Abstract

A kind of heat insulation electrode holder.Changed traditional structure,, increased contact area, reduced resistance heat the fastening mode of fastening employing voussoir of cable connector; Simultaneously that caloric value is big fastening and cable all shift out handle, make no longer include heat in the handle and arrive the heating and hot.

This soldering turret is simple in structure, economizes copper, and volume is light and handy, and stable gravity center is easy to operate.Maximum characteristics are durable non-scald on hand.

Description

Heat insulation electrode holder

The present invention relates to a kind of soldering appliance, is the electrode holders that manual electric arc welding is used.

Electrode holders are in the heat-flash radiation in welding process; Heavy current and the resistance heat that produces under the effect of heat conduction and thermal convection current, very easily scald one's hand in handle place generation high temperature and thermal-radiating baking.And the problem that electrode holders scald one's hand is the old problem that thoroughly is resolved of always failing in decades.

In order to address these problems, general just with the screw fastening of fastening soldering turret as far as possible tightly, because contact area is limited, the joint still generates heat hot, domestic " welding " magazine 1982,8 was once reported, be welded in cable on the soldering turret and adopt double-deck handle to prevent to scald one's hand, more in addition Chinese patent application 87203419; 87203420; 87210592; 86201153; 85204252; 86209018; 86207847 have all proposed some improved plans, because the mount inconvenience, and seldom obtain adopting and promoting.(to fix with screw and special-purpose clamp as radiation shield; The thin heart yearn of cable is difficult to the fastening welding with soldering turret) all do not have from solving the hot problem of soldering turret heating in essence, all sidedly.

The objective of the invention is to provide a kind of new-type electrode holders, can thoroughly solve the problem that electrode holders scald one's hand.

The present invention is achieved in that the fastening with fastening welding cable moves to the outside of handle, thereby increases the heating factor in heat conducting distance and the minimizing handle; Adopt the fastening mode of voussoir, make the contacting of whole wall gross area in welding cable and fastening chamber, reduce resistance heat; Fastening chamber is set directly in the lower jaw, has reduced the consumption of copper; Also can optionally from handle, shift out cable in addition, the cable of huge heat is directly dispelled the heat in air, reduce the heating factor in the handle to greatest extent; Set up one without screw and clamp just can loading, unloading easily the radiation proof baffle plate protect cable and the back of the hand.

The present invention compares with original technology, and is simple in structure, economizes copper, and can accomplish not have heat generating member in the handle, thereby prevent the hot of handle fully and effectively, and also easy to use.

Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.

Figure (1) is the structural representation of the heat insulation electrode holder of proposition according to the present invention, and figure (2) is the section of structure of figure (1), and figure (3) is the part schematic diagram in addition among the figure (1).

Concrete structure and working condition below in conjunction with structural representation figure (1) profile figure (2) and other part figure figure (3) detailed description heat insulation electrode holder:

These electrode holders comprise the handle (6) that clamps hand (9) lower jaw guard shield (1) lower jaw (2) first taper voussoirs (8) vice body guard shields (3) hawkbill bodies (5) supports (7) radiation proof baffle plates (4) and heat shield (6b) arranged.

Cable (not drawing among the figure) is fed in the fastening chamber (2a) of first conical through-hole of lower jaw (2), squeeze into first taper voussoir (8) then from the center of cable end face and make it fastening.Cable can be drawn from handle cavity (6a); Cable also can be drawn from the bypass outlet plenum (3a) of vice body guard shield (3), and is fixing through rack ventilating hole (7a).And then the last breach (4a) of radiation proof baffle plate (4) snapped in bypass outlet (3c) or the cable that vice body guard shield (3) and following breach (4b) snap in vice body guard shield (3).

The aperture (1a) of the positive front of lower jaw guard shield (1), its effect are to unload lower jaw guard shield (1), just can be often disclose with the welding rod afterbody easily to clash into first taper voussoir (8) into aperture (1a) that cable is obtained once more is fastening.(in order to avoid expand with heat and contract with cold loosening).

In order to make cable can shift out handle easily, can be with the through hole (7a) of support, bypass outlet plenum (3a) and handle cavity (6a) all can be made the sub-assembly that cavity can folding.

Claims

1, a kind of heat insulation electrode holder is made up of handle (6) lower jaw (2) lower jaw guard shield (1) vice body guard shield (3) radiation proof baffle plate (4) pincers hands (9), it is characterized in that:

A, the bypass outlet plenum (3a) that can draw the welding cable line arranged in that handle (6) is preceding;

B, the fastening chamber of cable (2a) are to be set directly in the lower jaw (2), and the voussoir (8) that matches is with it arranged;

C, radiation proof baffle plate (4) have the last breach (4a) and the following breach (4b) that can snap in cable or bypass pipe (3c) that can snap in vice body guard shield (3);

There is an aperture (1a) front of d, jaw guard shield (1);

E, the rack ventilating hole (7a) of an attached cable is arranged.

2, electrode holders according to claim 1 is characterized in that handle (6) and vice body guard shield cavity (3a) can make the sub-assembly that cavity can folding.

3, according to claim 1,2 described electrode holders is characterized in that heat shield (6b) is arranged in handle (6).

4, electrode holders according to claim 1 is characterized in that the welding cable line can be positioned at the outside of handle (6), also can be positioned at the handle cavity (6a) of handle (6).
