title = "Effect of end angle of counterpunch on Y-shape hydroforming",
abstract = "The counterpunch is usually used to control the protrusion height and also to control the evolution of thickness and avoid over thinning in T-shape or Y-shape hydroforming. In this study, the process of hydroforming a Y-shape is conducted by experiments, in which tubular material used is stainless steel and has an outer diameter of 42mm. Three kinds of counterpunches with end angle of 70, 80 and 90-degree are used to investigate its influence on wall-thinning and the height of the protrusion. The results show that the minimum wall-thinning can be obtained with an end angle of 70-degree, while a higher effective protrusion height can be formed with the increase of end angle.",
