Abstract

The aim of this work is to evaluate the possibility of inexpensively producing small-batch polymer sheet components using robotized single point incremental forming (SPIF) without backing plate support. An innovative method of thermal and ultrasound assisted deformation of a polymer sheet is proposed using a tool with a sphere mounted in a ring-shaped magnetic holder, the friction of which with the tool holder is reduced by ultrasound, and the heating is performed by a laser. The heated tool moving on the sheet surface locally increases the plasticity of the polyvinyl chloride (PVC) polymer in the contact zone with less deforming force does not reducing the stiffness of the polymer around the tool contact area and eliminating the need for a backing plate. The free 3D rotating ball also changes the slip of the tool on the surface of the polymer sheet by the rolling, thereby improving the surface quality of the product. The finite element method (FEM) allowed the virtual evaluation of the deformation parameters of the SPIF. Significant process parameters were found, and the behavior of the heated polymer sheet was determined.

摘要

这项工作的目的是评估在没有垫板支撑的情况下，使用机器人单点增量成型（SPIF）廉价生产小批量聚合物板材部件的可能性。提出了一种创新的聚合物板材热超声辅助变形方法，该方法使用安装在环形磁性夹具中的带有球体的工具，通过超声降低工具与夹具之间的摩擦力，并通过激光进行加热。在板材表面移动的加热工具在接触区域局部提高聚氯乙烯（PVC）聚合物的可塑性，以较小的变形力在不降低工具接触区域周围聚合物刚度的情况下，消除了对垫板的需求。自由的3D旋转球还通过滚动改变工具在聚合物板材表面的滑动，从而提高产品的表面质量。有限元方法（FEM）允许对SPIF的变形参数进行虚拟评估。找到了重要的工艺参数，并确定了加热聚合物板材的行为。
