Forging die is nothing more than the sum of guiding forging and pressing dies, which are referred to as "forging die" and "extrusion die" for short. The English name "ForJing Die" is the output die used for cold forging and forming.
Since the steam engine was invented in the West in 1840, the western industry has been put into use. A large number of ships and military products processed and produced have been used for production. Due to the limitation of the equipment for processing products, machinery manufacturing enterprises have manufactured the forming equipment for heating treatment. Because we have always been used to call it forging equipment, so far, the forging equipment that people call it has been applied to today's metal processing and production, The die for fixed forming is also called forging die.
Since the 1960s, especially the metal materials of some clocks, mobile phones and handicrafts need to reach a specific size and effect. The materials are heated by the previous forging press to 30-350 degrees through a high-temperature furnace, and then put into the machine for forging to form products, which are similar to the principles of die casting and steelmaking.
In 2000, with the rise of market products and updated technologies, products with communications, precision hardware, and precision electronics as the mainstream were processed with titanium, copper, and aluminum metals that are more durable and have superior conductivity as raw materials to achieve new properties of higher hardness, deformation resistance, plasticity, and impact resistance. Through the combination of cold forging dies with improved cold forging equipment on the market, forging products with more technical content were produced, Due to their different principles, they are called similarly, also known as "cold forging dies". At this time, the cold forging dies are different from the forging dies before the 1980s, which should be distinguished.
Through the above explanation, I think we also know the development process and manufacturing process of cold forging die manufacturers. Now, please allow us to share its fine process attributes with Chengda Forging:
1、 Process overview:
The design of forging die shall follow the three principles of good service performance, excellent processing performance and some economic performance. At the same time, it is necessary to be familiar with the process characteristics of metal forging forming, master the basic structure and working performance of various forging equipment, and design a die with good formability, reasonable service life, and easy installation, debugging and maintenance from the actual conditions.
2、 Key points of design:
Based on materials and forming process, the following points should be taken into consideration when we focus on cold forging:
1. Appearance of forgings:
Appearance is the direct effect of the product, square is round, and the actual output is the final conclusion.
2. Shape of forgings:
The forging with complex shape needs to adopt the method of dispersed deformation of multiple die chambers to reduce die load, reduce press tonnage and avoid forging defects.
3. Forging equipment:
Mainly consider forging press, cold extrusion press and forging punch
4. Mold:
Forging die is an important equipment to realize die forging process and a branch of die category with a long history. Due to the complexity of forging process, the corresponding forging die has the following technical characteristics:
(1) Metal forging forming belongs to bulk forming, which is difficult to achieve one-step forming and requires multiple deformation. The forming steps of complex forgings can reach as many as 12 steps. Therefore, a set of forging dies is often composed of one or more pairs of dies.
(2) Workpiece shaping: the load borne by the die used for steel forging reaches 100-5000MPa
(3) Due to the flow of metal blank during deformation under high temperature and high pressure, except for the normal parting surface, the forging die cavity needs to maintain the integrity of the working surface of the cavity, and cannot adopt the inlay structure.
The technical characteristics of the forging die determine the design of the forging die, which strongly depends on the design of the forming process. It is necessary to select die materials well and carry out reasonable heat treatment. Advanced processing technology is used to ensure the precision and surface quality of the die cavity.
The products are constantly updated, and the technology is also constantly improving. In the future, Rentong firmly believes that faster, simpler, and more intelligent molding technology will become a new scene of manufacturing. Easy operation and more productivity are more consistent with the social identity of improving productivity and low labor force!
In the past 10 years, we have successfully assisted more than 380 metal enterprises in developing LED lamp radiators, lamp cups, handicraft trophies, coins, clock surfaces, dials, automobile shaft sleeves, middle rotors of motors, electronic motors, automobile wheel drums, bicycle parts, medical high fiber crystals, photoconductive products, and aerospace ship supporting products, from the research and development, trial production and mass production of the first batch of forging dies in China to national enterprise guidance, It involves 36 major industries. In 2019, Chengda Forging is willing to go forward with you and create new heights!
