A Three-Point Cylindrical Rolling Knife

Abstract

The invention discloses a three-point outer circle rolling cutter. The three-point outer circle rolling cutter comprises a handle, wherein a main frame is mounted on the handle, the upper part of the main frame is provided with an upper rolling cutter group, the upper rolling cutter group is mounted on a telescoping mechanism capable of moving up and down, the lower end of the main frame is provided with two lower rolling cutter groups, and the two lower rolling cutter groups are symmetrically arranged around the axis of the upper rolling cutter; the lower part of the main frame is symmetrically provided with first processing locating holes and second processing locating holes, the first processing locating holes are arranged adjacently while the second processing locating holes are in the outer sides of the corresponding first processing locating holes, and the lower rolling cutters are respectively mounted in the corresponding first processing locating holes or second processing locating holes. The three-point outer circle rolling cutter has the advantages that the structure is simple, the lower rolling cutter groups are selected to be mounted in positions according to the size of a workpiece when the cutter is used, so that the rolling cutter has very wide processing range; when processing the workpiece, the upper rolling cutter group and the two lower rolling cutter groups simultaneously contact the surface of the workpiece to form three-point rolling, and thus, processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a three-point cylindrical rolling tool. Background technique [0002] Machine tool processing refers to the processing of raw materials with machine tools. Machine tool processing can be divided into ordinary lathe processing and CNC lathe processing according to different machine tools. With the continuous development of machine tool processing technology, CNC lathes have gradually replaced ordinary lathes. The use of CNC lathe processing not only improves the production effect of parts and products, but also improves the precision of processing to meet the processing needs of fine processing and precision parts. [0003] Rolling knife is a mechanical non-cutting plastic processing method that uses the principle of mechanical extrusion to obtain a mirror-like metal surface. The rolling knife can use the plastic deformation of the metal at room temperature to flatten th...

AI Technical Summary

Problems solved by technology

The existing outer circle rolling cutter adopts the uniform distribution of rolling heads on the inner wall of the circular hob head to realize rolling processing, but the adjustment range of the rolling cutter with this structure is small, and the processing range is narrow, so it is often necessary to prepare multiple The size of the rolling knife to meet the needs of processing

Another method of external rolling processing is to use a rolling knife with a single rolling head, but its processing efficiency is low, and the single rolling head is likely to cause uneven force, which affects the processing accuracy
