Inner-cooling rolling cutter special for variable-angle low-temperature lubrication

Abstract

The invention discloses an inner-cooling rolling cutter special for variable-angle low-temperature lubrication, which comprises a cutter handle, a rotatable tool bit and a medium conveying pipeline; the rotatable tool bit comprises a base, a rolling head and a ball; the bottom end of the base is installed on the cutter handle, and a medium input port connected with the medium conveying pipeline is arranged at the top of the base; the rolling head is detachably mounted on the front end face of the base, and a plurality of spray holes are arranged on the front end face of the base in the circumferential direction of the rolling head; the medium conveying pipeline is communicated with the spray holes through a medium flowing channel; the ball is installed at the end, away from the base, of the rolling head; the medium conveying pipeline is used for conveying a cooling and lubricating medium; and the base has a rotating state and a locking state. The inner-cooling rolling tool provided by the invention can achieve low-temperature rolling of the surface layer of a metal material, has the advantages of being easy to operate and convenient to install, and solves the problems that an existing low-temperature rolling device is low in machining efficiency and precision.

Description

technical field [0001] The invention relates to the technical field of metal rolling, in particular to a special inner cooling rolling cutter for variable angle low temperature lubrication. Background technique [0002] Rolling is a non-cutting plastic processing method. The rolling tool is used to apply a certain pressure on the surface of the workpiece, so that the metal on the surface of the workpiece produces plastic flow, and the material at the peak position of the surface is filled into the concave trough, making the surface of the workpiece rough. At the same time, due to the plastic deformation of the rolled surface metal, the surface structure is hardened by cold work, forming a dense fibrous shape, and forming a residual stress layer, increasing the hardness and strength, thereby improving the fatigue resistance of the workpiece surface. However, a single rolling strengthening treatment has little effect on the introduction of residual compressive stress on the su...
