Problems solved by technology
[0003] The most important part of the water pump is the water pump shaft. During the use of the water pump shaft, one of the shaft sections enters the water, and the other shaft section is used as the rotor of the motor. If the entire shaft of the water pump shaft is made of stainless steel, this will solve the problem However, due to the poor conductivity and high cost of stainless steel, it is not suitable for general use; if the entire axis of the water pump shaft is made of carbon steel, this solves the problem of conductivity and reduces the cost. However, the shaft section in water is prone to rust, so a processing technology that can produce a water pump shaft with good electrical conductivity and no rust is urgently needed in the actual equipment

Embodiment Construction
[0023] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0024] see figure 1 Shown, it is the processing flow diagram of the molding process method of the welding shaft of the present invention;
[0025] Step 1: Blanking: Use a sawing machine to cut off two sections of carbon steel and stainless steel of the corresponding length.
[0026] The carbon steel and stainless steel of a certain length are intercepted respectively by a sawing machine in the press workshop, wherein, the carbon steel adopts 45#, and the stainless steel adopts 303; the length of the carbon steel is 201mm, and its symmetry tolerance is 0.25mm, and the length of the stainless steel is 61.5 mm, its symmetry tolerance is 0.25mm, because described carbon steel and described stainless steel can reduce its length in subsequent processing, so in blanking process, the length of described carbon st...

Abstract
The invention provides a forming process method of a welding shaft. The forming process method of the welding shaft comprises following steps: firstly, utilizing a sawing machine to cut off two segments of carbon steel and stainless steel; utilizing a straightener to correct straightness of carbon steel; using a grinding machine to polish the surfaces of carbon steel and stainless steel; then, using a measuring truck to process evenness of the end surfaces of carbon steel and stainless steel; utilizing an ultrasonic washing unit to surfaces and end surfaces of carbon steel and stainless steel; adopting a friction welding machine to control carbon steel and stainless steel to rotate at high speed and then stops instantly; performing fusion welding to carbon steel and stainless steel by point touch; machining the preliminarily-formed welding shaft by a series of steps; and detecting bending resistance and torsion resistance of the formed welding shaft. The forming process method of the welding shaft has following beneficial effects: the forming process method is operated at ease; the formed welding shaft has high precision and fine coaxiality and abrasion resistance; when the welding shaft is utilized as a water pump, fine conduction performance is realized; and the welding shaft does not rust.
Description
technical field [0001] The invention relates to a process method, in particular to a forming process method of a welding shaft. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. [0003] The most important part of the water pump is the water pump shaft. During the use of the water pump shaft, one shaft section enters the water, and the other shaft section is used as the rotor of the motor. If the entire shaft of the water pump shaft is made of stainless steel, this will solve the problem. However, due to the poor conductivity and high cost of stainless steel, it is not suitable for general ...
