Main Structure of Dafu’s Hydraulic Swing Beam Shearing Machine
1. Machine frame: Steel-welded plate, high rigidity. Two cylinders fix on left and right vertical pole of shearing machine. Installed vice cut-board on worktable conveniently adjust low-cut board. Keep the gap between up-cut and low-cut coincidence. Install feed ball on worktable, operation is convenient and fast.
2. Sheet metal cutting tool frame: welded plate, high rigidity, is support at eccentric socket, by left and right cylinders and stroke cylinder drive, finish cutting by pendulum repeat. The vertical surface of up-cut support is curve; keep the gap between up-cut and low-cut coincidence.
3. Pressure device: it is consisted of some pressure feed cylinders installed at support board in front of machine frame of hydraulic swing beam shearing machine. Oil flow in pressure feed cylinder, pressure head press down against the pull force of stress spring, press plate tightly. Finish cutting, the cylinders are reset by the pull force of stress spring. The pressure is bigger as thicker as the thickness of plate.
4. Front gauge and back gauge: Front gauge: fixed on worktable, valve display on ruler, adjust mobile bar to necessity valve. When cut thin steel plate, cut it conveniently on front gauge. Back gauge of hydraulic shear is fixed on up-cut board, pendulum up and down as up-cut board. Adjust back gauge by 0.55Kw motor, reduce through gear, and drive by control rod. Brake down the button “+” (or”_”), can adjust gauge to front or back. When mechanic adjustment cannot get the necessity valve, turn hand-wheel to demand valve, the adjustment of back gauge is convenient and reliability.
The standard range of back gauge is 20-750mm. When the length of cutting plate is longer than the max distance of back gauge, remove the back gauge to the least place, lift up the board by the incline surface of support frame, and can cut any length of plate.
