2021年MFC第二屆金屬冷擠與精沖技術論壇暨供需配對交流會

2021 MFC 2nd Metal Cold Extrusion and Fine Blanking Technology Forum and Supply and Demand Matching Exchange Meeting

2021年5月13-14日，帕爾弗參加了MFC第二屆金屬冷擠壓與精沖技術論壇暨供需配對交流會。會議由《金屬板材成形》雜志于上海青浦舉辦，規模約150人。

On May 13-14, 2021, Porfu participated in the 2nd MFC Metal Cold Extrusion and Fine Blanking Technology Forum and Supply and Demand Matching Exchange Meeting. The conference was organized by "Sheet Metal Forming" magazine in Qingpu, Shanghai, with a scale of about 150 people.

冷擠壓（包括冷鍛、冷鐓）是一種高效、優質、低耗、附加值高的先進金屬體積凈成形工藝，多應用于5公斤以下的精密體積件中，部分替代了切削、粉末冶金、鑄造、熱鍛等工藝，在歐美日系乘用車單車的冷鍛件使用超過40公斤以上，在中國汽車上的應用空間還很廣。

Cold extrusion (including cold forging and cold heading) is a high-efficiency, high-quality, low-consumption, and high-value-added advanced metal volume net forming process. It is mostly used in precision volume parts under 5 kg, partially replacing cutting and powder Metallurgy, casting, hot forging and other processes are used in cold forgings of passenger car bicycles in Europe, America and Japan over 40 kilograms, and there is still a wide range of applications in Chinese automobiles.

對優質模具合金鋼、精確下料、模具設計和制造、坯料潤滑、自動化設備、鍛后處理、成形設備等因素有著很高的要求，具有生產效率高、不需要加熱，也不需要去氧化皮，材料利用率高，減少二次加工的工序和加工的廢料的量、成型件一致性好，尺寸精度好、工件機械性能高，表面質量好，擁有更大的強度重量比和連續的晶粒流向等優點。 精沖是一種技術含量高的板材沖壓技術，用來生產尺寸較小、負荷較大、精度高的沖壓件，乘用車、商用車、摩托車、工程機械和農機上的常見精沖件大約有300多種，在中國的應用一直在持續增長。

It has high requirements for high-quality die alloy steel, precise blanking, die design and manufacturing, blank lubrication, automation equipment, post-forging processing, forming equipment and other factors. It has high production efficiency, does not require heating, and does not require descaling. , High material utilization rate, reduction of secondary processing procedures and the amount of processed waste, good consistency of molded parts, good dimensional accuracy, high mechanical properties of the workpiece, good surface quality, greater strength-to-weight ratio and continuous grains Flow direction and other advantages. Fine blanking is a high-tech plate stamping technology used to produce stamping parts with smaller dimensions, larger loads and high precision, and common fine blanking parts on passenger cars, commercial vehicles, motorcycles, construction machinery and agricultural machinery There are about 300 kinds, and their applications in China have been growing continuously.

精沖工藝包含了3種力： 沖裁力FG、齒圈力FR、反壓力FS，使得精沖技術區別于其它普通的沖壓或者沖裁工藝。精沖件具備垂直度好、具備無撕裂的光亮切斷面、無須后續加工的眾多優點。精沖件替代了部分的精密鑄件、鍛件、粉末冶金件及機械加工件。另外利用伺服壓力機沖壓或者精密模具在傳統壓力機上沖壓獲得類似于精沖效果的技術也在快速普及。

The fine blanking process includes three types of forces: blanking force FG, ring gear force FR, and back pressure FS, which makes the fine blanking technology different from other ordinary stamping or blanking processes. Fine-blanking parts have many advantages such as good verticality, bright cut surfaces without tearing, and no need for subsequent processing. Precision blanking parts replace part of precision castings, forgings, powder metallurgy parts and machined parts. In addition, the use of servo press stamping or precision die stamping on a traditional press to obtain a fine-blanking effect similar to the technology is also rapidly spreading.

冷擠和精沖都是技術門檻高、附加值高的工藝，有不少融合交叉部分，面對的客戶群也多有重合。華東地區是冷擠壓和精沖企業的集中區，因此，這兩個主題的會議合在蘇州舉辦。

Cold extrusion and fine blanking are both processes with high technical barriers and high added value. There are many integration and intersection parts, and the customer groups they face also overlap. East China is a concentrated area of cold extrusion and fine blanking enterprises. Therefore, these two themed conferences were held in Suzhou.

在2019年的首屆冷擠壓論壇上大約有近30家企業的近50名代表參會，包含國內外前列的材料、壓力機、自動化、潤滑、模具、冷鍛件、下游采購商等全產業鏈的企業和科研院所代表，進行了充分的交流。

At the first Cold Extrusion Forum in 2019, nearly 50 representatives from nearly 30 companies participated in the conference, including the entire industry chain of domestic and foreign first-class materials, presses, automation, lubrication, molds, cold forgings, downstream buyers, etc. The representatives of enterprises and scientific research institutes in the country had full exchanges.

2020年雖然遭遇疫情，但是乘用車、摩托車、電動自行車止跌反彈，新能源汽車發展迅猛，商用車、工程機械延續了多年高速發展的態勢，農用機械低迷五年后在政策帶動下強力反彈。各行各業對冷擠壓、冷鍛、冷鐓、精沖等工藝和零部件的需求很強烈。

Despite the epidemic in 2020, passenger cars, motorcycles, and electric bicycles stopped falling and rebounded. New energy vehicles developed rapidly. Commercial vehicles and construction machinery continued their rapid development for many years. After five years of downturn in agricultural machinery, they were strongly driven by policies. Rebound. There is a strong demand for cold extrusion, cold forging, cold heading, fine blanking and other processes and parts from all walks of life.

本次論壇組織了12場講座，邀請上下游共約150名代表參會，創建線上和線下的人脈圈子，促進上下游及同行的交流，增加采購商與零部件的合作，共同促進金屬成形行業的發展。

The forum organized 12 lectures, inviting about 150 representatives from upstream and downstream to participate in the forum, creating online and offline networks, promoting communication between upstream and downstream and peers, increasing cooperation between buyers and parts, and jointly promoting metal The development of the forming industry.

會議就高效自動化、高附加值、高精度、節能環保、凈成形等主題進行了討論交流，實現了冷擠壓與精沖成形技術探討與企業之間供需采購對接，促進了參會人員企業之間友好交流、共同學習進步發展。

The meeting discussed and exchanged topics such as high-efficiency automation, high value-added, high-precision, energy-saving and environmental protection, net forming, etc., realized the discussion of cold extrusion and fine blanking forming technology and the docking of supply and demand among enterprises, and promoted the participation of participants and enterprises. Friendly exchanges, mutual learning, progress and development.
