Abstract
The utility model relates to the improvement of the current contact nozzle of an automatic submerged-arc welding machine, mainly comprising a main conductive plate, a still conductive plate, a movable conductive plate, screw bolt nuts, a spring bushing, etc. The utility model is characterized in that the movable conductive plate and the still conductive plate which are provided with grooves replace two rolling wheels on the original current contact nozzle. The service life of the current contact nozzle is extended, the overhaul workload of the current contact nozzle is reduced, contact resistance is reduced, and electricity is saved.
Description
The utility model belongs to operation moulding class, relates to metal processing welding field, is a kind of improvement of automatic submerged arc welding machine ignition tip.
Be welded with manual welding and weld two big classes automatically, big for welding capacity, the welding occasion that quality requirement is high, the normal automatic submerged-arc welding of adopting more.At present, the ignition tip of automatic submerged-arc welding adopts roller ignition tip as shown in Figure 1 usually.The roller ignition tip is made up of two wear-resisting copper rollers 4 and 6 that are contained on conductive plate 2 and 3.On the copper roller 4 main 6 groove of leading welding wire 1 is arranged all, welding wire 1 is clamped between two rollers 4 and 6 by the tension force of spring 8, and the spring tension size is regulated by screw nut 7.The shortcoming of this ignition tip is because when welding; high-temperature fusion welding slag and metal melt regular meeting are splashed on the groove of copper roller 4 and 6; make the groove obstruction on copper roller 4 and 6 and lose the effect of guiding welding wire 1, and loose contact, resistance strengthens; need often stop the weldering maintenance; welding slag and fused mass on cleaning roller 4 and 6 grooves, and frequent recopper roller 4 and 6 more also, the copper roller lost of life; maintenance cost increases, and real is inconvenience.
The purpose of this utility model is for overcoming the defective of above-mentioned existence, and improves on former ignition tip, promptly cancels the copper roller, in conductive plate body top one side groove is set directly to contact with welding wire, as shown in Figure 2.Fig. 2 is the utility model ignition tip structural representation.In Fig. 2, the 1-welding wire; The 2-led panel, the upper end hollow pipe has a hole and upper pipes endoporus to link in the lower end, for leading welding wire 1 usefulness; The quiet conductive plate of 3-, lower end one side is provided with the jag of two with grooves, and for pilot welding wire 1 usefulness, piece number 2 and 3 is all used the copper alloy made wear-resisting, that resistance is little; The 4-bolt nut; The 5-bolt nut; 6-moving conductive plate, iron or copper alloy system, lower end one side has the groove jag that serves as a contrast copper alloy; The bolt of 7-band major part; The 8-spring; The sleeve pipe of 9-band screw thread; The 10-nut, piece number 7,8,9,10 is combined into one group of pogo barrel, can produce spring force and make moving conductive plate 6 upper ends away from led panel 2, thereby moving conductive plate 6 lower ends are pressed on the welding wire 1.
When welding, welding wire 1 at first extends between moving conductive plate 6 and the quiet conductive plate 3 by the hollow pipe of led panel 2, because the tension force of spring 8 makes the lower end groove (dotted line place) of moving conductive plate 6 and two grooves in lower end (dotted line place) of quiet conductive plate 3 tightly push down welding wire 1.Owing to directly contacting, welding wire 1 and two conductive plates 3 and 6 top grooves save two copper roller contacts, reduce contact resistance, simultaneously, during welding, the groove that welding wire 1 advances with conductive plate 3 and 6 is a CONTACT WITH FRICTION, conductive plate 3 and 6 and the contact portion groove of welding wire 1 can not expose out and stopped up by the welding slag fused mass.The maintenance and the replacing of ignition tip have been avoided.
Adopt the utility model ignition tip to carry out the automatic submerged-arc welding, ignition tip is difficult for stopping up, and has reduced the shutdown maintenance workload, has prolonged ignition tip service life, has reduced contact resistance, power saving.The utility model ignition tip successfully is applied to welcome by factory on the MZ-1 type DC automatic submerged arc welding.
Claims (2)
1, a kind of automatic submerged arc welding machine ignition tip, mainly form, it is characterized in that the lower end one side-prominent end of quiet conductive plate 3 and moving conductive plate 6 is equipped with the groove of walking for welding wire 1 by bolt nut 4 and 5, one groups of pogo barrels of led panel 2, quiet conductive plate 3, moving conductive plate 6, connection usefulness.
2, automatic submerged arc welding machine ignition tip according to claim 1 is characterized in that the groove on moving conductive plate 6 and the quiet conductive plate 3 partly is to make with wear-resistant copper alloy.
