AI Technical Summary

Technical Problem

The existing technology is difficult to ensure sequential cutting when cutting multi-layer reverse-wound flexible shafts, resulting in the inner layer breaking first and then collapsing and uneven incisions. In addition, the cutting process is not stable enough, which easily leads to inter-layer dislocation and a sudden drop in friction.

Method used

The circular saw blade revolves around the axis and feeds radially in a circular cutting method. Combined with the double-layer positioning structure of the clamping module, the cutting depth is monitored by sensors and the blade feed is adjusted to ensure layer-by-layer cutting. The reverse torque is used to form a pre-tightening force to suppress loosening between layers.

Benefits of technology

It achieves stable and precise cutting of the flexible shaft, avoids the collapse of the inner layer and the dislocation between layers, improves the stability and production efficiency of the cutting process, and reduces manual intervention and equipment failure.

Abstract

The invention relates to the technical field of flexible shaft cutting, and discloses a flexible shaft machining traction cutting assembly which comprises a cutting module, traction modules are installed on the two sides of the cutting module, and the cutting module comprises a circular saw blade. The circular saw blade realizes revolution motion around the axis of the flexible shaft main body and radial feed motion towards the axis of the flexible shaft main body through an external driving device, and the revolution motion of the circular saw blade around the axis of the flexible shaft main body is combined with the radial feed motion, so that each layer of the flexible shaft is sequentially and annularly cut from the outer layer to the inner layer; compared with traditional linear cutting which is difficult to ensure the cutting sequence, the structure ensures that a cutter always cuts in layer by layer from the outermost layer by utilizing an annular track formed by revolution, the problem of disintegration caused by first breaking of the inner layer is avoided, the sequential cutting mode is matched with the design that the annular cutting direction is opposite to the winding direction of each layer of the flexible shaft, and the cutting efficiency is improved. Reverse torque is generated in the cutting process and forms pre-tightening force with winding tension of the uncut portion of the inner layer, and the loosening tendency between steel wire layers is effectively restrained.
