摘　　要：皮革裁剪是皮革加工流程中一道关键工序,在诸多皮革裁剪中,电动式皮革裁剪以方便、高效等特性提高了皮革裁剪的效率,但电动式裁剪亦存在噪声大、切割精度低等缺点。针对电动式皮革裁剪存在的振动噪声大、切割精度低等问题,通过提供一种电动式皮革裁剪头的设计方案,分析了影响其振动噪声、切割速度、切割精度的因素;对设计模型进行了运动学仿真,分析了刀头部分的运动状况、产生动不平衡的原因及改进方法;使用ANSYS软件,对伸缩杆进行了受力分析,得到了伸缩杆的受力情况。研究结果表明,电动工皮革裁剪产生的振动噪声与惯性力有关,而惯性力的产生源于动不平衡性,此外伸缩杆的受力变形会影响切割精度。Leather cutting is a key process in leather processing.Electrodynamic leather cutting mechanism improves the efficiency of the leather cutting with its characteristics of convenient and efficient,but electrodynamic leather cutting mechanism is shortcomings of large noise and low accuracy of cutting.In order to analyze the factors of affecting vibration noise,cutting speed and cutting precision,one kind of design of leather cutting mechanism was offered.Through the kinematics simulation,the movement of cutting head,the reasons for dynamic unbalance and the improvement methods have been obtained.With the ANSYS,the stress distribution of the telescopic rod has been received.The results indicate that the vibration noise is related to the inertial force,and the inertial force produced is the result of dynamic unbalance.In addition,the mechanical deformation of the telescopic rod will affect the cutting precision.
