Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical guidewire manufacturing technology, and in particular to a bend forming machine. Background Technology
[0002] The existing guide wire bend forming process involves first welding the guide wire core and spring together, and then bending the guide wire body formed by the guide wire core and spring. Usually, the guide wire body is bent manually by workers using equipment. However, this method has a large error and is not conducive to the rapid production of guide wires. Therefore, there is an urgent need for a bend forming equipment that can quickly bend the guide wire body. Utility Model Content
[0003] The purpose of this utility model is to provide a bend forming machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] An elbow forming machine includes:
[0006] frame;
[0007] A feeding mechanism includes a pushing assembly, the pushing assembly including a pushing part and a material transfer clamping part, the material transfer clamping part being mounted on the pushing part;
[0008] The bending forming mechanism includes a turntable, a winding post, and a fixed clamp. The turntable is rotatably mounted on the frame. The winding post is mounted on the turntable and located at the pivot position of the turntable. The fixed clamp is mounted on the turntable and located at the outer periphery of the turntable. A clamping gap is formed in the fixed clamp. The pushing part can move and be positioned on the frame in a direction close to or away from the turntable. The material transfer clamping part can move to the input end position of the clamping gap.
[0009] This technical solution has at least the following beneficial effects: After the inner core and spring are welded together to form the guide wire body, the guide wire body is placed in the material transfer clamping part. At this time, the material transfer clamping part forms a fixed clamping on the guide wire body. Then, the pushing part moves towards the turntable, so that the material transfer clamping part can move to the clamping gap input end. At this time, the guide wire body extends into the clamping gap of the fixed jaw after passing the winding column and is clamped by the fixed jaw. Subsequently, the turntable rotates, driving the fixed jaw to rotate, so that the guide wire body can bend along the winding column to form an elastic bend. Then, the turntable drives the fixed jaw to perform a reset rotation. During the reset rotation, the fixed jaw pries open the bend. After the reset is completed, the pushing part drives the material transfer clamping part to move away from the turntable, and the material transfer clamping part drives the guide wire body to move away from the fixed jaw, so that the winding column can disengage from the gap between the end of the bend and the guide wire body, completing the separation of the guide wire body from the winding column, that is, completing the bend forming of the guide wire body.
[0010] The above solution has several advantages. First, by first fixing the inner core of the guide wire and the spring by welding them together, and then bending the guide wire body as a whole, it is easier to carry out the preceding process quickly compared to bending the inner core of the guide wire first and then welding the spring to the inner core of the guide wire. Second, this equipment can increase the bending speed of the guide wire body, realize the automated manufacturing of the guide wire body bend, reduce manual operation, and increase production speed.
[0011] As a further improvement to the above technical solution, the winding post includes a large-diameter section, a small-diameter section, and a connecting section arranged sequentially from top to bottom. The connecting section is connected to the turntable, and the height of the clamping gap is located between the maximum height and the minimum height of the small-diameter section.
[0012] By adopting the above technical solution, during the process of the guide wire body rotating around the winding post, firstly, the large-diameter part and the connecting part respectively limit the guide wire body at the small-diameter part from both sides, thereby preventing the guide wire body from detaching from the winding post during the bending process and causing equipment failure. Secondly, the small diameter at the small-diameter part allows the small-diameter part to detach from the small gap between the end of the bend head and the guide wire body when the bending forming machine completes the bending process normally, thereby achieving effective separation between the winding post and the guide wire body.
[0013] As a further improvement to the above technical solution, the turntable is provided with a guide claw on the side of the winding post away from the fixed claw, and a guide channel is formed in the guide claw. The guide channel and the clamping gap extend in the same horizontal straight line direction.
[0014] Because the guide wire body has a large length, the wobbling of the end of the guide wire body during movement may make it difficult for the guide wire body to enter the fixed channel. With the above technical solution, when the pushing part drives the guide wire body to move through the material transfer clamping part, it first enters the guide channel. At this time, the guide channel and the material transfer clamping part stabilize the end and middle section of the guide wire body respectively, so that the guide wire body is stable on the straight line of the extension direction of the clamping gap, thus smoothly entering the clamping gap.
[0015] As a further improvement to the above technical solution, the guide gripper includes two guide portions, which can move in a vertical direction toward each other or away from each other, forming a guide channel between the two guide portions, and the sidewalls of the two guide portions that are close to each other gradually move closer to each other from away from to close to the fixed gripper.
[0016] Through the above technical solution, sidewalls that gradually approach each other are set on the guide section to form a gradually narrowing guide channel, which provides good guidance for the guide wire body to accurately enter the guide channel and lays a good foundation for the guide wire body to stably enter the fixed channel.
[0017] As a further improvement to the above technical solution, both the guide gripper and the fixed gripper can move horizontally and perpendicularly to the first direction on the turntable.
[0018] Through the above technical solution, after moving the guide jaws and fixing the jaws, the guide channel and the clamping gap can be better aligned with each other, so that they extend in the same direction, which facilitates the movement of the guide wire body between the guide channel and the clamping gap. At the same time, after the guide jaws and fixing jaws move relative to the winding post, the straight line where the guide channel and the clamping gap are located is closer to the winding post, making the bend head formed by the guide wire body more precise.
[0019] As a further improvement to the above technical solution, the feeding mechanism further includes a storage trough and a transfer gripper. The storage trough is installed on the frame and located on one side of the pushing part along the first direction. The transfer gripper is capable of moving between the storage trough and the transfer clamping part.
[0020] By adopting the above technical solution, a storage trough is set on the frame to store multiple guide wire bodies. During the bending process, the transfer gripper is used to pick up the guide wire body, which is welded and fixed by the spring and the inner core of the guide wire, from the storage trough and place it on the transfer clamping part. This solution can reduce the workload of workers placing the guide wire bodies on the transfer clamping part. Multiple guide wire bodies can be placed directly on the storage trough, which improves the automation level when the guide wire body forms the bend. Moreover, because the automated bending forming machine can form the bend of the guide wire body on time and in quantity, it is only necessary to add raw materials to the storage trough on time and in quantity afterward.
[0021] As a further improvement to the above technical solution, the frame is provided with a vacuum suction component above the storage tank. The vacuum suction component has a vacuum suction head, which can move and be positioned in the vertical direction along the direction of approaching or moving away from the storage tank. The transfer gripper can move between the vacuum suction head and the material transfer clamping part.
[0022] Because the guide wire body has a small diameter, the transfer gripper may have difficulty gripping the guide wire body in the storage tank or may grip too much at once. By adopting the above technical solution, the cross-sectional area of the end of the vacuum suction head is adapted to the cross-sectional area of the guide wire body. In this way, the vacuum suction head can accurately pick up the guide wire body from the storage tank. After the vacuum suction head is lifted, it drives the guide wire body away from the storage tank. At this time, the transfer gripper grips the guide wire body from the vacuum suction head. This method avoids the situation where the transfer gripper grips too much guide wire body at once, which would cause the bending head forming mechanism to malfunction. It also avoids the situation where the transfer gripper has difficulty gripping a single guide wire body.
[0023] As a further improvement to the above technical solution, a discharge mechanism is also included. The discharge mechanism includes a finished product trough and a discharge gripper. The finished product trough is installed on the frame and located on the other side of the feeding mechanism along the first direction. The discharge gripper can move and be positioned between the finished product trough and the material transfer clamping part.
[0024] After the elbow forming process is completed, the pushing part drives the guide wire body to reset through the material transfer clamping part. At this time, the discharge gripper can grab the section of the guide wire body that protrudes from the material transfer clamping part, thereby transferring the guide wire body from the material transfer clamping part to the finished product tank for placement. This solution improves the process flow of the guide wire elbow forming process, realizes the fully automated operation of the guide wire body from feeding, elbow forming to discharge, further reduces the degree of manual involvement and the workload of workers, reduces product quality problems caused by human operation errors, and improves the product qualification rate and the rate of high-quality products.
[0025] As a further improvement to the above technical solution, the material transfer clamping part is provided with a pushing and stabilizing groove at one end near the turntable, and the bottom of the pushing and stabilizing groove is at the same horizontal height as the clamping gap.
[0026] By pushing the stabilizing groove, the guide wire body is further supported, reducing the risk of the end of the guide wire body near the turntable shaking during the process of being pushed by the material transfer clamping part. In addition, the pushing stabilizing groove can work together with the guide claw and the material transfer clamping part to further improve the stability of the guide wire body when it enters the fixed claw.
[0027] As a further improvement to the above technical solution, a hot air gun is provided on the frame, and the output end of the hot air gun can be moved to face the small diameter section.
[0028] With the above technical solution, when the turntable rotates and causes the guide wire body to bend to form a bend, the hot air gun blows hot air at the small diameter part, thereby heating and shaping the guide wire body that is bent at the small diameter part, so that the bend can be stably formed.

[0042] In the manufacturing process of medical guidewires, it is sometimes necessary to bend the end of the guidewire to form a bent head. Specifically, the existing manufacturing process is to first bend the end of the guidewire core to form the bent head, and then put a spring for imaging on the guidewire core and weld the end of the spring and the end of the bent head together. During this process, the spring will slip on the bent guidewire core, making it difficult to weld and fix. In order to reduce the difficulty of guidewire manufacturing, the existing process is improved by first welding and fixing the spring to the straight guidewire core, and then bending the fixed guidewire. However, manual bending makes it difficult to control the bending angle of the guidewire, which is difficult to meet the high precision requirements of the guidewire.
[0043] Reference Figure 1 and Figure 2 The elbow forming machine includes a frame 1, on which a feeding mechanism 2, an elbow forming mechanism 3, and a discharging mechanism 4 are provided. The guide wire body 5, which has been welded with a spring, is placed in the feeding mechanism 2 and pushed to the elbow forming mechanism 3 for bending at the end to form an elbow head 6. Then the guide wire body 5 is returned to the elbow forming mechanism 3 and the formed guide wire body 5 is sent out through the discharging mechanism 4.
[0044] Reference Figure 2 and Figure 3 The feeding mechanism 2 includes a pushing assembly, which includes a pushing part 21 and a material transfer clamping part 22. The material transfer clamping part 22 is mounted on the pushing part 21. (Refer to...) Figure 4 The bending forming mechanism 3 includes a turntable 31, a winding post 32, and a fixed clamp 33. The turntable 31 is rotatably mounted on the frame 1. The winding post 32 is mounted on the turntable 31 and located at the pivot position of the turntable 31. The fixed clamp 33 is mounted on the turntable 31 and located at the outer periphery of the turntable 31. A clamping gap is formed in the fixed clamp 33. The pushing part 21 can move and be positioned on the frame 1 in the direction close to or away from the turntable 31. The material transfer clamping part 22 can move to the input end position of the clamping gap.
[0045] Specifically, the pushing assembly also includes a drive threaded rod and a drive motor. With the moving direction of the pushing part 21 as the first direction, the drive threaded rod is rotatably mounted on the frame 1 and extends along the first direction. The drive motor is fixedly mounted on the frame 1 and its output end is connected to the drive threaded rod. The pushing part 21 is slidably mounted on the frame 1 and threadedly connected to the drive threaded rod. With this design, when the drive threaded rod rotates, the pushing part 21 can move on the frame 1. The material transfer clamping part 22 is mounted on the pushing block and can clamp the guide wire body 5, thereby stably pushing or pulling the guide wire body 5 under the drive of the pushing block.
[0046] The fixed clamp 33 includes two fixed clamping blocks 331 arranged sequentially in the vertical direction. The two fixed clamping blocks 331 can move in the direction of approaching or moving away from each other, forming a clamping gap between them. The two fixed clamping blocks 331 can move to be completely pressed together, thus completely fixing the guide wire body 5. The two fixed clamping blocks 331 can be driven by a bidirectional screw drive assembly or a cylinder drive assembly. In this embodiment, no specific limitation is made.
[0047] Reference Figure 5 and Figure 6As described above, after the welding of the inner core and spring is completed to form the guide wire body 5, the guide wire body 5 is placed in the transfer clamping part 22. At this time, the transfer clamping part 22 forms a fixed clamping of the guide wire body 5. Then, the pushing part 21 moves towards the turntable 31, so that the transfer clamping part 22 can move to the clamping gap input end. At this time, the guide wire body 5 extends into the clamping gap of the fixed clamp 33 after passing the winding post 32 and is clamped by the fixed clamp 33. Subsequently, the turntable 31 rotates, driving the fixed clamp 33 to rotate, so that the guide wire body 5 can move along the winding post 32. The wire post 32 rotates and bends to form an elastic bend head 6. Then, the turntable 31 drives the fixed clamp 33 to rotate and reset. During the reset rotation, the fixed clamp 33 pries open the bend head 6. After the reset is completed, the pushing part 21 drives the material transfer clamping part 22 to move away from the turntable 31. The material transfer clamping part 22 drives the guide wire body 5 to move away from the fixed clamp 33, so that the winding post 32 can be disengaged from the gap between the end of the bend head 6 and the guide wire body 5, thus completing the separation of the guide wire body 5 from the winding post 32, that is, completing the bend formation of the guide wire body 5.
[0048] Reference Figure 4 The winding post 32 includes a large diameter part 321, a small diameter part 322 and a connecting part arranged sequentially from top to bottom. The connecting part is connected to the turntable 31, and the height of the clamping gap is between the maximum height and the minimum height of the small diameter part 322.
[0049] As can be seen from the above, when the guide wire body 5 passes through the winding post 32 from the material transfer clamping part 22 and extends to the clamping gap, it enters the clamping gap after passing through the small diameter part 322. When the guide wire body 5 is bent around the winding post 32, the guide wire body 5 is also wound around the small diameter part 322. That is, the large diameter part 321 and the connecting part limit the guide wire body 5 at the small diameter part 322 from both sides, thereby preventing the guide wire body 5 from detaching from the winding post 32 during the bending process, which would cause the equipment to fail. Secondly, since the winding post 32 needs to be disengaged from the gap between the guide wire body 5 and the end of the bend head 6, the smaller the diameter of the winding post 32 in this part, the easier it is to disengage, reducing the jamming between the guide wire body 5 and the winding post 32 when separating.
[0050] The turntable 31 has a guide jaw 34 at the end of the winding post 32 away from the fixed jaw 33. A guide channel is formed in the guide jaw 34. The guide channel and the clamping gap extend in the same horizontal straight line direction. Specifically, the guide jaw 34 includes two guide parts 341. The two guide parts 341 can move in the vertical direction toward each other or away from each other. A guide channel is formed between the two guide parts 341. The side walls of the two guide parts 341 that are close to each other gradually move closer to each other from away from to close to the fixed jaw 33.
[0051] In this embodiment, the two guide parts 341 move relatively closer or relatively farther apart through a bidirectional threaded rod motor drive assembly or a cylinder drive assembly. In this embodiment, the drive structure is not specifically limited. A guide channel with a circular cross-section is always formed between the two guide parts 341, that is, the two guide parts 341 cannot be completely fitted together, and the guide channel always exists. After the guide wire body 5 passes through the winding post 32 and reaches the clamping gap, the two guide parts 341 move away from each other and finally fully open the guide gap. When the turntable 31 rotates, the guide wire body 5 can pass through the two guide parts 341 and abut against the small diameter part 322, thereby avoiding the location of the bent rotating shaft becoming the location of the guide claw 34.
[0052] Because the guide wire body 5 has a large length, the wobbling of the end of the guide wire body 5 during movement may make it difficult for the guide wire body 5 to enter the fixed channel. With the above technical solution, when the pushing part 21 moves the guide wire body 5 through the material transfer clamping part 22, it first enters the guide channel. At this time, the guide channel and the material transfer clamping part 22 stabilize the end and middle section of the guide wire body 5 respectively, so that the guide wire body 5 is stable on the straight line of the extension direction of the clamping gap, thus smoothly entering the clamping gap.
[0053] In a further embodiment, the sidewalls of the two guide portions 341 gradually approach each other from the direction away from the fixed gripper 33, forming a guide surface for the guide wire body 5, so that the guide wire body 5 can smoothly reach the guide channel after passing through these sidewalls.
[0054] Reference Figure 2 and Figure 4 Both the guide jaw 34 and the fixed jaw 33 can move on the turntable 31 in a horizontal direction perpendicular to the first direction or in a vertical direction. The movement of the guide jaw 34 and the fixed jaw 33 in three dimensions allows the guide channel and the clamping gap to be better aligned with each other. It also makes it easier for workers to adjust the guide jaw 34 and the fixed jaw 33, so that the straight line where the guide channel and the clamping gap are located is closer to the winding post 32, making the bend head 6 formed by the guide wire body 5 more precise.
[0055] Specifically, the turntable 31 is equipped with three-dimensional fine-tuning platforms corresponding to the guide gripper 34 and the fixed gripper 33 respectively. The guide gripper 34 and the fixed gripper 33 are respectively installed on the corresponding three-dimensional fine-tuning platforms. When adjustment is required, simply tighten the bolts on the corresponding three-dimensional fine-tuning platforms.
[0056] Reference Figure 2 , Figure 5 and Figure 6The feeding mechanism 2 also includes a storage trough 23 and a transfer gripper 24. The storage trough 23 is installed on the frame 1 and located on one side of the pushing part 21 along the first direction. The transfer gripper 24 can move between the storage trough 23 and the transfer clamping part 22. Specifically, the storage trough 23 is a V-shaped groove. The storage trough 23 extends along the first direction and the tip of the storage trough 23 faces downward. The storage trough 23 is set on the frame 1 to store multiple guide wire bodies 5. When performing the bending forming process, the transfer gripper 24 is used to clamp the guide wire body 5, which is fixed by welding the spring and the guide wire core, from the storage trough 23 and place it on the transfer clamping part 22. This solution can reduce the workload of workers placing the guide wire body 5 on the transfer clamping part 22. Multiple guide wire bodies 5 can be placed directly on the storage trough 23, which improves the automation level when the guide wire body 5 forms a bend.
[0057] Specifically, the frame 1 is provided with a first transverse drive that moves horizontally perpendicular to the first direction. The first transverse drive can be a cylinder or a motor screw assembly. In this embodiment, the first transverse drive is a cylinder. The output end of the first transverse drive can move horizontally perpendicular to the first direction in the horizontal plane. A lifting cylinder is installed at the output end of the first transverse drive. The transfer gripper 24 is installed at the output end of the lifting cylinder. Through the combination of the first transverse drive and the lifting cylinder, the transfer gripper 24 can be driven to move in a two-dimensional direction, thereby gripping the guide wire body 5 at the storage groove 23 and placing it on the transfer clamping part 22.
[0058] Because the diameter of the guide wire body 5 is relatively small, the transfer gripper 24 may encounter difficulties in gripping the guide wire body 5 or may grip too much at once when it grasps it in the storage tank 23. (Refer to...) Figure 2 , Figure 5 and Figure 6 The frame 1 is equipped with a vacuum suction unit above the storage tank 23. The vacuum suction unit has a vacuum suction head 7, which can move and be positioned in the vertical direction along the direction of approaching or moving away from the storage tank 23. The transfer gripper 24 can move between the vacuum suction head 7 and the transfer clamping part 22.
[0059] Specifically, the vacuum suction component includes a vacuum generator, a vacuum suction head 7, and a lifting cylinder. The vacuum generator is fixedly mounted on the frame 1, and the lifting cylinder is also fixedly mounted on the frame 1. The output end of the lifting cylinder moves vertically. The vacuum suction head 7 is mounted on the output end of the lifting cylinder and is connected to the vacuum generator via an air pipe. The suction chamber width of the vacuum suction head 7 is adapted to the diameter of the guide wire body 5.
[0060] As can be seen from the above, the cross-sectional area of the end of the vacuum suction head 7 is adapted to the cross-sectional area of the guide wire body 5. In this way, the vacuum suction head 7 can accurately pick up the guide wire body 5 from the storage tank 23. Then, after the vacuum suction head 7 is lifted, it drives the guide wire body 5 to leave the storage tank 23. At this time, the transfer gripper 24 picks up the guide wire body 5 from the vacuum suction head 7. This method avoids the situation where the transfer gripper 24 picks up too many guide wire bodies 5 at one time, which would cause the bending head forming mechanism 3 to malfunction. It also avoids the situation where the transfer gripper 24 has difficulty picking up a single guide wire body 5.
[0061] Reference Figure 2 and Figure 6 The discharge mechanism 4 includes a finished product trough 41 and a discharge gripper 42. The finished product trough 41 is installed on the frame 1 and located on the other side of the feeding mechanism 2 along the first direction. The discharge gripper 42 can move and be positioned between the finished product trough 41 and the material transfer clamping part 22. After the bending head forming process is completed, the pushing part 21 drives the guide wire body 5 to reset through the material transfer clamping part 22. At this time, the discharge gripper 42 can grab the section of the guide wire body 5 that protrudes from the material transfer clamping part 22, thereby transferring the guide wire body 5 from the material transfer clamping part 22 to the finished product trough 41 for placement. This solution improves the process of the guide wire bending head forming process and realizes the fully automated operation of the guide wire body 5 from feeding, bending head forming to discharge.
[0062] Specifically, the frame 1 is provided with a second transverse drive that moves horizontally perpendicular to the first direction. The second transverse drive is located on the other side of the first transverse drive that is opposite to the material transfer clamping block. The second transverse drive can be a cylinder or a motor screw assembly. In this embodiment, the second transverse drive is a cylinder. The output end of the second transverse drive can move horizontally perpendicular to the first direction in the horizontal plane. A lifting cylinder is installed at the output end of the second transverse drive. The discharge clamp 42 is installed at the output end of the lifting cylinder. Through the combination of the second transverse drive and the lifting cylinder, the discharge clamp 42 can be driven to move in a two-dimensional direction, thereby clamping the guide wire body 5 at the material transfer clamping part 22 and placing it on the finished product trough 41.
[0063] Reference Figure 3 , Figure 5 and Figure 6 The material transfer clamping part 22 is provided with a push stabilizing groove 25 at one end near the turntable 31. The bottom of the push stabilizing groove 25 is at the same horizontal height as the clamping gap.
[0064] By pushing the stabilizing groove 25, the guide wire body 5 is further supported, reducing the risk of the end of the guide wire body 5 near the turntable 31 shaking during the push of the material transfer clamping part 22. In addition, the pushing stabilizing groove 25 can work together with the guide claw 34 and the material transfer clamping part 22 to further improve the stability of the guide wire body 5 when it enters the fixed claw 33.
[0065] Reference Figure 5 and Figure 6 A hot air gun 8 is installed on the frame 1. The output end of the hot air gun 8 can be moved to face the small diameter section 322. When the turntable 31 rotates and drives the guide wire body 5 to bend to form the bent head 6, the hot air gun 8 blows hot air at the small diameter section 322, thereby heating and shaping the guide wire body 5 bent at the small diameter section 322, so that the bent head 6 can be stably formed.
