A kind of device of cutting element cooling fluid of bulletin makes cooling fluid be fed to cutting region under pressure, this device comprises the housing of its top with the lid sealing, this covers a cutter shaft that cutting tool is arranged that seal wherein is being set, and this cutter shaft just passes from this hole.(see partly the 172nd～176 page of в of Moscow publication NO12 " higher education circular " machine-building in 1969. м. Я р о с л а в ц e в, в. в. " machining in the high static pressure lubrication cooling medium " of С а о e л ь н ч к о в work).Carry cooling fluid with required pressure with pump in the housing chamber, workpiece to be processed just is installed in this housing.Because the pressure in the housing is very high, cooling fluid just directly has been added on the cutting edge of cutter, and has improved its stability significantly.
But the way that part in addition to be processed is installed in the airtight housing makes in the removal sealing, mounts and dismounts processed cooling, will lose a lot of times when being full of this housing and sealing this housing with cooling fluid, thereby the productivity ratio of greatly reducing.Can make device expensive and complicated and possess high-pressure pump.
Deutsche Bundespatent discloses a kind of device that cooling fluid is supplied to cutting element for No. 747139, this device has a housing that has the hole of using for the cutter shaft of cutting element, one is installed in interact seal on the housing in zone of cutting element and processed in addition part, and some import metalworking coolant and derive conduit and the window that the scrap fallaway that communicates with the housing inner chamber is used of housing.Make bell housing with itself bottom supporting on the surface of workpiece to be machined.
Cooling fluid is imported enclosure interior by being used to import pipe joint cooling fluid, that be screwed in the coolant system, be used for scrap fallaway but the window that also can be used for discharging cooling fluid is opened at the position that is higher than pipe joint.Such cooling fluid column produces a static pressure, and under this static pressure effect, cooling fluid flows in the processed hole and increased the stability of cutting tool.
But, because the cooling fluid liquid-column height decision that housing blow-by and pressure are only limited by shell dimension, so above-mentioned the sort of device can not produce sufficiently high coolant pressure, will make the drilling efficiency reduction like this.This device can only be limited to vertical drilling system use in addition.
Task of the present invention is to set up the device of the supply of cooland to cutting tools with following characteristics.This device just can be set up quite high cooling fluid static pressure without high-pressure pump, and it can be used in the vertical and horizontal system of the difform workpiece of processing any degree of depth.
Can finish the present invention regulation task provide the device of cooling fluid to comprise a housing that has the hole that is used to pass the cutting element cutter shaft to cutting element, a seal that is contained in the cutting element processing work zone on the housing, a conduit that cooling fluid is imported housing, a conduit of from housing, discharging cooling fluid, propose by the present invention, be installed in cooling fluid and discharge a supravasal safety valve, housing in configuration cutter shaft district is equipped with seal, and window that scrap fallaway is used and housing inner casing are distributed in apart from the housing end face in cutting element processing work zone to be had on the different position of certain distance.
The device that proposes in the present invention can improve with cutting element boosts productivity when processing the workpiece of Any shape and any degree of depth, but also can improve the stability of cutting element.Above-mentioned advantage is reached by following measures, be no matter well lead under the effect of the sufficiently high static pressure that forms in housing of metalworking coolant be on the cutting edge of the cutting element in the cutting processing system vertical or level, and owing to workpiece to be machined is installed outside housing, therefore the external dimensions of workpiece and shape just do not have any actual meaning, and what influence the size and the volume thereof of housing is not had yet.
A buoy valve is installed on housing, is suitable and in order to control cooling fluid an electric control one-way valve is installed on the cooling fluid conduit.
So just can make to housing and fill cooling fluid, discharge air, closure casing and finish course of work full automation the power supply cutting element.
