Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elimination devices, in particular to an elimination device for the stress of CBN tools. Background Technique
[0002] CBN tools, namely cubic boron nitride tools, are superhard material tools. CBN has the advantages of high temperature resistance, high hardness, high inertness, etc., and has been increasingly used in rough and finish machining of high-hard cast iron, ordinary cast iron, and hardened steel. Due to manufacturing processes, internal stress is inevitably generated in CBN tools. The internal stress in CBN tools will cause the amplification of microdefects inside the polycrystal, and microcracks will expand into cracks under the action of stress, which will cause the tool to chip or wear rapidly during use. Therefore, in order to improve the service life of CBN tools.
[0003] By means of vibration aging, the vector of the residual internal stress and the additional vibration stress inside the tool can be made to exceed the yield strength of the material, causing the tool to undergo a small amount of plastic deformation, so that the internal stress of the tool can be relaxed and reduced, and the service life of the tool can be improved. In order to improve efficiency, existing stress elimination devices in the form of vibration will vibrate a large batch of tools simultaneously. However, due to collisions between tools during the vibration process, the tools will be worn, thus reducing the service life of the tools.
[0004] Therefore, in view of the above problems, we propose an elimination device for the stress of CBN tools. Content of the Utility Model
