Summary: Use transducer technology to undertake transforming to planer of B1012A thin arm, reduce specific power consumption in order to improve the quality that its machine, efficiency. Keyword: Thin arm planer; Transducer; Planer of parameter preface B1012 thin arm already used more than 30 years, workbench transmission system uses dc dynamo one electric unit, tall, the sources of energy uses up fault rate very big. System of transducer pilot electromotor is having energy-saving effect remarkable, adjust control is convenient, safeguard wait for an advantage simply, use general transducer to undertake transforming to this machine tool so. The main part of planer of fundamental condition thin arm includes planing machine of the 1 B1012A before transforming thin arm safety of box of gearing of lathe bed, workbench, pillar, beam, workbench, feed, lubricant system, hydraulic pressure and electric equipment. Workbench transmission system uses dc generation set one electric unit and the 2 assorted speed change that block gear, the decelerate of achievable workbench, retrorse, slow fast cut wait for a movement, belong to advocate procrastinate use a system. Crossbeam clamp and litre fall to move and rotate what reach tool carrier belong to auxiliary procrastinate use a system. Workbench motion is controlled automatically circularly used combined-type to be close to switch. The control requirement A of planer of 2 thin arms. Stepless speed regulation and timing range is wide, it is good that the system moves flowing sex; B. Can adjust according to different workpiece freedom working rate, and advancement and regressive speed can be adjusted alone; C. It is as good as function of apply the brake to start; D. System simple, on the safe side, facilitating maintenance, noise low, efficiency is tall and energy-saving and apparent. 3 workbench advocate procrastinate move a system to transform 3. 1 electric machinery and transducer and outside of fittings choose workbench advocate procrastinate move a system to use a Y225M one 6 model, 37kW asynchronous electromotor, the one 4CX of FRN45G11S that transducer uses Japanese Fuji company to produce transducer. (considering characteristic of job of bed of thin arm planer, the transducer that chooses so is bigger than the norms of electromotor one class. ) drive because of transducer advocate electric machinery can produce very big feedback energy when fast inverting apply the brake, use retarding brake and unit of resistor of exterior apply the brake to the inverting apply the brake of planing tool when transform so (the investment of resistor of apply the brake of transducer moves, the means that can make this part energy gives out heat through resistor is used up) . In order to raise transducer the ability of apply the brake when decelerate, make effect of apply the brake better. 3. 2 transducer are exterior hookup (see figure below) 3. The adjustment of parameter of 3 transducer function the requirement that to make transducer satisfies bear and run mode, need main to transducer parameter to make following set. 3. 3. F01 of 1 frequency set is frequency set function, key of 0 clavier face plate can choose to adjust machine tool parameter when debugging. 1 voltage inputs optional choose when the job (terminal [12]0, 10V set) . Specific can ask according to traversal speed set. 3. 3. F02 of 2 moving operations handles an order to move, choice set is 1, by outside terminal [FWD] , [REV] input runs a command. 3. 3. 3 add slowdown time F07 to quicken time, F08 slowdown time all set is 1. 8s (provide stereo to use the effect actually to decide) . 3. 3. 4 torsion promote F09 torsion promotion, normally considering electric machinery the job falls in low speed condition, so F09 should be set for 10 the left and right sides, namely constant torsion is characteristic. But should notice, when torsion promotion increases, low speed domain can have produced excitation condition. When moving continuously by this kind of condition, electromotor may produce overheat, should check drive electromotor character. 3. 3. 5 frequency limitation considers use general electric machinery, answer because of frequency of this F15 upper limit set is 50Hz. 3. 3. Electromotor of P01 of set of 6 electromotor parameter extremely number is set for 6 extremely, p02 electromotor capacity is set for 37kW, set of rated electric current is P03 electromotor 71A, p04 set electromotor is rectified oneself choose P04=2 surely (the requirement breaks away from load to rectify calm) . 4 last words use transducer to be opposite workbench of planer of B1012A thin arm advocate procrastinate move systematic dc dynamo after one electric unit is transformed, the course moves, satisfy the requirement that manufactures technology completely, reduced specific power consumption, improved manufacturing efficiency, adjust control is convenient, safeguard a quantity to be reduced apparently.
