介绍了一种基于机构组合的新型锻造夹持机构,应用联立约束法建立新夹持机构的力学模型,利用反作用力响应盲区的概念对新机构的承载能力进行进一步的分析,建立ADAMS动力学模型,对新旧机构在水平和垂直夹持两个位置时夹持机构夹持力进行比较,计算结果与模拟结果一致。最后通过现场实验证明:新夹钳在锻件垂直位置比原夹钳能够减少至少一半的油缸推力,显著提高了巨型重载夹持机构的承载能力。为巨型重载夹持机构的设计提供了一种思路。
A new type of forging clamping mechanism based on mechanism combination is introduced. The mechanical model of the new clamping mechanism is established by using the simultaneous constraint method. The concept of reactive force response dead zone is used to further analyze the bearing capacity of the new mechanism. The ADAMS dynamics Model, comparing the clamping force of the clamping mechanism between the old and the new mechanism in the horizontal and vertical clamping two positions, the calculation results are consistent with the simulation results. Finally, field experiments show that the new clamp can reduce the thrust of the cylinder by at least half compared with the original clamp in the vertical position of the forging, and significantly improve the carrying capacity of the giant heavy-duty clamp mechanism. It provides an idea for the design of giant overloaded clamping mechanism.
