Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing machines, and particularly relates to a direct-drive ultra-fine wire drawing machine with a cooling function and a method therefor. Background Art

[0002] An ultra-fine wire drawing machine is a device used to process metal raw materials into fine metal wires through a stretching or drawing process. This process uses specific mechanical means to process metal materials into metal wire rods with high diameter accuracy and smooth surfaces. However, a large amount of heat is generated during the stretching process, so a cooling structure needs to be provided on the ultra-fine wire drawing machine. However, the existing ultra-fine wire drawing machines with cooling functions still have the following defects during use: For example, Chinese Patent Publication No. CN222198347U discloses an ultra-fine wire drawing machine with a cooling function, including a device frame. A transmission frame is installed on the device frame. A roller is arranged on one side of the transmission frame. A limiting roller is connected to one side of the roller. A metal wire is connected inside the limiting roller. A wire drawing box is also installed on the device frame. A heating coil is arranged inside the wire drawing box. A wire drawing block is installed on one side of the heating coil. An annular outer tube is arranged outside the wire drawing block. In this solution, the possibility of material damage or deformation caused by the accumulation of internal heat during the wire drawing process is reduced. The possibility of the metal wire breaking due to a rapid temperature drop during wire drawing is reduced. The stability of the metal wire during transportation is improved, and it is more convenient to collect. Also, the cooling effect of the device is improved, and appropriate cooling can be performed to avoid damage caused by rapid cooling.

[0003] Since a large amount of heat is generated during the drawing of fine wires, the temperature of the surface layer of the drawn piece will be very high, while the temperature of the inner core is relatively low, resulting in a large temperature gradient. The inner core of the drawn piece will bear a large tensile stress, and the annular part outside the middle will bear a large compressive stress. Microcracks and other defects are likely to occur inside the finished product during wire drawing under a large temperature gradient, leading to product scrapping. Summary of the Invention

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1 - 12 , a direct drive ultra-fine wire drawing machine with a cooling function, as shown in Figures 1 - 4As shown in the figure, it includes a frame 1, on which a wire drawing mechanism 3 and a winding mechanism 4 are arranged; the wire drawing mechanism 3 includes a wire drawing box 31 with a mounting plate 32 arranged on the frame 1, a wire drawing block 33 is mounted on the mounting plate 32, and a thin wire 5 passes through the wire drawing block 33 in the wire drawing box 31 and is connected to the winding mechanism 4; the winding mechanism 4 includes a motor 41 mounted on the frame 1, the output end of the motor 41 is coaxially connected with a winding wheel 42, and one end of the thin wire 5 is wound around the winding wheel 42; the wire drawing mechanism 3 further includes a temperature control mechanism 34; the temperature control mechanism 34 includes: a heater 341, a cooler 342, a first temperature detector 343, a second temperature detector 344 and a third temperature detector; among them, the heater 341 is mounted on the wire drawing box 31 and is used to heat the thin wire 5 so that the inner core and the surface of the thin wire 5 maintain the same temperature; the cooler 342 is mounted on the wire drawing box 31 and is used to lower the surface temperature of the thin wire 5; the heater 341, the cooler 342 and the wire drawing block 33 are arranged in sequence along the conveying direction of the thin wire 5; the first temperature detector 343 is arranged between the heater 341 and the cooler 342 and is used to detect the surface temperature of the thin wire 5 after being heated by the heater 341; the second temperature detector 344 is arranged between the cooler 342 and the wire drawing block 33 and is used to detect the surface temperature of the thin wire 5 after being cooled by the cooler 342 before wire drawing; the third temperature detector is arranged in the wire drawing box 31 and is used to detect the surface temperature of the thin wire 5 after being drawn by the wire drawing block 33; it can be understood that the first temperature detector 343, the second temperature detector 344 and the third temperature detector are all prior arts, such as infrared temperature detectors, which can measure the surface temperature of the thin wire 5 non-contact, and will not be elaborated in detail.

[0021] It should be noted that, first of all, the motor 41 drives the winding wheel 42 to rotate, driving the thin wire 5 to pass through the wire drawing block 33 for wire drawing. During this process, the heater 341 and the cooler 342 are not started temporarily, and the wire drawing work is only completed by relying on the wire drawing block 33. Subsequently, the surface temperature of the thin wire 5 is detected by the third temperature detector, and this temperature value is recorded as K; When the wire drawing work is officially carried out, as the winding wheel 42 rotates to wind the thin wire 5, the heater 341 is started to heat the thin wire 5 so that its inner core and surface temperature reach the previously recorded temperature value K, and it is detected and verified by the first temperature detector 343. Subsequently, when the heated thin wire 5 moves to the position of the cooler 342, the cooler 342 cools the surface of the thin wire 5, and the cooling range is K, which is detected and verified by the second temperature detector 344. The cooled thin wire 5 enters the position of the wire drawing block 33 for wire drawing work. During the wire drawing process, the temperature of the thin wire 5 will rise, and the rising range is K, which exactly offsets the temperature of the surface of the thin wire 5 cooled by the cooler 342 before, so that the inner core and the surface temperature of the drawn thin wire 5 are close to the same, realizing the temperature balance in the wire drawing work. This temperature balance can ensure that the thin wire 5 is uniformly stressed and has a uniform microstructure during the stretching process, thereby effectively improving the finished product quality of the thin wire 5; It is understandable that, in order to ensure the accuracy of temperature control, the wire drawing machine can be used in a constant temperature environment.

[0022] Please refer to Figures 1 - 4 , the heater 341 includes a spiral heating tube 3411, and the cooler 342 includes a spiral cooling tube 3421; both the heating tube 3411 and the cooling tube 3421 are coaxially sleeved on the thin wire 5; it is understandable that by sleeving the heating tube 3411 and the cooling tube 3421 around the thin wire 5 in a spiral shape, uniform heating and cooling of the thin wire 5 can be achieved, thereby effectively ensuring the temperature control effect on the thin wire 5.

[0023] Please refer to Figures 5 - 8 , the wire drawing mechanism 3 further includes a lubrication mechanism 35; the lubrication mechanism 35 is installed on the frame 1 and is used to lubricate and cool the friction position between the wire drawing block 33 and the thin wire 5; the lubrication mechanism 35 includes a storage tank 351, a micro pump 352, a delivery pipe 353, a storage ring 354, a spiral pipe 356, and a rotating ring 3571; the rotating ring 3571 is coaxially rotatably connected to the wire drawing block 33, and a plurality of spray holes 355 are circumferentially arrayed on the rotating ring 3571, the storage tank 351 is arranged in the wire drawing box 31, and the storage tank 351 is filled with lubricating fluid; the micro pump 352 is installed in the wire drawing box 31, the input end of the micro pump 352 is connected to the bottom of the storage tank 351 through the delivery pipe 353, the storage ring 354 is sleeved on the rotating ring 3571, the inside of the storage ring 354 is communicated with the wire drawing hole of the wire drawing block 33 through the spray holes 355, and the output end of the micro pump 352 is communicated with the storage ring 354 through the delivery pipe 353; the spiral pipe 356 is arranged in the storage ring 354, and the spiral pipe 356 is sleeved on the cooling tube 3421.

[0024] It should be noted that during the wire drawing process, the micro pump 352 exports the lubricating fluid in the storage tank 351 to the storage ring 354 through the delivery pipe 353 and sprays it evenly on the circumferential side of the thin wire 5 from a plurality of spray holes 355. The spraying of the lubricating fluid can not only reduce the friction between the thin wire 5 and the wire drawing block 33, but also play a certain role in cooling the thin wire 5 and the wire drawing block 33. Most of the used lubricating fluid is re-introduced into the storage tank 351, filtered and then stored again, so as to realize the recycling of the lubricating fluid. In addition, by sleeving the spiral pipe 356 on the cooling tube 3421, the circulating lubricating fluid is cooled to ensure that the lubricating fluid always maintains good lubrication and cooling effects during the circulation process, and to ensure the smooth progress of the wire drawing process.

[0025] Please refer to Figures 7 - 10, the lubrication mechanism 35 further includes a control mechanism 357 and is used to drive the rotation of the rotating ring 3571; the control mechanism 357 includes a worm gear 3575, a worm 3576 and a driving member 3577; the worm gear 3575 is coaxially fixed to the rotating ring 3571, the worm 3576 is installed on the mounting plate 32, and the worm gear 3575 is meshed with the worm 3576; the driving member 3577 is installed on the wire drawing box 31 and is used to drive the worm 3576 to rotate around its axis; it can be understood that the driving member 3577 is a prior art and is not shown in the figure and will not be elaborated in detail.

[0026] It should be noted that, in order to further improve the uniformity of the distribution of the lubricating fluid between the thin wire 5 and the wire drawing block 33, by driving the rotation of the rotating ring 3571, the spray holes 355 are driven to rotate, so that the lubricating fluid is ejected in a rotating manner, thereby ensuring the uniform distribution of the lubricating fluid between the thin wire 5 and the wire drawing block 33. At the same time, this rotating ejection method can also flush out the impurities in the wire drawing block 33. The specific implementation method is: the driving member 3577 drives the worm 3576 to rotate, the worm 3576 drives the worm gear 3575 meshed with it to rotate, and then drives the rotating ring 3571 to rotate, finally realizing the rotating ejection of the lubricating fluid.

[0027] Please refer to Figures 7 - 10 , the control mechanism 357 further includes a baffle 3572 and a rubber plug 3574; the baffle 3572 is fixed to the storage tank 351, and the baffle 3572 is rotatably connected to the rotating ring 3571 coaxially, the rubber plug 3574 is arranged on the baffle 3572, and the thin wire 5 passes through the rubber plug 3574; a lead-out port 3573 is opened on the baffle 3572 and is used to lead out the lubricating fluid in the rotating ring 3571.

[0028] It should be noted that by providing the baffle 3572, the lubricating fluid can only be led out through the lead-out port 3573, thereby ensuring that the lubricating fluid stays between the thin wire 5 and the wire drawing block 33 for a long time, effectively improving the lubrication and cooling effects, and at the same time preventing the excessive splashing of the lubricating fluid. In addition, by providing the rubber plug 3574, the surface of the thin wire 5 can be cleaned before wire drawing, so as to ensure the wire drawing effect.

[0029] Please refer to Figures 9 - 12 , the wire drawing mechanism 3 further includes a positioning mechanism 36, and the positioning mechanism 36 includes a first positioning wheel 361 and a second positioning wheel 363; a mounting block is provided on the storage tank 351, the first positioning wheel 361 and the second positioning wheel 363 are both rotatably connected to the mounting block, and the axes of the first positioning wheel 361 and the second positioning wheel 363 are parallel, the thin wire 5 is arranged between the first positioning wheel 361 and the second positioning wheel 363, and when the thin wire 5 is drawn and conveyed, it can drive the first positioning wheel 361 and the second positioning wheel 363 to rotate.

[0030] It should be noted that a positioning mechanism 36 is provided to further ensure that the thin wire 5 is in a straightened state during the wire drawing process. When the thin wire 5 is conveyed, the squeezing action between the first positioning wheel 361 and the second positioning wheel 363 can straighten the thin wire 5 that may be in a bent state. At the same time, the thin wire 5 will drive the first positioning wheel 361 and the second positioning wheel 363 to rotate during the conveying process, so that a static friction is formed between the thin wire 5 and the first positioning wheel 361 and the second positioning wheel 363, effectively reducing the wear caused by sliding friction.

[0031] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that: Please refer to Figures 9 - 12 , the positioning mechanism 36 further includes a belt transmission mechanism 364; one end of the belt transmission mechanism 364 is connected to the second positioning wheel 363, and the other end of the belt transmission mechanism 364 is connected to the worm 3576; the belt transmission mechanism 364 is used to transmit the rotational force driving the second positioning wheel 363 to the worm 3576 to drive the worm 3576 to rotate.

[0032] It should be noted that in order to drive the rotating ring 3571 to rotate, the original driving member 3577 can be replaced with a belt transmission mechanism 364. During the conveying process of the thin wire 5, the second positioning wheel 363 will rotate due to the conveying of the thin wire 5. Through the cooperation of the belt transmission mechanism 364, the rotation of the second positioning wheel 363 can transmit power to the worm 3576, and then drive the worm 3576 to rotate. After the worm 3576 rotates, it drives the worm gear 3575 meshed with it to rotate, and finally realizes the rotation of the rotating ring 3571, so as to achieve the purpose of the lubricating liquid rotating and spraying out.

[0033] Please refer to Figures 11 - 12 , the positioning mechanism 36 further includes a second adjusting mechanism 365. The second adjusting mechanism 365 includes a rotating shaft 362, a second threaded adjusting rod 3652, an adjusting plate 3653, a pair of adjusting blocks 3651 and a spring 3654; a chute is opened on the mounting block, the rotating shaft 362 is slidably connected to the chute, and the second positioning wheel 363 is coaxially fixed to the rotating shaft 362; a pair of adjusting blocks 3651 are respectively sleeved on both ends of the rotating shaft 362, the second threaded adjusting rod 3652 is rotatably connected to the mounting block, the adjusting plate 3653 is arranged above the mounting block, and the second threaded adjusting rod 3652 is threadedly connected to the adjusting plate 3653, and the adjusting plate 3653 and the adjusting block 3651 are connected by a spring 3654.

[0034] It should be noted that by rotating the second threaded adjusting rod 3652, the adjusting plate 3653 is driven to move in a predetermined direction. During this process, the spring 3654 exerts a certain force on the adjusting block 3651, enabling the adjusting block 3651 to adjust its position accordingly. In this way, the distance between the first positioning wheel 361 and the second positioning wheel 363 can be changed, thereby indirectly adjusting the extrusion pressure of the first positioning wheel 361 and the second positioning wheel 363 on the thin wire 5, achieving precise control of the pressure on the thin wire 5.

[0035] Please refer to Figure 1 , a first adjusting mechanism 2 is provided on one side of the wire drawing box 31 and is used to adjust the tension degree of the thin wire 5; the first adjusting mechanism 2 includes a plurality of guide wheels 21, an adjusting wheel 22, a slider 23, and a first threaded adjusting rod 24; the plurality of guide wheels 21 and the adjusting wheel 22 are respectively arranged on the upper and lower sides of the thin wire 5, the adjusting wheel 22 is slidably connected to the frame 1 through the slider 23, the first threaded adjusting rod 24 is threadedly connected to the frame 1, and the bottom of the first threaded adjusting rod 24 is rotatably connected to the slider 23. By driving the first threaded adjusting rod 24 to rotate, the position of the adjusting wheel 22 is adjusted to control the clamping force of the guide wheels 21 and the adjusting wheel 22 on the thin wire 5.

[0036] Please refer to Figures 1 - 13 , a direct-driven ultra-fine wire drawing method with a cooling function, using the above-mentioned direct-driven ultra-fine wire drawing machine with a cooling function, specifically includes the following steps: Step 1. Wire drawing temperature detection: Start the winding mechanism 4, make the thin wire 5 pass through the wire drawing block 33, and start the wire drawing work; at the same time, start the third temperature detector to detect the surface temperature K of the thin wire 5 after wire drawing by the wire drawing block 33, and complete the temperature test work before the formal wire drawing. Step 2. Wire drawing temperature control: Start the winding mechanism 4. Before the thin wire 5 enters the wire drawing block 33, it is first heated to the set temperature K by the heater 341, and the first temperature detector 343 detects and confirms that the temperature reaches the standard; then, the thin wire 5 enters the cooler 342 for surface cooling, and the cooling range is K. After being detected by the second temperature detector 344, it is ensured that the surface temperature drops to the required range; after the heating and cooling treatments are completed, the thin wire 5 passes through the wire drawing block 33 for wire drawing, and finally the core and surface temperatures of the drawn thin wire 5 are kept close to each other, completing the temperature regulation and detection work before wire drawing.
