Abstract
The present invention relates to a heavy-current continuous power transmission gun specially-used for continuous welding electrode. Its machine core includes two pinch mechanisms which are symmetrical about axle wire, and the continuous welding electrode can be fed along the axle wire. The pinch mechanism includes two rotating wheels which are connected by driving-band, and one metal electrode is installed on every pitch of the driving-band, and on the metal electrode, there is a small boss correspondent to the width of conducting groove of the welding electrode, and the metal electrode can pinch the welding electrode and make it move forward, and at the same time it can feed power to the welding electrode by means of its sliding friction on the conducting plate parallel to the axle wire.
Description
The present invention is applicable to a kind of heavy current continuous transmission gun that is exclusively used in continuous covered electrode.
The existing very long commercial Application history of at present general manual covered electrode, it is good to have the weld metal inherent quality, the appearance Forming Quality is good, cost is low, wide adaptability, welding equipment are simple, can all position welding, advantage such as the scope of application is wide.But stick electrode also exists poor continuity, critical defect that welding efficiency is low, needs often to change welding rod in the welding process, causes welding efficiency low, and polylinker influences weldquality.Its power transmission mode is the static transmission of electricity of tail end clamping, and electrode holders and welding rod contact resistance are very big, and caloric value is big in the use, limited by radiating condition, allows the current density passed through limited, has limited speed of welding.The gas-shield automatic welding that uses has solved the problem of continuous welding at present; but because welding wire surface do not have coating, exist also that weld metal is of poor quality, the moulding of weld seam appearance is poor, the cost height, can only weld several limited metals, bad adaptability, equipment is complicated and heavy, to shortcomings such as working condition requirement height.In addition, owing to lack the stabilising arc effect of coating, splash phenomena is serious, not only influences workpiece surface quality, and welding material waste rate reaches 10～15%.
People are seeking the novel wlding and the equipment of the comprehensive above-mentioned two kinds of weldering method advantages of a kind of energy always in decades.
The purpose of this invention is to provide a kind of big electric current transmission gun, realize the continuous welding of covered electrode for the continuous wire feed of continuous welding electrode, continuous power supply.
The present invention special-purpose continuous welding electrode be a kind of extremely long covered electrode of tubular, joint length that coils into, open an electric welding groove every a fixing pitch on the welding rod, the core wire of conductive trough part is exposed, is convenient to feed.
The present invention includes housing, arc current lead-in wire, the rear end of housing, front end have welding rod import, outlet, have in the housing one along the axis symmetrical movement, continuous welding electrode is carried along the axis of movement in housing; Described movement comprises two pinch mechanisms that are symmetrical in the axis, described pinch mechanism comprises two wheels, the driving-belt of ining succession between two wheels, the inner edge of driving-belt is parallel to the axis, on the driving-belt on continuous welding rod the affixed metal electrode of the length of a pitch, the end width of metal electrode and the width of the conductive trough on the continuous welding electrode adapt, metal electrode is connected with described arc current lead-in wire electricity, corresponding metal electrode is clipped on the conductive trough of welding rod in couples on the pinch mechanism of both sides, axis, the metal electrode one side is advanced with driving-belt clamping welding rod, and one side is with arc current feed-in core wire; Transmission mechanism comprises a motor, and this motor drives described pinch mechanism by a gear.
Realize that preferred mode of the present invention is two wheel employing gears of described pinch mechanism, driving-belt is a chain.
Further, realize that preferred mode of the present invention is that the both sides, axis of described movement are connected with the electroplax that send that is parallel to described axis, send electroplax to be connected with arc current lead-in wire electricity, the described electroplax that send has and the rigging position that is positioned at the metal electrode sliding friction on the driving-belt inner edge.Metal electrode one side clamping welding rod advances, and one side is being sent the feed that slides on the electroplax.
Advantage of the present invention be to continuous welding electrode dynamically, continuously, the multiple spot transmission of electricity, each metal electrode is by cooperating feed of a wire feed with conductive trough on the welding rod over the ground.Each metal electrode gyroscope wheel stream on driving-belt send electricity, arbitrary moment always have many to metal electrode to the welding rod feed, keep sending the continuity of electricity, multiple spot send electricity also to help increasing current density simultaneously; With regard to single electrode, just no longer transmission of electricity when turning to the driving-belt outside, thereby obtain one period cool time, its transmission of electricity time is of short duration and spaced, power transmission mode unlike manual electrode holders continuous static, thereby allow just to have increased arc current on the whole by bigger electric current, accelerated speed of welding.
Further set forth the present invention below in conjunction with accompanying drawing by embodiment:
Fig. 1 is a positive view of the present invention
Fig. 2 is the cutaway view of bowing of the present invention
With reference to accompanying drawing
The present invention includes housing 2, housing 2 bottoms have handle 14, and arc current lead-in wire 15 penetrates in the cavity from handle 14 bottoms.There is one in the housing 2 along the symmetrical movement of axis A-A, housing 2 rear ends and A-A intersection, axis have welding rod input port 12, housing 2 front ends and A-A intersection, axis have welding rod delivery outlet 1, and continuous welding rod 22 is carried along axis A-A in housing 2.Described movement comprises two pinch mechanisms that are symmetrical in axis A-A, and described pinch mechanism comprises two travelling gears 3,10, the driving-chain 7 of ining succession between the travelling gear 3,10, and driving-chain 7 is parallel to axis A-A near the inner edge of axis A-A one side.On the driving-chain 7 on continuous welding electrode the affixed metal electrode 5 of the distance of a pitch, an affixed small lugs 6 that adapts with welding rod conductive trough width on the metal electrode 5, the corresponding metal electrode is clipped on the conductive trough 23 of welding rod 22 in couples on the pinch mechanism of A-A both sides, axis.Gear 3,10 the axle 4,11, bearing 20,13 can conveniently fixedly mounting according to housing 2 inner space position arrangements.A-A both sides, axis have be parallel to described axis send electroplax 8, send electroplax 8 to connect arc current lead-in wires 15, send electroplax the inboard thickness that equals described metal electrode 5 to the distance of axis A-A.The inboard at metal electrode 5 middle parts is fixed in driving-chain 7, and the affixed small lugs 6 in the outside at metal electrode 5 middle parts is used for clamping welding rod and feed.Metal electrode is used to import arc current in two ends up and down, and correspondingly conductive plate 8 also is divided into upper and lower two that are parallel to each other, and its distance of separation and height adapt with metal electrode 5.Transmission mechanism comprises a high-speed electric expreess locomotive 17, and the switch of buncher 17 is contained in the place of housing 2 surperficial easy operatings.Speed change gear is made up of gear 18,19, and motor 17 drives the drive 3 of described pinch mechanism by this speed change gear.
