ANALISA PENGARUH SPRINGBACK TERHADAP SUDUT TEKUK PADA PROSES PENEKUKAN PELAT ALUMINIUM

Abstract

ABSTRACT

The process of bending is one type of metal forming processes are widely applied in manufacturing. The process of bending is particularly prevalent in the metal material that is widely used in daily life. More expect precision bending process in order to get a shape corresponding to the desired. In the process of bending will be a force behind the phenomenon called springback phenomenon. Aluminum plate is one of the widely used materials of everyday life.

Springback is the force behind the effect caused by the elasticity of the plate material is process of formation. The force behind this price is determined by the modulus of elasticity of the material. In this bending process springbok must to be consider.

Type of research conducted is descriptive, a study aimed to describe a situation or phenomenon is. Research is carried on an existing phenomenon in order to draw conclusions from the existing phenomena.

Results revealed that there is a difference of bending process turning the corner on the corner of 45° studies with 90° angle where on the corner of 45° if the note chart tends to fall while in the corner of the 90° tends to rise the difference is due to differences in tensile and compressive force when bending angles of 45° and 90° while the bending angle, the optimal angle showed large bending or bending angle is used to obtain the results of bend 45 ° is 143 °, and the bending process results in the optimal angle showed large bending or bending angle is used to obtain the results of 90 ° bend is 96 ° the conclusions obtained from the study of the bending angle is given the greater the turning angle is obtained.

Keywords: angle bending, springback and bending angle results.
