我厂生产的外灯座,是前后信号灯的主要部件,材料为08冷轧板,厚度0.6毫米。其颈部尺寸很重要,它关系到灯具的密封性与牢固性,原生产需八道工序。如图1所示。 平均每月生产量7万件,由于二次缩口工序,颈高达不到2.5~(+0.8)毫米,(且颈根R大,周边不齐)与灯亮铆合时搭边小,牢固性与密封性也差,有少数产品还需人工敲平。我们从改进工艺着手,将原来的八道工序改为六道工序,如图2,节省了两道工序,节约了工时,减少了模修费用。经鉴定,产品符合技术要求,现已按新工艺生产了21万件。模具结构示意如图3。
The outer lamp holder produced by our factory is the main part of the front and rear signal lights. The material is 08 cold-rolled plate, the thickness is 0.6mm. Its neck size is very important, it is related to the tightness and firmness of lamps and lanterns, the original production needs eight processes. As shown in Figure 1. The average monthly production of 70,000, due to the second shrinking process, the neck up to less than 2.5 ~ (+0.8) mm, (and the large neck R, the surrounding irregularity) And the sealing is poor, there are a few products need manual knocking. We start from improving the process, the original eight processes into six processes, shown in Figure 2, saving two processes, saving man hours, reducing the cost of mold repair. Identified, the product meets the technical requirements, has now produced 210,000 pieces of new technology. Mold structure shown in Figure 3.
