Tungsten Carbide Wire Drawing Die’s Annealing

Tungsten carbide wire drawing dies and annealing process consists of the two main steps. Firstly, steel annealing, in which steel is heated to and maintained at the required temperature, for a certain period of time, and slowly cooled down (generally with the furnace cooling). Secondly, die drawing (in the annealing process) , which is usually through electrical contact; electrodes transfer electric current on a copper wire; in order to extract copper wire, preheating and heating takes place. Preheating is usually up to 250 C degrees, because higher temperature will enable oxidation. Heating stage is around 500-550C degrees, which leads to recrystallization. Heating stage has steam protection; it prevents copper wire from oxidation, and after water-cooling stage, the annealing (softening) process is finished.

What is Tungsten Carbide Stamping Die?

Tungsten carbide stamping die occurs in a room temperature. It uses pressure from the punching machine, via a variety of different size of materials for die processing, forms the desired shape and size of the parts. The material used for stamping is metal material. Metal materials include:steel, steel, non-ferrous metal (copper, aluminum and its alloys, etc.) Panels, strip material and various shapes such as: steel angle, steel channel etc. Non-metallic materials are following: paper sheet, cloth sheet, mica, cardboard and similar. Stamping is one of the advanced processing methods, which is mainly the processing of sheet metal, also known as sheet metal stamping. In cold stamping there is no need for heating or for cutting. It is energy-efficient processing method, because cutting large metal into pieces consumes a lot of energy, and in this method we save that. The raw materials used for stamping products, like plate, strip that come from mass production of metallurgical plant, during stamping their quality of surface is not destructed. No other processing method can compare with this one.

What is Tungsten Carbide Punching Die?

Tungsten carbide punching die is used for sheet metal stamping and separation of the mold. Cavity is used for forming the mold; blade is used for separating the mold. The most common stamping mold has only one workstation, completed production process. This type of mold has universal application, simple structure, it’s easy to manufacture, but it has low productivity. In order to improve productivity, there can be used many channels, such as: blanking, drawing, punching, trimming and other channels arranged in a mold, enabling blanks in one station complete multi-channel stamping process. This mold is called a compound mold. Another way is to have multiple processes, like blanking, bending, deep drawing, punching and trimming, etc., arranged on one mold in different work stations.

What is Tungsten Carbide Forging Die?

Tungsten carbide forging die is used for hot metal forging in forming mold. When forging, blanks have to go through many deformations until they finally can be forged. This requires that there are few cavities engraved in a module, and metal is put respectively in each cavity, followed by the plastic flow into cavity and finally, filled cavities form forgings. In forging forming process, it is very difficult for blanks to equal with the end forging cavity volume, so in order to avoid waste; we can use larger selection of blanks. In the final forging die, above, below the mode surface of the cavity, there will be burrs tank, set up for four weeks, so that it can store the excess metal from the cut our molding burrs. In order to facilitate the flow of metal and plastic filling, reduce mold wear and cracking and improve die durability, the mold cavity sharp corners and deep grooves should be minimized.

Straight Tungsten Carbide Drawing Dies Introduction

Straight tungsten carbide drawing dies are made​in accordance with "linear" theory, this theory was developed by the American T Maxwall and EG Kennth proposed. With the improvement of the life drawing speed tungsten carbide drawing die has become the most prominent problem, linear tungsten carbide drawing die has four major characteristics. First. Linear Carbide drawing dies entrance area and straight tungsten carbide drawing die lubrication area combined with a tendency to make lubricating angle decreases while the lubricant before entering the work area will be subject to certain pressures and thus play better lubrication. Second. Linear Carbide drawing dies entrance area and straight tungsten carbide drawing dies used to create a better work area extended lubrication pressure.

Arc-Type Tungsten Carbide Drawing Dies Introduction

Tungsten carbide drawing dies mold core work area is rendered "arc-type" and thus make metal tungsten carbide drawing dies mold core deformation in the region even more tortuous flow leads to unnecessary additional shear deformation and deformation work increased so that the drawing stress in general than the "straight" Carbide drawing dies mold core work area increases by 10 to 30%, but "straight" Carbide drawing dies mold core work area each contour line the slope is the same point so that when we determined the optimum cone half-angle α workspace when you can pull the metal with minimal stress and drawing "arc-type" Carbide drawing dies due to the curvature of each point of its contour line different and therefore can not make the whole Carbide drawing dies mold core work area there is an optimal workspace cone half-angle α.
