Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0028] Such as figure 1 , figure 2 As shown, the traditional manual elongation process relies on the experience of the process planners, and the process parameters are difficult to guarantee. In addition, the process parameters of the traditional manual forging need to be recorded manually, and it is difficult to monitor the temperature and shape of the forging in real time. Defects such as cracks cause problems such as poor product consistency and low pass rate. Such as figure 1 Forgings with axis bending defects shown, figure 2 Forgings with surface crack defects shown.

[0029] combine Figure 3-Figure 11 Explain, a kind of robot intelligent free forging drawing length method that can be suitable for shaft forging, it comprises the following steps:

[0030] 1. Finite element simulation. The robot en...

Abstract

A robot intelligent free forging and drawing method, which includes: 1. Finite element simulation, according to the process characteristics of shaft forgings, robot characteristics, and equipment parameters, simulate the process plan through finite elements, analyze defects, correct process parameters, Determine the elongation process suitable for robot free forging; the elongation process suitable for robot free forging includes multi-pass feed, cross-sectional size and rotation angle parameters; 2. Cutting the material to obtain the original bar of a certain specification; 3. Billet processing, machining the relief groove on the original bar for robot clamping, positioning and flipping; 4. Heating, heating the forging to a certain temperature according to the heating specification and keeping it warm for a period of time; 5. Pulling out, according to the steps Once the process parameters are determined, multi-pass drawing is carried out on the fast forging machine to obtain the final forging; 6. Inspection, forging inspection. The invention is helpful to realize the intelligent free forging of the shaft forgings, and obtain the forgings whose shape, size and structure performance meet the requirements.

Description

technical field [0001] The invention relates to the field of intelligent forging, in particular to a robot intelligent free forging and drawing method. Background technique [0002] Forgings play a very important role in the research and development of advanced weaponry and equipment. Most of the key stress-bearing components such as engines, airframes, and projectiles in advanced weaponry such as aviation, aerospace, ships, and weapons are manufactured by forging technology, and these The precise control degree of the shape, size and structure performance of key forgings directly affects various important indicators such as weapon equipment performance, structural weight coefficient, striking accuracy, reliability, manufacturing cost and lifespan. At present, my country's forging production ranks first in the world and has become a world forging power. However, most domestic forgings are produced manually. The quality of forgings is unstable, the production efficiency is l...
