Surfacing and stamping technology of flange

On May 4, after two months of hard work, the company's employees invested 10million yuan to build a welding workshop, and 11 flange sealing surfaces and pipe inner wall heap welding machines were successfully installed and debugged on site. As an economic and fast process for material surface modification, flange sealing surface surfacing and pipe inner wall surfacing are more and more widely used in oil, natural gas, CNOOC and other famous international engineering projects. Our company complies with the market demand and is committed to the development of new products. We believe that we will have a place in this field. The stamping of flange is a production measure. Compound die is adopted. The exception is multi position progressive die. Multi pass stamping technology operation can be completed on one press to complete the automatic generation of flange materials. The production speed is fast, the rest time is long, and the grinding cost is low. The collective can produce hundreds of pieces per minute, which is loved by many processing plants. Stamping parts have the characteristics of thin, uniform, light and strong strength with castings and forgings. The stamping of the flange can produce the workpiece with reinforcing ribs, ribs, bending or flanging that is difficult to manufacture by this skilled diameter, so as to improve its rigidity. Due to the rejection of rough dies, the workpiece accuracy can reach micron level, with high accuracy and consistent specifications, and can punch holes, sockets, bosses, etc. of flanges. In actual production, technological tests similar to the stamping process are often used to check the stamping performance of flange materials, such as drawing performance test and bulging performance test, so as to ensure the quality of finished products and high qualification rate. In addition to heavy plate forming by hydraulic press, the stamping equipment usually adopts the stagnation press. Focusing on the modern high-speed multi station stagnant press, it is possible to form a passive stamping production line with high production rate by setting up equipment configuration, such as uncoiling, finished product collection, escort, as well as the placement of die warehouse and quick die change, and using the computer French tube bundle. When tens or hundreds of stampings are produced every minute, the stamping and production processes are completed in a short time, and personal, equipment and quality problems often occur. Therefore, the production of flange stamping is a very important issue. But we mainly produce forged flanges instead of stamped flanges.
