Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional hydraulic press equipment is used for automobile hub production, then the equipment can perform pressing operations, but the equipment becomes heavy and expensive
Solution Approach 1:
The hydraulic press equipment is divided into modular components including multiple main cylinder devices, support assemblies with sliding rails, and worktable assemblies. Each module can be independently configured and combined, allowing the system to achieve high productivity through parallel processing of multiple workpieces while maintaining reduced weight through optimized component selection and arrangement.
2Ease of manufacture
If traditional hydraulic press equipment is used, then pressing operations can be performed, but the equipment becomes complicated in manufacturing
Solution Approach 1:
The support assembly with sliding rails and the main cylinder devices are designed as universal components that can be applied across different pressing configurations and worktable arrangements. The standardized interface and modular design enable these components to serve multiple functions in various production scenarios, significantly reducing manufacturing complexity while maintaining equipment capability.
3Productivity
If traditional hydraulic press equipment is used, then single workpiece pressing can be achieved, but production efficiency remains low
Solution Approach 1:
Multiple main cylinder devices are combined with a single support assembly and worktable system, enabling simultaneous pressing of multiple workpieces in parallel. The sliding rail mechanism coordinates the movement of multiple cylinders, achieving high production efficiency through synchronized operation while managing overall system complexity through integrated control and standardized component interfaces.

AI summary
The present disclosure discloses a main cylinder device including a main cylinder assembly (31) and a plurality of piston rods (32) connected with the main cylinder assembly (31). The number of the plurality of piston rods (32) is at least two or two sets, a hydraulic chamber is formed between the plurality of piston rods (32) and the main cylinder assembly (31). The at least two or two sets of piston rods (32) are arranged opposite to each other and move along a same straight line. When the main cylinder device is working, the hydraulic chamber has a spatial change, causing the at least two or two sets of piston rods (32) to approach each other or move away from each other. Because two or two sets of piston rods (32) are arranged opposite to each other and move along opposite directions during pressing operation, it can effectively keep pressure balance of the piston rods, and the reaction forces between the piston rods 32 can also be cancelled, improving consistency of work pieces.
