Usage Procedure

To use the Schiavi STPC 204 folding machine:

1. Preparation : Make sure the machine is installed on a solid, level base. Ensure the hydraulic system and CNC are properly connected and functioning.
2. Loading the Piece : Place the piece of sheet metal 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 Workpiece : Once the bend is complete, remove the workpiece from the bench and check the quality of the bend.

Matching accessories

• Measuring and Control Tools : To check the precision of bends.
• Locking Accessories : To hold the pieces in place during bending.
• Automation Systems : To improve efficiency and productivity.

Mathematical Formulas for Optimal Use Parameters

To calculate the optimal usage parameters of the folding 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 part, 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 : Ensure that the machine does not exceed the maximum capacity of 200 tons to avoid damage and ensure safety.

Workable Materials

The Schiavi STPC 204 press brake is designed to process a wide range of metals, including steel, aluminum, and light alloys. It is suitable for sheet metal of various thicknesses and lengths, compatible with a 200-ton capacity.

Maintenance

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

• Hydraulic Check : Inspect and replace hydraulic fluids and check for leaks.
• Lubrication : Keep moving parts well lubricated to reduce wear.
• CNC Verification : Checks the CNC system to ensure that the programs and parameters are correct and working.
• Cleaning : Regularly remove material residue and dust from the table and blades.

Evaluation of a Good Used Car

To evaluate whether a used Schiavi STPC 204 folding machine is of good quality:

• External Conditions : Check the housing, blades and cylinders for signs of wear and damage.
