The easiest way is to grab a blueprint of something you design yourself. Can you tell if it has been made. Casting, forging, turning, tongs, milling, planing, grinding, but this is definitely not the way to go. Who hasn't known for several years in a machinery factory? It must be broken down and the processes must be fully understood. For example, how to type when casting, how to place the gate riser, what kind of casting defects may occur, whether the part structure will cause an unexpected situation during heat treatment, how to optimize the part structure, cutting processing The process is virtualized in my mind. A total of several knives, speed, amount of travel, and even where iron scraps fly, the order of the use of the knives, the entire process of turning, milling, grinding operations, etc. It is considered to have a better foundation.
Not to say that designing must be done with lathes, milling machines, and electric welding, but we must know these operating characteristics and fully consider them during design. As a person who is engaged in mechanical design, this is better than electric lathe welding. There are places to settle down. In this way, in the design process, some unreasonable structures will be avoided, and the quality of the design will naturally improve a lot, but it is not enough. A technician with a working age of ten or eight years can come up with more mature details than you (despite the overall They ca n’t do the design co-ordination), but how many sleepless nights designed such a result, would n’t it be a breeze? The only solution is to read more. What others have summarized is usually combined with production, which is the crystallization of painstaking efforts. With problem learning, you can digest with more thoughts. Never say a stupid answer like "As long as concentricity is guaranteed", the key is that you have already pointed out the method to ensure concentricity, even the mistakes of seniors. At this time, no one calls you Xiaoqian and Xiaozhao, even the boss calls you Qiangong and Zhaogong. It's very respectable. Touching the chin, the beard grew, the diaper was lost, the child called mom, and the sense of accomplishment came.
But the design is always for use. Good design must have a little humanity. Design a set of crafts and equipment, a trial production, high efficiency and high quality. After a few days, I found that people abandoned it because the operator scolded her. It's painful to use. And there are many details to pay attention to. Other people are operators. If he considers so many factors, he will not be an operator there. The design is not conducive to use, and it is facing obsolescence. There are many complete sets of equipment, such as the engine gearbox of a car, which are “good” during normal operation, but one of the small keyways and one bearing is broken. It ca n’t be used, the factory only sells the whole piece, and the accessories are not sold. There is really no place to strengthen it. I changed it to a few factories to buy it and put a bunch of it. The user had to respect it and set up a technical renovation project— Poor technical transformation. Such things will be heard and heard as long as they have been in the machinery industry for a long time. Use is inseparable from maintenance, and good design can not ignore maintenance. In a large production line, the key equipment is repaired twice a year in total, but the equipment must be unloaded eight times each time. The eighteen-type weapon of the forklift jack and crowbar is not enough. Teachers It is also necessary to use your own brains to play with a few special and convenient household appliances to serve. The loss caused by the shutdown has exceeded the value of the device itself, which is a silent end. A large set of equipment just needs to completely disassemble the whole machine just to replace an oil seal or something. It is no wonder that the unit does not scold the design for doing things that are broken off. It is really the sadness of the designer.
