摘要: 电火花线切割加工(wire-EDM)是一种基于电火花加工技术的适应性流程加工技术,它可以被用在具有二维到三维复杂形状的而且是导电的原材料的加工上。电火花线切割加工最常见的应用是在压模、挤压模、粉末冶金的铸模和标准摸板的装配工中。这样就可以加工出以往依靠花费很高磨床或昂贵的传统意义上的电火花的电极来进行加工的工件。由于电火花线切割加工技术是机电一体化技术,是机械、电工、电子、数控、自动控制、计算机应用等多门学科、专业知识的综合运用。
我的设计课题是DK7732数控高速走丝电火花线切割机及控制系统设计。DK为数控电加工机床,77为电火花线切割机床,32为机床工作台宽度。
此次设计包括机床的总体布局设计,横向进给、纵向进给设计,其中还包括齿轮的强度计算,滚珠丝杆较核,轴承寿命的验算。控制系统部分包括步进电机控制电路和脉冲电源电路,这是数控电火花加工机床的重点设计部分,也是难点。步进电机电路设计包括硬件电路设计和软件系统设计。详细说明了芯片的扩展、键盘显示器接口的设计等等。脉冲电源电路采用高低压复式脉冲电源,它是由晶体管及分立元件组成的电路,输出高低压复式脉冲,可以同时供给两个放电间隙加工,提高生产效率。
关键字:数控高速电火花线切割加工、主轴运动、步进电机、脉冲电源。
Abstract: Wire electrical-discharge machining(wire-EDM) is an adaptation of the basic EDM process, which can be use for cutting complex two-and-three-dimensional shapes through electrically conducting materials. Wire-EDM is most commonly used for the fabrication of press stamping dies, extrusion dies, powder composition dies, profile gages, and templates. Complicated cutouts can be made in difficult-to-machine metals without the need for high-cost grinding or expensive shaped EDM electrodes, Because the technology of wire electrical-discharge machining is the technology of mechatronics, and it is the integrate application of many subjects and professional knowledge, for example mechanism, electrician, electron, numerical control, auto control and computer application.
My design subject is DK7732 numerical control electrical-discharge perforation molding machining tool. DK means numerical control machining tool. 77 means wire electrical-discharge perforation molding machining tool. 32 means the width of tool’s worktable.
The design contains collectivity distribution design, landscape orientation feed design, portrait feed design, circumgyrate worktable design. It still includes intension calculation of gear wheel, the checking of ball bearing pole and the calculation of axis gearing life-span. The controlling system part contains the circuit of step-by-step electromotor control and the circuit of pulse electrical source. This part is the most important part of numerical control electrical-discharge machining tool, and it is very hard for me. The design of step-by-step electromotor control includes hardware circuit design and software system design. It explains the enlarging of CMOS chip and the design of keyboard display interface. The circuit is composed by transistor and unattached elements, it exports high and low voltage pulse, which can apply with two electrical-discharge interval and improve productivity.
Key words: Numerical control wire electrical-discharge machining, principle axis motion, step-by-step electromotor, pulse electrical source
