Accurate prediction of the dimensional accuracy of calcined parts, is the spiral bevel gear cold forgings scientific research problem, clearly put forward the way to predict the dimensional accuracy of cold forgings. Precision casting manufacturer according to finite element analysis simulation calculation, predicted the size accuracy of spiral bevel gear cold forgings, precision casting aluminum alloy grasp to wetting the standard to cold forging parts size accuracy of the hazard, based on practical experience proved that the way is simple and easy, can reasonably assess the size accuracy of spiral bevel gear cold forgings.

When setting other standards, the lower the dimensional accuracy of the square billet, the current stage of casting die cold forgings, the lower die precision positioning sleeve set in the fixed immovable guide ring, can be in the fixed immovable guide ring inner cavity efficacy, in the upper die precision positioning sleeve and mobile upper cavity middle, movable die and upper die is the radial buried hole coaxially adjustable, and mobile lower die is coupled to the fixed immovable guide ring, with the fixed immovable guide ring is The top frame of the rectangular frame of the top frame and the guiding sleeve specification of the rectangular frame are placed on the positioning pins, and the precision casting parts processing can be moved around along the positioning pins under the action of external force, and the steel cutting is located in the lower side of the upper die and the lower rod vertically penetrating into the steel cutting in the lower cavity.

At this stage choose nowadays cold forging parts forming technicality, reduce the difficulty factor of laser cutting small and medium-sized nowadays, production and manufacturing high efficiency, raw material use high efficiency, low production cost, wear-resisting performance is good, level transmission system drive gear journal, nowadays use to segment figure water-cooled heat dissipation part of the dovetail guide notch of the tower wheel set with wheel body and shaft over the hole axis, and the behavior of the body of the wheel is equipped with The correct guide groove, the correct guide to move the construction steel, now the current favorable practical effect of the construction of easy, increased the use of machinery and equipment period.
