鑄鐵平臺生產(chǎn)的精度有幾種

時間：2015/12/28 13:22:10 瀏覽量：370 鑄鐵平板和（鑄鐵平臺）工作面不得有嚴(yán)重影響外觀和使用性能的砂孔、氣孔、裂紋、夾渣、縮松、劃痕、碰傷、繡點等缺陷。
鑄鐵平板和鑄鐵平臺的鑄造表面應(yīng)清楚型砂且平整，涂漆牢固。
鑄鐵平板和鑄鐵平臺的精度等級為0級3級的平板工作面上，直徑小于15mm的砂孔允許用相同材料堵塞，其硬度應(yīng)小于周圍材料的硬度。工作面堵塞的砂孔應(yīng)不多于4個，且砂孔之間的距離應(yīng)不小于80mm。
鑄鐵平板和鑄鐵平臺應(yīng)采用優(yōu)質(zhì)細(xì)密的灰口鑄鐵等材料制造，其工作面硬度應(yīng)為170220HB。
鑄鐵平板和鑄鐵平臺的工作面通常采用刮削工藝。對采用刮削加工的3級平板工作面，其表面粗糙度Ra最大允許值為5m。
鑄鐵平板和鑄鐵平臺應(yīng)去磁和穩(wěn)定性處理。

鑄鐵平板和鑄鐵平臺相對兩個側(cè)面上，應(yīng)有安裝手柄或吊環(huán)裝置的螺紋孔（或圓柱孔）,且裝置位置的設(shè)計應(yīng)盡量減少因搬運而引起的變形。若鑄鐵平板工作面上設(shè)置螺紋孔（或溝槽），其部位應(yīng)不高于工作面。

Cast iron plates and (cast iron platforms) working surfaces shall not have defects such as sand holes, pores, cracks, slag inclusions, shrinkage, scratches, bumps, and embroidering points that seriously affect the appearance and performance.
The cast surface of the cast iron plate and cast iron platform should be clear and smooth and painted firmly.
The cast iron plate and the cast iron platform have a precision level of 0 and 3 on the flat work surface. Sand holes with a diameter of less than 15 mm are allowed to be blocked with the same material, and the hardness should be less than the hardness of the surrounding material. There should be no more than 4 sand holes in the working face, and the distance between the sand holes should be no less than 80mm.
Cast iron plates and cast iron platforms should be made of high-quality fine gray cast iron and other materials, and the working surface hardness should be 170220HB.
The working faces of cast iron plates and cast iron platforms are usually scraped. For the 3-stage flat working surface using the scraping process, the maximum allowable surface roughness Ra is 5 m.
Cast iron plates and cast iron platforms should be demagnetized and stabilized.

On the opposite sides of the cast iron plate and the cast iron platform, there should be a threaded hole (or cylindrical hole) for mounting the handle or the lifting device, and the position of the device should be designed to minimize deformation caused by handling. If a threaded hole (or groove) is provided on the working surface of the cast iron plate, its position should not be higher than the working surface.
