cast iron lineation plate
- Making Out Surface Plate can be made into the rib type or box type, and its working surface could be rectangle, square or round. Additionally, the working surface are allowed to have V or U-shaped grooves, round holes, slot holes. Etc. A surface plate is a solid, flat plate used as the main horizontal reference plane for precision inspection, marking out (layout), and tooling setup. The surface plate is often used as the baseline for all measurements to the workpiece.
劃線平臺的生產(chǎn)工藝流程基本是:
Technological process of production of Making Out Surface Plate:
一、鑄鐵平板毛坯:按技術(shù)要求制圖紙、按圖紙制作模型、配料、造型、烘干、澆鑄、落沙、清理、檢驗毛坯的各部位;熱處理毛坯,時效處理,其目的是降低鑄件內(nèi)部的應力,防止機械加工后的變形。
鑄鐵平板機械加工:外觀檢驗并劃線、加工、檢驗;
三、鑄鐵平板工件調(diào)平、人工刮研、檢驗科檢驗; 四、鑄鐵平板的外觀處理、噴漆、包裝、入庫。 鑄鐵平板的精度也可以說是鑄鐵平板的平面度:鑄鐵平板一般精度可以分為0級、1級、2級、3級。鑄鐵平板的精度標準在《中華人民共和國機械行業(yè)標準》JB/T 7974—2000里可以查到。選用精度標準時一般根據(jù)使用情況酌情而定。3級精度以上的鑄鐵平板用做檢驗、劃線、裝配等使用,4級精度以下的鑄鐵平板一般用做鉚焊等使用。
1. Rough casting:
Make drawings according to the technical requirements-Making mold as per the drawings-Prepare material-Modelling-Filling sand-drying-casting-Surface cleaning -Casting parts testing.
2. Heat treating and aging treatment, to reduce the internal stress of castings and to prevent it from deform after machining.
3. Rough machining:
Visual Inspection-Marking-Machining -Final inspection and test.
4. Precision finishing:
Leveling -Scraping- Inspection and testing.
5. Final finish:
Painting,-packing -deliver to warehouse.
The accuracy of the Cast Iron Surface Plate refers to the deviation from flatness of the working surface and it shall be classified as Grade 0,1,2,3.
