Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of processing and production equipment technology, and in particular to a swing frame mechanism for processing the R-shaped edge on the back of a sheet material in the field of deep processing of sheet materials. [Background Technology]
[0002] In existing technologies, most of the slabs are made of sintered stone, stone, or glass. For deep processing of the peripheral edge radius of the slabs, the peripheral edge radius is generally ground and polished using an inner radius-forming wheel to achieve the desired radius reduction.
[0003] In use, the sheet material to be processed is first fixed in the designated position. Then, the grinding forming wheel grinds the edges around the fixed sheet material. Following this, the material undergoes rough grinding, semi-fine grinding, and precision grinding processes to achieve the predetermined radius requirement.
[0004] During the grinding process described above, the uneven wear of the inner radius profile during the grinding and polishing of the inner R forming wheel causes irregular deformation of the edge profile of the sheet metal workpiece being processed, which in turn causes irregular deformation of the R-shaped edge of the sheet metal workpiece being processed.

[0013] During grinding, the right-angled edge of the plate to be processed is placed at the inherent center point of the swing mechanism, and the grinding head wheel device swings back and forth with the plate workpiece as the center.
[0014] The grinding wheel device is positioned above the swing frame, which has a range of 0 to 90 degrees, or the rotation radius of the crank mechanism is changed to be greater than 0 degrees and less than 90 degrees; this is called the upward swing action.
