The knife seat lifting drive 205 is used to control the rise or fall of the ultrasonic vibration knife head 206. A detachable ultrasonic knife is provided on the ultrasonic vibration knife head 206.

[0037] In this embodiment, the guide knife group includes a guide knife seat 208, a steering drive 209 and a guide partition 210. The guide knife seat 208 is installed on the knife holder 204 through a guide lifting drive 207. The guide lifting drive 207 can drive the guide knife seat 208 to rise or fall; the steering drive 209 is fixedly installed on the guide knife seat 208, and the steering drive 209 can drive the guide partition 210 to rotate.

[0038] In this embodiment, a material guide groove 212 and a material blocking plate 211 are disposed on the guide partition plate 210 .

[0039] Through the above design scheme, the ultrasonic vibration cutter head 206 can improve the sharpness of the tool so that it can quickly cut off the pouring mouth of the steering wheel. After processing the larger pouring mouth, the ultrasonic vibration cutter head 206 is lowered, and the guide baffle 210 is rotated to make the guide tool 213 close to the edge of the steering wheel. As the steering wheel rotates, the flash on the edge of the steering wheel can be automatically cut off. The cut-off flash will be guided away by the guide groove 212 and the baffle plate 211 to avoid the accumulation of flash and affect the subsequent processing efficiency.

[0040] In this embodiment, the locking mechanism 3 includes a fastening assembly and a pouring port clamping assembly. The fastening assembly is used to lock the steering wheel on the bracket body 1, and the pouring port clamping assembly is used to clamp the pouring port of the steering wheel.
