When the insertion rod 3051 moves, the positioning seat 3091 on the side wall of the insertion rod 3051 drives the push plate 309 to move, and the push plate 309 is tilted as a whole, and the push plate 309 slides relative to the protrusion 3082, so that the protrusion 3082 is closer and closer to the rotation center of the push plate 309.

Finally, when the push plate 309 rotates to a certain angle, the outermost side of the push plate 309 can fix the side wall of the semi-finished titanium ring 500.

[0030] The implementation principle of the method for preparing a cathode roller titanium ring by welding forming in this embodiment is as follows: First, the two ends of the TA1 titanium plate raw material are beveled and then rolled into a circle using a four-roller plate rolling machine.

[0031] Then, the semi-finished titanium ring 500 is placed as a whole in the installation unit 100, and the semi-finished titanium ring 500 is preliminarily positioned by the feeding unit 200, and then the semi-finished titanium ring 500 is completely positioned by the positioning locking unit 300, and finally the weld of the semi-finished titanium ring 500 is welded by the welding unit 400.

[0032] The operator then places the semi-finished titanium ring 500 in the inner groove 102 , and the semi-finished titanium ring 500 is placed as a whole in the space between the guide slider 2014 and the top plate 202 .

[0033] Then the operator starts the drive motor 2011, and drives the screw shaft 201 to rotate through the drive motor 2011. At this time, the guide slider 2014 on the screw shaft 201 can slide along the guide slider 2014, and the guide slider 2014 passes through the partition 2013. The fixed seat 301 on the top of the guide slider 2014 starts to move synchronously toward the semi-finished titanium ring 500.

[0034] When the bearing plate 3021 on the side wall of the fixing seat 301 and the semi-finished titanium ring 500 are in contact and squeezed, the fixing seat 301 and the top plate 202 can axially fix the semi-finished titanium ring 500. In addition, during the squeezing process, the bearing plate 3021 and the pressure rod 302 are subjected to squeezing force, which can allow the pressure rod 302 to move into the inner cavity 3011 of the fixing seat 301, wherein the limiting plate 3022 mainly serves the purpose of limiting, and when the pressure rod 302 slides, the synchronous plate 303 on the pressure rod 302 can slide synchronously, and the synchronous plate 303 compresses the reset spring 3033 in the inner cavity, and the reset spring 3033 facilitates the later reset.

[0035] When the synchronous plate 303 slides, the mounting seat 3031 on the side wall of the synchronous plate 303 slides synchronously, and the sliding rod 3032 on the mounting seat 3031 slides in the strip groove 3041 of the swing arm 304, thereby driving the swing arm 304 to swing as a whole. The swing arm 304 can drive the sleeve 305 to swing as a whole through the synchronous shaft 3042.

[0036] When the swing arm 304 rotates through the synchronous shaft 3042, the sleeve 305 can drive the inserted rod 3051 to swing, and finally the rod 3051 and the top pressure plate 3052 rotate to the inside of the semi-finished titanium ring 500 (the initial position is not in the semi-finished titanium ring 500, in order to facilitate the vertical placement of the semi-finished titanium ring 500). During the rotation of the rod 3051, the guide rod 3053 on the side wall of the rod 3051 first slides inside the arc groove 3061. When sliding from the arc groove 3061 to the straight groove 3062, the entire guide rod 3053 tends to slide outward, thereby driving the rod 3051 to slide outward relative to the sleeve 305, and then the rod 3051 drives the top pressure plate 3052 to slide outward, thereby squeezing the inner cavity at the top of the semi-finished titanium ring 500.

[0037] And when the sleeve 305 rotates, the sleeve 305 can drive the cantilever 307 and the seesaw 3071 of the side wall to rotate to the lower part of the inner cavity of the semi-finished titanium ring 500, and when the insertion rod 3051 slides, the insertion rod 3051 can drive the synchronous bracket 3076 to slide outward, and the synchronous bracket 3076 slides in the through groove of the cantilever 307 at this time, and the U-shaped bracket 3075 and the pull rod 3074 at the bottom of the synchronous bracket 3076 can slide synchronously, and the pull rod 3074 slides in the positioning groove 3073 of the seesaw 3071 at this time, and finally can drive the seesaw 3071 to rotate, and the seesaw 3071 rotates the bottom pressure plate 3072 at the end downward, and is squeezed and fixed with the bottom of the semi-finished titanium ring 500, thereby further achieving the purpose of positioning.

[0038] And when the insertion rod 3051 moves, the positioning seat 3091 on the side wall of the insertion rod 3051 drives the push plate 309 to move, and the push plate 309 is tilted as a whole, and the push plate 309 slides relative to the protrusion 3082, so that the protrusion 3082 is closer and closer to the rotation center of the push plate 309. At this time, the push plate 309 is pushed to rotate a larger angle, and the torsion spring 3092 is twisted synchronously at this time, and the torsion spring 3092 is used to facilitate later resetting. Finally, when the push plate 309 rotates to a certain angle, the outermost side of the push plate 309 can fix the side wall of the semi-finished titanium ring 500.

[0039] The present invention fixes the semi-finished titanium ring 500 in the axial direction and the radial direction through a driving source, which is simple to operate and has a lower manufacturing cost.

[0040] After the fixing is completed, the operator can perform welding operation through the plasma automatic welding machine body 401, and the plasma automatic welding machine body 401 can slide on the guide rail 4022 of the flat plate 4021, so that welding operation can be performed at different positions.

[0041] Finally, the welded titanium ring is placed in an electric heat treatment furnace for high-temperature homogenization heat treatment; the heat-treated titanium ring is rolled and deformed using a ring rolling machine, with the deformation amount being ≥40%; the rolled titanium ring is shaped and subjected to recrystallization annealing heat treatment as a whole; after annealing, the inner wall of the titanium ring is turned using a CNC vertical lathe, waiting for use in subsequent hot-loading processes.
