Description

A kind of non-scald on hand, without the electrode holders of spring

Affiliated technical field

The present invention relates to a kind of arc welding implement, be specially adapted to the manual arc welding of all kinds of alternating current-direct currents, is a kind of electrode holders of long-life non-scald on hand.

Background technology

The electrode holders of our homemade various model specifications at present, owing to constructional reason, in actual production process, all exist many deficiencies and shortcoming: the one, a kind of electrode holders of specification only are applicable to the welding rod in the certain specification diameter range, the welding rod that only is fit to seize on both sides by the arms minor diameter as the soldering turret of 200A, large diameter welding rod is not held under the arm not entered at all, the welding rod that removes to hold under the arm minor diameter as the soldering turret with 500A will be seized on both sides by the arms not firm, easily loose contact or at all can't weld job; The 2nd, handle easily heating is hot, makes the operator feel hot, thereby has influenced operating efficiency, and this mainly is because big electric current flows through the resistance heat that produces when copper staight shank and soldering turret are seized welding rod on both sides by the arms.Some is the radiation from electric arc, is to allow the electric welding operator feel the main cause that scalds one's hand because the loose contact of cable and copper staight shank produces superheating phenomenon.All there is this problem in the electrode holders of domestic all manufacturer production at present.The 3rd, the life-span is short, and the general life-span of electrode holders that we use now is shorter, mainly contains to seize spring on both sides by the arms and drop and seize mouthful rapid wear on both sides by the arms and seize not firm welding rod on both sides by the arms and can't use.In engineering construction, all contact mostly especially in reinforcing bar or steel structure, also, accidentally spring is dropped with regard to making soldering turret catch on these reinforcing bars easily because flowability is big.Our present soldering turret all is casting in bronze, though copper good conductivity hardness is low, makes jaw groove wearing and tearing easily and deepen greatly when constantly seizing welding rod on both sides by the arms, just can't hold firm welding rod under the arm.Another reason is because the staining gradually of the high-temperature dust and the molten strain of splashing, and it is bad that jaw contact with welding rod, and striking sometimes on the weldment but gone on the soldering turret mouth, constantly ablates the jaw groove, burns deeply, just can't hold firm welding rod under the arm more yet.

Summary of the invention

At the above-mentioned deficiency of present electrode holders, the object of the present invention is to provide a kind of electrode holders of the simple and easy long-life non-scald on hand of seizing the size diameter welding rod on both sides by the arms without spring.

The present invention is achieved like this, and our traditional electrode holders are all seized welding rod on both sides by the arms by the structure of two duck-beak types of forming up and down, and holding under the arm of welding rod tightly is that active force with spring is realized.This soldering turret is held the welding rod of much diameters under the arm so just determine to open a how dark mouth groove, so just limited to the welding rod that can seize any size diameter on both sides by the arms because the jaw of duck-beak type is shorter.And the present invention changes traditional thinking, has adopted a reinforcing bar to curve the method for a soldering turret, utilizes the distortion elastic force of reinforcing bar itself to hold tight welding rod under the arm, so just saved original spring, has not fallen problem that soldering turret cannot use with regard to worrying spring.And the elastic force of reinforcing bar itself helps holding under the arm the jail and holds tight welding rod under the arm more than good of spring.Among the present invention welding binding clip has directly been curved a U type, the other end reinforcing bar is curved comes just in time to stick in the U type mouth, as one scissors, lived the welding rod of any size diameter so just can hold under the arm tightly, more do not worry because spring has fallen or lost efficacy and the misgivings that can't use.Because the present invention has adopted iron soldering turret mouth, because iron is than the hardness height of copper, so more durable.And iron jaw can not ablate because of contacting sometimes that bad striking point is gone on the soldering turret mouth, on the contrary also can be at the jaw one deck of burn-oning.Mill is big more more so just not worry grinding darker and darker by jaw.In sum, this is a kind of soldering turret of longevity thus.Owing to be with a reinforcing bar moulding, so a kind ofly especially be not afraid of to fall evil idea and be not afraid of and strike bad soldering turret.

Aspect solar heat protection, the present invention has done following Several Measures: the one, adopted with a bit of cable to be soldered directly on the soldering turret, contact point has been moved on to outside the soldering turret, so can not generate heat because of the loosening of the connecting portion of cable and soldering turret, change over traditional easy loose contact with the tight method of screw.Loose contact is heating, hot easily just, has directly influenced user's production efficiency.The 2nd, the position of this a bit of cable welding is near the soldering turret mouth, and do not allow the handle of principal current by shaking hands, and so just further reduced the heating of handle.Thermal source has only a fraction of electric current by some heats that produce and the jaw conduction is come.By also will putting the heat insulation gum sleeve of insulation at handle part in addition after these technological improvements, the heat that produces at handle part just seldom.So this is a kind of electrode holders of non-scald on hand.

Among the figure 1, the soldering turret body, 2, cable, 3, the pad of cable and soldering turret, 4, welding rod, 5, the last holding head of soldering turret 1 font, 6, the following holding head of soldering turret U type, 7, seize groove, 8,45 degree skewed slots on both sides by the arms

The specific embodiment

Below in conjunction with accompanying drawing the electrode holders of a kind of non-scald on hand of the present invention without spring are described further.

Structural representation with reference to Fig. 1: the 1 whole reinforcing bar of serving as reasons curves the soldering turret body of type among the figure, when brake forming, be bent to the angle of 180 degree, following holding head 6 is bent to the U type, re-using suitable power is pressed onto the last holding head of 1 font in the following holding head of U type, form one the scissors shape, so can hold the tight welding rod of size diameter arbitrarily under the arm, so just hold under the arm tight and held firm welding rod under the arm by self distortion elastic force of soldering turret 1, as shown in Figure 2, on last holding head 5 upper and lower holding head 6, have the V-type groove, be convenient to hold under the arm firm welding rod, can not skid, also have the V-type groove of miter angle at holding head front end place, be convenient to the weld job of rake angle, at soldering turret near a following end of holding head 6 cable of burn-oning, so just the joint of soldering turret and cable has been moved on to outside the soldering turret, directly eliminated the generation of main heat source, because the joint 3 that is welded on the soldering turret body has only several centimetres distance from the soldering turret mouth, so this resistance of several centimetres can be ignored, can not just having generated heat easily of iron because of it, some electric current is gone up holding head 5 through the semi-circular handle part flow direction and is flowed to the welding rod of holding under the arm at jaw more in addition, this just equals all to have in the top and bottom of welding rod the contact-making surface of the electric current of flowing through, thereby further reduced by seizing the resistance heat that the welding rod position produces on both sides by the arms, so produce at the little heat of handle part, because jaw also is made of iron, so wear-resisting durablely do not ablate.

The simple and durable that the present invention becomes soldering turret, cost is lower, is a kind of desirable soldering appliance.
