Abstract
The utility model relates to a diamond wood cutter technical field, the name is PCD spiral banding sword, including the base member, the base member is the columniform structure, and the centre has installation axle reel shaft hole, has the chip groove in the side of base member, has the arch that supports the cutting part at the back at the chip groove, characterized by: the cutting part arch preceding have an one deck PCD layer, the arch divide into two kinds, one kind is that first kinds of hypotenuse shape is protruding, one kind is that both sides second kind backward is protruding, the protruding and second kind arch interval setting of first kinds around the base member, the thickness on PCD layer be 1 -1.5mm, have the advantage that the wearability is good during such PCD spiral banding sword processing panel to the machining precision is high.
Description
Technical field
The utility model relates to diamond woodworking cutter technical field, specifically spiral edge sealing cutter.
Background technology
Spiral edge sealing cutter comprises matrix and blade, and matrix is columniform structure, and have installation shaft or axis hole in the middle of matrix, described blade is arranged on the side of matrix; In prior art, spiral edge sealing cutter is that carbide alloy is made, and it has the shortcoming worn no resistance, thus causes the reduction of its production efficiency.
Summary of the invention
The purpose of this utility model is to provide the spiral edge sealing cutter that a kind of wearability is good, can enhance productivity---PCD spiral edge sealing cutter.
The utility model have employed following technical scheme: PCD spiral edge sealing cutter, comprises matrix, and matrix is columniform structure, and centre has installation shaft or axis hole, has chip area in the side of matrix, has the projection supporting blade after chip area; It is characterized in that: before described blade projection, have one deck PCD layer.
Say further, described projection is divided into two kinds, and a kind of is that the first of bevel edge is protruding, and a kind of is that both sides the second is backward protruding, the first protruding and the second bulge clearance setting around matrix.
Say further, the thickness of described PCD layer is 1-1.5mm.
The beneficial effects of the utility model are: have wearability good advantage during such PCD spiral edge sealing cutter machining sheet, and machining accuracy is high; Described projection is divided into two kinds, and a kind of is that the first of bevel edge is protruding, and a kind of is that both sides the second is backward protruding, and around matrix, the first protruding and the second bulge clearance is arranged, and is more suitable for timber processing use; The thickness of described PCD layer is 1-1.5mm, has and designs more reasonably advantage.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Wherein: 1, cutter hub, 2, chip area 3, protruding 4, PCD layer 5, the first projection 6, the second projection 7, axis hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
PCD is the abbreviation of polycrystalline diamond, and as shown in Figure 1, 2, PCD spiral edge sealing cutter, comprises matrix 1, and matrix is columniform structure, and centre has installation shaft or axis hole 7, has chip area 2 in the side of matrix, has the projection 3 supporting blade after chip area; It is characterized in that: before described blade projection, have one deck PCD layer 4.
Say further, described projection is divided into two kinds, and a kind of is the first projection 5 of bevel edge, and a kind of is both sides the second projections 6 backward, the first protruding and the second bulge clearance setting around matrix.
Say further, the thickness of described PCD layer 4 is 1-1.5mm.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
