Hot-die forging system for engine connecting rod

Abstract

The invention discloses a hot-die forging system for an engine connecting rod. The hot-die forging system consists of a blank getting slide table (1), a rough forging robot (2), a hot-die rough forging machine (3), a finish forging robot (4), a hot-die finish forging machine (5), a trimming robot (6), a trimming press (7), a correcting robot (8) and a correcting press (9) which are arranged in a machine room and arranged from the right to the left in sequence, wherein a high-decibel soundproof anti-noise device and a soot purifier are arranged in a room body of the machine room. The hot-die forging system has the benefits that the production efficiency is high, the labor intensity of a worker is greatly relieved, the remote operation can be safely and reliably realized, and clamping damages of the engine connecting rod are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of engine connecting rod production, in particular to an engine connecting rod hot die forging system. Background technique [0002] The automobile industry is one of the pillar industries of my country's national economy, and it will play a very important role in realizing my country's economic plan of "maintaining growth, expanding domestic demand, and adjusting structure". From the analysis of the development plan, actual production situation and development trend of my country's automobile industry and engine industry, it is found that there will be a large demand for new technologies and equipment for connecting rod cracking in recent years. According to the information in the publications of the automobile industry and the statistical data of the engine industry of the National Ministry of Machinery Industry, in the past two years, the annual demand for only the connecting rods of automobiles and agric...

AI Technical Summary

Problems solved by technology

Engine connecting rod is a key component of the engine, but the hot die forging of connecting rods in China is still at a relatively backward level, and on-site production can only be done manually

The on-site environment is quite harsh, and the operation is very dangerous, which seriously endangers the health of the operators. The hazards are as follows: (1) The entire die forging process of the connecting rod is carried out at a temperature higher than 1100 ° C. For such high-temperature objects, artificial Clamping is quite dangerous, and the temperature radiated to the operator's arm is also very high; (2) Multiple punches are frequently stamped, and the impact produces a lot of noise, and the entire operation is completed in a high-noise environment; (3) During the die forging process A large amount of harmful gas will be produced (high temperature oxidation will produce toxic gas, cleaning and cooling the mold will produce a large amount of oil mist and metal dust), the operation is completed in a highly polluted environment; the frequency of connecting rod die forging is high, so manual work is high-intensity also quite high

[0005] In addition, domestic connecting rod hot die forging production technology is low, and its performance characteristics are as follows: (1) Low efficiency: due to the difficulty of manual clamping of high-temperature workpieces, the manual loading and unloading time is long, and the auxiliary working time in a single cycle is long

(2) Unstable quality: Due to manual production, the consistency of the workpiece is poor

(3) High energy consumption per piece: due to the high energy consumption per unit time of forging presses, intermediate frequency induction heating furnaces, etc., the lower the efficiency, the smaller the output with the same energy consumption

(4) There is a large demand for personnel in the die forging process: 7 people / shift, 21 people in the three-shift process, and the labor cost is high
