Improvement of the Stainless Steel Elbow Pressing Process

　　Stainless steel elbows are widely used in petrochemical, instrumentation, food, and other industries because of their good corrosion resistance. For professional pipe fittings manufacturers, stainless steel elbows are a high-value-added product, and their quality and output directly affect the benefits of the enterprise

　　To ensure that the elbow is fully formed, the process requires that a core and a horseshoe must be placed in the pipe joint during pressing. Its structure is complex and processing is difficult.

　　From the deformation characteristics of the pipe, it can be seen that the bending force acts along the radial direction of the pipe fitting surface, and the stress generated on the pipe fitting surface is very large, causing the unfilled section in the pipe to sag, resulting in one-time forming of the elbow Not good, increased repair time and cost.

　　During the pressing process, the inner and outer arcs of the pipe are prone to bulges and depressions, making it difficult to remove the core and horseshoe placed inside the pipe after the pressing is completed, which increases the auxiliary time spent on removing the core, reducing production efficiency. From the above analysis, it can be seen that the above defects will inevitably appear in this process, and if the deformation is carried out along the axial direction, this problem can be better solved in terms of form. Therefore, axial deformation can be considered. Pressing process.
