【摘要】 物料自动传输技术在冲压生产线等方面有巨大的需求,冲压加工广泛应用于汽车、航空、家电等工业领域,其加工过程就是对原材料进行冲压拉伸、折弯、裁剪制成产品或半成品,其加工方式是冲床驱动模具的凸模对送到凹模的材料进行冲压拉伸或折弯、裁剪加工,主要用于批量生产,如用人工操作加工,就具有劳动强度高和危险性高的特点,也无法充分发挥生产线的效率。铝—不锈钢复合底不锈钢锅是一种节能和提高加热均匀性的厨具新产品,铝—不锈钢复合底不锈钢锅在制造过程中需要将锅体加热并输送到压力机上进行不锈钢锅体、铝导热体以及不锈钢底板的焊接。高温物料的自动传送涉及传输速度与节能问题有其特殊性。本文针对铝—不锈钢复合底不锈钢锅体高温物料的自动传输系统,重点进行了不锈钢锅底生产流水线的自动上下料方案设计、生产流水线的PLC控制系统设计、上下料机械手结构及控制程序设计与开发。首先基于高温物料生产线的节能减耗优化设计,根据压力焊机的生产节拍优化设计高温物料生产线的配置,采用传送带快速传送工件到上料机械手附近,用机械手夹持工件快速移动。其次,高温物料的上下料机械手结构和控制过程优化,上料机械手的顺序动作均采用气缸加压力控制阀及行程开关实现,并用定位块配合压力控制阀来完成压焊机的工件定位要求；下料机械手用三轴数控运动实现,伸缩臂动作、升降臂动作、地面移动均使用伺服电机作动力源,转臂动作用旋转气缸加行程开关来实现,夹持工件动作用直线移动气缸加压力控制阀来实现。接着,根据高温物料传输系统所处的高温、高噪声环境进行系统稳定性和绝热性结构和控制方案设计,减少整个系统的控制环节。最后,采用PLC控制系统实现高温物料自动上下料系统的优化控制,提高流水线的柔性生产能力,实现上下料的各种动作,减少高温物料传输过程的热量耗散。更多还原

【Abstract】 Automatic transmission technology has a huge demand in the press production lines, and stamping is widely used in automotive, aerospace, electronics and other industries. Stamping processing is stretching, bending, cutting or semi-finished products for raw materials, and processing method is tensile or bending, cutting processing for punch driven die, is mainly used for mass production, such as the use of manual processing, which have high labor intensity and high-risk characteristics and can’t give full play to the efficiency of production lines. Aluminum-stainless steel clad bottom stainless steel pot is the new kitchen products which save energy and improve the heating uniformity, in the manufacturing process which requires to heat the pot, then to transfer to the press to weld the stainless steel pot, aluminum conductors and stainless steel floor. The automatic transfer of high-temperature materials has its particularity on energy issues and transmission speed.In this paper, it focuses on automatic loading and unloading design of a stainless steel pot production lines, PLC control system design of production line, structure of loading and unloading manipulator and control program design. Firstly, based on optimal design on saving energy and reducing consumption of high temperature material production line, it transfers the workpiece to the vicinity of the robouse by using conveyor, according to the configuration of high-temperature materials production line. Secondly, the order of the feeding robot movements is implemented by using pressure control valve and travel switch, and completed the requirements of the workpiece positioning by using the pressure control valve positioning block with pressure welder; Cutting machine hand is completed by using axis NC movement:telescopic movement, lifting arm moves, the ground are using the servo motor for mobile power source, a rotating cylinder arm movements is completed by using additional limit switch, and the workpiece moves is completed by using with a linear increase cylinder pressure control valve. Then, design stability, thermal insulation structure and control according to the high temperature and high noise environment in the material transfer system. Finally, it achieves optimal control of automatic loading and unloading system, improves the lines of flexible production capacity, completes a variety of actions and reduces the heat dissipation of the heat transfer material by using PLC control system.更多还原
