Description

Technical Field

[0001] The utility model belongs to the technical field of rolling cutters, in particular to an impact-resistant rolling cutter. Background Art

[0002] The rolling method refers to the process in which, under the action of a rolling tool, external force induces strong plastic deformation on the surface of a metal material, activates non-equilibrium defects such as dislocations and stacking faults inside the crystal through the plastic flow of the near-surface material, and gradually cuts small-angle large grain boundaries into large-angle small grain boundaries through crystallographic movements such as dislocation proliferation, twinning, and slip, thereby achieving the division and refinement of large grains on the surface into ultrafine grains or nanocrystals.

[0003] When the existing rolling tools are actually used to process the workpiece, the rolling tools come into contact with the workpiece and are subjected to a large instantaneous impact force. At this time, the rolling tools are easily deformed or even damaged, and the impact resistance is poor. The staff needs to disassemble and replace the rolling tools regularly. However, the disassembly and assembly of the rolling tools by the staff is currently cumbersome and the disassembly and assembly efficiency is not good. For this reason, we propose an impact-resistant rolling tool to solve the existing problems. Utility Model Content
