TECHNICAL FIELD

[0001] The utility model relates to rack production technical field, concretely relates to a guide of steel bar production. BACKGROUND

[0002] Rack steel is the raw material of rack production, and a long strip rack steel with a thickness of 43mm and a width of 63mm is known. The long strip rack steel needs to be guided and positioned by a guide during production.

[0003] For example, Chinese patent application CN218340667U discloses a steel rolling guide assembly with easy-to-replace guide wheels, which includes a guide box and a guide mechanism. The guide mechanism includes an upper fixed plate, a lower fixed plate, and guide wheels. The lower fixed plate is arranged directly below the upper fixed plate. The guide wheels are arranged between the upper fixed plate and the lower fixed plate. A wheel shaft is arranged through the middle of the guide wheels. An upper fixed block is fixedly connected to the top end of the wheel shaft. A lower fixed block is fixedly connected to the bottom end of the wheel shaft.

[0004] However, when the steel rolling guide assembly with easy-to-replace guide wheels is used, the middle of the guide wheels is worn and depressed after long-term processing. Due to uneven thickness, different line speeds, and torsion during rack steel rolling, the worn and depressed areas are not uniform, which ultimately causes the finished product cross-section to appear as a parallelogram, resulting in defective products.
