Problems solved by technology
[0002] At present, in the field of mechanical processing, the machining process is developing towards high speed and large depth. Under this development trend, more mechanical energy is converted into heat energy during the processing process, which greatly increases the heat generated by the contact surface between the tool and the workpiece. If the heat cannot be transferred out in time, the temperature of the cutting edge of the tool and the workpiece processing surface will rise sharply, resulting in tool damage and workpiece damage.
In the prior art, the method of spraying coolant to the processing area is usually used to take away the heat generated during the processing, but the above-mentioned cooling method has the following defects: 1. With the increase of the processing depth and complexity of the workpiece, the coolant The injection efficiency is reduced and the injection structure is becoming more and more complex; 2. The extensive use of coolant will increase the cost and easily cause adverse effects on the environment

The invention discloses a self-cooling vertical cutter which comprises a cutter body. A plurality of sealed spiral cavities which wind each other are arranged in the cutter body. One end of each cavity extends to the cutting edge position of the cutter body, and the other end of each cavity extends to the tail portion of the cutter body. Low-boiling-point heat exchange liquid is filled in all the cavities, the volume of the low-boiling-point heat exchange liquid in the cavities is 0.2-0.3 that of the cavities, and a plurality of grooves distributed in the extending direction of the cavities are arranged on the inner wall of each cavity. The self-cooling vertical cutter is good in the cooling effect and environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of machining equipment, in particular to a self-cooling vertical cutter. Background technique [0002] At present, in the field of mechanical processing, the machining process is developing towards high speed and large depth. Under this development trend, more mechanical energy is converted into heat energy during the processing process, which greatly increases the heat generated by the contact surface between the tool and the workpiece. If the heat cannot be transferred out in time, it will cause a sharp rise in the temperature of the cutting edge of the tool and the processed surface of the workpiece, resulting in damage to the tool and the workpiece. In the prior art, the method of spraying coolant to the processing area is usually used to take away the heat generated during the processing, but the above-mentioned cooling method has the following defects: 1. With the increase of the processing depth and c...
