Description
Technical field
The utility model relates to Technology for Turning Machining, especially relates to a kind of energising heating servicing unit that is used for turning processing.
Background technology
Along with developing rapidly of modern industrial technology, introduced the new material (as high strength, unimach, stainless steel, titanium alloy, chilled cast iron etc.) of a lot of high strength, high rigidity at industrial departments such as machine-building, electromechanics, weapons and aviations, these materials are referred to as difficult-to-machine material.Because their high strength, high rigidity and high-strain hardening rate significantly worsen its machinability: add big, the temperature rise of cutting force in man-hour, tool wear is serious, and machined surface quality is poor, and the metal resection rate is low.To the processing of these difficult-to-machine materials, people recognize gradually, depend merely on general change cutting data, and the method for preferred tool geometry angle has been difficult to prove effective.Solve the processability problems of this class material, two kinds of methods generally arranged at present:
1, the more excellent cutter material of development performance is as superhard cutter material (diamond cutter and cubic boron nitride cutting tool), sintex and coated cutting tool etc.
2, the new processing method of research promotion, as vibrocutting, hot machining, laser or ion speed add methods such as hot-working.
Hot machining, be the earliest 1890 German helper slave door (B.C.Tilghman) material has been carried out energising hot machining, after the 2nd world war, because many difficult-to-machine materials that are used for navigation, aviation and other military fields are met difficulty when common cutting, hot machining just really begins to come into one's own.Hot machining be can to difficult-to-machine material carry out high efficiency processing one of effective ways it be in working angles, pass through variety of way, heat being cut material, make cutting microcell, top layer or the whole method of cutting again after the suitable temperature that reaches.Its objective is that the hardness, the intensity that make machined material descend and is easy to produce plastic deformation.Compare with common cutting, descend owing to being cut higher its shearing strength that makes of layer temperature, therefore reduced cutting force and power consumption, production efficiency improves, and cutter life prolongs.In addition, because the cutting region temperature is higher, built-up edge and squama thorn are difficult to form, and machined surface roughness is obviously reduced.Methods such as domestic and international useful laser, plasma, induction, energising heat.
The LASER HEATING assisted machining is to utilize high power density laser beam heats cutting region material, makes its softening purpose that reaches the plasticity cutting.Adopt the LASER HEATING assisted machining can improve cutting speed, cutter life, reduce cutting force and cutting temperature, obtain good machined surface quality.But laser instrument involves great expense, and floor space is big, and needs special fixture to limit the use of laser heating method in the heating assisted machining process.
Plasma heats the plasma gun that its principle mainly is to use a special use, in the air-flow that plasma is changed, produces electric arc, makes the part of workpiece produce high heat in cutting region.Make on the whole cutting depth in cutter front and can both heat by adjusting and control plasma gun.In fact, the thermal treatment zone only remains in the depth of cut of removal, makes the temperature of finished surface of part can remain on the structure of metal and below the indeclinable temperature of crystal grain.Heated metal is downcut by cutter under chip deformation.It is high especially that the subject matter of plasma heating means is that the relative position of plasma-arc and workpiece requires, process workpiece and cutter relative velocity are bigger simultaneously, be difficult to guarantee the position of heating, and need the length of control electric arc just can reach desirable heated condition in the process.
Early 1960s, people such as the last former nation of Japan scholar hero have proposed energising hot machining method, promptly when cutting, utilize cutter and workpiece to constitute the loop, apply low-voltage and high-current, make the cutting microcell obtain heating, thereby efficiency of heating surface height, heat up rapidly, the while compact conformation, temperature control is simple, be suitable for various cutting working methods, be the hot machining mode that a kind of utmost point has development potentiality, studies show that in recent years selects for use carbide alloy coating cutter can solve the low excessively problem of critical speed in the energising hot machining.This method has been advanced people's practical stage in countries such as Japan, Russia and Britain now, and it uses the processing aspect expansion of the more difficult-to-machine materials of forward.
Since 1988, the Ye Bangyan of South China Science ﹠ Engineering University, Zhao Xuezhi etc. are by a large amount of experiments and research, to the power-supply device of electric hot machining make, aspect contents such as cutting force, cutting temperature and the machined surface quality of electric hot machining and tool life have done the deep research of system.
Existing electric hot machining is the power circuit that utilizes cutter and workpiece to constitute on engine lathe, passes to low-voltage, high-current, and at point of a knife and workpiece contact point place, the Jiao Erre by contact resistance produces makes the cutting region material softening, thereby allows cutting become smooth.This mode is beneficial to aspect squama perverse and built-up edge and the hard turning suppressing, but heat simultaneously because of cutter, workpiece, it is very short to be cut a time of zone heating on the workpiece, in the process that workpiece may also soften fully, cutter is also cutting, and has also just increased tool wear, have only cutter to follow workpiece contact place that contact resistance is arranged in addition, be the single-point heating, the temperature that the workpiece heating obtains under the same current is lower, and the efficiency of heating surface is lower.
