Abstract
The utility model discloses a cylinder cutter for machining a large-diameter circular hole in a large-scale cylindrical pipe cylinder. The cylinder cutter comprises a cylinder body as a handle, and a plurality of cutter teeth evenly arranged on the end face of the cylinder body. Each cutter tooth is composed of a cutter tooth base body and a blade, wherein the cutter tooth base body is machined on the end face of the cylinder body, the blade is welded to the cutter tooth base body, and the back face, forming a blade cutting edge cutting rear angle, of the cutter is a cambered surface. According to the cylinder cutter, due to the fact that the back face of the cutter is the cambered surface, the anti-impact performance in the interrupted cutting work is greatly improved, the blade is prevented from cracking and losing the teeth, and the working stability of the cylinder cutter is improved.
Description
Technical field
The utility model belongs to tool field on socket, is specifically related to a kind of for process the cylinder cutter of major diameter round hole on large cylindrical shape socket.
Background technology
Cylinder cutter consists of the cylindrical shell as handle of a knife and some cutters tooth of being evenly arranged on cylindrical shell one end face, described cutter tooth is by the cutter tooth matrix processing in body end surface and be welded on cutter tooth matrix cutter and form, and the flank face that forms knife-blade back angle is plane.Cylinder cutter is on large cylindrical shape body or process the cutter of circular hole on cylindrical tube, Main Function is that pipeline body is carried out to perforate operation, it is pipeline, one of important equipment when particularly bigbore pipeline is installed and safeguards, is widely used in fields such as oil, the installation of natural gas equal energy source pipeline and the installations of bigbore urban water supply pipeline.
Cylinder cutter is processed circular hole on large cylindrical shape socket, and as the cutter tooth of cylinder cutter, from start to finish all in discontinuous cutting, cutter tooth, at interrupted working angles, bear very large impulsive force.In addition petroleum transportation pipeline is all the spiral welded pipe being processed into by weld high strength steel, there is welding region and hard point, cause the machining area material of a cutter uneven, as the blade of cutter tooth, be easy to because impact causes collapsing tooth, even fall tooth, cannot complete perforate operation.Therefore the shock resistance of cutter tooth is to determine that can cutter tooth carry out the principal element of perforate operation smoothly.Conventional cartridge cutter cutter tooth, because its flank face that forms cutter tooth cutting edge back angle is plane, thereby cause cutter tooth from point of a knife, cutter tooth material below of blade is removed more, and cutter tooth impact strength reduces, impact resistance a little less than, in its cutting process, blade cutting edge is easy to burst apart, and cylinder cutter lost efficacy, and cannot complete perforate operation.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of for process the cylinder cutter of major diameter round hole on large cylindrical shape tube cylinder, to improve the shock resistance of cylinder cutter blade in interrupted cut work, avoid blade to burst apart, fall tooth, improve job stability.
Described in the utility model for process the cylinder cutter of major diameter round hole on large cylindrical shape cylindrical shell, comprise as the cylindrical shell of handle of a knife and be evenly arranged on the some cutters tooth in body end surface, described cutter tooth is by the cutter tooth matrix processing in body end surface and be welded on cutter tooth matrix cutter and form, and the flank face that forms knife-blade back angle is cambered surface.
Above-mentioned be finally arc surface for process the cylinder cutter of major diameter round hole on large cylindrical shape cylindrical shell after the cutter of described formation knife-blade back angle, and when grinding a tin cutter rear corner surface, employing R circular arc emery wheel is processed.
Compared with prior art, the utlity model has following beneficial effect:
1, the flank face due to cylinder cutter blade described in the utility model is cambered surface, under identical cutter relief angle, compare the cutter tooth that flank face is plane, the material of cutter tooth is removed less, intensity is higher, has improved the shock resistance of blade, avoids blade tipping, falls tooth, more can adapt to interrupted cut, improve job stability.
2, cylinder cutter described in the utility model, the process time of comparing conventional planar flank face process time of flank face being processed into circular arc flank face is shorter, thereby has shortened the manufacturing cycle of cutter, and easy to process, has improved cutter and has manufactured efficiency.
3, the flank face due to cylinder cutter blade described in the utility model is cambered surface, is specially adapted to large type tube cutter rear corner surface, easier for large type tube cutter rear corner surface processing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a cutter tooth of conventional cartridge cutter.
Fig. 2 is the structural representation of a cutter tooth of cylinder cutter described in the utility model.
Fig. 3 is the top view of cylinder cutter integral body described in the utility model.
Fig. 4 is that the A-A of Fig. 3 is to cutaway view.
The object of the shown by reference numeral sign in above-mentioned accompanying drawing is respectively: 1-cylindrical shell; 2-cutter tooth matrix; 3-blade; 4-flank face.
The specific embodiment
Described in the present embodiment on large cylindrical shape cylindrical shell, process major diameter round hole cylinder cutter, its structure is as shown in Fig. 2,3 and 4, comprise as the cylindrical shell 1 of handle of a knife and be evenly arranged on the some cutters tooth in body end surface, described cutter tooth is by the cutter tooth matrix 2 processing in body end surface and be welded on cutter tooth matrix cutter 3 and form, and the flank face 4 that forms knife-blade back angle is arc surface.
Claims (2)
- One kind on large cylindrical shape tube cylinder, process major diameter round hole cylinder cutter, comprise the cylindrical shell (1) as handle of a knife and be evenly arranged on the some cutters tooth in body end surface, described cutter tooth is by the cutter tooth matrix (2) processing on barrel wall and be welded on cutter tooth matrix cutter (3) formation, and the flank face (4) that its spy is to form knife-blade back angle is cambered surface.
- 2. according to claim 1 for process the cylinder cutter of major diameter round hole on large cylindrical shape tube cylinder, its spy is that the cambered surface of described flank face is arc surface.
