我厂生产的车辆用圆柱弹簧,原采用浸漆工艺,劳动条件差,占用面积大,生产不安全,不能满足弹簧生产线的节拍要求。为此,改用电泳涂漆新工艺。弹簧在电泳前,必须进行抛丸处理,挂钩前,必须把表面的油污清除干净。从挂簧、电泳前冲洗、电泳涂漆、电泳后冲洗、烘干、卸簧、输送到装箱发送,全部过程自动进行。其工艺过程如下图所示。
I plant the production of cylindrical springs, the original dipping process, poor working conditions, occupy a large area, the production is not safe, can not meet the spring production line beat requirements. To this end, instead of electrophoretic coating new technology. Springs before electrophoresis, shot blasting must be carried out before the hook, you must clean the surface of the oil. From hanging spring, electrophoresis before washing, electrophoretic painting, electrophoresis after washing, drying, unloading spring, delivered to the packing to send, the entire process automatically. The process shown below.
