Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tools, in particular to a guide wire bending machining tool. BACKGROUND

[0002] Metal guide wires are related to many fields such as medical treatment, electronics, and communication. As a connection and transmission element, the processing quality of the metal guide wire directly affects the use performance and safety. Existing guide wire processing technology uses automatic equipment to perform shaping operations on the guide wire to meet the needs of different scenarios. These devices stretch, bend, or cut the guide wire through mechanical structures to form guide wires of specific shapes. However, the existing technology generally has a technical problem in the guide wire processing process, that is, it is difficult to achieve high processing speed while ensuring guide wire processing precision.

[0003] When pursuing high precision, existing guide wire processing equipment often needs to reduce processing speed to avoid processing errors caused by inertia or vibration in high-speed motion. This low-speed processing method can ensure the shaping precision of the guide wire, but significantly prolongs the production cycle and reduces the production efficiency of the equipment, making it difficult to meet the needs of large-scale production. On the other hand, if processing speed is prioritized, the existing technology sacrifices processing precision. For example, by increasing the movement speed of mechanical parts or simplifying the processing steps, more guide wires can be shaped in a short time, but this easily leads to shape deviation or surface quality degradation of the guide wire, which cannot meet the high precision requirements of the medical field.

[0004] Therefore, there is an urgent need for a new technical solution that can significantly improve guide wire processing speed without sacrificing processing precision to solve this core technical problem in existing technology and promote the development of guide wire processing equipment to higher performance.

DETAILED DESCRIPTION

[0032] In order to make the purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] In the description of the present application, it needs to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there can be a component disposed therebetween.

[0034] The technical solutions of the present application will be further illustrated below in conjunction with the drawings and through specific embodiments.

[0035] In an embodiment, referring to Figures 1 to 6 A guide wire bending processing machine tool includes a rack 1; a feeding assembly 2 disposed on the rack 1, the feeding assembly 2 including a first driving member 21, a sliding track 22 and a guide frame 23, the guide frame 23 being used for placing a guide wire, the first driving member 21 being used for driving the guide frame 23 to reciprocate along the sliding track 22; a processing assembly 3 connected with the feeding assembly 2, the processing assembly 3 including a control motor 31, a rotating platform 32, a jaw assembly 33 and a circular rod 34, the jaw assembly 33 and the circular rod 34 being both disposed on the rotating platform 32, the jaw assembly 33 being used for clamping an end of the guide wire on the guide frame 23 away from the guide frame 23, the control motor 31 being used for driving the rotating platform 32 to drive the jaw assembly 33 to rotate the guide wire around the circular rod 34 to form a bent guide wire.

[0036] In the embodiment, the rack 1 is the basic component of the whole guide wire bending processing machine tool, including internal structure and external structure, the internal structure mainly contains the jacking assembly 5, etc., the feeding assembly 2 and the processing assembly 3 are arranged on the upper surface of the rack 1. The feeding assembly 2 is responsible for sending the guide wire to be processed into the processing area, the feeding assembly 2 is arranged on the rack 1, and is connected with the rack 1 through bolts or other fixing modes. The feeding assembly 2 is composed of a first driving member 21, a sliding rail 22 and a guide frame 23. The guide frame 23 is used for placing the guide wire to be processed, and adopts a groove or clamping structure, so that the guide wire can be fixed and positioned accurately in the frame. The material of the guide frame 23 can be selected from metal or engineering plastic which is wear-resistant and smooth in surface, so as to reduce the friction between the guide frame 23 and the guide wire and avoid scratching the surface of the guide wire. The sliding rail 22 can be a linear guide rail, and the first driving member 21 is the power source of the feeding assembly 2. A servo motor or a stepping motor can be adopted, which is connected with the guide frame 23 through a transmission mechanism such as a gear, a belt 41 or a lead screw, to drive the guide frame 23 to reciprocate along the sliding rail 22. This reciprocating movement enables the guide wire to be sent into the processing area at a stable pace, avoiding the position deviation or speed unevenness problem caused by manual feeding. The processing assembly 3 is directly connected with the feeding assembly 2, and is responsible for processing the sent guide wire into a finished product with a specific bending shape. The installation position of the processing assembly 3 is close to the output end of the feeding assembly 2, so that the position deviation is minimized when the guide wire is transferred from the guide frame 23 to the clamping mechanism of the processing assembly 3. The processing assembly 3 includes a control motor 31, a rotating platform 32, a jaw assembly 33 and a circular rod 34. The rotating platform 32 is a circular or polygonal platform structure, which is connected with the rack 1 through a bearing or other rotating support mechanism. The control motor 31 is the power source of the rotating platform 32, which can be selected from a high-precision servo motor, and is connected with the rotating platform 32 through a reducer or a direct driving mode, so as to control the rotation angle and speed of the rotating platform 32. The jaw assembly 33 and the circular rod 34 are both fixed on the rotating platform 32, and together constitute an execution mechanism for guide wire bending processing. The circular rod 34 is fixed on the platform through a support frame. The jaw assembly 33 is used for clamping the end of the guide wire away from the guide frame 23, and its clamping mechanism can be composed of a pneumatic or electrically driven jaw, which can adjust the clamping force according to the diameter and material of the guide wire, so that the guide wire will not slip or be damaged due to excessive clamping force during the processing. The clamping point of the jaw assembly 33 is located at the free end of the guide wire, which avoids the deformation of the guide wire caused by multi-point stress during the processing, and also facilitates the rotation and bending of the guide wire around the circular rod 34. The circular rod 34 is made of a high-hardness and wear-resistant metal material, and its surface is polished, so that the guide wire can smoothly fit the surface of the circular rod 34 during rotation, forming a uniform bending radius.When the motor 31 is controlled to drive the rotating platform 32 to rotate, the guide wire clamped by the jaw assembly 33 moves along with the rotating platform 32 around the circular rod 34, so as to form a desired bending shape (which can be 180° to form a hook-like bending shape) on the guide wire.

[0037] It is worth noting that the jaw assembly 33 includes two jaws, including a first jaw and a second jaw, which are respectively arranged on opposite sides of the circular rod 34, so that the guide wire can be kept stable during bending, and the distance between the two jaws can be adjusted according to the diameter of the guide wire, so that the clamping is stable and does not cause unnecessary damage to the guide wire. Specifically, the second jaw is connected to a telescopic cylinder, which can drive the second jaw to move along the direction of the circular rod 34, so as to adjust the distance between the two jaws. In another embodiment, the rotation angle of the motor 31 can be controlled by software, and the process radius of the guide wire can be arbitrarily bent. The motor 31 is equipped with an encoder, which can feedback the rotation angle of the rotating platform 32. The software control system adjusts the rotation angle and speed of the motor according to the preset processing parameters or the process requirements input by the user, so that the machine tool can flexibly cope with the processing requirements of guide wires of different specifications and shapes. Through parameter adjustment, the software control system can realize quick switching, thereby improving the versatility and production flexibility of the equipment. Through the optimized cooperation of the feeding assembly 2 and the processing assembly 3 and the regulation of the software control system on the processing process, the machine tool can realize unit hour output (UPH) ≥500 pieces / hour, while maintaining a product yield of ≥99.5%. For example, the feeding assembly 2 can send the guide wire into the processing area at a high frequency through the rapid reciprocating motion of the first driving member 21. The processing assembly 3 can complete the bending processing of the guide wire in a very short time through the high-speed rotation of the control motor 31 and the clamping of the jaw assembly 33, which can meet the demand of large-scale orders in a high-intensity production scenario, and the yield of ≥99.5% indicates that almost no waste is generated in the processing process. Compared with traditional guide wire processing equipment, the machine tool is designed to be automated and intelligent, which significantly reduces the need for manual intervention and reduces the defect rate caused by operation errors or improper equipment adjustment, thereby effectively improving the production efficiency and economic benefits of enterprises.

[0038] In an embodiment, a belt assembly 4 is further included, which includes a belt 41, a driving motor 42, a support frame 43, and a receiving groove 44. The support frame 43 is fixed to the upper surface of the machine frame 1, the driving motor 42 is used to drive the belt 41 to move on the support frame 43, and the receiving groove 44 is arranged below the movement path of the belt 41 to receive the guide wire transmitted by the belt 41.

[0039] In this embodiment, the belt assembly 4 is responsible for the initial feeding in the wire bending machine tool. It introduces the wire to be processed from the outside into the processing system and transmits the wire to the subsequent processing link through the movement of the belt 41. The belt assembly 4 includes four parts: the belt 41, the driving motor 42, the support frame 43 and the receiving groove 44. The belt 41 serves as the transmission medium responsible for carrying and transporting the wire. The belt 41 can be made of wear-resistant material with certain friction to ensure that the wire can be stably attached to the surface of the belt 41 during transportation and is not easy to slip or shift. The driving motor 42 is the power source for the movement of the belt 41, which converts electrical energy into mechanical energy to drive the belt 41 to move continuously or intermittently on the support frame 43. The support frame 43 is fixed to the upper surface of the rack 1 and serves to support and fix the belt 41, ensuring the stability and accuracy of the path of the belt 41 during operation. The receiving groove 44 is arranged below the movement path of the belt 41 to receive the wire transmitted from the belt 41, preparing for the subsequent processing link. The belt assembly 4 is the starting point of the entire wire bending machine tool, i.e. multiple wires to be processed are placed on the belt 41 to start the processing flow. The wires to be processed are placed on the belt 41 in a loose or orderly manner, and the specific manner may vary depending on the size, material or processing requirements of the wire. For example, the wires can be neatly arranged on the belt 41 by manual or automatic feeding device to ensure the accuracy of subsequent processing. The movement path and speed of the belt 41 are precisely controlled by the driving motor 42, and the operation of the driving motor 42 is controlled by the software control system through pre-set programs or real-time instructions to adjust the speed and start-stop time of the motor, thereby achieving smooth operation of the belt 41 and accurate transmission of the wire. The operation of the software control pipeline can replace manual continuous feeding, which significantly reduces the labor intensity of employees. The existing manual feeding method not only has low efficiency, but also is prone to deviation of wire position or inconsistent processing due to human operation errors. The belt assembly 4 ensures the stability and consistency of the feeding process through automated transmission combined with software control, greatly improving production efficiency.

[0040] In one embodiment, it also includes a jacking assembly 5, including a second driving member 51, a jack rod 52 and a limiting guide rail 53. The second driving member 51 is nested with the jack rod 52, the limiting guide rail 53 is fixed in the rack 1, and the second driving member 51 is used to drive the jack rod 52 to move up and down along the limiting guide rail 53, and the jack rod 52 is used to jack up the receiving groove 44.

[0041] In this embodiment, the lifting assembly 5 is used to realize the lifting function of the receiving groove 44, thereby perfecting the automatic process and processing efficiency of the guide wire bending machine tool. The lifting assembly 5 includes three main parts: the second driving member 51, the lifting rod 52 and the limiting guide rail 53, which cooperate together to realize the up-down movement of the receiving groove 44. The second driving member 51 is the power source of the lifting assembly 5, which provides driving force to make the lifting rod 52 move up and down along the limiting guide rail 53, and is lifted to a higher position after the guide wire collection is completed to facilitate subsequent transfer or stacking. The second driving member 51 can be a power device such as a pneumatic cylinder, a hydraulic cylinder or a motor, and the lifting rod 52 is the execution component of the lifting assembly 5, which is nested with the output end of the second driving member 51 through mechanical structure (such as bolt, clamping groove or other fixing method) to ensure the efficiency and stability of power transmission. The main function of the lifting rod 52 is to directly contact the lower surface of the receiving groove 44, and to lift or lower the receiving groove 44 through up-down movement. The lower surface of the receiving groove 44 is provided with a groove corresponding to the lifting rod 52, so that the lifting rod 52 can be better aligned with the receiving groove 44 during lifting to avoid sliding or deviation, thereby improving the stability and accuracy of lifting. The shape and size of the groove are adapted to the end of the lifting rod 52, for example, if the end of the lifting rod 52 is circular, the groove can be designed as a circular or semicircular recess structure to ensure that the lifting rod 52 can be stably embedded therein. Cooperation structures such as bosses, buckles or magnetic attraction devices can also be used to avoid deformation or damage due to local stress concentration. The limiting guide rail 53 provides guidance and constraint for the up-down movement of the lifting rod 52. The limiting guide rail 53 is fixed inside the rack 1 and includes a linear track or a sliding groove, and the lifting rod 52 moves along the guide rail by sliding or rolling. The presence of the limiting guide rail 53 ensures the linearity of the movement path of the lifting rod 52 and limits the deviation of the lifting rod 52 in the horizontal direction, thereby ensuring the accuracy and consistency of the lifting action. In actual application, the limiting guide rail 53 can be equipped with lubricating devices or low-friction coatings to reduce the resistance of the lifting rod 52 during movement, further improving the running efficiency of the system.

[0042] In an embodiment, a clamping assembly 6 is also included, which is arranged on the upper surface of the rack 1 opposite the feeding assembly 2, and includes a first clamping structure 61 and a second clamping structure 62 for clamping the guide wire into the guide frame 23 of the feeding assembly 2.

[0043] In the present embodiment, the main function of the clamping assembly 6 is to clamp and transfer the guide wire to be processed from the receiving groove 44 to the guide frame 23 of the feeding assembly 2. The clamping assembly 6 is arranged on the upper surface of the rack 1 (above the belt assembly 4) and opposite to the feeding assembly 2, which takes out the guide wire from the receiving groove 44 and accurately sends it into the guide frame 23 of the feeding assembly 2. The clamping assembly 6 includes a first clamping structure 61 and a second clamping structure 62, which work together to clamp different ends of the guide wire respectively to ensure that the guide wire remains stable and accurate in position during the transfer process. This improves the efficiency of clamping and the stability during the clamping and transfer process, avoiding the deviation or deformation of the guide wire caused by single-point clamping. In the processing flow, the guide wire is transmitted to the receiving groove 44 by the belt assembly 4, which serves as a temporary storage point to collect the guide wire to be processed. The receiving groove 44 is located at a lower position and has a height difference with the guide frame 23 of the feeding assembly 2. The ejector rod 52 lifts the receiving groove 44 to the height of the clamping assembly 6. The first clamping structure 61 and the second clamping structure 62 of the clamping assembly 6 are designed to clamp the two ends of the guide wire respectively. After the clamping assembly 6 completes the clamping, it transfers the guide wire to the guide frame 23 of the feeding assembly 2. Then the feeding assembly 2 drives the guide frame 23 along with the guide wire to the position of the processing assembly 3 through the driving of the first driving member 21. Through the cooperative work of the first clamping structure 61 and the second clamping structure 62, the accurate transfer of the guide wire from the receiving groove 44 to the guide frame 23 is realized.

[0044] In an embodiment, the first clamping structure 61 comprises a first horizontal moving track 611, a first horizontal moving cylinder 612, a first telescopic cylinder 613 and a first clamping piece 614. The first horizontal moving cylinder 612 is arranged at one end of the first horizontal moving track 611. The first telescopic cylinder 613 is arranged vertically on the first horizontal moving track 611. The first clamping piece 614 is connected with the output end of the first telescopic cylinder 613, and is used for clamping the first end of the guide wire. The second clamping structure 62 comprises a second horizontal moving track 621, a second horizontal moving cylinder 622, a second telescopic cylinder 623 and a second clamping piece 624. The second horizontal moving cylinder 622 is arranged at one end of the second horizontal moving track 621. The second telescopic cylinder 623 is arranged vertically on the second horizontal moving track 621. The second clamping piece 624 is connected with the output end of the second telescopic cylinder 623, and is used for clamping the second end of the guide wire. The second clamping structure 62 further comprises a first linear track 625, a first linear motor 626 and a sliding block 627. The sliding block 627 is arranged on the first linear track 625. The first linear motor 626 is used for driving the sliding block 627 to reciprocate along the first linear track 625, so that the second clamping piece 624 moves the second end of the guide wire to the side away from the first clamping structure 61.

[0045] In this embodiment, the first clamping structure 61 is composed of a first horizontal movement rail 611, a first horizontal movement cylinder 612, a first telescopic cylinder 613 and a first clamping piece 614. These components work cooperatively through mechanical connection and control to achieve the clamping and carrying of the first end of the guide wire. The first horizontal movement rail 611 is the basic support component of the first clamping structure 61, fixed on the upper surface of the machine frame 1, providing guidance and support for the horizontal movement of the first clamping structure 61. It is designed as a linear rail to ensure the stability and precision of the movement path. The first horizontal movement cylinder 612 is arranged at one end of the first horizontal movement rail 611 and is responsible for driving the entire first clamping structure 61 to move reciprocally in the horizontal direction along the rail. Through its pneumatic driving mechanism, the first horizontal movement cylinder 612 can provide sufficient thrust to enable the first clamping structure 61 to move quickly and smoothly to the target position on the rail. The first telescopic cylinder 613 is arranged vertically on the first horizontal movement rail 611 and its main function is to control the up-down movement of the first clamping piece 614. The output end of the first telescopic cylinder 613 is directly connected with the first clamping piece 614, so that when the first telescopic cylinder 613 extends or retracts, the first clamping piece 614 can move up and down in the vertical direction, thereby achieving the approach, clamping and release of the first end of the guide wire. The first clamping piece 614, as the component that directly contacts the guide wire, can be designed as a mechanical structure with clamping function, such as a jaw or clamp, to ensure accurate clamping and carrying of the first end of the guide wire into the guide frame 23 of the feeding assembly 2. The second clamping structure 62 has certain similarity with the first clamping structure 61 in function. The second clamping structure 62 includes a second horizontal movement rail 621, a second horizontal movement cylinder 622, a second telescopic cylinder 623 and a second clamping piece 624, which have similar basic components as the first clamping structure 61, but its working target is to operate the other end of the guide wire. The second horizontal movement rail 621 is also fixed on the upper surface of the machine frame 1 and is arranged opposite to the first horizontal movement rail 611, forming the two-side support structure of the clamping assembly 6. The second horizontal movement cylinder 622 is arranged at one end of the second horizontal movement rail 621 and drives the second clamping structure 62 to move horizontally along the rail. The second telescopic cylinder 623 is arranged vertically on the second horizontal movement rail 621 and is connected with the second clamping piece 624, responsible for controlling the up-down movement of the second clamping piece 624. The second clamping piece 624 is similar to the first clamping piece 614 and is designed as a mechanical structure capable of clamping the guide wire, used for clamping the second end of the guide wire. Simultaneous clamping of both ends can ensure the stability and accuracy of the guide wire during processing. The second clamping structure 62 further includes a first linear rail 625, a first linear motor 626 and a slider 627, which add an additional degree of freedom to the second clamping structure 62. Specifically, the slider 627 is arranged on the first linear rail 625 and driven by the first linear motor 626 to move reciprocally along the first linear rail 625.The setting direction of the first linear track 625 is generally perpendicular to the second horizontal moving track 621, so that the second clamping member 624 can move along the first linear track 625 to the side away from the first clamping structure 61 after clamping the second end of the guide wire. In the initial state, the guide wire can be in a loose or partially wound state, and the two clamping structures are close to the same end of the guide wire to facilitate simultaneous contact with the guide wire. The first clamping structure 61 clamps the first end of the guide wire through the first clamping member 614, and fixes and positions the first end of the guide wire to the appropriate height and position through the cooperation of the first horizontal moving cylinder 612 and the first telescopic cylinder 613. At the same time, the second clamping structure 62 clamps the guide wire through the second clamping member 624, and moves the second clamping member 624 along the first linear track 625 away from the first clamping structure 61 after clamping the guide wire by using the cooperation of the second horizontal moving cylinder 622, the second telescopic cylinder 623, and the first linear motor 626 and the slider 627. This movement process is equivalent to a stretching and combing action on the guide wire, which can effectively straighten the guide wire and eliminate the winding or knot phenomenon that may occur during the conveying process. In this way, the guide wire is conveyed to the guide frame 23 of the feeding assembly 2 in a flat manner, providing a neat and stable guide wire input for subsequent processing procedures.

[0046] In actual operation, the movement process of the first clamping structure 61 and the second clamping structure 62 can be divided into the following stages: first, the two clamping structures approach the initial position of the guide wire simultaneously, and the clamping members are in contact with the guide wire through the downward movement of the telescopic cylinder; the first clamping member 614 and the second clamping member 624 clamp one end of the guide wire; the second clamping structure 62 moves along the first linear track 625 by driving the first linear motor 626 to stretch the guide wire and eliminate winding; finally, the two clamping structures convey the guide wire to the guide frame 23 of the feeding assembly 2 through the cooperation of the horizontal moving cylinders, and release the guide wire to the clamping structure of the guide frame 23.

[0047] In an embodiment, the feeding assembly 2 further comprises a third clamping member 24 fixedly connected to the side of the guide frame 23 close to the sliding track 22, for clamping the guide wire clamped by the clamping assembly 6.

[0048] In this embodiment, the specific role of the third clamping piece 24 is to clamp the guide wire transmitted by the clamping assembly 6 and fix it on the guide frame 23. The guide frame 23 serves as a load-bearing structure for the guide wire, and it does not have the ability to actively clamp the guide wire. The clamping assembly 6 (including the first clamping structure 61 and the second clamping structure 62) is responsible for grabbing the guide wire from the outside and feeding it into the guide frame 23. The third clamping piece 24 clamps the guide wire transmitted by the clamping assembly 6 and can stably fix it on the guide frame 23, avoiding the guide wire from shifting or falling during subsequent movement or processing. The third clamping piece 24 is fixed on the side of the guide frame 23 close to the sliding track 22. The sliding track 22 is the path of the movement of the guide frame 23. The third clamping piece 24 is close to the sliding track 22, which can more efficiently receive the guide wire sent by the clamping assembly 6, and also facilitates maintaining the stability of the guide wire when the guide frame 23 moves along the sliding track 22. The clamping action of the third clamping piece 24 can be achieved by mechanical clamping, pneumatic clamping or other methods, ensuring the reliable positioning of the guide wire in the feeding assembly 2, providing a stable material basis for the bending operation of the subsequent processing assembly 3, and making the entire process from external clamping to feeding to processing more coherent and efficient. It is worth noting that the third clamping piece 24 includes two, the first clamping piece is fixed on the guide frame 23, and the second clamping piece is arranged on the side of the sliding track 22 close to the first driving piece 21, and is provided with a pneumatic cylinder for driving the second clamping piece to move along the sliding track 22 towards the first clamping piece, for pushing the guide wire into the processing assembly 3.

[0049] In an embodiment, the guide frame 23 includes a fixed plate 231 and a guide groove 232, and a plurality of V-shaped grooves 233 adapted to the guide wire are arranged on the guide groove 232.

[0050] In this embodiment, the guide frame 23 is composed of a fixed plate 231 and a guide groove 232. The fixed plate 231 is the main structure of the guide frame 23, which plays a supporting and fixing role. The guide groove 232 is the part that directly contacts the guide wire, which is used for positioning and guiding the guide wire. Specifically, a plurality of V-shaped grooves 233 are arranged on the guide groove 232. The interval design and shape adaptation of these V-shaped grooves 233 are to accommodate the guide wire. The guide wire is usually an elongated and flexible metal or non-metal wire. The geometric shape of the V-shaped groove 233 can naturally restrict the guide wire at the bottom of the groove, ensuring the positioning accuracy of the guide wire on the guide frame 23. The interval design of the V-shaped groove 233 can adapt to guide wires of different diameters or shapes. The slope of the V-shaped groove 233 can adaptively restrict the lateral movement of the guide wire, reducing the shaking or deviation of the guide wire during processing.

[0051] In an embodiment, a heating mechanism 7 is arranged on the rack 1 and relative to the processing assembly 3. The heating mechanism 7 is used for heating and shaping the guide wire on the rotating platform 32.

[0052] In the present embodiment, the guide wire after bending may have the problem of springback or shape instability due to the elasticity or internal stress of the material, and such springback phenomenon will significantly affect the product quality. The heating mechanism 7 is arranged on the rack 1 and opposite to the machining assembly 3, and is close to the rotating platform 32 in the spatial layout, and can directly heat the guide wire on the rotating platform 32. The principle of the heating and shaping treatment is to apply appropriate heat to the guide wire, so that the material thereof reaches a certain plastic deformation state after bending, thereby fixing the bending shape and eliminating or reducing the springback phenomenon. For example, for a metal guide wire, heating can make it reach an annealing or softening state, reducing the internal stress of the material; for some polymer guide wires, heating can make it reach above the glass transition temperature, thereby realizing permanent shaping of the shape. The specific implementation mode of the heating mechanism 7 can include electric heating, infrared heating or hot air heating, etc., and the guide wire is precisely heat-treated to ensure the stability and consistency of the bending shape.
