Machine tool cutter temperature control device

Abstract

The invention discloses a machine tool cutter temperature control device capable of replacing cutting fluid. The machine tool cutter temperature control device is characterized by comprising a cold conduction block, a cooling semiconductor, a radiator, a rubber gasket, a movable clamp, a temperature sensor, an adjustable sleeve and a controller assembly, wherein the cold conduction block is in contact with a cutter handle through heat conduction silicone grease; cutter waste heat is absorbed through the Peltier effect of the cooling semiconductor; and the waste heat is transmitted to the radiator through a heat conduction plate so as to be dissipated. A temperature monitoring module monitors the contact temperature of a cutter and a workpiece in real time through an infrared radiation sensor and inputs a signal to the controller assembly, and the controller assembly adjusts the current passing through the cooling semiconductor according to the preset temperature and the real-time temperature so as to control refrigeration power. According to the machine tool cutter temperature control device provided by the invention, no cutting fluid is needed, no waste liquid is discharged, no noise is generated, continuous work can be achieved, the power is controllable, high-precision temperature control can be achieved, and the cutter and a cutting material can be reversely heated under the special process requirement.

Description

technical field [0001] The invention relates to a temperature control device for a machine tool which replaces cutting fluid. Background technique [0002] In machining and manufacturing, when metal is cut, the work done by the shear deformation of the chip and the work done by the front and rear friction of the tool are all converted into heat, which is called cutting heat. Cutting heat affects tool life and cutting quality. Cutting fluid is widely used to cool workpieces, resulting in a large amount of waste cutting fluid. Traditional cutting waste cooling cutting fluid pollutes the environment and is not conducive to clean production. Cutting fluid wastewater contains a large amount of emulsified oil, additives such as surfactants, corrosion inhibitors, and defoamers, as well as impurities such as waste oil, dust, and metal shavings, and must be strictly treated before being discharged. The cutting waste liquid is directly discharged into the natural water body, which ...
