1. The design drawings provided by the architectural design institute can not be directly used to process the color steel plate, but should be drawn on the basis of the original design drawing after considering the processing technology, such as tolerance
matching, processing allowance, welding control and other factors. Processing drawing is the ultimate communication between the designer and the builder's intention. It plays the role of making the essentials book. It is also the instructions for
actual size, marking, shearing, groove processing, punching, bending, assembling, welding, painting, product inspection, stacking, sending and other operations. It also plays a high level of management. The role of checklists.
2. Analysis of Construction Conditions before Processing and Manufacturing
Drawing processing drawings or reviewing design drawings should analyze construction conditions or degree of difficulty while examining them. It is necessary to carefully analyze the difficult parts of welding, whether to use high-strength bolts and fasteners, and whether to maintain the welding angle of electrodes in narrow places
3. Steel tape? In color steel sheet engineering, tape, broadband steel tape and convex steel tape are mainly used in any one of the first-class products. It is better to make the factory tape and the field tape belong to the same kind of products, that is, to use "the same ruler" between different types of work. If there are difficulties, the difference between 10m is controlled within 0.5mm.
4. On-the-job operators should be trained and assessed, special types of work should be qualified, and the technical submission of various processes should be fully completed.
Lofting is the process of drawing the solid shape of the product or parts on the lofting table or flat plate according to the shape and size required by the detailed construction drawings or parts drawings of the colored steel plate products, and drawing the solid shape of the products or parts on the lofting table or flat plate according to the ratio of 1:1, so as to obtain the real length and make the template. For more complex shell parts, it is necessary to draw and expand.
