Powder Press Hydraulic Piston Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder presses have a large construction footprint due to the space required for pistons and cylinders, which limits their compactness and accessibility within the tension elements.
Innovation Solution
The powder press design features pistons or cylinders that surround a passage opening through the die accommodation plate or yoke, allowing for a more compact structure by eliminating the need for separate modules and enabling easier maintenance and control of the punch units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If pistons and cylinders are arranged in traditional separate modules, then the powder press can accommodate the necessary hydraulic components, but the construction footprint becomes large and compactness is reduced
Solution Approach 1:
The patent merges the piston and cylinder into an integrated unit where the piston surrounds a passage opening through the die accommodation plate or yoke. This integration eliminates the need for separate modules and reduces the overall construction footprint while maintaining hydraulic functionality.
Solution Approach 2:
The piston is nested within the cylinder structure, with the piston surrounding a passage opening. This nested arrangement allows the hydraulic components to occupy less space while maintaining their functional integrity, thereby reducing the construction footprint.
2Ease of operation
If traditional separate modules are used for pistons and cylinders, then hydraulic functionality is maintained, but accessibility for maintenance and control is reduced
Solution Approach 1:
By merging the piston and cylinder into an integrated unit with the piston surrounding a passage opening, the design improves accessibility for maintenance and control. The integrated structure eliminates multiple separate modules that would require disassembly, allowing easier access to hydraulic components.
3Object-affected harmful factors
If the cylinder opens toward the bottom, then powder accumulation is minimized, but the cylinder requires additional space for hydraulic fluid and sealing
Solution Approach 1:
The cylinder is oriented to open toward the bottom rather than the top, inverting the conventional arrangement. This inversion minimizes powder accumulation in the gap between cylinder and piston while the compact integrated design reduces the overall space requirement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration results in a significantly more compact powder press with reduced risk of powder accumulation and improved accessibility, while allowing for uniform force application and efficient hydraulic guidance, minimizing the risk of tilting and powder collection.
Implementation Method 1
the punch comprises at least a cylinder and/or a piston disposed in the cylinder, to which hydraulic pressure can be applied in the cylinder

AI summary
A powder press has an upper yoke, a lower yoke, and a tension element that is in effect between the upper yoke and the lower yoke, as well as a die accommodation plate that is guided along the tension elements. The plate can be displaced parallel to the tension element, via a punch that supports itself on the upper yoke or the lower yoke, or to which pressure can be applied. The punch accommodates a die plate provided on an adapter and includes at least a cylinder and/or a piston disposed in the cylinder, to which hydraulic pressure can be applied in the cylinder. The powder press has a particularly compact construction if the cylinder and/or the piston surrounds a passage opening through the die accommodation plate or through the upper or lower yoke and/or a tension element.
