Abstract
The invention discloses an electrode device, which comprises a cylindrical electrode body, wherein an axially extending channel is arranged on the electrode body; a moveable pushing rod is inserted in the channel; a radial hole is formed in the electrode body; an electrode head is inserted in the radial hole; the bottom of the electrode head is in matching connection with the front end of the moveable pushing rod through a wedge surface; the moveable pushing rod and the electrode head are made of conductive metals; and the moveable pushing rod is connected to a welding host machine. According to the technical scheme, an electrode can be inserted into a pipe fitting, and after a workpiece reaches a to-be-welded position, the electrode head is pushed out, thereby generating an effective pressure between the upper electrode and the welded workpiece as well as between the lower electrode and the welded workpiece and finishing a welding process of the pipe fitting. The electrode head is pushed out after the workpiece reaches a welded position, thereby avoiding abrasion caused by inserting the electrodes into the pipe fitting. When the electrode head is subjected to welding loss, the electrode head can be singly replaced without replacing the whole electrode, thereby reducing maintenance cost and lowering the cost of an enterprise.
Description
Technical field
The present invention relates to welding technology field, particularly relate to the employed electrode assembly of a kind of resistance welding equipment.
Background technology
Resistance welded is that welded piece is pressed between two electrodes, and imposes electric current, and utilize electric current to flow through thermal resistance effect that workpiece contact-making surface and adjacent domain produce is heated to workpiece and melts or mecystasis, makes it to form a kind of method that metal combines.As shown in Figure 1, during operation, top electrode 11, bottom electrode 12 must compress workpiece 13,14, produce welding effect through electric current after, at two workpiece 13, form weldering nuclear 15 between 14 and reach the purpose that fuses.When two workpiece are planar materials or when having enough big space mounting upper/lower electrode; Then this method is able to execute work; When workpiece is tube type material; The problem such as strength that compresses that the electrode that is positioned at pipe pipe will take place can't to be provided with, can't to stretch into and can't produce correspondence can't be reached welding procedure.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of electrode assembly, execute when welding procedure and make in cast and add man-hour, have the wear to electrodes of minimizing, accurately and fast locate and produce advantages such as compressing strength between the effective upper/lower electrode.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of electrode assembly comprises the cylindrical electrode body, and said electrode body is provided with axially extended passage; Plug movable push bar in this passage; Said electrode body is provided with radial hole, plugs electrode tip in this radial hole, and the electrode tip bottom is connected through wedge surface with the movable push bar front end; Movable push bar and electrode tip are that conducting metal is processed, and movable push bar is connected with the welding main frame.
As preferably, said electrode body is that conducting metal is processed, and the electrode body outside is provided with insulating outer layer.Movable push bar can be connected with welding main frame earth polar through electrode body like this, and can avoid producing the electric current distributary phenomenon when welding.
As preferably, the connecting rod that said movable push bar is processed through insulating materials is connected with the push rod cylinder.
In order to reduce the temperature accumulation that continuous welding causes, as preferably, said electrode body is provided with the chilled(cooling) water return (CWR) device.
As preferably, said electrode tip is the replaceable type electrode tip, when consume takes place, can change.
As preferably, electrode body, electrode tip and movable push bar all use brass, chromium zirconium copper or other of identical component to be applicable to the copper product that electrode uses.
The present invention has been owing to adopted above technical scheme, and compares in the past, can electrode be stretched into pipe fitting inside; Arrival needs the position of welding; Again electrode tip is ejected, make between the workpiece of upper and lower electrode and welding and produce efficient pressure, and then reach the welding procedure of pipe fitting.Electrode tip just upwards ejects the wearing and tearing that caused in the time of can avoiding electrode to stretch into pipe fitting after workpiece arrives the welding position.After the welding loss takes place electrode tip, can change electrode tip separately and need not change whole electrode, thereby reduce maintenance cost and reduced the cost of enterprise.

The specific embodiment
Do a detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment 1:
Like Fig. 2, Fig. 3, a kind of electrode assembly shown in Figure 4, comprise cylindrical electrode body 1, said electrode body 1 is provided with axially extended passage; Plug movable push bar 2 in this passage; Said electrode body 1 is provided with radial hole, plugs electrode tip 3 in this radial hole, and electrode tip 3 bottoms and movable push bar 2 front ends are connected through wedge surface; Movable push bar 2 is processed for conducting metal with electrode tip 3, and movable push bar 2 is connected with welding main frame 10.
In the present embodiment, said electrode body 1 is processed for conducting metal, and electrode body 1 outside is provided with insulating outer layer 6.The connecting rod 4 that said movable push bar 2 is processed through insulating materials is connected with push rod cylinder 5.Said electrode body 1 is provided with chilled(cooling) water return (CWR) device 9.Said electrode tip 3 is the replaceable type electrode tip.
As shown in Figure 2, when doing, start chilled(cooling) water return (CWR) device 9 and cool off; The pipe that will weld overlaps to electrode body 1 outside and arrives the location, drives push rod cylinder 5, promotes movable push bar 2 via connecting rod 4 and advances; The inclined-plane of movable push bar 2 front ends can upwards eject electrode tip 3, is exerted pressure by the interior side direction pipe fitting of pipe fitting, drives top electrode cylinder 8 again and top electrode 7 is done downwards apply pressure on the workpiece; This moment, upper/lower electrode produced pressure in the workpiece both sides; Start bonding machine main body 10, produce through electric current and between workpiece and melt nuclear, accomplish the pipe fitting welding procedure.After accomplishing welding, involution top electrode cylinder 8 is done top electrode 7 is upwards mentioned, and involution push rod cylinder 5 is done via connecting rod 4 movable push bar 2 is retracted, and electrode tip 3 drops to original position automatically, and can take out the workpiece that welding is accomplished this moment.
It should be noted that; The specific embodiment that provides in the specification of the present invention only is to the specific descriptions of technical scheme in the invention and non-limiting; For example as shown in Figure 3; The shape of the cross section of the push rod described in the present invention is not limited to the quadrangle form that the present invention adopts, and can also be designed to moulding types of attachment such as triangle or other polygon, and the electrode tip that is upwards ejected also can increase number; Only technical scheme of the present invention is done simple change and adopt essence invention spirit of the present invention, still in protection scope of the present invention.
