Abstract

The utility model discloses a Cu-Fe joint-type top-joint electric welding pliers core, wherein the joint of the cable and the welding pliers core is positioned at the upper part of the electric welding pliers core; the electric welding pliers core is made of a Cu-Fe bimetallic material; the copper material consumption is reduced by more than 70%; and the heat transfer is reduced. The electric welding pliers core comprises a solder strip clamp (1), a welding core main body and a cable clamp, and characterized in that the welding core main body is a Cu-Fe bimetallic welding body, wherein the upper part of the welding body is made of a copper material and the handle at the lower part of the welding body is an iron tube (4); the cable clamp is the combination of a fixed arc-shaped red copper clamp (2) and a movable arc-shaped red copper clamp (3); the cable is connected with the upper part of the welding core main body; and the diameter of the cable is configured to contact the solder strip clamp for clamping a solder strip. The electric welding pliers core enables the joint of the cable and the welding pliers core to be positioned at the upper part instead of the lower part of the electric welding pliers core and adopts the Cu-Fe welded joint. The electric welding pliers core can continuously work for 8 hours while the electric welding handle is not hot, and has an ideal use effect.

Description

Copper iron joint type top sub electrode holders core

Technical field

The utility model belongs to the manual electric arc welding soldering appliance, is used for the handgrip of clamping welding rod and the electrode holders core that is connected usefulness of cable specifically.

Technical background

The general manual electrode holders core and the joint of cable all are to kill with jackscrew in electrode holders core bottom on the market.Cable and electrode holders core contact area are few, use cable connector easily to produce oxidation for a long time and generate heat, and it is long to add the copper core again, and the electric welding machine working time is long, and the heat of generation is bigger, and electric weld handle is easy to scald one's hand, and is the difficult problem that the electric welder has a headache very much.The electrode holders core all adopts valuable copper metal, and copper consumption is big, and electrode holders core material cost height increases the welding machine cost.

Summary of the invention

The utility model purpose is to disclose a kind of copper iron joint type top sub electrode holders core, and the joint of cable and soldering turret core has been changed to the top of electrode holders cores, and the electrode holders core adopts copper iron double metal material.Save the copper material more than 70%, and reduced hot transmission.

The utility model composition includes welding rod clamping plate 1 and core wire main body, cable clamp are formed, it is characterized in that: described core wire main body is a copper iron double metal welding body, its top is copper material, the place of holding, bottom is an irony pipe 4, described cable clamp is the fixedly combination of camber red copper clamping plate 2 and movable camber red copper clamping plate 3, cable is connected with the top of soldering turret core main body, and the cable diameter contacts on the clamping plate of clamping welding rod.

The utility model has been changed to the top of electrode holders cores to the joint of cable and soldering turret core from the bottom of electrode holders core, adopt the electrode holders core of copper iron welding point.Fine through practice effect.With 5mm diameter welding rod, repair steel-casting continuously during actual the use, use the 15kg welding rod every day with 400 amperes of big electric currents, continuous operation every day 8 hours, electric weld handle is not warm.Result of use is very good.

The specific embodiment

Traditional electrode holders core, core wire main body all with valuable copper metal, have been wasted a large amount of noble metals, and cable is connected with following solid electrode holder core, and electric current moves in conductor and produces skin effect, and the electrode holders core of solid easily generates heat.As shown in Figure 1, the utility model has changed this situation.The contact of cable diameter is on the clamping plate of clamping welding rod.The welding cable line all is that fine copper wire combines, and current mobility is good, compares with the solid electrode holder core of joint below, has greatly reduced heating.The joint of electric current line and electrode holders core has been changed to the top, adopted copper iron welding point, saved the copper material more than 70%, and reduced hot transmission.

Claims

1. copper iron joint type top sub electrode holders core, form and to include welding rod clamping plate (1) and core wire main body, cable clamp, it is characterized in that: described core wire main body is a copper iron double metal welding body, and its top is copper material, and the place of holding, bottom is irony pipe (4).
