Whether using stainless steel deburring equipment, cutting or rotating to remove burrs, the angle of the knife is an important factor affecting the effectiveness of deburring. According to the structural characteristics of the burr machine designed in this article, selecting the appropriate cylinder pressure is also one of the main factors determining the effectiveness of burr removal.
2.1 Tool angle.
The burrs at the front end of the billet are knocked off by high-speed rotation of the rotating blade. The four blades are centered around the rotation axis and evenly arranged around it, but the direction of the blades is at an angle to the centerline of the rotation axis.
The burrs on the back end of the billet are scraped off using a flat scraper of a stainless steel deburring device. In order to adapt to the abdominal deformation of the billet, the placement of two flat blades is tilted towards the center, with the horizontal line at a certain angle α， Micro V-shaped, which can protect the surface of the billet from damage and effectively remove burrs.
2.2 Cylinder pressure.
According to the process flow of the combined billet burring machine, when the equipment is in standby position, the cylinder axis is perpendicular to the ground, and the stroke reaches Z value, the structure should be kept horizontal. Stainless steel deburring equipment can calculate the required thrust size of the cylinder through torque balance formula, and then calculate the required pressure size of the cylinder based on the cross-sectional area of the piston.
The online burr removal method for continuous casting blank takes into account the different directions of the Frontend and backend burr of the casting blank. Combined with burr scraping and rotary deburring methods, the Frontend and backend and rear end of the casting blank are separated during transportation, which has a prominent deburring effect. When removing burrs, there is no need to stop casting blank. The equipment has a simple structure, small volume, and convenient maintenance. It can be easily set between two rollers in the roller table, without affecting the placement of other equipment and the rhythm of steel billet production.
