Description
Technical field
The present invention relates to a kind of seam welder member, is a kind of seam welder lower electrode device specifically.
Background technology
Seam weldering is claimed in roll welding again, is the cylindrical electrode that replaces spot welding with a pair of circular electrode, and the workpiece of welding is mobile 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, the DC current of also 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 jar, 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 copper sheathing support fixation electrode wheel; And with the inside and outside circle of copper sheathing conduction; Its concrete structure is that electrodes conduct rod one end necking part socket one electrode rotates copper sheathing; Copper sheathing and welding electrode are taken turns borehole jack and are connect, and welding electrode is taken turns through electrode wheel catch and fastening bolt and is fixedly connected with electrodes conduct rod necking down end, and welding electrode is taken turns and the electrodes conduct rod contracts, and shoulder socket one welding electrode is taken turns pad.Top electrode is descending and apply the pressure about 70kg under the effect of cylinder pressure during work; When electrode rotates, have powerful operating current (>=800A) through and discharge very big heat and produce high temperature; The 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 so 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 spark damage copper sheathing and upper/lower electrode during work and take 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.With the processing hydraulic fuel tank is example: will change a copper sheathing with after more than 10 of the every processing of 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.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of high efficiency is provided, seam welder lower electrode device and supporting base that the production product price is low.The object of the invention is realized through following technical proposals: the present invention includes electrode bar, welding electrode wheel, set bolt, conductive lubricating oil oil filler, cooling water channel; It is characterized in that: also be provided with conductive shaft rotation seat, conductive electrode turning cylinder, 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, and the welding electrode wheel is through being bolted to friction electrode wheel front end, and friction electrode wheel wheel footpath is 1/2～2/3 of welding electrode wheel; Conductive electrode turning cylinder rear portion connects one stud; Be with pad, spring, back-up ring, packing ring, locking nut on the stud successively, 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 through the electrode bar set bolt.
Described conductive shaft rotation seat end face directly is 5/6～1 of friction electrode wheel wheel footpath.
The inside and outside circle of one aspect of the present invention conduction wheel shaft rotating part increases and increases, and its inside and outside circle conductive area is increased, and 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 tens of times; Reduce coefficient of friction; Reduce caloric value, reduced temperature, can lesion electrode.Speed of welding fundamentally is improved; Because electric current is many advantages such as zero crossing, secondary no induction reactance not, welding quality also has clear improvement simultaneously, has improved sweating heat efficient; 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 practiced thrift more than 80%), reduced the power of power supply, the power supply general power is reduced to about 150KVA by 200 original～300KVA, and power consumption reduces 30%～50%.
Use seam welder lower electrode device of the present invention will process 200 above hydraulic oil containers at least and just can change reconditioning rotation copper rod and friction electrode wheel, repair the welding electrode wheel simultaneously, 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.
