Summary: The article uses controller of motion of ohmic dragon CJ1W-NCF71, use bus line of synchronism of its high speed to control a technology, and the position / function of switch of torsion high speed, combine drive of series of ohmic dragon bus line W/N-ML2, introduced accident of Die Casting of high speed semiconductor to use control system. Keyword: Switch of high speed of position of torsion of bus line of athletic controller servo technology of figuration of 1 foreword semisolid (call SSM preform way again) , this kind of method has said metallic juice agitate above all, the metal of half solid state that obtains having character of half solid state (SSM) , again prefab the preform of the measure that becomes need and appearance, the course heats, put Die Casting machine pressure room, touch into figuration of travel Die Casting next change inject figuration casts pressure tall, can promote the heat between metallic mould and oar of magnesium alloy makings to deliver, bring about the grain near the surface to be changed imperceptibly, gifted to figuration product Gao Naishi sex and mechanical intensity.

Current, use touch change inject figuration technology is OK camera of computer of preparation mobile phone, notebook, number, photograph the housing that waits for portable communication equipment like measuring projector of camera, liquid crystal.

At present this is planted equipment of Die Casting aircraft, basically import from Japan, its core control uses special controller partly, cost is very high, to enhance product competition ability, domestic some company uses controller of motion of ohmic dragon CJ1W-NCF71 now, use bus line of synchronism of its high speed to control a technology, and the position / function of switch of torsion high speed, combine drive of series of ohmic dragon bus line W/N-ML2, very good application receives in machine of Die Casting of high speed semiconductor, cast off the history that counts Europe and Japanese entrance equipment before successfully at the same time, initiated the new page of machine of Die Casting of semisolid of domestic own research and development. 2 systems show   2.

1 craft explains high pressure and high speed are the 2 big features of die-casting craft, cast is filled model in good condition, clear-cut basically depend on Die Casting speed (namely Die Casting process) , and the in-house quality of cast and mechanical function basically depend on pressure boost effect (namely pressure boost process) , the Die Casting that wants to acquire high quality, must be opposite according to different situation all craft parameter in Die Casting process if pressure and Die Casting speed have proper control, because this is before Die Casting process paragraph, use speed control, duan Cai uses torsion control after, undertake pressure boost and protect pressure, in speed and torsion switch moment, the hope on craft asks to achieve " 0 switch time " , do not have dead band time namely, pressure boost process is medium at the same time, torsion output degree of linearity is tall, torsion control precision is achieved 0.

01Nm.

, if the graph shows 1 times,technological arrangement pursues: Graph   of graph of 1 technological arrangement 2.

The athletic controller of tradition of 2 control difficulty has positional control and speed control only, but control of speed of the need in the system and torsion control online switch, speed and torsion switch time, the client hopes to achieve 0 switch, but practical effect be patient of is the biggest 32ms error, torsion output degree of linearity is tall, output precision is achieved 0.

01Nm. The solution uses 3 ohmic dragon the position of CJ1W-NCF71 / speed / torsion switch function, the CJ1W-NCF71 of the ohmic a surname of functional;   that can pass simple echelon plan statement to be able to fulfil a need uses bus line of high speed synchronism to control a technology, the biggest control 16 axes, synchronous scanning cycle is 1-8ms only (axial amount is different and the basis is different) , department altogether 4 servo, synchronous scanning cycle needs CJ1W-NCF71 of 3ms;   ohmic dragon to use communication instruction to change means to control driver to move only, instruction resolution is very high, the biggest resolution is achieved 0.

01% , because this torsion outputs precision,can achieve 0.

0001Nm. 4 configuration and flow specification   4.

1 configuration specification controls a share: Part of CJ1W-NCF71+CJ1W-CT021;   servo: * of * of * of 4 * R88D-WN - ML2. Control program can use the CJ1W-NCF71 controller that is based on CJ1 series, will realize the synchro control that amounts to 16 solid axles through bus line of communication of ML2 high speed, inside buy speed and torsion pilot are online switch function, the user needs to be called simply only inside buy function is fast, input place to need parameter to be able to finish driver of complex; of much axle control to use R88D-WN × × - the servo driver of mouth of communication of ML2 of the buy inside ML2 series, feeling screen uses the feeling screen of NS-10 series, charge an editor of the picture that finish and control through the buy inside SAP. If the graph is shown 2 times,the system configures a graph. Graph if specification of control of specification of technological process of control of Nextpage5 of plan of 2 systems configuration pursues show 3 times. A) B of block diagram of systematic control technological process) graph of systematic control process pursues 6 programs show flow chart of 3 systems control program structure is very simple, use FB of the buy inside ohmic dragon (program function is fast) can very fast finish relevant process designing, in the input output writes good place to need to get parameter for example torsion, speed of clamp down on, axial node date can, graph the 4 FB that listed torsion controls a process. Graph course of 7 last words tests program of 4 torsion control for long, the system can be stabilized move, and batch turns production, at present this equipment has been paid close attention to after research and development is successful by industry stress, of machine of semisolid Die Casting homebred change, cast off the history that counts the United States and Japanese entrance equipment before successfully, initiated the new page of machine of Die Casting of semisolid of high-tech of domestic own research and development.
