Abstract
Research on Inner Surface of Tubes Hydroformed
Highlights
Hydroforming is a manufacturing process that uses hydraulic pressure to produce the straining of a blank sheet or a tubular part
EXPERIMENTAL RESEARCH This paper aims at determining the roughness of the tube surfaces before and after hydroforming
Tube hydroforming processes is a new and advanced method the manufacturing tube parts, and it has a wide range of applications, being used in the automotive industry
Summary
Hydroforming is a manufacturing process that uses hydraulic pressure to produce the straining of a blank sheet or a tubular part. Hydroforming has an important role in the automotive industry due to its capability to produce stiff components with hollow configurations. This combination of characteristics leads to lighter and more rigid vehicle constructions. Tubular hydroforming method is frequently used to make complex parts at the structure of automotive and in the other sectors of manufacturing (aeronautical parts, industrial parts). This method is a cold deforming process, and we can obtain the form that we want by one single operation. The qualified parts can be obtained in each process by optimising the parameters in the process of loading [2]
