Anti-scalding electric welding pliers

Abstract

The invention discloses anti-scalding electric welding pliers which comprise an upper plier nozzle (1), an upper handle (2), a return spring (3), a connecting frame (4), a handle (5) and a conductor (6). A connecting nozzle insulation heat-insulating block (7) is arranged between the conductor (6) and the handle (5). A lower plier nozzle (7.1) is formed at the front end of the connecting nozzle insulation heat-insulating block (7). The connecting nozzle insulation heat-insulating block (7) is hinged with the upper handle (2). The conductor can be isolated to transfer heat to the handle. The anti-scalding electric welding pliers have more excellent safety performance. The invention belongs to the technical field of welding equipment.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to an anti-scald electric welding tongs. Background technique [0002] Existing electric welding pliers are mainly composed of pliers mouth, upper handle, spring, connecting frame, insulating handle and conductor installed in the insulating handle; An arc is generated between the electrode and the body to be welded to melt the electrode to achieve welding. The electric conductor on the existing electric welding tongs is basically made of copper material, the rear end of the electric conductor is used to connect and fix the power line, and the front end of the electric conductor becomes the lower jaw of the electric welding tongs. Both sides of the front end of the conductor are bent down to form two folds, so that the front end of the conductor becomes a U-shaped groove, and the two folds bent down touch the inner wall of the insulating handle, and the conduct...

AI Technical Summary

Problems solved by technology

[0003] The welding pliers of the above structure have the following disadvantages: 1. The two folded edges of the conductor are in direct contact with the insulating handle. The heat generated by the current of the conductor itself will be transferred to the insulated handle through the two folded edges of the conductor and the screws connecting the conductor and the insulated handle, so that the surface temperature of the insulated handle can reach more than 40 degrees, and the operator will easily feel very hot , so that the operator has to stop and continue welding after the handle cools down, which affects the work progress

2. The conductor is fixed on the handle by a screw, and the stem of the screw is directly screwed on the conductor. Since the conductor is electrified when the welding tongs are working, the screw is also electrified, and the screw head is exposed in the screw hole of the insulated handle. There are safety hazards, the operator's fingers are easy to touch the screw head exposed in the screw hole, and an electric shock accident occurs

[0004] To sum up, at present, the hot handle of welding tongs is the main reason why operators cannot use welding tongs for a long time; the screw on the handle is live, which is the cause of electric shock accidents
