Design of mini interchanged rolling mill

Abstract

Dynamic Compression Plate (DCP) Is the most popular type of implant plate that facilitate compressing the fracture bone during implantation. However, the price of DCP is still expensive according to developing contries people. The price of DCP mostly related to its manufacturing that involved many machining processes. The proposed solution offered in this study was to change DCP manufacturing process mainly on the gliding holes making used by machining process to be the forming process. DCP-manufacturing process sequences that proposed was to be: a) making a hole on the plate, b) cutting lengthwise plates to size, c) bending the plate and d) making holes gliding. To bend the plate was used to performed by the press machine. This study introduced rolling process in order to bend the plate. Unfortunately, there was no rolling machine available in market to perform this process, it need to design the rolling machine. This study therefore conducted designing rolling machine required to bend the plate by rolling process prior to make the gliding holes. The rolling design was based on thickness reduction capacity of machine performed by flat roller. The design is limited with power of 3 horsepower electric motor. By mathematical calculations, the horsepower can used to reduce the plate by 0,42mm performing on the 316L stainless steel plate with dimensions of 50 mm in wide and 5 mm in thickness.
