What should be paid attention to when layout of stamping die workpiece?

With the development of society, stamping parts have been popularized in various fields. To produce high-quality stamping products, the layout of stamping die workpieces is also very important. So what problems should be paid attention to when the workpiece layout is in the stamping process? Let's take a look at it below; workpiece layout refers to the layout and cutting method of workpieces that need to be cut on the sheet. How to choose a reasonable layout is an effective measure to improve material utilization, reduce production costs and ensure the quality of workpieces. Layout initially refers to the arrangement of blanking parts on strips, strips, and sheets. Choosing a reasonable layout method and appropriate edge value is an effective measure to improve material utilization, reduce production costs, and ensure the quality of workpieces and the life of molds. 1. According to the layout of the blanking parts on the sheet, the layout forms are: 　1, straight row 2, single row row 3, multi-row row 4, diagonal row 5, opposite straight row 6, opposite opposite diagonal row, etc. 2. Workpiece Layout is an important part of stamping workpiece and die design. The following points should be paid attention to when layout: 1. When layout, accurate and reliable positioning should be fully considered, and special attention should be paid to the distribution and diameter of guide pins. 2. When layout, pay attention to the grain direction of the material, avoid the grain direction being parallel to the bending line, and make it perpendicular to the bending line as much as possible. 3. When the position accuracy of the hole and the shape is high, it should be punched out in adjacent steps as much as possible. 4. Holes with high relative position accuracy requirements should be punched out in the same step as much as possible; 5. The arrangement of bending forming parts should consider factors such as easy feeding and non-deformation. 6. When the bending does not meet the requirements of the workpiece, two bendings can be used or the shaping station can be added; for two right-angle bendings, in order to avoid the deepening of the material, first bend 45° and then 90° bend. 7. When the cutting edge distance is too close, it should be set as an empty step to improve the strength of the mold. 8. Mold manufacturing and mold processing should be considered when layout. 9. For a complex hole, it should be broken down into a number of simple holes for step-by-step punching, but when disassembling, pay attention to a good connection between the front and rear punching times. 10. When it is foreseeable that the workpiece is difficult to meet the design requirements, there should be room for mold modification. 11. When the stamping conditions are met, the material utilization rate should be maximized as much as possible. The step distance of the material, and the width of the material takes an integer. 12. When forming, the flow of material should be fully considered. Under normal circumstances, it should be ensured that the strip is not deformed or less deformed during the forming process, so sometimes the process incision will be appropriately increased. 13. The design of the punch shape should consider various factors such as the strength of the die, the strength of the punch, the fixation of the punch, and the processing of the punch. 14. Bending should consider the resignation of the subsequent process, the sequence of various bending, the strength of the mold, and whether the feeding is smooth. 15. In order to make the material feed stably during the stamping process, a carrier must be set in the layout, and the workpiece and the material must be connected at the joint. The carrier is generally set on both sides, middle or one side of the material, and the size of the carrier It must have sufficient strength and save materials. The carrier with guide holes can correct the movement in the high-speed stamping process. The location of the connection should be selected appropriately, not only stable and reliable, but also conducive to the cutting of other stations and the final station, and separation from the carrier.
