Forming method of titanium alloy vehicle door hinge forge piece

Abstract

The invention relates to the technical field of forging, and provides a forming method of a titanium alloy vehicle door hinge forge piece. The forming method comprises a vehicle door hinge forge piecedesign step and a parting step, wherein the vehicle door hinge forge piece design step is used for designing a forging residual block for the vehicle door hinge forge piece, and the forging residualblock comprises a pattern drawing bevel and a transitional surface. On the basis, a parting surface is determined on the premise that a rear end face of a side plate part is transversely placed, and the parting surface is determined on the basis of the maximum orthographic projection outline of the vehicle door hinge forging on a horizontal plane and the transition surface of the forging residualblock, so that the cavity depth of the side plate part corresponding to the forging die is greatly reduced, mold filling of a product is further facilitated and defects during die forging are reduced.Besides, when the vehicle door hinge forge piece is designed, a small allowance draft angle on the right side of a side plate part is designed while a design on the left side of the side plate part without allowance is achieved, and a problem of drawing a pattern reversely on the right side in a conventional vehicle door hinge forge piece is solved, so that materials are saved and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forming method of a titanium alloy door hinge forging. Background technique [0002] figure 1 with figure 2 The door hinge shown in is applied to an off-road vehicle, including the floor 01 and the side rib 02, which are specifically used for the external connection of the door and the body to realize the opening and closing of the door. Since such door hinges currently on the market are made of steel materials, although their manufacturing cost is low, in complex environments such as wilderness, mountains, swamps, deserts, and ice and snow, steel materials are prone to failure due to large climate changes. In case of corrosion, rust or even damage, the cost of later maintenance and replacement will be high. [0003] In view of the above-mentioned problems existing when the existing car door hinges are made of steel materials, there is an urgent need for an alternative mate...
