If you want to do a good job of metal stamping parts, you need to pay attention to the early stage

The design of metal stamping parts die is the front-end content of the industry. When the designer gets the product drawing, the first thing is to evaluate the parts, combine the product tolerance level, and determine the process and characteristics. The designer sorted out the evaluation content of the product before opening the mold, and the details are as follows: 1. Product drawing confirmation 1. Frame: Confirm the part name, version, angle of view, material, thickness, etc. in the frame of the metal stamping parts. The content of the annotations of the drawings must be confirmed one by one. 2. Check the integrity of the view: the view is complete, the content is clear, and the dimensions are correct and complete. 3. Key identification and confirmation of special requirements: such as embossing, height, indicating treatment, lines, burrs, and key size control. 4. Confirm whether the size of the drawing file is consistent with the marked size on the drawing. If there is no standard size, please refer to the drawing file. If there is a rivet process, determine whether there is a physical or electronic file for reference. For the sprouting process, confirm its purpose and confirm the control size. 5. If the product cannot be formed due to the bending edge, whether it is possible to open a 1x1 process gap or process groove. 6. Confirm whether the parts have appearance requirements, flatness requirements, color requirements, etc. 7. The part has a half-cut process, confirm whether the half-cut height or the half-cut position size is guaranteed. 8. Focus on confirming the output size of the part mold opening, which is used as the basis for determining the mold type. 9. When the bending product is unfolded, whether the corner design can be clear for the case of small inner R. 10. If the hole is close to the forming position, is it acceptable when there is deformation or position deviation? 11. When determining that the part is a continuous mold, whether there are special requirements for the position of the product stripping point and the shape of the knife edge. 12. The key content of the ECN column needs to be confirmed. 2. The key confirmation of the part drawing. 1. Confirm whether the marked dimensions of the metal stamping parts are consistent with the actual 3D dimensions provided. 2. Whether the ECN content has been modified.
