Method for deburring elongate profiled member ends, and brush deburring machine

The method addresses the challenge of uneven deburring in long profiles with non-circular cross-sections by using a transport disc system and adjusting device to optimize the spacing profile, resulting in more precise and even deburring of both edges.

AI Technical Summary

Technical Problem

Existing deburring methods for long profile ends, particularly those with non-circular cross-sections, face challenges in achieving even deburring of both inner and outer edges, as they often require compromises and are not suitable for profiles with varying cross-sections.

Method used

A method utilizing a transport disc system to move long profiles along a path adjacent to rotating roller brushes, with an adjusting device that continuously adjusts the positions of the roller brushes and transport discs relative to each other, allowing for a predetermined spacing profile that optimizes deburring based on the profile's position.

Benefits of technology

This approach enables more precise and even deburring of both inner and outer edges of long profiles with non-circular cross-sections, improving the deburring process by allowing for continuous adjustment of the relative positions of the roller brushes and transport discs.

Abstract

The invention relates to a method for deburring elongate profiled member ends (2a, 2b) of at least one elongate profiled member (2), in that at least one elongate profiled member (2) is placed on a transport disc system (11) and the at least one elongate profiled member (2) is transported by means of a transport disc system (11) in a transport direction (T) and at least one roller brush (7a, 7b) with a roller brush axis (8a, 8b) extending in the transport direction (T) is rotated and the at least one roller brush (7a, 7b) thus comes into contact with the elongate profiled member end (2a, 2b) and deburrs the elongate profiled member end (2a, 2b), wherein positions of the at least one roller brush axis (8a, 8b) and of the transport disc system (11) are adjusted with respect to one other by a adjusting device (9a, 9b) during deburring.
