AI Technical Summary

Technical Problem

Existing wire EDM machines suffer from low fixture positioning accuracy, time-consuming manual calibration, and the clamping pressure can easily damage the workpiece or cause displacement. The lack of effective cooling during processing can lead to thermal deformation, and the cumbersome disassembly and assembly of fixtures affects maintenance efficiency, making them unable to meet the needs of high-precision mold processing.

Method used

It adopts adjustable positioning components, adaptive clamping components, real-time positioning detection components, quick disassembly and assembly components, and cooling components to achieve precise positioning, adaptive clamping, real-time monitoring and convenient maintenance. The laser displacement sensor detects the workpiece position, the pressure sensor adjusts the clamping force, the serpentine cooling channel cools down the workpiece, and the quick disassembly and assembly structure simplifies the maintenance process.

Benefits of technology

It achieves high-precision mold processing with high positioning accuracy and stability, avoids workpiece damage and thermal deformation, improves processing efficiency and equipment operation and maintenance efficiency, and meets the processing requirements of high-precision molds.
