Abstract
The utility model relates to a sheet material for machining cutters, specifically a composite board for machining the cutters. The composite board of three layers is formed by that an 8Cr17Mo steel plate and a stainless steel plate are precisely and explosively welded. After the original single layer is changed into a multilayer composite structure in the utility model, the utility model, compared with the original structure, has the advantages of bending resistance, high shock resistance, wear-proof and sharp cutting edge, corrosion resistance, bright maintenance, etc.
Description
The utility model relates to the plate of process tool, specifically a kind of composite plate that is used for process tool.
At present, people common Kitchen knife cutting edge raw material be 65Mn, its hardness number is higher, is easy to produce hardening flaw in the processing, cutting edge and surface are easy to corrosion during use.The common stainless steel cutter can resistant to rust, but that its shortcoming is a hardness is on the low side, and cutting edge is sharp inadequately.
The purpose of this utility model is the shortcoming at above-mentioned existence, and a kind of sharp and corrosion protection Composite sheet for knife of cutting edge that improves is provided.
Technical essential of the present utility model is:
It is to adopt 8Cr17Mo alloy-steel plate and the accurate explosive welding of 1Cr13 corrosion resistant plate to constitute 3 layers of composite plate.The composite plate intermediate layer is the 8Cr17Mo corrosion resistant plate, also can adopt 7Cr17Mo, 9Cr17Mo, 8Cr17,7Cr17 corrosion resistant plate.The both sides layer of composite plate is the 1Cr13 corrosion resistant plate, also can adopt 304 corrosion resistant plates.
The utility model is compared with original structure after having become multi-layer compound structure by original individual layer, has bending resistance, shock resistance height, cutting edge is wear-resisting, sharp, resistant to rust, protect advantage such as light forever, not only in process, be difficult for producing hardening flaw, and its long service life.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
From accompanying drawing as seen, it is that the synthetic both sides of accurate explosive welding are the three-layer composite structure of 1Cr13 stainless steel (1) therebetween 8Cr17Mo alloy-steel plate (2).Be that 8Cr17Mo alloy-steel plate (2) is synthetic with stainless steel (1) blast.Its manufacture process is: the cleaning combination interface exposes fresh, clean active surface, and at the explosive of clad surface cloth last layer uniform thickness, behind cap sensitive explosive, the detonation wave slippage produces surge by multiple layer, make it and the base material generation metal jet that collides at an angle, under HTHP, realize metallurgical binding.Three ply board base after the seam by the requirement of metallic intermediate layer characteristic, is made the desired size of cutter through hot rolling and cold rolling reaching.Every layer thickness of three-layer composite board is basic identical, and the gross thickness of three-layer composite board is respectively 1.7mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm and 4.0mm.
By the product that this composite is made, not only sharp but also stainless, not tipping, constantly sword, not turned, do not ftracture, not delamination, be to make the preferred material that requires the stainless again cutter product of blade hardness height, be the plate of a kind of novelty in the cutter processing industry.
Claims (3)
1. three layers of Composite sheet for knife are platy structure, it is characterized in that adopting 8Cr17Mo steel plate and the explosive welding of 1Cr13 corrosion resistant plate to constitute 3 layers of composite plate.
2. according to the described three layers of Composite sheet for knife of claim 1, it is characterized in that the composite plate intermediate layer is the 8Cr17Mo corrosion resistant plate, also can adopt 7Cr17Mo, 9Cr17Mo, 8Cr17,7Cr17 corrosion resistant plate.
3. according to the described three layers of Composite sheet for knife of claim 1, the both sides layer that it is characterized in that composite plate is the 1Cr13 corrosion resistant plate, also can adopt 304 corrosion resistant plates.
