Efficient Deburring of Cut Edges with Rolling Body Tools
Here’s PatSnap Eureka !
Summary
Problems
Existing deburring methods for cut edges are inefficient for long edges and those not extending in a straight line, as they require multiple strokes and are limited by the size of the punch and die, leading to increased time and noise.
Innovation solutions
A tool with a rolling body that is longitudinally movable relative to the workpiece, allowing continuous deburring by rolling along the edge and applying pressure, which can be rotated to follow curved or non-linear edges, enabling efficient deburring of long edges and edges of varying shapes.

General conflict description:
Principle concept:
If a press with punch and die is used to deburr cut edges, then burr elimination is achieved, but multiple strokes are required for long cut edges and the process is time-consuming
Why choose this principle:
The rolling body enables continuous deburring action along the entire cut edge through rolling motion, eliminating the need for multiple discrete strokes. The rolling body continuously applies pressure and moves along the cut edge in one continuous operation, maintaining useful action throughout the deburring process.
Principle concept:
If a press with punch and die is used to deburr cut edges, then burr elimination is achieved, but multiple strokes are required for long cut edges and the process is time-consuming
Why choose this principle:
The rolling body introduces dynamic motion to the deburring process, replacing the static press-and-hold mechanism with a rolling motion that continuously progresses along the cut edge. This dynamic approach allows the tool to adapt to the cut edge geometry while maintaining continuous contact and deburring action.

Abstract
A tool for deburring cut edges on workpieces has a pressure body in the form of a rolling body, by means of which, as relative longitudinal movement of rolling body and workpiece takes place, pressure can be applied to the burr on the relevant cut edge in the direction towards the workpiece while the rolling body rolls along the cut edge. A machine for deburring cut edges on workpieces is provided with a tool of the above-mentioned kind. In the course of a process for deburring cut edges on workpieces, a rolling body is moved along the relevant cut edge with a rolling motion. In that movement, pressure is applied by means of the rolling body to the burr on the cut edge in the direction towards the workpiece.
