Description

Technical Field

[0001] The invention belongs to the field of diamond drill bit manufacturing, and in particular relates to a diamond thin-wall drill bit base body rounding device. Background Art

[0002] The basic structure of a diamond drill includes a casing and a fixing seat. The casing is connected to the transmission shaft through the fixing seat. Diamond or sintered corundum is installed at the lower end of the casing. The fixing seat is a machined metal connector, and the casing can be selected from a seam steel pipe or a seamless steel pipe. The cost of seamless steel pipe is relatively high, and different sizes of drill bits require seamless steel pipes of different diameters. The amount of drill bits and steel pipes is small, which can easily cause a backlog of raw materials and increase the cost of raw material reserves. Seam steel pipes do not have the above problems. They only need to be equipped with different plates and rolled by a rolling machine according to the needs of different products before straight seam welding. The welded seam steel pipe usually has a certain deformation due to the internal tension, which is a defective product after the fixing seat is welded, which requires rounding treatment in the later stage.
