Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling production equipment, in particular to a side guide component capable of automatic centering. Background Art

[0002] The side guide structure plays a vital role in the coiling process of thin slabs. The side guide structure, also known as the guide structure, is usually in the shape of a plate or strip. It is an important component in the hot rolling production line. Its main function is to ensure the stability and directionality of the hot rolled strip during its travel, especially in the stage before coiling. The side guide structure avoids coil defects by accurately guiding the head of the strip into the coiler and aligning it with the center line of rolling. The opening width should be suitable for the rolling width of the strip. The side guide device helps to control the edge shape of the thin slab. By adjusting the tension and shape of the edge, curling can be prevented and corrected.

[0003] As the side guide is one of the main consumable parts, it is replaced relatively frequently. The replacement of the side guide needs to be completed by the crane. To ensure the smooth loading and unloading, the gap reserved in the matching part is relatively large. In order to eliminate the gap after assembly, a centering sleeve is installed on the top. The action point of the centering sleeve is at the top, while the action point of the side guide is at the bottom. Therefore, the pin hole gap at the bottom is not eliminated, resulting in distortion of the positioning control effect and poor accuracy. Utility Model Content

[0011] Furthermore, the side wall of the groove is provided with an avoidance groove corresponding to the abutment portion.

[0012] Furthermore, the side wall of the groove is used to abut against a side of the centering portion that is away from the centering fitting surface, so as to limit one of the travel end points of the rotation range of the centering piece.

[0013] Furthermore, the top wall of the avoidance groove is used to abut against a side of the abutment portion facing away from the abutment surface, so as to limit another end point of the rotation range of the centering member.

[0014] Furthermore, a plurality of lifting ears are provided on the upper end of the side guide body.

[0015] Furthermore, each of the side guide bodies is provided with at least two positioning cylinders, wherein at least one positioning cylinder has four centering pieces evenly distributed along the circumferential direction at the bottom.

[0016] The utility model has the following beneficial effects:

[0017] When the side guide body is installed, the bottom contour of the pin hole is larger than the positioning pin shaft, which makes loading and unloading smoother; when the side guide body descends until the abutment surface abuts against the upper surface of the cantilever seat, and then continues to descend, the cantilever seat will drive the centering piece to rotate, and drive the centering fitting surface to move toward the peripheral wall of the positioning pin shaft until the centering fitting surface is in close contact with the peripheral wall of the positioning pin shaft, eliminating the installation gap between the bottom of the pin hole and the positioning pin shaft, ensuring the installation accuracy of the side guide body, and ensuring accurate guidance of the steel coil.

[0036] Please refer to Figure 1 and Figure 2 In a preferred embodiment of the present invention, an automatically centered side guide assembly includes a cantilever seat 100, a side guide body 200 and a centering piece 300.

[0037] The cantilever seat 100 is provided with a positioning pin 110 protruding from the upper surface of the cantilever seat 100; the side guide body 200 is provided with two and spaced apart, specifically, the side guide body 200 is spaced apart in a direction perpendicular to the conveying direction, so as to guide and limit the conveying of the steel coil. The bottom of the side guide body 200 is supported by the cantilever seat 100, and the side guide body 200 is provided with a positioning cylinder 210 corresponding to the positioning pin 110, and the center of the positioning cylinder 210 is provided with a pin hole 211 for inserting the positioning pin 110, and the bottom contour of the pin hole 211 is larger than the positioning pin 110. There are multiple centering pieces 300 arranged around the center of the positioning cylinder 210, and the centering pieces 300 are hinged at the bottom of the positioning cylinder 210. The centering piece 300 has a contact surface 301 and a centering fitting surface 302. The contact surface 301 contacts the upper surface of the cantilever seat 100, and the centering fitting surface 302 contacts the peripheral wall of the positioning pin shaft 110. When the contact surface 301 contacts the upper surface of the cantilever seat 100, the contact surface 301 is subjected to an upward pushing force from the cantilever seat 100. The pushing force causes the centering piece 300 to rotate and drive the centering fitting surface 302 to contact the peripheral wall of the positioning pin shaft 110, thereby further eliminating the installation gap between the bottom of the positioning pin shaft 110 and the bottom of the pin hole 211.

[0038] The utility model provides a side guide assembly that can be automatically centered. When the side guide body 200 is installed, the bottom contour of the pin hole 211 is larger than the positioning pin shaft 110, so that loading and unloading are smoother; when the side guide body 200 descends until the abutment surface 301 abuts against the upper surface of the cantilever seat 100, and then continues to descend, the cantilever seat 100 will drive the centering piece 300 to rotate, and drive the centering fitting surface 302 to move toward the peripheral wall of the positioning pin shaft 110 until the centering fitting surface 302 is tightly attached to the peripheral wall of the positioning pin shaft 110, thereby eliminating the installation gap between the bottom of the pin hole 211 and the positioning pin shaft 110, and ensuring the installation accuracy of the side guide body.

[0039] Reference Figure 3 and Figure 4 In some embodiments of the utility model, the side guide body 200 is provided with an embedding hole 221 for the positioning tube 210 to be embedded, and the surrounding wall of the embedding hole 221 is provided with a threaded hole 222, and the surrounding wall of the positioning tube 210 is provided with a fixing hole 212 aligned with the threaded hole 222, and the threaded hole 222 is threadedly connected with a fixing screw 223, and the fixing screw 223 is partially inserted into the fixing hole 212, so as to realize the connection and fixation between the positioning tube 210 and the side guide body 200, and the positioning tube 210 can be positioned by inserting the fixing screw 223 into the fixing hole 212, thereby improving the installation accuracy.

[0040] Reference Figure 3 and Figure 4In a further embodiment of the utility model, a groove 224 is provided at the bottom of the side guide body 200, and an embedding hole 221 is formed on the top wall of the groove 224; a mounting seat 230 embedded in the groove 224 is provided at the bottom of the positioning cylinder 210, and the groove 224 is adapted to the contour of the mounting seat 230; the mounting seat 230 partially protrudes from the peripheral wall of the positioning cylinder 210 to fit with the bottom of the side guide body 200, thereby playing a certain role in limiting the height direction, and the centering piece 300 is hinged to the mounting seat 230, and the mounting seat 230 is provided with an installation position for the centering piece 300 to be embedded, and the centering piece 300 and the side wall of the installation position are provided with corresponding holes to realize the hinge connection through the hinge axis. When the abutting surface 301 abuts against the upper surface of the cantilever seat 100, the bottom surface of the mounting seat 230 is flush with the abutting surface 301, so that when installed, the bottom surface of the mounting seat 230 will not affect the contact and cooperation between the abutting surface 301 and the cantilever seat 100. The mounting seat 230 provides a better hinged mounting position for the centering member 300 , and the mounting seat 230 is embedded in the groove 224 to avoid protruding from the bottom of the side guide body 200 .

[0041] Reference Figure 3 and Figure 4 In a further embodiment of the utility model, a positioning groove 220 is provided at the bottom of the side guide body 200 for the cantilever seat 100 to partially embed, thereby improving the installation positioning accuracy with the cantilever seat 100 and effectively dispersing the load to avoid the load being concentrated on the positioning pin 110. A groove 224 is formed on the top wall of the positioning groove 220; when the abutting surface 301 abuts against the upper surface of the cantilever seat 100, the abutting surface 301 is flush with the top wall of the positioning groove 220, so that the positioning groove 220 does not interfere with the cooperation between the abutting surface 301 and the cantilever seat 100.

[0042] Reference Figure 3 and Figure 4 In a further embodiment of the utility model, the centering member 300 includes a hinged portion 310, an abutting portion 320 and a centering portion 330. The hinged portion 310 is hinged to the mounting seat 230. The abutting portion 320 and the centering portion 330 are connected to the hinged portion 310. The abutting surface 301 is formed on the abutting portion 320. Specifically, the abutting portion 320 has a boss on the outside. The abutting portion 320 is specifically formed on the boss on the outside of the abutting portion 320. The boss makes the position where the abutting portion 320 fits with the positioning pin shaft 110 protrude, and the other positions converge inward to reduce the possibility of structural interference. The centering fitting surface 302 is formed on the centering portion 330. The abutment portion 320 and the centering portion 330 extend radially outward along the hinge center, and the abutment portion 320 and the centering portion 330 are perpendicular, so that when the abutment surface 301 of the centering piece 300 abuts against the upper surface of the cantilever seat 100, the centering fitting surface 302 will fit against the peripheral wall of the positioning pin shaft 110.

[0043] Reference Figure 3 and Figure 4In a further embodiment of the present invention, a side wall of the groove 224 is provided with an avoidance groove 225 corresponding to the abutment portion 320, so as to avoid structural interference.

[0044] Reference Figure 5 In a further embodiment of the present invention, the side wall of the groove 224 is used to abut against the side of the centering portion 330 facing away from the centering fitting surface 302, so as to limit one of the end points of the rotation range of the centering member 300, that is, to limit the end point of the rotation of the centering member 300 in the counterclockwise direction. Figure 5 As shown, under the action of gravity, the side wall of the groove 224 abuts against the side of the centering portion 330 facing away from the centering fitting surface 302. At this time, the centering piece 300 is in an open state, which is convenient for the insertion of the positioning pin 110, and at the same time, the abutting portion 320 partially protrudes out of the groove 224; the limiting effect of the side wall of the groove 224 can effectively prevent the centering piece 300 from rotating at will, which will cause the abutting surface 301 and the centering fitting surface 302 to fail to perform the corresponding functions as set. During installation, the positioning pin 110 can be smoothly inserted until the upper surface of the cantilever seat 100 begins to contact the abutting surface 301. The upward movement of the cantilever seat 100 can drive the centering fitting surface 302 to move closer to the positioning pin 110, until it is in close contact with the surrounding wall of the positioning pin 110, reaching Figure 6 The state shown eliminates the installation gap and improves the installation accuracy without affecting the smoothness of installation and disassembly.

[0045] In a further embodiment of the present invention, the top wall of the avoidance groove 225 is used to abut against the side of the abutment portion 320 facing away from the abutment surface 301, so as to limit the other end point of the rotation range of the centering member 300, that is, to limit the end point of the clockwise rotation of the centering member 300. The top wall of the avoidance groove 225 can well control the rotation range of the centering member 300 and the posture at the end point of the stroke, such as Figure 7 As shown, although the centering portion 330 partially protrudes from the peripheral wall of the pin hole 211, the centering portion 330 is inclined toward the center of the upper pin hole 211 and hardly affects the insertion of the pin shaft.

[0046] Reference Figure 1 In some embodiments of the present invention, a plurality of lifting ears 240 are provided at the upper end of the side guide body 200 to facilitate lifting.

[0047] In some embodiments of the present invention, each side guide body 200 is provided with at least two positioning cylinders 210, wherein at least one positioning cylinder 210 has four centering pieces 300 evenly distributed along the circumferential direction at the bottom. Figure 1As shown, each side guide body 200 is provided with two positioning cylinders 210, wherein four centering pieces 300 are evenly distributed along the circumference at the bottom of one positioning cylinder 210, and two centering pieces 300 are evenly distributed along the circumference at the bottom of the other positioning cylinder 210, and the spacing distribution direction of the two centering pieces 300 is perpendicular to the conveying direction, thereby ensuring the lateral accuracy of the side guide body 200 and the guiding accuracy of the steel coil.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
