Description

Cold drawing equipment with uniform lubrication effect

Technical Field

The utility model relates to the field of cold drawing equipment, in particular to cold drawing equipment with uniform lubrication effect.

Background

Cold drawing is a process of working by utilizing the ductility of a metal material, which is mainly to pass a rod-like or long-strip-like metal through a circular hole having a smaller diameter or other hole of a specific shape to obtain a metal material of a specific diameter or a specific shape. However, during cold drawing, friction between the raw material and the die hole is trivial and severe, so that even if the hardness of the die hole is higher, the die hole is worn out after practical use for a certain time to cause diameter change, and frequent replacement of the die is required. In order to solve the problem, lubricating oil is often used for pre-lubricating the raw materials, but liquid lubricating oil is adopted, so that the upper lubricating oil is less reserved when the lubricating oil moves along with the metal raw materials after lubrication, the upper part of a die hole is more severely worn, and the shape of a processed product is not satisfactory.

Therefore, there is a need for an improvement in such a structure to overcome the above-mentioned drawbacks.
