The bronze dragon have lost the distinctive yellow color in those days


According to the above requirements of the die, the die part of the work is generally made of carbon tool steel or alloy tool steel. For high-speed stamping or require the life of the die, the part can be carbide production. 1.6-die forming characteristics die is a metal or non-metallic sheet at room temperature on the bronze mold, put pressure on the sheet through the press and the bronze mold, the sheet separation or deformation made the required parts of the Bronze mold. All kinds of Die forming is characterized by: blanking die.
Forming characteristics of the blanking die is: part of the material with another part of the material separation. Blanking die molding materials closed contours, and eventually get a flat parts. Punch blanking die molding is characterized by the materials in the parts separated with closed contours, so that part to get the hole. bending mode. Bending mold forming is characterized by: the sheet or billet blanking after pressure bent a certain angle and the shape of a bronze mold. 3) deep mode. Antique Chinese bronze sculpture : The lid of Lei.  Forming characteristics of the drawing die is pressed into the opening of the hollow parts: after blanking the plate billet. shaped mold. The forming die forming is characterized by: a variety of local deformation method to change the shape of the parts or billet. cold extrusion die. Cold extrusion die forming is characterized by: at room temperature in a bronze mold cavity metal billet pressure to produce plastic deformation, extruded into the desired shape, size and performance parts products.
Stamping bronze mold process and quality control of cold stamping bronze mold installation problems cold stamping bronze mold installed the installation of the bronze mold divided into two parts: First, the bronze mold loaded into the mold rack; to have been fitted into the punch within the entire pair of bronze molds to mold the shelves. assembly to check the fixed mold assembly screws, assembly to mold before assembly to the mounting surface of the mold deburring processing. Antique Chinese bronze sculpture : Elephant Zun. In particular, a bronze mold removed, there are a lot of screws, the specification of different lengths, the length of the fastening bolt into the bolt hole shall be 1.5 to 2 times greater than the bolt diameter. Such as M10mm bolts screwed into the threaded holes in the length should be 15 ~ 20mm. With a guide (ie column) mold, and put into bronze molds, all kinds of templates, the relative position between the next by the guide to ensure that, no adjustment. Simplify the design and manufacture of bronze mold bronze die life, reduce costs, shorten the manufacturing cycle of bronze mold has great significance. Die work of some of the parts must have the performance of the work of some of the parts die, also known as molded parts, which includes a punch and the die and punch. The bronze dragon have lost the distinctive yellow color in those days. Cold pressing and hot stamping, stamping, the stamping process is divided into separation processes (blanking) and the molding process (bending, deep drawing, forming) two categories. In the working process of the separation process, in addition to withstand the material separation of the desired impulse pressure, but also to withstand the intense friction between the materials section; in the shaping process, die in addition to withstand plastic deformation required for the impulse pressure , the surface is also subject to strong friction of the plastic flow of the material.
Therefore, the work site which requires die to have the impact resistance, wear resistance, high strength, high hardness performance. This vessel is only a lid of the bronze sculpture .  While heating the material state of the die working parts require heat resistance, so as to ensure the durability and service life of its dies.
