The accurate processing of metal work piece plane mostly adopts abrasive machining technology in present, which has been mature processing ways and is used mostly in mechanical industry. However, the consume of emery wheel is unavoidable in the abrasive machining technology. In order to avoid the abrasive burning, the continuous supply of coolant is necessary. In the addition, it is the unsoluted difficulty until now that the paste and block of emery wheel make it difficult to continue in grinding nonferrous metal process.
The plastic and precise process technology for metal plane is the comprehensive applying for the metal plastic process technology and the precision process technology in the metal plane. According to the plastic deforming principle of metal under certain condition, metal would produce continuous and partial plastic deforming by rolling pressure, which change and improve the final surface quality and property.
The paper is the important component of overall research about serial and partial plastic-precise deforming and precise process, which is researched by my advisor-professor Song YuQuan. The paper is about the design plan of metal plane plastic and precise processing machine based on hydraulic shaping machine specified in professor Song YuQuan’s practical new type patent “the plastic and precise forming device”, that is to say, the taking the ram-moving of hydraulic shaping machine as X direction dynamic mechanism, the feeding movement of working platform as Y direction movement of the plastic and precise processing machine to metal plane, the feeding-movement device and its control system in Z direction are designed and produced by ourselves. Now, the control system in Z direction has already put the last hand to equip, and the reformation equipment of hydraulic shaping machine have already installed to adjust to try to complete. To turn into that technique productivity, it is necessary to research to manufacture special equipments of roller burnishing to plane. Professor Song put forward the innovation thought concerning the special equipments of roller burnishing to plane, that both ends of the tool machine can process at the same time and the tool machine can carry out the double direction to roller burnishing. Therefore, the basic plan and design idea of the plastic and precise processing machine for surface are specified. On the draft characteristic and demand of the plastic and precise processing, the plastic and precise processing machine for surface compounding with the working characteristic of hydraulic shaping machine is exploited by Professor Song's creative thought . This article is only the beginning of the tool machine design, so it still need a quantity of improvement, supplement and perfect work to turn into low price, automatic control, working steadily and excellent quality producing model machine.
On the premise data-collection and the appraisal of the research materials, the following works have been done in the paper. According to the domestic and international research results and the finished experiments , the craft parameters of roller burnishing processing are confirmed and the athletic quantity and characteristics of the roller burnishing craft are specified. On these grounds, I chose the drive form to fit the craft request, and specify the design project of the plastic and precise processing machine for surface; By contrasting the features of the rolling processing technology between the shaping processing technology, I confirm the overall machine structure of the plastic and precise processing machine for surface and draw stereoscopic assemble drawing, which base on the foundation of hydraulic shaping machine and combine professor Song's creative thought; I Carry on the design work of the hydraulic system of the plastic and precise processing machine for surface, and draw the system drawing of the hydraulic. I design the both pole piston hydraulic cylinder ,chosing the main component the hydraulic pump and valve etc in the same time; I Carry on the design work of the workbench transmission organ of the plastic and precise processing machine for surface, emphasising on the reformation equip of landscape orientation feed system to turn the number controls.
The plastic and precise processing machine for metal plane comprehensively uses mechanical technology、hydraulic technology、electric technology and computer technology. The primate movement in X direction is hydraulic to spread to move, which has some strongpoints ,such as,widely adjusting velocity range, the steady speed and the small impact at automatic transform direction time. 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 locomotion workbench in Y direction is realized by the number control way, Satisfying the accuracy request to landscape orientation feeding quantity in the roller burnishing process and coming true metered control to the feeding quantity, which 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, which the control precision can reach 0.01mm. The quantity of rolling power can be measured by power-sensor and the feeding quantity and rolling power can be adjusted. The plastic and precise processing machine for surface, which has the higher automatization degree, can precisely record rolling velocity、rolling power and time, automatically producing the strength-time curved line、distance-time curved line etc.
