Forging Press External Closing Apparatus Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forging presses for rotationally asymmetrical parts have complex and expensive tool structures, limiting automatic part transfer, manipulator usage, and leading to rapid wear and leaks due to heat introduction, while restricting tool replacement and requiring complex peripheral systems.
Innovation Solution
A forging press design with a stationary press table and vertically shiftable press ram, where closing apparatuses are positioned outside the working space, allowing for a simpler and robust tool structure, increased space for manipulators, and separate force generation, enabling adaptable closing forces and easier tool replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If closing apparatuses are positioned inside the working space, then closing force can be applied directly to the dies, but the tool structure becomes complex and expensive, and space for manipulators is reduced
Solution Approach 1:
The closing apparatuses are extracted from the working space and positioned outside it. The first closing apparatus is positioned below the press table, and the second closing apparatus is positioned above the press ram, both outside the working space. This extraction eliminates the conflict between closing apparatuses and tool components while maintaining the necessary closing force application through extended force transmission members.
2Force
If closing apparatuses are positioned inside the working space, then closing force can be applied directly, but collisions between closing apparatuses and manipulators or tools may occur
Solution Approach 1:
The closing apparatuses are positioned outside the working space to eliminate collision risks. The first closing apparatus is located below the press table and the second above the press ram, ensuring that manipulators and tool components can move freely within the working space without risk of collision with the closing apparatuses.
Solution Approach 2:
Extended force transmission members (such as extended lower tool portions or extended upper part portions) act as intermediaries to transmit the closing force from the externally positioned closing apparatuses to the dies within the working space, allowing force application without physical presence in the collision-prone area.
3Force
If closing apparatuses are positioned inside the working space, then closing force can be applied directly, but heat from the forging process causes rapid wear of seals
Solution Approach 1:
The closing apparatuses are extracted from the working space to the external regions (below the press table and above the press ram), removing them from the high-temperature environment generated by the forging process. This thermal separation protects seals and other sensitive components from heat-induced wear and extends their service life.
4Force
If complex tool structures with multiple individual parts are used, then closing force can be applied, but automatic forged part transfer and manipulator usage are prevented
Solution Approach 1:
The closing apparatuses are extracted from the working space, simplifying the tool structure within the working space and removing obstacles to automatic part transfer and manipulator usage. The external positioning of closing apparatuses allows standard manipulators to operate freely within the working space for spray application, part transfer, and other auxiliary operations.

AI summary
A forging press for rotationally asymmetrical parts by warm or hot forming has a stationary press table, a vertically shiftable press ram above the press table, vertically delimiting with the press table a working space, and vertically displaceable between from an upper open position into a lower closed position. An upper part is carried by the ram in the space, and an upper die in the space is in turn carried on the upper part. A lower part sits on the table in the space and below the upper part and carries a lower die in the space and fittable with the upper die in the closed position. A first closing apparatus outside the space bears vertically on one of the dies, and a second closing apparatus outside the space bears vertically via the first closing apparatus on the one die.
