Process Conditions of Die Forgings

Process conditions of die forgings
At present, it is understood that in the application process of die forgings, it mainly refers to the parts with die forgings. During operation, the precision of die forgings is relatively high and the die forgings are complex. For free die forgings, the punching characteristics should be better. Free die forgings basically have no molds, only forging shafts, rings and other extremely simple things, while die forgings can die forging many products, and can control the dimensional tolerance of products and reduce the amount of processing.
Influence of the die forging process on the fiber direction of the die forging, the position of the mechanical property test strip, the printing position, the steel grade, etc., the qualified quality die forging must also meet the following requirements: According to the die forging procedure, all dimensions must be Comply with the dimensions of the drawing die forgings, and at the same time, must comply with the drawing die forgings, the technical requirements specified above.
1. The forging press has an ejector device, which can be used for die forgings with long rods, that is, the axis of the rod is consistent with the moving direction of the slider, so as to reduce the perimeter of the separation surface matrix die forgings and reduce the metal content in strawberries, consumption quantity.
2. For the die forgings of the die forging machine, the average size of the rest of the die forgings is 30-50% smaller than that of the hammer, and the specific numbers can be found in the corresponding manuals.
3. If the pliers take out the die forging from the cavity, the slope of the die forging is determined as the hammer die forging, when the ejector is used to push the die forging, the die forging can be significantly reduced, but not completely absent, otherwise the jack will be overloaded.
4. The dies used for die forgings are called die forgings. From the beginning to the final formation of metal deformation, the corresponding matrix of the die forging base is used. Through the action of the dovetail tenon and the keyway, the die forging base can be prevented from falling out. It is fixed on the dovetail of the hammer by the key block and the iron wedge. The deflection directions of the upper and lower molds are different. The small head of the key block is in the keyway of the die forging, and the large head is in the dovetail groove of the keyway. The hammer head or the mold base.
