The rare earth is not thin, why the price per ton rises by more than 10 million yuan in one month! Yesterday, Wang Caifeng, deputy inspector of the Raw Materials Division of the former Ministry of Industry and Information Technology and head of the preparation group of the China Rare Earth Industry Association, told the Morning Post reporter that he said farewell to the "rabbit price" to the upstream rare earth enterprises, but to the downstream enterprises. When it rises to a certain degree, there should be normal convergence. At present, the single oxide rare earth oxide with a purity of ≥99.99% has reached 19 million yuan/ton, which is already more than twice the price of silver. The price of the product in the first half of May was only 8.2 million yuan / ton, an increase of more than 10 million yuan / ton in just 1 month. In addition, antimony oxide and antimony oxide also had a one-fold increase. Yesterday, Zhejiang, a well-known lighting company procurement head said that as a rare earth downstream users, energy-saving lamps with rare earth trichromatic phosphor prices are almost changing every day, and it is difficult to buy, there are many lighting companies in Zhejiang have stopped producing fluorescent lamps. RE value return? Rare earth is a strategic resource and is widely used in various fields of national economy and defense industry. In recent years, China has begun to strengthen the regulation and control of the rare earth industry, but it has suffered criticism from countries such as Japan and the United States. Synchronized with the "protested" is that the price of rare earth varies from 1 to 6 times in half a year. Relative to the heavy rare earth in the south, the price of light rare earth in northern China rose slightly. According to the quote of the Baotou Rare Earth Enterprise Confederation (Alliance) on June 4, the price of antimony oxide was 169,000 - 17 thousand yuan per ton and the price of antimony oxide was 219,000 - 22 million per ton. Compared with April 29, the quotation rose by nearly 40,000-50,000 yuan/ton. For the rare earth price is not a "value return", a large-scale rare earth smelting and separation business in Zhangzhou, said that this is the market "buy and sell" the formation of rare earth prices out of the "cabbage price" nothing bad. On May 19, the State Council stated in its "Several Opinions on Promoting the Sustainable and Healthy Development of the Rare Earth Industry" that reforming the price formation mechanism of rare earth products, intensifying policy control, and gradually realizing the unity of rare earth values ​​and prices. Xue Xuefeng, an analyst at CITIC Securities, wrote a research report on the 13th. Although in the past China’s rare earth was sold for a long time, the main reason for the continuous rise of rare earths since the beginning of this year was policy control rather than a real return to value, middlemen and rare earths. The company's stock and speculation make current rare earth prices have a certain "bubble." Prices soared "injury industry chain" From the price of “cabbage†to “silver price,†rare earth also caused damage to the domestic industrial chain. Yesterday, a senior source of a large rare earth smelting and separation company in Zhangzhou said that despite the high price of rare earth, many traders are still reluctant to ship. Yesterday, the above-mentioned person in charge of the procurement department of Zhejiang Lighting Company stated that fluorescent lamp companies need to add rare earth raw materials, and many small businesses cannot support the cost pressure and can only stop production. According to "Economic Information Daily" reported yesterday, Minmetals Donglin Lighting (Jiangxi) Co., Ltd., a general manager, said that due to the current tight supply of phosphors, many companies have been suspended, the impact of the second half for the entire industry will be gradually reflected. “Many companies in Ganzhou have increased their sales revenue, and the market is not entirely a state of “having price and no marketâ€.†According to the person in charge of the above-mentioned Zhuzhou rare earth smelting and separation company, there are some companies in Zhangzhou that are “for money†only. , And some companies only ship to high-end customers, resulting in a lot of downstream small business raw materials "out of stock." Wang Caifeng also stated that there are downstream companies that have accumulated rare earth raw materials. If the materials are made into lights, it may not be profitable, and the profits from selling rare earth raw materials are very high. This phenomenon is not sustainable. “Although phosphors are very important, NdFeB is the main material that drives the development of the entire rare-earth industry chain.†Wang Caifeng said that rare-earth output mainly fluctuates around Nd-Fe-B materials, and if there is no Nd-Fe-B material industry, rare earths produce more Less production does not matter at all. Wang Caifeng also said that the amount of rare earths used in fluorescent lamps and hydrogen storage materials is currently declining. With the advancement of technology, many materials have been continuously replaced, but there is currently no substitute for neodymium-iron-boron materials. Wang Caifeng said yesterday that many NdFeB companies that participated in the National Rare Earth Conference in Beijing (held on 13 and 14th in Beijing) recently complained to them that the price of rare earths rose too fast, causing NdFeB materials to increase in price. Although the current day is not yet a “opening potâ€, if it is still “available without price†in the next years, it will definitely cause great damage to the rare earth industry.

10. Assembly. The so-called assembly is to group multiple parts or components together in a certain way to make them into a complete material. One thing that needs to be paid attention to is the protection of the materials, and no scratches. Assembly is the last step in the completion of a material. If the material cannot be used due to scratches, it needs to be reworked and reworked, which will waste a lot of processing man-hours and increase The cost of the item. So pay special attention to the protection of the item.

1. Design and draw the part drawing of its sheet metal parts, also known as three views. Its function is to express the structure of its sheet metal parts by means of drawings.
2. Draw an unfolded drawing. That is, unfold a part with a complicated structure into a flat piece.
3. Unloading. There are many ways to unload, mainly the following methods:
a. Shearing machine cuts the material. It uses the shearing machine to cut out the length and width dimensions of the expanded drawing. If there are punching and corner cutting, then the punching machine is combined with the die to punch and corner to form.
b. Punch blanking. It is the use of a punch to punch the structure of the flat part after the parts are unfolded on the plate in one or more steps. Its advantages are short labor hours, high efficiency, and can reduce processing costs. It is often used in mass production.
c. NC CNC blanking. When NC blanking, you must first write a Cnc Machining program. That is, use the programming software to write the drawn expanded diagram into a program that can be recognized by the NC CNC machining machine. Let it follow these programs step by step on a piece of iron plate On the top,punch out the structural shape of its flat parts.
d. Laser cutting is the use of laser cutting to cut the structure and shape of the flat piece on an iron plate.
4. Flanging and tapping. Flanging is also called hole extraction, which is to draw a slightly larger hole on a smaller base hole, and then tap the hole. This can increase its strength and avoid slippage. Generally used for sheet metal processing with relatively thin plate thickness. When the plate thickness is large, such as the plate thickness of 2.0, 2.5, etc., we can tap directly without flanging.
5. Punch processing. Generally, punch processing includes punching and cutting corners, punching blanking, punching convex hull, punching and tearing, punching and other processing methods to achieve processing purposes. Its processing requires corresponding molds to complete the operation. There are convex molds for punching convex hulls, and tearing forming molds for punching and tearing.
6. Pressure riveting. As far as our factory is concerned, pressure riveting studs, pressure riveting nuts, pressure riveting screws, etc. are often used. The pressure riveting method is generally completed by a punch or hydraulic pressure riveting machine. Riveted to the sheet metal part.
7. Bending. Bending is to fold 2D flat parts into 3D parts. Its processing requires a folding bed and corresponding bending molds to complete the operation. It also has a certain bending sequence, and the principle is to make the next cut The first fold that does not cause interference will produce the interference back fold.
8. Welding. Welding is the group welding of multiple parts together to achieve the purpose of processing or the edge welding of a single part to increase its strength. The processing parties generally include the following: CO2 gas shielded welding, argon arc welding, Spot welding, robot welding, etc. The selection of these welding methods is based on actual requirements and materials. Generally speaking, CO2 gas shielded welding is used for iron plate welding; argon arc welding is used for aluminum plate welding; robot welding is mainly in-material It is used when the parts are large and the welding seam is long. Such as cabinet welding, robot welding can be used, which can save a lot of tasks and improve work efficiency and welding quality.
9. Surface treatment. Surface treatment generally includes phosphating film, electroplating colorful zinc, chromate, baking varnish, oxidation, etc. Phosphating film is generally used for cold-rolled plates and electrolytic plates, and its function is mainly to plate on the surface of the material. A protective film is applied to prevent oxidation; the second is to enhance the adhesion of its baking paint. Electroplated multicolored zinc is generally treated with cold-rolled plate surface treatment; chromate and oxidation are generally used for surface treatment of aluminum plates and aluminum profiles; its specific surface The choice of treatment method is based on the customer's requirements.
