Afegir etiqueta | Sumari: | A machine design and building was objective of this project for the application of chrome effect paint on metal and plastic surface parts, supporting the company Maquilu needs, which chose to implement the chemical chrome plating method that provides a metallic and mirror-like appearance manually, due to the economic factor. However, the main drawback that arose in the company when implementing this method is the time, used to perform the process, which leads to low chromed parts production. For this work development, a qualitative and quantitative methodology was used, which helped to have a machine design and building complete vision. Regarding its building and operation, the machine uses a rotating plate that supports a maximum load of 25 kg and rotates at an optimum working speed of 24.7 rpm determined by an experimental analysis; obtaining this speed in the machine, a system of pulleys and belts connected to an electric motor of 1540 rpm was implemented; to carry out the application process, a pneumatic distribution system was used to meet the needs of the machine. To carry out the experimental tests, a piece with an area of 0.055 m2 was taken into consideration, and by means of the proportions table, the exact quantities of the chemical compounds for the proposed area were determined. The spray guns were calibrated at 2.5 bars in order to avoid over application and waste of the chemical compounds. In addition, the machine allowed the operator to perform the process in half the time compared to the previous method, which means an increase in the final production parts with good results. |
