Precision forging mold capable of conducting automatic lateral pressing and vibration reducing and vibration reducing method for forging mold

Abstract

The invention relates to the technical field of precision forging, in particular to a precision forging mold capable of conducting automatic lateral pressing and vibration reducing and a vibration reducing method for the forging mold. An upper movable block (a lower movable block) is driven by a first oil cylinder (a second oil cylinder) to get away from an upper fixed block (a lower fixed block), an upper mold body (a lower mold body) can be put into an upper installing groove (a lower installing groove) of an upper mold base (a lower mold base) accordingly, then the first oil cylinder (the second oil cylinder) stops driving, the upper movable block (the lower movable block) presses the upper mold body (the lower mold body) under the effect of a compression spring, the upper mold body (the lower mold body) is fixed accordingly, and the upper mold body (the lower mold body) is quite convenient to replace. When forging is carried out, as one side of the upper mold body and one side of the lower mold body abut against the upper fixed block and the lower fixed block respectively, automatic positioning can be achieved, large instantaneous impact force is generated when forging is carried out, and the impact energy can cause mold vibration; and due to the effect of the compression spring, the horizontal direction impact energy is absorbed, the instantaneous impact force is reduced accordingly, automatic resetting is achieved, and the service life of the mold is prolonged.

Description

technical field [0001] The invention relates to the technical field of precision forging, in particular to a precision forging die capable of side automatic compression and vibration reduction and a vibration reduction method for the forging die. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. For larger components, such as automobile steering knuckles, the forging die needs to withstand a large instantaneous impact force during forging, and most of the impact force is absorbed by the die, resulting in easy damage to the forging die. There are two types of existing forging dies: the integral die and the insert die. The insert die is to make the upper die and the lower die into inserts, and the upper die and the lower die are installed on the upper die base and the lower die base respectively w...
