Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel wire heating technology, specifically a steel wire preheating device. Background Technology
[0002] Heat treatment of steel wire is a very important process in steel wire processing. After heat treatment, the steel wire regains the conditions that are conducive to cold drawing. Heat treatment can restore the internal structure of the steel wire, so that it can be drawn again. This makes it less prone to breakage and can achieve the required strength.
[0003] A steel wire preheating device disclosed in Chinese Patent No. CN222551708U includes: a positioning plate, with clamping components provided at the middle positions of the left and right sides of the upper surface of the positioning plate, and a moving component provided inside the front end of the positioning plate, with a positioning piece connected to the upper end of the moving component. The serrated structure can increase the friction between the clamping strip and the steel wire, making the clamping more stable.
[0004] Although the device achieves preheating of the steel wire, it only heats the steel wire with the flame from the blowtorch. The heating effect is poor on the side of the steel wire away from the blowtorch, and the heating is not uniform enough. Therefore, we propose a steel wire preheating device to solve the above problems. Utility Model Content
