Description

Steel bar frame voller welding machine, electricity conducting means thereof

The utility model relates to a kind of conductive solder device, especially a kind of framework of steel reinforcement seam welder conductive solder device that is exclusively used in the framework of steel reinforcement welding of armored concrete water-supply-pipe and drainpipe.

China produces the framework of steel reinforcement from stress armored concrete water-supply-pipe and reinforced concrete sewer pipe, is to adopt GJGH series framework of steel reinforcement seam welder to twine roll welding to make.The conductive solder device of GJGH series framework of steel reinforcement seam welder is to take power supply to connect the conductive copper plate conduction, and the copper axle through being fastened on the conductive copper plate conducts to electrode wheel, and the electrode wheel of bearing certain pressure, its guide ring muscle welding groove of taking turns cylindrical aligns the ring muscle, circumferential reinforcement is by the rotating mechanism driven rotary, and twine, meanwhile, vertical muscle is dragged by the mechanical transmission structure traction, the pad of vertical muscle and ring muscle is by photoelectric tracking ... finally roll and conduct electricity, and impose elastic pressure in the reinforcing bar pad, the welding of rolling by the electrode wheel on the conductive solder device.But all there are wearing and tearing in various degree in the conductive copper plate of this conductive solder device, copper axle, electrode wheel in service firing.According to statistics, 370 kilograms of framework of steel reinforcement seam welder waste in year copper products, fee of material be more than 6000 yuan, and the lathe machine-team takes, the labor hour expense, and accumulative total is more than 9800 yuan.As seen, the conductive solder device of GJGH series framework of steel reinforcement seam welder is rational inadequately, has both wasted copper product, wastes fund again, but also wastes many labours etc.In addition, also there is the welding current instability in former conductive solder device, and welding spark is big, and welding quality can not get guaranteeing that what often influence was produced normally carries out.

It is good that the purpose of this utility model provides a kind of electric conductivity, and welding current is stable, and spark is little, and quality is good, and project organization is reasonable, economical with materials, and cost is low, can save fund, artificial framework of steel reinforcement seam welder conductive solder device greatly.

The utility model is by electrode wheel, conductive casters, electrode cantilever, compositions such as "T"-shaped connecting rod, brush, brush box, conductive copper plate, conduction copper belt.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model structure vertical view.

The conductive solder device is a part of important device on the framework of steel reinforcement seam welder, the welding that is the framework of steel reinforcement seam welder is finally realized by conductive solder device rolling welding, it is constant that the utility model keeps former seam welder, and new conductive solder device is to be connected with the supporting arm of former seam welder.

The welding electrode of this device wheel (1) rounded ring-type internal taper hole, the center is hollow, matches with conductive casters (2) circular cone end face, and fastening by gland (3), bolt (4).One end inserts the brush (5) of brush box (6), and its arc section contacts with conductive casters (2) cylindrical, and brush box (6) is connected with "T"-shaped connecting rod (11) by insulation board; "T"-shaped connecting rod (11) outer casing spring (12), the other end connect pressure-regulating sleeve (14), the pressure regulation bearing (13) of supporting pressure-regulating sleeve (14) is fastened on electrode cantilever (7) end, electrode cantilever (7) head end is equipped with bearing, connect conductive casters (2) by minor axis (8), electrode cantilever (7) is terminal, conductive copper plate (17) is connected with the supporting arm (15) of seam welder, when being connected and installed, must use insulating pad, insulating sleeve and attachment screw, make it reach specification requirement not only fastening but also insulation.Conduction copper belt (16) one ends connect brush box (6), and an end connects conductive copper plate (17), and (9) are bearing cap, and (10) are grease nipple.

The course of work of the present utility model is: power supply connects conductive copper plate, through conducting electricity copper belt, brush box, brush, conductive casters to electrode wheel, electrode wheel cylindrical guide ring muscle groove aligns and applies pressure to the ring muscle simultaneously, the ring muscle twines with the rotating mechanism rotation, the frictional force of the ring muscle of its rotation, friction drives electrode wheel and rolls, simultaneously because the photoelectric tracking effect, encircle muscle and vertical muscle contact place whenever, the electrode wheel that is rolling is a conductive solder.

The utility model is reasonable in design, and dependable performance adopts the brush conduction not only to conduct electricity very well, and economy and durability; The welding electrode wheel is designed to the circular ring-type of internal taper hole, can effectively save chromium zirconium copper product, and make the meritorious use rate of electrode wheel bring up to 86～88% by 57～60% of original device; And the circular ring-type internal taper hole of electrode wheel assembles conduction mutually with the circular cone end face of conductive casters, and this cooperation is easily installed quick detachable, and is very easy to be reliable, but the continuity that adopts external cooling to be of value to heat radiation and to produce.This conductive solder device electric conductivity is good, and welding current is stable, and welding spark is little, and welding quality is good, and long service life can be saved a large amount of maintenance recruitments, has guaranteed the framework of steel reinforcement quality.

Adopt this conductive solder device, but a framework of steel reinforcement seam welder direct saving brass bar material was 330 kilograms in 1 year, save 18 kilograms of electrode wheel chromium zirconium copper, 3～4 18～24 kilograms of copper coins (conductive plate), amount to 370 kilograms of material weight, fund is more than 6000 yuan, and when saving the machined platform, and labour's recruitment One-Shift Costs accumulative total is more than 9800 yuan.The cement products industry of China is many more than various schools of thinkers, the factory that produces water-supply-pipe, concrete drain tile also is no less than various schools of thinkers, and factory of every family all has the framework of steel reinforcement seam welder of certain platform number, if can adopt this conductive solder device, will save wide variety of materials, fund for country, and guarantee product quality with advanced person's science and technology, and increase economic efficiency, be the more wealth of society's accumulation.
