How To Choose The Material of The Mold Punch, What Material Is Used for The Mold Punch Needle?

First, what are the commonly used materials for metal mold punch and die:

1, such as: stretching punch, bending punch, slide insert knife, salad punch, punch, germinating punch, riveting punch and so on. The hardness of the punch material needs to be higher, and the punch materials often used are: Cr12Mo1vCr12Mov, Skd-5Skd-1W6Mo5Cr4V2(tungsten steel).

2, such as: stretching punch, bending punch, slide insert knife, salad punch, punch, bud punch, riveting punch and so on. The hardness of the punch material is higher, and the commonly used punch materials are: Cr12Mo1vCr12Mov, Skd-5Skd-1W6Mo5Cr4V2(tungsten steel).

3, high-quality material recommendation SKD1SKD11 is a high-quality die steel material, with excellent wear resistance, toughness and tensile strength. Its special structure and heat treatment process make it excellent in the production of convex and concave die. The hardness of SKD11 can reach 60-62HRC, so the durability and life of the mold can be guaranteed.

4, such as: stretching punch, bending punch, slide insert knife, salad punch, punch, bud punch, riveting punch and so on. The hardness of the punch material is higher, and the commonly used punch materials are: Cr12Mo1vCr12Mov, Skd-5Skd-1W6Mo5Cr4V2(tungsten steel).

5, stamping mold commonly used materials - metal mold commonly used stamping materials are: aluminum and aluminum, general appearance parts with more aluminum, such as notebook or netbook keyboard, some other accessories; Galvanized sheet is a zinc layer plated on the surface of cold rolled sheet, commonly known as galvanized sheet.

6. What are the commonly used materials for stamping die? The materials for manufacturing stamping die are steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low melting point alloy, aluminum bronze, polymer materials and so on.

Second, what materials are generally used for the punch head:

1, the selection of the punch material should be based on the stamping speed of the high-speed stamping die, the material characteristics of the stamped material (such as copper, aluminum, galvanized sheet, tinplate, stainless steel, etc.), the thickness of the stamped material, the hardness of the stamped material and other factors.

2, the selection of the punch material should be considered according to the stamping speed of the high-speed stamping die, the material characteristics of the stamped material (such as copper, aluminum, galvanized sheet, tinplate, stainless steel, etc.), the thickness of the stamped material, the hardness of the stamped material and other factors.

3, the punch head "punch" generally use what material? The selection of the material should be considered according to the stamping speed of the high-speed stamping die, the material characteristics of the stamped material (such as copper, aluminum, galvanized sheet, tinplate, stainless steel, etc.), the thickness of the stamped material, the hardness of the stamped material and other factors.

4, (theory) grinding amount = punch cutting edge length - return plate thickness - material thickness - die depth For C, D, E station of the old structure of the punch, if the height of the gasket is too large, the keyway of the punch and the positioning key on the punch seat can not be matched, will cause the shaped mold can not be used normally. Therefore, the larger grinding amount of the punch can only be 3mm.

5, the preliminary positioning of the mold with tight, and then the punch point close to the mold, and then side observation, screw the punch nut to ensure that the mold around the gap is equal. Tighten the mold, point and observe the mold alignment, test punch the parts, check whether the parts have a flash phenomenon, if there is a local adjustment. The mold must be strong so as not to damage the mold and press.

6, sink drilling: In order to obtain a smooth surface effect in aircraft structure repair, when installing countersunk rivets or screws, it is necessary to make a similar concave in the material from the rivet head. A countersunk drill is a tool used to cut a tapered socket at the edge of a hole. The drilling Angle of the aerial countersink is generally 100 degrees.
