密封橡胶件是制造变压器不可缺少的零件,小型变压器至大型变压器的外部密封连接少则十几种,多则二十到三十多种规格形状尽寸不等的密封橡胶件。以前我们制作平板圆形橡胶件采用冲剪制作,因此冲模规格繁多,模具制造成本费用高,特别是对平板圆形尺寸较大的橡胶密卦件用量少,冲模利用率低,制作成本高。为了提高工效,降低密封件冲模制作成本,我厂从改进工艺人手,由冲剪制作工艺改为旋转制作工艺,因此,我们设计一副平板圆形橡胶密封件旋转刀具,它可以制作由Φ50～Φ350mm Sealed rubber parts is indispensable to the manufacture of transformers parts, small transformers to large transformers sealed as many as a dozen external connections, as many as 20 to 30 kinds of specifications ranging from the size of the seal rubber parts. In the past, we made flat round rubber parts by punching and cutting, so the punching mold has many specifications and the cost of mold making is high, especially for the rubber plate with larger circular plate size, less usage of the punching die, low utilization of die and high production cost . In order to improve work efficiency, reduce the production cost of the seal die, I plant from the improvement of manpower, from punching production process to rotary production process, therefore, we design a flat round rubber seal rotating tool, it can be made by Φ50 ~ Φ350mm
