Description
Technical field
The utility model relates to a kind of seam welder member, is a kind of seam welder lower electrode device specifically.
Background technology
Roll welding claims again seam weldering, is the cylindrical electrode that replaces spot welding with a pair of circular electrode, and the workpiece of welding is movement between rolling disk, produces the method that the seal-weld of the mutual lapping of nugget one by one welds workpiece.Alternating-current pulse electric current or amplitude modulation electric current are generally adopted in roll welding, also the DC current of available three (list) commutating phase, intermediate frequency, high frequency.Roll welding is widely used in the plate sheet welding of airtight container in oil drum, can tank, radiator, aircraft and automotive oil tank, rocket, the guided missile, and general throat thickness is in veneer 3mm.What existing seam welder lower electrode device adopted is that copper sheathing supports the fixed electrode wheel, and with the inside and outside circle of copper sheathing conduction, its concrete structure is that electrode conducting rod one end necking part is socketed electrode rotation copper sheathing, copper sheathing and welding electrode wheel borehole jack connect, the welding electrode wheel is fixedly connected with electrode conducting rod necking down end by electrode wheel catch and fastening bolt, and the welding electrode wheel is socketed welding electrode wheel pad with electrode conducting rod contracting shoulder.Top electrode is descending and apply pressure about 70kg under the effect of cylinder pressure during work, when electrode rotates, have powerful operating current (〉=800A) by and discharge very large heat generation high temperature, contact and the conductive area of taking turns because of the copper sheathing support electrode are little, the dynamic friction that can ceaselessly revolve when working because of electrode again is therefore be easy to the copper sheathing inside and outside circle is pulled damage.Be difficult to closely touch mutually between copper sheathing and welding electrode wheel or be worn after the gap increases when copper sheathing, under powerful operating current, can produce the spark damage copper sheathing during work and upper/lower electrode is taken turns.So often change copper sheathing and reconditioning electrode wheel, very trouble, operating efficiency is low, the electrode wheel service efficiency is low, cost is very high.Take the processing hydraulic fuel tank as example: will change a copper sheathing with after more than 10 of the every processing of the bottom electrode of this structure, fee of material+processing charges+labor hour expense (reconditioning electrode) cost is about 56 yuan, and at most only can process about 80 every day.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high efficiency is provided, seam welder lower electrode device and supporting base that the production product price is low.The purpose of this utility model realizes by following technical proposals: the utility model comprises electrode bar, the welding electrode wheel, set bolt, the conductive lubricating oil oil filler, cooling water channel, it is characterized in that: also be provided with the conductive shaft rotation seat, the conductive electrode turning cylinder, the friction electrode wheel, spring attachment, the electrode turning cylinder is contained in conductive shaft rotation seat center, the front end close-fitting connects a conduction friction electrode wheel, the welding electrode wheel is bolted on friction electrode wheel front end, friction electrode wheel wheel footpath is 1/2～2/3 of welding electrode wheel, conductive electrode turning cylinder rear portion connects one stud, overlap successively on the stud pad is arranged, spring, back-up ring, packing ring, locking nut, whole conductive shaft rotation seat then is fixed by bolts to the output electrode nose, and electrode bar is connected with the conductive electrode rotation seat by the electrode bar set bolt.
Described conductive shaft rotation seat end-face diameter is 5/6～1 of friction electrode wheel wheel footpath.
The utility model conducts electricity on the one hand the inside and outside circle of wheel shaft rotating part and increase to increase, its inside and outside circle conductive area is increased, the more important thing is increases a conductive shaft rotating shaft base and friction electrode wheel, and use the spring compression plane, and welding electrode wheel and friction electrode wheel end-face friction conductive area are increased, the area that electric current passes through increases decades of times, reduce coefficient of friction, reduce caloric value, reduced temperature, can lesion electrode.Speed of welding fundamentally is improved, because electric current is zero crossing, secondary without many advantages such as induction reactance not, welding quality also has clear improvement simultaneously, has improved welding thermal efficiency, avoid excessive and the splashing of causing of unit are electric current, thereby welding quality improves greatly.Improved service life, reduced operating cost (production efficiency improves more than 4 times, and production cost is saved more than 80%), reduced the power of power supply, the power supply general power is down to about 150KVA by 200 original～300KVA, and power consumption reduces 30%～50%.
Use seam welder lower electrode device of the present utility model will process at least 200 above hydraulic oil containers and just can change reconditioning rotation copper rod and friction electrode wheel, repair simultaneously the welding electrode wheel, and cost is about 80 yuan.And can process about 800 every day at least, and operating efficiency has improved greatly, and the service efficiency of equipment has also improved greatly, and cost is but very low.
