Description

Technical Field

[0001] The invention relates to the technical field of tool quenching equipment, in particular to a quenching equipment for numerical control tool processing. Background Art

[0002] CNC tools need to be quenched during processing. First, the CNC tools are heated and then quenched with water or other liquids. Existing quenching methods are mostly divided into two operating modes. One is to directly flush the heated CNC tools with a water pipe, and the other is to place them directly in a pool of water for quenching. When flushing with water, due to the fast cooling speed, large thermal stress may be generated inside the tool. If these stresses exceed the fracture strength of the material, they may cause cracks or even breakage in the tool. Water flushing will also cause inconsistent cooling speeds on the surface and inside of the tool, resulting in uneven hardness. This hardness difference may affect the cutting performance and service life of the tool, and may also cause the tool to deform. , surface quality problems. When placing the CNC tool directly in the water pool, manual operation is generally required, and the placement speed needs to be precisely controlled. If the quantity is large, it will cause mental and physical fatigue to the operator. In addition, the surrounding temperature is high during heating, which will cause the operator to be baked by the heat. Moreover, burns may occur during the operation due to heat or accidental touch. More importantly, the CNC tool is generally held by hand during heating. During the operation, if the operator accidentally touches it, the CNC tool will come into contact with the heating coil, causing damage to the CNC tool and the heating coil.
