AI Technical Summary
Technical Problem
Existing chamfering machines struggle to handle steel girders with varying thickness and width gradients, leading to inconsistent chamfer quality and the need for increased manpower due to manual adjustments.
Method used
A self-propelled chamfering machine with a trolley equipped with running wheels, a cutter, main and guide rollers, and a magnet that stabilizes travel on steel girders, allowing it to chamfer corners while adapting to gradients in thickness and width directions.
Benefits of technology
The machine ensures consistent chamfer quality and reduces manpower requirements by automatically adjusting to gradients, enhancing paint adhesion on steel girders.

Abstract
The aim is to stabilize quality, reduce the labor required for chamfering, and enable the production of steel girders with a gradient in the thickness direction. [Solution] The self-propelled chamfering machine 1 is a machine that travels along one side of the upper surface of a steel girder 2 in the direction in which the steel girder 2 extends, and chamfers the corner of the upper end face of this one side. The machine comprises a trolley 4 equipped with running wheels 3 that travel along the upper surface of the steel girder 2 and are positioned to move obliquely toward the other side; a cutter 5 positioned on one side of the trolley 4 that cuts and chamfers the corner of the upper end face of one side of the steel girder 2; a main roller 6 and a guide roller 7 that contact the end face of one side of the steel girder 2 and guide the trolley 4 to travel along that side; and a front auxiliary wheel 9 on the other side of the trolley 4 that supports the trolley 4 so that it can travel relative to the upper surface of the steel girder 2. The front auxiliary wheel 9 supports the trolley 4 at approximately the same front-to-back position as the running wheels 3 positioned at the very front of the self-propelled chamfering machine 1.
