摘　　要：模具喷涂石墨脱模剂润滑在锻造生产过程中起着关键作用,在多工位数控螺旋压力机自动化生产线中,人工喷涂石墨脱模剂的方式往往会造成喷涂不均匀、喷涂效果差,影响工件脱模,降低生产效率,使锻造自动化生产线运行不畅。结合锻造工艺,设计了一种数控螺旋压力机用多工位自动喷墨装置,由石墨供给和石墨喷涂两部分组成,利用气压传动和PLC控制技术对其进行传动与控制。对该装置进行调试验证并对石墨喷涂部件中的主要受力件万向轮滚轮架进行有限元分析。验证结果证明,该装置能够实现喷墨量与喷墨位置可控,喷墨均匀一致,且结构简单、成本低,可在多工位数控螺旋压力机自动化生产线上进行推广。The lubrication of mold spraying graphite demoulding agent plays a key role in the forging production process. In the automatic production line of multi-station CNC screw press, the mode of manual spraying graphite demoulding agent often results in uneven spraying and poor spraying effect, which affects the demoulding of workpiece and reduces production efficiency, and makes the automatic production line of forging run poorly. Therefore, combined with the forging process, a multi-station automatic ink-jet device for CNC screw press was designed, which was composed of graphite supply and graphite spraying. Then, the device was driven and controlled by pneumatic transmission and PLC control technology. Furthermore, the device was debugged and verified, and the finite element analysis of universal wheel roller frame in the graphite spraying components was conducted. The experimental results show that the device can realize the controllable quantity and position of ink-jet, uniform ink-jet, simple structure and low cost, and can be popularized in the automatic production line of multi-station CNC screw press.
