Abstract
The invention discloses a process for preparing a composite wear-resistant component. The process comprises the following steps of: putting one or more metal and non-metal materials into a heating container, and uniformly mixing; heating an obtained mixed material to a temperature at which at least one material is completely fused; fully stirring fused materials and unfused materials to obtain a mixture; pre-heating a mould to a temperature approaching the temperature at which at least one material is completely fused; pouring the obtained mixture into the mould, covering the mould by using a mould cover, and uniformly mixing the mixture in the mould by rotation and vibration of a mechanical device; downwards pressing the mould cover; performing pressing on the upper part of the mould, and gradually reducing the temperature of the mould; when the temperature of the mould is reduced to the normal temperature, standing for a moment for fully cooling; and opening the mould cover to obtain the composite wear-resistant component. Compared with the prior art, the process has the advantages that problems of low strength, narrow application range and the like of the conventional composite wear-resistant material are solved.
Description
Technical field
The present invention relates to component of machine manufacturing technology field, particularly a kind of method of manufacturing technology of wearing piece.
Background technology
Existing composite wear-resistant part is adopt welding or bonding method to be fixed on matrix by high-abrasive material mostly, this method of welding or being adhesively fixed high-abrasive material, because bond strength is not high and there is the defects such as gap between high-abrasive material, easily cause high-abrasive material to come off, have a strong impact on its service life.As the two combined with traditional casting technique, because high-abrasive material physical property difference that is general and matrix material is larger, after there will be matrix material fusing, high-abrasive material is because fusing point is higher and density is lower, always float over this phenomenon of matrix material end face melted, therefore, the two cannot combine by existing casting technique equably.
Summary of the invention
The invention provides a kind of composite wear-resistant part method of manufacturing technology, it can solve in metal casting technique, and the nonmetallic materials of different performance material cannot fuse the problem in metallic matrix.
In order to solve the problem, the technical scheme of this composite wear-resistant part method of manufacturing technology is: this composite wear-resistant part method of manufacturing technology, include following steps: step 101: batch mixing, one or more metal and one or more nonmetallic materials are placed in a heating container and mix; Step 102: heat up, the composite material of gained in above-mentioned steps 101 is heated to the temperature that wherein at least one material melts completely; Step 103: stir, the material melt above-mentioned steps 102 and unfused material stir, and make it abundant mixing, obtain compound; Step 104: mould and die preheating, described mould has bed die, and this bed die is provided with the cavity of upper opening, and described mould and die preheating is to the temperature close with the complete fusion temperature of the material melted completely at first in above-mentioned steps 102; Step 105: pour mould into, after in the described mold bottom die cavity compound of above-mentioned steps 103 gained being poured into above-mentioned steps 104, cover die cover, the bottom end face of this die cover is corresponding with described mold bottom die cavity, and the lateral surface of described die cover is provided with bulge loop; Step 106: mold rotation also vibrates, described mould is rotated by mechanical device and vibrates and material is therein mixed; Step 107: mould pressurizing, in the pressurization of the top of described die cover, makes the inside of described mould produce pressure, is compressed into by the other materials swum on the material surface that melts completely in the material melted completely; Step 108: the slow cooling of pressurize, described mould keeps certain pressure constant, and reduces the heating-up temperature of described mould rallentando; Step 109: normal temperature leaves standstill, after described mold temperature drops to normal temperature, leaves standstill a period of time, allows it fully cool; Step 110: the demoulding, opens described die cover, obtains this composite wear-resistant part.
Owing to adopting technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention has high-abrasive material and matrix material and to combine closely, evenly, and the advantage such as have wide range of applications.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
Fig. 2 is the structural representation of the embodiment of the present invention 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
Composite wear-resistant part method of manufacturing technology shown in Fig. 1, include following steps: step 101: batch mixing, by one or more metal as iron, manganese mix as aluminium oxide ceramics, zirconia ceramics are placed in a heating container by a certain percentage with one or more nonmetallic materials; Step 102: heat up, the composite material of gained in above-mentioned steps 101 is heated to the temperature that wherein at least one material melts completely; Step 103: stir, the material melt above-mentioned steps 102 and unfused material stir, and make it abundant mixing, obtain compound; Step 104: mould and die preheating, mould has bed die 1, and this bed die 1 is provided with the cavity of upper opening, and mould and die preheating is to the temperature close with the complete fusion temperature of the material melted completely at first in above-mentioned steps 102; Step 105: pour mould into, after in mold bottom die 1 cavity compound of above-mentioned steps 103 gained being poured into above-mentioned steps 104, cover die cover 2, the bottom end face of this die cover 2 is corresponding with mold bottom die 1 cavity, and the lateral surface of die cover 2 is provided with bulge loop; Step 106: mold rotation also vibrates, mould namely vibrates the rotation of turntable 3 by mechanical device and vibration makes material therein mix; Step 107: mould pressurizing, is progressively forced into setting value on the top of die cover 2, and pressure setting scope is 0.01-0.2MPa, makes the inside of mould produce pressure, is compressed into by the other materials swum on the material surface that melts completely in the material melted completely; Step 108: the slow cooling of pressurize, mould keeps certain pressure constant, and reduces the heating-up temperature of mould rallentando; Step 109: normal temperature leaves standstill, after mold temperature drops to normal temperature, leaves standstill a period of time, allows it fully cool; Step 110: the demoulding, opens die cover 2, obtains this composite wear-resistant part.
