Electric welding pliers with good heat dissipation function

Abstract

The invention discloses an electric welding tongs with good heat dissipation function, which comprises a main body of electric welding tongs and a conductive connector. A hand-held arm is fixedly installed on the upper end of the main body of the electric welding tongs, and an insulating protective leather sheath is arranged on the outer edge of the hand-held arm. The lower end of the main body of the electric welding tongs is hinged with a lever curved arm through a rotating shaft. It is connected with the holding arm through a support, the inner cavity of the support is equipped with a spring, the conductive connector is fixedly installed in the inner cavity of the main body of the electric welding tongs, one end of the conductive connector is connected to the upper clamping jaw, The other end of the conductive connector is provided with a wire hole, and the conductive connector includes a copper straight handle and a copper insert, and the copper straight handle and the copper insert are connected to each other through threads. The electric welding tongs with good heat dissipation function are safe and convenient to use, improve work efficiency, and have a long service life and significantly improved.

Description

technical field [0001] The invention relates to the technical field of electric welding equipment, in particular to an electric welding clamp with good heat dissipation function. Background technique [0002] At present, natural cooling welding pliers are commonly used in my country. The welding pliers work under low voltage and high current conditions. The existing electric welding pliers are electrically connected internally, and the resistance is large, which makes the contact point oxidized and heats up more easily. The welding pliers are long Time work itself will generate a lot of heat. The welding pliers will also generate strong heat during welding, thereby increasing the overall temperature of the welding pliers, making them hot and forced to stop working. The high temperature will age the insulating glue of the welding pliers. Loose and deformed, due to the defects of the welding tongs themselves, generally the welding tongs are used for a long time, the handle will ...

[0002] At present, natural cooling welding pliers are commonly used in my country. The welding pliers work under low voltage and high current conditions. The existing electric welding pliers are electrically connected internally, and the resistance is large, which makes the contact point oxidized and heats up more easily. The welding pliers are long Time work itself will generate a lot of heat. The welding pliers will also generate strong heat during welding, thereby increasing the overall temperature of the welding pliers, making them hot and forced to stop working. The high temperature will age the insulating glue of the welding pliers. Loose and deformed, due to the defects of the welding tongs themselves, the handle will be hot when the welding tongs are used for a long time, so they cannot work for a long time, and the life of the welding tongs is also very short

[0003] When electric welding is working, toxic gas will be produced, which is easy to inhale into the lungs, and cause human body to be violated. The existing equipment cannot solve it well.
