Process control

1、用于Steel formworkThe steel produced must meet the steel variety specifications required for the steel template construction drawings, and the steel material must meet the national standard ordinary carbon steel Q235a。

2, the face of the material used for the steel die panel must be flat surface smooth without damage and deformation, and the thickness error of the whole surface sheet material is within the national standard range。

3, for steelTemplate processingThe working panel of the board is strictly prohibited from using board surface rust (pit pitting), pitting or sub-board with the missing corner and missing edge of the washboard (cutting board tearing)。

4, the composite rib Angle steel channel steel and other steel must be straight without deformation (deformation dead bending), the main stress of the rib must be selected for the whole, for the special-shaped corner arc and other parts that can not use the whole material must be strictly operated。

5. The welding shrinkage amount should be reserved for the parts with large welding amount and the parts with large welding amount when the steel die is discharged and cut。The composite assembly and processing of the steel template should be processed according to the given size modulus of the drawing, the coordinate size of the center hole is accurate, and the combination accuracy of the steel template and the exchange accuracy of the assembly process must be ensured。

Combination welding

1, mold fan production;It must be constructed on a certain rigid mold, and the stereotyped rib assembly welding -- rib correction detection -- skeleton assembly positioning welding -- group to panel welding and welding molding。

2, the steel formwork must be constructed on the mold, for the bolt holes used in the combination assembly, the bolts should be tightened in advance during the combination assembly to prevent the size dislocation of the bolt holes or other adjacent parts during assembly。

3, the steel template rib skeleton mesh reinforcement welding can be welded under the mold, rib skeleton mesh reinforcement welding must be corrected after the mold combination steel mold panel。

4. The tire on the steel die panel must be corrected and trimmed, the combination rib skeleton mesh is fixed in position, and the panel and rib edge of the rib plate are pressed and welded smoothly。The steel mold skeleton mesh and the panel are welded by symmetrical spacing welding。
