Due to its high production flexibility, roller hemming has become the mainstream process for forming and joining metal sheets in automotive industry. The traditional requires specific dies support sheet parts repeated offline manual adjustment of routes, resulting die costs, time consumption, excessive labor inputs. universal platform presented this paper could replace effectively reduce costs ...

Robotic roller hemming is currently one of the most used solution for joining metal sheets in automotive industry, especially those production lines which need to favor flexibility with respect raw productivity and mostly employed assemble car doors. Hemming a fairly delicate process since it does not only suffice technical requirement – join two panels together but also an aesthetical one, joi...

To realize the roller forming process of curved edges aluminium alloy auto-body closure panels, a numerical simulation method is proposed for sheet with adhesive in flat variable curvature. Firstly, motion calculated by discrete curvature curve method. Secondly, FEM-SPH coupling established to simulate interaction between layer and sheet. Subsequently, model was constructed finite element calcu...

In this article, new techniques and technologies have been tried and tested in the installation and commissioning of Roller Home industrial robots, in order to produce a Tiba car with a focus on cost reduction. Due to the fact that press equipment for automobile parts requires a lot of expenses, it was decided to use robots with the same function of roller to reduce costs and increase the q...

Hemming is a three-step sheet-folding process utilized in the production of automotive closures. It has a critical impact on the performance and perceived quality of assembled vehicles. Using a two-dimensional finite element model, this paper presents a design-of-experiments (DOE) study of the relationships between important hemming process parameters and hem quality for aluminium alloy AA 6111...

Abstract Accurate quantification of external force is the key to improve high-precision hemming autobody closure panels. However, mechanism on forming quality complex contour sheet metal with adhesive not clear subjected geometric curvature and materials. In present study, taking curved edge aluminum as research object, SPH (smooth particle hydrodynamics) introduced simulate viscous adhesive, S...
