Embodiment Construction

[0004] The main chassis 1 is installed on the main chassis foot 101, and each of the two ends of the main chassis 1 has a symmetrical box A, and the middle part of the main chassis 1 has two symmetrical boxes B, and the two symmetrical boxes B share one The table top C and the top surface of the two symmetrical boxes A are equipped with a guide rail 2. The guide rail 2 is used for the movement of the left welding assembly 3 and the right welding assembly 4 in the rails, and pushes the cylinder 7 to connect with the left welding assembly 3 and the right welding assembly 4. The left welding assembly 3 and the right welding assembly 4 are driven by the push cylinder 7 to move forward or backward in the guide rail 2. Five welding cylinders 5 are respectively installed on the vertical surfaces opposite the left welding assembly 3 and the right welding assembly 4. The welding cylinders 5 can be used for front and rear horizontal telescopic movement, and the welding cylinder 5 can be ...

Abstract

The invention relates to an intermediate frequency inverter automatic welding machine special for a smoke exhauster hood. A plurality of welding spots can be automatically welded by one-time pressurizing; the whole machine adopts a single chip microcomputer to control each action; and an operation panel adopts a circular button switch which is intuitive and convenient to adjust. According to the intermediate frequency inverter automatic welding machine special for the smoke exhauster hood, the intermediate frequency inverter welding machine is adopted to convert an IGBT alternating current toa direct current, a resistance welding power source provides energy for welding, before welding, the welding machine absorbs energy from a power grid to charge a capacitor with a small current for a long time and store electricity, in the welding process, power supply of the power grid is stopped, thus current impact on the power grid like a power-frequency resistance welding machine is avoided, therefore, the requirement for the power supply capacity of the power grid can be reduced, in the welding process, discharge is rapid, the waveform is steep, the energy is concentrated, no alternatingcurrent zero crossing intermittent process exists, the welding thermal efficiency is high, adjustment and control are easy, thus structures with physical properties or thickness ratios which have great difference can be welded.

Description

technical field [0001] The invention relates to the technical field of automatic welding processing equipment, in particular to a special machine for automatic welding of intermediate frequency inverter hoods. Background technique [0002] The existing welding technology has been very common, and the existing technology generally has low efficiency, limitations, and unstable welding effect. It cannot be applied to multiple product specifications and simultaneous welding of multiple solder joints, and the physical properties or thickness ratio of welding are very different. structure is very difficult. The present invention aims at the deficiencies of the prior art, and can automatically weld multiple solder joints with one pressurization. The welding machine absorbs energy from the power grid before welding, and charges and stores the capacitor with a small current and a long time; the power grid is stopped during the welding process. Power supply avoids the current impact ...
