Limited company of technology of numerical control of Andy of Dalian of company brief introduction is the company of new and high technology that joint investment establishs the person that put in doctor and domestic automation 's charge to learn by sea taking day. The company is located in area of Dalian city new and high garden abroad student poineering garden. Be be engaged in technically be being mixed at servo of synchronism of communication permanent magnetism the research and development that communicates asynchronous servo, make, the automation that sale and service are an organic whole controls a company. The company can offer perfect solution for the client. Series of ADSD-AS of product characteristic 　 communicates asynchronous servo driver to be based on the hardware platform of DSP+IPM, function is reliable, answer speed tall, function is perfect, have a variety of control means, agile outside terminal run mode, convenient moving signal to wait from the definition, protective function is perfect, offer way of standard RS485 communication, but comfortable match the import such as SIEMENS, FAGOR numerical control system and homebred Guangzhou numerical control, China in numerical control, stage amounts to numerical control of numerical control, Dalian to wait, sexual price is higher, can apply extensively at the machine tool, pack presswork, spin printing and dyeing, rubber-plastic the industry such as machinery, but hoist class, improve product quality, improve efficiency, improve technology, reduce unit production value cost. Use on plastic screw extruder especially, afore-mentioned characteristics are more apparent. The transforms purpose 　 ● to raise plastic screw extruder property that uses at screw extruder and class, immanent quality that improves a treatment product and exterior quality. ● simplifies the rigid structure of plastic screw extruder, decrease cast, machine treatment process, shorten the installation of whole equipment debugs periodic, managing rolled steel, reduce equipment to maintain cost. ● reduces the integral installed capacity of plastic screw extruder in electric field, reduce power consumption, managing charge of electricity. ● improves craft to improve manufacturing efficiency, managing production cost. Before plastic screw extruder is transformed, hind systematic composition and the electromagnetism timing electric machinery that analyse the screw machine before transforming to use a convention add electromagnetism governor or communication asynchronous electric machinery adds coder, the low speed for contented screw machine (highest 150 turn the left and right sides) torsion requirement, must increase electric machinery capacity to deploy reducer casing. After transforming, because communicate the function of torsion of admirable and characteristic low frequency of servo to rise greatly, reduced the electric machinery capacity, reducer casing in cancelling original orgnaization (or the speed ratio that reduced reducer casing) , the construction of system of screw machine gets simplifying, function gets mentioning, make equipment produces manufacturer and equipment to use the economic benefits with be obtained regular thereby. Transform case and analytic case one Nextpage analyses this plan is to transform a production to compare early vintage screw extruder, the 1000 rated rotate speed that turn more, long-term however job is in 100 turn more, groove of short of of electric machinery function, increased specific power consumption to satisfy operating mode to ask to must increase electric machinery type selecting. Additional, efficiency is inferior also, create very big waste, the product quality of treatment is not high also. And after transforming, because used electric machinery of low frequency big torsion and servo controller, make electric machinery works at optimal state, not only reduced specific power consumption, also improved the efficiency of screw machine, improved machines product quality. Case 2 analysises this plan is the screw extruder that transforms a frequency control means that using normally at present, although used transducer,improved timing performance. But, systematic electric machinery is in the state that low frequency works for a long time, did not get fundamental improvement. And after transforming, at case one identical, because used electric machinery of low frequency big torsion and servo controller, make electric machinery works at optimal state, not only reduced specific power consumption, also improved the efficiency of screw machine, improved machines product quality. The screw rotate speed that because plastic screw extruder is designed,narrates on conclusion put together is inferior, top rotate speed is in more 150 the left and right sides. Choose active electric machinery to procrastinate change way, ask taller decelerate is compared, the timing scope of controller and control precision are inferior also, and the plan that adopts Andy numerical control to offer, dropped the rated point of electric machinery, rated turn up arrives under 200rpm. And of the output torsion as a result of low frequency electric machinery promote considerably, can reduce speed ratio of systematic gear case or cancel gear case, withhold decelerate of one class leather belt or chain decelerate only, simplified facility construction, managing cost, prevented as a result of mechanical link locked-rotor attaint electric machinery effectively also. Additional, electromagnetism timing and frequency control are put in certain blemish. Slippery poor timing, frequency control of small; of scope of low, timing is in precision the torsion when electric machinery low speed and efficiency are reduced apparently. Consequently, to satisfy operating mode to must increase electric machinery size. And Andy servo driver can make sure constant torsion is outputted under electric machinery fundamental frequency, have the overload capacity of 3 times rated torsion, but stable, accurate control electric machinery. Control means comparing with the tradition, have older technique advantage, reduced effectively with n, improve the control precision, efficiency that improved facility, product quality that improved an user. Improved the performance of plastic screw extruder, increased a business the competition ability in the person of the same trade, bring regular economic benefits finally. CNC Milling CNC Machining
