1. What materials are usually used for stamping dies?
1. Common materials for stamping dies Stamping dies (also known as hardware molds) commonly used stamping materials are: Aluminum: aluminum, there are more aluminum materials for general appearance parts, such as notebooks or netbook keyboards, and some other accessories; Galvanized sheet: It is to coat the surface of the cold-rolled sheet with a zinc layer, commonly known as galvanized sheet.
2. At present, most of the materials used to manufacture stamping dies are mainly steel, and the types of materials commonly used for die working parts are: carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, high speed steel, matrix steel and cemented carbide, steel-bonded cemented carbide and so on.
3. The materials made of stamping dies include steel, steel-knotted cemented carbide, cemented carbide, zinc-based alloy, polymer materials, aluminum bronze, high and low melting point alloys, etc.
4. What is metal stamping? To put it simply, in fact, metal stamping is a kind of material cold processing process, a special process equipment that uses a mold to process metal materials into parts or shapes, called cold stamping die, and is also called cold stamping die in China.
5. The stamping die is a high-strength, high-precision mold, and the material selection of the mold affects the service life, performance and manufacturing difficulty of the mold. Common mold materials are as follows: Alloy tool steel Alloy tool steel is one of the more common mold materials, with high hardness, high strength, good wear resistance, thermal stability and other characteristics.
Second, the introduction of screw mold
1. Each piece of template is fixed with screws through screw holes, and the inner and outer molds are oiled. This kind of mold has the characteristics of high strength, high density and corrosion resistance, which can improve construction efficiency, reduce costs and improve project quality.
2. Screw mold is a mold for making screws, which is roughly divided into two categories: heading mold (main mold, wire mold, scissors, upper punch, lower punch, punching sleeve, sleeve, etc.); Thread rolling board (mechanical tooth thread rolling board, self-tapping thread rolling board, etc.).
3. The first step of screw forming is material preparation. The materials commonly used are metallic materials such as steel, stainless steel, copper, aluminum, etc. These materials need to be cut, forged, drawn, etc., to be processed into shapes and sizes suitable for screw forming. The second step in screw forming is cold heading. Cold heading is the process of processing a metal material through a mold into the shape of a screw.
4. C Self-drilling thread: directly used on the workpiece, screw drilling and tapping are formed at one time. Screw machining process A Turning: The method of removing the material to bring the material to its desired shape. Advantages: high processing accuracy, no mold limitations. Disadvantages: high cost, slow processing speed.
