Embodiment Construction

[0015] The present invention is realized through the following specific embodiments:

[0016] A locomotive connecting rod forging process, comprising the following steps:

[0017] Step 1: blanking, removing the decarburized layer and defects on the surface;

[0018] Step 2: Spray a protective agent on the surface of the billet to form an anti-decarburization coating;

[0019] Step 3: Heat the billet in a furnace at a temperature of 1200-1300°C and keep it warm for 3 hours;

[0020] Step 4: After the billet is naturally cooled, the surface oxide skin layer is removed;

[0021] Step 5: roll forging billet, pull out the rod;

[0022] Step 6: blank forging,

[0023] Step 7: trimming, punching, and correction.

[0024] Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for ...

Abstract

The invention relates to a locomotive connecting rod forging process. The locomotive connecting rod forging process comprises the following steps that 1, blanking is carried out, and a surface carbon fading layer and defects are removed; 2, protective agents are sprayed to the surface of a blank, and a carbon falling preventing coating is formed; 3, the blank is put in a furnace to be heated, temperature ranges from 1,200 DEG C to 1,300 DEG C, and heat preservation is carried out for three hours; 4, the blank is naturally cooled, and then a surface oxidation skin layer is removed; 5, rolling forging blanking is carried out, and a rod portion is drawn; 6, the blank is forged; and 7, trimming, punching and correction are carried out. The locomotive connecting rod forging process is reasonable in process path design, simple and feasible, production efficiency is greatly improved, and meanwhile the surface quality of a locomotive connecting rod workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forging process of a locomotive connecting rod. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. It is one of the two major components of forging (forging and stamping). In the mechanical field, forging is widely used in many aspects, and many auto parts are also processed by forging, such as locomotive connecting rod workpieces. However, in the existing locomotive connecting rod forging process, due to various problems in the process design, the process cycle is long, time-consuming and labor-intensive, the production efficiency is low, and the quality of the locomotive connecting rod workpiece is not satisfactory. Contents of the invention [0003] In order to solve the above-mentioned proble...
