Forging process of lower bracket connection fork

Abstract

The invention relates to a forging and machining process of a lower bracket connection fork of a vehicle power assembly and aims at providing a forging process of the lower bracket connection fork. The process is used for remarkably improving the machining efficiency and the product performances. The forging process of the lower bracket connection fork is characterized by comprising the following steps of: heating up round bar steel to 1050 DEG C to 1100 DEG C by an electric heating furnace; and forging the round bar steel into a finished product within 45 seconds. Preferably, the round bar steel is heated up to 1085 DEG C to 1093 DEG C by the electric heating furnace. According to the forging process of the lower bracket connection fork disclosed by the invention, simple process improvement is adopted, existing equipment is utilized, and process indexes are adjusted in a varying manner and precisely controlled, so that the product machining period is shortened, and the product machining efficiency and the product performances are improved.

Description

technical field [0001] The invention relates to the forging process of a lower bracket connecting fork on a vehicle power assembly. Background technique [0002] The forging process of the lower support connecting fork in the prior art is generally, using round steel as raw material, first heating and forging to form a rough billet, and then heating and forging again to form a finished product. Heating generally adopts natural gas furnace heating. However, the heating temperature of the natural gas furnace is uneven, because the combustion of natural gas is actually an oxidation reaction process, and it is also easy to cause decarbonization. The whole processing process is complex and long, which makes the internal structure of the metal uneven and shifted, and the grain size increases; the toughness, plasticity, and tensile strength of the product will be affected to varying degrees, so that the product quality and service life will be affected to a certain extent.

However, the heating temperature of the natural gas furnace is uneven, because the combustion of natural gas is actually an oxidation reaction process, and it is also easy to cause decarbonization

The whole processing process is complex and long, which makes the internal structure of the metal uneven and shifted, and the grain size increases; the toughness, plasticity, and tensile strength of the product will be affected to varying degrees, so that the product quality and service life will be affected to a certain extent. Impact

[0003] Moreover, the two-time heating and forging process has a long production cycle, which is not economical and economical in terms of delivery time nodes, human resources, processing costs, etc., resulting in redundant internal consumption
