Blanking punch contents is a derivative sales, and guarantee the workpiece and the shape of the holes in the relative position accurately, improve processing accuracy. 落料凸模内装有导正销,保证了工件上孔和外形的相对位置准确,提高了加工精度。
After that the author did the simulation of corrugated boxes in the compressive strength under different humidity and different punch position changes based on the ANSYS software. 然后在Ansys软件中通过瓦楞纸箱的建模,加载,网格划分,求解等仿真模拟瓦楞纸箱在不同的打孔位置下的抗压强度的变化。
The author researched the trends and changes in the degree of compressive strength of corrugated boxes with the humidity and punch position changing. 研究出随着湿度和打孔位置的变化,瓦楞纸箱抗压强度的变化趋势及变化程度。
