When cutting liquid, very big noise can be generated, this defect limits the application of low-temperature trace lubrication technology.
Summary of the invention
The purpose of the utility model patent is in view of the deficiencies of the prior art, it is rotatably low to provide a kind of low-temperature trace lubrication
Warm injection apparatus.The device for extremely low temperature cold wind in transmission process temperature increase, to will be with oil liquid mixing cold wind
Cool down and keeps the temperature, compensation temperature loss；Spray angle can also be adjusted according to the variation of cutting zone.
The purpose of this utility model is achieved through the following technical solutions:
The utility model technical scheme applied to solve the technical problem is: one kind being suitable for low-temperature trace lubrication cutting and adds
The rotatable cryogenic spray device of work.Two class features of low temperature and micro lubricating are combined, after the gas of high speed and high pressure will mix
Cutting oil and coolant liquid atomization be small spraying particles in tool surface, play instant cooling down, inhibit built-up edge existing
As tool life improves the quality of machined surface.The gas of high pressure can take away a large amount of chip, reduce useless
Consider recycling problem to be worth doing.Furthermore atomized liquid can significantly reduce sticking phenomenon in cutting process to chip reducing temperature twice.
The utility model has the beneficial effects that the utility model is a kind of to turn suitable for low-temperature trace lubrication machining
Dynamic cryogenic spray device.Cold wind injector and heat preservation sleeve cooperation are double-layer structure, constitute low temperature path, effect is will be low
Warm solution injection low temperature path cools down again to cold wind, compensates the cold wind temperature of loss, cold wind jet port and internal-mixing device
Interior mixed chamber communicates, and is sprayed onto cutting zone with cutting after oily coolant liquid is sufficiently mixed.Its external adjustable injection that is connected with bracket
The spray angle of device is given full play to it and is sprayed in different cutting regions using different angle, reaches accurate cooling.It is answered
It is wide with range, it is at low cost, it is easily installed, easy to operate and safe, oil-spray film nebulization efficiency is high, and spray distribution is uniform, inhibits product
Bits knurl phenomenon, tool life improve the quality of machined surface.Operator's health is also helped, to ring
Border pollution is few.
