Realization it can be acted on when hydraulic pressure deflection compensation works, while when hydraulic pressure deflection compensation does not work, middle underbeam can pass through positioning
The effect of pin recovers to reset condition, avoids middle underbeam long-term use from can not recovering nature；
2nd, spacer sleeve thickness is more than the lower cantilever thickness in centre and two bakelite plate thickness sums, middle underbeam just can be with two
Alignment pin is that the centre of gyration carries out amount of deflection revolution, and middle underbeam can carry out amount of deflection as needed and be arched upward to camber, also easily
Recover nature, avoid welding stress and weld problem on deformation of the underbeam under long-term stress effect；
3rd, scratch oil compensating cylinder and run through preceding underbeam, middle underbeam and rear underbeam, and preceding underbeam and rear underbeam are supported on and scratch oil compensating cylinder
Bottom, scratch oil compensating cylinder expansion link and middle underbeam contact be connected；Repairing cylinder working is scratched, the piston rod for scratching oil compensating cylinder stretches out top
Underbeam among rising, so that middle underbeam deflection deformation is compensated to ensure bending precision, oil compensating cylinder mistake is scratched at the end of bending
Pressure, middle underbeam set back, and middle underbeam is freely scratched and mend and reset；
4th, apparatus structure design advantages of simple, easy installation and removal, and bolt assembly and locating pin structure are employed,
Avoiding bender underbeam can be deformed in long-term use, improve bender bending precision, improve productivity ratio, reduce
Percent defective, therefore, has good value for applications.
