A dowel pin puller in simple word is a hand tool that is used to remove dowel pin that has been tapered from their insertion holes. Using the various head sizes, the tool threads into the extractable dowel pin and pulls it out using the slide hammer technique. Meanwhile, dowel pins are a type of industrial fastener that is used to connect two or more products. Therefore, in this project, a durable and affordable dowel pin puller that can reduce set up time during production is designed and fabricated. During the earlier stages of design, a PDS and DFMA guidelines is constructed based on the datum to set a range for the design. Then, after the conceptual design had been sketch, the approach of concept scoring matrix is used to select one of the best designs, where design A is selected. SOLIDWORKS software is then being used to detail out the design and for design analysis, FEM. As result, the safety factor for the parts that been simulated, is greater than 2, which is acceptable and safe. A survey also conducted during design analysis to get the feedback from expert, and user, where most than half of the respondents were chosen and satisfied with the design A, as in the selection of matrix. Thus, design A is fabricated. The dowel pin puller is made of main materials which is low carbon steel and costed RM95.80 for fabrication cost. In conclusion, the objective, and scope of the project is achieved, and the design is successfully fabricated within the period of time. For future works, more improvement can be made for the design in terms of feature, and safety to make it more attractive and functionality.
