The Overall Structure Design Of The Automatic Cutting Machine For Aluminum Tubes By Multitool Coreless Punching Type And The Study On The Key Technology

Automotive air conditioning system is an indispensable part of automobile, as one of the main automobile comfort assembly, provide the automobile refrigeration, heating, defrosting, defrosting, air filtration and humidity control function. But in automobile air conditioner condenser, evaporator and connecting pipelines need to use a large number of tubes. So the aluminum to achieve high precision, high efficiency and low cost of processing, this is a very good way to reduce the production cost of automobile manufacturers.The cutting machine on the market was analyzed in this paper, and the shortages of existing cutting solution were pointed out, and then a new cutting scheme aimed at these deficiencies was put forward. The pneumatic method without mandrel cutting was adopted in the scheme, which realized rapid and efficient cutting.Yet this way of cutting in the domestic market has not appeared, which was just a research and development project. The multiple blade coreless cutting type aluminum pipe cutting machine overall structure and design was carried on the detailed introduction in this article, including the design of the raw material sorting structure, push feeding structure, servo feeding structure, automatic conveying structure and blow crumbs chamfering organization structure.According to the theory of mechanical movement and mechanical structure design, the3D software SolidWorks was used in establishing3D model of cutting machine and then the whole structure principle and movement principle of each part could be analyzed, at last the structural design of the cutter could be checked further. Its unreasonable structure need to be improved to make it more simple and reasonable, and also the quality of aluminium on the surface of the pipe and the production efficiency could be improved at the same time, anthe working noise could be reduced, safety coefficient could be improved.At the same time, the factors that affect many knives coreless type aluminum pipe cutting machine were analyzed in this article. There are many kinds of factors affecting the quality of aluminium tube incision in the cutting process of aluminum tube, but the cutting mode, the shape of the cutter, cutting clearance and cutting speed is the main factor.The metal Deform finite element analysis software was carried on the dynamic of the cutting process of aluminum tube simulation analysis in this article.It can analyze the force of the tube and the tool. At the same time, the single-pole cutting solutions and more knife cutting incision solutions were made, which can make a comparison in aluminum tube cross section quality and the service life of the punch knife, and the superiority of the design scheme of die cutting was explained.
