Abstract
The utility model discloses a cutting drill of a drilling machine, which comprises a hollow cutter arbor and a crown positioned at one end of the cutter arbor. Three cutter holders are arranged along the peripheral direction of the crown, a main cutting blade is mounted on each cutter holder, a chip removal hole is disposed between each two cutter holders on the crown and communicated with the cutter arbor, an auxiliary cutting blade is arranged on at least one cutter holder, the main cutting blades and the auxiliary cutting blades are arranged side by side, and the auxiliary cutting blades are positioned on inner sides of the main cutting blades. According to the technical scheme, the auxiliary cutting blades are additionally disposed on the cutter holders, namely the cutting drill of a drilling machine is provided with three edges and at least four blades, and is better in cutting effect and higher in drilling capacity.
Description
Technical field
The utility model relates to a kind of rig cut drill, belongs to field of mechanical technique.
Background technology
The rig cut drill is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming.During bore operation, rock is cut under the moment of torsion of rig cut drill and responsive to axial force, is raveled under extruding and centrifugal action, forms debris flow and presses to hole wall, arrives the face of land along page elevator simultaneously.Stop when place when debris flow moves to imperforate wall and since the centrifugal action rubble thrown the hole around, finish boring procedure.Existing rig cut drill mainly is made up of knife bar and hat body, and the hat body is provided with tool rest, and a blade is installed on each tool rest, and such rig cut drill cutting effect is bad, drilling ability is poor.Prior blade mostly adopts polycrystalline diamond to make in addition, the cost height.
The utility model content
Technical problem to be solved in the utility model is to provide the rig that a kind of cutting effect is good, drilling ability is strong cut drill.
The technical solution of the utility model is as follows: a kind of rig cut drill, comprise hollow knife bar and the hat body that is positioned at knife bar one end, 3 tool rests that are circumferentially with along the hat body, be equipped with the main cutting sheet on each tool rest, hat body between adjacent two tool rests is provided with row and cuts the hole, described row cuts the hole and communicates with knife bar, is provided with secondary cutting blade at least one tool rest, and described main cutting sheet and secondary cutting blade are arranged side by side and secondary cutting tip is positioned at the inboard of main cutting blade.
Adopt technique scheme, set up secondary cutting tip on tool rest, rig cut drill promptly of the present utility model has 3 swords and at least 4 blades, and cutting effect is better, and drilling ability is stronger.
In technique scheme: be provided with secondary cutting blade on a tool rest therein.
In technique scheme, described tool rest, lateral wall be provided with the assisted machining blade.Help hole wall to be shaped, guarantee that hole wall is smooth.
In technique scheme: described main cutting blade and secondary cutting tip are made by carbide alloy, are equipped with one deck polycrystalline diamond layer on the blade of main cutting blade and secondary cutting tip.Blade adopts hard alloy substrate, and one deck polycrystalline diamond layer is set on blade, has saved the use amount of polycrystalline diamond, thereby has saved cost.
In technique scheme, described main cutting blade and secondary cutting tip are circular shear blade.After the part wearing and tearing, blade can be taken off, welding again can reuse behind the rotation transformation position, thereby improves the utilization rate of blade, economizes on resources.
In technique scheme, described main cutting blade and secondary cutting tip are welded on the tool rest.
In order to protect blade, the cutting angle of described main cutting blade and secondary cutting tip is the 10-15 degree.
Beneficial effect: the utility model is reasonable in design, simple in structure, implement easily, drilling ability is strong, be fit to shale and sandstone cutting, rate of penetration height, long working life, cost is low, accident rate is low, and is smooth through the hole wall of boring, do not have to stride and collapse.
