工业点焊机的设计 摘 要 点焊机又称电阻焊机，是利用被焊工件的自身的电阻，在局部通过大电流产生高温而使工件熔接起来的焊接设备。由于热量来源于工件的内部，因此电阻焊机有着广泛的运用。我国电阻焊技术经历了工频交流、直流脉冲、三相低频、次极整流、微机控制和质量监控技术水平的提升过程。目前，我国采用微机控制的次极整流的点/缝焊机、带恒流输出的质量控制电阻焊机的应用已较为普遍，电阻焊质量控制理论和技术、各种通用及专用电阻点/缝焊机、成套设备的研究和应用已较为普遍和成熟，接近国际先进水平。电阻焊Industrial spot welding machine Abstract Also known as resistance spot welding machine, welder was using pieces of their own resistance, in the local heat generated through the high-current welding of workpieces up welding equipment. As a result of internal heat from the workpiece, so have a wide range of resistance welding machine to use. Resistance welding technology in China has experienced the exchange frequency, DC pulse, three-phase low-frequency, secondary rectification, microprocessor control and quality control of the process technology level. At present, the use of microcomputer-controlled secondary rectification point / sewing machine, with constant current output of the quality control of the application of resistance welding machine has been more widespread, resistance welding quality control theory and technology, a variety of general and resistance spot welding machine dedicated / professional resistance seam welding machine slit welder, complete sets of equipment for research and applications are more common and mature, close to international advanced level.  The main requirement of the task to design a spot welder for industrial use. Such a spot welding machine used in the main workshop, conducted on the spot welding parts, welding parts to complete fixed. Such equipment can completely replace the existing manual operation, greatly improving the productivity of machining.
