Abstract
A screw steel tapping hole expanding drill belongs to a special tool in the field of steel making equipment and is developed for the problem that the cutting performance of a cutter head on the existing steel tapping hole expanding drill is not ideal. The drill mainly consists of a conical drill body and cutter heads, wherein the cutter head is embedded on the conical surface of the drill body, and arranged in the form of a double-head screw line and meanwhile, assumes a plurality of straight lines along longitudinal direction; a chip groove in the shape of a double-head screw line is processed between the cutter heads on the conical surface; and the installation section at the lower part of each cutter head is cylindrical, and the cutting section at the upper part of the cutter head is square. The layout of the cutter heads are reasonable, thus ensuring the precision of the steel tapping hole expanding drill and improving the use performance of the drill. The corner of the cutting blade of the square cutter head is sharp and good in cutting performance, thus increasing the cutting speed of the steel tapping hole expanding drill and improving the efficiency of drilling and expanding holes. The screw steel tapping hole expanding drill can be applied to the steel tapping hole drilling and expanding work of a revolving furnace and other steel making furnaces.
Description
Technical field
The utility model belongs to the special tool in steelmaking equipment field, mainly relates to converter taphole is holed and the volution tap hole reaming bit of ream operation.
Background technology
Tappinghole drilling bit of the prior art generally is that conical frame of the bit is provided with columniform cutter head or blade.Because described frame of the bit is conical, the arrangement of cutter head on cone surface will have certain rules, otherwise easily makes the cutting force at each position unbalanced, causes the damage of part cutter tip.In addition, the cutting ability of cylindrical cutter tip is also not ideal enough, and is bigger to the hole drilling and reaming speed influence that improves Tappinghole drilling bit.
Summary of the invention
The purpose of this utility model provides a kind of volution tap hole reaming bit, the structure of this tap hole reaming bit and cutter head rationally distributed, excellent cutting performance.
The utility model is realized by following measure.Mainly be made up of conical frame of the bit and cutter head, it is characterized in that: cutter head is installed on the cone surface of frame of the bit, presses the form of bipitch helical line and arranges, and longitudinally is many linears simultaneously; Be processed with the linear junk slot of twin-feed spiral in the position between the cutter head on the cone surface; The installation position of cutter head bottom is cylindrical, and the cutting position on top is square.
The beneficial effects of the utility model are that on the frame of the bit of tap hole reaming bit, cutter head is the linear arrangement of twin-feed spiral, longitudinally is many rectilinear structures simultaneously, makes the layout of cutter head more reasonable.Guarantee the precision of tap hole reaming bit, improved the use properties of drill bit.Spiral junk slot can improve the chip removal performance of reaming bit, and particularly the effect behind tool bit abrasion is more obvious.The basil of side's cutter head cutting edge is sharp, and cutting ability is good, has improved the cutting speed of Tappinghole drilling bit, has improved the efficient of boring and reaming.Can be applicable to the boring and the ream operation of steel melting furnace tap holes such as converter.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, and 1 is frame of the bit, the 2nd among the figure, cutter head, the 3rd, volution junk slot.
Embodiment
Below in conjunction with a description of drawings embodiment of the present utility model.The frame of the bit 1 of tap hole reaming bit is conical, and cutter head 2 is installed on the cone surface of frame of the bit 1, presses the form of bipitch helical line and arranges, and longitudinally is eight linears simultaneously; Position between cutter head on the cone surface 2 is processed with the linear junk slot of twin-feed spiral 3; The installation position of cutter head 2 bottoms is cylindrical, and the cutting position on top is square.
