Related requirements for elbow machining quality and comprehensive mechanical properties:
1. Bend machine series hot pushing elbow outer arc tensile plastic deformation is larger, the normal temperature, high temperature yield strength and tensile strength increases, plasticity and significantly lower back and toughness, so should make more reasonable production process, strict control of bend hole enlargement ratio, reducing elbow outer arc tensile plastic deformation, in order to obtain comprehensive mechanical properties.
2. The inner arc wall thickness of hot pushed elbow made by elbow machine does not increase, and the inner arc is exactly the high stress area of elbow. In order to ensure that the inner arc wall thickness of elbow meets the standard requirements of the product, pipe billet with appropriately thickened wall thickness should be selected for pushing.
3. The hot push elbow can produce axial bending deformation and radial expansion during the forming process, so special attention should be paid to check whether cracks, microcracks and intergranular cracks occur on the inner and outer walls of the elbow.
