FEA & Stress Analysis of Small Press Brake
Stress Analysis & Finite Element Analysis
CAMT evaluate its structural integrity, performance, and efficiency under operational loads. The analysis focuses on key components, including the frame, bending arm, and drive system, modeled using 3D finite element methods. Material properties, such as steel for the frame and high-strength alloys for moving parts, are defined to ensure accuracy. Boundary conditions simulate real-world loading scenarios, including maximum bending forces and torque from the electric motor. The FEA assesses stress distribution, deformation, and fatigue life to identify potential failure points. Results indicate that the machine’s design meets safety and performance requirements, with optimized stiffness and minimal deflection under load. Recommendations for improving structural efficiency and reducing material usage are provided based on the analysis. This study demonstrates the effectiveness of FEA in enhancing the design and reliability of pure electric bending machines.

VICHI Servo Drive Theory
Servo Pure Press Brake Direcly Drive-Structure &Principle
Advantages:
The innovative design of a direct-connected all-electric servo press brake integrates a servo motor, reducer, and heavy-duty lead screw in a streamlined configuration, eliminating the synchronous pulley mechanism. This approach resolves issues associated with synchronous pulley systems, such as high noise levels and safety concerns due to belt breakage. The new design offers low noise, minimal repeat positioning error, a simple and reliable structure, and reduced costs.
In this system, the servo motor directly drives the reducer and lead screw, enabling rotational motion. The lead screw nut, driven by the screw’s rotation, moves vertically, actuating the slider. The slider, in turn, drives the upper mold to perform vertical movements, facilitating precise sheet metal bending. This direct-connection mechanism enhances operational efficiency, reliability, and precision while maintaining a cost-effective and compact design, making it an ideal solution for modern sheet metal processing.
Direct-Connect Design
Direct-Connected Main Motor, Reducer, and Lead Screw
- Compared to synchronous belt systems, the direct-connected design is easier to assemble and more reliable
- Unlike synchronous belt systems, the direct-connected configuration eliminates the risk of belt breakage, which can lead to uncontrolled slider movement and braking issues.
- Generates significantly less noise than traditional synchronous belt transmission
- superior accuracy without requiring a magnetic scale for closed-loop control, reducing costs
- his feature counteracts the slider’s gravity, eliminating the need for a brake motor in the servo system, further lowering costs
- The main spindle servo motor operates at 4000 RPM, enabling faster performance
- he servo motor is equipped with an absolute encoder, eliminating the need to search for the zero position upon startup
Pure Electric Press Brake Following Major Advantages
- The servo-driven system consumes power proportional to the load, significantly reducing energy usage. Minimal power is consumed when the slider is idle, unlike hydraulic machines that continuously draw power. The main transmission efficiency exceeds 95%, compared to less than 80% for hydraulic systems, with hydraulic efficiency further declining due to aging and wear.
- Eliminating hydraulic oil removes the need for oil changes, hydraulic component maintenance, and handling daily oil leaks. This reduces waste oil disposal and pollution. High slider speeds and production efficiency further contribute to eco-friendly operations.
- Adjustable bending speeds allow precise control for varying material thicknesses, types, and bending lengths, ensuring high accuracy (±0.5° angle error) compared to hydraulic machines (±1° error). The direct-drive system enhances transmission precision without requiring costly closed-loop systems
- Unlike hydraulic systems, which require regular oil changes and are prone to pump, valve, and seal failures, pure electric bending machines feature a simple transmission system with minimal maintenance needs, typically limited to periodic lubrication
