貴州鑄造公司

Talk about the principles of the choice of the Foundry Company methods in Guizhou:

1.優先采用砂型鑄造 據統計,我國或是國際上,在全部鑄件產量中,60~70%的鑄件是用砂型生產的,而且其中70%左右是用粘土砂型生產的。主要原因是砂型鑄造較之其它鑄造方法成本低、生產工藝簡單、生產周期短。所以象汽車的發動機氣缸體、氣缸蓋、曲軸等鑄件都是用粘土濕型砂工藝生產的。當濕型不能滿足要求時再考慮使用粘土砂表干砂型、干砂型或其它砂型。粘土濕型砂鑄造的鑄件重量可從幾公斤直到幾十公斤,而粘土干型生產的鑄件可重達幾十噸。

The 1. priority is sand casting. According to statistics, in China or internationally, 60 to 70% of the castings are produced by sand mold, and about 70% of them are made of clay sand. The main reason is that sand casting is less cost than other casting methods, simple production process and short production cycle. So the engine cylinder body, cylinder head, crankshaft and other castings are produced by the clay wet molding process. When the wet type can not meet the requirements, the use of clay sand table dry sand type, dry sand type or other sand type can be considered. The weight of the clay wet molding sand can be weighed from several kilograms to dozens of kilograms, while the castings produced by the clay dry type can weigh up to dozens of tons.

一般來講,對于中、大型鑄件,鑄鐵件可以用樹脂自硬砂型、鑄鋼件可以用水玻璃砂型來生產,可以獲得尺寸精確、表面光潔的鑄件,但成本較高。

Generally speaking, for medium or large castings, iron castings can be made of resin bonded sand mold and steel castings, and can be produced by water glass sand mold. The castings with accurate size and smooth surface can be obtained, but the cost is high.

當然,砂型鑄造生產的鑄件精度、表面光潔度、材質的密度和金相組織、機械性能等方面往往較差,所以當鑄件的這些性能要求更高時,應該采用其它鑄造方法,例如熔模(失臘)鑄造、壓鑄、低壓鑄造等等。

Of course, sand casting casting precision, surface roughness, density and microstructure, mechanical properties and material production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting etc..

2.鑄造方法應和生產批量相適應 例如砂型鑄造,大量生產的工廠應創造條件采用技術先進的造型、造芯方法。老式的震擊式或震壓式造型機生產線生產率不夠高,工人勞動強度大,噪聲大,不適應大量生產的要求,應逐步加以改造。對于小型鑄件,可以采用水平分型或垂直分型的無箱高壓造型機生產線、實型造型生產效率又高,占地面積也少;對于中件可選用各種有箱高壓造型機生產線、氣沖造型線,以適應快速、高精度造型生產線的要求,造芯方法可選用:冷芯盒、熱芯盒、殼芯等高效制芯方法。中等批量的大型鑄件可以考慮應用樹脂自硬砂造型和造芯。單件小批生產的重型鑄件,手工造型仍是重要的方法,手工造型能適應各種復雜的要求比較靈活,不要求很多工藝裝備??梢詰盟A靶?、VRH法水玻璃砂型、有機酯水玻璃自硬砂型、粘土干型、樹脂自硬砂型及水泥砂型等;對于單件生產的重型鑄件,采用地坑造型法成本低,投產快。批量生產或長期生產的定型產品采用多箱造型、劈箱造型法比較適宜,雖然模具、砂箱等開始投資高,但可從節約造型工時、提高產品質量方面得到補償。低壓鑄造、壓鑄、離心鑄造等鑄造方法,因設備和模具的價格昂貴,所以只適合批量生產。

2. the casting method should be adapted to the production batch, for example, sand casting. A large number of factories should create conditions for the use of advanced molding and core making methods. The production line of the old jolt or jolt molding machine is not high enough, and the workers are labor intensive and noisy. They are not suitable for mass production. They should be reformed gradually. Can be used for small castings, horizontal type or vertical type of production line, high pressure molding machine box real molding production and has high efficiency, covers an area of less; for parts with various box production line, high pressure molding machine air impact molding line, in order to adapt to the rapid and high precision molding production line requirements methods: core making, cold box, hot box, shell core, core making method. Medium size large castings can be considered with the application of resin self - hardened sand molding and core making. Manual casting is still an important method for heavy duty castings produced by single piece and small batch. Manual sculpt can adapt to all kinds of complex requirements and is flexible, and does not require many process equipment. Can Application of water glass sand, VRH water glass sand and organic ester water glass sand, clay, dry type resin self hardening sand and cement sand; heavy castings for a single production, the pit molding method is low cost, fast production. The multi product modeling or split box modeling method is more suitable for batch production or long-term production of stereotyped products. Although moulds and sand boxes start high investment, they can be compensated from saving molding hours and improving product quality. Low pressure casting, die-casting, centrifugal casting, and other casting methods, because of the high price of equipment and mold, so it is only suitable for mass production.

3.造型方法應適合工廠條件 例如同樣是生產大型機床床身等鑄件,一般采用組芯造型法,不制作模樣和砂箱,在地坑中組芯;而另外的工廠則采用砂箱造型法,制作模樣。不同的企業生產條件(包括設備、場地、員工素質等)、生產習慣、所積累的經驗各不一樣,應該根據這些條件考慮適合做什么產品和不適合(或不能)做什么產品。

3. other methods should be suitable for conditions such as the same factory is the production of large machine tool castings, generally uses the method of cores modelling, do not make the appearance and sand box, in the pit of cores; and another factory used the sand box modelling method, and making the appearance. Different enterprises' production conditions (including equipment, site, staff quality, etc.), production habits and experience accumulated are different. We should consider what products are suitable and what products are not suitable for (or can not) do according to these conditions.

4.要兼顧鑄件的精度要求和成本 各種鑄造方法所獲得的鑄件精度不同,初投資和生產率也不一致,最終的經濟效益也有差異。因此,要做到多、快、好、省,就應當兼顧到各個方面。應對所選用的鑄造方法進行初步的成本估算,以確定經濟效益高又能保證鑄件要求的鑄造方法。

4., we must take into account the accuracy and cost of castings. The accuracy of castings obtained by various casting methods is different. Initial investment and productivity are also inconsistent, and the final economic benefits are also different. Therefore, to achieve more, faster, better, and provincial, we should take into account all aspects. A preliminary cost estimate should be made to determine the casting method selected to determine the casting method that has high economic efficiency and can guarantee the requirements of the casting.
