AI Technical Summary
The existing metal tube and bar inclined roller straighteners have an unreasonable four-legged slide block design, which results in inconsistent installation planes between adjacent slide blocks. This requires straightening roller bearing seats and anti-collision pillar mechanisms of different heights, posing a safety hazard.
It adopts an X-shaped sliding seat design, with trapezoidal and hollow cylindrical legs, and a dovetail groove structure to ensure that adjacent sliding seats are on the same plane, eliminating the need for an anti-collision pillar mechanism.
It achieves plane consistency between adjacent slide blocks, simplifies the structure, improves safety, and avoids installation complexity and potential accidents.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of metallurgical tube and bar straightening machine equipment, and mainly relates to a four-legged sliding seat mechanism for a metal tube and bar inclined roller straightening machine. Background Technology
[0002] like Figure 1 As shown, most conventional inclined roller straighteners for tubes and bars use a type of four-legged slide with a full circular hole. The four legs of the slide are fitted onto the uprights of the straightener and can slide up and down on the uprights, thereby adjusting the roller gap of the straightener to accommodate straightening tubes of different diameters. For multi-inclined roller straighteners, two adjacent four-legged slides need to share two uprights. This requires arranging the adjacent four-legged slides at different heights, resulting in a significant height difference between the mounting planes of the adjacent four-legged slides that mount the straightening rollers. To compensate for this height difference, straightening roller bearing seats of different heights must be configured on the same straightener. At the same time, an anti-collision mechanism must be designed between adjacent four-legged slides. If the anti-collision mechanism fails, it will cause a major accident. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this utility model is to propose a novel four-legged sliding block mechanism for a metal tube and bar inclined roller straightening machine.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A four-legged slide mechanism for a metal tube / bar inclined roller straightener is disclosed. The slide of the four-legged slide mechanism is X-shaped. Each of the four corners of the X-shaped slide is provided with a support leg, and the upper and lower end faces of the support legs protrude from the upper and lower end faces of the X-shaped slide. At least two of the four support legs located on the same side are trapezoidal support legs, that is, the cross-sectional shape of the support legs is trapezoidal. The column that cooperates with the support legs has a dovetail groove that slides with the trapezoidal support legs. The dovetail groove is provided on the side of the column and there are two symmetrically arranged left and right. The two dovetail grooves respectively cooperate with the trapezoidal support legs of two adjacent X-shaped slides, so that two adjacent X-shaped slides installed on the same column are located on the same plane.
[0006] All four of the aforementioned legs are trapezoidal legs.
[0007] Of the four legs, the two legs on the same side are trapezoidal legs, and the two legs on the other side are hollow cylindrical legs.
[0008] The dovetail grooves are arranged along the length of the column, allowing the trapezoidal legs to slide up and down along the corresponding dovetail grooves.
[0009] This utility model proposes a novel four-legged slide mechanism for a metal tube and bar inclined roller straightening machine. By setting two legs on the same side as trapezoidal legs, and having two adjacent X-shaped slides cooperate with their corresponding columns from both sides, the two adjacent X-shaped slides installed on the same column are located on the same plane. This avoids the phenomenon in the prior art where the legs of two adjacent X-shaped slides are fitted onto the same column, causing the two adjacent X-shaped slides to be not on the same plane. Furthermore, it eliminates the need for an anti-collision tower mechanism, resulting in a simple, convenient, and highly safe structure. Attached Figure Description

[0016] The present invention will be described in conjunction with the accompanying drawings and specific embodiments:
[0017] like Figure 6 As shown, and refer to Figure 4 , Figure 5 A four-legged slide mechanism for a metal tube / bar inclined roller straightening machine is disclosed. The slide 1 of the four-legged slide mechanism is X-shaped. Support legs 3 are provided at each of the four corners of the X-shaped slide, and the upper and lower end faces of the support legs 3 protrude beyond the upper and lower end faces of the X-shaped slide. Figure 2 Of the four support legs 3, two support legs on the same side are trapezoidal support legs, and two support legs 3 on the other side are hollow cylindrical support legs; the column 2 that cooperates with the support legs has dovetail grooves 4 that slide with the trapezoidal support legs; the dovetail grooves 4 are provided on the side of the column, and there are two symmetrically arranged left and right. The two dovetail grooves 4 respectively cooperate with the trapezoidal support legs of two adjacent X-shaped slides, so that the two adjacent X-shaped slides installed on the same column are located on the same plane; the column that cooperates with the hollow cylindrical support legs adopts a mature structure in the prior art, that is, a cylindrical column.
[0018] Alternatively, all four legs can be designed as trapezoidal legs, as shown in the reference. Figure 3 .
[0019] The dovetail grooves are arranged along the length of the column, allowing the trapezoidal legs to slide up and down along the corresponding dovetail grooves.
