Abstract

The invention discloses an oil-gas two-phase jet-type lubricating and cooling system, comprising a pressure gas supply device, a pressure oil supply device, a pure oil nozzle and N gas-oil nozzles, wherein the pressure gas supply device is connected with the gas-oil nozzles through an airflow pipeline; the pressure oil supply device is connected with both the pure oil nozzle and the gas-oil nozzles by an oil pipeline; each gas-oil nozzle comprises an oil jet pipe and an airflow jet pipe coaxially arranged outside the oil jet pipe; a shrinkage oil nozzle is arranged at the front end of the oil jet pipe; the gap between the internal wall of the airflow jet pipe and the external wall of the oil jet pipe forms an airflow passage; the front end of the airflow jet pipe is provided with an annular gas nozzle; oil-gas binary oil-in-gas concentric jet is formed by the continuous column oil jet sprayed from the shrinkage oil nozzle and the annular gas jet sprayed from the annular gas nozzle; the oil is not mixed with the gas; when the system is working, oil molecules on the surface of headed materials and the contact surface of mould and the headed materials have stronger permeability so as to lubricate and cool more sufficiently.

Description

technical field [0001] The invention relates to a lubricating and cooling technology applied in the metal cold heading process, in particular to an oil-air two-phase jet lubricating and cooling system for a multi-station automatic cold heading machine. Background technique [0002] The metal cold heading process is a non-cutting process that uses the cold plastic deformation characteristics of metals. The multi-station automatic cold heading machine is a kind of metal cold plastic forming processing equipment. The degree of deformation of each upsetting station is different during operation, so the real-time temperature effect of each upsetting station is different. [0003] Since the plastic deformation process of metal is carried out under high pressure, the contact surface between the multi-station automatic cold heading machine and the metal will continue to increase, so that the contact conditions between the multi-station automatic cold heading machine and the metal ...
