Abstract
The utility model discloses a kind of chip breaker of high-speed steel bit, feature is the projection comprising strip, projection passes through laser powder cladding on the rake face of lathe tool, the length direction of projection parallels with the main cutting edge of lathe tool, the median plane of the length direction of projection is 0.5 ~ 2mm to the vertical range of lathe tool main cutting edge, the front end of projection is 0.5 ~ 3mm to the vertical range of lathe tool front cutting edge, the length of projection is 4 ~ 10mm, bottom width is 0.6 ~ 2.0mm, be highly 0.5 ~ 1.5mm, the bottom width of projection is greater than height; Advantage is because chip breaker is formed on the rake face of lathe tool by laser powder cladding, and its processing is simple, quick, and chip breaking is effective, and easily removes and again manufacture, and only need remove chip breaker with grinding-wheel grinder, and cladding again in place.
Description
Technical field
The utility model relates to the lathe tool for machining, particularly relates to a kind of chip breaker of high-speed steel bit.
Background technology
High-speed steel bit is usually used in the turnery processing of metal material.Often can produce continuous chip in the process of turnery processing, chip can be wound on workpiece, the manufactured surface of the work of scratch; Also can be wound on lathe tool, accelerate wearing and tearing and the breakage of lathe tool; Meanwhile, long chip is also to the security presence hidden danger of operator.At present, conventional chip breaking method grinds chip-breaker on the rake face of high-speed steel bit, but this chip-breaker is generally manual to be ground, and chip breaking effect is unstable, also can affect the follow-up number of times of refacing of high-speed steel bit.Also chip breaking device additional special on lathe tool or knife rest is had plenty of, such as: chip-breaking or chip breaking baffle plate.But the cantilevered length that chip breaking device often needs to increase knife bar is installed, it reduces the rigidity of cutter, have impact on the machining accuracy of workpiece, and, after lathe tool is refaced, also need the position readjusting chip breaking device.Also have plenty of and utilize abrasive machine on the rake face of high-speed steel bit, grind out protruding chip breaker, the Production Time of this chip breaker, worn amount that is long, cutter material was large, and after lathe tool is refaced, need again again on the rake face of lathe tool, to grind new chip breaker, cause the waste of high-speed steel bit material.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of process simple and quick, remove convenient and the chip breaker of the high-speed steel bit of cutter material can be saved.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of chip breaker of high-speed steel bit, comprise the projection of strip, described projection passes through laser powder cladding on the rake face of lathe tool, the length direction of described projection parallels with the main cutting edge of lathe tool, the median plane of the length direction of described projection is 0.5 ~ 2mm to the vertical range of described lathe tool main cutting edge, the front end (namely near one end of Lathe tool tip) of described projection is 0.5 ~ 3mm to the vertical range of lathe tool front cutting edge, the length of described projection is 4 ~ 10mm, bottom width is 0.6 ~ 2.0mm, be highly 0.5 ~ 1.5mm, the bottom width of described projection is greater than height.
The material of described projection is tungsten carbide or aluminium oxide.
The front end of described projection is arc surface, and chip can be made to roll and chip breaking smoothly.
The cross section of described projection is arc.
Described projection is a whole piece or is made up of convex section of 2 ~ 3 spacer segments, is spaced apart 2 ~ 4mm between two adjacent convex section.
Compared with prior art, the utility model has the advantages that because chip breaker is formed on the rake face of lathe tool by laser powder cladding, its processing is simple, quick, chip breaking is effective, and easily remove and again manufacture, only need remove chip breaker with grinding-wheel grinder, and cladding again in place; And when high-speed steel bit is because wearing and tearing are after needs reface, without the need to again grinding chip breaker or chip-breaker, also without the need to adjusting the position of traditional additional chip breaking device, only need re-start laser powder cladding chip breaker on the rake face of lathe tool, can cutter material be saved.

Fig. 2 is the top view of Fig. 1;
Fig. 3 is the top view of the utility model embodiment two.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment one: as shown in the figure, a kind of chip breaker of high-speed steel bit, comprise the projection 1 of a whole piece strip, the material of projection 1 is tungsten carbide and by laser powder cladding on the rake face 3 of lathe tool 2, the cross section of projection 1 is arc, and front end is arc surface, the length direction of projection 1 parallels with the main cutting edge 4 of lathe tool 2, the vertical range D of median plane 11 to the lathe tool main cutting edge 4 of the length direction of projection 1 is 0.5mm, the front end of projection 1 is 1mm to the vertical range M of lathe tool front cutting edge 5, the length L of projection 1 is 5mm, bottom width is 1mm, be highly 0.8mm.
Embodiment two: as shown in the figure, a kind of chip breaker of high-speed steel bit, comprise the projection of strip, projection is made up of convex section 6 of 2 spacer segments, the material of convex section 6 is aluminium oxide and by laser powder cladding on the rake face 3 of lathe tool 2, the cross section of convex section 6 is arc, and front end is arc surface, the length direction of convex section 6 parallels with the main cutting edge 4 of lathe tool 2, the vertical range D of median plane 11 to the lathe tool main cutting edge 4 of the length direction of convex section 6 is 1mm, vertical range M near the front end of convex section 6 of Lathe tool tip to lathe tool front cutting edge 5 is 2mm, total length L between the rear and front end of two sections convex section 6 is 10mm, bottom width is 2mm, be highly 1.2mm, interval H between two convex section 6 is 4mm.
Embodiment three: other structure is with embodiment two, and difference is that projection is made up of convex section 6 of 3 spacer segments, and the total length L between the rear and front end of three sections convex section 6 is 10mm, and the interval H between adjacent two convex section 6 is 2mm.
