Cutting Tool Pressing Foot Assembly for Corrugated Sheet Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools face challenges in cutting corrugated sheets with numerous short fibers, as they either tear due to insufficient swinging amplitude or reduce cutting speed, and struggle to maintain precision when cutting solid sheets due to inadequate pressing and air communication issues.
Innovation Solution
A cutting tool design featuring a pipe, pressing foot assembly, spring, and blade assembly that allows for maximum cutting speed without motor-driven swinging, utilizing a spring for consistent pressing and magnetic members for easy adapter ring combination, enabling efficient cutting of corrugated and solid sheets by collapsing wave-shaped core layers and preventing through holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the swinging amplitude of the conventional cutting tool is increased to improve cutting effect on corrugated sheets with numerous short fibers, then the cutting precision is improved, but the cutting speed is reduced
Solution Approach 1:
Instead of swinging the cutting tool up and down to achieve cutting effect, the invention inverts the approach by keeping the blade stationary in the vertical direction and moving the pressing foot assembly to apply pressure to the corrugated sheet, allowing the blade to cut through the pressed material without vertical swinging motion
Solution Approach 2:
The invention replaces the motor-driven swinging mechanical system with a pressing mechanism that applies vertical force through the pressing foot assembly, substituting the oscillating cutting action with a continuous pressing and cutting action that eliminates the need for swinging amplitude adjustment
2Productivity
If the swinging amplitude of the conventional cutting tool is decreased to increase cutting speed, then the cutting speed is improved, but the cutting effect deteriorates
Solution Approach 1:
The invention inverts the conventional approach by eliminating vertical swinging motion entirely and instead using a pressing foot assembly to apply continuous vertical pressure to the material, allowing high-speed horizontal movement without compromising cutting quality
Solution Approach 2:
The motor-driven swinging mechanism is replaced with a pressing mechanism that maintains constant contact pressure on the corrugated sheet or solid sheet, enabling high-speed cutting without the need for amplitude modulation
3Productivity
If the conventional cutting tool moves horizontally along the cutting path, then the cutting speed is improved, but the solid sheet cannot be effectively pressed, causing through holes and cutting imprecision
Solution Approach 1:
The invention merges the pressing function and cutting function into a single integrated assembly where the pressing foot assembly and blade work together simultaneously, allowing the solid sheet to be continuously pressed and cut during horizontal movement without separation of these functions
Solution Approach 2:
The pressing foot assembly maintains continuous pressing action on the solid sheet throughout the entire cutting process, eliminating the intermittent pressing and releasing motion of conventional tools, which ensures consistent contact and prevents through holes while enabling high-speed continuous cutting

AI summary
A cutting tool includes a pipe, a pressing foot assembly, a spring, and a blade assembly. The pressing foot assembly is slidably sheathed on an end of the pipe. The spring is sheathed on the pipe. An end of the spring abuts against the pipe, and the other end of the spring abuts against the pressing foot assembly. The blade assembly passes through the pipe and the pressing foot assembly in a slidable manner. When the cutting tool moves along a first direction, the pressing foot assembly keeps pressing against an object in a second direction substantially perpendicular to the first direction, such that the blade assembly protrudes from the pressing foot assembly and cuts the object along the first direction.
