AI Technical Summary
After prolonged continuous operation, existing hot cutting machines suffer from blade wear, leading to decreased cutting accuracy. Unstable temperatures of the electric heating elements also affect cutting quality, making it difficult to meet the precision and stability requirements of electronic component processing.
A linear displacement mechanism is adopted, which coordinates the flat-edge upper cutting tool with the carrier table and the upper tool holder. The movement of the carrier table and the upper tool holder is controlled by the first and second linear displacement mechanisms. Combined with the lifting drive unit, the independent horizontal and vertical movement of the upper cutting tool is realized. Limiting blocks and limiting grooves are used to ensure that the cutting tool and the workpiece are closely fitted. A speed control mechanism is used to stabilize heat transfer.
It improves cutting accuracy and processing stability, reduces quality fluctuations caused by displacement deviation, and results in smooth and flat workpiece cutting edges, thereby improving production efficiency and product quality.
