[CN 201721666684.4] Hammer head of a shaft four-anvil diameter forging machine Title: Hammer head of a shaft four-anvil diameter forging machine Application number: CN 201721666684.4 Applicant: Jiangsu Standard New Industry Co., Ltd. Application date: 2017-12-5 Patent type: Utility model A shaft four-anvil diameter forging machine hammer head, including shaft forging blank, the four directions of the shaft forging blank are evenly distributed with four forging machine hammers, characterized: the hammer head of the forging machine is set as a cuboid with a composite surface on one side, the composite surface includes a contact surface and a preformed combined surface with a preformed surface, the contact surface consists of two integral sections and two ends of the shaping section connected The forming section forms a trapezoid with high middle and low ends, the shaping section is higher than the preformed section, and the surfaces of the shaping section and the preformed section are provided with concave arc surfaces; the shaft forging blank uses an eight-node hexahedral unit to divide the 2Cr13 material. The utility model designs the contact surface as a composite surface combining the arc surface and the pre-formed surface, which can reduce the forging pressure while improving the quality of the forging core, reduce the tonnage requirement of the equipment, and reduce the loss of the machine.
