Abstract
Description

[0001] This utility model relates to the field of steel bar processing technology, specifically to a wire drawing die for steel bar processing. Background Technology
[0002] Steel reinforcement is an indispensable building material and industrial raw material in many fields such as construction and machinery manufacturing. With the continuous development of modern industry and construction, the requirements for the quality, performance, and dimensional diversity of steel reinforcement are increasing.
[0003] In the process of steel bar processing, wire drawing is a crucial step. Existing steel bar wire drawing dies have complex structures and unreasonable designs. During the wire drawing process, a large amount of friction is generated between the steel bar and the die, requiring lubrication. The current lubrication method usually involves setting up a lubrication cavity before wire drawing, with the steel bar passing through the lubrication cavity filled with lubricating oil, causing the lubricating oil to adhere to its surface. However, when the size of the steel bar is changed, the sealing performance of the lubrication cavity will decrease, making it unsuitable for steel bars of different sizes. Furthermore, the exposed lubricating oil evaporates quickly, resulting in a large amount of wasted lubricating oil. Utility Model Content
