Abstract
A through type welding blade for a machine tool comprises a square hard alloy base. Right-angle or triangular grooves are reserved at the positions of four corners of the hard alloy base, a tool tip is connected into each groove in an embedded manner and provided with a hard alloy base layer, and a surface layer made of hard materials such as polycrystalline diamond, polycrystalline cubic boron nitride or the like is arranged on one lateral face or two lateral faces of each hard alloy base layer. The through type welding blade solves the technical problems of fewer cutting edges, complicated welding technology and the like of a common welding blade, the double-head welding solution scheme of a numerical control blade with tool tips includes that the number of cutting edges is larger than that of the cutting edges of the common welding blade, the utilization efficiency of the blade is doubled, compared with the welding mode of a tool tip integrally made of the polycrystalline diamond or the polycrystalline cubic boron nitride, the hard alloy base layers consume less hard materials such as the polycrystalline diamond, the polycrystalline cubic boron nitride or the like, and simultaneously welding strength is improved.
Description
Technical field
The utility model relates to the welding blade of the machining tools such as lathe tool milling cutter of manufacture fields such as a kind of Digit Control Machine Tool.
Background technology
At present, manufacture fields such as Digit Control Machine Tool are used machining tools such as lathe tool milling cutter in a large number, and wherein superhard material welding cutter accounts for very big ratio.The superhard material brazed shank tool all is composite polycrystal-diamond or polycrystalline cubic boron nitride composite sheet to be welded on the hard alloy substrate process.Because the restriction of welding procedure, only cutting edge arranged one-sided, cutting edge reduces 1/2nd than the same specification hard alloy cutter.
The utility model content
The purpose of the utility model is to provide a kind of new type of welding blade, through point of a knife is improved, has realized that numerical control welding blade cutting edge is identical with the same specification carbide chip, has reduced the consumption of hard materials such as polycrystalline diamond or polycrystalline cubic boron nitride simultaneously.
The purpose of the utility model is to realize through following technical scheme:
A kind of lathe is used through welding blade; Comprise hard alloy substrate; Hard alloy substrate is square, all is reserved with square or leg-of-mutton groove at the corner location of hard alloy substrate, and is embedded in formula at groove and connects point of a knife; Said point of a knife has cemented carbide substrate, on a side or two top layers that the side is hard material materials such as polycrystalline diamond or polycrystalline cubic boron nitride of cemented carbide substrate.
The embedded blade that is connected to form of hard alloy substrate and point of a knife, shape can be in square blade, parallelogram blade, triangular blade, the protruding triangular blade any one.
The technical problem that the utility model will solve is that common welding cutter blade is less, and problems such as welding procedure complicacy provide a kind of numerical control blade point of a knife double end welding solution.The common relatively welding blade of this programme has increased blade quantity, makes the utilization ratio of blade improve 1 times; Point of a knife part integral body is the welding manner of polycrystalline diamond or polycrystalline cubic boron nitride relatively, cemented carbide substrate, so reduced the consumption of polycrystalline diamond or polycrystalline cubic boron nitride, weld strength is improved simultaneously.It is a kind of ultimate welding cutter solution.
The utility model makes the production technology of super-hard compound material blade oversimplify, and has solved the problem that the glomerocryst Superhard composite materials is prone to layering, cracks, and is that quality control is more stable, and has increased cutting edge, has improved the utilization ratio of numerical control blade.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the face structure chart of the described lathe of the utility model embodiment with through welding blade.
Fig. 2 is the side-looking structure chart of lathe with through welding blade.
Fig. 3 is the structure chart of point of a knife.
The specific embodiment
Shown in Fig. 1-3, in present embodiment, described a kind of lathe is used through welding blade; Comprise hard alloy substrate 1; Hard alloy substrate 1 is square, all has square or leg-of-mutton groove at the corner location of hard alloy substrate 1, and is embedded in formula at groove and connects point of a knife 2; Said point of a knife 2 has cemented carbide substrate 4, on a side or two top layers 3 that the side is hard materials such as polycrystalline diamond or polycrystalline cubic boron nitride of cemented carbide substrate 1.
The technical problem that the utility model will solve is that common welding cutter blade is less, and problems such as welding procedure complicacy provide a kind of numerical control blade point of a knife double end welding solution.The common relatively welding blade of this programme has increased blade quantity, makes the utilization ratio of blade improve 1 times; Point of a knife part integral body is the welding manner of polycrystalline diamond or polycrystalline cubic boron nitride relatively, the adding of cemented carbide substrate, so reduced the consumption of polycrystalline diamond or polycrystalline cubic boron nitride, weld strength is improved simultaneously.It is a kind of ultimate welding cutter solution.
The utility model makes the production technology of super-hard compound material blade oversimplify, and has solved the problem that the glomerocryst Superhard composite materials is prone to layering, cracks, and is that quality control is more stable, and has increased cutting edge, has improved the utilization ratio of numerical control blade.
