Zhongshan Precision Sheet Metal Manufacturer discusses the hazards of raw material deformation in sheet metal processing

　　Zhongshan Precision Sheet Metal Manufacturer: Brief description of the hazards of raw material deformation in sheet metal processing

　　A brief description of the hazards of raw material deformation. In addition to the hazards during sheet metal processing, many raw material selections also pose risks. The deformation defects of sheet metal processing raw materials are mainly caused by unreasonable processes or violations during steel rolling, storage, transportation, and hoisting. Unevenness, bending, and twisting, etc., local deformation defects directly affect the accuracy and quality of layout, marking, and blanking, especially the blanking process. The appearance deformation defects of steel not only affect the accuracy and quality of layout and marking, as well as the processing difficulty of blanking, but also the internal stress of the material will be further released after blanking, leading to further expansion of deformation. The damage caused by processing deformation defects of metal plates is correspondingly greater.

　　 Zhongshan Precision Sheet Metal Manufacturer: Changes in metal plate processing technology

　　Zhongshan Precision Sheet Metal Manufacturer: Traditional sheet metal processing technology is shearing-stamping-bending-welding process or flame plasma cutting-bending-welding process. Facing orders with multiple varieties, small batches, customization, high quality, and short delivery times, it shows obvious unsuitability. Laser cutting technology, as a substitute technology for "cutting-punching", has the characteristics of flexibility and high flexibility. At the same time, most people believe that its cost is high, therefore, it is often used to manufacture workpieces and samples (single pieces or very small batches) with special shapes (or complex shapes). However, as small-batch manufacturing becomes more common, the demand for laser cutting is also increasing.

　　The following examples illustrate the characteristics of the new method.

　　1. Under traditional technology, the workpiece is composed of several parts. Now, it is completed with one cutting and bending, reducing the process, shortening the construction period, and lowering the cost.

　　2. Zhongshan Precision Sheet Metal Manufacturer: Under traditional technology, special jigs are provided for welding. Currently, similar woodworking tenon technology is used between parts, which is accurate in positioning, time-saving, and the welding jig is simple, the product deformation is small, achieving the purpose of shortening the construction period, reducing costs, and improving quality.

　　3. Multiple bending technology has been promoted in the domestic box manufacturing industry. The advantages are that it eliminates the traditional reinforcing ribs, and it has its unique features in design and technology, thus achieving high product quality and low manufacturing costs. In actual technology, it needs to be combined with spot welding.

　　4. Using the characteristics of laser narrow slit and high precision, four workpieces are completed with one cutting (with micro-connection) and four bending, breaking through the design ideas under traditional technology, achieving the purpose of shortening the construction period and reducing costs.

　　5. Zhongshan Precision Sheet Metal Manufacturer: Due to the use of tenon structure, the workpiece can be completed by combining spot welding after bending. The workpiece deformation is small, and no polishing is required before spraying. Due to the characteristics of the new process flow, advanced sheet metal equipment software support and design, laser cutting process and bending process, it supports 2D parts design, pipe parts design, bending workpiece design (only supports Bystronic bending machine) and 3D graphic development, and sends the numerical control program to the specified machine through the standard computer network.
