Abstract
The present invention relates to a copper-saving and heat-resisting electrode holder without scalding hands. With a changed traditional structure, a wedge block fastening mode is used for fastening cable joints to expand contact areas and reduce resistance heat; fastening joints and cables with high heat productivity are moved out of a handle at the same time, so that heat resulting in heating and scalding can not be generated inside the handle any longer. The electrode holder has the advantages of simple structure, copper saving, small volume, stable center of gravity, convenient operation, endurance and no hand scalding.
Description
The present invention relates to a kind of soldering appliance, is the electrode holders that manual electric arc welding is used.
Electrode holders are under the effect of heat-flash radiation, heavy current in welding process, and the problem that electrode holders scald one's hand is in decades, fail to improve the old problem that solves always.
In order to address these problems, domestic " welding " magazine 1982,8 was once reported, and cable is welded on the soldering turret, prevented the hot of soldering turret, but this with the fastening method of welding, and a lot of inconveniences are arranged; U.S. Pat-the 2658133rd not by handle, directly is fixed on the welding cable line on the cable fixed joint of the outer side of handle.But; because bypass cable does not have path protection; but be exposed to the external world; dangerous like this; and no matter always big or small electric current has a cable to hang over subordinate when welding; inconvenient operation can not adapt to various working condition neatly, and the multinomial performance of electrode holders is required reasonably not taken into account.Therefore, the scheme of these non-scald on hand seldom obtains adopting and promoting, and under present realistic situation, the problem that scalds one's hand is ubiquity still, is still a unsolved old problem.
The objective of the invention is in order to overcome deficiency of the prior art, and a kind of new-type non scalding hand electric welding tongs having that is easy to be extended and applied is provided, so that from fact solving the problem that electrode holders scald one's hand.
The present invention is achieved in that in the lower jaw before will the fastening chamber of welding cable by prior art being arranged on handle, the exit passageway of two welding cable lines is set, cable can be drawn from the handle outlet plenum, and when big electric current, can also cable be shifted out from handle, and the bypass outlet plenum outside handle is drawn, the cable of huge heat is directly dispelled the heat in air, reduce the heating factor in the handle to greatest extent.In order to make cable can easily shift out handle, also adopt the sub-assembly technology that known cavity can folding.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, promptly can not have heat generating member in the handle when big electric current, and easy to use at ordinary times, thereby prevents the hot of handle fully and effectively.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Figure (1) is the structural representation of the non scalding hand electric welding tongs having 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 non scalding hand electric welding tongs having.
These electrode holders comprise the handle (6) that clamps the conical voussoir of hand (9) lower jaw guard shield (1) lower jaw (2) (8) vice body guard shield (3) hawkbill body (5) support (7) radiation proof baffle plate (4) and heat shield (6b) arranged.
Cable (not drawing among the figure) is fed in the fastening chamber (2a) of cone-shaped hole of lower jaw (2), squeeze into conical 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), 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 conical 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, through hole (7a), bypass outlet plenum (3a) and the handle cavity (6a) of support all can be able to be made the sub-assembly that cavity can folding.
Claims (2)
1, a kind of forceps for manual electric arc welding of non-scald on hand, the cable fixed joint that is fixed on the outer side of handle by handle, pincers hand, upper and lower jaw guard shield, bit and cable is formed, it is characterized in that: welding cable has two exit passageways, i.e. handle outlet plenum (6a) and bypass outlet plenum (3a).
2, electrode holders according to claim 1 is characterized in that handle outlet plenum (6a) and bypass outlet plenum (3a) are the sub-assemblies that cavity can folding, are convenient to cable and can shift out shift-in easily.
