Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, specifically to a titanium alloy welding wire cutting device. Background Technology

[0002] Titanium alloy welding wire, with its excellent strength, corrosion resistance, and biocompatibility, is increasingly widely used in precision manufacturing fields such as aerospace, medical devices, and high-end chemicals. The processing precision of this type of welding wire directly affects the subsequent welding quality and product performance; therefore, extremely high requirements are placed on the consistency of its cut length and the flatness of its ends.

[0003] Titanium alloys are characterized by low yield strength and good plasticity. During the cutting process, they are prone to bending due to stress deformation. When the cutter of a traditional cutting device comes into contact with the welding wire, the soft welding wire is difficult to withstand instantaneous shear force and compressive stress. Without targeted constraint design, the cutting part will undergo plastic bending laterally or axially, forming deformations such as "sickle" or "wave". This bending not only directly causes deviations in the cutting length, but also causes defects such as burrs and curled edges at the end of the welding wire, making it difficult to meet the requirements of high-precision cutting of titanium alloy welding wire. Utility Model Content

[0004] The purpose of this utility model is to provide a titanium alloy welding wire cutting device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model relates to a titanium alloy welding wire cutting device, comprising: Cut the frame; The clamping component includes a side plate, an internal threaded ring, a clamping ring, a rotating shaft, a lead screw, and a handle. The internal threaded ring is disposed at one end of the outer surface of the side plate, the lead screw is threaded in the middle of the internal threaded ring, the handle is fixedly connected to one end of the lead screw, the rotating shaft is disposed at the other end of the lead screw, and the clamping ring is disposed at the outer end of the rotating shaft.

[0005] Furthermore, nylon wheels are installed on the top of the cutting frame, and the nylon wheels are symmetrically distributed.

[0006] Furthermore, upright plates are fixed to both ends of the outer surface of the cutting frame, and a support rod is provided on the upper part of one end of the upright plate, with a spring wound around the outer surface of the support rod.

[0007] Furthermore, a pressure plate is slidably connected through the outer surface of the support rod, and a horizontal plate is fixedly connected to the top and bottom of the pressure plate.

[0008] Furthermore, uprights are provided at both the top and bottom of the nylon wheel, and the horizontal plate is fixed between the pressure plate and the uprights.

[0009] Furthermore, it also includes a cutting component, which includes an upper cylinder, an upper cutter, an upper support frame, a lower cylinder, a lower cutter, and a lower support frame. The upper support frame is welded to one end of the outer surface of the cutting frame. The upper cylinder is located at the top of the upper support frame. The top of the upper cutter passes through the upper support frame and is connected to the output end of the upper cylinder. The lower support frame is welded to the lower part of the inner surface of the upper support frame. The lower cylinder is located at the bottom of the lower support frame.

[0010] Furthermore, a base is fixedly connected to one side of the outer surface of the cutting frame, and the base is supported on the bottom of the lower cylinder.

[0011] This utility model has the following beneficial effects: This invention, through its clamping component, allows the threaded rod to rotate by hand-holding the handle after the titanium alloy welding wire is fed to the preset cutting position. The rotation shaft drives the clamping ring to hold the welding wire near the cutting point, thus rigidly fixing the welding wire at the cutting point. The nylon wheels at both ends provide reasonable pressure through springs, forming a continuous clamping constraint on the welding wire. This prevents the cutting part from undergoing plastic bending laterally or axially during the cutting process, thus avoiding deformation such as "sickle-shaped" or "wavy" shapes, and meeting the requirements for high-precision cutting of titanium alloy welding wire.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a titanium alloy welding wire cutting device, comprising: Cut off frame 11; The clamping component includes a side plate 21, an internal threaded ring 22, a clamping ring 23, a rotating shaft 24, a lead screw 25, and a handle 26. The internal threaded ring 22 is disposed at one end of the outer surface of the side plate 21, the lead screw is threaded in the middle of the internal threaded ring 22, the handle 26 is fixedly connected to one end of the lead screw, the rotating shaft 24 is disposed at the other end of the lead screw, and the clamping ring 23 is disposed at the outer end of the rotating shaft 24. After the titanium alloy welding wire is fed to the preset cutting position, the threaded rod is driven to rotate by holding the handle 26. The rotation shaft 24 drives the clamping ring 23 to clamp the welding wire in the vicinity of the cutting point, so that the welding wire is rigidly fixed at the cutting point. This prevents the cutting part from plastically bending laterally or axially during the cutting operation, thus avoiding deformation such as "sickle-shaped" or "wavy" shapes, and meets the requirements for high-precision cutting of titanium alloy welding wire.

[0018] The clamping ring 23 is made of hard alloy, and the inner surface has an arc groove to fit with the welding wire, which avoids pinching damage and enhances restraint.

[0019] Nylon wheels 31 are mounted on the top of the cutting frame 11, and the nylon wheels 31 are symmetrically distributed. The nylon wheels 31 at both ends provide reasonable pressure through the springs 36, forming a continuous clamping constraint on the welding wire.

[0020] The two ends of the outer surface of the cutting frame 11 are fixed with upright plates 32, and a support rod 37 is provided on the upper part of one end of the upright plate 32. A spring 36 is wound around the outer surface of the support rod 37. When the springs 36 at both ends are compressed, they will undergo elastic deformation. The accumulated elastic force is transmitted to the nylon wheels 31 at both ends, so that the nylon wheels 31 receive reasonable pressure. Since the nylon wheel 31 is in contact with one end of the outer surface of the titanium alloy welding wire, this pressure will be converted into a continuous clamping force on the welding wire, thereby achieving effective constraint on the rear end of the welding wire.

[0021] A pressure plate 35 is slidably connected through the outer surface of the support rod 37, and a horizontal plate 34 is fixedly connected to the top and bottom of the pressure plate 35. When the pressure plate 35 is subjected to external force, it will transmit the force to the horizontal plate 34, which in turn will compress the spring 36 connected to the horizontal plate 34.

[0022] The nylon wheel 31 is provided with uprights 33 at both the top and bottom, and the horizontal plate 34 is fixed between the pressure plate 35 and the uprights 33; The linkage structure formed by the upright 33, the horizontal plate 34 and the pressure plate 35 begins to function.

[0023] Working principle: When the titanium alloy welding wire is fed to the preset cutting position by the feeding mechanism, the operator holds the handle 26 and rotates it. The rotation of the handle 26 directly drives the threaded rod to rotate synchronously. Since the rotating shaft 24 is connected between the clamping ring 23 and the threaded rod, the rotation of the threaded rod is transmitted to the clamping ring 23 through the rotating shaft 24, causing the clamping ring 23 to perform a clamping action in opposite directions, clamping the titanium alloy welding wire in the vicinity of the cutting point. At the same time, when the pressure plate 35 is subjected to external force, it will transmit the force to the horizontal plate 34, which will then compress the spring 36 connected to the horizontal plate 34, so that the nylon wheel 31 receives reasonable pressure.

[0024] In this step, the rigid support of the clamping ring 23 ensures that the welding wire near the cut-off point will not undergo lateral displacement or bending, while the continuous constraint generated by the nylon wheel 31 under the pressure of the spring 36 effectively prevents the welding wire from moving longitudinally due to "loosening" at the rear end, thus achieving the consistency of the welding wire length and the integrity of the end quality after cutting.

[0025] Please see Figure 1 , Figure 2 As shown, this embodiment, based on the above embodiment, further includes: The cutting component includes an upper cylinder 41, an upper cutter 42, an upper support frame 43, a lower cylinder 44, a lower cutter 45, and a lower support frame 47. The upper support frame 43 is welded to one end of the outer surface of the cutting frame 11. The upper cylinder 41 is located on the top of the upper support frame 43. The top of the upper cutter 42 passes through the upper support frame 43 and is connected to the output end of the upper cylinder 41. The lower support frame 47 is welded to the lower part of the inner surface of the upper support frame 43. The lower cylinder 44 is located at the bottom of the lower support frame 47. The bottom of the lower cutter 45 passes through the lower support frame 47 and is connected to the output end of the lower cylinder 44. Both the upper cutter 42 and the lower cutter 45 have beveled blades that work together to reduce the impact on the welding wire during the cutting process and to prevent burrs and deformation at the end of the welding wire.

[0026] A base 46 is fixedly connected to one side of the outer surface of the cutting frame 11, and the base 46 is supported on the bottom of the lower cylinder 44. Working principle: When the upper cylinder 41 and the lower cylinder 44 are working, the pressure energy of the compressed air is converted into mechanical energy through the reciprocating motion of the internal piston. The output end is connected to the load, driving the load to move. In the connection between the upper cutter 42 and the upper cylinder 41, and the lower cutter 45 and the lower cylinder 44, the upper cutter 42 and the lower cutter 45, as the load of the upper cylinder 41 and the lower cylinder 44, need to move up and down with the movement of the upper cylinder 41 and the lower cylinder 44 to achieve the cutting function. Therefore, the upper cutter 42 and the lower cutter 45 are connected to the output ends of the upper cylinder 41 and the lower cylinder 44 respectively. For example, the piston rod ends of the upper cylinder 41 and the lower cylinder 44 are fixedly connected to the upper cutter 42 and the lower cutter 45 by bolts, pins, etc., so that the upper cutter 42 and the lower cutter 45 are driven by the upper cylinder 41 and the lower cylinder 44 to complete the cutting action.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
