1. What is a drawing die?
1. To put it bluntly, a drawing mold is a mold that stretches and extends a flat plate to further change the shape and size.
2. The drawing process is the first process of automobile stamping parts product forming, through the drawing die on the press to stamping the flat material into a workpiece with the basic shape of the product, on the basis of a reasonable stamping process, the drawing die structure design and debugging research is the top priority of the automobile stamping parts to achieve the forming requirements.
3. Single-action drawing die: The single-action drawing die for automobile mold design is to use the air cushion mechanism of the machine tool to press the material, and rely on the punch and die for forming. It is characterized by simple structure and convenient mold installation. Double-action drawing die: Automobile mold design double-action drawing die is the use of the machine tool outer slide mechanism to press the material, relying on punch and die for forming.
4. Drawing die is a kind of processing tool used for metal, plastic and glass and other materials. It is a rod or wire that is processed and processed to turn the raw material into an elongated shape or a rod or wire with a smaller diameter through deformation methods such as tension and compression.
5. Drawing die: "drawing die" is generally written in books about metal cold stamping, which is actually what some people call "drawing die" or "drawing die".
In the process of drawing the blank of the workpiece with a non-extensible surface, it is partially stretched or drawn, so the drawing die is also called a drawing die or drawing die by some people.
6. Definition: The outside of the edge pressing ring and the column cast from the lower die base (usually at the four corners of the mold) are called external guidance. Scope of application: The shape of the applicable workpiece is too irregular, resulting in the situation that the edge pressing ring is not convenient for the use of internal guidance (such as slender beam parts), or the drawing stroke is large and the edge pressing ring is not convenient for the use of internal guidance.
Second, what are the mold materials?
1. There are more than 100 kinds of materials that can be used for mold processing, such as metals, plastics, inorganic non-metals and paraffin, etc., but according to the actual needs, the use and demand of each material are different, today, we will talk about 24 kinds of metal materials that are more commonly used in mold processing.
2. Types of mold materials: forging forming molds; stamping dies; plastic molding molds; metal molds for casting; die-casting molds; powder metallurgy mold forming mold; glassware molds; rubber molding molds; ceramic molds; Economic molds (simple molds).
3. Alloy tool steel is one of the more common mold materials, which has the characteristics of high hardness, high strength, good wear resistance and thermal stability. It is suitable for small and medium-sized batch production and demanding products. Tungsten carbide steel Tungsten carbide steel is an advanced mold material with the characteristics of high hardness, high strength, strong wear resistance and high corrosion resistance.
4. Types of mold materials There are many types of mold materials, and the commonly used ones are mainly the following categories: Metal materials: The hardness of metal materials is high, which is very suitable for making molds with high precision requirements, and the commonly used metal materials are: cemented carbide, tool steel, special steel, cast steel, etc.
5. Plastic materials have excellent machinability, wear resistance and strength, and are suitable for manufacturing large and complex molds. Commonly used plastic materials are polyethylene, polystyrene, polycarbonate, etc. Ceramic materials Ceramic materials have high hardness, good wear resistance, can withstand high temperature and high pressure, and are suitable for manufacturing molds used under high temperature and high pressure.
