Abstract
A digital wire drawing die ultrasonic shaping polisher is mainly composed of a tool metal needle, a piezoelectric ceramic transducer, an ultrasonic power amplifier, a digital procedure controller, a detection circuit and corresponding circuits. A machine digital closed-loop control method can allow the piezoelectric ceramic transducer to always output at a constant amplitude during the ultrasonic vibration processing process of a wire drawing die, which can obtain the maximum processing efficiency; at the same time, the processing quality is improved and the energy consumption for heating is reduced, thus ensuring the consistency of the technological conditions during the processing process of the wire drawing die and improving the stability of the production technology of the wire drawing die and the consistency of product quality.
Description
(1) technical field:
The utility model belongs to ultrasonic wave shaping, polishing field, specifically a kind of digital wire drawing die ultrasonic wave shaping polishing machine.
(2) background technology:
Wire drawing die is the instrument that draws various metal wire rod most criticals.Wire drawing die as the various metal wire rods of instrument drawing must have very high hardness, for example: with superhard material manufacturings such as diamond, polycrystalline diamonds.Simultaneously, taper compression work district, the cylindrical shape sizing area of wire drawing die endoporus must have certain pass precision and very high fineness.For the endoporus at superhard material processes taper, the cylindrical shape that size is accurate, fineness is very high, need to adopt ultrasonic wave carry out shaping and polishing to wire drawing die.Existing ultrasonic wave shaping polishing machine drives piezoelectric ceramic transducer generation ultrasonic wave with ultrasonic-frequency power supply the endoporus of wire drawing die is processed, and belongs to open-loop control system.Before processing, need the operator to start vibration of ultrasonic wave by the electric frequency of regulating ultrasonic-frequency power supply with sensation and experience.In process, need the operator to make ultrasonic vibration system be operated in resonant condition by the electric frequency of regulating ultrasonic-frequency power supply with sensation and experience, so that obtain big amplitude, guarantee carrying out smoothly of processing.Because in the Ultrasonic machining process, the influence of series of factors such as the variation of load, system's heating, working (finishing) area variation, the wearing and tearing of instrument metal needle, make the resonant frequency of vibrational system to drift about, this just needs the operator that the electric frequency of ultrasonic-frequency power supply is often regulated, otherwise system will be operated in the disresonance state, the output amplitude of ultrasonic vibration system is reduced, the process instability, working (machining) efficiency descends, and also is difficult to process time expect.
By investigation, do not find not enjoy, produce, use digital wire drawing die ultrasonic wave shaping polishing machine to present wire drawing die manufacturer.By to the consulting of relevant technologies publication, books, there are not to find report, record about digital wire drawing die ultrasonic wave shaping polishing machine.By existing Chinese patent retrieval is consulted, there be not the patent of discovery about digital wire drawing die ultrasonic wave shaping polishing machine.
(3) summary of the invention:
The purpose of this utility model provides a kind of digital wire drawing and touches ultrasonic wave shaping polishing machine, this digital wire drawing die ultrasonic wave shaping polishing machine method of closed-loop control, can make the vibration of ultrasonic wave system be in the resonance duty all the time, piezoelectric ceramic transducer can be all the time with constant, big amplitude output, and this has just improved process velocity, has also made working condition more stable simultaneously.
The technical scheme that the digital wire drawing die ultrasonic wave shaping polishing machine of the utility model indication adopts is as follows:
1, the input of piezoelectric ceramic transducer 3 input of connection detection circuit 6 simultaneously so that constantly the duty of piezoelectric ceramic transducer 3 is detected, and is transferred to digital process controller 5 constantly with monitoring result.
2, digital process controller 5 is by s operation control ultrasonic-frequency power supply amplifirer 4.
3, ultrasonic-frequency power supply amplifirer 4 is exported to the electric energy that modulates the input of piezoelectric ceramic transducer 3.
4, piezoelectric ceramic transducer 3 drives instrument metal needle 2 and produces resonance, adds diadust at the syringe needle place of instrument metal needle 2 wire drawing die 1 is processed.
Contrast existing technology, the beneficial effect of the digital wire drawing die ultrasonic wave shaping polishing machine of the utility model indication is: because testing circuit 6 and digital process controller 5 have been arranged, this system is a closed-loop control system, can replace manually ultrasonic vibrations process being monitored constantly and being regulated, make system be in resonant condition work all the time, can obtain peak swing, significantly improve working (machining) efficiency.
(4) description of drawings:
Accompanying drawing is the schematic perspective view of digital wire drawing die ultrasonic wave shaping polishing machine.
(5) specific embodiment:
Optimal way of the present utility model is as shown in drawings:
Comprise in the accompanying drawing: wire drawing touches 1, instrument metal needle 2, piezoelectric ceramic transducer 3, ultrasonic-frequency power supply amplifirer 4, digital process controller 5, testing circuit 6,
1, testing circuit 6 before system starts and in the process detects each variable quantity of piezoelectric ceramic transducer 3, and then is transferred to digital process controller 5.
2, according to experiment, find out each variable quantities such as comprising pressure, temperature, ultrasonic resonance size, it is quantized, draw out the curve of each factor and output ultrasonic wave vibrations relation, analyze its influence to the transducer output amplitude, the hardware circuit of design digital process controller 5 is determined control algolithm, program, form digital process controller 5.
3, the assembling device that selector switch speed is fast, power attenuation is little, big, the withstand voltage height of conducting electric current, strong shock resistance, driving power are little is formed ultrasonic-frequency power supply merit device 4.
4, redesign, making piezoelectric ceramic transducer 3 are so that reach the optimum Match of whole system.
