[CN 201720906239.4] Pneumatic air hammer


[CN 201720906239.4] Title of a Pneumatic Air Hammer: Application Number of a Pneumatic Air Hammer: CN 201720906239.4 Applicant: Application Date of Libo Heavy Industry Technology Co., Ltd.: 2017-7-25 Patent Type: Utility Model The utility model relates to a pneumatic air hammer including a base, a stressed seat, a limit block, a fan-shaped hammer, a compression cylinder, a support frame, a pull-back spring, an electromagnetic valve and a foot switch, the fan-shaped hammer can move freely within a certain range to meet its running route; the fan-shaped hammer and the base are connected by the pin shaft, which can ensure that the fan-shaped hammer moves around the pin shaft. The utility model uses the pneumatic power and lever principle plus the impulse generated by the weight of the fan-shaped hammer, and then effectively flattens the round tube, reduces the cost and operating resistance, and increases the economic benefit; the cylinder push, the lever principle and the fan-shaped hammer's own impulse are used Effectively improve the work efficiency per unit time.
