Metal stamping parts processing plant, processing all kinds of metal stamping parts, stainless steel stamping parts. Machinery accessories, etc. Design matching molds before processing metal stamping parts. Mold parts drawing requires professional personnel to design and draw. Let’s take a look at some of the requirements for drawing parts of metal stamping parts. 1. The view of the part drawing of the metal stamping die should be correct and sufficient: the selected view should fully and accurately show the internal and external structure and size of the part, and the number of views should be the least. 2. The graphics should be drawn intact: the purpose of drawing the part drawing of the stamping die is to reflect the structure of the part and provide graphical instructions for processing the part. All non-standard parts or parts that still need further processing although they are standard parts need to be drawn part drawings. Although some parts are standard parts, they still need to be processed with leaking holes, screw through holes and pin holes, so drawing parts of stamping mold parts. Parts such as guide posts, guide sleeves and screw pins are standard parts and do not require further processing, so part drawings are not required. 3. The view of the part drawing of the metal stamping die should be arranged correctly: in order to ensure that the drawing of the part drawing is correct, it is recommended to draw the part drawing according to the assembly position, and the shaft part shall draw the part drawing according to the processing position (generally the axis line is arranged horizontally). The front view of the part on the assembly drawing reflects the structure in the thickness direction, and the top view is the structure in the original plane. 4. The dimensions should be correct: all matching dimensions and dimensions with higher precision requirements should be marked with tolerances. The dimensions of metal stamping die parts that need to be processed during the assembly process should be marked on the assembly drawing. If it must be marked on the part drawing, it should be marked next to the relevant dimensions. When a certain amount of assembly margin is required for assembly, the compensation amount of the assembly chain and the required matching dimensions, tolerances and surface roughness after assembly can be marked on the part drawing. 5. To meet the corresponding technical requirements: all the conditions and requirements that are not easy to express in symbols or drawings, but must be guaranteed during manufacturing, should be indicated in the technical conditions, and their content varies with different metal stamping parts Parts, different requirements and different processing methods are different.
