plate, screw a 2-M12 nut into the positioning plate, then follow the bar which is fixed by the nut
in the end.
In these two kinds of position, the circular adjustable knob is installed at the back of
angle iron.
2.6 Adjustment of the braking installation
2.6.1 Adjustment of the upper die:
Loosen the screw bolt, the upper die will come off the machine. If you don’t want the upper
die come off the machine or install another new mould plate, you can put a piece of hard wood
(25,25,160mm) or the other similar materials on the concave mould plate, turn the handle and
raise the concave mould plate until the wooden piece get in touch with the upper die (form
plunger).
After assembling the new die, all the fasten bolts of the die should be tightened up. In
some cases, especially the using of marrow die, it is necessary to put a piece thin paper
between the upper die and the lower die.
2.6.2 Adjustment of the cross girder
To make the bending work smoothly, and separate the formed metal that between the
upper die and the lower die form being blocked, you must adjust the crossbeam.
First, please put a steel plate (its width and thickness must be in the range of the
machine’s range) on the concave mould plate, then turn the handle carefully to raise concave
mould plate. Loosen the fasten bolt of the crossbeam when the upper die (form plunger) getting
in touch with the processing metal plate, after that, in order to fix the crossbeam, you can adjust
the screw which on the crossbeam, at first, tighten up all the fasten screws. During this period,
the handle is not fixed to turn an angle of 360 degrees. Brake a piece of metal plate that with
game width and thickness on both side of the bending system, their angle should be similar, the
job should be excessively braked when you turn the handle and fully brake the job.
2.7 Adjustment of the shearing installation
You should adjust the zero-clearance of the upper cutter and the lower cutter.
Adjustment of the lower cutter:
Unload the pressing plate, loosen the fasten screw and the two adjustable screws of the
working table, turn the handle and make the upper cutter near the cutter on the working table,
tighten the fasten table when the machine is working. Install the pressing plate once more and
ensure that it runs parallel with the upper cutter.
Adjustment of the positioning plate:
During the period of the shearing, there will be a powerful
strength produced in the middle
of the cutter, in order to avoid the clearance that between the upper and lower cutter, you
