Description
Technical field
The present invention is a kind of high efficiency metal pipe composite electrolysis wire cutting device.A kind of complex machining device that relates to Electrolyzed Processing, the cutting of sand line, electrolytic wire cutting, electrolysis and mechanical grinding particularly.
Background technology
Generally adopt the method for wafer saw cutting to cut during at present to metal pipe material or other blank blankings.Have during cutting that cutting force is large, otch is coarse, burr is many, and noise is large, smear metal and spark splash, and working environment is very abominable, and workers ' health can not get good guarantee.
Electrolyzed Processing is to utilize metal in electrolyte, the principle of anodic solution can occur, a kind of special processing technology that part is shaped.During Electrolyzed Processing, the positive pole of power supply connects anode workpiece, and negative pole connects cathode tool.Keep less gap between two electrodes, electrolyte flows through from the pole clearance, makes to form conductive path between the two poles of the earth, utilizes the voltage of processing power source to produce electrochemical reaction at the finished surface of workpiece.Along with the continuous feed of the relative workpiece anode of tool cathode, workpiece material is constantly dissolved ablation, and product is taken away machining area by the electrolyte that flows in the gap thereupon.Surface of the work forms the shape substantially similar to the tool work face gradually.
The cutting of sand line is exactly to utilize the sand line to move back and forth, and makes sand line and workpiece produce the purpose that grinding reaches processing.The sand line is generally to use carborundum line, is that a kind of high tensile steel wire or copper wire skin are coated with diamond grit.Can be used for cutting various metals and nonmetallic composite, glass, rock material, jewel, monocrystalline silicon, carborundum, polysilicon, refractory brick, pottery, epoxy plate, ferrite.To conduction and electrically non-conductive material, as long as little can the processing of hardness ratio sand line.
