Description
Technical field
The present invention relates to a kind of metal sintering method, be specifically related to a kind of sliding bearing sheet material sintering method and use
Device in the method.
Background technology
Sliding bearing sheet material, for the production and processing of sliding bearing, has the metallic plate of copper alloy powder as base with sintering
Plinth.It is high that sliding bearing sheet material has bearing capacity, and impact resistance, high temperature resistant, self-lubricating capacities is strong, corrosion-resistant
Etc. feature, the product using sliding bearing sheet material to make, it is particularly well-suited to heavy duty, low speed, reciprocal or swing
Etc. being difficult to lubricate and formed the occasion of oil film, be mainly used in making boundary lubrication bearing, Nonlubricated bearing,
Bimetallic bearing three series products.At present product have been widely used engineering machinery, automobile, plastic rubber shaping machinery,
Hydraulic Elements, logistics harbour machinery, punch press metal forming machinery, farm machinery, office equipment, food machinery,
The fields such as energy facilities.
The performance of sliding bearing sheet material is played important work by the sintering process being sintered on metallic plate by copper alloy powder
With；Being sintered in meshbeltfurnace of sliding bearing sheet material is carried out, and meshbeltfurnace sintering is a kind of along with mesh-belt operation stream
Waterline operation, refer mainly to copper alloy powder suitable atmosphere, less than main component fusing point under conditions of add
Heat, realizes connecting between granule by means of atomic migration, copper alloy powder is sintered to copper-plated metal plate or copper closes
Process on gold plate.Copper alloy powder is the alloy powder with copper, stannum, lead, zinc as main component, along with ring
The requirement protected, copper alloy powder tends to unleaded.
In the sintering process of copper alloy powder and copper-plated metal plate, sintering atmosphere can be hydrogen, hydrogen/nitrogen
Oxygen mixture or ammonolysis craft gas.Use ammonolysis craft gas as sintering atmosphere, be possible not only to reducing metal
Plate and the oxide on copper alloy powder, take away the catabolite in sintered body in time, form protective atmosphere gas
Body, it is also possible to reduce the environment impact on goods, maintains the activation phenomenon in sintered material, makes sintered alloy
The serviceability of product is more stable, thus ensures sintering finished quality.The most important thing is can realize burning
The control of stagnation of QI atmosphere.
Owing to the environmental requirement of sliding bearing sheet material sintering is higher, prior art is usually monolayer sintering, this
Production quantity in the method unit interval is relatively low, treating capacity higher in not reaching the short time, in order to improve effect
Rate, has manufacturer to find out and uses galvanized steel plain sheet to do sealing coat between layers at copper-plated metal sheet material, it is achieved multilamellar
Sintering method, but due in sintering process sliding bearing sheet material combine closely with galvanized steel plain sheet, it is impossible to guarantor
Demonstrate,prove the uniformity of heat distribution between layers and sintering atmosphere, thus reduce the performance of sintered products, substantially
Cannot apply.
So being badly in need of a kind of device of invention, for the sintering of multilayer plain bearing sheet material, existing to solve
Sliding bearing sheet material sintering inefficiency, the unstable difficult problem of sintering quality.

3rd step: sampling part middle part bends about 90 degree along layers of copper direction again；
4th step: sampling part middle part is further continued for bending about 180 degree along layers of copper direction.
Differentiate: bend 180 degree of layers of copper has pattern cracking but without delamination, with chisel along chisel layers of copper at Coating combination,
After layers of copper chisels out, if steel plate surface leaves a large amount of copper alloy powder, then bond strength be judged to qualified, such as steel plate
Steel plate surface is stayed without copper alloy powder substantially in face, then bond strength is judged to defective.
Result: the layers of copper bond strength of the 3rd group of sheet material and first group of sheet material is good, and first group of sheet material,
Between every laminate material of three groups of sheet materials and the layers of copper bond strength uniformity of each several part of every laminate material；
Second group of sheet material layers of copper binding strength skewness, topmost the layers of copper bond strength of layer of plate is relatively
Good；The layers of copper bond strength of the sheet material between orlop and intermediate layer steel plate is defective, and in this sheet material
Between part layers of copper bond strength worst, less than the bond strength of surrounding layers of copper.
2, sheet material hardness analysis
Using Brinell hardness analyser to measure the steel plate hardness after sintering, in the middle of every plate and corner is altogether
Measure at five, to reduce error.The results are shown in Table 1, as shown in Table 1:
First group of sheet material, the 3rd group of sheet material hardness good, and between every laminate material of support sintering and every
The hardness uniformity of each several part of laminate material, difference is in 1HB；
In second group of sheet material, the hardness of uppermost sheet material (the 3rd layer) is significantly less than the bottom (the 1st layer)
With intermediate layer (the 2nd layer)；And layers 1 and 2 sheet material middle part hardness is bigger than normal, edge
Hardness is less than normal, and hardness differs by more than 3HB.
The each sheet material of table 1 and hardness/unit HB of each sheet material different parts

3, layers of copper distribution
Accompanying drawing 7-8 be respectively first group of the 10th laminate material (Fig. 7 A), first group of the 4th laminate material (Fig. 7 B),
3rd group of sheet material (Fig. 7 C), second group of the 1st laminate material (Fig. 8 A), second group of the 2nd laminate material (Fig. 8 B),
The metallograph of second group the 3rd layer (topmost one layer) sheet material (Fig. 8 C)；Can be seen that and pass through the present invention
The layers of copper of the sheet material of support sintering is evenly distributed, consistent with monolayer sintering, and uses steel plate to separate the plate of sintering
Material layers of copper skewness.
To sum up, the sliding bearing sheet material sintered by support of the present invention, between every laminate material and every laminate material
Each several part between performance consistent and suitable, without defective products with the performance of monolayer sintering sheet material；Successfully solve
Sheet material sintering inefficiency, a difficult problem for sintering quality instability in prior art of having determined.
