In metal press processing, a tool that forces a metal through a mold under an external force, the cross-sectional area of the metal is compressed, and the required cross-sectional shape and size is obtained.
Drawing die is widely used, such as high-precision wire used in electronic devices, radar, television, instrument and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are drawn by diamond wire drawing die. The diamond wire drawing die has a strong wear resistance and a very high service life due to the use of natural diamond as a raw material. The production process of the wire drawing mold sleeve includes several process steps such as compression molding, drafting and turning.
The wire drawing die is a wire that passes through a mold to make it from the coarse to the fine, and gradually reaches the size required by people. This special mold is a drawing die. The core of the wire drawing die is generally made of natural diamonds, synthetic diamonds (artificial diamonds). There are GE, PCD, synthetic materials, etc.). Copper wire drawing die is a soft wire drawing die. There are hard wire drawing die, such as pulling tungsten wire. The angle of the copper wire drawing die compression zone is generally 16-18 degrees. The length of the diameter is 30-40% and the angle of the compression zone of the tungsten wire drawing die is relatively small, generally 12-14 degrees, and the length of the wire is 60-70%.
The wire drawing die includes a diamond wire drawing die, and also includes a carbide wire drawing die; a plastic wire drawing die and the like. There are still many uses
