Abstract
The composite technology of nickel-copper material-composite electrode for spark plug is characterized by that it adopts mechanical method to insert copper core into nickel rod, and adopts mechanical, physical and chemical methods to make nickel-copper tightly combined into solid nickel-copper composite body. The inside of the composite body is a copper core with good heat-conducting property, and the outer layer is a nickel protective layer with strong high-temperature resistance and chemical corrosion resistance. The nickel-copper interface bonds well and has a diffusion layer of copper to nickel of about 6 μm or more. It is used for manufacturing super spark plugs with wide heat value and excellent technical performance.
The quality of the nickel-copper composite electrode of the spark plug manufactured by the technology reaches the level of similar materials in the international eighties. The capability of processing small-diameter and large-length workpieces exceeds that of expensive foreign high-efficiency automatic combined machine tools.
Description
The present invention is intended to solve domestic spark plug can fully light combustion mixture in combustion chambers of internal combustion engines, reduce exhaust emission, the manufacturing and the complex technique of the ambrose alloy combination electrode of the hot matching range of expansion spark plug and internal combustion engine.
Begun to produce the ambrose alloy combination electrode abroad since the sixties, generally all adopt efficient, combination automation equipment, the advantage of this technology is automaticity height, production efficiency height, but the following shortcoming that is difficult to avoid is arranged.
1. investment is big, and the procuring equipment expense is about more than 1,000,000 dollars;
2. mould therefor material, machined material and lubriation material etc. there are quite high specific (special) requirements, are difficult to realize production domesticization;
3. the consumption of nickel material is big.
Present technique produces the high-quality ambrose alloy composite material with international the eighties level with design cleverly, simple mould, common equipment (as common punch press, vacuum diffusion furnace etc.), its composite material specification, can be with being intended to diameter more than 1.90 millimeters, following any one size point of 40 millimeters of length (or＞40 millimeters) is gone up moulding, and this is that external efficient Automatic Combined lathe is unapproachable.
Present technique make the ambrose alloy composite material-spark plug ambrose alloy electrode as shown in Figure 1.
The shaping step of present technique is arranged as shown in Figure 2.
Critical process has:
1. annealing, workpiece must bury and be contained in the special-purpose take-in box, makes the protection medium with carbon granules, anti-oxidation.Take-in box as shown in Figure 3.
2. the nickel base is anti-crowded cup-shaped, as shown in Figure 4.
3. cup-shaped workpiece cleaning, program is as follows:
Waste vapour oil-clean gasoline (unleaded)-soap lye-clear water-dehydration-liquid detergent (0.01%)-ultrasonic waves for cleaning-inspection-oven dry
4. combination and riveting limit, the signal of riveting banding dress is as Fig. 5.
5. assembly annealing, workpiece annealing temperature is incubated 2-4 hour 650-750 ℃ of scope, is silver gray after the workpiece annealing.
6. undergauge should note keeping the lubricated cooperation that reaches upper and lower mould of mould.Undergauge as shown in Figure 6.
7. upset shoulder as shown in Figure 7.
8. the rammer cross recess as shown in Figure 8.
Claims (1)
- The characteristics of ambrose alloy material complex technique are to utilize the existing equipment of China, material (material that comprises mold materials, workpiece to be machined), produce the sparking-plug electrode material that quality reaches international the eighties level.The copper insertion depth of composite material, all what regular shape gardens are slided, and ambrose alloy intersection copper is to the diffusion layer obvious (generally reaching 6 μ m) of nickel.The present patent application protection range:1, ambrose alloy material complex technique one by one spark plug ambrose alloy electrode make a complete set of mould, technological equipment and detail of design thereof and lubricant;2, use present technique and make spark plug ambrose alloy combination electrode and the derivatives thereof of spark plug with different shape and specification;3, use present technique compound any other two kinds and two or more non-ferrous metal.
