Description

Technical Field

[0001] This invention relates to the field of bending machine technology, specifically to a continuous bending machine for alloy wire with real-time monitoring of bending force. Background Technology

[0002] Alloy wires are widely used in electronic components, electrical equipment and other fields due to their excellent electrical conductivity, thermal conductivity, corrosion resistance and mechanical properties.

[0003] In many applications, alloy wires need to be bent to form specific spatial shapes to meet product assembly and functional requirements.

[0004] Currently, alloy wire bending is mainly done manually using dies or automatically by machines. The advantages of manual bending are low cost, ensuring that the bending angle and curvature will not spring back, and quick correction of defects. The disadvantage is low efficiency.

[0005] The advantage of automated bending of alloy wire by machines is that the bending efficiency far exceeds that of manual bending, enabling mass production at high speed. The disadvantage is that existing equipment generally uses stroke control or angle control to perform the bending action, that is, driving the bending actuator according to a preset displacement or rotation angle, without monitoring the actual bending force on the alloy wire during the bending process. Because different batches of alloy wire have objective differences in hardness, tensile strength, and residual stress, the actual bending effect produced by the same stroke or angle parameters under different material conditions is inconsistent. Some harder alloy wires may spring back after reaching the bending angle if the die is released quickly, making it difficult to guarantee the consistency of product bending accuracy.

[0006] To address this, a continuous bending machine for alloy wire with real-time monitoring of bending force is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a continuous bending machine for alloy wire with real-time monitoring of bending force, so as to solve the problem of inconsistent bending accuracy of bending machines mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A continuous bending machine for alloy wire with real-time bending force monitoring includes a frame. From right to left, the frame is arranged a straightening roller assembly for straightening the alloy wire, a conveying assembly for conveying the alloy wire, a cutting assembly for cutting the alloy wire, and a bending assembly for bending the alloy wire. The conveying assembly includes multiple conveying wheels evenly arranged horizontally on the frame, with a conveying motor below each wheel for controlling its rotation. The cutting assembly includes a guide channel and a cutting blade disposed on the frame. The guide channel is located near the conveying wheels and is positioned below the cutting blade. Directly in front, the cutting blade is located on the side near the bending assembly. The bending assembly includes a bending ring and a fixing plate mounted on the frame. A bending block is mounted on the bending ring. A rotary cylinder for rotating the bending ring is located below the bending ring. A first telescopic cylinder for moving the rotary cylinder up and down is located below the rotary cylinder. The fixing plate is located in the middle of the bending ring. A chuck for fixing the alloy wire during bending is mounted on the fixing plate. A second telescopic cylinder for moving the chuck up and down is located below the frame. A torque sensor is also mounted between the rotary cylinder and the bending ring.

[0009] By setting a torque sensor to collect bending torque data in real time during the bending process, the control system can automatically determine the actual yield state of the alloy wire according to the torque change law. When the torque reaches the preset threshold, the bending mechanism is controlled to maintain the current bending angle for a period of time before being released, which can effectively offset the springback of the alloy wire after bending, thereby improving the consistency of the bending angle.

[0010] By installing a torque sensor in the bending drive mechanism, the bending force can be collected and fed back in real time during the bending process. This enables the mechanism to adapt to the fluctuations in the properties of different batches of alloy wire materials, which helps to automatically adjust the bending pressure holding strategy and solves the problem of unstable bending accuracy caused by material strength differences in the traditional fixed-stroke bending method.

[0011] Preferably, the frame is further provided with a crossbeam, and an electric push rod is provided on the crossbeam. The output end of the electric push rod is positioned downward and directly above the chuck. A mounting block is positioned downward at the output end of the electric push rod, and a pressing rod is provided below the mounting block to prevent the alloy wire from jumping upward during bending.

[0012] By setting a pressing rod to limit the top of the alloy wire, the upward component force applied by the bending block to the alloy wire during the bending process is counteracted, preventing the alloy wire from warping and jumping under the bending force, ensuring the stability of the alloy wire position during the bending process, and further improving the bending accuracy.

[0013] Preferably, the jaw includes a first clamping part fixedly disposed on one side of the top surface of the fixed disk, a groove is formed on the top surface of the fixed disk opposite to the first clamping part, a slider is slidably installed inside the groove, a second clamping part corresponding to the first clamping part is provided on the top of the slider, a return spring is also provided inside the groove, the return spring is used to push the slider away from the first clamping part, a downwardly inclined guide ramp is provided on the top of the second clamping part, a pressing groove is formed at the bottom of the mounting block, a pressing ramp matching the guide ramp is provided on one side of the pressing groove, and a pressure sensor is also provided on the second clamping part for detecting the pressure between the second clamping part and the alloy wire.

[0014] By setting up a pressure sensor to detect the pressure of the second clamping part, the control system can monitor the clamping status in real time, ensuring that the first and second clamping parts remain stably in contact with the alloy wire throughout the entire bending process of the alloy wire. This avoids the alloy wire shifting due to insufficient clamping force and further improves the bending accuracy of the alloy wire during bending.

[0015] Preferably, the side of the first clamping part away from the second clamping part is a support surface, the support surface is perpendicular to the top surface of the fixed plate, and the side of the pressing groove away from the pressing slope is provided with a mating surface that cooperates with the support surface. When the mounting block moves downward, the mating surface is mated with the support surface.

[0016] Since the second clamping part is movable, the bending reaction force borne by the second clamping part will be applied to the mounting block during the bending process. The mounting block is connected to the electric push rod, and the electric push rod is easily damaged because it directly bears the force perpendicular to the output direction.

[0017] By setting mutually cooperating support surfaces and contact surfaces, the lateral reaction force acting on the second clamping part during bending can be transferred to the fixed first clamping part to bear, avoiding the lateral force acting directly on the output rod of the electric push rod. This not only prevents the electric push rod from being damaged due to bearing an off-center load perpendicular to the output direction, thus extending the service life of the equipment, but also ensures that the second clamping part will not slip when subjected to bending force, further improving the stability of the clamping and fixing of the jaws.

[0018] Preferably, the mounting block has a vertically formed telescopic groove, the pressing rod is slidably installed inside the telescopic groove, and a push spring is provided inside the telescopic groove to keep the pressing rod pushed downward.

[0019] By setting up a retractable pressing rod structure, the pressing rod can automatically adapt to alloy wires of different heights and specifications. This not only avoids structural interference between the fixed-length pressing rod and the top of the alloy wire, ensuring the safe operation of the equipment, but also ensures that the pressing rod always applies a stable limiting pressure to the top of the alloy wire. This further enhances the equipment's adaptability to bending alloy wires of different specifications, ensuring processing stability and bending accuracy.

[0020] Preferably, the mounting block is made of a non-magnetic metal material, and a mounting groove is provided inside the mounting block. The mounting groove is connected to the telescopic groove. The pressing rod is made of a magnetic metal material, and an electromagnet is horizontally installed inside the mounting groove. One end face of the electromagnet is in contact with the side wall of the pressing rod, and the electromagnet is electrically connected to the pressure sensor.

[0021] By setting up an electromagnet, when the pressure sensor detects that the second clamping part has completed clamping the alloy wire, it can trigger the electromagnet to be energized and attract the pressing rod. The pressing rod is locked in its extension and retraction position by magnetic force, which prevents the pressing rod from retracting upwards to its original position due to the reaction force during the bending process. This further ensures the stable pressing of the pressing rod on the top of the alloy wire, avoids the alloy wire from bending and jumping upwards during the bending process, and improves the positional stability of the alloy wire during the bending process.

[0022] Preferably, two first rotating columns are rotatably mounted on the first clamping part, and the first rotating columns are spaced apart along the conveying direction of the alloy wire. Two second rotating columns are provided on the second clamping part, and the two second rotating columns are spaced apart along the conveying direction of the alloy wire. The pressure sensor is disposed between the second rotating columns and the second clamping part.

[0023] By setting rotatable first and second rotating columns, the sliding friction between the alloy wire and the clamping part during continuous feeding is converted into rolling friction, which effectively reduces the frictional resistance of the alloy wire during feeding. This ensures that the alloy wire can still be stably fed forward while the chuck is in a clamping limit state, without the need to repeatedly loosen and re-clamp the chuck. This simplifies the bending process and improves the production efficiency of continuous bending.

[0024] Preferably, one of the second rotating posts away from the cutter is aligned with one of the first rotating posts away from the cutter. A detection groove is horizontally formed on the second clamping part, and the detection groove is positioned towards the first clamping part and located between the two first rotating posts. The second rotating post closer to the cutter is vertically rotatably mounted inside the detection groove and can slide along the direction of the detection groove inside the detection groove. The pressure sensor is located inside the detection groove, and a retaining spring is provided inside the detection groove. One end of the retaining spring abuts against the second rotating post, and the other end abuts against the pressure sensor. The retaining spring is used to keep the second rotating post inside the detection groove pushed towards the first clamping part. When the second rotating post inside the detection groove is at its extreme position away from the pressure sensor, the minimum distance from the second rotating post inside the detection groove to the first clamping part is less than the minimum distance from the other second rotating post to the first clamping part.

[0025] By setting a movable second rotating column in conjunction with a retaining spring and a pressure sensor, the pressure sensor can be triggered to output a detection signal immediately after the alloy wire enters the clamping position through the retraction displacement of the movable second rotating column. This allows the control system to quickly confirm that the alloy wire is in place and adjust the clamping force. This ensures the response speed of pressure detection and uses the retaining spring to buffer the instantaneous force transmitted from the second rotating column to the pressure sensor. At the same time, the wear generated by the rotation of the second rotating column exists only on its own shaft structure and the detection spring, and does not directly act on the detection end of the pressure sensor. This can effectively extend the service life of the pressure sensor, ensure the long-term stability of pressure detection, and reduce the cost of replacement and maintenance of the equipment in the later stages.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The alloy wire continuous bending machine with real-time bending force monitoring designed in this invention realizes real-time acquisition and feedback of bending force during the bending process by adding a torque sensor to the bending drive mechanism. It can adapt to the fluctuation of mechanical properties of different batches of alloy wires, help the control system automatically adjust the bending pressure, effectively solve the problem of unstable bending accuracy caused by material strength differences in traditional fixed stroke and fixed angle bending methods, and effectively improve the consistency of bending angle and the finished product qualification rate.

[0027] 2. The alloy wire continuous bending machine with real-time bending force monitoring designed in this invention converts the sliding friction between the alloy wire and the clamping part during feeding into rolling friction by setting a rotating column in the clamping part of the jaws. While ensuring that the jaws remain in the clamping limit state, the alloy wire can still be stably fed forward, eliminating the need for repeated loosening and tightening of the jaws, simplifying the operation process of continuous bending processing, and effectively improving the production efficiency of continuous processing. At the same time, by setting a movable detection rotating column in conjunction with a pressure sensor, the arrival status of the alloy wire is quickly detected, and the wear of rotation can be avoided from affecting the detection accuracy and service life of the pressure sensor, further improving the stability of equipment operation.

[0028] 3. The alloy wire continuous bending machine with real-time bending force monitoring designed in this invention limits the top of the alloy wire by setting a pressing rod, and in conjunction with a telescopic structure and an electromagnet locking mechanism, it cancels the upward component force applied to the alloy wire by the bending block during the bending process, avoids the alloy wire from warping and jumping under the bending force, and ensures the stability of the alloy wire position during the bending process.

The conveying assembly 3 includes multiple conveying wheels 301 evenly arranged horizontally on the frame 1. Each conveying wheel 301 has a conveying motor 302 below it for controlling its rotation. A dust cover 24 for protecting the conveying wheels 301 from dust is also rotatably mounted on the frame 1.

[0032] refer to Figure 1 The cutting assembly 4 includes a guide channel 401 and a cutting blade 402 disposed on the frame 1. The guide channel 401 is located on the side close to the conveyor wheel 301 and is located directly in front of the cutting blade 402. The cutting blade 402 is located on the side close to the bending assembly 5.

[0033] refer to Figures 1 to 5The bending assembly 5 includes a bending ring 501 and a fixed plate 502 mounted on the frame 1. The fixed plate 502 is circular, and the bending ring 501 is coaxially sleeved on the fixed plate 502. A bending block 503 is mounted on the bending ring 501. A rotary cylinder 504 for rotating the bending ring 501 is located below the bending ring 501. A first telescopic cylinder 505 for moving the rotary cylinder 504 up and down is located below the rotary cylinder 504. The fixed plate 502 is located in the middle of the bending ring 501 and has a chuck 6 for fixing the alloy wire during bending. A second telescopic cylinder 506 for moving the chuck 6 up and down is located below the frame 1. A torque sensor 507 is also located between the rotary cylinder 504 and the bending ring 501. The rotary cylinder 504 is a cylinder with a central through-hole to facilitate the passage of the second telescopic cylinder 506 through it.

[0034] In addition, refer to Figure 1 and Figure 5 The frame 1 is also equipped with a crossbeam 7, and an electric push rod 8 is mounted on the crossbeam 7. The output end of the electric push rod 8 is set downward and is located directly above the claw 6. The output end of the electric push rod 8 is set downward with a mounting block 9. The mounting block 9 is made of non-magnetic metal material. A pressing groove 11 is opened at the bottom of the mounting block 9. A telescopic groove 16 is also vertically opened on the mounting block 9. A pressing rod 10 is slidably mounted inside the telescopic groove 16. A push spring 17 is set inside the telescopic groove 16. The push spring 17 is used to keep the pressing rod 10 pushed downward and extended into the pressing groove 11.

[0035] Further reference Figure 5 The mounting block 9 has a horizontally opened mounting groove 18 inside, which is connected to the telescopic groove 16. The pressing rod 10 is made of magnetic metal material. An electromagnet 19 is horizontally installed inside the mounting groove 18. One end face of the electromagnet 19 is attached to the side wall of the pressing rod 10. The electromagnet 19 is electrically connected to the pressure sensor 13.

[0036] In addition, refer to Figures 5 to 7 The chuck 6 includes a first clamping part 601 fixedly disposed on one side of the top surface of the fixed disk 502. The side of the first clamping part 601 away from the second clamping part 604 is a support surface 14, which is perpendicular to the top surface of the fixed disk 502. Two first rotating columns 20 are rotatably mounted on the first clamping part 601, and the first rotating columns 20 are spaced apart along the conveying direction of the alloy wire. The side of the pressing groove 11 away from the pressing ramp 12 is also provided with a contact surface 15 that mates with the support surface 14. When the mounting block 9 moves downward, the contact surface 15 contacts the support surface 14.

[0037] refer to Figure 6A groove 602 is provided on the top surface of the fixed plate 502 on the side opposite to the first clamping part 601. A slider 603 is slidably installed inside the groove 602. A second clamping part 604 corresponding to the first clamping part 601 is provided on the top of the slider 603. A return spring 605 is also provided inside the groove 602. The return spring 605 is used to push the slider 603 away from the first clamping part 601.

[0038] refer to Figures 5 to 7 The second clamping part 604 is also provided with two second rotating posts 21, which are spaced apart along the conveying direction of the alloy wire. One of the second rotating posts 21, farther from the cutter, is aligned with a first rotating post 20, also farther from the cutter, and is rotatably mounted on the second clamping part 604. A detection groove 22 is horizontally formed on the second clamping part 604, facing the first clamping part 601, and located between the two first rotating posts 20. A second rotating post 21, closer to the cutter, is vertically rotatably mounted inside the detection groove 22 and can slide along the direction of the detection groove 22. A pressure sensor 13 is fixedly mounted inside the detection groove 22 on the side farther from the first clamping part 601. The pressure sensor 13 is used to detect the pressure between the second clamping part 604 and the alloy wire. Furthermore, a retaining spring 23 is provided inside the detection groove 22. One end of the retaining spring 23 abuts against the second rotating column 21, and the other end abuts against the pressure sensor 13. The retaining spring 23 is used to keep the second rotating column 21 inside the detection groove 22 pushed towards the first clamping part 601.

[0039] When the second rotating column 21 located inside the detection groove 22 is at its extreme position farthest from the pressure sensor 13, the minimum distance from the second rotating column 21 inside the detection groove 22 to the first clamping part 601 is less than the minimum distance from the other second rotating column 21 to the first clamping part 601. Figure 7 The intermediate distance L is less than the distance H.

[0040] In addition, refer to Figure 4 The top of the second clamping part 604 is provided with a downwardly inclined guide ramp 606, and a pressing ramp 12 matching the guide ramp 606 is provided on one side of the pressing groove 11.

[0041] Working principle: refer to Figures 1 to 8In the initial state, the second telescopic cylinder 506 remains extended upwards, and the fixed plate 502 is flush with the top surface of the frame 1. After the equipment is started, the alloy wire to be processed is first passed through the guide channel 401 of the straightening roller group 2, the conveying component 3, and the cutting component 4 in sequence, and the end of the alloy wire is sent to the position of the chuck 6 of the bending component 5; then the electric push rod 8 drives the mounting block 9 to move downwards, and the pressing ramp 12 at the bottom of the mounting block 9 presses the guide ramp 606 of the second clamping part 604, causing the second clamping part 604 to slide along the slide groove 602 towards the first clamping part 601, thus completing the pre-clamping of the alloy wire.

[0042] In this process, refer to Figure 4 As the mounting block 9 moves downward, the pressing rod 10 on the mounting block 9 will abut against the top of the alloy wire, and as the mounting block 9 continues to move downward, the pressing rod 10 will be squeezed and retracted into the telescopic groove 16.

[0043] As mounting block 9 continues to move, reference Figure 4 and Figure 5 The second rotating column 21, which is located inside the slide groove 602 and is movably positioned near the cutter, will first contact the side wall of the alloy wire and push the side wall of the alloy wire toward the first rotating column 20. When the alloy wire abuts against the first rotating column 20, as the second clamping part 604 continues to move, the second rotating column 21 located inside the slide groove 602 retracts along the detection groove 22 under the reaction force of the alloy wire, compresses the retaining spring 23 and triggers the pressure sensor 13 to output a clamping signal. When the pressure sensor 13 detects that the pressure has reached the set value, the control system receives the signal and confirms that the alloy wire is clamped in place.

[0044] Subsequently, reference Figure 5 The electrical signal from the pressure sensor 13 is also transmitted to the control system, which then triggers the electromagnet 19 to be energized, attracting and locking the extension position of the pressing rod 10, ensuring that the pressing rod 10 is stably pressed against the top of the alloy wire. The electromagnet 19 is designed to ensure that the pressing rod 10 can freely extend and retract according to the height of the alloy wire, and also to achieve rapid stepless locking of the pressing rod 10.

[0045] Then, refer to Figure 1 The conveying assembly 3 drives the conveying wheel 301 to rotate, conveying the alloy wire forward to the preset processing length. The rotary cylinder 504 drives the bending ring 501 to rotate, which in turn drives the bending block 503 to perform a bending action on the alloy wire. During the bending process, the torque sensor 507 collects bending torque data in real time and transmits it to the control system. The control system judges the actual yield state of the alloy wire according to the torque change law. When the torque reaches the preset threshold, the control system controls the bending ring 501 to maintain the current bending angle and hold the pressure for a set time before releasing it, thereby offsetting the springback of the alloy wire after bending.

[0046] After bending, refer to Figure 2 and Figure 4 The first telescopic cylinder 505 drives the bending ring 501 to move downwards to avoid the obstacle, while the second telescopic cylinder 506 drives the fixed plate 502 and the gripper to retract downwards to avoid the obstacle. The conveying motor 302 drives the conveying wheel 301 to rotate in the opposite direction, pulling the alloy wire back to the position of the cutting blade 402. The cutting blade 402 cuts off the processed alloy wire segment, and the alloy wire bending is completed to form the finished product. Subsequently, the first telescopic cylinder 505 and the second telescopic cylinder 506 reset, thus completing one complete processing cycle. Repeating the above actions can achieve continuous bending processing of the alloy wire.

[0047] Furthermore, during the processing, as the supporting surface 14 and the contact surface 15 cooperate with each other, the lateral reaction force acting on the second clamping part 604 during the bending process is transferred to the fixed first clamping part 601 to bear, avoiding the lateral force acting directly on the output rod of the electric push rod 8, preventing the electric push rod 8 from being damaged due to bearing an off-center load perpendicular to the output direction, extending the service life of the equipment, and ensuring that the second clamping part 604 will not slide when subjected to bending force, thus improving the stability of the clamping and fixing of the claw 6.

[0048] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
