Solution Overview
Problem
Current machine tools are inefficient for performing both machining and bending operations on workpieces, requiring multiple iterations and relocation between machines, which increases manufacturing time and complexity.
Innovation Solution
A machine tool with a numerically controlled turning or milling capability, incorporating a linear movable tool carrier slide and integrated bending tools, allowing for simultaneous and efficient machining and bending operations by rotating and moving working units around a B-axis and in the X-Z plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate machine tools are used for machining and bending operations, then each machine can be optimized for its specific function, but production time increases and manufacturing complexity increases due to relocation between machines
Solution Approach 1:
The patent combines machining tools (milling head, turning tools) and bending tools (press brake mechanism) into a single integrated machine tool system. The working unit can be configured with both machining spindles and bending actuators, allowing multiple operations to be performed without relocating the workpiece between separate machines.
Solution Approach 2:
The machine tool is designed with universal working units that can perform multiple functions. The tool carrier can hold both machining tools and bending tools, and the control system can switch between different operation modes (machining, bending, or combined operations) on the same workpiece throughout the manufacturing process.
2Reliability
If multiple separate machines are used for complex products requiring both bending and machining steps, then each operation can be performed with dedicated equipment, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent integrates multiple functional systems (machining spindles, bending press brake mechanism, tool carriers) into a single coordinated machine tool. The control system manages the coordination between different working units, reducing the need for multiple separate machines and simplifying the overall manufacturing setup.
Solution Approach 2:
The machine tool is divided into modular working units that can be independently configured and controlled. Each working unit can be equipped with specific machining or bending tools as needed, allowing flexible configuration while maintaining system integration. This modular approach reduces complexity by allowing selective activation of only the required functions for each workpiece.
3Reliability
If workpiece relocation between machine tool and bending machine is required, then specialized equipment can be used for each operation, but manufacturing efficiency decreases and production time increases
Solution Approach 1:
The patent combines machining and bending capabilities in a single machine tool, eliminating the need to relocate workpieces between separate machines. The integrated system allows continuous processing of workpieces through multiple operations without interruption for transportation or repositioning between different equipment.
Solution Approach 2:
The machine tool enables continuous processing by maintaining the workpiece in the same location throughout multiple operations. The control system coordinates machining and bending operations sequentially or simultaneously on the same workpiece, ensuring uninterrupted manufacturing flow and eliminating downtime associated with workpiece relocation.
