Background technology
At present, it is to adopt electric iron to weld that the inner and outer conductor of domestic radio-frequency cable assembly welding is welded with a part with binding post, but there is inconvenient operation in it and causes characteristics such as rosin joint because of local heat easily; Another part is to adopt the welding of copper electrode resistance welding machine, and resistance welding machine has well solved the rosin joint phenomenon that is caused by the local heat of weldering body, but the electrodes use copper alloy electrode of most domestic resistance welding machine; But the easy oxidation when welding of its surface after multiple welding, must polish off the end face oxide layer; If detail sanding is bad; Because the oxidation of end face or dirty is easy to generate electric spark when welding at electrode and between by the weldering body, and will be by weldering surface corrosion of coating; There is oxidation stain clearly, thereby influences product appearance and performance.During welding, if electrode itself produces heat when big, copper electrode and can being produced between the weldering body bonds.
Summary of the invention
What the present invention proposed is resistance welding machine graphite electrode structure and installation method; Its purpose is intended to overcome the above-mentioned defective of existing in prior technology; The resistance welded machine electrode is bonding through adhesive through the graphite powder that adds silver powder; Be cast into piece, will become the machining graphite of piece to become the graphite electrode of respective shapes then; Through electrode compressing tablet and screw are fixing electrode is installed on the sectional fixture; Sectional fixture is respectively installed on high-frequency welding machine base and the movable pulley; The both positive and negative polarity sectional fixture is through the insulation of polytetrafluoroethylene (PTFE) epoxy plate; Anodal sectional fixture is through conductive copper sheet and positive source conducting.
Technical solution of the present invention: resistance welding machine graphite electrode; It is characterized in that comprising the sectional fixture, conductive copper sheet, movable pulley, insulating pad of graphite electrode, electrode compressing tablet, mounting screw, negative pole, anodal sectional fixture, high-frequency welding machine base; Wherein graphite electrode is installed on the sectional fixture of negative pole through electrode compressing tablet and mounting screw; The sectional fixture of negative pole is installed on the bonding machine pedestal; The sectional fixture of negative pole joins through the power cathode of insulating pad on the bonding machine pedestal and resistance welding machine, and anodal sectional fixture joins through the positive source of conductive copper sheet and resistance welding machine, is insulating pad between anodal sectional fixture, the sectional fixture of negative pole and high-frequency welding machine base; On the anodal sectional fixture movable pulley is installed, but anodal sectional fixture is through the movable pulley move left and right.
The installation method of resistance welding machine graphite electrode comprises following processing step:
One, processing graphite electrode mixes the graphite powder that adds silver powder through resinoid bond, be squeezed into piece, will become the machining graphite of piece to become the graphite electrode of respective shapes then; The shared percentage by weight of described graphite, silver powder and resinoid bond is respectively 10%, 85%, 5%;
Two, the graphite electrode that is processed into is fixed on respectively on the sectional fixture of negative pole, the anodal sectional fixture through electrode compressing tablet and mounting screw;
