Lubricating and cooling jet nozzle for multi-station automatic cold header

Abstract

The invention discloses a lubricating and cooling jet nozzle for a multi-station automatic cold header, comprising an oil fluid jet pipe and an airflow jet pipe coaxially sleeved out of the oil fluid jet pipe; wherein an oil inlet is arranged at the tail end of the oil fluid jet pipe; a shrinkable oil fluid nozzle is arranged at the front end of the oil fluid jet pipe; an air inlet is arranged at the tail part of the airflow jet pipe; an annular clearance between the inner peripheral wall of the airflow jet pipe and the outer peripheral wall of the oil fluid jet pipe forms an airflow channel; an annular air nozzle is arranged at the front end of the airflow jet pipe; the successive cylindrical oil jet jetted from the shrinkable oil fluid nozzle and the annular airflow jetted from the annular air nozzle form oil-air binary air-in-oil concentric jet flow, the oil and the air are not mixed, so that the low-pressure oil fluid under the holding of high-speed airflow is jetted to the surface of headed material and contact surface between the mold and the headed material during operation, the penetrability of the oil fluid molecule on the surface of the headed material and the contact surface between the mold and the headed material is higher, so that the lubricating and cooling effects are more sufficient, and the effects are maximized.

Description

technical field [0001] The invention relates to a lubricating and cooling equipment for metal cold heading technology, in particular to a lubricating and cooling jet nozzle 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 will continue to change.

Problems solved by technology

Therefore, a large amount of oil mist will be generated during the plastic deformation of the metal, and these oil mist are essentially three-phase smoke, which is harmful to the human body if inhaled for a long time, and will pollute the workplace environment
