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] like 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. like 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 end effe...

Abstract
The invention relates to a robot intelligent free forging drawing-out method. The robot intelligent free forging drawing-out method comprises the steps of 1, carrying out finite element simulation, specifically, according to the technological characteristics of shaft forgings, the characteristics of a robot and equipment parameters, simulating a technological scheme through finite elements, analyzing defects, correcting the technological parameters, and determining a drawing-out technology suitable for robot free forging, wherein the drawing-out technology suitable for robot free forging comprises multi-pass feeding amount, cross section size and rotation angle parameters; 2, carrying out blanking to obtain an original bar in a certain specification; 3, machining a blank, specifically, machining a tool withdrawal groove in the original bar for clamping, positioning and overturning of the robot; 4, carrying out heating, specifically, heating the forgings to a certain temperature according to the heating specification and carrying out heat preservation on the forgings for a period of time; 5, carrying out drawing-out, specifically, carrying out multi-pass drawing-out on a fast forging machine according to the technological parameters determined in the step 1 so as to obtain the final forgings; and 6, carrying out detection, specifically, checking the forgings. According to the robot intelligent free forging drawing-out method, intelligent free forging of the shaft forgings is achieved advantageously, and the forgings with the shape size and the structure performance both meeting the requirements are obtained.
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...
