摘要:

基于喷射成形基本原理设计了热锻模精密喷射成形装置,阐述了其关键技术及模具成形特点。该装置冶炼系统采用高频感应炉,取消了中间包,钢水直接从熔炼炉中流出雾化,减少了温度损失和能量消耗;雾化喷嘴采用限制式、单环缝、垂直式结构,并设有6个辅助气孔;沉积系统使用陶瓷母模作为雾化液滴的沉积装置,并采用了水冷式接收器。蜗轮蜗杆传动系统可控制工作台的X向运动及接收器的Z向移动、旋转运动,通过喷嘴的偏置和3个自由度的组合,喷射成形模具可以形成矩形和回转体型面。该装置可用于各种小型回转体和矩形型腔模具的成形。初步试验结果表明:该装置具有结构简单、造价低、加热快、通用性强的特点,适合小型模具精密喷射成形的研究工作。

Abstract:

A precise spray forming device for hot forging dies was designed and fabricated based on spray forming principles. The key design points and working characteristics of the device were introduced. A high-frequency induction furnace was used to melt metals. The intermediate pot was removed and melted metals flowed out and atomized from the furnace to save energy. The novel atomizing nozzle was restrictive and vertical with a single chink and six auxiliary holes. Ceramic molds and water-cooling receiver were adopted in deposition system. The nozzle could be moved up and down in Z direction and the stage could be moved in X direction and rotated around Z axis. By the nozzle eccentricity and combination of three motions, spray formed dies with square or round cavities could be formed. The primary experiments show that the device has some advantages such as simple structure, low cost, heating fast and general etc., suitable for research work on precise spray forming of small work pieces.
