Description

The invention relates to the field of high-speed machining of parts on CNC equipment, in particular, to cutting tool cooling systems.

A device for precision machining of parts on CNC equipment is known [RF Patent No. 2280540, class. B23B 25/06, 2006 (analog)]. The disadvantage of this device is the high technical complexity associated with the need to cool the cutter due to the supply of cutting fluid, as well as the complexity of the design of the device.

Closest to the invention in technical essence is a cooling device for a cutting tool [RF Patent No. 2470757, cl. B23B 11/10, 2013 (prototype)]. The main disadvantage of the device is that when the cutter is cooled, a controlled current generator is used, which increases the energy consumption for the operation of the device.

The technical result is to reduce energy consumption when cooling the cutting part of the cutter due to the Thompson effect.

The technical problem of the invention is solved in that in the energy-saving cooling device of the cutting tool containing the part, front headstock, tailstock, cutter, consisting of a cutting part, a special plate with a thermocouple and holder, a tool holder, actuators of CNC equipment, a current lead and a computer, heat sinks are added pipes, thermoelectric sections, battery.

Heat is removed from the cutting zone by means of heat pipes to the energy-saving cooling device of the cutting tool. Between the heat pipes are installed thermoelectric sections, which are connected to each other by means of conductors. The current flows through the current leads to the battery and then to a special plate with a thermocouple.

Figure 1 presents a diagram of an energy-saving cooling device for a cutting tool.

An energy-saving cutting tool cooling device contains a part 1, a front headstock 2, a tailstock 3, a cutter consisting of a cutting part 4, a special plate with a thermocouple 5 and a holder 6, a tool holder 7, actuators of CNC equipment 8, heat pipes 9, thermoelectric sections 10, battery 11, current lead 12 and computer 13.

The connections in the energy-saving cooling device of the cutting tool are located as follows: the output of the computer 13 is connected to the actuators of the CNC equipment 8, which move the tool holder 7 with a cutter fixed in it, consisting of a holder 6, a special plate with a thermocouple 5 and a cutting part 4. Special input plate with a thermocouple 5 using current leads 12 is connected to the output of the battery 11. The input of the battery 11 is connected to the output of thermoelectric sections 10 installed between the heat pipes 9, located above the workpiece 1, mounted in the front headstock 2 and tailstock 3.

Energy-saving cooling device of the cutting tool operates as follows. When part 1 is heated in the cutting zone, the outgoing warm air exits through the heat pipes 9, thermoelectric sections 10 are installed between the heat pipes 9, in which warm air (temperature in the cutting zone ≈250 ° C) heats one end of the junctions of the thermoelectric section 10 operating based on the Thompson effect, and cold air (workshop temperature ≈22 ° C) cools the other ends of the junctions of the thermoelectric section 10. Thermoelectric power is obtained. As a result, the generated current flows through the current lead to the battery 11. From the battery 11, the current through the current lead 12 enters a special plate with a thermocouple 5. In this case, the cutting part of the cutter 4 is cooled without additional energy consumption, since the energy is generated by increasing the temperature in the zone cutting.

Thus, the proposed energy-saving device for cooling the cutting tool can reduce power consumption when cooling the cutter.
