Chapter 045 The fourth production set a record 2 tacitly
Don't look at Wu Zhong's bet with Yu Dayong in the bet. Pen ~ fun ~ Pavilion www.biquge.info Wu Zhong knows that the intention of doing this is nothing more than to block the mouth of Youyou! As soon as the meeting ended, he led Yu Dayong directly to the forging.
In fact, if you want to complete the task, you really have to dig out your mind! Because the capacity of forging is there. Of course, Wu Zhong also knew the assessment plan for forging, from the formulation process to the preliminary review of the documents, several drafts, and the final documents were also reviewed by Chang Yiming, Yu Dayong discussed with him, and originally wanted to hold a conference to sign the petition, but then it felt inappropriate, after all, it was a probationary period, so there was no room for maneuver in such a large-scale signing. Therefore, when one is five and two is ten, the two of them tacitly act in a double reed play. However, whether the signing is signed, whether the task of 100 tons per month can be completed is very important, but Yu Dayong has no bottom in his heart! What is the bottom number of Wuzhong? Yu Dayong was anxious to understand, and similarly, Wu Zhong was also anxious to strengthen Yu Dayong's confidence.
Along the way, Wu Zhong talked about it and introduced the forging process to Yu Dayong. Wu Zhong's intention is also very clear: we must do our best to let Yu Dayong understand forging and understand forging, so as to give Yu Dayong full confidence. Otherwise, if the forging encounters difficult problems, the general manager hesitates, many departments and many people will not firmly support, such a forging to complete 1200 tons is likely to be like a fool's dream!
Wu Zhong explained the basic knowledge of forging process to Yu Dayong from the beginning.
Forging process is a processing method that uses forging machinery to exert pressure on metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes, including forging and stamping. According to the movement mode of the blank, forging can be divided into open forging, upsetting, extrusion, die forging, closed die forging, and closed upsetting. There are three main types:
One is open forging. The impact force or pressure is used to deform the metal between the upper and lower two iron (anvils) to obtain the required forgings, which are mainly manual forging and mechanical forging.
The second is die forging. Die forging is divided into open die forging and closed die forging. The metal billet is deformed under pressure in the forging die chamber with a certain shape to obtain forgings, which can be divided into cold heading, roll forging, radial forging and extrusion, etc.
The third is closed die forging and closed upsetting forging. Since there is no flash, the utilization rate of the material is high. It is possible to finish complex forgings in one or several processes. Since there is no flash, the force area of the forging is reduced, and the required load is reduced. However, it should be noted that the blank should not be completely restricted, so the volume of the billet should be strictly controlled, the relative position of the forging die should be controlled and the forging should be measured, and efforts should be made to reduce the wear of the forging die.
We are now forging pressing, to be precise, open forging.
Open forging refers to a pressure processing method that applies an external force to the metal blank during forging to produce plastic deformation, so as to obtain a blank or part with a certain size, shape and internal structure. Since the size and shape of the workpiece are guaranteed by the operation technology, open forging requires workers to have a high level of technology. You have also seen the characteristics of free forging: first, it mainly relies on the level of palm tong workers; The second is that the productivity of open forging is low and the machining allowance is large; The third is that the tool is simple and versatile, so it is widely used in forging forgings with simple shapes, forgings produced in small batches, free forging process characteristics, forgings produced with simple tools and forging equipment, suitable for small batches, large forgings, and relatively low equipment requirements.
Yu Dayong was a little more confused when he heard this: Fifth brother, when you say this, I am even more worried: Do you mean that this kind of forging condition equipment can complete the task of producing 1,200 tons a year at all?!
Ay! Wu Zhong hurriedly corrected: Don't worry! These days, I am thinking, free forging will definitely not complete the task, and it is not realistic to get another forging hammer, how to solve the problem of production efficiency? Don't say it, in the past two February, in the end, let me think about the way to make my debut: mainly in the forging die, the combination of our forging hammer and the grinding ring, the test for more than a month, don't you say that the efficiency has been greatly improved!
Different forging methods have different technological processes, among which the process flow of hot die forging is the longest, and the general sequence is: forging billet blanking, forging billet heating; roll forging billet; die forging forming; trimming; Punching; Correction; Intermediate inspection to inspect the size and surface defects of forgings; Heat treatment of forgings to eliminate forging stress and improve metal cutting performance; Cleaning, mainly to remove the surface oxide scale; Correction; Inspection, general forgings should go through appearance and hardness inspection, and important forgings should also go through chemical composition analysis, mechanical properties, residual stress and other inspections and non-destructive testing. Regardless of the normal process links, I will pay attention to Anman research, the most critical core is the forging of the forging roller blank and die forging, and the knowledge here is great. In layman's terms, it can be molded at one time or multiple times. A forming is mainly with a forging hammer (we are an air hammer 250t) many times, repeated forging knocking, according to a 10 pounds of work calculation, a shift can do up to 2 tons, so that a day 2 shifts are more than 4 tons, 25 days a month, at best 100 tons, if you add the time to be fed, overhaul and overhaul, in essence, it is impossible to complete the task. This might be your biggest fear? The production capacity is there, how can the production task of 100 tons/month be completed?!
Yu Dayong smiled slightly when he heard this, Fifth brother, you have completed 180 tons in the past two months, so I have to give you a reward?!
Wu Zhong laughed when he heard this, hey, Mr. Yu, my fifth brother counts, the average monthly is not 100 tons, I will never want any reward!
Oh? Fifth brother is so confident, it means that you have found a good way in the past two months? Don't worry, I also count my words, and I will be rewarded when I reach 100 tons!
Wu Zhong said: I don't know you yet? Young and promising, dare to act, I am afraid that the good scriptures will be crooked by the crooked monk! Let's take their time in the double reed play?!
The two of them looked at each other and laughed tacitly.
After laughing, Yu Dayong said: Fifth brother, you just said that the free hammer is a waste of material, a long time, and low efficiency, why not take other methods to improve efficiency, and can you improve efficiency with some fetal membranes? ------
Before Yu Dayong finished speaking, he attracted Wu Zhong's praise: Okay, I have read the book in the end, and I can understand it at all! Yu Dayong didn't smile at this time, but looked at Wu Zhong squarely, as if to say: Don't hide it from me, if you don't tell any secrets, I can figure it out!
The two of them looked at each other tacitly. In the end, Wu Zhong said that he didn't tell the secret of increasing production? Find out what happens next, and listen to the next chapter.
