Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combined cold isostatic press and general press systems are costly, complex, and difficult to maintain due to separate apparatuses for die pressing and cold isostatic pressing, requiring multiple pressure media and hydraulic components, which complicates operations and increases manufacturing costs.
Innovation Solution
A combined system where a single pressure container functions for both cold isostatic pressing and general pressing, with a main frame supporting a pressure vessel that uses fluid pressure for isostatic pressing and a sliding top lid for general pressing, featuring a simplified structure with reduced hydraulic components and a unified working level for enhanced productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate apparatuses are used for die pressing and cold isostatic pressing, then each process can be performed independently, but manufacturing cost and installation area increase
Solution Approach 1:
The patent combines die pressing and cold isostatic pressing functions into a single integrated apparatus. The pressing unit serves dual purposes: it can perform die pressing when the main frame is aligned with it, and perform cold isostatic pressing when aligned with the cold isostatic press unit. This merging eliminates the need for separate apparatuses, reducing manufacturing cost and installation area while maintaining process functionality through a common single pressurizer that supplies pressure to both modes.
Solution Approach 2:
The pressing unit is designed with universal functionality to perform both die pressing and cold isostatic pressing operations. The main frame can be positioned to align with either the pressing unit or the cold isostatic press unit, allowing the same pressing unit to serve multiple pressing modes. The common single pressurizer also exhibits multi-functionality by providing pressure for both die pressing and cold isostatic pressing, reducing the need for duplicate hydraulic systems.
2Adaptability or versatility
If a main frame is moved between press unit and cold isostatic press unit, then both processes can be performed, but precision maintenance becomes difficult and time loss occurs
Solution Approach 1:
The system employs dynamic positioning of the main frame, which can be moved between different operational positions to align with either the pressing unit or the cold isostatic press unit. This dynamic configuration allows the apparatus to adapt between different pressing modes while maintaining precision through controlled movement mechanisms that ensure accurate alignment during position transitions.
3Adaptability or versatility
If both cold isostatic press unit and hydraulic cylinder are provided, then both CIP and die pressing can be performed, but manufacturing cost increases and hydraulic components multiply
Solution Approach 1:
The common single pressurizer is designed to provide hydraulic pressure for both die pressing and cold isostatic pressing operations. This universal pressure source eliminates the need for separate hydraulic systems for each pressing mode, reducing the total number of hydraulic components while maintaining full functionality for both pressing types. The pressurizer can supply pressure to the pressing unit for die pressing or to the cold isostatic press unit for CIP operations.
4Adaptability or versatility
If double staged pressing levels are adopted, then CIP and die pressing can be performed, but worker movement distance increases and transport device usage becomes difficult
Solution Approach 1:
The apparatus is designed with a unified working level that eliminates the need for double-staged pressing levels. Both die pressing and cold isostatic pressing operations can be performed at the same operational level, creating an equipotential working environment. This design reduces worker movement distance between different pressing levels and facilitates easier use of transport devices for moving dies and products, as all operations occur within the same horizontal plane.

AI summary
Provided is a combined cold isostatic press and general press capable of simultaneously performing cold isostatic pressing using pressure of fluid and general pressing using mechanically applied pressure. The combined cold isostatic press and general press includes a main frame having a center penetration region, a pressure vessel supported by the penetration region of the main frame, the pressure vessel performing cold isostatic pressing using fluid injected therein, a top lid installed to be vertically slidable from or to an upper end of the pressure vessel by the fluid filled in the pressure vessel so as to function as piston, the top lid being configured to open or close the upper end of the pressure vessel, a lower lid configured to open or close a lower end of the pressure vessel and a press unit located between the top lid and the main frame to perform pressing using pressure applied by the top lid as the top lid slides from the pressure vessel. As such, enhanced productivity and reduction in fluid consumption and manufacturing costs may be accomplished.
