[CN 202210459293.4] air hammer structure for flange plate forging
[CN 202210459293.4] Title of Air Hammer Structure for Flange Forging: Application Number of Air Hammer Structure for Flange Forging: CN 202210459293.4 Applicant: Jiangsu Ya Gu Standard Parts Co., Ltd. Application Date: 2022-4-28 Patent Type: Application of the Invention The present invention relates to the technical field of forging, and discloses an air hammer structure for flange forging, including an air hammer body, the two sides of the inner cavity of the air hammer are divided into two chambers, in addition, a working piston is movably connected to one side chamber of the air hammer body, and a connecting pipe communicating with the atmosphere is connected to the lower chamber of the working piston inside the air hammer body, and a compression piston is movably connected to the other side chamber of the air hammer body. Through the setting of the fixed pipeline, the fixed pipeline is connected with the upper part of the working piston and between the fixed sleeve and the outer sleeve. When the compression piston is connected with the upper part of the working piston by rotating the upper rotary valve, the compressed gas above the compression piston is filled into the inner side of the fixed sleeve and the outer sleeve through the fixed pipeline, so that the anvil is affected by the compressed gas and the working piston moves synchronously, the bottom end of the working piston and the top end of the anvil are hedged, which improves the effect of forging, and reduces the impact vibration of forging through the hedging effect of air pressure.
