Workpiece Cutting Tool With Detachable Edge Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools require the cutting edge to be displaced back through the workpiece after cutting, which can be difficult in confined spaces and inefficient, especially in civil engineering applications.
Innovation Solution
The cutting edge can be moved out of the cutting direction by being removed from the advancement part after passing through the workpiece, allowing it to assume a position that facilitates easy removal, and a clearance is maintained between the cutting edge and the receiving contour through a backward displacement of the receiving contour, enabling easier handling and reduced need for retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cutting edge is displaced back through the workpiece after cutting, then the tool can be reset for the next cut, but this is difficult in confined spaces and inefficient
Solution Approach 1:
The tool is divided into separable components: the cutting edge can be detached from the tool body after cutting, allowing independent removal of the cutting edge while the tool body remains in position. This segmentation enables easy removal without retracting the entire tool through the workpiece.
Solution Approach 2:
The cutting edge is extracted or removed from the tool body after the cutting operation is complete. This extraction allows the cutting edge to be taken out from the confined space without requiring the entire tool to be retracted, solving the problem of difficult removal in confined spaces.
2Productivity
If the cutting edge passes completely through the workpiece, then the workpiece is fully severed, but the cutting edge must then be retracted which is complex in difficult-to-access areas
Solution Approach 1:
The cutting system is segmented into the cutting edge and the tool body, allowing the cutting edge to complete its full traversal through the workpiece for complete severing, while the tool body remains stationary. This segmentation simplifies the overall process by eliminating the need to retract the entire tool.
Solution Approach 2:
Instead of retracting the cutting edge back through the workpiece (the conventional approach), the invention inverts the approach by leaving the cutting edge in place and removing it from the tool body. This inversion eliminates the complex retraction motion through the workpiece.
3Reliability
If the cutting edge maintains contact with the receiving contour throughout the cutting process, then the workpiece is securely held, but removal becomes difficult after cutting
Solution Approach 1:
The system is segmented into the cutting edge and the receiving contour structure. During cutting, the cutting edge maintains contact with the receiving contour for secure holding. After cutting, the cutting edge can be detached from the tool body and removed independently, while the receiving contour remains in place, facilitating easy removal after the cutting function is complete.

AI summary
A tool configured to cut a workpiece includes a tool head which has a receiving contour in which the workpiece is received, and a movable cutting edge with a cutting contour. In the course of a cutting process, the cutting edge passes through the receiving contour. The cutting edge is subjected to the effect of an advancement part and can be moved to such an extent in the cutting direction(s) that it can pass all the way through the workpiece. In an embodiment, a position of the cutting edge reached after the cutting edge has passed all the way through the workpiece, the cutting edge, with removal from the advancement part, can be moved out from the cutting direction(s).
