The development of an automatic barbed wire fabricating machine for community

Abstract

       This article presents the Automatic Barbed Wire Fabricating Machine (ABWFM). Currently, the group of produces the Barbed Wire Manually (BWM) was set up from many groups in local areas. But the product is not enough for requirement. This research is aim to construct the ABWFM and evaluate the appropriate speed of barbs wire assembly. The ABWFM consists of many parts as follows: 1) Wire feed roller, 2) Barbs wire assembly, 3) Cutting knife, 4) Wire strictness decrease unit, 5) Bobbin unit, 6) Traverse spindle, and 7) Power source and operating control units. In this study, barb wire with zinc coated and diameter of 2.0 mm is used. Similarly, the barb pitch and barb length are 10 cm and 2 cm, respectively. The results found that the suitable speeds of traverse spindle and barbs wire assembly are 79.4 and 27.6 RPM, respectively. Moreover, the produce capacity of the ABWFM is about 15.24 kg/h and electric power consumption is approximately 1.47 kWh. Compared with the BWM, the results indicated that the producing rate of ABWFM is higher than the BWM by about 8 times. For the investment cost, 15.95 tons of the barbed wire can be produced within 5 years and the payback period is about 1.287 years.
