Description
Technical field
The invention belongs to the Milling Process technical field, relate to a kind of servicing unit of Milling Process, especially relate to a kind of energising heating servicing unit for Milling Process.
Background technology
Along with developing rapidly of modern industrial technology, at the induced one new material (such as high strength, unimach, stainless steel, titanium alloy, chilled cast iron and high-temperature alloy material etc.) of a lot of high strength, high rigidity of the industrial departments such as machine-building, electromechanics, weapons and aviation, 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 large, 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 such as superhard cutter material (diamond cutter and cubic boron nitride cutting tool), sintex and coated cutting tool etc.
2, research promotion new processing method, such as vibrocutting, the methods such as hot machining, laser or beam heating processing.
Hot machining is to carry out to difficult-to-machine material one of effective ways of high efficiency processing, it is in working angles, by 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 to some extent and is easy to produce plastic deformation.Compare with conventional 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.The methods such as domestic and international useful laser, plasma, induction, energising heat.
The energising of the continuous cuttings such as existing turning adds device for heat treating referring to Fig. 2, it is the loop that utilizes cutter and workpiece to consist of at common car (brill) bed that present conductive heater car (brill) is cut, pass to low-voltage, high-current, make the cutting region material resistance produce the Jiao Er thermal softening, make cutting become smooth.This mode is suppressing unique advantage aspect squama perverse and built-up edge and the hard turning, its shortcoming is that whole working angles requirement is continuous cutting, otherwise will produce electric spark, be only limited at present the continuous cuttings such as turning, drilling, and be that cutter and workpiece heat simultaneously.The energising heating servicing unit that is applicable at present Milling Process there is not yet report.
Summary of the invention
The purpose of this invention is to provide a kind of workpiece heating of only having, cutter does not heat, and can make the fast rising and softening of workpiece processing stand place local temperature, and the realization universal cutter heats servicing unit to the energising that is used for Milling Process that the high rigidity workpiece is done Milling Process.
The present invention is provided with current and power supply, auxiliary electrode positive pole, auxiliary electrode negative pole, vibrating sensor, infrared sensor, felt pad, insulation sleeve and computer; The auxiliary electrode positive pole connects the current and power supply positive pole, and the auxiliary electrode negative pole connects the current and power supply negative pole, and auxiliary electrode positive pole and auxiliary electrode negative pole all touch with outside workpiece to be processed; Vibrating sensor is located on the outside workpiece to be processed; Infrared sensor is located at by the outside workpiece to be processed; Felt pad is located between outside workpiece to be processed and the milling machine table; Insulation sleeve is located between the outside milling cutter and machine tool chief axis; The signal output part of vibrating sensor and the signal output part of infrared sensor all connect the signal input part of computer.
It is that 0 ~ 10V and electric current are the low-voltage and high-current power supply of 0～500A that described current and power supply preferably adopts voltage.
Described felt pad can adopt mica sheet.
Described insulation sleeve can be the plastic cement insulation sleeve.
Described auxiliary electrode positive pole and auxiliary electrode negative pole all touch with outside workpiece to be processed, and preferably auxiliary electrode is anodal contacts with workpiece to be processed point, and the auxiliary electrode negative pole contacts with the workpiece to be processed face.
Operation principle of the present invention is as follows:
Current and power supply starts, and the auxiliary electrode conduction can make rapidly workpiece processing stand place local heat softening during large electric current, and milling cutter is insulated owing to insulation sleeve, and the milling cutter no power does not heat.When workpiece temperature reaches target temperature, carry out again milling after softening.
Only need use universal cutter to carry out Milling Process to the workpiece of high rigidity during milling of the present invention, can greatly reduce tool wear, and process need not cooling fluid, has reduced the environmental pollution that cooling fluid is brought in the process and post-processed problem, and this is a kind of Green Machining.Simultaneously, the present invention uses universal cutter, and processing cost is reduced greatly, realizes that the high rigidity workpiece uses the dried Milling Process of universal cutter.
