The manufacturing process of the surface rust removal of small pressure vessels belongs to the technical field of refrigeration equipment. The present invention by steel casting into both ends of the cylinder body and cylinder cover, which is characterized in that: firstly, the cylinder through shot peening surface treatment, were shot by shot blasting machine, cylinder body by a hanging overhanging support into the shot blasting machine, shot after the surface of the cylinder body of the dirt, rust and so on is cleared and then, on the surface; the end cover and the copper pipe to connect copper steel welding to form copper steel through a workpiece clamping and fixing a workpiece chuck with rotating with copper steel workpiece chuck by a support plate supporting sandblasting sandblasting machine is installed in the cavity, supporting the workpiece chuck with support plate with dribbling revolution by blasting, sandblasting machine. Through blasting technology, blasting process and other physical methods of tube and copper steel binder surface and the weld surface rust treatment, make the surface of the cylinder body and the copper steel with surface welding and formed the pitting to improve paint adhesion.

小型压力容器表面除锈制造工艺
本专利技术属于制冷设备
,尤其与一种小型压力容器表面除锈制造工艺有关。
技术介绍
常见的制冷设备中,如油液分离器、汽液分离器、消音器、储液器等小型压力容器,通常包括由钢材制成的筒体以及筒体两端的端盖,两端盖上分别设置有输入孔和输出孔,输入孔和输出孔上焊接有铜连接管,现有的小型压力容器的制造方法分为三步:首先,钢材制成的筒体和端盖经过盐酸酸洗、两道清水清洗、防锈液浸泡及晾干;然后,将端盖与铜连接管焊接形成铜钢结合件,铜钢结合件经过热水除油、两道清水漂洗、盐酸酸洗、(Hcl+H2SO4+H2NO3)组合液酸洗、清水漂洗、铬酸酸洗、两道清水清洗、NaOH中和、两道清水清洗、防锈液浸泡及烘干;最后,将筒体与铜钢结合件焊接后形成整体,在端盖与筒体外侧面上的台阶处进行二氧化碳保护焊,整体进行磷化处理,在表面形成结晶麻点,进行喷漆。现有这种制造方法存在工序繁多复杂,化学处理存在安全隐患、生产效率较低,污染环境等缺陷。

【技术保护点】
小型压力容器表面除锈制造工艺,通过钢铁铸造成型成筒体和筒体两端的端盖,其特征在于:首先,筒体通过喷丸工艺进行表面处理,采用抛丸机进行抛丸,筒体由一挂具悬伸支撑放入抛丸机中,抛丸后筒体表面的污物、锈迹等被清理,而且表面形成麻点;然后,端盖与铜连接管焊接形成铜钢件,铜钢件通过一工件夹头夹持固定并由工件夹头带同铜钢件旋转,工件夹头由一支撑盘支撑安装于喷砂机的喷砂腔内,支撑盘带同工件夹头随支撑盘公转,采用喷砂机进行喷砂。
