伺服压力机由于其滑块运动灵活而得到了广泛的发展和研究。在实践中，压力机用户可以有利地利用一台伺服压力机来处理不同的冲压操作，如落料，拉伸，压印，压花等。本文研究了一种混合驱动伺服压力机机构。这种伺服压力机的机构是一个七杆机构，其自由度为“2”。压力机的两个输入环节分别由一个普通恒速电机和一个伺服变速电机驱动。提出了基于解析法的压力机机构尺寸综合方法。通过运动学分析，导出了产生特定滑枕运动的伺服电机的运动函数。最后给出了一个设计实例，表明可以将该方法应用于设计一种能够进行各种滑块运动的混合驱动压力机机构。这项工作为压力机机构设计者提供了一种尺寸综合的方法。实现了伺服压力机的滑枕运动灵活性，这为提高任何不同类型冲压操作的性能提供了显著的好处。ASME版权所有©2005
Servo presses are notably developed and studied nowadays out of their flexible ram motion. In practice, press users can advantageously utilize a single servo press to deal with different stamping operations such as blanking, drawing, coining, embossing, etc. In this paper, a hybrid-driven servo press mechanism is studied. The mechanism for such servo presses is a seven-bar linkage whose degree of freedom (DOF) is “2”. Two input links of the press mechanism are driven by one normal constant-speed motor and one servo variant-speed motor respectively. The dimensional synthesis of the press mechanism that is based on an analytical method is proposed. The motion function of the servomotor that generated a specified ram motion is derived by kinematic analysis. A design example is illustrated, and it shows that one could apply the proposed method to design a hybrid-driven press mechanism capable of carrying out various ram motions. This work contributes to press mechanism designers a method of dimensional synthesis. The ram motion flexibility of the servo press is achieved, and this provides significant benefit to improve the performance of any different kind of stamping operations.Copyright © 2005 by ASME
