The air mass flow that the gas transmission control unit is input into cylinder is adjusted, the drill bit 7 is done feed motion with First Speed；
When the resistance that the drill bit 7 is subject to is less than the 3rd default resistance more than the second default resistance, the controller
The air mass flow that the gas transmission control unit is input into cylinder is adjusted, the drill bit 7 is done feed motion with second speed；
When the resistance of the drill bit 7 is more than the 3rd default resistance, it is defeated that the controller adjusts the gas transmission control unit
Enter the air mass flow of cylinder, the drill bit 7 is done backhaul, feeding with third speed and move back and forth；Wherein, the backhaul of the drill bit 7
Distance be 2-5cm.
When the drill bit 7 fathom arrival desired depth when, the controller controls the gas transmission control unit to stop
The air of cylinder 3 is only input into, drill bit is stopped operating, complete the drilling of core.
Wherein, in this embodiment, the First Speed is more than the second speed, and the second speed is more than or equal to
The third speed.The First Speed is initial velocity when drill bit 7 is contacted with the surface of hole workpiece to be drilled 11, and described first is pre-
Handicapping power is initial resistance when drill bit 7 is contacted with the surface of hole workpiece to be drilled 11.When drill bit starts with the surface of hole workpiece to be drilled 11
During contact, drill bit keeps feed speed higher, and core is punched with the feed speed, due to the starting stage in drilling,
The feed speed higher can be smoothly into core certain depth so as to drill to core；When drill bit continues to feed
When, the resistance that drill bit is subject to can increase, in order that must drill being smoothed out, now need to reduce the feed speed of drill bit 7, make drill bit
Fed with second speed, so as to avoid too high feed speed from core 11 is damaged, or even crush core；Then drill bit 7
Continue feeding drilling, the resistance that drill bit 7 is subject to may proceed to increase, in order to avoid drill bit 7 causes to damage to core 11, now can be after
The continuous feed speed for reducing drill bit 7, makes the drill bit 7 do backhaul, feeding with third speed and moves back and forth, until drilling is to predetermined
Depth.In another embodiment, the second speed is equal to the third speed.
In the present invention, the resistance that is subject to of the controller by drill bit in drilling controls the gas transmission control unit
The air mass flow of cylinder 3 is input into, so as to adjust the feed speed of drill bit, drilling accuracy and precision, and drill bit is not only increased

During produce movement, and protective plate can contact with core into face, because drill bit is to the work of core when being prevented from punching
The generation of situations such as core is damaged caused by firmly or crushes, further protects core.
(5), automatic punch of the invention, it is punched in the core print of core so that in casting part production process,
Increase cored density, it is rational when core is contacted with high temperature iron liquid to allow gas to discharge outside core, so that casting part
Shaping is good, it is to avoid have the gas can not effectively to exclude the dialysis of generation gas or puncture high temperature iron liquid or rest on casting
Piece surface or the thicker position of wall thickness that is subcutaneous or being gathered in casting part or casting part highest point or
Person's iron liquid most end end position produce feel suffocated or casting part iron liquid inlet produce gas contracting or in technological design not
The situation that intensive stomata is produced with irrational position is improved to the greatest extent, so as to improve the quality of product.
Described above fully discloses specific embodiment of the invention.It is pointed out that being familiar with the field
Scope of any change that technical staff is done to specific embodiment of the invention all without departing from claims of the present invention.
Correspondingly, the scope of claim of the invention is also not limited only to previous embodiment.
