Q11K-16×4000(NC89)
CNC Hydraulic Guillotine Shears


.Performance and application
 The max plate thickness is 14mm and the max  plate width should be ≤6000mm, The machine is welded steel plate structure and hydraulic driving, the knife beam returning is realized through the accumulators  and returning cylinders. The machine is stable in operation, small in size, light in weight and good in rigidity
   The machine is equipped with the blade clearance adjustment device and the reading tablet, so the blade clearance adjustment is easy and the readings are accurate. The front and back gauge, the safety fence are equipped with the machine, as well as shearing times counting device.
. Technological process of the machine
1. Shot blast for the cleaning of the plate  
  The shot blast cleaning has the following advantages:

1. Increase the resistance to corrosion for the metal plate
2. Increase the fatigue resistance of the plate and extend the working period.
3. Optimize the technique  state of the plate surface
4. In favor of the blanking of the CNC cutting machine
5. The rust removal and the coating are easy for the plate shape is regular before to be machined.

2 .CNC cutting blanking for plate
3 .Planning and milling the plate parts.
4. Aging treatment to remove the inner stress happened during the welding
5. Machining after the welding part annealing
6. Assembly, trial run, trail shear, spray-paint
.Main structure of the machine
1.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.
2. Top knife carrier
The top knife carrier is welded case-type structure, it has good rigidity. The blade clearance can be adjusted quickly. It finishes the shearing under the control of the oil cylinders.
3. 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, the pressing force will be increased along the plate thickness increased.
  4. Front and back gauge
The front gauge is fixed on the working table . 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.
. Electrical system of the machine
1. Brief account
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 220V 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 include the inch and single operation. which is easy for the operator.
2. Electric Components are Siemens(Suzhou), Shanghai or Beijing products.
Electrical system
The electrical system is NC-89system.

. Feature of the machine
1. The machine frame and the knife beam are all welded steel plate structure. and process the annealing treatment after welding, so that ensure the high accuracy.
2. Series connected cylinders structure with good synchronism, and the shearing angel can be adjusted, so the realize the high cutting quality.
3.Three-point support the guide rail of the upper blade frame to get high shearing accuracy, and the blade clearance can be adjusted quickly.
4. The blade stroke can be adjusted steplessly to increase the working efficiency.
5. The upper knife beam adopts the inward tiling structure for easy blanking and increase the workpiece quality.
6. Overall rectangular blade , four edges can be used, so the operation life is long.
7. The operation mode includes the inch and single operation.
8.. The electromechanical interlocking device is used for human safety.
