设计了一种新型取胚机械手用瓶胚冷却装置,该冷却装置主要是对冷却销的结构和功能作进一步的改善,使冷却销附有叶片,通过设计新型冷却销驱动机构,使数十个,甚至上百个带有叶片的冷却销同步转动。文中对该新型冷却装置的结构和原理进行了分析。在该装置中,由于各个瓶胚和冷却销有相同的效应,因此对该装置的仿真分析,只需建立一个瓶胚和冷却销相对应的简化模型即可。利用建模软件SolidWorks和与其无缝集成的流体分析软件COSMOS-FloWorks,建立了该简化装置的有限元分析模型,分别对该装置在一定流量、不同转速和一定转速、不同流量下的冷却效果进行了瞬态仿真分析。通过显示冷却5 s后的瓶胚内表面温度场,表明该冷却装置与传统配有不转动的冷却销的冷却装置相比,该装置有更高的冷却效率和更好的冷却效果。结果还显示了冷却销的转速越高,流体的流量越大,瓶胚的冷却效率越高,冷却效果越好。
A new embryo cooling device for embryo manipulator is designed. The cooling device is mainly to further improve the structure and function of the cooling pin. The cooling pin is attached with blades. By designing a new cooling pin driving mechanism, dozens of , And even hundreds of cooling pins with blades rotate synchronously. The paper analyzes the structure and principle of the new cooling device. In this device, since each preform has the same effect as the cooling pin, the simulation analysis of the device requires only a simplified model of the preform and cooling pin. Using the modeling software SolidWorks and its seamlessly integrated fluid analysis software COSMOS-FloWorks, the finite element analysis model of the simplified device is established. The cooling effects of the device at a certain flow rate, different rotational speed and certain rotational speed and different flow rates are respectively carried out Transient simulation analysis. By showing the temperature field of the inner surface of the preform after 5 s of cooling, it shows that the cooling device has higher cooling efficiency and better cooling effect than a conventional cooling device with a non-rotating cooling pin. The results also show that the higher the cooling pin speed, the greater the fluid flow, the higher the cooling efficiency of the preform, the better the cooling effect.
