Sliding Platen Cutting Assembly for Accurate Fragile Workpiece Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices face challenges in maintaining cutting accuracy and quality due to height and speed differences between platens, leading to poor cutting results and increased labor input when handling fragile workpieces.
Innovation Solution
A cutting device with a slidably connected platen that has a longer slide stroke than the cutting stroke, equipped with a drive assembly, power supply, and adjustable components to ensure precise cutting and reduce manual support requirements, featuring a slide assembly with a track and sliding sleeve for enhanced movement accuracy and a lock assembly for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two platens are fixed separately to support the workpiece, then the workpiece does not need manual support, but the platens may differ in height and speed due to mounting errors, affecting cutting accuracy
Solution Approach 1:
The patent merges the two separate platens into a single integrated platen structure with a unified base. This single platen includes a first platform for supporting the workpiece and a second platform for supporting the cut piece, connected through a through-hole. By combining the support functions into one rigid structure, the patent eliminates height and speed differences between separate platens, ensuring cutting accuracy while still providing automatic support for both the workpiece and cut piece without manual intervention.
2Manufacturing precision
If the platen movement distance is set to match the cutting dimension, then cutting requirements are met, but movement errors may cause insufficient travel distance, failing to meet cutting specifications
Solution Approach 1:
The patent implements a dynamically adjustable platen movement mechanism where the movement distance can be extended beyond the standard cutting dimension. The single platen structure with integrated support platforms allows for increased travel distance to accommodate mounting errors and ensure complete cutting operations. The drive mechanism can adjust the platen's movement range to guarantee that the cutting dimension requirements are always met, even when initial positioning has some error.
3Device complexity
If the cutting tool is disposed on a side of the platen, then the structure is simple, but fragile workpieces need manual support after cutting to prevent breaking
Solution Approach 1:
The patent combines multiple support functions into a single platen structure that includes both a first platform for the workpiece and a second platform for the cut piece, connected through a through-hole. This integrated design maintains structural simplicity while eliminating the need for manual support operations. The unified platen provides continuous support throughout the cutting process, automatically catching and supporting the cut piece without requiring operator intervention.

AI summary
A cutting device includes a box, a workbench disposed on the box, and a cutting assembly disposed on the box, where the workbench includes a platen for carrying a workpiece, and the platen is provided with a first cutting slot along a first direction; the platen is slidably connected to the box along the first direction, and when the platen slides towards the cutting assembly, the cutting assembly penetrates through the first cutting slot so that the cutting assembly cuts the workpiece on the platen, where a slide stroke of the platen is greater than a cutting stroke of the workpiece.
