Description
Technical field
The present invention relates to materials processing technology field, be specifically related to a kind of preparation method of copper steel self-lubricating composite plate material.
Background technology
Copper steel self-lubricating composite plate material, it is the self-lubricating composite be made by rolling after using copper and steel plate mutually to sinter, normally hardness and the higher bearing metal of modulus of elasticity, to ensure to be made into bearing and to have higher bearing capacity, compacted degree intensity, wearability, and less elastic deformation and plastic deformation.But some shortcoming of the technological process of production of copper steel self-lubricating composite plate material at present, cause the copper steel self-lubricating composite plate material produced, bonding force is inadequate, and product quality is poor.
Summary of the invention
For solving the problem, the invention provides a kind of preparation method of copper steel self-lubricating composite plate material, it is reasonable that it has technological process, and firmly, production cost is low, the advantage that product quality is high for composite board bonding.
Technical problem to be solved by this invention realizes by the following technical solutions:
A preparation method for copper steel self-lubricating composite plate material, it comprises the following steps:
A, blanking: copper coin, steel plate are cut for subsequent use by certain size;
B, surface clean: process in early stage is carried out to the surface oxide layer of the copper coin cut, steel plate, first immersion is carried out 20 ~ 30 minutes to copper coin, steel plate, then polish, again through pickling, use clean water twice more afterwards, do antirust treatment again, test again after the sheet material after process is dried; Qualified sheet material stays with for subsequent use, and underproof sheet material repeats aforesaid operations until qualified; By oxide layer and the dirt on the method removal steel such as above-mentioned pickling, polishing, copper bi-material surface, the existence of this type of material can make bi-material in recombination process not to be fused, so must clean up, removes oxide layer;
C, surface pretreatment: cleaned bi-material is smoothed, then composite surface is carried out fluffing process, to increase compound firmness; Operation of wherein fluffing is the most important, and its area coverage must reach more than 90%;
D, Combined Processing: because compound tense contact surface temperature is high, composite base plate surface is easily oxidized, form oxide layer, simultaneously because plied timber is different from the fusing point of parent metal, binding site easily produces melting loss, therefore need to smear one deck high-temperature anti-oxidant and auxiliary agent at composite surface surface uniform, the quality of guarantee product, its Main Function is when hot environment reaches critical-temperature, the mobility that auxiliary agent contributes to low melting point increases sharply, thus reach the object mutually merged, by be coated with wipe the bi-material of auxiliary agent bonded to each other together after, put in high temperature sintering furnace, gas shield is carried out by vacuumizing and be filled with nitrogen, sinter in the temperature of 700 ~ 900 DEG C, by auxiliary agent and the self-propagating effect of self, bi-material is closely combined with each other, thus become as a whole,
E, smoothing, extruding: the sheet material good to compound is smoothed, and extrudes on roll squeezer.
The invention has the beneficial effects as follows: present invention process flow process is reasonable, use Self-Propagating High-Temperature Synthesis Welding technology, and the composite surface of copper steel sheet material is carried out to fluffing process, smears high-temperature anti-oxidant and auxiliary agent, make copper steel sheet material compound more firm, reduce production cost, improve the quality of products.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A preparation method for copper steel self-lubricating composite plate material, it comprises the following steps:
A, blanking: copper coin, steel plate are cut for subsequent use by certain size;
B, surface clean: process in early stage is carried out to the surface oxide layer of the copper coin cut, steel plate, first immersion is carried out 20 ~ 30 minutes to copper coin, steel plate, then polish, again through pickling, use clean water twice more afterwards, do antirust treatment again, test again after the sheet material after process is dried; Qualified sheet material stays with for subsequent use, and underproof sheet material repeats aforesaid operations until qualified; By oxide layer and the dirt on the method removal steel such as above-mentioned pickling, polishing, copper bi-material surface, the existence of this type of material can make bi-material in recombination process not to be fused, so must clean up, removes oxide layer;
C, surface pretreatment: cleaned bi-material is smoothed, then composite surface is carried out fluffing process, to increase compound firmness; Operation of wherein fluffing is the most important, and its area coverage must reach more than 90%;
D, Combined Processing: because compound tense contact surface temperature is high, composite base plate surface is easily oxidized, form oxide layer, simultaneously because plied timber is different from the fusing point of parent metal, binding site easily produces melting loss, therefore need to smear one deck high-temperature anti-oxidant and auxiliary agent at composite surface surface uniform, the quality of guarantee product, its Main Function is when hot environment reaches critical-temperature, the mobility that auxiliary agent contributes to low melting point increases sharply, thus reach the object mutually merged, by be coated with wipe the bi-material of auxiliary agent bonded to each other together after, put in high temperature sintering furnace, gas shield is carried out by vacuumizing and be filled with nitrogen, sinter in the temperature of 700 ~ 900 DEG C, by auxiliary agent and the self-propagating effect of self, bi-material is closely combined with each other, thus become as a whole,
