Abstract
A five-layer metal composite board for machining knives relates to sheet materials to machining kitchen knives, specifically a five-layer metal composite board synthesized by different metal sheet materials. The utility model adopts high carbon steel or high carbon stainless steel, low carbon stainless steel and copper board, the high carbon steel or the high carbon stainless steel is adhered to the low carbon stainless steel and the copper board by accurately controlling the explosive; and is characterized in that a copper alloy board interlayer is provided between the two surface layers of the low carbon stainless steel and the central layer of the high carbon stainless steel board to constitute the five-layer metal composite board. The knife made from the five-layer metal composite board is sharp-edged, stainless and durable; the utility model is the novel sheet materials in knife machining industry.
Description
Technical field
The utility model relates to the plate of processing kitchen used knife tool, and is specifically a kind of by five layers of synthetic composite metal plate of different metal sheet material.
Background technology
The common kitchen used knife tool of people mainly is by high-carbon steel and stainless steel manufacturing.The high-carbon steel cutter is easy to get rusty, and is not attractive in appearance, unhygienic, and stainless steel knife hardness is low, not sharp.Three layers of compound cutter that the applicant once applied for, though can accomplish that cutting edge is sharp, blade is stainless, runs into cutting edge hardness aborning often and reduces, and is difficult for reaching the basic demand of cutter hardness, the interlayer boundary is unclear simultaneously, brings difficulty to automated production processing.
Summary of the invention
The utility model provides a kind of interlayer clearly demarcated at above-mentioned deficiency, has the kitchen used knife tool plate of higher hardness.
The utility model is to adopt high-carbon alloy steel or high carbon stainless steel bonding by accurately controlling explosive method with low carbon stainless steel and copper coin, it is characterized in that being provided with copper alloy plate interlayer (3) between the high carbon stainless steel 8Cr17Mo plate of the low carbon stainless steel plate of two superficial layers (1) and central core (2), constitute five layers of composite plate.
The utlity model has higher bending resistance, shock resistance and hardness.As seen the copper layer helps the raising machine and adds efficient in the system cutter process, and particularly there is a beautiful golden bright line attractive in appearance on clearly demarcated and surface at finished product cutter interlayer, and copper ion exists and also has certain antibacterial action.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
From accompanying drawing as seen, it is five layers of synthetic composite construction of accurate explosive welding, and said two superficial layers (1) low carbon stainless steel is 1Cr13 or 304, and the 8Cr17Mo of central core (2) also can adopt CrWMn, and interlayer (3) copper alloy can adopt red copper or brass.The thickness of five layers of composite plate can be selected 1.5mm, 1.7mm, 1.8mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm respectively.Two superficial layers (1) and central core (2) in five layers of composite plate can be selected similar thickness, and the thickness of interlayer (3) is 0.05～0.20mm.
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 layers of material with certain angle generation metal jet that runs foul of each other, under HTHP, realize metallurgical binding.
By the cutter that five layers of metal composite plate are made, sharp stainless, do not collapse constantly, blade remains high rigidity, can reach HRc62 °, and product is really accomplished elegant in appearance, and is durable in use, is the plate of a kind of novelty in the cutter processing industry.
Claims (4)
1. a system cutter is platy structure with five layers of composite metal plate, it is characterized in that being provided with copper alloy plate interlayer (3) between the high carbon stainless steel 8Cr17Mo plate of the low carbon stainless steel plate of two superficial layers (1) and central core (2), constitutes five layers of composite plate.
2. according to the described composite plate of claim 1, it is characterized in that said two superficial layers (1) low carbon stainless steel is 1Cr13 or 304, the high carbon stainless steel 8Cr17Mo of central core (2) also can adopt high-carbon alloy steel CrWMn, and interlayer (3) copper alloy can adopt red copper or brass.
3. according to the described composite plate of claim 1, it is characterized in that the thickness of five layers of composite plate can be selected 1.5mm, 1.7mm, 1.8mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm respectively.
4. according to the described composite plate of claim 1, it is characterized in that two superficial layers (1) and the central core (2) in five layers of composite plate can be selected similar thickness, the thickness of interlayer (3) is 0.05～0.20mm.
