Abstract
The invention provides a device for high-speed cutting, comprising two cutter shafts, two blades and two rotary shafts, wherein the two cutter shafts are close to each other and arranged in parallel, and a groove is arranged on the circumferential surface of each cutter shaft along a threaded line which forms an angle with the axial direction of the circumferential surface; the two blades are respectively arranged in the two grooves of the cutter shafts, and cutter points of the two blades are in the same directions with tangential directions of the circumferential surfaces of the two cutter shafts; and the two rotary shafts respectively drive the cutter shafts to rotate. The device for high-speed cutting has the advantages of simpleness in structure, high cutting efficiency and long service life.
Description
Technical field
The present invention relates to a kind of cutter sweep, relate in particular to a kind of device that is used for high-speed cutting.
Background technology
As everyone knows, difform cutter shaft is treated the different effect of being cut with of the article of tailoring, but present; The cut direction of many cutter shafts when the cutting operation is inconsistent; The mass ratio of cutting is lower, on blade, can produce great air drag, and then can influence cutter shaft and turn round stably; And the air-flow that blade is heaved can blow the material that is cut, and sheet flutter for example so also can influence the effect of cutting.
Summary of the invention
A kind of device that is used for high-speed cutting comprises:
Two cutter shafts, close to each other and laterally arrange, on the periphery of said cutter shaft, the edge with its axially at angle threaded line have a groove;
Two blades are separately positioned in the groove of said cutter shaft, and the tangential of the periphery of the knife edge of said blade and said cutter shaft in the same way; And,
Two rotating shafts drive said cutter shaft respectively and rotate.
Wherein, blade is rectangle often, and it is long along the groove setting, and it is wide is its knife edge direction.Blade is arranged in the groove of said cutter shaft, is meant, only the knife edge of blade exposes this groove a little, and other part is contained in the groove fully.
Adopt technique scheme, the quality of cutting can improve and improve greatly.Specifically, common device, even if be provided with groove on its cutter shaft, its blade all is arranged on the outside of cutter shaft.When high-speed cutting was such as wrapping paper, cutter shaft ran up, and stretched out outside blade and will heave air, and this can bring the harm of two aspects: the first, and on blade, can produce great air drag, and then can influence cutter shaft and turn round stably; The second, the air-flow that blade is heaved can blow the material that is cut, and sheet flutter for example so also can influence the effect of cutting.And by contrast, adopting technique scheme, its blade is arranged in the groove; And the tangential of the periphery of its knife edge and said cutter shaft in the same way; In the cutter shaft high speed rotating, it can not heave a large amount of air, therefore like this; Can above-mentioned defective yet, and then can greatly improve the effect of cutting.
In addition, owing to the employing threaded line mode of moving towards of groove, through the experiment contrast, this mode can also further reduce windage, and the cutting resistance of blade also further reduces like this, has optimized cutting effect more in minimizing like this.
Preferably, the axial angle that becomes of said groove and said cutter shaft is 1 to 5 degree.
Further adopt above characteristic, its advantage is that said two cutter shafts can increase substantially the rotating speed of original rotating shaft when rotating cutting, reduce the blade radius of gyration, and the moment of resistance diminishes, thereby reduces power consumption, improves cutting effect simultaneously.
Add man-hour, said rotating shaft turn to needn't be as traditional lathe checker, it can circulate by the another cutter of a cutter without a break, until completion, so efficient is very high.Add general employing carbide alloy shaping blades, and can use high rotational speed, and its inclined guide rails structure can make lathe have bigger rigidity, and be easy to scrap fallaway.
Preferably, said groove is provided with and is used to install the jack of screw of taking the lead, and the said screw of taking the lead is fixed in said groove through thumb pad with said blade.
Preferably, said thumb pad adopts the high-carbon steel that stiffened is handled.
Further adopt above characteristic, its advantage is, adopts thumb pad, and does not use knife rest, can reduce joint gap, can cutter shaft and blade be reinforced, and is not easy to come loose, and has more strengthened the security of this device.In the groove blade can be installed, and improve constantly the crudy and the production efficiency of product, save the cutter expense.Durability is good.For reducing tool change time and making things convenient for tool setting.

The specific embodiment
Below in conjunction with accompanying drawing, more excellent embodiment of the present invention is done further detailed description:
As illustrated in fig. 1 and 2, a kind of device that is used for high-speed cutting, two cutter shafts 10, close to each other and laterally arrange, on the periphery of said cutter shaft 10, the edge with its axially at angle threaded line have a groove 11; Two blades 30 are separately positioned in the groove 11 of said cutter shaft 10, and the tangential of the periphery of the knife edge of said blade 30 and said cutter shaft 10 in the same way; And two rotating shafts 20 drive said cutter shaft 10 respectively and rotate.
The axial angle that becomes of said groove 11 and said cutter shaft 10 is 1 to 5 degree, is preferably 5 degree.
To shown in Figure 5, said groove 11 is provided with and is used to install the jack 32 of screw 31 of taking the lead like Fig. 3, and the said screw of taking the lead is fixed in said groove 11 through thumb pad 33 with said blade 30.
The high-carbon steel that said thumb pad 33 adopts stiffened to handle.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
