Example 3

[0061] Based on the above embodiment, the difference between the present embodiment is that: Figures 4 to 8As shown, a U-shaped bracket 3075 is installed on the synchronous bracket 3076. The U-shaped bracket 3075 passes through the through slot opened on the cantilever 307 and is sleeved on both sides of the rocker plate 3071. A tie rod 3074 is installed inside the U-shaped bracket 3075. A positioning groove 3073 is opened on the rocker plate 3071, and the tie rod 3074 is slidably disposed in the positioning groove 3073.

A torsion spring 3092 is snapped between the rotation center of the push plate 309 and the positioning seat 3091. A fixing plate 308 is installed on the side wall of the sleeve 305, and a straight plate 3081 is installed on the fixing plate 308. Both ends of the straight plate 3081 are equipped with protrusions 3082, and the two protrusions 3082 are located on both sides of the insertion rod 3051. 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. The push plate 309 is tilted as a whole, and the push plate 309 slides relative to the protrusion 3082, which makes the distance between the protrusion 3082 and the rotation center of the push plate 309 get closer and closer. At this time, the push plate 309 is pushed to rotate a larger angle, and the torsion spring 3092 is twisted at the same time. The torsion spring 3092 facilitates the later reset. Finally, when the push plate 309 rotates to a certain angle, the outermost part of the push plate 309 can fix the side wall of the semi-finished titanium ring 500.

Welding operations are performed through the plasma automatic welding machine body 401, which can slide on the guide rail 4022 of the flat plate 4021, thereby allowing welding operations to be performed at different positions.

[0064] The implementation principle of the method for preparing a cathode roller titanium ring by welding and forming in this embodiment is as follows:

[0065] First, the TA1 titanium plate raw material is beveled at both ends, and the four-roller plate rolling machine is used to roll and butt joint.

[0068] Next, the operator starts the driving motor 2011, which drives the screw shaft 201 to rotate. At this time, the guide slider 2014 on the screw shaft 201 can slide along the guide slider 2014, and the guide slider 2014 penetrates the partition plate 2013. The fixed seat 301 on the top of the guide slider 2014 starts to move synchronously to the semi-finished titanium ring 500.

[0069] When the bearing plate 3021 on the side wall of the fixed seat 301 contacts and extrudes the semi-finished titanium ring 500, the fixed seat 301 and the top plate 202 can fix the semi-finished titanium ring 500 in the axial direction. During the extrusion process, the bearing plate 3021 and the pressure rod 302 are extruded, which can move the pressure rod 302 to the inside of the inner cavity 3011 of the fixed seat 301. The limiting plate 3022 mainly plays a limiting role. When the pressure rod 302 slides, the synchronous plate 303 on the pressure rod 302 can slide synchronously. The synchronous plate 303 compresses the return spring 3033 in the inner cavity, which facilitates the later reset.

[0070] When the synchronous plate 303 slides, the mounting seat 3031 on the side wall of the synchronous plate 303 slides synchronously. The slide rod 3032 on the mounting seat 3031 slides in the strip-shaped groove 3041 of the swing arm 304, thereby driving the swing arm 304 to swing as a whole. The swing arm 304 drives the sleeve 305 to swing as a whole through the synchronous shaft 3042.

[0071] When the swing arm 304 rotates through the synchronous shaft 3042, the sleeve 305 can drive the inserted inserting rod 3051 to swing, and finally make the inserting rod 3051 and the top pressing plate 3052 rotate into the semi-finished titanium ring 500 (initial position is not in the semi-finished titanium ring 500, and the purpose is to facilitate the vertical placement of the semi-finished titanium ring 500). During the rotation of the inserting rod 3051, the guide rod 3053 on the side wall of the inserting rod 3051 first slides in the arc-shaped groove 3061, and when sliding from the arc-shaped groove 3061 to the straight groove 3062, the entire guide rod 3053 has a tendency to slide outward, thereby driving the inserting rod 3051 to slide outward relative to the sleeve 305, and thereby driving the top pressing plate 3052 to slide outward, so as to extrude the top inner cavity of the semi-finished titanium ring 500.

[0072] And when the sleeve 305 rotates, the sleeve 305 can drive the cantilever 307 and the flap 3071 on the side wall to rotate to the lower part inner cavity of the semi-finished titanium ring 500, and when the inserting rod 3051 slides, the inserting rod 3051 can drive the synchronous support 3076 to slide outward, and the synchronous support 3076 at this time slides in the through groove of the cantilever 307, the U-shaped support 3075 and the pull rod 3074 at the bottom of the synchronous support 3076 can slide synchronously, the pull rod 3074 at this time slides in the positioning sliding groove 3073 of the flap 3071, and finally can drive the flap 3071 to rotate, and the flap 3071 rotates the bottom pressing plate 3072 at the end downward to extrude and fix the bottom of the semi-finished titanium ring 500, and further achieves the purpose of positioning.

[0073] And when the inserting rod 3051 moves, the positioning seat 3091 on the side wall of the inserting rod 3051 drives the push plate 309 to move, and the push plate 309 as a whole is inclined, the push plate 309 is slidable relative to the protrusion 3082, and the distance between the protrusion 3082 and the rotation center of the push plate 309 becomes closer and closer, at this time, the push plate 309 rotates a larger angle, and at this time, the torsional spring 3092 is twisted synchronously, and the torsional spring 3092 facilitates the later reset, and 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 at this time.

[0074] The present application can fix the axial and radial directions of the semi-finished titanium ring 500 through one driving source, is simple to operate, and has lower manufacturing cost.

[0075] After the fixing is completed, the operator can perform welding operation through the plasma automatic welding special machine body 401, and the plasma automatic welding special machine body 401 can slide on the guide rail 4022 of the flat plate 4021, and thus welding operation can be performed at different positions.

[0076] Finally, the welded titanium ring is placed in an electric heat treatment furnace for high-temperature homogenization heat treatment; a ring rolling machine is used to roll the titanium ring after the heat treatment, and the deformation is ≥40%; the titanium ring after rolling is corrected, and the whole is subjected to recrystallization annealing heat treatment; after annealing, the inner wall of the titanium ring is turned by a numerical control vertical lathe, and is used in subsequent hot charging processes.
