The accurate processing of metal work piece plane mostly adopts abrasive machining technology in present, this technology has been mature processing method, and is widely used in mechanical industry. But in the abrasive machining technology, the consumption of emery wheel is unavoidable; in order to avoid the abrasive burning, the continuous supply of coolant is necessary. In the process of grinding nonferrous metal, the paste and block of emery wheel makes it difficult to continue, which is the difficulty that has not been solved until now.
The plastic precise-processing technology to metal plane is the comprehensive application of the metal plastic process technology and precision process technology in the metal plane. According to the plastic deforming principle of metal under certain conditions, metal would produce continuous and partial plastic deformation under rolling pressure, so that change and improve the final surface quality and property.
This paper is an important component of overall research about continuous partial plastic-precise deformation and precision process which is researched by my tutor-professor Song YuQuan. The article is about the design plan of metal plane plastic precise-processing machine based on mechanical shaping machine specified in professor Song YuQuan’s practical new-type patent “the plastic precise-forming device” ,i.e. taking the ram-motion of mechanical shaping machine as X direction dynamic mechanism, the feeding motion of working platform as Y direction movement of the plastic precise-processing machine to metal plane, the feeding-movement device and its control system in Z direction are designed and produced by ourselves, so that the basic plan and design idea of the plastic precise-processing machine to metal plane are specified. Although there are some creative ideas in the patent, there still need quantity of improving, supplement and perfecting works to make the model machine low cost, automatic control, working steadily and excellent quality.
The following works have been done in the premise of data-collection and commenting on the research area in the article: by contrasting the arts between rolling processing technology and shaping processing technology, and comparing the features between mechanical shaping machine and hydraulic shaping machine, the overall mechanical plan of the plastic precise-processing machine is specified, the mechanical shaping machine is replaced by hydraulic shaping machine and added ensuring and fitting the rolling processing craft axis feeding device and its control system、the data-measurement and collection device、mechanical workpieces machined、the installation and test of the mechanical device、the circuit arrangement of control system、the installation and test of control device and the sensor’s demarcate, so that the plastic precise- processing machine to metal plane is researched. The plastic precise- processing machine to metal plane comprehensively uses mechanical technology、hydraulic technology、electric technology and computer technology, the primate movement in X direction has widely adjusting velocity range and can realize the automatic raise the knife rest device in quickly coming back, the applying of light-grind line movement sensor and the computer can measure and save the date of velocity in the prime movement precisely, so that the experiment method of seeking the relationship between rolling velocity and the processing quality of rolling is supplied in the course of rolling craft experiment; The feeding quantity in Y direction can be modified, the condition was created for seeking the relationship between the feeding quantity in rolling and the surface quality of rolling workpieces in the course of rolling craft experiment; In the course of rolling , the adjustment of precise feeding quantity in Z direction can be realized, the control precision can be reached to 0.01mm, the quantity of rolling power can be measured by power-sensor, the feeding quantity and rolling power can be adjusted. Record rolling velocity、rolling power and time precisely, automatically produce the strength-time curved line、distance-time curved line etc. The bending moment supporting device eliminate the space between the ram and devotail slot and ensure the precise feeding quantity in Z direction while rolling; the deduction heating device and its control system ensure the plastic precise-processing machine has wide processing range, which can process the metal in the range from nonferrous metal to titanium alloy and fit the characteristic of multiple kinds of worpieces’ material in real processing.
The plastic precise-processing machine to metal plane is based on the draft characteristic and demand of the plastic and precise processing, compound with the working characteristic of hydraulic shaping machine. it is only the beginning of researching the plastic precise-processing machine to metal plane, and there still exist some difficulties to be solved in the following works: (1) The ram fixed on the shaping machine weighs high and has no jointed surface available, which makes the joint between shaping machine and the bending moment supporting device difficult;(2) The induction heating device heating workpiece by electromagnetic induction principle is used to heating clavate workpiece; the specialized induction heating device circle need to be designed if the deduction heating device was applied to fulfill instant heating to the plane layer and make the surface soft instantly;(3) The half close circuit control system is adopted in the feeding device in Z direction, which need to be changed to close circuit control system according to draft experiment demand if more precision and specialized device are needed. Although there exists these difficulties at present,It provides the design idea and design principle model supplied for the design of the plastic precise- processing specialized machine in the future.
