Abstract


1. With the improvement of the people’s living standard, people require better and better furniture and decorations at home. So the usage of pneumatic line-up nail is inestimable and its manufacture has a brilliant future. The simplification of the equipment, qualified products, the extension of service life and the automatic manufacture flows will be a tendencv in the future.2. As a result of the market expansion, more and more people invest in nail manufacturing. The competition is quite severe. Who will win the market depends on its production efficiency, which is essential to improve the enterprise benefit.3. At present, it is urgent to design a better automatic nail machine with high efficiency. The productivity of former machine 50-70 pieces per minute (100 is one piece) now the new ones 160 pieces per minute. Especially, the new machine is simple, efficient, reliable, universal and low cost.4. Because the engine block of the pneumatic line-up nail machine is the weld joint and the weldment is easy to distort. The distorted pedestal will make adjustment difficult. which requires carefully polishing and shutting down the engine lathe. And all of the above consumes investment and time. The unreasonable design also causes the stress concentration and fracture in certain part and as a result the danger exists now and then. What’s more, the hydraulic cylinder and the connecting rod between tools are out of order and difficult to meet the requirement.Through the analysis, we’ll change the weld joint into cast steel ZG270-500 (original trademark is ZG35). In this way. it is convenient to adjust the tools for different product types and it can also reduce the distortion in its operation.After the improvement. it will double the output and prolong the machine life, which will enhance the enterprise’s competition greatly and produce a great influence in nail manufacturing.
