| Achieving automation is the major direction of Mechanical manufacturing technology development in the future and the main approach of Forging industry to upgrade technology and progress. It can improve the efficiency of the production greatly, ensure the quality of products, improve working environment and reduce the labor intensity.At present, artificial ink-jet method made lubrication poor effect and scale removal not completely, thus resulted the forging quality is not stable and die life is short. According these and combined with forging production process, the paper designed an automatic blowing ink-jet system, which can be used to improve the lubrication condition in the process of a crankshaft forging production and realize the automatic lubrication link in the process of crankshaft forging automation. The paper expounds the friction mechanism and the commonly used lubricants and predicts the possible defects in the die forging process, to put forward to design the spraying device for the purpose of improving spraying efficiency and the effect of spraying.Based on the conditions of the actual forging production and the overall automatic blowing ink-jet system given, the paper has designed overall structure, structure decorate and each the major institutional in the automatic ink-jet device, and also has designed the process and the automatic control system of the system.To ensure the reliable operation and function extension, the paper is using the current main stream pneumatic transmission technology and the PLC control technology to drive and control the system.After experimental test, the system can accomplish the work process, achieve the goal of removing scale and uniform ink and improve the production efficiency and the service life of mold. Such as good blowing clean effect, inkjet amount evenly dispersed and only 2s completed spraying at a time. The automatic blowing ink-jet system has low price, function extension ability, stable and reliable operation, etc. |
