Description
Technical field
The utility model belongs to technical field of welding equipment, particularly relates to a kind of electrode holders.
Background technology
Weld job is clearly decided to be job that requires special skills, because this operation has great harm for operator, other people, the safety devices of peripheral facilities, trigger, initiation fire and equipment scaling loss be all the most incidental casualties and property loss accident in weld job.With regard to electrode holders and welding cable, because it has ambulant handling characteristics, and be contact the most charged equipment with operating personnel in weld job, big current flows through from electrode holders handle, electric welder and the relevant personnel may contact these equipment and relevant charged object at any time, as changed welding rod, arrange weldment, move cable, the operant activity such as handling electrode holders, operating personnel will contact them directly or indirectly, also have unintentionally many or touch unexpectedly, undefended owing to being milli, so be also the most dangerous.
Electrode holders are clamping welding rods, conduct the apparatus of welding current during welding.Matching used with arc welder, during manual electric arc welding, in order to clamping and manipulating electrode, and the hand-held insulation utensil that guarantee and welding rod are electrically connected.Electrode holders have shell protection, anti-electric shock protection, temperature rise value, proper alignment to splash, the resistance to the key technical indexes such as to fall.Electrode holders generally make clip with casting copper, and pottery and plastic handle make insulator, good electric conductivity should be had, not easily generate heat, lightweight, clamping welding rod firmly and change the welding rod property such as conveniently.Electrode holders are main tool of SMAW, and its Main Function is clamping welding rod pass to electric current, and working condition and the life security of it and welder have very big relation.Require that electrode holders must possess good insulating properties and heat-insulating capability, finger protecting baffle plate should be had between gripper handles and jaw, the insulating elements such as soldering turret front cover shell, rear casing, curved boom shell and handle case must be complete, must not have cracked or defect phenomenon, the insulaion resistance between insulated part and conductive component should be greater than 1 Μ Ω.
Existing electrode holders generally comprise clamp, electric conductor and handle, electric conductor is generally fixed on clamp, handle is the cylindrical shell of hollow, be connected to the rear end of clamp, cable inserts forward from the rear end of handle and is fixedly connected with electric conductor, electrode holders clamp welding rod by jaw, electric conductor is to welding rod transmission current, welding rod and soldered body produce arc-melting welding rod and then are welded by the body needing to weld, electric conductor on existing electrode holders adopts copper material to make substantially, electric conductor rear end is for connecting wire, and the front end of electric conductor is as lower clamp nozzle.Because cable conductor is through the cavity of handle, operator operate time hold handle carry out welding operation time, electric current makes the temperature of handle raise, and break-off of having to makes it cool, and also easily makes the hand of operation be burned, or generation electric shock accidents.
Utility model content
