Description

[0002] Alloy gold wire is a material used in construction and industrial production. The surface of the wire should be smooth and clean, without cracks, burrs, rough drawing channels, folds, and inclusions.

[0003] Hot drawing is a processing method for alloy wires. After heating and passing through a die, the wire size is changed. After hot drawing treatment, the wire needs to be cooled. The existing cooling method mainly adopts water cooling. Specifically, it allows the wire to pass through a water tank, making the water directly contact the wire to take away heat. However, the cooling speed of water cooling is fast, which can quickly cool down the wire. Correspondingly, the sharp temperature change will generate thermal stress, resulting in defects such as cracks on the wire surface. Summary of the Invention

[0017] The U-shaped slide rail is provided with a slide opening corresponding to the vertical end of the T-shaped slide seat, and the U-shaped slide rail is also provided with four through openings corresponding to the horizontal end of the T-shaped slide seat.

[0018] Preferably, a connecting seat is radially slidable in the U-shaped slide rail, and through-opening abutment portions are fixed at both ends of the connecting seat, and the two through-opening abutment portions are directly opposite to the two through-openings close to the cooling seat.

[0019] Preferably, the length of the horizontal end of the T-shaped slide away from one end of the cooling seat is smaller than the length of the horizontal end of the other T-shaped slide, and the width of the horizontal end of the T-shaped slide away from one end of the cooling seat is larger than the width of the horizontal end of the other T-shaped slide.

[0020] Preferably, an outlet plug seat is horizontally slidably connected in the second cooling cavity, and the outlet end of the second cooling cavity is a water outlet arranged on the outlet plug seat, and the water outlet is connected to one end of the connecting pipe.

[0040] Refer to Figures 1-10 , an alloy wire hot drawing and cooling device, including a hollow outer shell 1, wherein the outer shell 1 is arranged at the wire outlet end of the wire drawing die. Further, the outer shell is detachably installed on the side wall of the wire drawing machine through bolts provided on the outer wall.

[0041] Refer to Figures 1-8 , the outer shell 1 in this embodiment is hollow, the inner diameters of its inner walls are 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. In some embodiments, the inner cavity of the cooling seat 3 is a frustum cavity structure. Specifically, the inner diameter of the inner cavity of the cooling seat 3 at the end far from the wire drawing die is larger than the inner diameter of the other end. Based on this frustum structure, it helps the coolant to converge to the bottom of the inner cavity of the cooling seat 3 under the action of its own gravity.

[0042] Among them, the coolant is a liquid such as water or oil.

[0043] A first cooling chamber 300 is provided inside the cooling base 3. The first cooling chamber 300 is annularly arranged inside the cooling base 3. The outer diameter of the wire body to be cooled is smaller than the minimum inner diameter of the inner cavity of the cooling base 3, ensuring that the coolant ejected from the first cooling chamber 300 acts on the outer wall of the wire body to be cooled.

[0044] In some embodiments, the structure of the first cooling chamber 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 base 3 and communicates with the first cooling chamber 300. In addition, there are multiple cooling ports 301 which are annularly arranged at equal distances on the inner wall of the cooling base 3. Then, after the coolant in the first cooling chamber 300 is ejected from the cooling ports 301, it adheres to the outer wall of the wire body to be cooled, realizing the heat exchange between the cooling liquid and the wire body to be cooled.

[0045] Based on the setting of the cooling base 3, the structure of the coolant recovery system flowing out from the inner wall of the cooling base 3 is set as follows: A diversion groove 302 is provided at the bottom of the cooling base 3. The diversion groove 302 is circular arc-shaped and arranged at the bottom of the cooling base 3. Preferably, the central angle of the diversion groove 302 is 45°. Further, a water storage tank 5 is arranged on the outer wall of the outer shell 1 for collecting the coolant flowing out from the diversion groove 302. The structure for guiding the coolant from the diversion groove 302 to the water storage tank 5 is a flow channel 100 arranged inside the outer shell 1. The flow channel 100 is arc-shaped, and the central angle of the flow channel 100 is smaller than that of the diversion groove 302. At the same time, the inlet of the flow channel 100 is located inside the diversion groove 302, which helps to guide the coolant in the diversion groove 302 to the flow channel 100. In addition, a supply pipe and a liquid outlet pipe are arranged on the outer wall of the water storage tank 5 for replenishing the coolant into the water storage tank 5 and discharging the coolant respectively.

[0046] Refer to Figures 3-8 As shown in the figure, a cooling clamping cylinder 2 slides horizontally inside the outer shell 1 and is used for further cooling the wire body to be cooled. After the cooling clamping cylinder 2 clamps the outer wall of the wire body to be cooled, it moves synchronously with the wire body to be cooled. Further, the coolant flowing through the cooling clamping cylinder 2 cools the wire body to be cooled clamped inside it.

[0047] First of all, the cooling clamping cylinder 2 includes a driving shell base 200 and a cooling chamber base 201. The driving shell base 200 is hollow, and there are two cooling chamber bases 201, which are respectively composed of an upper clamping seat 2010 and a lower clamping seat 2011. When the upper clamping seat 2010 and the lower clamping seat 2011 are fitted together, they clamp the alloy wire to be cooled. Among them, the upper clamping seat 2010 and the lower clamping seat 2011 linearly slide inside the hollow cavity of the driving shell base 200.

[0048] It should be noted that the driving housing base 200 slides horizontally in the outer housing 1 through a driving member. In some embodiments, the driving member can be a wire or a screw. When the driving member is a wire, the horizontal linear movement of the driving housing base 200 in the outer housing 1 is achieved by winding or unwinding the wire. In this embodiment, the driving housing base 200 also needs to be connected to a reset tension spring to ensure the reset after the driving housing base 200 is pulled. When the driving member is a screw, the driving housing base 200 is threadedly connected to the screw, and the horizontal linear movement of the driving housing base 200 in the outer housing 1 is achieved by the rotation of the screw. However, the driving member is not limited to the above two structures, and any structure that can achieve the horizontal linear movement of the driving housing base 200 is acceptable.

[0049] In addition, to ensure the stable sliding of the driving housing base 200 and the stable linear sliding between the driving housing base 200 and the outer housing 1, the driving housing base 200 can be constrained by a sliding seat and a sliding rail.

[0050] Refer to Figures 3-8 , a second cooling cavity 202 and a third cooling cavity 203 are provided in the cooling cavity base 201. Further, the second cooling cavity 202 is located between the first cooling cavity 300 and the third cooling cavity 203. In addition, the second cooling cavity 202 and the third cooling cavity 203 are enclosed spaces in the cooling cavity base 201.

[0051] In addition, a water storage tank 5 is further provided on the outer wall of the outer housing 1. Based on the settings of the first cooling cavity 300, the second cooling cavity 202, and the third cooling cavity 203, the implementation method of temperature control in this embodiment is as follows:

[0052] The inlet end of the first cooling cavity 300 is communicated with the outlet end of the second cooling cavity 202, and the communication structure can be achieved through a first connecting pipe 4;

[0053] The inlet end of the second cooling cavity 202 is communicated with the outlet end of the third cooling cavity 203, and the communication structure can be achieved through a third connecting pipe 8;

[0054] The inlet end of the water storage tank 5 is communicated with the outlet end of the first cooling cavity 300, and the connection structure is achieved through a flow channel 100, which is conducive to heat dissipation and reduces the temperature of the coolant; the outlet end of the water storage tank 5 is communicated with the inlet end of the third cooling cavity 203, and the communication structure can be achieved through a second connecting pipe 7;

[0055] Among them, the first connecting pipe 4, the second connecting pipe 7, and the third connecting pipe 8 are all hose structures; it should be added that the flow of the coolant in the first connecting pipe 4, the second connecting pipe 7, and the third connecting pipe 8 is provided with kinetic energy by a first water pump body 6 provided in the water storage tank 5. Specifically, one end of the second connecting pipe 7 is fixed on the output end of the first water pump body 6;

[0056] 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, and the second and third stages are the wrapped cooling stages. The specific implementation methods of the three stages are as follows:

[0057] First stage: The coolant in the first cooling chamber 300 is ejected from the cooling port 301 and sprayed onto the outer wall of the wire body located in the middle of the cooling seat 3. Heat exchange with the wire body is achieved through the coolant attached to the outer wall of the wire body;

[0058] Second stage: The upper clamp seat 2010 and the lower clamp seat 2011 of the cooling chamber seat 201 clamp the wire body, causing the cooling chamber seat 201 and the wire body to move synchronously and at the same speed. The coolant in the second cooling chamber 202 flows, and heat exchange with the wire body is achieved through the transfer of the cooling chamber seat 201;

[0059] Third stage: This stage is the same as the second stage. After the cooling chamber seat 201 clamps the wire body, the coolant in the third cooling chamber 203 flows, and heat exchange with the wire body is achieved through the transfer of the cooling chamber seat 201;

[0060] In the above three stages, the process of heat exchange is carried out separately. 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. Among them, the first cooling chamber 300, the second cooling chamber 202, and the third cooling chamber 203 are cooled in sequence along the movement direction of the wire body;

[0061] Furthermore, the temperature of the coolant in the first cooling chamber 300 is the temperature of the coolant after absorbing heat in the second cooling chamber 202, which makes the temperature difference between the coolant temperature and the wire body temperature just after leaving the hot drawing die smaller; furthermore, the temperature of the coolant in the second cooling chamber 202 in the second stage is the temperature of the coolant after absorbing heat in the third cooling chamber 203, which makes the temperature difference between the coolant temperature and the wire body temperature just after leaving 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 coolant in the first cooling chamber 300 absorbs heat and cools down, which makes the temperature difference between the coolant temperature and the wire body temperature just after leaving the second stage smaller. Thus, it can be seen that the coolant temperature in the first stage to the third stage decreases in sequence, and the coolant temperature in the first stage and the second stage does not require an external heating structure to adjust the temperature. It completely relies on the coolant that absorbs heat behind the wire body to replenish the coolant at the front end, achieving an energy-saving effect.

[0062] It should be added that: The coolant flowing out from the first stage flows through the flow channel 100 and flows towards the water storage tank 5. During this process, the flow channel 100 is arranged along the outer housing 1. Then, when the coolant flows in the flow channel 100, the coolant dissipates heat to the outside through the outer housing 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 coolant temperature in the second stage.

[0063] Reference Figures 3-8 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:

[0064] 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.

[0065] 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.

[0066] 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.

[0067] In some embodiments, based on the arrangement of the through-ports 901, to prevent the T-shaped slide 204 from prematurely misaligning and entering a non-designated through-port 901 during the movement of the cooling cartridge 2 along the wire body, the horizontal end length of the T-shaped slide 204 at the end away from the cooling seat 3 is less than that of the other T-shaped slide 204, and at the same time, the horizontal end width of the T-shaped slide 204 at the end away from the cooling seat 3 is greater than that of the other T-shaped slide 204. During use, the four through-ports 901 are divided into two groups, and the shapes of the two groups of through-ports 901 are the same as the outer shapes of the horizontal ends of the two T-shaped slides 204. Based on the matching of the shape alignment features, it is ensured that the T-shaped slide 204 will not enter a non-designated through-port 901. Further, it is ensured that during the movement of the cooling cartridge 2 along the wire body or when the cooling cartridge 2 returns to the initial state, the upper clamp seat 2010 and the lower clamp seat 2011 maintain the clamping or separating state. Only when the cooling cartridge 2 is at the end close to the cooling seat 3 or at the end away from the cooling seat 3 can the clamping or separating state of the upper clamp seat 2010 and the lower clamp seat 2011 be adjusted.

[0068] Referring to Figures 3-8 , in some embodiments, the extrusion member is the connecting seat 10 and two through-port abutting portions 101 provided on the connecting seat 10, and the two through-port abutting portions 101 face the two through-ports 901 close to the cooling seat 3. Then, when the cooling cartridge 2 moves to the outermost end close to the cooling seat 3, the two connecting seats 10 move relative to each other, so that the through-port abutting portions 101 abut against the T-shaped slide 204, causing the T-shaped slide 204 to move out of the through-port 901 towards the outside of the U-shaped slide rail 9 until the side walls of the through-port abutting portions 101 are flush with the opposite side walls 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, moving in the same direction and at the same speed as the wire body. It should be added that: the driving force for the linear movement of the connecting seat 10 can be a cylinder or a screw driven by 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 linear movement of the connecting seat 10 can be used.

[0069] It should be added that: the distance for the cooling cartridge 2 to move synchronously and at the same speed as the wire body is between half of the length of the cooling cartridge 2 and the length of the cooling cartridge 2. In this way, after the cooling cartridge 2 completes the temperature reduction treatment in the second and third stages after moving along the wire body for one round, the next clamping position still has the same area as the previous clamping, so that the cooling cartridge 2 covers the entire flowing wire body during clamping, and there will be no dead zone for wire body cooling.

[0070] In addition, this embodiment also discloses a control structure for adjusting the inlet temperature of the coolant in the first cooling chamber 300 and the second cooling chamber 202. The adjustment principle is to adjust the flow distance of the coolant in the second cooling chamber 202 and the third cooling chamber 203. Referring to Figures 3-8 , the structure is arranged as follows:

[0071] When adjusting the inlet temperature of the coolant in the first cooling chamber 300, an outlet plug seat 11 is horizontally slidably connected in the second cooling chamber 202. The outlet end of the second cooling chamber 202 is a water outlet provided on the outlet plug seat 11. The water outlet is communicated with one end of the first 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, so that the heat exchange flow rate, time, etc. of the coolant in the second cooling chamber 202 through the cooling chamber seat 201 and the wire body are changed, the temperature of the coolant flowing out of the second cooling chamber 202 is changed, and further the temperature of the coolant entering the first cooling chamber 300 is changed;

[0072] When adjusting the inlet temperature of the coolant in the second cooling chamber 202, an inlet plug seat 12 is horizontally slidably connected in the third cooling chamber 203. The inlet end of the third cooling chamber 203 is a water inlet provided on the inlet plug seat 12. The water inlet is communicated with one end of the second connecting pipe 7. 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, so that the heat exchange flow rate, time, etc. of the coolant in the third cooling chamber 203 through the cooling chamber seat 201 and the wire body are changed, the temperature of the coolant flowing out of the third cooling chamber 203 is changed, and further the temperature of the coolant entering the second cooling chamber 202 is changed.

[0073] It should be added that the horizontal movement of the outlet plug seat 11 and the inlet plug seat 12 can be realized by linear drive electronic components such as cylinders.

[0074] It can be seen that by changing the actual flow distance of the coolant in the second cooling chamber 202 and the third cooling chamber 203, the temperatures of the coolant entering the first cooling chamber 300 and the second cooling chamber 202 can be adjusted, so as to control the temperature difference between the coolant and the wire body, which helps to slowly cool the wire body in stages.

[0075] In this embodiment, referring to Figure 9 , in order to facilitate the independent control of the water volume, flow rate, etc. of the three cooling chambers of the first cooling chamber 300, the second cooling chamber 202 and the third cooling chamber 203, and not adopt the unified control method of the first water pump body 6, water storage tanks 15 are connected to both the first connecting pipe 4 and the third connecting pipe 8, and a second water pump body 13 is arranged in the water storage tank 15. Specifically, the water storage tank 15 on the first connecting pipe 4 and the second water pump body 13 therein regulate the flow rate, flow volume, etc. of the coolant entering the first cooling chamber 300; the water storage tank 15 on the third connecting pipe 8 and the second water pump body 13 therein regulate the flow rate, flow volume, etc. of the coolant entering the second cooling chamber 202; the water storage tank 5 and the first water pump body 6 therein regulate the flow rate, flow volume, etc. of the coolant entering the third cooling chamber 203.

[0076] In some embodiments, referring toFigure 10 , 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: Rubber sealing seats 14 that can move radially are connected in the first cooling cavity 300, the second cooling cavity 202, and the third cooling cavity 203. When the rubber sealing seats 14 move 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. Relatively speaking, the temperature of the coolant flowing out of the second cooling cavity 202 and the third cooling cavity 203 can also be regulated. On the contrary, when the rubber sealing seats 14 move 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.

[0077] It should be added that the movement of the rubber sealing seats 14 can be realized by linear drive electronic components such as cylinders.

[0078] Finally, in this embodiment, in order to accurately control the temperature, flow rate, etc. of the coolant flowing into the first cooling cavity 300, the second cooling cavity 202, and the third cooling cavity 203, solenoid valves, temperature sensors, and flow sensors are provided in the first connecting pipe 4, the second connecting pipe 7, the third connecting pipe 8, and the flow channel 100. The setting of the solenoid valve controls the flow velocity and flow rate of the coolant. The temperature sensor senses the temperature of the coolant entering each cooling cavity to determine whether it meets the set temperature. When it does not meet the set temperature, the temperature of the coolant flowing out of the second cooling cavity 202 and the third cooling cavity 203 is adjusted. The flow sensor senses the flow rate of the coolant entering each cooling cavity to determine whether it meets the set flow rate. When it does not meet the set flow rate, the position of the rubber sealing seat 14 or the opening size of the solenoid valve is adjusted.

[0079] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
