Capacitance energy accumulation type fusing soldering welder

Abstract

A capacitor energy storage nailing machine is disclosed. The charge branch of the nailing machine includes a charge part (25), a transformer (21), a rectifier bridge (23) and an energy storage capacitor (24), which are linked in tandem. A discharge branch includes the energy storage capacitor and a discharge thyristor (27). The charge and discharge branches are connected with a charge / discharge controller (26), which is connected with a trigger switch. The braches of the present capacitor energy storage nailing machine such as charge, discharge, triggering, over voltage protection and charge indication, etc. are respectively controlled by a plurality of output terminals of the charge / discharge controller which are output and scanned by a sequence pulse subterminal which is independently triggered by the trigger switch, thereby separating the strong and weak electricity thoroughly and completely. The present nailing machine can perfectly protect the circuit, can avoid the serious consequences caused by the simultaneous charging and discharging because of a disturbance, can solve the disadvantages that valuable circuit elements of the prior product such as the transformer, the charge thyristor, the relay and the circuit board are easily damaged, and can eliminate hidden dangers caused by the bad insulation of a conductor.

Description

technical field [0001] The utility model relates to a capacitor energy storage type welding machine (nailing machine), in particular to a control circuit for controlling the capacitor energy storage type fusion welding machine. Background technique [0002] At present, the shipbuilding fusion welding machines that have been put into use such as figure 1 shown. Wherein, the control circuit of this type of capacitive energy storage type fusion welding machine in the prior art is electrically connected with the charging thyristor 3, the rectifier bridge 2, the transformer 1, the energy storage capacitor 7, and the discharging thyristor 8 in sequence by the grounding detection 5 constitute. The fusion welding machine relies on the grounding detection 5 to detect whether the gun head 0 is lifted or dropped, so as to control the charging and discharging, that is, it will be charged when it is lifted, and it will be released when it is dropped, and it is directly manually trigger...
