Abstract
The invention discloses applications of a spray cooling device in crankshaft oblique oil hole processing. The spray cooling means using compressed air to make cutting fluid atomize into two-phase mixed liquid, and the liquid is sprayed to a cutting zone in high speed through a nozzle close to the cutting zone, so as to play cooling, lubricating, and cleaning roles. Consumption amount of the cutting liquid is low, and residual trace liquid can be completely taken away by cuttings and does not need recycling, so working environment is clean. Using the device can improve cutting efficiency, improve precision of crankshaft oil holes, and reduce surface roughness of workpiece, prolong service life of cutters, and achieve optimal economical effect. A problem of drilling deep holes is solved by cooperation of the spray cooling device and a machine tool.
Description
Technical field
The invention discloses the application of a kind of spray cooling device in crankshaft oblique oil hole processing.
Background technology
The length of crankshaft oblique oil hole is longer, drilling depth is more than 20 times of bit diameter, the common fluted drill of usual employing or drill gun processing, if a large amount of heat in metal cuttings that fluted drill or drill gun produce when cutting can not be distributed in time, cutting fluid cooling effect is poor, chip removal is not smooth, not only make cutting wear reduce, and be difficult to the precision and the surface roughness that ensure oilhole, drill bit easily ruptures, processing cost is higher, and working (machining) efficiency is low.For improving stock-removing efficiency, improve the precision of crankshaft oil hole and reduce workpiece surface roughness, tool life, reach best economic effect, just must by reducing cutter and workpiece, rubbing between cutter and chip, take away cutting region internal cause material deformation in time and the method for heat that produces.Reach these objects, except by the exploitation cutter material of high-hardness high temperature resistant and the geometry of improvement of cutter, make outside the working (machining) efficiency of metal cutting improved rapidly, more to need to adopt spray cooling device to coordinate the difficulty solving drilling deep hole with lathe.
Summary of the invention
This programme is used for the application of spray cooling device in crankshaft oblique oil hole processing, so-called misting cooling utilizes compressed air to make atomized cutting fluid become two-phase mixtures liquid exactly, cutting region is ejected into via the nozzle at high speeds near cutting region, produce cooling, lubrication and cleaning effect, cutting fluid consumption is little, residual micro liquid can be all that cutting is taken away, and without the need to reclaiming, working environment cleans.
When spray cooling device is shown in that Figure of description 2 works, compressed air, through impurity such as water-separating gas filter filtering moisture, enters in tank for coolant by sub-fraction compressed air after magnetic valve, cooling fluid is forced into nozzle; Overwhelming majority compressed air mixes with cooling fluid to nozzle through compressed-air hose after pressure is adjusted to 0.32 ~ 0.35MPa by pressure regulator valve, is ejected into cutting region after atomization.
The middle and high fast bent axle of the main processing of my company, crankshaft oblique oil hole length is at 350mm ~ 510mm, for my company's bent axle, at crankshaft crank neck oblique surface machining inclined oil hole of air, specifically see Figure of description 1, crankshaft oblique oil hole coordinates spray cooling device to see Figure of description 3 at digital-control boring-milling machine, machining crankshafts inclined oil hole of air, utilizes spray cooling device can in the shortest time, with minimum cost, the inclined oil hole of air degree of error got out is extremely low, and smoothness is high and do not have burr.
Accompanying drawing explanation
fig. 1that spray cooling device is at crankshaft crank neck oblique surface machining inclined oil hole of air.
fig. 2it is high pressure cooling atomising device (WHP pulsed).
fig. 3that crankshaft oblique oil hole coordinates spray cooling device at digital-control boring-milling machine.
