Description

Fluid impact fatigue fracture burr remover and burr removing method
Technical field
The present invention relates to burr removal technology field, and in particular to a kind of fluid impact fatigue fracture burr remover and unhairing Thorn method.
Background technology
Deburring is an important production process, stabs special purpose machine tool, automation via traditional manual unhairing The mode of burr develops.According to rough Statistics, 1972, also only 20 kinds of the method for deburring had been over 80 kinds now. In produce reality, mainly have following several for the method for cross-drilled hole deburring：
1st, heat energy (high temperature) deburring
By the part that band is jagged, after oil removing and drying, to put into be filled with closed container and determine ratio, quantitative hydrogen, oxygen Mixed gas, through spark ignitor, the high temperature to form 3000 DEG C are instantaneously fired using chemical combination process, are heated to part burr molten Simultaneously there is oxidation reaction in erosion state, melt and ablation burr formation oxide with remaining part of oxygen, and burr is to be removed. Because gas is all-pervasive, part burr everywhere obtains disposable cleared.Parts size precision after treatment, rough surface Degree, intensity, metallographic structure, the aspect such as hardness and surface stress is unaffected, and to ensureing part quality, improving work efficiency has significantly Effect.This processing method, process equipment is expensive, and difficult in maintenance, and production cost is also higher.
2nd, abrasive material Flow Technique
Abrasive Flow Machining (Abrasive Flow Machining) is referred to as AFM, at home also referred to as extrusion honing or Abrasive machining.It is a new finishing technology that external last decade grows up.Abrasive flow machining is by with certain viscoelastic Property Special grinding material squeeze through finished surface repeatedly and produce equivalent to grinding cutting act on a kind of processing method.Abrasive flow machining The various surfaces of the machine components of various materials can be ground, polished, be especially suitable for the finishing of compromise face.Abrasive material Stream can be also used for removing the burr of the various processing methods formation on part edge and to part seamed edge rounding, especially suitable In deburring and rounding in small-sized cross bore.The abrasive flow rule of abrasive flows is considerably complicated, and also many problems need solution Certainly, such as：Processing effect and the definite relation of machined parameters, clean problem, the flow behavior of abrasive material in variously-shaped passage etc., In a word, its process can't be completely controlled now.
3rd, electrochemical polish deburring
Part electrochemical polish deburring is substantially that part carries out anode electrolysis processing in electropolishing solution, and this is one Individual unique anodic process.During the anode electrolysis of whole deburring, piece surface carries out two processes simultaneously, i.e. gold Metal surface passivating film is continuously generated and dissolves, and metal surface is in the interaction change of activation passive state.Due to piece surface Roughness is different, at the small burr in surface and microscopic protrusions with more smooth or calixconcavity at chemical membrane enter passive state condition not Together, and because anode region electrochemical dissolution is continuously increased metal salt concentrations, a kind of consistence of high resistivity is formed in piece surface Mucous membrane, mucosal thickness is more relatively thin than at smooth or calixconcavity at smaller burr or microscopic protrusions, and suffered stirring, convection current, diffusion etc. Percussion is then relatively strong, so make have smaller burr or microscopic protrusions position current density larger, electrochemical dissolution speed compared with Hurry up；And then current density is smaller at more smooth or calixconcavity microcosmic position, electrochemical dissolution speed is slower.So smaller burr or microcosmic High spot is more smooth or microcosmic calixconcavity at preferential electrochemical dissolution, so as to reach burr removal and leveling polishing purpose.This side Method processing efficiency is low, and for the burr in blind hole, processing efficiency is just lower, so not being suitable for the cross-drilled hole of master cylinder Burr is removed.
4th, magnetic grinding deburring
Magnetic grinding deburring is a kind of new technology that deburring and Surface Machining are carried out using magnetic field and magnetic abrasive.Its Principle is that the workpiece that will need deburring is put into the magnetic field of two magnetic poles formation, and magnetic mill is put into the gap of workpiece and magnetic pole Material, when workpiece rotates in magnetic field and does axial vibration, under the influence of a magnetic field, there is relative motion, mill in workpiece and abrasive material Material is just ground processing to workpiece surface, reaches the mesh of deburring and polishing.Magnetic grinding deburring application surface is very wide, almost Do not limited by the shape of workpiece.At present, all studying and applying this technology both at home and abroad, having been developed that the automatic magnetic of Special multi-station Power lapping machine.
5th, special tool general laws
Also some companies have specialized in some dedicated tools, and flash removed is removed with the method for machining.Mainly have auspicious Good excellent profit (HEULE) company of scholar, Rosenberg (ROTHENBERGER) company, Nuo Jia (NOGA) company of Israel of Germany Deng.These instruments manually based on, and for the burr on smaller hole also bad processing.
