Sheet metal die waste knife parts ordering improvement report 1 improvement background: at present, there are many unreasonable ways to manufacture and design waste knife parts ordering. :(1)
Some of the materials are inconvenient to process, and the beveled surface cannot be heat treated; (2)
After heat treatment, the inclined plane and width, and the blanking step on the back cannot be ground and finished to a few times at one time, and the inclined plane can only be finished by wire cutting alone after heat treatment. (3)
The back step can only be ground separately after wire cutting, which leads to an increase in the manufacturing and processing cost of the stamping die, which cannot be effectively controlled and loses the significance of combining and ordering materials.
The project plans to establish a reasonable standard for the manufacture of scrap knives by the design department II, and to train all internal personnel to establish a unified standard :(1)
The width and inclined plane are arranged in a straight line, and the milling machine can be used to open the thickness once before heat treatment ,(2)
The bevel and back blanking steps can be ground once after heat treatment without wire cutting.
Each part of the second section of sheet metal design establishes the latest, most complete and best standards. New and old colleagues adopt uniform standards when designing the same part, and there will be no unreasonable design methods, therefore, unnecessary processing costs are caused and the processing cost of stamping die manufacturing is reduced.
