Forming Method of Titanium Alloy Door Hinge Forgings

Abstract

The invention relates to the field of forging technology, and provides a forming method for a titanium alloy door hinge forging, including: a design step of the door hinge forging and a parting step; Slopes and transitions. On this basis, the premise of determining the parting surface is to place the rear end surface of the side plate horizontally, and on this basis, determine the parting surface based on the maximum profile of the orthographic projection of the door hinge forging on the horizontal plane and the transition surface of the remaining forging block. The cavity depth of the side plate in the corresponding forging die is greatly reduced, which is more convenient for product filling and reduces defects during die forging. In addition, in the design of the door hinge forgings, it is possible to realize the design of no margin on the left side of the side plate and at the same time realize the design of the draft slope with a small margin on the right side of the side plate, so as to solve the problem of reverse draft on the right side of the traditional door hinge forgings , thereby saving materials and reducing manufacturing costs.

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 and 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 mater...
