热喷焊是近几年来新发展的一项表面处理新技术,但是,目前在实际生产中,还大多是以手工操作为主,劳动条件差,生产效率低。为了解决这个问题,我们按照氧-乙炔焰的一步法、二步法喷焊工艺要求,自行研制了SJD-2型自动喷焊机。该机不但适用于采油(气)井口装置平板阀、环形密封零件及轴类易损、易蚀零件的喷焊,而且还适用于注塑机进料变螺距螺杆的粉末等离子弧喷焊。由于SJD-2型自动喷焊机变速调节范围大,喷焊不同产品的适应性强,另外再加上具有数字记忆装置,所以能确保产品质量。该机通过一年多的试生产证明:设计完全符合工艺要求,是国内较完善的一台自
Thermal spray welding is a new surface treatment technology newly developed in recent years. However, most of the actual production is mainly manual operation with poor working conditions and low production efficiency. In order to solve this problem, we developed the SJD-2 automatic welding machine according to the one-step oxy-acetylene flame and the two-step spray process. The machine is not only suitable for oil and gas (gas) wellhead flat-plate valve, ring seal parts and shaft vulnerable, easily eroded parts of the spray welding, but also for injection molding machine variable pitch screw powder plasma arc welding. SJD-2 automatic spray welding machine as a result of variable speed adjustment range, spray welding adaptability of different products, combined with a digital memory device, so to ensure product quality. The machine passed the trial of more than a year to prove that: the design fully meets the technical requirements, is a more perfect self
