1. The frame adopts a fully welded steel structure with sufficient strength and rigidity, and internal stress is eliminated through normalizing and high-frequency vibration to ensure the overall accuracy of the fuselage.

2. Using a large German floor boring and milling machine, precision machining is carried out using a one-time processing method to ensure machining accuracy.

3. Hydraulic swing structure, upper knife holder return device, using nitrogen cylinder return, fast speed.

4. The hydraulic system adopts an integrated logic circuit, controlled by sequential valves, with smooth operation, low noise, and simple maintenance.

5. Using domestic hydraulic valves to control the operation of the tool holder.

6. The pressing device adopts an integral circuit and an independent parallel pressing cylinder. When the sheet metal is uneven, it can freely stretch and compress the sheet metal, and the pressing force can also be adjusted according to the material and thickness of the sheet metal, without damaging the surface of the board.

7. Adopting an eccentric wheel mechanism and manually adjusting the blade clearance through a dial, the operation is simple to adapt to the cutting needs of different plate thicknesses and materials.

8. Controlled by a time relay, fixed range cutting can be achieved.

9. The number of cuts is controlled by a counter.

10. Light line shadow matching device, convenient for marking and cutting.

11. The electric rear material blocking device has manual adjustment and numerical display functions.

12. The electrical control is centralized and reliable, as follows:

The power facilities are all located inside the fuselage and can be controlled and implemented through buttons on the control panel.

Equipped with a foot switch, the cutting action can be directly operated through it, which is convenient and fast.

The main electrical components are selected from Shanghai Chint products.
