Abstract
A blade plate comprises a periphery 5, the back face side of which is covered with an abrasion-resistant metal layer 2b,the abrasion-resistant metal layer 2b is adhered to the back face side of periphery 5 by spray-plating and melt-cooling.
Description
The present invention relates to a kind of technology that can improve the circular saw blade wearability, be specially adapted to cut circular saw blade stalk device on of device at combine.
In the prior art, there is a kind of combine to have as everyone knows and cuts the stalk device in order to the useless stalk that cuts off rice, wheat or similar crops results, threshing.Cut in the stalk device this, have pair of rotary shafts to be provided with in front and back respectively in parallel with each other.All be installed with a plurality of circular saw blades on each rotating shaft, and the two-wheeled blade is parallel to each other.Each page blade all is the discoid blade of periphery indentation.Useless stalk can be thrown on the field after being amputated by between the blade of rotating shaft before and after throwing into.
Cut the conventional circular saw blade that uses of stalk device, its blade makes it hardening by technologies such as burning sclerosis, quenchings.Yet when having cut a large amount of useless stalks, blade will soon be worn.So cutting performance can be impaired, the useless stalk that causes not being cut is thrown or useless stalk blocks cutter sweep and reduce the work efficiency of this device.In this case, the blade of damage just needs sharpening or more renews blade, and doing so very loaded down with trivial detailsly maybe need increase expense.Therefore, people wish that circular saw blade can keep good cutting performance in one period long period.
The objective of the invention is to address the above problem, and solution and effect thereof will be stated below.
A kind of circular saw blade 1 comprises a cutter blade disk 1a with outer peripheral edges 5.The front surface of outer peripheral edges 5 one sides is sharp facet 2a, and the rear surface of opposite side is that one deck antifriction metal (AFM) layer 2b covers, and therefore, forms a lamination blade 2.
According to the present invention, when the facet 2a of lamination blade 2 was worn, antifriction metal (AFM) layer 2b was then outstanding from the facet 2a that is worn, thereby kept the good cutting performance of circular saw blade 1, and the corresponding further wearability that improves circular saw blade 1.
In addition, by spraying plating and consolidation antifriction metal (AFM) layer 2b is attached to the surface of outer peripheral edges 5.In this way, the wearability of antifriction metal (AFM) layer 2b is improved, and has further improved the wearability of circular saw blade thus.
Below in conjunction with accompanying drawing, describe the circular saw blade in one embodiment of the present of invention in detail.
Fig. 1 is the front view of whole circular saw blade 1 of the present invention.
Fig. 2 is the rearview of same whole circular saw blade 1.
Fig. 3 is the local enlarged diagram of circular saw blade 1 among Fig. 2.
Fig. 4 be among Fig. 2 lamination blade 2 at the cutaway view of A-A direction.
Fig. 5 is the cutaway view after the lamination blade 2 among Fig. 4 is worn.
At first for circular saw blade of the present invention is applicable to cutting on the stalk device of a combine, a large amount of blades will be fixed on the rotating shaft parallel to each other in the cutter sweep.Combine results be the straw of band grain, and they are transferred in the sheller unit, the useless stalk after the threshing blade 1 in the device to be cut again is sawed-off.
Introduce the structure of cutter blade 1 below.As shown in Figure 1, 2, 3, the center of cutter blade disk 1a offers a polygon (being hexagon in the present embodiment) the connecting hole 1b that can allow the rotating shaft of cutter sweep insert.The excircle of disk 1a is provided with jagged outer peripheral edges 5.The sawtooth of outer peripheral edges 5 constitutes by alternately arranging as the skew lines part 3 of crown and tooth root and curved portion 4 respectively.The cutter blade disk 1a that has outer peripheral edges 5 is by making such as the so quite hard raw material of steel.
As shown in Figure 4, thus the excircle of cutter blade disk 1a bends towards the front side forms broken line on cross section.The front surface of outer peripheral edges 5 is polished with substantially parallel with cutter blade disk 1a, forms a facet 2a.The rear surface of outer peripheral edges 5 is coated with antifriction metal (AFM) layer 2b.Facet 2a and metal level 2b constitute lamination blade 2.Metal level 2b sticks on the rear surface of outer peripheral edges 5 by spraying plating and consolidation mode.Subsequently, metal level 2b is melted again, so just formed fine and closely woven hard lamination by heating under the temperature between 1050 ℃-1100 ℃.
Preferably, metal level 2b is that its Rockwell hardness is between 55 to 60 in 120 °, the hardness test of the coniform diamond pressure head of terminal surface radius 0.2mm adopting a drift angle.
Describe below in conjunction with the function of attached Figure 4 and 5 lamination blade 2.
Each page circular saw blade 1 that cuts on the stalk device that is connected combine all can be worn along with the sawing of long-time repeatability.In this wear process, the shape of lamination blade 2 gradually becomes shown in Fig. 5 by shown in Fig. 4.Here, the wearability of the light face 2a that is made by steel or similar material will be lower than the wearability of metal level 2b, so that light face 2a is ground off for 4 li from crown quickly than metal level 2b.So metal level 2b just highlights from light face 2a as shown in Figure 4 like that gradually.
If the front and rear surfaces of outer peripheral edges 5 resembles conventional art and does not cover metal level 2b employed and hardened, or two surfaces of outer peripheral edges 5 all cover metal level 2b, will being worn and torn simultaneously in former and later two surfaces of each crown 4, thereby makes crown 4 become circle, makes cutting performance impaired.If two surfaces of outer peripheral edges 5 all do not cover metal level 2b, then wearing and tearing can be very fast.
According to lamination blade 2 of the present invention, the apparent surface who is coated with metal level 2b on the outer peripheral edges 5 is along with sawing meeting very quick-wearing, yet antifriction metal (AFM) layer 2b can stay, thereby as described abovely highlights from the light face 2a that is worn like that.Outstanding metal level 2b forms a sharp blade, and has greatly been hardened by spraying plating and consolidation, so can keep the cutting performance of cutter blade 1.
So the anti-wear performance of circular saw blade 1 improves, thereby change the quantity of blade or the time of the blade of refacing has been reduced.Therefore, the straw of combine results can be cut effectively.
