Common damage problems of cold heading machines and what should be paid attention to during operation

Why do cold heading machines have different degrees of damage during use? The most common cold heading machines are quality problems that lead to cold heading cracking. Why does it cause cracking? The reasons for cracking are mainly divided into internal quality problems of the strip, surface quality problems of the strip and improper user deep processing technology. The internal quality problems of the strip are mainly caused by inclusions. Generally, slag inclusions are caused by rolling slag during continuous casting. The type and grade of non-metallic inclusions are also another reason that affects the internal quality of the strip. There are very few cold heading cracks caused by non-metallic inclusions.

Here, let’s share the precautions for cold heading machine operation. First, apply a certain pressure to the metal blank at room temperature to cause plastic deformation in the mold cavity and form according to the prescribed shape and size. 2. The cold heading machine must choose high-quality "plastic transformation" metal materials. 3. The cold heading machine has cold hardening during the upsetting process, and the deformation should not be too large. Cracking must be reduced. 4. The cold heading machine technology is applicable to large batches and various specifications, so that costs can be reduced and thus greater benefits can be reduced. Even the better cold heading machine must be operated in standard no matter at any time, so that it can not only extend the life of the machine, but also ensure the safety of our operators. Therefore, having a high-quality cold heading machine can not only greatly improve our working efficiency, but also reduce the degree of fatigue when working.
