck 2 moves to the end of the U-shaped slide 9 away from the cooling seat 3, under the action of the spring, the T-shaped slide 204 passes through the corresponding through hole 901 and moves outward until the T-shaped slide 204 is located in the U-shaped slide 9, and then under the action of the driving member, the cooling chuck 2 moves toward the cooling seat 3. Figure 8 During this process, the upper clamping seat 2010 and the lower clamping seat 2011 are in a separated state, preparing for the next clamping of the wire body. When the cooling chuck 2 moves to the end close to the cooling seat 3, refer to Figure 6 The T-shaped slide 204 is subjected to the force of the extruder, causing the upper clamping seat 2010 and the lower clamping seat 2011 to approach each other, thereby clamping the wire body. During this process, the horizontal end of the T-shaped slide 204 passes through the through hole 901 in the U-shaped slide rail 9 and moves outward.

[0036] In some embodiments, based on the setting of the through-opening 901, in order to prevent the T-shaped slide 204 from being misplaced and entering into a non-designated through-opening 901 in advance during the movement of the cooling chuck 2 with the wire body, the length of the horizontal end of the T-shaped slide 204 away from the cooling seat 3 is smaller than the length of the horizontal end of the other T-shaped slide 204. At the same time, the width of the horizontal end of the T-shaped slide 204 away from the cooling seat 3 is larger than the width of the horizontal end of the other T-shaped slide 204. During use, the four through-holes 901 are divided into two groups, and the shapes of the two groups of through-holes 901 are the same as the external shapes of the horizontal ends of the two T-shaped slides 204. In this way, based on the matching of the shape alignment features, it is ensured that the T-shaped slide 204 will not enter into the non-specified through-holes 901. Furthermore, it is ensured that when the cooling chuck 2 moves with the wire body or when the cooling chuck 2 returns to the initial state, the upper clamp seat 2010 and the lower clamp seat 2011 maintain a clamped or separated state. Only when the cooling chuck 2 is located close to one end of the cooling seat 3 or away from one end of the cooling seat 3, the clamped or separated state of the upper clamp seat 2010 and the lower clamp seat 2011 can be adjusted.

[0037] Reference Figure 3-Figure 8In some embodiments, the extrusion member is a connecting seat 10 and two through-mouth abutment portions 101 disposed on the connecting seat 10, wherein the two through-mouth abutment portions 101 are directly opposite to the two through-mouths 901 close to the cooling seat 3. Then, when the cooling chuck 2 moves to the end portion close to the cooling seat 3, the two connecting seats 10 move relative to each other, so that the through-mouth abutment portions 101 abut against the T-shaped slide 204, causing the T-shaped slide 204 to pass through the through-mouth 901 and move outward from the U-shaped slide rail 9 until the side wall of the through-mouth abutment portion 101 is flush with the side walls of the opposite ends of the two U-shaped slide rails 9, thereby completing the clamping of the wire body after the relative movement of the upper clamp seat 2010 and the lower clamp seat 2011, and then under the action of the driving member, the wire body moves in the same direction and at the same speed as the wire body. It should be supplemented that the driving force for the linear movement of the connecting seat 10 can be a screw driven by a cylinder and a servo motor in the prior art, but is not limited to the above two methods, and any electronic driving member that can drive the connecting seat 10 to move linearly can be used.

[0038] It should be added that the distance that the cooling chuck 2 moves synchronously with the wire body at the same speed is between half of the length of the cooling chuck 2 and the length of the cooling chuck 2. In this way, after the cooling chuck 2 completes a round of second and third stage cooling treatments after moving with the wire body, the next clamping position still has the same area as the last clamping. In this way, the cooling chuck 2 covers the entire flowing wire body when clamping, and there will be no dead corners for wire body cooling.

[0039] In addition, this embodiment also discloses a control structure for adjusting the temperature of the coolant entering the first cooling chamber 300 and the second cooling chamber 202. The control principle is to adjust the distance of the coolant flow in the second cooling chamber 202 and the third cooling chamber 203. Figure 3-Figure 8 , the structure is set up as follows: When adjusting the temperature of the coolant entering the first cooling chamber 300, an outlet plug seat 11 is horizontally slidably connected in the second cooling chamber 202, and the outlet end of the second cooling chamber 202 is a water outlet arranged on the outlet plug seat 11, and the water outlet is connected to one end of the connecting pipe 4. By moving the position of the outlet plug seat 11, the actual flow distance of the coolant in the second cooling chamber 202 is changed, thereby causing the heat exchange flow rate and time of the coolant in the second cooling chamber 202 through the cooling chamber seat 201 and the line body to change, thereby changing the temperature of the coolant flowing out of the second cooling chamber 202, and then changing the temperature of the coolant entering the first cooling chamber 300; When adjusting the temperature of the coolant entering the second cooling chamber 202, an inlet plug seat 12 is horizontally slidably connected to the third cooling chamber 203. The inlet end of the third cooling chamber 203 is a water inlet arranged on the inlet plug seat 12. The water inlet is connected to one end of the connecting pipe 27. By moving the position of the inlet plug seat 12, the actual flow distance of the coolant in the third cooling chamber 203 is changed, thereby causing the heat exchange flow rate and time of the coolant in the third cooling chamber 203 through the cooling chamber seat 201 and the line body to change, thereby changing the temperature of the coolant flowing out of the third cooling chamber 203, and then changing the temperature of the coolant entering the second cooling chamber 202.

[0040] It should be supplemented that the horizontal movement of the outlet plug seat 11 and the inlet plug seat 12 can be achieved by linear drive electronic components such as cylinders.

[0041] It can be seen that by changing the actual coolant flow distance of the second cooling chamber 202 and the third cooling chamber 203, the coolant temperature entering the first cooling chamber 300 and the second cooling chamber 202 can be adjusted, thereby controlling the temperature difference between the coolant and the wire body, which helps to slowly cool down the wire body in stages.

[0042] In this embodiment, refer to Fig. 9 In order to facilitate the independent control of the water volume and flow rate of the first cooling chamber 300, the second cooling chamber 202 and the third cooling chamber 203, instead of using the unified control method of the water pump body 16, the connecting pipe 14 and the connecting pipe 38 are both connected with a water storage tank 15, and a water pump body 2 13 is arranged in the water storage tank 15. Specifically, the water storage tank 15 on the connecting pipe 14 and the water pump body 2 13 therein regulate the flow rate and flow rate of the coolant entering the first cooling chamber 300; the water storage tank 15 on the connecting pipe 38 and the water pump body 2 13 therein regulate the flow rate and flow rate of the coolant entering the second cooling chamber 202; the water storage tank 5 and the water pump body 16 therein regulate the flow rate and flow rate of the coolant entering the third cooling chamber 203.

[0043] In some embodiments, reference Fig.10In order to further control the cooling effect, the actual flow space of the coolant in each cooling cavity can be adjusted. The structure is set as follows: the first cooling cavity 300, the second cooling cavity 202 and the third cooling cavity 203 are all connected with a radially movable rubber sealing seat 14. When the rubber sealing seat 14 moves into the first cooling cavity 300, the second cooling cavity 202 and the third cooling cavity 203, the actual flow space of the coolant in the first cooling cavity 300, the second cooling cavity 202 and the third cooling cavity 203 becomes smaller, so that the cooling effect becomes worse. Correspondingly, the temperature of the coolant flowing out of the second cooling cavity 202 and the third cooling cavity 203 can also be adjusted; conversely, when the rubber sealing seat 14 moves out of the first cooling cavity 300, the second cooling cavity 202 and the third cooling cavity 203, the actual flow space of the coolant in the first cooling cavity 300, the second cooling cavity 202 and the third cooling cavity 203 becomes larger, so that the cooling effect becomes better.

[0044] It should be added that the movement of the rubber sealing seat 14 can be achieved by linear drive electronic components such as cylinders.

[0045] Finally, in this embodiment, in order to accurately control the temperature and flow rate of the coolant flowing to the first cooling chamber 300, the second cooling chamber 202 and the third cooling chamber 203, solenoid valves, temperature sensors and flow sensors are provided in the connecting pipe 1 4, the connecting pipe 2 7, the connecting pipe 3 8 and the flow channel 100. The setting of the solenoid valve controls the flow rate and flow rate of the coolant. The temperature sensor senses the temperature of the coolant entering each cooling chamber to determine whether it meets the set temperature. If it does not meet the set temperature, the coolant outflow temperature of the second cooling chamber 202 and the third cooling chamber 203 is adjusted. The flow sensor senses the flow rate of the coolant entering each cooling chamber to determine whether it meets the set flow rate.
