1 foreword quartz crystal yuan parts of an apparatus basically produces a country to be centered in the Asia, among them China occupies very large dominant position in production value and technical level field. In recent years, accompany our country economy to develop quickly, industry of our country crystal also had greater progress, manufacturer of Japanese main crystal matures his basically product change is produced to our country, make our country becomes the main crystal on the world to produce one of countries. Current, with respect to the amount character, our country has become manufacturing big state, include foreign capital company inside, produce per year a quantity to a few is control only about. Join WTO and the establishment that regard world plant as the position as China, of crystal crop rise, demand of crystal cut equipment is increasing also. The crystal cut equipment previously is import from Japan. Cost of entrance equipment certainly will is high, crystal cut equipment is homebred the requirement that change is bigger and bigger. The quartz that some company produces stage administrative division the research and development of crystal cut equipment is successful, offer more to choose an opportunity for compatriots, can reduce manufacturing cost, improve manufacturing quality. Technology of equipment of 2 crystal cut describes quartz crystal cut process is the process that helps silk sum the compound action with both cut. The movement that pull silk follows drawbench filmy perhaps close put the behavioral just the same that coil. Working process basically can differentiate to put a line, pull silk, control the 3 parts process such as the line. But control precision and stability are taller, need to choose high-end cut silk thread (cupreous silk) . The product of different precision regulation, zhen Pin leads different brilliant, need those who choose different specifications to play silk thread way. Cut process is cut wire is closing in putting an athletic process, place quartz the workbench of crystal with very slow rate (about 5 millimeter are minutely) the goal that speed achieves cut to motion of cut wire direction. The speed of workbench wants slow, movement is smooth, fixed position precision is tall. 3 amount to servo application to design 3.

Of equipment of cut of 1 plan design close putting a share is whole system most rambunctious part; Also be the part that decides equipment manufactures efficiency. To increase manufacturing efficiency and the quality that increase a product. The stage with choice first-rate physical characteristic amounts to servo to close put coil to realize synchro control and constant tension control. The feeling screen in the system is used at interactive operation (setting parameter / position position) ; PLC basically regards servo fixed length as control and constant tension control; Servo is used at fixed length control; Transducer is used at discharging line control. To improve the efficiency of cut equipment, systematic requirement servo can be opened often stop, and make sure high speed is opened stop and in adding decelerate process, should assure to close put a line very smooth. Satisfy a requirement completely via adjusting parameter stage to amount to B series servo. Reach to make sure workbench can run smoothly with the low speed with 5 minutely millimeter increase cut precision, recommend a client to deploy accurate decelerate aircraft. 3.

The composition of 2 control system (1) servo: The stage amounts to B series 0.

4 - 2KW in all the transducer of 5 servo: VFD022B43A two; (2) PLC: ? ù Zuo VP28SV+DVP-01PU; (3) HMI: ? ù Zuo OP-A75BSTD. 3.

3 equipment debug whole system starting, quickly, decelerate, jockey the requirement in the process closes put a line to be able to achieve a balance very quickly. The requirement when starting advocate pull have the taller torsion that start, and rate cannot fall. When the overload ability of 300% assured servo low speed to start tall torsion. To increase work efficiency, demand control system can be fast corresponding rate changes, answer to the change of floating lever also want fast. Servo increases slowdown time need is shorter. Best can close put the servo that coil to add slowdown time to increase slowdown time than pulling silk a bit longer. To assure to start, quickly, decelerate, in stopping a process, close put a system smooth, the position in closing to coil and put the PID parameter of a department and speed gain should be moved a bit bigger; Integral gain setting is nodded greatly a little, integral cycle also should grow a point, can make sure speed is mixed accordingly quickly so the balance of float bar. Additional, when use PLC program grows quite, sweep time is longer, to constant tension close put a response rate the impact is very big. Little use FROM/TO dictates and had better simplify as far as possible PLC program. Function of crystal cut equipment can satisfy the quartz that the labour that 4 last words amount to with the stage accuses a system to finish completely the client's requirement, crystal cut precision and efficiency get rising, achieved the result that expects a design. The system is started, quickly, process of trends of decelerate, inactive, floating lever stability is in balance position swings slightly inside a very little scope. CNC Milling CNC Machining
