There are many reasons for forging quality problems. Through macro and micro analysis of forgings, simulation tests are sometimes required to determine whether it is the forging process itself or other influencing factors (such as raw materials, heat treatment, surface treatment or test errors); Only after careful study and analysis can forging be obtained.
More +The forging process is complex and there are many forging fires. The forging process of forgings basically includes all free forging processes. Due to the heavy weight of forgings, ingot blanking, billet head, punching and intermediate mandrel stretching must match each other to ensure the size of forgings.
Forging is a processing method that uses forging machinery to exert pressure on metal blank to produce plastic deformation and obtain forgings with certain mechanical properties, shape and size. It is one of two parts of the forging pressure (forging and stamping). Forging can eliminate defects such as loose metal casting in smelting process and optimize microstructure.
The medium frequency dual frequency induction heating of aluminum alloy forgings is continuous heating from bottom to top by using a circular inductor and spraying quenching water at the same time. Cold roll, piston, cement grinding wheel, etc. Especially for long forgings, due to the limited length, the quenching machine cannot be used for vertical lifting. Special sensors and transformers can be used for shaft crawling or sliding along the guide rails, only for horizontal placement.
Aluminum alloy forging includes A1 Si Mg Cu alloy and A1 Cu Ni Fe alloy. Common forged aluminum alloys include LD2.LD5.LDL0, etc. They contain a variety of alloy elements, but the content is small. They have good thermoplasticity, so they have good forging properties and good mechanical properties.
The brake caliper is used to clamp the brake disc to generate braking force. Its relatively rotating brake disc is fixed. When you step on the brake, it clamps the brake disc to decelerate or stop.
