Description

AC bead processing equipment

This creation relates to a bead processing equipment, and more particularly to an AC bead processing equipment.

The bead processor uses the electrochemical field to treat the surface oxide of the stainless steel through electrolytic reduction to achieve the reduction effect. The machine itself needs a DC power supply unit and two electrodes, one for the negative pole (cathode) and one for the positive pole (anode); the positive pole is the grounding wire, and the negative pole is electrically connected to the handle of the bead processor; when in use, the positive electrode ( The grounding wire is clamped on the workpiece, and the handle electrode part of the negative electrode is wrapped with an insulating cloth (the insulating cloth has an insulating water absorption effect). After the electrolyte is taken up; after the power is applied, the surface of the stainless steel is repeatedly scrubbed; the insulation of the electrode is wrapped by the handle portion. The electrolyte in the cloth is subjected to electrolytic chemistry to dissolve the oxide on the surface of the stainless steel to remove the weld spot.

However, the known bead processing processes require special equipment to achieve, so the cost of use is quite high; in addition, the handle portion of the bead processor on the market is mainly made of plastic tubes, soldering irons, and dials. The switch is composed of a moving iron head as an electrode. In the process of use, the soldering iron tip (electrode part) needs to be wrapped with a polishing cloth (having characteristics of insulation, water absorption, high temperature resistance, etc.), and the polishing cloth is often broken after high temperature, and the positive electrode and the positive electrode are The negative electrode will cause a short circuit, which not only causes surface damage of the stainless steel sheet (workpiece) after short circuit, but also requires repeated replacement of the abrasive cloth, resulting in a decrease in work efficiency.

However, the voltage outputted by the conventional bead surface treatment machine may be a single voltage or a multi-segment voltage, and a single voltage can only be applied to a bead surface of a single characteristic, such as a single thickness and a number of bead surfaces; The multi-segment voltage can be applied to the bead surface of different characteristics, such as various thickness and number of bead surfaces, and the voltage is coarsely adjusted through the switch, for example, the voltage is worth to be adjusted at 12 volts and 24 volts, but cannot be based on Used The actual weld bead surface of the workpiece is finely adjusted for output voltage and output power; and the positive electrode and the negative electrode are not reversed, otherwise the effect of the bead surface treatment cannot be achieved, and the risk of short-circuit fire may be caused.

Please refer to the Chinese mainland patent CN201120502901. After the bead processing device disclosed by the adjustable current flow device is adjusted, the bead treatment gun can be directly connected to the bead processing machine, and the electric welding machine (such as a DC argon arc welding machine) The DC device itself is used as a power source, and a current limiting device is installed at the output end of the welding machine to control the current through the current limiting device; however, the current at the output end of the welding machine cannot be rectified and the voltage waveform is adjusted. For square waves, to adapt to bead processing.

In addition, the bead processor is used in the field of electrochemistry, and the surface oxide of stainless steel is treated by electrolytic reduction to achieve the effect of reduction. The machine itself needs a DC power supply unit and two electrodes, one for the negative pole (cathode) and one for the positive pole (anode); the positive pole is the grounding wire, and the negative pole is electrically connected to the handle of the bead processor; when in use, the positive electrode ( The grounding wire is clamped on the workpiece, and the handle electrode part of the negative electrode is wrapped with an insulating cloth (the insulating cloth has an insulating water absorption effect).
