Abstract
The present invention relates to cutting-tool engineering fields, more particularly to a kind of parting-off tool, including knife handle, cutter head, blade, briquetting, cutter groove, deflection is in bowing in order to chip removal backward for the cutter head bottom, the cutter groove is located at knife handle side top, for semi-open structure, cutter groove at the top of cutter head by extending on knife handle；The blade is fixed in cutter groove by briquetting, further includes baffle and extension plate, and the baffle is vertically fixed on cutter groove tail end and forms a recess between cutter groove medial surface；The extension plate is mounted on cutter groove tail portion, and the front end of extension plate is welded on blade tail portion, and the tail end of extension plate is embedded in recess and is fixedly connected by bolt with baffle.The present invention is arranged one piece for blocking and fixing the baffle of blade tail portion in the tail portion of cutter groove, so that parting-off tool is at work, blade will not sideslip, avalanche and cutting speed stabilization.
Description
Technical field
The present invention relates to cutting-tool engineering fields, and in particular to a kind of parting-off tool.
Background technique
In field of machining, the blade of common parting-off tool is the cutter groove that knife handle side top is fixed on by briquetting
Interior, in the slot for the workpiece cut with parting-off tool, more to close at workpiece centre, cutting resistance is bigger, and chip removal is also more, because
This, the blade of parting-off tool easily sideslip at work, or even fall off out of cutter groove.
Summary of the invention
In view of the above-mentioned problems, it is an object of the invention to blade when a kind of work will not sideslip, avalanche and cutting speed is steady
Fixed parting-off tool.
A kind of parting-off tool, including knife handle, cutter head, blade, briquetting, cutter groove, deflection is in bulging backward for the cutter head bottom
Shape is located at knife handle side top in order to chip removal, the cutter groove, is semi-open structure, cutter groove is by extending to knife at the top of cutter head
On handle；The blade is fixed in cutter groove by briquetting, further includes baffle and extension plate, and the baffle is vertically fixed on cutter groove tail
It holds and forms a recess between cutter groove medial surface；The extension plate is mounted on cutter groove tail portion, and the front end of extension plate is welded on
Blade tail portion, the tail end of extension plate are embedded in recess and are fixedly connected by bolt with baffle.
It further, is the strength and stiffness for guaranteeing reasonable chip space and improving blade, cutter head bottom deflection backward
Angle be 10-30 °.
The present invention is arranged one piece for blocking and fixing the baffle of blade tail portion, so that parting-off tool in the tail portion of cutter groove
At work, blade will not sideslip, avalanche and cutting speed stabilization.
Detailed description of the invention
Fig. 1 is a kind of perspective view of parting-off tool of the invention；
Fig. 2 is a kind of decomposition texture schematic diagram of parting-off tool of the invention；
It is as shown in the figure: 1- knife handle, 2- cutter head, 3- blade, 4- briquetting, 5- extension plate, 6- recess, 7- baffle, 8- cutter groove.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
A kind of parting-off tool of the invention as shown in Figure 1 and Figure 2, including knife handle 1, cutter head 2, blade 3, briquetting 4, cutter groove 8,
For deflection in bowing in order to chip removal, the cutter groove 8 is located at 1 side top of knife handle backward for 2 bottom of cutter head, is semi-open knot
Structure, cutter groove 8 at the top of cutter head 2 by extending on knife handle 1；The blade 3 is fixed in cutter groove 8 by briquetting 4, further includes gear
Plate 7 and extension plate 5, the baffle 7 are vertically fixed on 8 tail end of cutter groove and form a recess 6 between 8 medial surface of cutter groove；Institute
It states extension plate 5 and is mounted on 8 tail portion of cutter groove, the front end of extension plate 5 is welded on 3 tail portion of blade, and the tail end of extension plate 5 is embedded in recess
It is fixedly connected in 6 and by bolt with baffle 7.
It further, is the strength and stiffness for guaranteeing reasonable chip space and improving blade 3,2 bottom of cutter head is to retrodeviating
Oblique angle is 10-30 °.
The present invention is arranged one piece for blocking and fixing the baffle of blade tail portion, so that parting-off tool in the tail portion of cutter groove
At work, blade will not sideslip, avalanche and cutting speed stabilization.
