Machined metal parts Development is all of this today. In terms of metal parts machining for molding, it has not made much breakthroughs, and basically depends on several traditional ways to support it. It is more at the level of proofing and unrealistic propaganda. It is not wide and commonly applicable to the field of mechanical molding. This has to be said to be a kind of sorrow in the manufacturing industry, and it has not been awkward.
Of course, even if it is a traditional machining metal parts forming method, many people are not really in the chest, and it is more likely to have a half -knowledge (in fact, I am also the level of half a barrel of water). Everyone "forcibly" popular science. Welcome to check the lack of missing. I throw a brick in front, hoping to lead Jin Yuliang's words.
First of all, Machined metal parts is basically divided into two major categories, one is reduced material molding (removal material), and the other is additive molding. So far, the reduction of material molding is still the mainstream method of machining metal parts for molding. Can replace.
01 reduction of materials
There are many types of reducing materials. We are mainly classified based on machined metal parts, because the final reduction method still depends on the means of machine plus, but there is a big difference in the sources of the rough sources of metal parts machining, so the following is the following. Introduction is based on the acquisition of machining metal parts rough.
A. The profile reduction is formed, as shown in the figure below.
(1) Low processing costs, because they are all standard materials, the purchase cost is quite controllable;
(2) The processing cycle is short, and you can get it directly when you go to the material market. Basically, there are stocks;
(3) The quality of the material is good, because it is a standard profile, so it is more reliable in quality control;
(4) Good processing adaptability. As long as you are not afraid of high processing costs, you can basically process most of the shapes you want.
This molding method is also the most common forming method at present. Many mechanical processing plants will prepare a certain base for such raw materials in order to achieve the best in cost control and cycle surplus. At the same time One of the most likely to contact the mechanical processing method of contact with each other. Perhaps your life is to get a few weekly processing processes under the title of a mechanical craft engineer. Although it looks very simple, there is a lot of knowledge. Without the first peeping door.
B. Casting the process reduction processing, as shown in the figure below.
From the figure above, we can see that the rough of the machined metal parts comes from the casting type, but the cast -formed machined metal parts must meet the product applicable design requirements. The processing is basically the same. The difference is that this cast machined metal parts has the following characteristics:
(1) It can be made into a variety of alien machined metal parts, and greatly reduces the amount of reduced material processing;
(2) To minimize the processing cost of machined metal parts, because it can control the processing waste of machined metal parts;
(3) The selection of machined metal parts can be more flexible and has better product adaptability;
(4) There are certain hidden dangers in the uniformity of material, and the removal of cast stress is also very difficult. Many companies even cut corners in these aspects.
(5) The cost of the metal parts machining rough is too high, especially for the manufacture of machined metal parts that cannot be formed in batches.
In fact, machined metal parts casting is a very dangerous job. Once a friend, a friend is a relatively large casting plant. One day the crane hangs a bowl of iron water to cast it. When I came down, the workers below had no bones, and they were not even melted. The friend was frightened and resigned the next day.
Therefore, I rarely visit the casting factory. Even if the company has arrangements, I try not to enter the dangerous area, because I also have shadows. The so -called gentleman is not standing under the critical wall, and I warn myself to stay away.
However, this machined metal parts molding method is a mainstream method that cannot be avoided in the machinery industry, especially the forming of large devices. Basically, this method is used. It is safe and relaxed, but there are still long distances to go.
C. Forging causes type reduction processing, as shown in the figure below.
From the figure above, we can see that the molding of machined metal parts comes from forging. Forging is a very old machined metal parts molding process. The iron is the most primitive method for forging. The ironing was also a little dream of mine. In fact, I have always been very fond of the traditional mechanical processing method. I think that is based on human technology. In fact, the iron hitting iron is very talented. The manufacturer Mo Xie is also a blacksmith, and the founder of the Longquan Sword, Mr. Ou Yezi, is also a blacksmith. When you are a blacksmith to do a certain level, then it is not called a blacksmith. live.
In fact, the forging of modern craftsmanship has begun to achieve automation. About half a year ago, I went to visit a company. I went to a forging workshop to complete the cognition beyond our cognition. The workshop is very clean. It is also commensurate, and all forging processes are transferred and executed through ABB robots. At the same time The profound influence, because the guide told us that the procurement price of the forging equipment is close to one million yuan, what is a heavy asset company, this is probably, in the face of this forging device, any luxury car and luxury homes are weak, it is almost unbearable, it is unbearable. carry.
Forging machined metal parts has the following characteristics:
(1) It can improve the organizational structure and mechanical properties of the machined metal parts. After the metal monetization and crystallization of the metal, the original rough and columnar crystals became thinner and sizes. The uniform equal shaft and crystallization tissue makes the original bias, loose, pores, residue and other compact and welding of the material. The tissue is more closely and improves the plasticity and mechanical properties of the metal;
(2) It can be forged according to the final requirements of the machined metal parts, thereby reducing the reduction of metal parts machining and saving processing costs.
Of course, through the above pictures, we can still see that forging this work is still a dangerous job. If it is a complete manual operation, its risk factor is not under the casting type, so the smart factory based on automation is solved to solve the solution The fundamental direction of this issue, and many companies now have good application cases, we look forward to a better future.
The above three custom machining metal parts forming methods are more typical and universal ways to reduce materials, and they are also the most common ways. What we can contact in enterprises is basically these three methods.
02 Zeng Material Model
Speaking of Zeng Materials formed, then we have to talk about 3D printing technology. This technology has become very popular now, especially in the news media. Many so -called 3D printing products have subverted our cognition once. What 3D 3D? Printing cars, 3D printing pistols, 3D printing products, etc., there is a trend of replacement of reduction of materials. In fact, this road is still far away. From the current point of view It ’s just a good gimmick. Many people make money by selling the future and dreams.
We can learn what processes of 3D printing through the picture below.
My perception of 3D printing basically stays on the impression of the first edition of the sample, because when developing products, it is indeed a product that has been used in 3D printing, but the printing effect is really dare to compliment. Second, it is the printed machined metal parts "lack of arms and legs". In short, none of them were satisfied with me, and I was limited to the printing of plastic parts. Maybe I was ignorant. I am not very optimistic about this technology. Maybe It does not show the potential to make me optimistic, or maybe because the frog at the bottom of the well has no chance to come into contact with those truly high -end 3D printing products.
Asset Metal technology focuses on metal process solutions, which are widely used in toys, electronics, intelligent components, unmanned aircraft and vehicles.
