Abstract

The invention provides a pin tube automatic set submerged arc welding set which is characterized by comprising a pin automatic loading-unloading system, a welding system, an automatic pin delivering and centering mechanism and a programmable logic controller (PLC), wherein the PLC is connected with the automatic loading-unloading system, the welding system and the automatic pin delivering and centering mechanism; the functions of automatic nail feeding under air pressure, hydraulic centering, and automatic sending of fixed quantity of welding flux and the like are realized through using the welding set; in the control system, the PLC is mainly used as the main control device matched with a full-digital AC servo driver, so that the pin tube welding set can be used to realize accurate and effective full-automatic control in the welding process; and the welding set is suitable for automatic welding of large-diameter pins and large-diameter light tubes in shapes of cylinder, droplet and rhomboid, and overcomes the defects of arc pits, welding beading, bubbles and the like, the production efficiency is enhanced and the labor intensity is lowered. The invention has simple structure and is easy to manufacture.

Description

[0001] Technical field: The present invention relates to a submerged arc welding processing equipment based on PLC technology and servo control technology, in particular to an automatic complete set of submerged arc welding equipment for nailhead tubes, which belongs to the field of welding automation technology. Background technique: [0002] The nail head tube is the main element of the heat exchanger widely used in petrochemical machinery. It is composed of a steel pipe and nail heads densely covered on the surface. At present, the welding methods used for nailhead pipe mainly include resistance welding, arc stud welding and submerged arc welding. For example, patents 94228692.8 and 99253080.6 all adopt the resistance welding method; if there are literature reports, the nailhead tube automatic welding machine adopts short-cycle arc stud welding, and the nailhead tube automatic capacitor energy storage high-efficiency energy-saving welding machine adopts arc stud welding. Na...
