Precision metal stamping parts figure how to draw, please be aware that this several steps
Many fledglings stamping industry friends to learn more knowledge of precision metal stamping parts, the Lao shifu will make its first learn the mould structure and drawing mould expansion plan, the authors also compiled a few steps to our friend reference study. 1. Print a after confirm the correct graph of precision metal stamping parts; 2. Details about the product to confirm material content, understand the product need to improve process. 3. Carefully read the product figure, understand the product structure and technological requirements. 4. Combination of precision metal stamping parts figure 2 d and 3 d electronic archives, understand every detail structure of products, do it with the heart. 5. Precision metal stamping parts corresponding into a new image file, copy a to the beside. 6. Confirm product figure is the first corner of the drawing or third Angle, unit is inch or metric size, if English, need to 25. Four times the conversion to the metric system. 7. According to the precision metal stamping parts graph labeling is the size of the material inside or outside, determine the foreign computation using the corresponding materials or materials. If the outside material for approval, then delete material inside, to outside inward offset a metric material thickness; If the material for approval, then delete material outside, to offset a metric material thickness on the paint. 8. With the size of the tolerance to take maximum limit of size and minimum limit of size of intermediate value, except the round hole. ( Note: when you pull the primitives, should pay attention to the size of the associated change) 。 9. If the precision metal stamping parts diagram is composed of 3 d converted into a 2 d image file or product extra lines on the drawing, will be one by one to delete. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
