[CN 201910731356.5] Gear drive type hammering structure for forging machine
[CN 201910731356.5] A Gear Transmission Hammering Structure for Line Forging Machine Title: A Gear Transmission Hammering Structure for Line Forging Machine Application Number: CN 201910731356.5 Applicant: Shaoxing Shangyu Jiesheng Copper Co., Ltd. Application Date: 2019-8-8 Patent Type: Invention Application The present invention discloses a gear transmission hammering structure for line forging machine, it includes a rotating outer ring, a hollow mandrel, a hammer head, a cage, and a plurality of cylindrical needle rollers mounted on the cage. One end of the rotating outer ring is provided with an inner ring gear, and one end of the hollow mandrel is provided with an outer ring gear. One end of the two or more cylindrical needle rollers is provided with planetary gears matching the inner ring gear and the outer ring gear, the hammer head is telescopically connected to the hammer punch, and each time the cylindrical roller needle is held against the hammer head, the hammer head extends into the hollow core shaft to hammer the workpiece once. The invention adopts the structure of the inner ring gear and the planetary gear to realize the rotation of the outer ring to drive the rotation of the cylindrical needle roller and the cage, which not only ensures the smooth and reliable rotation of the cylindrical needle roller and the cage, ensures the hammer effect, but also reduces the inner wall of the rotating outer ring and the cylinder The wear between the rollers extends the service life.
