Description
Technical field
The present invention relates to remove the device of interior intersection micro hole burr.
Background technology
Concerning the pipe box class part that is used for the oil circuit conveying, exist some straight holes that differ in size or inclined hole on its circumferencial direction, and size is all more small, diameter is mostly below 1mm.Can produce burr in the aperture exit after drilling, burr is positioned at the cross part of pipe box inner chamber and aperture, and traditional deburring mode is difficult to be suitable for.
Utilize the non-traditional cooked mode of heat energy, luminous energy, electric energy, chemical energy to begin to become the main flow of micro hole deburring, heat energy method, extrusion honing method (abrasive flows method), water jet method, laser method, electric spark method and electrochemical method are several main burr removing methods, have separately some pluses and minuses and applicable situation.The heat energy method be utilize the high temperature that produces in the combustion chamber of sealing so that the burr self-dissolving is gone forward side by side the method that oxidation step comes off, be applicable to blind hole and dark aperture, be not suitable for low-melting alloy, and accessory size is limited, the comparison in equipment costliness.The extrusion honing method adopts a kind of viscosity abrasive material that contains half mobile state of abrasive particle, thereby jelly is removed reaching the orifice edge burr in the die cavity by the part to be processed die cavity back and forth.The minimum deburring of the method aperture is 0.35mm, and surface roughness is higher, and the part that is unsuitable for growing reaches very much removes burr in blind hole.High-pressure water jet deburring mode hydraulic pressure is very high, and impulsive force is very large, to the rigidity requirement of single unit system, accurately positioning requirements is very high, and also also inapplicable to the pipe box class part of end sealing.Laser deburring method speed is fast, precision is high, controllability good, but helpless to the burr that is in concealed location, and the laser equipment cost is very high.The electric spark burr removing method can obtain preferably precision, but burr removal speed is slow, and stricter to the requirement of machining gap, generally needs feed arrangement.
Electrochemical deburring is to utilize electric energy, chemical energy to carry out the purpose that local anodic solution reaches deburring.General electrochemistry cooked mode is, workpiece connects positive source, is called anode, and instrument connects power cathode, be called negative electrode, tool-electrode alignment pieces burr position, and keep certain machining gap between the two, in order to allow the electrolyte of circulation pass through smoothly, general is the solubilized burr within the time of 10～30s, in the time of deburring, produce even, accurate rounding corner in the internal channel intersection, electrolyte rushes electrolysate and the heat that produces in the process from the processing district subsequently.Electrochemistry processing is not subjected to the restriction of material hardness, toughness, and finished surface is smooth, and without thermal deformation, speed is fast, so electrochemical means is fit to carry out microfabrication very much.
Now normal operation fixed negative pole formula electrochemical method deburring is about to shaped electrode and places near the burr, and keeps certain interval, so that burr dissolves as anode, insulating wrapped need to be carried out in non-processing part.For the burr of above-mentioned interior intersection aperture, shaped electrode has two kinds of forms, and a kind of is to insert respectively 1 electrode in each aperture, and this mode machining accuracy is high, and is little on the impact of non-processing part, but aperture when too much clamping efficient low, anchor clamps are too complicated.Another kind of form is to insert a shaped electrode in workpiece cavity, and the part corresponding with burr is the working region, and remainder coats processing.This mode clamping is quick, anchor clamps are simple, yet is only suitable for single product, need make respectively shaped electrode when the similar products model is many, and cost is too high, and adaptability is not strong.So the method for existing electrochemical deburring exists needs shaped electrode, consider the technical problem of machining gap.
