Problems solved by technology

Up to now, when using external cooling gas cooling equipment, the operator usually manually adjusts the distance between the nozzle and the cutting area through trial processing or experience. This method is inefficient and difficult to parameterize and quantitatively adjust, and the cutting cooling effect cannot be optimized. , it is also difficult to obtain high-quality part surface

Abstract

The invention discloses a parametric control system and method for metal cutting cooling gas jet. The system consists of a nozzle body, a voltage-stabilizing and constant-value valve, a mass flow controller, an infrared temperature sensor, an electric sliding table and a PID controller. composition. The electric sliding table is fixed at the appropriate position of the machine tool, and the infrared temperature sensor is used to monitor the temperature of a certain point on the workpiece in real time to reflect the heat exchange effect; when the environmental factors, gas supply factors, process factors, machine tool factors, etc. The established parameterized model compares the temperature measurement value with the expected value by the PID controller to realize the temperature feedback control. In the invention, the cooling gas before entering the nozzle is regulated by introducing a constant value valve, and a mass flow controller is introduced to adjust the instantaneous mass flow of the cooling gas at the inlet of the nozzle according to different cutting environments and conditions.

Description

technical field [0001] The present invention relates to the field of automatic regulation and control of optimal cooling of the cutting zone during the metal cutting process; specifically, it is a parameterized control system for metal cutting cooling gas jets and parameterization of the cooling gas inside the nozzle Modeling and regulation system and method, so as to ensure that the temperature of a certain point of the workpiece is controllable during cutting, so that the temperature reaches the expected temperature according to the process requirements, and indirectly evaluate the cooling effect, so as to realize the closed-loop feedback control and automation of temperature adjust. Background technique [0002] During metal cutting, it is necessary to cool and lubricate the cutting tool and cutting area to achieve the purpose of prolonging tool life, ensuring processing quality, and improving processing efficiency. [0003] According to different cooling methods, metal ...
