Litai Technology News: The project of forging automatic production line of a precision forging contains two automatic forging production lines, and its processing links are relatively complex, including intermediate frequency furnace heating, automatic pier rough, automatic cleaning machine, automatic positioning, robot handling, automatic lubrication and cooling, automatic ordering and other production links. The project adopts automatic control technology for processing and processing, supporting robots - a total of 8, the total investment of the project is about 3 million.
In the project, we first encountered a problem is the efficiency problem, in this problem after many debugging tests, whether it is the test stage or the actual operation stage, the rhythm of the automatic processing production line has always been unable to reach the expected set value, and even some machine operation speed is lower than the manual operation speed, resulting in the advantages of the automatic production line can not be fully played.
In order to further clarify the causes of such problems, process personnel and technical personnel conducted a meeting study, after discussion, it was determined that the automatic forging production line processing technology is basically no problem, only the current process can meet the product quality requirements. Therefore, in order to improve the process efficiency, we can only start from two aspects, on the one hand, to improve the equipment and machinery, on the other hand, to optimize the work process, and the mechanical equipment used in the project is not strong in the structure of adjustment, basically there is no large optimization space.
Finally, after discussion by electrical engineers and programming technicians, it is found that the operation speed of the first robot in each of the four robots in the forging automation production line of the project is too fast, which leads to the operation frequency of the following robots cannot match it, and there is a large process deviation in the middle, so the overall forging efficiency cannot be reliably guaranteed. The work content of the first robot in this project is mainly to perform the rough process operation, the specific process is as follows: the robot catches the product, puts it in the punch press, and then loosens it to return to the original position, the product in the lathe after a forging, the robot then goes in to clip out the forged product and put it in the next station to continue processing. There is no problem with this process, but if compared with the manual operation mode, it can be found that when the human is switching the work section, it will carry out subjective prediction in advance, so as to realize the seamless docking between the two processes, while the robot operation is carried out through the program instructions, and each step is in accordance with the process, so there will be some accumulated time difference between the work sections.
The attribute of the robot to be operated step by step by program control cannot be changed, so for optimization, we can consider whether part of the process can be simplified and unnecessary steps can be omitted, so as to improve the efficiency of robot operation. For example, in the original robot operation process, the robot has to repeatedly grab the forging product from the punch, and the two actions will inevitably waste time, and if the robot first sends the product into the punch, the griper waits directly in place, and waits until the forging is completed and grabs it directly, which will save the time in the middle and back. There is no conflict between the existence of the robot and the forging press station, so this optimization idea is theoretically feasible. After repeated field mapping simulation by mechanical engineers and programmers, the project also fully confirmed that this optimization method can be realized. Finally, through the change of robot operation and the fine tuning of the mold supporting process, the forging production line beat was accelerated by one-third, and the effect was very significant.
