AI Technical Summary

Technical Problem

The existing roller layout of the circular cutting machine has rationality issues, resulting in limited cutting height or complex structure, large space occupation, and high cost.

Method used

The design employs an isosceles triangular cutting fixing plate and a double guide column structure to reduce the number of rollers. The tension control and cutting angle adjustment of the circumferential tangent are achieved through the adjustable height and angle of the drive and driven rollers.

Benefits of technology

This design achieves a compact structure for the circular wire cutting machine, reduces the weight of the fixed plate, expands the height applicability of the workpiece being cut, and optimizes the cutting posture.

Abstract

The ring cutting mechanism of the ring cutting machine comprises a cutting fixed plate, a driving roller, a driven roller, a tension adjusting roller, a vertical guide column and a lifting driving mechanism, wherein the cutting fixed plate is in the shape of an isosceles triangle and is provided with an upwardly recessed notch groove on the bottom side; the driving roller and the driven roller are installed at positions on both sides of the bottom side of the notch groove of the cutting fixed plate, the tension adjusting roller is installed at a top corner of the cutting fixed plate, a ring cutting line is arranged around the driving roller, the driven roller and the tension adjusting roller; and the two bottom corners of the cutting fixed plate are connected with the vertical guide column through sliding devices respectively. The triangular structure layout can greatly reduce the number of rollers and the self weight of the cutting fixed plate, the structure is more compact, the use effect is better, the driven roller is arranged to be movable up and down, the cutting angle of the cutting line can be adjusted, and the cutting posture of the workpiece can be adjusted.
