Description

[Technical Field]

[0001] This utility model relates to the technical field of processing and production equipment, and in particular to a swing frame mechanism for processing the smooth R-shaped edge of sheet metal in the field of deep processing of sheet metal. [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. [Utility Model Content]

[0005] In view of this, the technical problem to be solved by this utility model is to provide a swing frame mechanism for processing the smooth R-shaped edge of sheet metal workpieces, which can process the clear outline of the arc surface of the R-shaped edge.

When the grinding wheel device swings, it contacts one right-angled edge and two edge surfaces of the plate workpiece being processed, thus realizing the grinding action.

[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 placed below the swing frame, and the swing frame ranges from 0 degrees to -90 degrees, or the rotation radius of the crank mechanism is changed to be less than 0 degrees to greater than -90 degrees; this is called the downward swing action.
