Abstract

The invention provides a high-strength spring guide base for hydraulic system powder metallurgy and a production process thereof. The spring guide base comprises a flange. One end face of the flange is provided with a pair of round bosses used for fixing positions of springs and limiting the center distance between the two springs. One end face of the flange is provided with a plurality of C-shaped steps used for supporting. By means of reasonable material selection and process design, while the requirement for use performance of products is met, the good size precision can be ensured, additional mechanical machining is avoided, by means of the follow-up steam treatment process, the good corrosion-resisting performance of the products can be ensured, and meanwhile, the good surface state and cleanness are achieved. Pollution caused to a plunger pump system can be avoided, the designability of the products is high, the raw material utilization rate is high, the size is stable, precisionis high, the production period is short, and the production cost can be reduced substantially.

Description

technical field

[0001] The invention relates to the technical field of powder metallurgy, in particular to a powder metallurgy high-strength spring guide seat of a hydraulic system and a production process thereof. Background technique

[0002] The servo spring in the hydraulic system of the plunger pump requires a pair of spring guide seats for support, and the existing spring guide seats are generally obtained by casting or machining. However, the dimensional accuracy of castings is poor, and certain machining must be supplemented to meet the dimensional requirements in the later stage. The process flow is more complicated, and the surface state of the workpiece is poor. Machining can guarantee good dimensional accuracy, but the processing efficiency is too low, the utilization rate of raw materials is low, and the cost is too high. And considering the processing cost, the shape and structure of the product itself will also be limited, which cannot meet the lightweight de...
