对击锤是生产中型和重型模锻件必不可少的设备。为提高锻件精度而进行的结构上的改革,促使机架日益得到改进。对击锤新式机架是箱形双柱式结构。机架的重要条件之一是要具备静力刚度与动力刚度。为了降低锻造时因动力作用引起的机架变形并增大刚性,可以采用肋板。提高动力刚度和减振作用的目的是:使立柱本身的质量以及附加的质量(缓冲材料,基础块体等)能够准确地固定。结构良好的机架应能在功能、设计和制造各方面达到下列要求:锤头能稳定地导向;导轨易于精确调节;具备静、动力刚度;在锻造时出现的力可在允许变形的条件下予以吸收,通过减振可减少和吸收对机器与环境有害的震动;能保护锻锤的易损件(钢
The hammer is an indispensable device for the production of medium and heavy die forgings. Structural changes to improve the precision of forgings have led to an ever-improving rack. Hammer new rack is a box-shaped double column structure. One of the important conditions of the rack is to have static stiffness and dynamic stiffness. In order to reduce the forging deformation caused by the dynamic effect of the rack and increase rigidity, you can use the ribs. The purpose of increasing dynamic stiffness and damping is to enable the column itself to be precisely fixed in terms of quality and additional mass (cushioning material, foundation block, etc.). A well-constructed frame should meet the following requirements in terms of function, design and manufacture: The hammer head can be stably guided; The guide rail is easy to adjust precisely; Static and dynamic stiffness; The force that occurs during forging can be applied under permissible deformation To be absorbed through the vibration reduction can reduce and absorb the vibration of the machine and the environment; to protect the hammer wearing parts (steel
