AI Technical Summary
Existing pipe cutting machines have complex structures, occupy a large space, have poor cutting accuracy, low operational reliability, and are difficult to fully automate.
It adopts a differential feed structure. Through the cooperation of the differential generation module and the control unit, the differential rotation of the first differential component and the second differential component is realized, which drives the linkage feed component to perform differential feed or retraction. Combined with the clamping module and mechanical connection method, the mechanical connection method is used to replace the signal or electronic connection.
It achieves higher cutting precision and stability, reduces failure rate, simplifies equipment structure, extends service life and reduces maintenance costs.
