Implementación de un prototipo mecánico para medir la resistencia a la rotura de la flor de cuero (Lastómetro)

Abstract

At ¨ Velasquez and children¨ construction company, it was developed the desing and construction of a mechanical prototype lastometry, for its validation some tests were developed either at the Laboratory of quality control from the ANCE as in ESPOCH which constituted the experimental units and the results obtained were compared using descriptive statistics in order to determine if there are any differences between laboratories. For instance, it is said that for the construction and implementation of the mechanical prototype, high quality materials were used in order to make sure the precision in the essay as well as the application of the manufacturing technique and the equipment power record was 559,25 watts, since the efficiency of the machine was 80%. In the evaluation of physical resistance of the leather, it was determined that when tanning the fur, the thickness of the leather is better (1,12mm), lastometry (10,06 mm) and time for breakage (1,01 s) which was obtained when tanning leather with chrome meanwhile the highest resistance to tension is (1809,83 N/cm2) and a percentage of lengthen (62,50 %) was registered when tanning leather with vegetables. It is claimed that the construction and implementation of the equipment kept a high quality protocol which is competitive for national industry. The production costs of over 3117 American dollars are lower to those registered in the national and international budgets which state a price of 10000 dollars, this represents a meaningful reduction in manufacturing and satisfactory precision results.
