Description

Technical Field

[0001] The present application relates to the technical field of rolling mills, for example, to a double rolling mill drive device. Background Art

[0002] The related art (Announcement No.: CN220574327U) discloses a roller die rolling mill for spring steel wire production, including a main frame, a movable roller seat is movably installed near the top of the main frame, and an upper roller is rotatably installed inside the movable roller seat, and a lower roller is rotatably installed at the bottom of the upper roller. A first auxiliary frame is fixedly installed on one side of the main frame, and a feeding mechanism is movably installed inside the first auxiliary frame near the upper roller and the lower roller, and the feeding mechanism includes an upper feeding roller and a lower feeding roller of the feeding mechanism.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The roller die rolling machine for spring steel wire production continuously feeds the material between the upper roller and the lower roller through the upper feed roller and the lower feed roller for rolling. During the rolling process, the upper roller and the lower roller rotate as the material is continuously fed. Since the upper roller and the lower roller cannot rotate by themselves, when the material is conveyed too fast, it is easy to accumulate between the upper roller and the lower roller, thereby affecting the quality of the material roll forming.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
