Abstract
Description
Technical Field
[0001] The present application relates to the technical field of titanium wire butt welding, and in particular to an axial butt welding device for titanium wire ends. Background Art
[0002] Titanium wire is a slender metal wire made of pure titanium material. Common specifications include φ0.8-φ6.0mm and φ0.2-φ8.0mm. Titanium wire is widely used in many fields, such as military industry, medical industry, and other industries. Due to its biocompatibility and corrosion resistance, titanium wire is widely used in the manufacture of artificial joints, dental implants, surgical implants and other medical devices; at the same time, its light weight and high strength also make it an indispensable material in the aerospace industry and transportation manufacturing.
[0003] At present, the processing process of titanium wire is mainly to form a small diameter titanium rod through multiple diameter reduction drawing. The current wire drawing operation process is continuous wire drawing. Therefore, in order to realize the continuous wire drawing operation, it is usually necessary to weld one end of the separate wire drawing coil to be drawn, that is, to form an overall large wire drawing coil, and then realize continuous wire drawing operation without the need for frequent shutdown and other operation processes.
[0004] At present, titanium wire butt welding uses a butt welding device, the structure of which is as shown in the attached manual. Figure 1 As shown, it includes a butt welding platform, on which a bottom plate is linearly symmetrically arranged, and a pressing plate that can be pressed against the top side of each bottom plate is arranged, and one side (such as Figure 1 The bottom plate and the pressure plate (on the right side of the middle) are slidably arranged on the welding platform toward the bottom plate on the other side. Figure 2 As shown, during the butt welding operation, the titanium wire to be butt welded is clamped between the pressure plate and the bottom plate (specifically, a compression screw is rotatably connected to the top of the pressure plate, and the compression screw is fixed to the side wall of the bottom plate. By rotating the compression screw, the pressure plate is driven downward to achieve the pressing and fixing of the titanium wire, as shown in FIG. Figure 2 As shown), then, Figure 3-4 As shown, the bottom plate on the right is driven to move toward the left as a whole (specifically, a driving rod is hinged on the bottom plate on the right, and the driving rod is driven to rotate to realize the sliding of the bottom plate on the right as a whole), so that the end of the titanium wire clamped on the right is abutted against the titanium wire on the left, and the hot-melt welding of the butted titanium wire ends is achieved by electric heating of the bottom plate. After welding is completed, the clamping screw is rotated in the opposite direction to disassemble the butt-welded titanium wire.
[0005] However, due to the small diameter of the titanium wire, its end is inevitably affected by external forces and has axial deflection and bending, such as Figure 5 As shown, when clamped between the base plate and the pressure plate, the ends of the titanium wires being welded cannot achieve axial correspondence, resulting in axial deflection after welding, which affects the welding strength of the ends and the smooth progress of subsequent wire drawing, and may cause wire drawing jamming and breakage. Summary of the invention
[0006] In response to the above-mentioned problems, the present application aims to provide an axial butt-welding device for titanium wire ends, which performs axial trimming on the ends of the titanium wires on each side before butt-welding the ends of the titanium wires, thereby improving the axial correspondence accuracy and quality of butt-welding.
[0007] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a titanium wire end axial butt welding device, comprising a butt welding platform, on which a base plate is arranged in a linear symmetrical manner, and a pressure plate that can be pressed against the top side of the base plate on each side is arranged, and the base plate and the pressure plate on one side are slidably arranged on the butt welding platform toward the base plate on the other side, and it is characterized in that: a trimming mechanism that drives the titanium wire end to deform and tend to a straight line state is arranged between the symmetrical base plate and the pressure plate.
[0008] Preferably, the trimming mechanism comprises a trimming cylinder which is arranged on a butt welding platform between symmetrical base plates and is coaxial with the titanium wire fixed between the base plate and the pressure plate, and the base plate and the pressure plate on the other side are arranged as a sliding structure.
[0009] Preferably, the inner wall of the trimming cylinder is configured as a symmetrical conical surface structure.
[0010] Preferably, the trimming cylinder is configured as a half-hinged structure, and an adjustment support rod is provided between the bottom of the trimming cylinder and the welding platform.
[0011] The beneficial effect of the present application is that the trimming mechanism provided can perform axial trimming on the ends of the titanium wires on each side before the ends of the titanium wires are butt-welded, thereby improving the axial correspondence accuracy and quality of the butt-welding, and solving the problem of sticking and breakage of the titanium wires that may occur during subsequent titanium wire drawing.

[0023] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.
[0024] See attached Figures 1 to 9 The titanium wire end axial butt welding device shown in the figure comprises a butt welding platform 1, on which a bottom plate 2 is linearly symmetrically arranged, and a pressing plate 3 that can be pressed against the top side of each bottom plate 2 is arranged, and one side (such as Figure 1 The bottom plate 2 and the pressing plate 3 are slidably arranged on the butt welding platform 1 toward the bottom plate 2 on the other side. The titanium wire to be butt welded is clamped by the butt welding device, that is, the end butt welding is achieved by electric heating hot melt welding.
[0025] In order to solve the problem that the titanium wire end is prone to deflection and bending, which affects the welding quality and the subsequent smooth wire drawing, Figure 6 As shown, a trimming mechanism for driving the titanium wire end to deform and tend to a straight state is arranged between the symmetrical bottom plate 2 and the pressure plate 3. That is, the trimming mechanism can trim the end of each side of the titanium wire axially before the titanium wire end is butt-welded, thereby improving the axial correspondence accuracy during butt welding and the butt welding quality.
[0026] Specifically, Figure 6-7 As shown, the trimming mechanism includes a trimming cylinder 4 which is arranged on the butt welding platform 1 between the symmetrical bottom plates 2 and is coaxial with the titanium wire fixed between the bottom plate 2 and the pressure plate 3. After the titanium wire is clamped near the end by the bottom plate 2 and the pressure plate 3 on each side, the bottom plate 2 on the right side is driven to slide, and then the titanium wire end on this side is extended into the trimming cylinder 4, and the inner wall of the trimming cylinder 4 is contacted with the end to achieve axial external force trimming, thereby improving the axial accuracy of the end.
[0027] To facilitate trimming of the titanium wire end on the left, Figure 3The bottom plate 2 and the pressing plate 3 on the left side are set as sliding structures. During operation, the bottom plates 2 on both sides are driven to slide toward each other, so that the ends of the titanium wires on both sides are synchronously inserted into the trimming cylinder 4, and the ends are synchronously trimmed. Then, welding is performed by electric heating, which can ensure the axial welding accuracy. After welding is completed, the titanium wire is pulled out of the trimming cylinder 4, and continuous wire drawing operation can be performed.
[0028] Since the bent titanium wire at the end is difficult to smoothly penetrate into the trimming tube 4 for trimming, in order to facilitate the insertion of the end, Figure 6-7 As shown, the inner wall of the trimming cylinder 4 is set to a symmetrical conical surface structure. The outer port of the conical surface structure facilitates the smooth insertion of the curved end. After the insertion, the inner diameter of the trimming cylinder 4 is gradually reduced, so that the trimming effect of the curved end is achieved.
[0029] Since the overall length of the titanium wire increases after welding, it is difficult to quickly pass through the trimming tube 4. Therefore, in order to solve this problem, Figure 8 As shown, the trimming cylinder 4 is configured as a half-hinged structure. After the above-mentioned butt welding is completed, the trimming cylinder 4 can be opened to directly separate and disassemble the titanium wire from the trimming cylinder 4, thereby improving the efficiency of the butt welding operation.
[0030] After high-temperature fusion welding, the outer diameter of the welding part will increase, and the high-temperature fusion welding state will cause adhesion with the inner wall of the trimming tube 4, and it is difficult to disassemble the titanium wire and the trimming tube 4 later. Therefore, in order to solve this problem, Fig. 9 As shown, an adjustment support rod 5 is provided between the bottom of the trimming cylinder 4 and the butt welding platform 1. It is preferably an inner and outer rod structure, and the length is adjusted by inserting a pin. Before butt welding, the trimming cylinder 4 is lifted by the adjustment support rod 5 to correspond to the axial direction of the titanium wire, and the titanium wire is passed through to perform trimming. When the trimming is completed and butt welding is performed, the trimming cylinder 4 is opened and driven to separate from the titanium wire by the adjustment support rod 5. Fig. 9 As shown, a butt welding connection can be performed and the adhesion effect with the trimming cylinder 4 can be solved.
[0031] The principle of the present application is: during the butt-welding operation of the titanium wire, the titanium wire is first clamped on the symmetrical base plate 2 and the pressure plate 3, and after the trimming cylinder 4 is lifted to correspond to the axial direction of the titanium wire by adjusting the support rod 5, the base plates 2 on both sides are driven towards each other so that the end of the titanium wire penetrates into the inner wall of the trimming cylinder 4 to achieve axial trimming. When the trimming is completed and butt-welding is performed, the trimming cylinder 4 is opened and the support rod 5 is adjusted to drive it to separate from the titanium wire, and then the butt-welding connection can be performed. After the butt-welding is completed, the pressure plate 3 is released to achieve the removal of the titanium wire.
[0032] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
