Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool heads for edge machining require complex and costly replacement and readjustment for different machining steps, with hydraulic and pneumatic systems being technically complex and space-intensive.
Innovation Solution
A tool head with a pressure switching mechanism that allows for simple and rapid switching between two sets of blades using a compact mechanism, enabling axial movement and automatic locking, eliminating the need for additional installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hydraulic and pneumatic systems are used for blade adjustment and fixing, then the tool head can switch between different blade sets, but the system becomes technically complex and requires additional installation space
Solution Approach 1:
The patent extracts and eliminates the complex hydraulic and pneumatic systems from the tool head, replacing them with a simplified mechanical pressure switching mechanism that uses only a spring and lever assembly, thereby removing unnecessary complexity while preserving blade switching functionality
Solution Approach 2:
The spring-loaded mechanism provides automatic blade section retraction and positioning without requiring external hydraulic or pneumatic power sources. The spring automatically returns the second blade section to its retracted position after machining, and the lever mechanism automatically engages/disengages blade sections based on pressure application, making the system self-sufficient
2Adaptability or versatility
If hydraulic and pneumatic systems are used for blade adjustment and fixing, then the tool head can switch between different blade sets, but additional installation space is required
Solution Approach 1:
The second blade section is nested within the tool head body in a retracted position, allowing it to be stored compactly when not in use. The spring-loaded mechanism and lever assembly are integrated into the existing tool head structure, eliminating the need for separate hydraulic or pneumatic component housings and reducing overall installation space
Solution Approach 2:
The patent merges the blade switching, fixing, and retracting functions into a single integrated spring-loaded lever mechanism, combining multiple functions that would traditionally require separate hydraulic and pneumatic systems into one compact mechanical assembly
3Manufacturing precision
If individual tool heads are used for different edge machining steps, then each machining operation can be optimized, but replacement and readjustment become costly and time-consuming
Solution Approach 1:
The tool head is designed with dynamic blade section positioning, allowing the second blade section to be rapidly extended or retracted based on machining requirements. This dynamic configuration enables a single tool head to perform multiple different edge machining operations by simply switching which blade section is active, eliminating the need for physical tool head replacement between operations

AI summary
A tool head is for machining edges of a workpiece and includes a first tool section with first blades and a second tool section with second blades. The second blades are positioned between the first blades when seen in the circumferential direction. The second section is movable relative to the first section in the direction of the longitudinal axis between a passive and active position. The second blades are axially recessed relative to the first blades in the passive position and project axially outwards between the first blades in the active position. The tool head has a pressure switching mechanism for moving the second tool section between the passive and active position. In a tool system, the tool head and an actuation element can be moved axially relative to each other. The at least one actuation surface and the actuation element are configured to be axially pressed towards each other.
