introduction:one.The mold base is set up 1.measurement: Size measurement is an indispensable action in the mold assembly,In order to be able to confirm whether the precision of the workpiece processing meets the required standards. Avoid using parts that are not up to standard,To ensure that the mold to reduce unnecessary maintenance,To increase the life of mold production. 2.trim:The template is precision machined(milling.grinding.drill.lining.attack.Wire cut)It leaves a rough edge and a sharp Angle,The rough edges and sharp corners of each part must be removed before assembly. (1)Trimming of the mould:1.Basic trimming:Remove the rough edges and sharp edges of each part.

introduction: Defects caused by improper cooling after forging usually have the following types: 1.Cooling crack During the cooling process after forging,High thermal stress will occur inside the forging due to the excessive cooling rate,It may also be due to the structural transformation caused by greater organizational stress。If these stresses exceed the forgings strength limit,The forging produces smooth and elongated cooling cracks。 2.Network carbide When forging steel with high carbon content,If the forging temperature is high,The cooling rate is too slow,The carbide will be precipitated in a network along the grain boundary。Such as,bearing[bearing:bearing(“
