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

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] The present invention proposes a lubricating and cooling jet nozzle for a multi-station automatic cold heading machine, such as figure 1 and figure 2 As shown, it includes an oil injection pipe 1 and an air flow injection pipe 2 coaxially sleeved outside the oil injection pipe 1. The tail end of the air flow injection pipe 2 is sealed and connected with the tail of the oil injection pipe 1. The oil injection pipe The tail end of 1 is provided with an oil inlet 11, the front end of the oil injection pipe 1 is integrally provided with a constricted oil nozzle 12 for spraying continuous cylindrical oil jets, and the tail of the air flow injection pipe 2 is provided with an air inlet 21 The inner diameter of the air jet tube 2 is greater than the outer diameter of the oil jet tube 1, and the annular space between the inner peripheral wall...

The invention discloses a lubricating and cooling jet nozzle for a multi-station automatic cold heading machine. There is an oil inlet, the front end of the oil injection pipe is provided with a retractable oil nozzle, the tail of the air flow injection pipe is provided with an air inlet, and the annular gap between the inner peripheral wall of the air flow injection pipe and the outer peripheral wall of the oil injection pipe is formed. The air flow channel, the front end of the air jet pipe is provided with an annular air jet, the continuous columnar oil jet ejected from the contracting oil nozzle and the annular air jet ejected from the annular air jet form an oil-gas binary oil-in-gas concentric jet, and the oil The air and gas do not mix with each other, so that the low-pressure oil under the high-speed airflow is shot towards the surface of the upsetting material and the contact surface between the module and the upsetting material, which can make the contact between the surface of the upsetting material and the mold and the upsetting material The oil molecules on the surface are more permeable, so that the lubrication and cooling are more complete and the effect is 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. Du...
