Description
Technical field
This application involves steel rail flash welding machine fields, are a kind of fixed flashes of light that celectome is pushed away equipped with segmented specifically
Welding machine automatic pressure-maintaining Tui Liu mechanism.
Background technique
Currently, rail used in railway traffic is all to weld the gapless line of steel mill's production in rail welding plant or with welding the base of the rail
After be routed on route, to constitute gapless track.Rail welding is essentially all in rail welding plant or with welding the base of the rail using fixation
Formula steel rail flash welding machine, welding line joint quality are stablized, and have welding quality judge, welding data collecting and store function；Weldering
After the completion of connecing, overlap to be cut down at high operating temperatures.Currently, rail welding plant or with welding the base of the rail common fixed flash welder
It is broadly divided into direct current rail flash welding machine and AC flash welding machine.AC flash welding machine and direct current flash welder are due on the source of welding current
Difference, cause to be very different on device structure.Direct current flash welder is more complex relative to AC flash welding machine structure, just
Property is good, but volume is big, inconvenient maintenance, price.Direct current flash welder realizes automatic pressure-maintaining substantially and pushes away tumor.AC flash welding machine
Easy to maintenance due to small in size, cost performance is high, applies in rail welding plant and the weldering base of the rail also relatively broad.
Existing frequently-used fixed AC flash welding machine is essentially all non-pressure-maintaining tumor pushing, rather than pressure-maintaining tumor pushing is be easy to cause
Defect, overlap on steel rail welding line are thicker and electrode welder is easy to wear during welding pushes away tumor and pushes away celectome seat guiding axis pole
Easily-deformable the problems such as need to regularly replacing.Commonly to push away celectome be also that conventional two halves formula pushes away celectome, larger, the knife that pushes away tumor power needed
Body is easily-deformable, and cannot be fully disconnected overlap during pushing away tumor, needs manual intervention.Commonly pushing away celectome seat is also two halves formula
Structure, push away celectome and be mounted on tool apron, be easy dislocation when tool apron closes up up and down, need to manually adjust, tool apron using it is common not
Rust steel material, intensity is low, easily-deformable.
A kind of known quick pressure maintaining pushes away convex DC railway rail flash to the patent (Chinese patent of welding machine
CN107671403A the pressure-maintaining tumor pushing structure in) can be only applied to fixed DC flash welder, may not apply to AC flash
Welding machine.Known a kind of machine for flash-butt welding (Chinese patent 98105796.9), by the academy of sciences, Ukraine horse electric welding
Research institute designs and develops.Pressure-maintaining tumor pushing structure in its equipment, the folding for pushing away celectome uses the structure of eccentric wheel guide pad, more multiple
Miscellaneous and inconvenient maintenance, pushing away celectome, pushing away celectome seat also is conventional two-half structure.
In conclusion existing Flash Butt Welding pressure-maintaining tumor pushing mechanism is multiple in the presence of poor tumor effect, cutter hub intensity difference and structure is pushed away
The disadvantages of miscellaneous not easy to repair.
