模內切製杯機之設計與開發

Design of the manufacturing internal cutting cups mold machine

指導教授 : 王金樹

摘要


在以往的塑膠模製杯機幾乎都是先以抽氣成型製成杯子以後再送到裁切機做裁切的動作,整個機台的體積會相對的比較大,同時過程也相對的比較久一點;為了使杯子更有效率的製作出來,我們希望在模子內部抽氣的時候同時可以做裁切的動作,要達成這個動作就需要有可以做變化加速度的能力。因此本文之設計重點在於可變化加速度的凸輪,在最少輸入動力的情況下可以完成模子內部裁切的目的。   本論文主要是利用機構設計的向量迴路再加上所選定的凸輪路徑,配合運動學中的位置分析來找出凸輪的輪廓,以及牛頓定律來找出各桿件的內應力,並且將整個機台作模組化的動作,改變任一桿件長度可得到不同的凸輪輪廓但是不影響其模具的運動,這樣可以減少在電腦設計部分的改圖、量測的時間,並且可以將專用機台系統化,讓使用者可以依照個人需求來選擇機台大小的變化。最後我們將設計好的機台創新變形,讓機台變得更多元性,不同的變形有不同的運動方式。整個設計流程讓機台製作系統化、機台設計完整化、機台的使用多元化。

In general, a plastic cup runs exhaust molding with plastic molded cup machines prior to cutting with a cutting machine. Consequently, the process is relatively long and volume of the whole system is relatively large. To be more efficient, the improved process combines exhaust and cutting into a single machine which can be done by varying acceleration with time. In this thesis, we propose a design of an accelerating cam to accomplish cutting inside the mold with minimum power consumption. The profile of the cams is determined with a selected cam curve and position analysis. It is calculated by the vector loop from mechanical design. Newton's law is then applied to find out the internal stress of each bar. When the machine is modularized, giving different bar length can have corresponding cam profile without affecting mold movement. As a result, the machine is highly customizable for variant user needs. It speeds up the diagram modification and simulation in computer design In addition, we innovate a machine transformation which gives it diverse motion. In conclusion, our design process supports the systematic machine production, the integrated machine design, the diversified use of the machine.
