The choice of forging equipment is mainly based on the technical requirements of forgings (such as projection area, thickness (height), shape, complexity and accuracy, etc.) and material characteristics, as well as the status of existing forging equipment in the enterprise. The main choice are forging hammer, electric screw forging press, hydraulic press.
1,Choose according to the characteristics of forging materials
All kinds of common forging press equipment can meet the requirements of common structural steel forgings. However, for special alloy forgings, the plasticity of materials and the requirements on the structure and properties of forgings have become an important basis for equipment selection.
The preferred forging equipment for aluminum alloy, magnesium alloy and copper alloy forgings is hydraulic press (especially large die forgings). For small and medium-sized aluminum alloy die forging, in addition to the hydraulic press, often choose screw forging press and mechanical press .
Titanium alloy forging is recommended to choose hydraulic machine die forging large titanium alloy die forging. Medium and small titanium alloy die forgings are made by mechanical press and screw forging press. In the absence of the above equipment, may choose the forging hammer.
The forging of stainless steel forgings is generally not limited by the type of forging equipment.
Large high-temperature alloy die forgings, such as turbine disc, are recommended to be forged by hydraulic press. Die forgings of medium and small high temperature alloy are recommended to be forged by screw forging press.
2,According to the forging projection area
High temperature alloy, titanium alloy and aluminum alloy large die forging, it is recommended to choose the hydraulic machine die forging. Structural steel and stainless steel large die forging, due to economic reasons generally choose to hammer and die forging hammer die forging; For extra-large structural steel and stainless steel die forging, it is recommended to choose hydraulic machine die forging.
High temperature alloy, titanium alloy and aluminum alloy medium and small die forgings, mechanical press and screw press die forgings are recommended. Small and medium-sized die forgings of titanium alloy can be made by forging hammer, mechanical press or screw forging press.
3,Select according to forging thickness (or blank height)
Hydraulic press is suitable for forging process with long working stroke of various materials.Die forging hammer and screw forging press are suitable for die forging thin forging, mechanical forging press and screw forging press are suitable for die forging high temperature alloy, titanium alloy, stainless steel, aluminum alloy, magnesium alloy and copper alloy forging.
4，Select according to forging precision
Mechanical forging press and spiral forging press are suitable for precision die forging of titanium alloy and stainless steel blades, aluminum alloy, magnesium alloy, copper alloy and other small and medium-sized forgings.Hydraulic presses and hammers are suitable for general die forging with general precision.
5，Select according to batch and economy of forging
Mechanical forging press is most suitable for automobile, agricultural machinery, medical equipment and other parts of large volume die forging production.Forging hammer and screw forging press are suitable for medium batch forging.Hydraulic press is suitable for small batch large die forging production.
