Design of full-automatic forging line robot for transferring and conveying hot forgings

Abstract

The invention discloses a design of a full-automatic forging line robot for transferring and conveying hot forgings. A production line mainly comprises eight forging devices, eight robots, four transfer tables and five cooling pools, wherein hot bars are fully automatically transferred and conveyed between the forging devices according to different stations through the robots by means of the transfer tables; an R2 robot is in direct butt joint with a roll forging hand; and an R7 robot takes the forgings and flashes. The design is capable of transferring and conveying front axles and crankshafts; and the transfer table capable of accurately positioning and detecting incoming materials is adopted in the whole line, and the bus control mode is adopted to realize full-automatic production in the whole line, so that the production efficiency is high, and the failure rate is low.

Description

technical field [0001] The invention relates to the design of the transfer and transportation of hot forgings by a robot in a fully automatic forging line, and is especially applied to the field of forging without requiring personnel to participate in the whole process. Fully automated production process with automatic transfer and conveying. Background technique [0002] With the deepening of industrial transfer and the development of my country's high-end equipment manufacturing industry, some domestic forging enterprises have made great progress in forging technology, forging equipment level and forging ability by absorbing imported technology, strengthening R&D cooperation and technology accumulation. The current domestic forging (front axle and crankshaft) production line basically continues the German technology in the 1980s. This technology has the following three defects in full automation: 1) The use of hot die forging hands and conveyor belts for forgings handling ...

AI Technical Summary

Problems solved by technology

At present, the domestic forging (front axle and crankshaft) production line has basically continued the German technology of the 1980s. This technology has the following three defects in terms of full automation: 1) using hot die forging hands and conveyor belts for forging handling and transportation, Among them, the loading and unloading of forgings on the press and the transfer of materials between stations are realized by hot die forging hands, and the transmission of forgings between presses is realized by conveyor belts.

However, the hot die forging hand is a coordinate structure, with low degrees of freedom, inflexible operation, and high failure rate; while the positioning accuracy of the conveyor belt is low, and the forging conveying time is long

Therefore, the forging handling and conveying method using hot die forging hands and conveyor belts has the disadvantages of high failure rate and low production efficiency

2) The signal transmission between devices adopts a point-to-point mode, relying on manual judgment whether to enter the next automatic operation, the degree of full automation is low, and the production efficiency is low

3) Mold cooling and lubrication adopts artificial spraying method, the working environment is harsh, and the product quality is unstable

This technology requires manual participation in the production process, low degree of automation, low production efficiency, high failure rate, and difficulty in improving product quality, which can no longer meet the current market demand.
