  • 怎样判定自己对制造的了解程度?
  • 本站编辑:杭州思良塑料模具有限公司发布日期:2020-03-12 09:49 浏览次数:

最简单的方法是随手抓一张自己设计的东西的图纸你是否能说出它的制造全过。铸、锻、车、钳、铣、刨、磨,只是这样子,肯定是不行,在机械厂做过几年的谁不知道?必须细分下去,要全面了解各过程。比如说铸造时候怎么分型,浇口冒口怎么放,可能会有什么样的铸造缺陷产生,零件结构在热处理的时候会不会导致意外情况发生的,怎么在零件结构上进行优化,切削加工过程,在脑海中虚拟出来,总共用几把刀,转速,走刀量,甚至铁屑往哪里飞,各把刀使用的顺序,车工,铣工,磨工的操作动作全过程,如此等等,才算是有了比较好的基础。


  不是说搞设计的一定要会玩车床,铣床,会烧电焊才可以,但是要知道这些作业特点,在设计时加以充分考虑,作为搞机械设计的人这样才比摇车床烧电焊的强,才有安身立命之处。如此,在设计过程中,就会规避一些不合理的结构,设计的质量自然提高不少,可是还不够,一个有十年八年的工龄的技工能提出比你更成熟的细节方案(尽管整体的设计统筹他们做不了),但是多少个不眠的夜晚设计出就这样一个结果,岂不是斯文扫地耶?唯一的解决办法,多看书。别人总结出来的通常与生产相结合,俱是心血的结晶。带着问题学,多想就能消化。再也不会说“只要保证同心度就行了”这样愚蠢的回答,关键是你已经指出保证同心度的方法,甚至前辈的错误。这个时候,没人再叫你小钱、小赵,连老板都叫你钱工、赵工,挺受尊敬的吧。摸摸下巴,胡子长出来了,尿布丢了,孩子叫妈了,呵呵成就感也来了。


  可是设计总是为了使用,好的设计必须具备一点点人性的,设计一套工艺装备,一试产,效率高质量好,老板来搞杯庆功酒。过了几天,发现人家弃之不用了,原因是操作者骂娘啊。用起来痛苦啊。而且要注意的细节又多,别人就是个操作工他要是考虑的那么多因素就不会还在那里做操作工了啊。设计不利于使用,就面临淘汰,有很多的成套设备,如汽车的发动机变速箱之类正常运转时“挺好的“,可其中一个小键槽,一个轴承位,什么的地方坏了,整个就不能用,厂方只卖整件,要配件不卖,自己加强还真的没地方加了,换了几个厂去买,摆了一堆,用户只好敬而远之,立了个技改项目——可怜的技改。这样的事情只要是在机械行业转的久的都会有所见所闻。使用根本就离不开维修,好的设计更不能忽视维修性。在一条大型的的生产线上,关键的设备,总共一年也就维修那么两次,但是每次都要把设备大卸八块,行车叉车千斤顶撬杠十八般兵器还不够用,老师傅们还要自己专门动脑动手玩几样好用的专用家当来伺候,导致停产的损失已经超过设备本身的价值,真是个无言的结局。一套大型设备仅因更换一只油封什么的,都要几乎将整机完全分解,使用单位不骂设计干的是断子绝孙的玩意才怪,真的是设计者的悲哀。

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.
