Swing Beam Metal Shearing Machine with Bosch-Rexroth Hydraulic Valves​

Main structure of the machine

Frame

The combination welding monolithic construction is adopted for the machine frame, so it has the good rigidity. The two oil cylinders are fixed on the left and right wallboards, the auxiliary knife seat which is used to fine adjust the bottom blade is equipped on the working table. The feeding rolling balls are fixed on the working table to make the plate feeding easy.

Top knife carrier

The top knife carrier is welded case-type structure, it has good rigidity. It finishes the shearing under the control of the oil cylinders.

Plate pressing device

The pressing oil cylinders which are fixed on the supporting plate compose the pressing device. The cylinders will press the plate when the pressure oil flows into the cylinder, and they will return to the original position through the spring after the shearing.

Front and back gauge

The front gauge is fixed on the working table, especially used for the thick plate shearing. The back gauge is fixed on the top knife carrier and moves with the top knife carrier together.

Hydraulic system of the machine

This system includes the axial-plunger pump and the cartridge inserted valve integrated system. The pressure oil for the machine is supplied by the axial-plunger pump, and the max working pressure is 24MPa, the return stroke is finished through the oil cylinders. Within the accumulator nitrogen inflator, inflation pressure is 6 ~ 8 MPa.

Electrical system of the machine

The electrical system of the machine is 3-phase ac 380V,50HZ power supply. The control circuit power and the aligning lamp power are provided through the control transformer. The hydraulic solenoid valve power is 24V which is provided through the control transformer after step-down .

The machine has two motors include the oil pump motor and the back gauge motor

The machine has several working modes. Operation is easy. Electric component is Siemens, Shanghai Electric Component Company or Beijing Low-voltage Switch Company

Feature of the machine

The working table and the knife beam are all welded steel plate structure. And process the aging treatment after welding to ensure the high accuracy.

Series connected cylinders structure with good synchronism, and the shearing angel can be adjusted, so the realize the high cutting quality.

Three points support the guide rail of the upper blade frame to get high shearing accuracy, and the blade clearance can be adjusted quickly.

The blade stroke can be adjusted to increase the working efficiency.

The upper knife beam adopts the inward tiling structure for easy blanking and increase the workpiece quality. Overall rectangular blade , four edges can be used.

Digital displaying backgauge ,which is easy to be adjusted . Digital system is NC89 and easy to control

The motor of back gauge has three adjustment include the forward, backward, and manual micro adjustment.

The inter lock device is used for human safety.
