AI Technical Summary
Existing graphite electrode processing and positioning structures only provide clamping force at two points, resulting in uneven force distribution and easy damage.
The system employs a combination structure of multiple hydraulic cylinders and positioning plates. The telescopic shafts of the hydraulic cylinders drive multiple positioning plates and rubber pads to clamp the graphite electrode, increasing the contact area and uniformity, while the rubber pads reduce friction.
This achieves uniform clamping of graphite electrodes, reduces the risk of damage, and improves processing stability.
