[Abstract]:Valve conduit is an important part of internal combustion engine valve. In the whole valve operation, valve guide not only has a guiding role. With the development of powder metallurgy technology, iron based powder metallurgy technology is widely used in the manufacture of valve tubes. The new technology makes the whole manufacturing process convenient and automatic batch production, high material utilization rate and high production efficiency. Can effectively reduce the production costs and production process of energy and resource consumption. At this stage the domestic enterprises the entire manufacturing process of the valve duct automation level is low, the entire production line of material handling. Machine tool control is done manually, there is no corresponding material transfer and automatic operation equipment, and the field noise pollution and air pollution are serious. Therefore, an automation is developed for the oil-immersed packaging of valve duct. Flexible production line to reduce the labor intensity of workers and enhance the competitiveness of enterprises is of great practical value. The specific analysis of the existing production line work requirements, a careful study of the original equipment. Process and operation habits of the workers, determine the production line mechanical plan, design the production line automatic control flow. The whole production line by pipe feeding machine, oil dipping machine, separate conveyor. A series of equipments such as electronic scale are composed. The hardware scheme is designed and selected according to the determined control system, especially for the core components, PLC, touch screen. The servo motor and pneumatic components are considered in many aspects, carefully analyzed and calculated, and the appropriate model is finally determined. The design of the electrical control loop is carried out: the main circuit and the relay control circuit. PLC control circuit, AC servo servo system circuit, pneumatic circuit design, completed the design of the control cabinet. Based on the hardware scheme, designed the software structure of the control system. The communication between a single touch screen and three PLC is studied and realized, which is based on the idea of modular programming. The PLC program is designed and written. The touch screen program is designed to cooperate with the PLC program. After the overall design and assembly of the equipment is completed, the principle verification debugging and field debugging are carried out. A series of assembly and design problems have been corrected. Aiming at the indentation of the end surface of the pipe, the scheme has been upgraded and improved. The working sequence of each part of the equipment has been adjusted according to the different feeding requirements on the spot. Satisfied the production beat. Carried out the later maintenance, solved the problems in the production for a long time, formulated the later maintenance standard. At present, the pipe feeder works well, obtains the high praise, the enterprise prepares to popularize in a large area. A follow-up order has been obtained.
