Description

Technical Field

[0001] This invention relates to the field of metal wire drawing equipment technology, specifically to a wire feeding device for a wire drawing machine and a wire drawing machine. Background Technology

[0002] In the metal wire drawing process, after the wire is drawn from the unwinding reel, it needs to undergo a shaking process to eliminate residual stress, followed by straightening to ensure ovality, and finally drawing into shape using a drawing die. The shaking process is a crucial step in the unwinding stage, and its effectiveness directly affects the internal stress distribution of the wire and the subsequent drawing quality. In existing technologies, the unwinding device of a wire drawing machine is usually equipped with a shaking mechanism, which releases the residual stress generated in the wire during the drawing process by driving the wire in a reciprocating motion.

[0003] Currently available wire-shaking mechanisms generally employ a single vertical or horizontal reciprocating motion mode, applying only a single-dimensional shaking force to the wire. This fails to simulate the multi-dimensional, complex actions of hand-rubbing, kneading, shaking, and pulling, resulting in incomplete removal of residual stress within the wire and affecting the ovality and surface quality of the finished wire. Furthermore, the shaking frequency and amplitude of existing mechanisms are preset fixed values, unable to be dynamically adjusted according to changes in wire material and diameter. This leads to poor adaptability to different wire specifications, requiring manual resetting when processing parameters change, which is cumbersome and makes it difficult to guarantee optimal wire-shaking results. Summary of the Invention

[0010] Preferably, a horizontal cylinder and a vertical cylinder are respectively installed at the end of the wire drawing die. The horizontal cylinder and the vertical cylinder form a straightening structure to ensure the ellipticity of the wire is maintained.

[0011] Preferably, a wire feeding reel is installed on the side end of the frame of the horizontal cylinder and the vertical cylinder.

[0012] Preferably, the wire feeding reel is connected to a wire guide wheel via a wire, and the side end of the wire guide wheel is respectively equipped with a swing arm and an elastic tension adjustment structure.

[0013] Preferably, an adaptive controller is installed on the side of the pay-off reel, and the adaptive controller is electrically connected to the circumferential angle rotation structure, the XY moving platform, the push guide rod, the flexible finger, the drive structure, and each sensor.

[0014] Preferably, the adaptive controller adjusts the motion trajectory of the circumferential angle rotation structure, the XY moving platform, and the bending angle of the flexible finger in real time according to the wire condition collected by the infrared detection end and the wire diameter detection end, so that the shaking of the wire is dynamically matched with the wire condition.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the wire-laying assembly, in conjunction with a circumferential angle rotation structure, achieves rotational adjustment around a vertical axis.

During operation, the wire passes through the wire-laying frame structure. The adaptive controller controls the XY moving platform to drive the wire-laying frame structure in a three-dimensional composite motion. Simultaneously, a bidirectional drive motor, via a reciprocating lead screw guide, drives the flexible finger to reciprocate along the axis, rubbing and twisting. The drive structure adjusts the swing angle of the flexible finger, achieving multi-dimensional biomimetic movements that simulate the rubbing, kneading, shaking, and pulling motions of a human hand.

[0016] During the wire shaking process, a triaxial force sensor, pressure sensor, vibration detection device, and infrared detection end collect data in real time and calculate the residual stress release index. The adaptive controller dynamically optimizes the shaking data based on this index, forming a closed-loop control and updating the batch data to the global model to achieve self-learning. The overall design, through flexible fingers and a drive structure set on the shaking frame, achieves flexible contact with the wire, avoiding rigid scratches. Simultaneously, through precise control of the first and second drive gear components, it applies a controllable, wide-range varying kneading force to the wire, ensuring surface quality while efficiently releasing internal stress. This effectively solves the contradiction in existing technologies where increasing the shaking force easily damages the wire, while decreasing the force results in insufficient stress release.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1 , Figures 3-6As shown: A wire feeding device for a wire drawing machine includes: a frame 100 for supporting various structures; a wire feeding assembly 150 installed inside the frame 100; the wire feeding assembly 150 includes: a circumferential angle rotation structure 151, which includes a rotary drive motor and a rotary platform. Driven by the rotary drive motor, the rotary platform can rotate within a range of 0° to 360° around a vertical axis to adjust the angle of the entire wire feeding assembly 150 relative to the wire axis, thereby changing the angle between the wire feeding direction and the wire axis to achieve different rubbing effects; an XY moving platform 152 installed on top of the circumferential angle rotation structure 151, which includes an X-axis guide rail arranged horizontally and a Y-axis guide rail arranged vertically, wherein the X-axis guide rail and the Y-axis guide rail are perpendicularly intersecting to form a planar motion platform. A push guide rod 1521 is installed on the top of the Y-axis guide rail of the XY moving platform 152, and a wire feeding frame is installed on the top of the push guide rod 1521. A triaxial force sensor is installed between the connecting rod 154, the XY moving platform 152, and the push guide rod 1521. The triaxial force sensor is used to detect the force on the shaking frame connecting rod 154 in the X, Y, and Z directions in real time, and transmit the detection signal to the adaptive controller. The shaking frame structure 155 is fixed to the end of the shaking frame connecting rod 154 and is used to contact the wire and apply shaking force. The vertical sliding frame 153 is slidably connected to the side of the shaking frame connecting rod 154. The rod 154 can slide back and forth in the vertical direction along the vertical sliding frame 153, thereby adjusting the vertical height of the wire frame structure 155. At least one set of flexible fingers 105 is installed on the wire frame structure 155. Each flexible finger 105 has a flexible pressure contact 106 installed on its side wall surface. The flexible fingers 105 include multiple sets of upper flexible fingers and multiple sets of lower flexible fingers. The upper flexible fingers are located at the upper part of the wire frame structure 155, and the lower flexible fingers are located at the lower part of the wire frame structure 155. The upper and lower flexible fingers 105 are staggered. Each flexible finger 105 has a flexible pressure contact 106 installed on its side wall surface. The flexible pressure contact 106 is used to directly contact the wire surface to avoid damage to the wire surface caused by rigid contact. The connecting end of the flexible finger 105 is provided with a hinged connector 157. The arc plate 159 is installed between the upper and lower opposing flexible fingers 105. A vibration detection device is installed on the surface of the arc plate 159. The vibration detection device is set on one side of the wire surface in a non-contact manner.

[0021] The wire-laying assembly 150 further includes: multiple sets of miniature electromagnetic guide rods 102, which are mounted on the surface of the arc plate 159; flexible abutment balls 101 are mounted on the side of the miniature electromagnetic guide rods 102 for contacting one side of the wire surface; the miniature electromagnetic guide rods 102 can be independently controlled to extend and retract; when it is necessary to increase the local kneading force, the miniature electromagnetic guide rods 102 are extended to make the flexible abutment balls 101 contact the wire surface and apply additional local pressure; when it is necessary to reduce the kneading force, the miniature electromagnetic guide rods 102 are retracted to disengage the flexible abutment balls 101 from the wire surface.

[0022] The vibrating wire laying assembly 150 further includes: at least three bidirectional drive motors 158 mounted on the side of the vibrating wire frame structure 155; a reciprocating lead screw guide rail 156 mounted on both sides of the output end of the bidirectional drive motors 158, a reciprocating sliding member slidably connected on the bidirectional spiral guide rail of the reciprocating lead screw guide rail 156, and a miniature vertical electric guide rod 103 mounted on the side end of the reciprocating sliding member; and a drive structure 104 slidably connected to the miniature vertical electric guide rod 103, with the end of the drive structure 104 connected to the flexible finger 105. The drive structure 104 includes: a first drive gear 1041; a first half-gear rotating component 1042 meshing with the first drive gear 1041 for driving the flexible finger 105 to adjust its left and right angles; a second half-gear rotating component 1043 mounted on the side end of the flexible finger 105; and a second drive gear 1044 meshing with the second half-gear rotating component 1043 for driving the flexible finger 105 to adjust its up and down angles, so that the flexible finger 105 can contact the wire at different angles, simulating the complex movements of multiple finger joints in a human hand.

[0023] Specifically, the operator pre-processes the X-axis motion amplitude and frequency, Y-axis motion amplitude and frequency, rotation angle of the circumferential angle rotation structure 151, initial bending angle of each flexible finger 105, and initial extension and retraction of the micro electromagnetic guide rod 102 according to the material and diameter of the wire to be processed.

[0024] During operation, the wire is drawn out from the wire feeding mechanism, passes sequentially through the wire guide groove on the inlet side of the vibrating wire frame structure 155, the area between the upper and lower flexible fingers 105, and the arc-shaped concave area of ​​the arc plate 159, and finally exits from the wire guide groove on the outlet side of the vibrating wire frame structure 155 to enter the subsequent straightening module.

[0025] During this process, the wire guide groove ensures that the wire passes through the trembling frame structure 155 in the center, preventing the wire from rubbing against the edge of the trembling frame structure 155. At the same time, the adaptive controller controls the miniature vertical electric guide rod 103 to adjust the vertical position of the drive structure 104, so that the flexible pressure contact 106 of the flexible finger 105 maintains a preset initial contact pressure with the wire surface. This initial contact pressure is monitored in real time by the pressure sensor built into the flexible pressure contact 106 and fed back to the adaptive controller.

[0026] Subsequently, the adaptive controller issues a control command to initiate a multi-dimensional wire-shaking motion. Specifically, the adaptive controller controls the XY moving platform 152 to start, causing the X-axis and Y-axis guide rails to move the push guide rod 1521 in a composite motion in the horizontal plane according to a preset trajectory. This causes the push guide rod 1521 to drive the wire-shaking frame structure 155 in an elliptical or figure-eight trajectory in the horizontal plane via the wire-shaking frame connecting rod 154. Simultaneously, the reciprocating motion of the push guide rod 1521 on the Y-axis guide rail causes the wire-shaking frame connecting rod 154 to slide vertically along the vertical sliding frame 153, resulting in additional vertical displacement of the wire-shaking frame structure 155. Through the synthesis of these movements, the wire-shaking frame structure 155 forms a three-dimensional composite motion trajectory in space, applying a combined force simulating the rubbing, kneading, shaking, and pulling action of a human hand to the passing wire.

[0027] The adaptive controller starts the bidirectional drive motor 158, which in turn drives the reciprocating lead screw guide 156 to rotate. The reciprocating lead screw guide 156 drives the reciprocating slider to move reciprocally in a linear motion along the guide. The reciprocating slider drives the miniature vertical electric guide rod 103, the drive structure 104, and the flexible finger 105 to move reciprocally along the length of the wire frame structure 155, causing the flexible finger 105 to produce a rubbing effect along the axial direction on the wire surface. The adaptive controller controls the rotation of the first drive gear 1041 and the second drive gear 1044 in the drive structure 104. The first drive gear 1041 drives the first half-gear rotating component 1042, which meshes with it, to rotate. The first half-gear rotating component 1042 causes the flexible finger 105 to swing left and right in the horizontal plane, changing the angle of the contact point between the flexible finger 105 and the wire in the horizontal direction. The second drive gear 1044 drives the meshing second half-gear rotating component 1043 to rotate. The second half-gear rotating component 1043 causes the flexible finger 105 to swing up and down in the vertical plane, changing the angle between the flexible finger 105 and the wire in the vertical direction. Through the independent or combined adjustment of the above two degrees of freedom, the flexible finger 105 can contact the wire in various postures, just like simulating the fine movements of multi-finger operation of a human hand.

[0028] Furthermore, the adaptive controller selectively controls the extension and retraction of the miniature electromagnetic rod 102 based on preset wire shaking parameters. When it is necessary to increase the local kneading force, the miniature electromagnetic rod 102 extends, so that the flexible abutment ball 101 at its end contacts the wire surface, applying local pressure to a specific part of the wire and enhancing the stress release effect in that area; when it is necessary to reduce the kneading force or avoid excessive kneading, the miniature electromagnetic rod 102 retracts, so that the flexible abutment ball 101 disengages from the wire surface.

[0029] During the wire-shaking action, the adaptive controller continuously receives real-time detection signals from various sensors. This allows the triaxial force sensor, installed between the XY moving platform 152 and the push guide rod 1521, to detect the forces exerted on the wire-shaking frame connecting rod 154 in the X, Y, and Z directions in real time. These forces represent the components of the reaction force of the wire on the wire-shaking frame structure 155 in the three directions. This triaxial force signal reflects the overall interaction force between the wire-shaking frame structure 155 and the wire. The pressure sensor built into the flexible pressure contact member 106, installed on the sidewall surface of each flexible finger 105, detects the contact pressure between each flexible finger 105 and the wire in real time. The feedback contact pressure signal reflects the magnitude and distribution of the local pressure exerted by the flexible finger 105 on the wire.

[0030] The laser displacement sensor installed on the surface of the arc plate 159 detects the vibration frequency and amplitude of the wire in real time during the shaking process in a non-contact manner. The laser displacement sensor projects a laser beam onto the surface of the wire in a non-contact manner to detect the vibration frequency and amplitude of the wire in real time during the shaking process. The resulting signal reflects the dynamic response characteristics of the wire under the action of shaking.

[0031] The infrared detection terminal 110 installed at the wire inlet and outlet, or an acoustic emission sensor, detects the acoustic signals generated by changes in the internal microstructure of the wire in real time. The acoustic signals reflect the degree of residual stress release within the wire. The temperature distribution on the wire surface is also detected in real time; the temperature signal reflects the temperature changes caused by frictional heat generation and stress release during the wire shaking process. The adaptive controller fuses the detection signals from all the above sensors, extracting characteristic parameters such as the degree of residual stress release, the energy transfer efficiency of the shaking action, and the wire vibration modes, and calculates the residual stress release index of the current shaking action.

[0032] The adaptive controller compares the calculated residual stress release index with the index of the previous cycle to determine the direction of the line-shaking parameter adjustment. If the residual stress release index of the current cycle is higher than that of the previous cycle, it indicates that the current line-shaking parameter adjustment direction is correct, and the adaptive controller continues to adjust the line-shaking parameters in the same direction, including increasing or decreasing the motion amplitude and frequency of the XY moving platform 152, changing the rotation angle of the circumferential angle rotating structure 151, adjusting the swing angle and swing frequency of the flexible finger 105, and changing the extension and retraction timing of the micro electromagnetic guide rod 102, etc. If the residual stress release index of the current cycle is lower than that of the previous cycle, it indicates that the current line-shaking adjustment direction is incorrect, and the adaptive controller adjusts the line-shaking in the opposite direction to find a better adjustment combination.

[0033] During the above process, the adaptive controller adjusts the gain of each control variable. This ensures that after each jittering cycle, the adaptive controller uses the updated jittering parameters for the jittering action in the next cycle.

[0034] It should be noted that after a batch of wire of the same specification is processed, the adaptive controller records and stores the wire jitter parameters and corresponding residual stress release index of that batch of wire. The adaptive controller can compare and analyze this data with historical data to identify the optimal jitter adjustment force and angle for that specification of wire. This allows the adaptive controller to directly load the updated optimal jitter method when processing the same specification of wire again, without the need for readjustment, thereby shortening initialization time and improving production efficiency.

[0035] When the shaking action reaches the preset duration or the residual stress release index reaches the preset threshold, the adaptive controller determines that the shaking is complete. The adaptive controller sequentially stops the bidirectional drive motor 158, the XY moving platform 152, the circumferential angle rotation structure 151, and the drive structure 104 of each flexible finger 105. At the same time, the adaptive controller controls the miniature electromagnetic guide rod 102 to retract completely, so that the flexible contact ball 101 is no longer in contact with the wire surface; it controls the drive structure 104 to swing the flexible finger 105 back to its initial position, so that the flexible pressure contact 106 is no longer in contact with the wire surface or maintains minimal contact pressure. The wire, after being fully shaken, is led out from the wire guide groove on the exit side of the shaking frame structure 155 and enters the subsequent straightening structure for straightening, finally completing all the operations of the wire laying stage.

[0036] Preferred, according to Figures 1-2As shown, the wire drawing machine includes: an infrared detection end 110 mounted on the wire inlet and outlet of the frame 100; a take-up reel 120 mounted near the infrared detection end 110; two sets of wire diameter detection ends 180 for detecting wire diameter; and a wire drawing die 170 mounted near the wire diameter detection end 180. A horizontal cylinder 190 and a vertical cylinder 130 are respectively mounted at the end of the wire drawing die 170, forming a taut structure to ensure the ellipticity of the wire. A pay-off reel 140 is mounted on the side of the horizontal cylinder 190 and the vertical cylinder 130. The pay-off reel 140 is connected to a guide wheel 160 via the wire, and a swing arm 171 and an elastic tension adjustment structure 181 are respectively mounted on the side of the guide wheel 160. An adaptive controller is installed on the side of the wire reel 140. The adaptive controller is electrically connected to the circumferential angle rotation structure 151, the XY moving platform 152, the push guide rod 1521, the flexible finger 105, the drive structure 104, and each sensor. Based on the wire condition collected by the infrared detection end 110 and the wire diameter detection end 180, the adaptive controller adjusts the movement trajectory of the circumferential angle rotation structure 151, the XY moving platform 152, and the push guide rod 1521, as well as the bending angle of the flexible finger 105, in real time to dynamically match the wire shaking with the wire condition.

[0037] Specifically, the operator draws the wire from the pay-off reel 140, passes it sequentially around the guide wheel 160, through the shaking frame structure 155 of the shaking pay-off assembly 150, through the guide wheels of the horizontal cylinder 190 and vertical cylinder 130 of the straightening structure, through the drawing hole of the drawing die 170, and around the take-up reel 120, completing the wire threading. During the wire threading process, the adaptive controller controls the adjustment screw of the elastic tension adjustment structure 181 to achieve the preset initial tension of the tension spring. The elastic tension adjustment structure 181 is mounted on the side of the guide wheel 160 and is connected to the swing arm 171 for transmission. It applies an adjustable initial tension to the wire wound on the guide wheel 160, ensuring a stable and uniform tension before the wire enters the shaking pay-off assembly 150 and the drawing die 170. The elastic tension adjustment structure 181 adopts an electromechanical integrated adjustment method using a screw, tension spring, and sensor. Internally, it integrates an adjusting screw, a sliding nut seat, a helical tension spring, and a tension sensor, and is driven by a micro servo motor. When the adaptive controller calculates the required initial tension value based on the wire diameter, wire jitter parameters, or tautness, it controls the micro servo motor to rotate the screw, causing the sliding nut seat to move axially. This changes the initial tension length of the helical tension spring, adjusting the tension force applied to the swing arm 171. Under the action of the tension spring, the swing arm 171 drives the wire guide wheel 160 to generate radial pressure on the wire, thereby creating tension on the wire surface.

[0038] Meanwhile, the tension sensor built into the elastic tension adjustment structure 181 detects the actual tension value in real time and feeds it back to the adaptive controller, so that the adaptive controller compares the actual tension with the target tension and dynamically adjusts the action of the micro servo motor until the tension value converges within the allowable error range.

[0039] During continuous operation of the equipment, the elastic tension adjustment structure 181 can also adjust its tension setting value in real time according to the diameter fluctuations fed back by the wire diameter detection end 180, the shaking amplitude of the wire release assembly 150, and the air pressure changes of the straightening structure. When the wire diameter is too large or the shaking amplitude increases, the structure automatically increases the tension to improve the wire tension and prevent slippage or shaking; when the wire diameter is too small or the shaking amplitude decreases, it automatically decreases the tension to avoid excessive stretching and damage to the wire. The swing arm 171 applies initial tension to the wire guide wheel 160 to keep the wire in an appropriate tension state at the wire guide wheel 160. At the same time, the adaptive controller controls the miniature vertical electric guide rod 103 to adjust the vertical position of the drive structure 104 so that the flexible pressure contact 106 of the flexible finger 105 maintains a preset initial contact pressure with the wire surface. This initial contact pressure is monitored in real time by the pressure sensor built into the flexible pressure contact 106 and fed back to the adaptive controller to ensure that a stable initial contact is established between the flexible finger 105 and the wire.

[0040] The adaptive controller, based on the received tension sensor signal and wire-shaking parameters, causes the wire-shaking and unwinding assembly 150 to operate. Simultaneously with the wire-shaking and unwinding action, the adaptive controller performs straightening and wire-shaking linkage adjustment based on the wire-shaking data and wire diameter detection signal. The adaptive controller receives in real-time motion parameters of the wire-shaking frame structure 155, including X-axis motion amplitude, Y-axis motion amplitude, Z-axis rotation angle, and the oscillation frequency and amplitude of the flexible finger 105. Based on the aforementioned wire-shaking data, the adaptive controller calculates the degree of disturbance to the wire caused by the current wire-shaking action and adjusts the air pressure values ​​of the horizontal cylinder 190 and the vertical cylinder 130 accordingly.

[0041] Specifically, when the shaking motion has a large amplitude or high frequency, the wire's posture fluctuates significantly before entering the straightening structure. The adaptive controller increases the air pressure of the horizontal cylinder 190 and the vertical cylinder 130, causing the horizontal and vertical guide wheels to apply a greater straightening force to the wire, thus eliminating residual bending caused by the shaking motion. When the shaking motion has a small amplitude or low frequency, the adaptive controller reduces the cylinder air pressure, lowering the straightening force to avoid secondary damage to the wire caused by over-straightening. Simultaneously, the adaptive controller judges the wire diameter fluctuation based on the wire diameter detected by the upstream wire diameter detection end 180 before drawing. When a large fluctuation in wire diameter is detected, it indicates that there may be uneven deformation of the wire during the unwinding stage. The adaptive controller synchronously adjusts the shaking parameters of the unwinding assembly 150 and the cylinder pressure of the straightening structure to improve the wire condition from the source, ensuring that the wire entering the drawing die 170 has a uniform diameter and stable posture.

[0042] After being drawn from the straightening structure, the wire enters the drawing die 170, where it undergoes plastic deformation in the drawing hole, reducing its diameter to the target size. The adaptive controller receives the wire diameter signal before drawing from the upstream wire diameter detection end 180. If a deviation is detected between the pre-drawing wire diameter and the target value, the adaptive controller uses this deviation as a feedforward control variable to adjust the drawing speed of the drawing die 170 or the feeding speed of the feed reel 140 in advance, stabilizing the state of the wire entering the drawing die 170 and eliminating the impact of diameter deviation on the finished product quality. The adaptive controller also receives the finished wire diameter signal after drawing from the downstream wire diameter detection end 180. If a deviation is detected between the finished wire diameter and the target value, the adaptive controller uses this deviation as a feedback control variable to correct the drawing speed of the drawing die 170 or the take-up speed of the take-up reel 120, gradually bringing the finished wire diameter closer to the target value. Simultaneously, the adaptive controller fuses the feedforward and feedback control variables to update the feedforward and feedback composite control model. When the downstream wire diameter detection end 180 detects a diameter deviation, the adaptive controller provides feedback correction and, in conjunction with the built-in AI intelligence, performs self-learning correction.

[0043] After the finished wire is drawn out from the drawing die 170, it passes around the take-up reel 120 for winding. The take-up servo motor of the take-up reel 120 adjusts its speed according to the instructions of the adaptive controller to ensure that the take-up speed matches the drawing speed and avoid overstretching or loosening of the wire during winding. During the winding process, two sets of infrared detection terminals 110 installed near the take-up reel 120 continuously monitor the passing status of the wire. When the infrared detection terminal 110 detects that the wire is passing normally, the equipment continues to operate; when the infrared detection terminal 110 detects that the wire is interrupted or broken, it immediately sends a wire breakage signal to the adaptive controller.

[0044] Upon receiving a wire breakage signal, the adaptive controller immediately initiates emergency handling: First, it brakes the wire feeding servo motor of the wire feeding reel 140 and the take-up servo motor of the take-up reel 120 to stop the wire from moving. Second, it extends all the miniature electromagnetic guide rods 102 in the wire feeding assembly 150, causing the flexible abutment ball 101 to press the wire firmly and prevent it from springing back. Simultaneously, it depressurizes the horizontal cylinder 190 and vertical cylinder 130 of the straightening structure, disengaging the guide wheel from the wire and preventing the broken end from jamming. After the operator completes the wiring process, the adaptive controller resets all mechanisms.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
