Drawing of Metal Stamping Die Drawing

Drawing of metal stamping die drawing

After fully analyzing the original data of metal stamping parts, the die designer needs to perform relevant process calculations. Then on this basis, the overall structure and size of the die can be designed, and then the die assembly drawing and parts drawing can be drawn. The following is an introduction to the drawing of the die drawing.

The first step in die drawing is to draw a sketch of the die structure; the second step is to draw the die assembly drawing based on the die sketch; finally, the die parts drawing is drawn according to the die assembly drawing.

When drawing the die sketch, the designed die structure should be fully considered to ensure the quality of the stamping parts, meet the production batch requirements, be convenient and safe to operate, easy to manufacture and maintain, and have a long service life. Under this premise, the selection of positive and negative structures, elastic rigid unloading or discharging, positioning methods and guiding methods should be focused on, so as to make them as reasonable as possible.

When drawing the die assembly drawing, in the assembly drawing, the main view and top view (side view and partial section view should be drawn if necessary) should clearly reflect the assembly relationship between the various parts and the fixed connection method, and mark the plane size and closed height size of the die. The layout diagram or process diagram should also be drawn in the upper right corner of the drawing, and the title bar and detailed list should be drawn in the lower right corner of the drawing. If necessary, it is also necessary to write technical requirements and instructions on the assembly, maintenance, operation and other aspects of the mold.

When drawing the mold part drawing, the part drawing should clearly express its structural shape, and should indicate all dimensions, tolerance dimensions, form and position tolerances, surface roughness, materials used, heat treatment requirements and other relevant technical requirements.

After the mold drawing design is completed, it must be checked. This is an indispensable step in the design work, because it is difficult for any mold designer to ensure that the design drawing is error-free.
