    Introduction to multi station cold heading machine

    Source:http://www.00d0.cn     Author:多工位冷鐓機     Time:2014/8/22     Click:
    The multi station automatic cold heading machine uses cold heading method to automatically punch 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 The cold heading station is arranged horizontally and has the characteristics of accurate positioning, stable operation, and convenient maintenance, making it 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.
    For cold heading machines, they are mainly specialized equipment for producing batches of nuts, bolts, and other fasteners based on piers. The country that first manufactured cold heading machines was Germany, and at that time, cold heading machines were mainly used for producing bullet shells. Therefore, the process characteristics of cold heading machines are as follows:
    1. Cold heading machines are mainly manufactured based on the theory of metal plasticity, and when selecting metal materials, their quality is also very high, with very strict standards, especially for the chemical composition and mechanical properties of rivet steel
    2. Cold heading machines have good surface quality and high dimensional accuracy during production. They also have good cold work hardening during the forging process, which can maintain good deformation and prevent significant deformation, thereby reducing the occurrence of product cracking and other phenomena.
