Description
Technical field:
The utility model relates to a kind of manual electrode holders that weld usefulness, is to have novel pair of pressure handle electrode holders of three pincers sheet, two springs and two pressure handles up and down.
Background technology:
At present, the manual electrode holders of extensive use have two pincers sheet, a lever and pressure handles up and down, and there are following four aspect problems in actual use in the electrode holders of this structure:
(1) crimping cable the end of a thread is only used 2 screws, makes joint contact defective tightness, and electric conductivity is bad, has more electric heating to produce in the joint, and the heating of soldering turret lever is scalded one's hand, and during practice was used, it was universal phenomenon that soldering turret scalds one's hand; It is generally acknowledged it mainly is the heat that the conduction of welding rod arc heat comes, in fact because the contact area of welding rod and jaw is less, the heat that the conduction of welding rod arc heat comes is also few, and more heat mainly is that the electric heating that the welding connector loose contact produces causes soldering turret to send out Hot.
(2) hold-down screw of support and lever is positioned at the lever front end, and support insertion lever length is generally shorter, when press handle changes welding rod, hold-down screw is stressed bigger, cause the fragile and brisement of screw hole portion, soldering turret damages that nearly half phenomenon is arranged is exactly thisly to fall not pacifying the phenomenon that can't use again in the practice;
(3) jaw very easily burns out and can't re-use.It is that jaw burns out and can't re-use that a greater part of damage phenomenon is arranged in the reality.Because the groove of jaw is changeless, and all be triangular shape groove rather than semicircle basically, be that line contacts with the welding rod steel core of different-diameter in the use, its contact area is very small, compare insignificant with the cross-sectional area of steel core and the cross-sectional area of cable core, it is " pinching neck " point in the welding current passage of low-voltage and high-current, thus in welding, very easily produce electric shock, and progressively development and the final jaw that damages.Common in the market various soldering turrets, the electric shock damage in various degree of all very fast appearance in jaw place in use for some time, groove shoals gradually or flattens disappearance, make more difficult clamping of welding rod and then easier electric shock and damage jaw, form vicious circle, finally thoroughly can't use, make the soldering turret lost of life.Present various soldering turret is under situation about using continuously 8 hour day shift, and the only wheat harvesting period that the life-span is short long three to four months, causes no small economic loss for bigger enterprises of manual electric arc welding workload such as shipyards.
(4) the unstable easily swing of welding rod clamping.Traditional soldering turret all has only a spring supporting a pressure handle, promptly has only a pair of relative clamping welding rod of sheet that clamps up and down, and for newer soldering turret of initial period, it is lighter to shock by electricity, and compresses with the groove effect by spring force and still can clamp welding rod.And after groove has certain electric shock damage, constraint ability to welding rod after groove shoals descends greatly, and the coarse injustice of jaw after the electric shock, with contacting of the welding rod steel core face of cylinder also no longer is the line contact, but peak contacts with the point on the welding rod face of cylinder, for the so little contact area of a contact, though the big frictional force that produces of spring force is very little, so the very easy swing of welding rod is unfavorable for high-quality and efficient welding easily.When groove does not damage, digonous and the upper pliers plate of groove is clamped welding rod from three angle butt welding bar application of forces, clamp up and down after groove damage flattens sheet at two points of 180 degree relative directions up and down to the steel core application of force, most of chucking power has balanced out the top by steel core, and two point of applications are relative up and down, on the direction of welding rod extended line, only be equivalent to have an anchor point, because 2 ability decision straight lines, so have only an anchor point can't overcome the welding rod dancing, and because lever principle effect: only needing has less external force effect at welding rod welding end, just can produce bigger rotation knob square at jaw anchor point place, very easily make the welding rod swing, be unfavorable for welding.After the unstable easily swing of welding rod clamping, the electric shock phenomenon is aggravated rapidly, and rate of decay improves, so traditional soldering turret life-span is all very short basically, domestic and international many soldering turret factory continues to do many improvement, but effect is unsatisfactory, and becomes a difficult problem of industry.
