Description
Technical field
The utility model is related to ERW steel pipes field, more particularly to a kind of ERW steel pipes electrode compresses and the same step of electrode spacing
Whole experimental provision.
Background technology
ERW (Electric Resistance Welding) is the electricity generated using electric current by electrode and adjacent domain
Thermal resistance, the method welded by compression roller extruding.Profiling thereof makes counterpart both ends for pipe and under the action of compression roller
The V-shaped angular aperture welding section in face, V-arrangement top end point become point.During welding, electric current is directly inputted from electrode, due to collection skin effect
With the effect of kindred effect electric current should be made to be concentrated mainly on v-shaped opening welded corner joint area end face surface layer.At present, country facilities are in electricity
Before source is connected, electrode is first pressed on pipe surface.In welding process, when the temperature of weld seam is influenced be subject to extraneous factor, meeting
Generate fluctuation.Welding temperature is excessively high, can make welding line over-burn, forms perforation；Welding temperature is too low, then burns weld seam impermeable, formed
It is lack of penetration.When occurring too high or too low for temperature, factory can only shutdown adjustment electrode position.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of ERW steel pipes electrode compression and electrode
Pitch-synchronous regulation experiment device.
Technical solution is used by the utility model：A kind of ERW steel pipes electrode compresses and interelectrode distance synchronous adjustment
Experimental provision, including tension spring, electrode fixing device, electrode adjuster.It is characterized in that, the plate connects with electrode

Chain link, the electrode fixing device other end are connected by tension spring with tension spring pressing plate, the tension spring pressing plate and two solid cylinders
Connection, the solid cylinder are contacted with a massive plate with guide rail, and the massive plate with guide rail is fixed, the filled circles
Column is threadedly coupled with two threaded solid hopkinson bars, and two pinion gears, described two pinion gears point are fixed on the threaded solid hopkinson bar
It is not engaged with a gear wheel, wherein gear wheel is driving wheel.Further, the electrode interior opens hole, both ends be equipped with into
Water outlet.The threaded solid hopkinson bar one side is left-handed, one side dextrorotation, and centre is one section of polished rod.
During work, set pretightning force that the electrode is made to be pressed on the plate using the tension spring in advance, by electric current plus
On the electrodes, the opening corner edge of the electrode and the plate forms closed loop.The gear wheel is by rotating band
Synchronous Transmission occurs for the dynamic pinion gear, and the pinion gear drives the threaded rod to rotate, the threaded rod and the cylinder spiral shell
Line connection is translatable by rotating the solid cylinder, and the cylinder drives the tablet to be translatable, described in the tablet drive
Electrode pressing device is translatable, and the electrode pressing device drives the electrode obit, realizes the synchronous adjustment of electrode spacing.
Compared with prior art, the beneficial effects of the utility model are：
1. the compression of electrode can be realized by tension spring, prevent from that slipping phenomenon occurs in plate motion process；
2. by translation of the rotation with moving electrode of gear, the synchronous adjustment of electrode spacing is realized.

Specific embodiment
As shown in Figure 1, setting pretightning force that electrode 14 is made to be pressed on plate 13 using tension spring 7 in advance, electric current is added in electricity
On pole 14, electrode 14 and the opening corner edge of the plate 13 form closed loop.Gear wheel 1 passes through rotation driving pinion 2
Generation Synchronous Transmission, pinion gear 2 drive threaded solid hopkinson bar 3 to rotate, and threaded solid hopkinson bar 3 is threadedly coupled with solid cylinder 4, lead to
Rotation is crossed so that solid cylinder 4 is translatable, solid cylinder 4 drives band guide rail tablet 5 to be translatable, and band guide rail tablet 5 drives tension spring pressing plate 6
Translation, 7 both ends of tension spring are separately fixed at by tension spring hook 8 on electrode fixing device 9 and tension spring pressing plate 6, and tension spring pressing plate 6 drives
Supporting rack 10 is translatable, and supporting rack 10 is connected with electrode fixing device 9 by bolt 12 and nut 11, therefore supporting rack 10 can drive
Electrode fixing device 9 is translatable, and electrode fixing device 9 realizes the synchronous adjustment of electrode spacing with moving electrode 14.
