Abstract

The invention belongs to the field of machining and discloses a metal modified gasoline engine link. The metal modified gasoline engine link is prepared from the following raw materials in parts by weight: 100 parts of iron powder, 0.45-0.65 part of molybdenum powder, 0.15-0.35 part of manganese powder, 0.1-0.2 part of chromium powder, 0.3-0.4 part of silicon carbide powder, 0.2-0.3 part of titanium carbide powder, 0.25-0.35 part of aluminum nitride powder, 0.1-0.2 part of barium titanate powder, 0.1-0.2 part of zinc stearate, 0.1 part of talcum powder, 0.1 part of sodium silicate and 0.7-0.9 part of graphite powder. According to the gasoline engine link disclosed by the invention, various metallic raw materials are selected and are reasonably proportioned, so that the mechanical strength, elongation percentage and fatigue strength of the product are improved; according to a production process of the gasoline engine link, no or few cutting scraps are generated, so that link machining procedures are reduced, and workshop, equipment and human resources are saved.

Description

[0001] technical field [0002] The invention belongs to the field of mechanical manufacturing, and in particular relates to a metal-modified gasoline engine connecting rod. [0003] Background technique [0004] The connecting rod is an important part of a small gasoline engine. Its function is to transmit the force borne by the piston to the crankshaft, and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The traditional connecting rod process needs to go through blanking, heating, artificial elongation deformation, heating, die forging, flash removal, sandblasting and other processes to complete the blank process, and then rough machining, heat treatment, semi-finishing, finishing A total of 24 processes are processed. There are many shortcomings in the traditional manufacturing process of connecting rods, mainly including: poor tensile, impact and fatigue resistance, low steel utilization rate, high energy consumption, t...
