Embodiment Construction
[0067] The present invention will be further described below in conjunction with accompanying drawing:
[0068] figure 1 , 2 , 3, and 4 show the structure diagram of the coupling turbine. The position of each part, the inner and outer arc surfaces, blades, runners, mounting holes, and vacant slots must have correct dimensions.
[0069] The chemical substances and materials required for the preparation are calculated and determined according to the preparation of a coupler turbine, and the quantity ratio must be strictly controlled.
[0070] Each chemical material is a solid powder, preferably in the form of fine powder, which is convenient for application and smelting, and is beneficial for alloying.
[0071] The materials are preheated and then added to the melting furnace.
[0072] The coupling turbine is firstly cast into a disc shape by alloy melt, and then heat-treated and tempered to improve the metallographic structure of the casting and facilitate machining.

Abstract
The invention relates to a manufacturing method of a turbine of a copper alloy coupler. The using material of the turbine is quinary alloy of copper, tin, manganese, ferrum and nickel, replaces the original aluminium alloy, and is formed by alloying casting, heat treatment tempering, mechanical slicing, turning and milling by a numerical control processing center so as to manufacture the copper alloy turbine, thus greatly improving the mechanical property, strength, hardness, toughness and wear resistance of the turbine of the coupler, improving the strength by three times, increasing the starting power of the coupler and prolonging the service life of the coupler. The manufacturing method has short process flow, leakproofness, resonableness, high processing accuracy and good reliability,is a very ideal using material and a manufacturing method of the turbine of the coupler and also can be used for manufacturing a pump wheel of the coupler.
Description
technical field [0001] The invention relates to a manufacturing method of a copper alloy coupler turbine, which belongs to the technical field of design and manufacture of torque-limiting coupler parts of conveyors. Background technique [0002] Conveyors are often used for transportation in coal mines, but high-power conveyors have disadvantages such as difficult starting, unbalanced operating load, and lack of effective overload protection. To solve the starting problem, torque-limiting hydraulic couplings are often used. [0003] The main parts in the hydraulic coupling are the turbine and the pump wheel, collectively referred to as the impeller, but the turbine plays a very important role, so the shape, structure and mechanical properties of the turbine are very important. [0004] At present, the hydraulic coupling turbine is made of aluminum alloy sand casting, which is brittle, low in strength, non-wearable, and short in life. Once it is collided, it is easily broken,...
