Low Price 1466110637 diesel injection pump Cam plate 1 466 110 637 VE pump Cam Disk

Design drawings: According to the specific linear profile requirements of the required cam, including the size and shape parameters of each part of the base circle section, working section (straight line ascending section, arc ascending section and arc deceleration section), descending section (maximum lift section and transition arc section), etc., the professional mechanical design software is used to carry out accurate two-dimensional or three-dimensional drawing design.

Selection of materials: Considering that the cam of diesel engine oil pump needs to withstand high pressure, friction and alternating loads in work, alloy steel with high strength, high wear resistance and good toughness is usually selected, such as 20CrNi3A. The quality and performance of the material should meet the relevant standards and design requirements.

Forging billet: the selected steel will be made into a cam billet through the forging process. Forging can improve the internal organization of the material and increase its strength and toughness. The forging process may include the steps of discharging, heating the billet, upsetting the billet, punching and reaming the offset holes, molding in the tire mold, and trimming the billet.

Machining: the blank after forging is machined to achieve the designed accuracy and surface quality requirements. Including turning, milling, grinding and other processes for machining the outer contour of the cam, mounting holes, positioning slots and other parts. In the machining process, it is necessary to use high-precision machine tools and cutting tools, and strictly control the machining parameters to ensure dimensional accuracy and surface roughness.

Heat treatment: Heat treatment, such as quenching and tempering, is carried out on the machined cam to improve its properties such as hardness, strength and wear resistance. Through a reasonable heat treatment process, the organization and structure of the cam can be optimized to meet the working requirements.

Surface treatment: In order to further improve the cam's corrosion resistance and wear resistance, it can be subjected to surface treatment, such as nitriding, hard chrome plating and so on. Surface treatment can form a hard, corrosion-resistant protective film on the cam surface to extend its service life.

Quality Inspection: Adopt a variety of testing methods to conduct quality inspection of cams, including dimensional accuracy measurement, surface roughness testing, hardness testing, flaw detection inspection, etc.. Ensure that the various indexes of the cam meet the design and use requirements, and rework or scrap the unqualified products.

Assembly and debugging: the processed cam and other parts of the diesel oil pump assembly, the assembly process should pay attention to the installation position of the components and the fit gap, to ensure that the cam can work with the roller components and other parts of the normal work. After the assembly is completed, debugging and performance testing, check the cam's working condition and the oil pump's oil supply performance is normal.
