Abstract
Belongs to a high wear-resistant steel wire tire crushing cutter in a steel wire tire crusher, which is mainly characterized in that: the front and upper surfaces of the parent material of the cutter are overlaid with a layer of high-wear-resistance material by a wear-resistant welding rod or welded with hard alloy, or the parent material of the cutter is made of alloy tool steel or high-speed tool steel. The wear-resistant cutter solves the problem that the front and the back of the cutter in the prior art are not wear-resistant, and the service life of the cutter is greatly prolonged.
Description
The invention belongs to a kind of crushing cutter of high wear-resistant steel wire tyre in the rail tyre disintegrating machine.
Cutter in the rubber disintegrating machine that is using in the prior art is that carbide alloy is welded on the common iron.Because the carbide alloy wearability is fine, and the common material wearability is very poor, so in use, the front of cutter and top fertile material are gone very big one soon by the steel wire wear in the rail tyre.And surface wear can influence the fastening force of fastening bolt on the cutter, and cutter is loosening easily; Surface wear before the cutter can make carbide alloy unsettled, when unsettled to a certain degree the time, carbide alloy will break, thereby causes whole cutter to scrap that (compression strength of carbide alloy is big, and bending strength is little, poor toughness, thus unsettled to a certain degree the time one stressed will breaking).Cutter is often scrapped replacing, causes production cost too high, and the user can't accept.
Summary of the invention:
The purpose of this invention is to provide a kind of front of fertile material and the crushing cutter of high wear-resistant steel wire tyre that top wearability increases substantially.
The technical solution adopted for the present invention to solve the technical problems is: with wear resistance electrode built-up welding one deck wearing layer, also use wear resistance electrode built-up welding one deck wearing layer on the fertile material below the front of carbide alloy on the fertile material of the back of carbide alloy; Or carbide alloy on fertile material and in the whole welding in front; Or knife edge part is carbide alloy, and fertile material adopts tool steel to make, and best fertile material is selected alloy tool steel or high-speed tool steel for use.
The invention has the beneficial effects as follows: because the hardness of wear resistance electrode after being welded on the fertile material is about HRC55 °, can does cutter material and use, can reach its requirement fully so be used as wearing layer.The common material that former fertile material is used is not before having the wearing layer protection, and about broken rail tyre 10T, above the cutter and front is just gone very big one by the steel wire erosive wear, and cutter will be scrapped (see figure 7).After the top and front of cutter fertile material was welded with the wear resistance electrode protective layer, broken 100T rail tyre, carbide-tipped cutter bit were all used and have bluntly been needed sharpening, and wearing layer also almost can't see any wearing and tearing.Second kind of situation: the front of cutter and top all be carbide alloy, the front of cutter and top just more impossible gone by the steel wire erosive wear very big one.The third situation: because the parent material is alloy tool steel or high-speed tool steel, owing to its distinctive anti-wear performance is distinguished heating cooling characteristics with common material, after making itself and carbide alloy add thermal weld, hardness and wearability are very high, so its wearability and wear resistance electrode are approaching.
Below in conjunction with accompanying drawing the present invention is given further instruction:
Fig. 1: be the front view of wear resistance electrode built-up welding cutter of the present invention.
Fig. 2: be the vertical view of wear resistance electrode built-up welding cutter of the present invention.
Fig. 3: be the front of the fertile material of cutter of the present invention and top front view when being carbide alloy.
Fig. 4: be the front of the fertile material of cutter of the present invention and top vertical view when being carbide alloy.
Fig. 5: be the front view of cutter in the prior art.
Fig. 6: be the vertical view of cutter in the prior art.
Fig. 7: be the view after the tool wear in the prior art.
In the accompanying drawing: 1, the carbide alloy of cutter among Fig. 1,2, the fertile material of cutter, 3, the wearing layer of the following surface build-up welding of carbide alloy front among Fig. 1,4, the wearing layer of surface build-up welding behind the carbide alloy among Fig. 1,5, the carbide alloy of cutter front among Fig. 3,6, the carbide alloy among Fig. 3 above the cutter.
The specific embodiment:
First kind of mode is: the fertile material oxygen-acetylene cutting---digs and---bores---build-up wear-resistant layer---pincers worker reconditioning---carbide alloy welding---mill.The second way is: the fertile material oxygen-acetylene cutting---forges---annealing---plane---brill---carbide alloy and fertile material welding---mill (annotate: the third embodiment fertile material should be selected alloy tool steel or high-speed tool steel for use).
Claims (2)
1, belongs to a kind of crushing cutter of high wear-resistant steel wire tyre in the rail tyre disintegrating machine, it is characterized in that: on the fertile material of the back of carbide alloy,, also use wear resistance electrode built-up welding one deck wearing layer on the fertile material below the front of carbide alloy with wear resistance electrode built-up welding one deck wearing layer; Or upward carbide alloy is all welded in the top and front of fertile material.
2, according to the described a kind of crushing cutter of high wear-resistant steel wire tyre of claim 1, it is characterized in that: knife edge part is a carbide alloy, and fertile material is alloy tool steel or high-speed tool steel.
