Usage Procedure

To use the Schiavi STPC 204 bending machine:

1. Preparation : Check that the machine is installed on a solid and level base. Make sure the hydraulic system and CNC are properly connected and working.
2. Loading the Piece : Place the sheet metal piece on the workbench, aligning it with the guides.
3. Programming : Use the Promecam DBM CNC to set bending parameters, such as bend angle and length.
4. Execution : Starts the bending cycle. The hydraulic cylinders will apply the necessary force to bend the material according to the set specifications.
5. Removing the Piece : Once bending is complete, remove the piece from the bench and check the quality of the bend.

Matching accessories

• Measurement and Control Instruments : To check the precision of bends.
• Clamping Accessories : To hold pieces in place during bending.
• Automation Systems : To improve efficiency and productivity.

Mathematical Formulas for Optimal Use Parameters

To calculate the optimal use parameters of the bending machine:

• Force Required for Bending : F=L⋅t2⋅σKF = \frac{L \cdot t^2 \cdot \sigma}{K} $F$ $=$ K L ⋅ t 2 ⋅ σ

  • Where FF $F$ is the required force, LL $L$ is the length of the workpiece, tt $t$ is the thickness of the material, σ\sigma $\sigma$ is the tensile strength of the material, and KK $K$ is a correction factor.

• Bending Capacity : Check that the machine does not exceed the maximum capacity of 200 tons to avoid damage and ensure safety.

Workable Materials

The Schiavi STPC 204 bending machine is designed to process a wide range of metallic materials, including steels, aluminum and light alloys. It is suitable for sheets of different thicknesses and lengths, compatible with the capacity of 200 tons.

Maintenance

To ensure long life and optimal operation of the Schiavi STPC 204 bending machine:
