Project Description

Sheet metal bending is a widely used manufacturing process in industries such as automobile, construction, fabrication, and product manufacturing. Conventional industrial bending machines are often expensive and unsuitable for small workshops, educational laboratories, and low-volume production requirements. The Portable Manual Sheet Metal Bending Machine provides an economical solution by enabling accurate bending operations through a simple mechanical arrangement. The system consists of a sturdy mild steel fabricated frame, bending rollers, adjustable guides, clamping arrangement, and a manually operated lever mechanism. The operator places the sheet between the bending elements and applies force through the lever, creating controlled deformation at the required angle. The adjustable bending mechanism allows users to achieve different bend angles based on project or manufacturing requirements. The compact design improves portability and reduces space requirements compared to large industrial machines. This project helps students understand sheet metal forming principles, mechanical force transmission, structural design, fabrication techniques, and manufacturing process optimization. The machine is suitable for prototype development, engineering workshops, and educational demonstrations where affordable and reliable metal forming equipment is required. By combining simplicity, low fabrication cost, and practical functionality, the project demonstrates how mechanical design principles can be applied to create useful manufacturing tools for small-scale applications.
