多條線材同時進行扁平輥壓加工之研究

扁平輥壓加工是將具有圓形斷面之鐵線，通過壓平輥輪，利用冷輥製方式，輥製成所需厚度之板條。本研究是針對多條線材同時進行扁平輥壓加工行為，將輥輪假設為剛體，利用DEFORM 3D有限元素分析軟體進行模擬；經由電腦模擬，探討單條及多條線材同時進行扁平輥壓加工之等效應力、等效應變的分佈、輥輪所受的成形力、加工過程中輥輪的彈性變形、加工前線材直徑與加工後材料高度對成形力的影響，以作為線材排列間距設計及輥輪設計之依據

In wire flat rolling, wire of circular cross-section is cold rolled between the flat rolls in one pass to achieve the desired thickness. This study is pointed the rolling process behavior of wood working strip nails, analysis the material condition under the flat rolling process of multi- wires, by using the DEFORM finite element analysis software with the rigid-plastic deformation model. From the computer simulation results, we can understand the contact pressure variation between the wire and roller, the relation between the contact width and the height reduction ratio, the effect of the rolling speed and material property to the side spread. These information can be assisted the design of the roller and the distance between wires.
