Description

A kind of section groove blade of parallelogram

Technical field

The utility model relates to cutting-tool engineering fields, more particularly, to a kind of section groove blade of parallelogram.

Background technique

Section groove blade be for turnery processing, with the cutter of cutting tip, and section groove blade is in machine tooling It is most widely used one of cutter.

Section groove blade includes rake face, side knife surface, flank, main cutting edge and point of a knife, the groove profile in workpieces processing When, Workpiece clamping is rotated in the ring flange of lathe, and it is suitable to give cutter for the position for then bit alignment being needed to process The depth of cut, the processing of the arc groove and end face groove of workpiece can be completed.

Prior art existing defects among the above: it when processing the arc groove or end face groove of same workpiece, needs more Cutter of different shapes is changed, to reach the requirement of processing.Frequent replacement cutter, causes processing efficiency to reduce, so cutter needs It improves, to adapt to the processing of different groove profiles.

Utility model content

The purpose of this utility model is to provide a kind of section groove blades of parallelogram.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of parallelogram Section groove blade, the blade body including parallelogram, the blade body middle part offer mounting hole, the blade body Both ends are equipped with cutting head, and the cutting head includes rake face, flank and side knife surface, the rake face and it is described after The intersecting lens of knife face is main cutting edge, and the crosspoint of the rake face, flank and side knife surface is point of a knife, the side knife surface with The intersection of the flank is the angle point of a knife R of arc-shaped, and the range at the angle the point of a knife R is 0.02mm~0.04mm.

Through the above technical solution, rake face and the intersecting lens of flank are main cutting edge, and main cutting edge can realize work The intersection of the processing of part arc groove, side knife surface and flank is the angle point of a knife R of arc-shaped, and the value at the angle point of a knife R exists Between 0.02mm~0.04mm, the parallelogram blade with the angle different value point of a knife R is selected, workpiece end face slot may be implemented Processing.

Preferably, chip space is provided in the main flank.

Through the above technical solution, chip space can guide the discharge of chip, and chip can be made to generate the interior of overturning Stress and force it deform and fracture, can prevent the surface of workpieces processing because chip scratch due to there is scratch.

Preferably, step-like evacuation side is provided at the knife spine of the blade body.

Through the above technical solution, when carrying out grooving for workpiece, workpiece is divided into machined part and is just processed Part, the setting for avoiding side can make cutter again in progradation, avoid machined part, and then flow process more Freely.

Preferably, two cutting heads are centrosymmetric setting, and at the acute angle in parallelogram.

Through the above technical solution, positioned at the cutting head at blade body both ends, cutting head at one end is ground When damage, the cutting head using the other end can be reversed end for end at once, saves the time for needing replacing another blade.

Preferably, the blade body is made of hard alloy.

Through the above technical solution, blade body is made of hard alloy, and the hardness of blade body can be made high, hot Hardness is good and wearability is good.

Preferably, the surface of the blade body is provided with any one of TiN, TiCN and TiAIN coating.

Through the above technical solutions, cutting-tool's used life can be extended.

In conclusion the advantageous effects of the utility model are as follows:

1. the scope of application of cutter is big；

2. the hardness of cutter is high, thermohardening is good and wearability is good.

Detailed description of the invention

Fig. 1 is the overall schematic of blade body in embodiment；

Fig. 2 is the side view of blade body in embodiment.

Appended drawing reference: 1, mounting hole；2, side is avoided；3, rake face；4, main cutting edge；5, point of a knife；6, flank；7, point of a knife The angle R；8, side knife surface；9, chip space；10, cutting head；11, blade body.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of section groove blade of parallelogram, the blade body 11 including parallelogram are opened in the middle part of blade body 11 Equipped with mounting hole 1, mounting hole 1 is bolted on knife handle, and the both ends of blade body 11 are equipped with cutting head 10, cutting Head 10 includes rake face 3, flank 6 and side knife surface 8, and the intersecting lens of rake face 3 and flank 6 is main cutting edge 4, preceding knife The crosspoint in face 3, flank 6 and side knife surface 8 is point of a knife 5, and the intersection of side knife surface 8 and flank 6 is the angle point of a knife R of arc-shaped 7, and the range at the angle point of a knife R 7 is 0.02mm~0.04mm.In the present embodiment, the value at the angle point of a knife R 7 is 0.04mm.

Specifically, the arc groove processing of workpiece may be implemented in the main cutting edge 4 of blade body 11, the value at the angle point of a knife R 7 exists Between 0.02mm~0.04, in this range, the processing of workpiece end face slot is may be implemented in the angle point of a knife R 7, and in process In, the finish of processing groove profile can be improved.

Two cutting heads 10 are centrosymmetric setting, and at the acute angle in parallelogram, cutting head at one end After portion 10 is worn, the cutting head of the other end 10 can be carried out u-turn use at once, save process time, improve work effect Rate.

Chip space 9 is provided in main flank 6, chip space 9 is arc, for chip to be discharged, chip is avoided to scratch workpiece.

Step-like evacuation side 2 is provided at the knife spine of blade body 11.Blade body 11 is made of hard alloy, and table Face is provided with any one of TiN, TiCN and TiAIN coating, with hardness, the wearability etc. for improving blade, improves the use of blade Service life.

The implementation principle of the present embodiment are as follows: workpiece, which is fixed in the ring flange of lathe, to be rotated, select the angle point of a knife 5R with The blade that the groove profile of required processing matches, blade body 11 are fixedly mounted in knife bar by mounting hole 1, adjust blade sheet Body 11 makes it be directed at workpiece to be processed, gives the suitable depth of cut, the groove profile processing of workpieces processing is completed, in process In, chip fractures discharge from chip space 9.

The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical Within novel protection scope.
