Solution Overview
Problem
Existing automatic bending machines are limited in their ability to bend products with varying lengths and asymmetrical shapes, as they lack flexibility in tool length adjustment and accurate positioning, leading to inefficiencies and production challenges.
Innovation Solution
A fully automatic bending machine is designed with an electric servo bending center cutter driving mechanism, an automatic tool changer, and a positioning and clamping workbench that includes a feeding rotary manipulator, enabling flexible tool length adjustment and precise positioning for both symmetrical and asymmetrical shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single symmetrical positioning mechanism is used, then the structure is simple, but it cannot position asymmetrical plates accurately
Solution Approach 1:
The positioning mechanism is divided into left and right independent positioning devices, each capable of being adjusted independently. This segmentation allows the system to handle both symmetrical and asymmetrical plates by adjusting each side according to the specific plate geometry, resolving the contradiction between structural simplicity and positioning versatility.
Solution Approach 2:
The positioning mechanism incorporates adjustable components that can be dynamically reconfigured for different plate shapes. The left and right positioning devices can be independently adjusted to accommodate various asymmetrical configurations, enabling the system to adapt to different positioning requirements while maintaining a relatively simple base structure.
2Productivity
If the bending tool length is fixed at maximum folding length, then the machine can handle long plates, but it cannot bend products with varying lengths efficiently
Solution Approach 1:
The bending tool is designed with adjustable length capability, allowing it to be dynamically reconfigured for different product lengths. This dynamic adjustment feature enables the machine to efficiently handle products with varying lengths by optimizing the tool length for each specific task, improving productivity without requiring a completely complex adjustment mechanism.
Solution Approach 2:
The bending tool is designed to perform multiple functions by adjusting its length. A single tool can handle both long plates and shorter products with varying lengths, eliminating the need for multiple specialized tools and improving overall productivity while maintaining reasonable device complexity.
3Ease of operation
If a large contact surface between table top and plate is used, then the plate is stable, but it is inconvenient to move the plate on the table surface
Solution Approach 1:
The table top is divided into multiple segmented support surfaces rather than a single large continuous surface. This segmentation reduces the contact area between the table top and the plate, making it easier to move the plate on the table surface while still providing adequate stability during positioning through strategically placed support points.
4Productivity
If manual positioning and tool changes are used, then the device structure is simple, but labor costs are high and production efficiency is low
Solution Approach 1:
The system incorporates an automatic tool changer that enables the bending machine to automatically change tools without manual intervention. This self-service capability eliminates the need for operators to manually change tools, significantly reducing labor costs and improving production efficiency while the added automation complexity is offset by the elimination of manual operations.
Solution Approach 2:
The positioning system is designed to automatically position plates before bending operations begin. This preliminary automatic positioning action eliminates the need for manual positioning, reducing labor requirements and improving production efficiency. The automation is integrated in such a way that the initial complexity is justified by the ongoing productivity gains.
