Reasonable design of precision stamping die

The convex and concave molds of precision stamping die parts are the working parts that directly shape the blank, so it is the key part of the mold. Convex and concave molds are not only precise but also complex. They should meet the following requirements: (1) It should have sufficient strength and cannot be broken or damaged during the stamping process; (2) There should be appropriate requirements for its material and heat treatment to prevent the hardness from being too high and brittle crack. Precision stamping die positioning parts are the parts that determine the installation position of the blank. There are positioning pins, stop pins, guide pins, guide plates, fixed distance side cutters, side presses, etc. When designing positioning parts, you should consider the convenience of operation, there should be no positioning, and the location should be easy to observe. It is best to use forward positioning, outer profile positioning and guiding pin positioning. Guide posts and guide sleeves of precision stamping die guide parts are the most widely used guide parts. Its function is to ensure that the convex and concave dies have a precise fit clearance during the stamping work. Therefore, the gap between the guide post and the guide sleeve should be smaller than the blanking gap. The guide post is set in the lower mold base, and the upper end surface of the guide post is at least 5 to 10 mm above the top surface of the upper template at the bottom dead center of the stroke. The guide post should be arranged far away from the module and the pressing plate, so that the operator's arm does not need to cross the guide post to feed and retrieve the material. Precision stamping die support and clamping parts include upper and lower templates, die handles, convex and concave die fixing plates, backing plates, stoppers, etc. The upper and lower templates are the basic parts of the die, and various other parts are respectively installed and fixed on it. The plane size of the template, especially the front and rear direction, should be compatible with the workpiece, too large or too small is not conducive to operation. Fastening parts of precision stamping die include screws, nuts, springs, pins, washers, etc., generally standard parts are used. There are a lot of standard parts of stamping dies, and the design and selection should ensure the needs of tightening and elastic ejection, avoiding the fasteners from being exposed on the surface operation position, and preventing hand injury and hindering operation.
