Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold rolling equipment, in particular to an auxiliary rolling centering device. Background Art
[0002] Rolling is a metal processing process in which a metal blank is passed through the gap (of various shapes) between a pair of rotating rollers, where the compression of the rollers reduces the cross-section of the material and increases its length.
[0003] The "centering" of the rolled piece is one of the important conditions in the rolling process. When the centering effect is not good, the rolled plate will have quality defects such as "tower shape", "sickle bend" and "wedge shape", which will seriously affect the processing effect and product qualification rate.
[0004] As the automation level of production enterprises continues to improve, large rolling equipment has been equipped with precise rolling centering equipment. However, in some small rolling equipment or pilot-level production lines for technical research, the conditions for installing centering devices are not fully met. In this case, manual adjustment of the centering of the rolled piece will be more convenient, quick and accurate. Moreover, when the rolled piece is a smaller, thinner material, manual adjustment can better protect the material from damage and deformation than mechanical devices. Summary of the invention

[0015] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0016] See attached Figure 1 The utility model proposes an auxiliary rolling centering device, which includes an upper outer plate 1, an upper inner plate 2, a rotating handle 3, a support rod 6, a rotating screw 7, a lower outer plate 8 and a lower inner plate 9.
[0017] The upper outer panel 1 is arranged above the lower outer panel 8 at a certain height; the four corners of the upper outer panel 1 and the lower outer panel 8 are connected by four support rods 6, the four corners of the upper outer panel 1 are fixedly connected to the upper ends of the four support rods 6 by screws 4, and the four corners of the lower outer panel 8 are fixedly connected to the lower ends of the four support rods 6 by screws 4. The upper outer panel 1, the lower outer panel 8 and the support rods 6 play a role in fixing and supporting the entire device.
