A diagram designed to adapt the parts to the requirements of the forging parts process. It is drawn on the basis of the part drawing, with machining allowances and forging tolerances added. The forging diagram is divided into cold forging diagram and hot forging diagram.
The commonly referred to forging diagram refers to the cold forging diagram. The cold forging drawing is the basis for formulating forging process regulations, accepting forgings, designing inspection fixtures, and machining fixtures. The hot forging diagram is designed based on the cold forging diagram by adding thermal expansion, and it is the basis for designing and manufacturing forging molds and trimming dies.
The design of forging drawings should consider the machining allowance and forging tolerance of forgings, determine the parting position, namely the parting surface, forging slope, forging fillet radius, and punching connection.
