These
Press Brakes feature three operational modes for providing greater
convenience to the operators as well as possibility of least fatigue. These
operational modes are:
Inch Cycle : These are used for setting bed angle depth stroke with
the ram movement (up down) controlled at any described position from foot
switches
Auto Cycles : This cycle (Approach-Pressing-Return) is repeated once
selected and is useful for continuous repetitive work where stroke length
needs to be adjusted to suit job and operators speed and rhythm.
Continuous Cycles : This mode is used where high production is
suggested.
Working of Hydraulic Press Brake:
- These Hydraulic presses are designed to adjust status of upper
cross-beams
- At time of pressing pedal/button, two-handed control yoke begins its
movement down to certain speed
- The speed of yoke movement is higher than speed of direct bending
process
- Reaching point of switching speeds, system control shifts to lower
speed (called working speed)
- After change of speeds, there is further movement that traverses to
bottom dead center, reaching bottom dead center occurs extract under
pressure
- This is time required for distribution to entire length of work piece
as this factor affects quality of manufactured products
- After end of time, cross-arm rises up to required size at slower
speed called decompression. After this stage, yoke reaches top dead
center
- The machine again comes in motion after there is another push to the
pedal/button control with the whole process starting once again
