DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0025] In the manufacture and processing of metal mesh tubes, the metal mesh tubes usually include a supporting core rod for maintaining its shape and stability during the processing. However, after the metal mesh tube is processed, the supporting core rod needs to be pulled out of the metal mesh tube for further use or processing of the metal mesh tube. Traditional core pulling methods usually rely on manual operation, which is not only inefficient, but also poses safety hazards, such as the risk of workers' hand injuries. In addition, manual operation is also difficult to ensure the accuracy and consistency of the core pulling process, which may cause damage to the metal mesh tube or the core rod cannot be completely pulled out. The support core rod extraction device for the metal mesh tube provided in the present application is highly automated, accurate and adaptable, and is used to solve the problem that the support core rod in the current processing of metal bent tubes for bronchoscopes relies on manual extraction, which is inefficient and poses safety risks.

[0026] The specific structure of the supporting core rod extraction device for the metal mesh tube provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figure 1 As shown, a support mandrel extraction device for a metal mesh tube provided in an embodiment of the present application is used to separate a metal mesh tube 1 and a support mandrel 2. The device includes a first workbench 3 and a second workbench 4, wherein the first workbench 3 includes a table 31 and a pressing block 32, the table 31 and the pressing block 32 are movably connected, and the adjacent surfaces of the table 31 and the pressing block 32 are respectively provided with grooves with semicircular cross-sections for placing the metal mesh tube 1 with the support mandrel 2. It can be understood that the radius of the semicircle should match the diameter of the metal mesh tube 1, the stability of the fixation of the metal mesh tube 1 should be ensured, and at the same time, the metal mesh tube 1 should not be damaged by excessive extrusion.

[0028] The second workbench 4 includes a guide rail 41 and a metal mesh tube block 42. The metal mesh tube block 42 is located at one end of the second workbench 4 close to the first workbench 3. The metal mesh tube block 42 is fixedly connected to the second workbench 4. The metal mesh tube block 42 has a through hole 421. The diameter of the through hole 421 is larger than the diameter of the support mandrel 2 and smaller than the diameter of the metal mesh tube 1. When in use, the metal mesh tube 1 with the support mandrel 2 is placed in the groove of the first workbench 3 and fixed with a pressing block 32. At this time, the support mandrel 2 passes through the through hole 421, and the metal mesh tube 1 is blocked by the metal mesh tube block 42.

[0029] A rack track 43 is arranged on the top surface of the guide rail 41, and the rack track 43 is parallel to the semicircular groove. A control component 5 and a clamping component 6 are arranged on one end of the second workbench 4 close to the first workbench 3. The clamping component 6 is connected to the control component 5, and the control component 5 is used to control the clamping component 6 to move back and forth along the rack track 43. When in use, the clamping component 6 clamps the support core rod 2, and at the same time, the control component 5 drives the clamping component 6 to move away from the first workbench 3. At this time, the support core rod 2 is pulled out of the metal mesh tube 1 to achieve the separation of the two. After separation, the clamping component 6 is released, the support core rod 2 falls, and the pressing block 32 is removed to take out the metal mesh tube 1. Furthermore, a collection box can be set at the bottom of the second workbench 4 to achieve the collection of the support core rod 2.

[0030] The supporting core rod extraction device for the metal mesh tube provided in the present application, the table plate 31 and the pressure block 32 of the first workbench 3 are designed with movable connections and semicircular grooves, which can stably fix the metal mesh tube 1 to prevent displacement or deformation during the separation process. Through the precise cooperation of the control component 5 and the clamping component 6, the core rod 2 can be efficiently supported and extracted from the metal mesh tube 1, with high production efficiency and effectively reducing safety risks.

[0031] Reference Figure 2 As shown, in some embodiments, the control component includes a controller 51, a stepper motor 52 and a gear 53. The controller 51 is electrically connected to the stepper motor 52. The rotating shaft of the stepper motor 52 is connected to the rotating shaft of the gear 53 to control the rotation of the gear 53. The gear 53 is engaged with the rack track 41.

[0032] The controller 51 is used to control the start, stop and reversal of the stepper motor 52. After the stepper motor 52 is started, the driving gear 53 moves on the rack track 43, thereby achieving precise positioning and smooth movement of the clamping assembly 6, and improving the accuracy and stability of the operation.

[0033] In some embodiments, the control assembly further includes an inertial roller 54, and two inertial rollers 54 respectively roll along the bottom surface of the guide rail 41. The inertial rollers 54 ensure that the control assembly 5 moves more stably and smoothly.

[0034] In some embodiments, the control assembly 5 includes a control cabinet 55, and the control cabinet 55 is provided with a through hole 56 for the guide rail 41 and the rack rail 43 to pass through, and the control cabinet 55 is slidably connected to the second workbench 4. The design of the control cabinet 55 allows the control assembly 5 and the second workbench 4 to form a whole, which is convenient for movement and installation. At the same time, the provision of the through hole 56 allows the guide rail 41 and the rack rail 43 to pass through smoothly without affecting the normal operation of the control assembly 5.

[0035] Reference Figure 3As shown, in some embodiments, the clamping assembly 6 includes a mounting plate 61, a cylinder 62 and a clamp 63; the clamp 63 includes two L-shaped clamps 631, the L-shaped clamp 631 includes a first connecting rod 6311 and a second connecting rod 6312, one end of the first connecting rod 6311 and one end of the second connecting rod 6312 are rotatably connected, one end of the two first connecting rods 6311 is fixedly connected to the mounting plate 61, the other ends of the two second connecting rods 6312 intersect and a rotating shaft 6313 is arranged at the intersection, the cylinder 62 is fixedly connected to the mounting plate 61, and the output end of the cylinder 62 is connected to the rotating shaft 6313 for controlling the rotation of the rotating shaft 6313.

[0036] The design of the clamping assembly 6 enables the clamping jaws 63 to be flexibly opened and closed to adapt to the support mandrels 2 of different diameters. The cylinder 62 drives the rotating shaft 6313 to rotate, thereby controlling the opening and closing of the clamping jaws 63 to achieve the clamping and loosening of the support mandrel 2.

[0037] In some embodiments, an anti-sliding block 632 is provided at one end of the clamping jaw 63 close to the first workbench 3. The design of the anti-sliding block 632 increases the friction between the clamping jaw 63 and the supporting mandrel 2, prevents the supporting mandrel 2 from slipping during the extraction process, and improves the stability of the operation.

[0038] In some embodiments, the first workbench 3 further includes a quick clamp 33, which is close to the pressing block 32 and fixedly connected to the table 31, and is used to fix the pressing block 32. The design of the quick clamp 33 enables the pressing block 32 to be quickly fixed and released, which is convenient for the operator to adjust the position of the pressing block 32 according to needs, thereby improving work efficiency.

[0039] In some embodiments, a plurality of height adjusters 7 are provided at the bottom of the first workbench 3 and the second workbench 4. The height adjusters 7 enable the heights of the first workbench 3 and the second workbench 4 to be adjusted to adapt to operating environments with different height requirements, thereby improving the flexibility and applicability of the device.

[0040] According to the above technical features, the working process of the support mandrel extraction device for the metal mesh tube provided by the present application is:

[0041] Place the metal mesh tube 1 with the supporting core rod 2 in the groove on the first workbench 3, fix it with the pressure block 32, and further fix it firmly with the quick clamp 33. At this time, one end of the supporting core rod 2 passes through the through hole 421 on the metal mesh tube block 42 and is clamped by the clamp 63. Start the start button of the controller 51, and the stepper motor 52 drives the gear 53 to rotate, thereby realizing the movement on the rack track 43. At this time, the gear 53 moves away from the first workbench 3, thereby pulling the supporting core rod 2 out of the metal mesh tube 1. When the gear 53 moves to the designated position, the stepper motor 52 stops working, the gear 53 stops rotating, the clamp 63 is released, and the supporting core rod 2 falls. After a preset delay time, the controller 51 controls the stepper motor 52 to reverse and return to the initial position.
