Content summary: The article basically discusses a stage to amount to product of transducer, PLC, HMI to be in muti_function the applied principle of system of control of press coming back, in this system, the whirl of electric machinery of transducer drive main shaft; PLC adjusts with RS-485 communication means main shaft (transducer) rotate speed, PLC imitate quantity expands module is used at controlling the pressure of hydraulic pressure crock and flow, coder gets left hydraulic pressure crock and on the right side of the current position signal of hydraulic pressure crock, the moving condition of HMI monitoring press coming back and alarm information, the system that revealed a stage to amount to automation product is compositive advantage. 1 foreword comes back press a technology, also call a metal to come back press figuration technology, the dot getting power that makes through rotating arrives by the line to the line by the dot face, give constant pressure to make metallic stuff is out of shape along this one direction in a certain direction at the same time shape with flow the technology of some appearance. Here, metallic stuff must have plasticity to be out of shape or performance of going from place to place, come back press figuration to differ to be out of shape with plasticity, it is collect plasticity is out of shape with metabolic of going from place to place complex process, what special need points out is, what we say come back pressing figuration technology is not onefold puissant come back press and common come back pressure, it is both union. Come back pressing is secure flat or hollow preform the mould in press coming back to go up, while preform follows machine tool main shaft to turn, use spinning roller or drive marvellous pressurization at preform, the plasticity with made local generation is out of shape. In the whirligig of the feed motion of spinning roller and preform joint action falls, make local plasticity is out of shape progressively ground expands the whole face of preform, clingy at the mould, of the spare parts that finish come back press treatment. Come back the good point that approachs leather belt annulus and casting iron sheet to take round of photograph to compare is to use come back press craft to be made () of the treatment that do not have bits, structure material of light, province, moment of inertia is consequently small, it is makings of a kind of section, energy-saving new product. Manufacturing efficiency is tall (minutely treatment 2 ～ 4) , balance performance is good, need not balance processing commonly. Because material streamline is not cut off, exterior production is cold make sclerosis, constituent density rises, make the intensity of round of groove surface and hardness rise, and dimension precision is tall, v-belt and annulus slippery difference of groove is little, leather belt life is long. What 2 technology control asks the article introduces is muti_function press coming back is used at the production, car leather belt that processes all sorts of type annulus, the car leather belt that adjusts equipment of technological process, change to run parameter to machine different specifications through be in feeling screen annulus.
