Correct Inspection Method of Die Forging Size

Correct inspection method of die forging size
When using a die forging die, the metal structure can be changed and the metal properties can be improved, so that the internal properties are compact, uniform, fine, integral and reliable. After the die forging is deformed by hot forging, the metal is a fibrous structure, and its metal flows plastically in it. To have the desired shape, when the metal flows plastically under an external force, the volume does not change and the metal always flows towards the partial resistance.
In production, the shape of the workpiece is usually controlled according to these rules, and deformation such as defects, bending and stretching will occur, the size of the workpiece, which is beneficial to mass production, die forging, extrusion, stamping and other applications Die size and stability, high-efficiency die forging machines and automatic die forging production lines can be used to organize high-volume or high-volume professional production, the process of die forging production, including die forging cuts before forming, die forging blanks and heat treatment of them And pretreatment, heat treatment after molding, cleaning, correction and inspection.
Commonly used die forging machines are forging hammers, hydraulic presses and mechanical presses. The hammer has a high impact speed, which is good for the flow of plastic metal, but it will generate vibration. The hydraulic press is made of static die forgings, which is beneficial to Die forging metal and improving structure, it can be used normally, but the productivity is very low, the stroke of the mechanical press is fixed, easy to process, and automated, the future die forging process will improve the inherent quality of the die forging.
Due to the existence of white stripe defects at the fracture of die forgings, which are characterized by turbulence and small cracks, which are caused by weak points in the strong deformation area of the heart, in order to eliminate cracks in the core of die forgings, the heating temperature of the ingot must be controlled. , and the deformation of the die forging must be properly distributed twice, the ultra-high-strength aluminum alloy punching is a key component for the machine to withstand high stress during operation.
