The difference between cold heading machine and multi station automatic cold heading machine

Source:http://www.lgongchem.com     Author:多工位冷鐓機     Time:2014/8/19     Click:
The multi station automatic cold heading machine uses cold heading method to automatically forge various hexagonal nuts from optical disc elements or bar materials, and then thread them to produce standard hexagonal nuts. The bar material is fed through roller drive, and is sequentially fed, cut, pressed, angled, punched, and several processes are completed in one machine Cold heading horizontal arrangement, with accurate positioning, stable operation, and convenient maintenance, is suitable for manufacturers to mass produce nuts. Multi station automatic cold heading machine is a specialized equipment for producing hexagonal nuts and some non-standard components. Using single-sided S-board cutting is more stable and powerful, and the time can be adjusted.
Cold heading machine is a specialized equipment mainly used for mass production of nuts, bolts and other fasteners. The world's earliest cold heading machine originated from Germany. The main purpose of developing cold heading machines at that time was to produce a large number of bullet shells during World War II. The process characteristics of cold heading machine are as follows
 
1. According to the theory of metal plasticity, a certain pressure is applied to the metal billet at room temperature to cause plastic deformation in the mold cavity, and it is formed according to the specified shape and size.
2. It is necessary to choose high-quality metal materials with good plasticity, such as rivet steel, whose chemical composition and mechanical properties have strict standards.
3. There are multiple models and series of cold heading bolt and nut forming machinery available. The equipment has reliable performance, high efficiency, and stable product quality.
4. The product has a large forging force during molding, and the configuration power is high. The equipment requires a large initial investment. Therefore, producing specifications below M24 is the most economical.
5. Has good surface quality and high dimensional accuracy. Due to the presence of cold work hardening during the forging process, the amount of deformation should not be too large. Reduce cracking.
6. The cold heading process is suitable for products with large quantities and various specifications, in order to reduce costs.
