AI Technical Summary
When rolling small-sized products, the newly added pinch rolls cannot stably keep the rolled piece at the center of the pinch roll pass, causing the rolled piece to deviate from the center and resulting in pinch damage. This is especially true at the exit of the finishing mill, where steel tends to pile up and triangular crushing damage can occur.
Design a pinch roll inlet guide device, including a rectangular through-hole cavity with variable diameter and a detachable inlet guide tube. By changing the shape of the guide tube cavity and the structure of the guide box, the left and right swing of the rolled piece is restricted, ensuring that the rolled piece passes stably through the center of the pinch roll pass.
It effectively limits the left and right swaying of the rolled piece in the clamping roll pass, avoids indentation on the finished product, and improves the stability of the rolling process and product quality.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0029] This utility model provides an inlet guide device for a pinch roller, comprising an inlet guide box 100 and an inlet guide tube 200. The inlet guide tube 200 is detachably installed inside the inlet guide box 100, with both ends of the inlet guide tube 200 located outside the sides of the inlet guide box 100. The inlet guide tube 200 has an inner cavity 210, which is a rectangular through hole with a variable diameter.
[0030] By changing the shape of the inner cavity 210 of the inlet guide tube 200 and redesigning the inlet guide box 100, the range of left and right swing of the rolled piece is limited, thus preventing the rolled piece from swinging left and right in the clamping roll hole and causing indentations in the finished product.
[0031] In one embodiment, see Figure 1The inner cavity 210 includes an inlet section 211, a square hole section 212, a transition section 213, and an outlet section 214 connected in sequence. The opening area of the larger end of the inlet section 211 is larger than the opening area of the smaller end of the inlet section 211. The smaller end of the inlet section 211 is connected to the square hole section 212, and the opening area of the smaller end of the inlet section 211 is the same as the opening area of the square hole section 212. The square hole section 212 is a square through hole. The tail end of the square hole section 212 is connected to the transition section 213, and the opening area of the tail end of the square hole section 212 is the same as the opening area of the inlet end of the transition section 213. The opening area of the larger end of the transition section 213 is larger than the opening area of the smaller end of the transition section 213. The smaller end of the transition section 213 is connected to the outlet section 214, and the opening area of the smaller end of the transition section 213 is the same as the opening area of the inlet end of the outlet section 214.
[0032] With this design, the inner cavity 210 of the guide tube is changed from the original round hole to a variable diameter rectangle, and the inner hole is changed from a single round hole to a square hole. Then, it goes through a sloped transition section to the outlet end. In order to limit the left and right swing amplitude of the rolled piece, it ensures that the rolled piece is in the center of the clamping roll hole.
[0033] For example, the square hole segment 212 has a square hole diameter of 12x12mm.
[0034] For example, the outlet section 214 has a rectangular aperture of 12 x 7 mm or 12 x 9 mm.
[0035] In one embodiment, see Figures 2-3 The imported guide box 100 includes a loading box 110 and a top cover 120. The top cover 120 is detachably mounted on the loading box 110. The imported guide box 100 also includes a fastener 130. The top cover 120 is fixed to the loading box 110 by the fastener 130, which is a bolt assembly.
[0036] The top cover 120 has a through hole with a thread inside, and the loading box 110 has a corresponding threaded hole. The top cover 120 is fixed to the loading box 110 by a bolt assembly, and the inlet conduit 200 can be adjusted and replaced.
[0037] The loading box 110 is provided with a through hole for loading the inlet conduit 200.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
