Grid Cutting Device Shearing Teeth Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Residual sheet metal grids from processing machines are large and unwieldy, hindering production efficiency due to necessary wide transport paths and inefficient use of space, as existing methods like laser cutting or guillotine shears do not effectively break down the grids into manageable pieces.
Innovation Solution
A device with shearing teeth arranged transversely to the grid supply direction, allowing for cutting into smaller pieces by orienting cutting edges to gradually engage and shear the grid, reducing required force and enabling optimal space utilization, with adjustable cutting edges and stroke devices for varying grid thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If residual sheet metal grids are left in complete or folded state, then they can be removed and discarded easily, but wide transport paths are necessary and space in container is not fully used
Solution Approach 1:
The residual sheet metal grids are segmented into smaller pieces using a cutting mechanism with multiple shearing teeth arranged transversely to the grid supply direction. This segmentation reduces the area occupied by each piece, allowing better container space utilization and narrower transport paths while maintaining ease of operation through automated cutting.
2Productivity
If laser machine is used to cut up residual sheet metal grids, then the grids can be comminuted, but the laser machine is not available for processing sheet metal
Solution Approach 1:
The residual grid cutting device uses a segmented cutting mechanism with multiple shearing teeth that can process residual grids independently of the sheet metal processing machine. This allows simultaneous operation - the laser machine processes sheet metal while the cutting device comminutes residual grids, eliminating downtime and maximizing productivity of both systems.
Solution Approach 2:
A separate residual grid cutting device acts as an intermediary system between the sheet metal processing machine and the container. This intermediary device handles the comminution task independently, allowing the primary laser machine to focus on sheet metal processing without interruption.
3Productivity
If guillotine shears are used to break down residual sheet metal grids into strips, then the grids can be divided, but the strips still have the same width and handling remains difficult
Solution Approach 1:
Instead of creating single wide strips like guillotine shears, the cutting mechanism with multiple shearing teeth divides the residual grid into multiple narrower pieces simultaneously. This segmentation in both directions (transverse and longitudinal) creates manageable pieces that are easier to handle and pack efficiently in containers.
Solution Approach 2:
The cutting mechanism cuts in multiple dimensions - not only transversely to the supply direction but also creating pieces of varying lengths. This multi-dimensional segmentation transforms the residual grid from a single large planar object into multiple smaller three-dimensional pieces that optimize container space utilization.
4Productivity
If cutting edges engage the residual sheet metal grid simultaneously along the entire length, then cutting is efficient, but excessive force is required
Solution Approach 1:
The cutting edges are designed with dynamic engagement characteristics - they are orientated obliquely relative to the residual grid supply plane, causing gradual engagement from one end to the other during the cutting movement. This dynamic, progressive engagement maintains cutting efficiency while distributing the required force over time, preventing excessive peak forces.

AI summary
A device for comminuting a residual sheet metal grid includes a grid supply system defining a grid supply plane and supplying the grid in a longitudinal direction; and a cutting assembly including a plurality of shearing teeth extending along a transverse direction transverse to the longitudinal direction. The shearing teeth can include a cutting edge, a cutting edge portion, or both a cutting edge and a cutting edge portion. The cutting assembly can be constructed and arranged to cut the metal grid along the longitudinal direction and the transverse direction.
