Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radial presses, particularly high-precision and high-performance ones, incur significant financial burdens for smaller facilities due to high costs, and there is a need to enhance their economic efficiency and service life.
Innovation Solution
Incorporating linear guide elements in the cutting tool of a radial press to guide base structures towards each other, allowing for internal force flow and reducing transverse forces, and optimizing cutting attachments for specific tasks with interchangeable designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a radial press is equipped with cutting attachments to perform cutting tasks, then productivity and versatility are improved, but asymmetrical transverse forces act on the base jaws during cutting, reducing reliability and service life
Solution Approach 1:
The patent introduces asymmetrical guide elements that are specifically designed to counterbalance the asymmetrical transverse forces generated during cutting. These guide elements create symmetrical reaction forces that compensate for the inherent asymmetry in cutting force distribution, thereby protecting the base jaws from damaging asymmetrical loads while maintaining cutting functionality
Solution Approach 2:
The guide elements act as intermediary components between the cutting attachments and the base jaws. They mediate the force transmission by guiding the cutting attachments and converting asymmetrical cutting forces into symmetrical reaction forces, preventing direct transmission of harmful asymmetrical loads to the base jaws
2Manufacturing precision
If high-precision radial presses are used to achieve accurate pressing, then manufacturing precision is improved, but investment costs increase significantly, worsening economic efficiency for smaller facilities
Solution Approach 1:
The patent makes the radial press universal by enabling it to perform both pressing and cutting functions using the same base jaw structure. The cutting attachments can be mounted on existing base jaws, allowing a single machine to handle multiple operations, thereby eliminating the need for separate dedicated cutting machines and improving economic efficiency
3Ease of manufacture
If dedicated cutting machines are avoided to reduce investment costs, then economic efficiency is improved, but the radial press must handle cutting tasks without proper guidance, worsening reliability
Solution Approach 1:
The patent segments the cutting tool into modular components: cutting attachments that can be mounted on base jaws, with integrated guide elements. This segmentation allows the cutting function to be added to the radial press without requiring a complete dedicated cutting machine, maintaining reliability through proper guidance while avoiding excessive investment

AI summary
The invention relates to a radial press comprising at least six main jaws (8) which are arranged concentrically and in a uniform manner about a press axis (X) and can be moved radially in the direction of the press axis (X) and away therefrom by means of a drive unit and each of which has a contact surface (9) radially inwards as well as mechanical holding means for press jaws that can be attached to the main jaws in an exchangeable manner. According to the invention, a cutting tool (11) is received in a tool installation area delimited outwardly by the main jaws (8). The cutting tool comprises multiple cutting attachments (12), each of which is attached to a main jaw (8) and each of which comprises a base structure (13). At least one of the cutting attachments (12) additionally comprises a cutting structure (14). Each base structure (13) has a support surface which rests against the contact surface (9) of the paired main jaw (8) and at least one engagement element which interacts with the mechanical holding means of the paired main jaw (8). The at least one cutting structure (14) protrudes from the paired base structure (13) in the direction of the press axis (X) and has a cutting edge facing away from the support surface of the paired base structure (13).
