无轨式锻造操作机 技术领域 Trackless forging manipulator TECHNICAL FIELD
本实用新型涉及一种锻造机械, 特别是一种无轨式锻造操作机。 背景技术 The utility model relates to a forging machine, in particular to a trackless forging manipulator. Background technique
现有的锻造操作机, 一般都具有大车行走底盘, 工作台架和钳杆机构三 个部分, 这种锻造操作机的钳杆机构不能作前后移动, 而锻件在砧座上需要 频繁地进行前后移动, 只能由锻造操作机整件作前后运动来完成, 由于锻造 操作机的质量比较大, 因此需要配置较大功率的电机, 消耗功率大, 同时, 由于其质量大, 运动时的惯性较大, 相应地其运动速度较慢, 造成锻造操作 机的工作节奏缓慢, 这对于趁热打铁的锻造来说是个重大的缺点, 另外, 锻 造操作机的钳杆不能随锻件的高度变化自动作上下倾斜运动, 锻造操作机在 对圆饼、 方块和长轴类锻件进行锻造时, 需要锻件在砧座上不断地转动, 但 现有锻造操作机不能完成这种动作。 发明概述 Existing forging manipulators generally have three parts: a cart chassis, a workbench and a jaw mechanism. The jaw mechanism of this forging manipulator cannot be moved back and forth, and the forgings need to be frequently performed on the anvil. The back and forth movement can only be completed by the forging manipulator as a whole. Because the mass of the forging manipulator is relatively large, it needs to be equipped with a higher power motor, which consumes large power. At the same time, due to its large mass and inertia during movement Larger, correspondingly, its movement speed is slower, resulting in a slow working rhythm of the forging manipulator. This is a major disadvantage for forging while the iron is hot. In addition, the tong bar of the forging manipulator cannot automatically tilt up and down with the height of the forging. Movement, forging manipulators need to continuously rotate the forgings on the anvil when forging wafers, cubes and long shaft forgings, but the existing forging manipulators cannot complete this action.
