【Abstract】 With the development of industry, various products made of metal bar are extensively used in most fields of modern Engineering. In most cases, metal bars with different shapes are used simultaneously. This research aims at the designing on new reinforcing bar cutter, presenting a mechanical design method for this new cutter, giving a computer controlling method of new cutter and showing a prototype to accelerate its common, use.This paper is based on previous theory and practical design After the review of machining methods various metal bar straightening machines and twisting machines, this new cutter is now being studied. This paper can be divided into four parts. Firstly, it expatiates on the power part in detail, including the structure N working theory> fundamental theory of vector control of the servomotor system. Secondly, it does some research on mechanical structure and presents the drawing of delivering > straightening and cut-off sections, embracing design methods > functions and practical drawings. Thirdly, vector controlling theory of servo driver in servomotor system has been applied during design process; closed loop timing driving N hardware structure-, controlling scheme of software and controlling circuit are introduced. Design scheme of closed loop controlling system for this new cutter is also presented. Finally, control system based on industrial computer is designed according to necessary function of new cutter. This work is concerned with servo modeling design, which consists of the whole structure of servo model, software design of servo controller. What’s more, some research on industrial computer has been done.This research generally presents mechanical design of new cutter and introduces some original ideas about design scheme. All this work can give some advice on mechanical design of new cutter. This paper is completed based on mechanical design and drawing during the school year, production can take structure drawings and part drawings as reference. The structure drawings and part drawings of this paper can be practically utilized in the process of production.This paper can give some advice on software design. It analyzes controlling theory and servomotor system and does some research on how to control servomotor systems by industrial computer, the work is the foundation for optimizing controlling scheme.This paper solves some problems possibly occurred in actual processing, which gives some advice on a batch production and maintenance of new cutter.更多还原
