Embodiment Construction

[0029] The specific structure of the present invention will be described in detail according to Fig. 1-11. The wedge-type electric welding tongs includes a joystick assembly, a wiring assembly, a handle assembly and other components assembled together. Wherein the joystick assembly includes: iron backing plate 1, upper clamp head plate 2, joystick 3, pin shaft 4, tension spring 5, screw 6, seat cover 7, insulating seat cushion 8 and other parts. Wiring assembly comprises: lower jaw plate 11, lower support iron plate 12, bearing 13, screw 14, screw 15, pressure wire plate 17, fixed frame 18, wedge-shaped briquetting block 19, spring support iron plate 20 etc. parts. The handle assembly includes: an insulator 16, a support tube 23, a heat insulator 22, a reflective film 10, a handle cover 21, a heat insulation pad 9, a heat insulation ring 24 and the like.

[0030] The iron backing plate 1 in the joystick assembly is welded together with the iron skeleton of the joystick 3, and...

Abstract

A pair of wedge-type electrode holders efficiently solves the problems in the prior electrode holders, such as a scalding handle caused by the loose pressure of a cable conductor at a joint and so on. The invention includes a control rod assembly, a connection assembly and a handle assembly. The technical points are as follows: an upper tong head plate in the control rod assembly is fixed with a control rod via an iron backing plate, a lower tong head plate in the connection assembly is fixed with an insulator of the handle assembly via a lower supporting iron plate, the bevel ends of the lower tong head plate and the lower supporting iron plate are assembled in a fixing frame with a spring supporting iron plate so as to form a closed space, the cable conductor is tightly pressed on the bevels via a wedge pressure block, the periphery of a supporting tube fixedly connected with the insulator is fixed with a handle sleeve via a thermal isolator, and a heat insulating mattress is arranged between the contact surfaces of the end parts of the thermal insulator and the handle sleeve and the end part of the insulator. The structural design is reasonable, the cable conductor joint is pressed tightly, the contact resistance is radically reduced, the heat-producing capability is reduced, the electrode holders are ensured not to be scalding during the continuous welding operation, the cost is lowered, and the operation condition is improved.

Description

technical field [0001] The invention relates to an arc welding device, in particular to a wedge-type electric welding tongs which are used for alternating current and direct current and have remarkable heat insulation effects and are not hot to the hands during continuous welding. Background technique [0002] At present, various electric welding tongs sold in the domestic market are divided into three structures according to the connection mode of the cables and the welding tongs joints: spiral type, pressing plate type, and pressing type. Among them, the spiral and platen structures mainly have the following problems: [0003] 1. There are three heat sources of welding tongs: one is the contact resistance heat generated at the cable joints in the wiring assembly of the welding tongs, the heat is the largest; the second is the radiant heat generated by the welding arc, followed by the heat; the third is The resistance heat generated when the cable is energized, the heat is...
