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

The composite wear-resistant part method of manufacturing technology

Technical field

The present invention relates to the method for manufacturing technology in component of machine manufacturing technology field, particularly a kind of wearing piece.

Background technology

Existing composite wear-resistant part is to adopt welding or bonding method that high-abrasive material is fixed on matrix mostly, this method with welding or the high-abrasive material that is adhesively fixed, there are the defectives such as gap due to bond strength between not high and high-abrasive material, easily cause high-abrasive material to come off, have a strong impact on its service life.As both combining with traditional casting technique, because high-abrasive material is general and physical property difference matrix material is larger, after the matrix material fusing can occurring, high-abrasive material is because fusing point is higher lower with density, always float over the matrix material end face this phenomenon that has melted, therefore, existing casting technique can't will both combine 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 can't fuse the problem in metallic matrix.

In order to address the above 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 is placed on one or more metal and one or more nonmetallic materials in a heating container and mixes; Step 102: heat up, the composite material of gained in above-mentioned steps 101 is heated to the temperature that at least a material wherein melts fully; Step 103: stir, material and unfused material that above-mentioned steps 102 is melted stir, and make it abundant mixing, obtain compound; Step 104: mould and die preheating, described mould has bed die, this bed die is provided with the cavity of upper opening, described mould and die preheating to above-mentioned steps 102 in the temperature that approaches of the complete fusion temperature of the material of fusing fully at first; Step 105: pour mould into, after the compound of above-mentioned steps 103 gained being poured in the described mold bottom die cavity of 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 and vibration, described mould are rotated by mechanical device and are vibrated and make within it that the material of section mixes; Step 107: mould pressurizing, in the pressurization of the top of described die cover, make the inside of described mould produce pressure, the other materials that swims on the material surface that melts is fully compressed in the material of fusing fully; Step 108: the slow cooling of pressurize, described mould keep certain pressure constant, and reduce rallentando the heating-up temperature of described mould; Step 109: normal temperature is standing, after described mold temperature drops to normal temperature, standing a period of time, makes it fully cooling; Step 110: the demoulding, open described die cover, namely get 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 in conjunction with closely, evenly, and the advantage such as have wide range of applications.
