Description

Technical Field

[0001] This utility model relates to an imported rolling guide that can precisely adjust the lateral displacement of imported steel, belonging to the technical field of rolling mill equipment in the metallurgical industry. Background Technology

[0002] Guides are divided into inlet guides and outlet guides. Inlet guides are installed at the entrance of the rolling mill to ensure the workpiece enters the mill smoothly and completes the biting process. Outlet guides are installed at the exit of the rolling mill to ensure the workpiece maintains the correct orientation and smoothly exits the groove as it exits the rolls, thereby guaranteeing machine output and product quality. The smaller the workpiece, the more precise the machining and installation of the guides should be.

[0003] Guides are further divided into rolling guides and sliding guides. Sliding guides are easier to control the direction of the rolled piece, but the rolled piece is prone to scratches. Rolling guides mainly rely on rollers arranged in an alternating pattern to control the direction of the rolled piece. This traditional imported rolling guide can accurately control the vertical oscillation of the steel, but it cannot adjust the lateral displacement of the steel, affecting the stable rolling during the mill's bite, thus affecting the cross-sectional dimensions and shape of the finished product. For example, angle steel has the most stringent requirements for the accuracy of its side length, thickness, and apex angle. During the rolling process of angle steel, relying solely on rollers arranged in an alternating pattern to control the direction of the rolled piece cannot ensure that the rolled piece accurately bites into the mill to achieve stable rolling. This can easily cause one side of the angle steel to exceed the specified upper limit and the other side to exceed the specified lower limit, affecting the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to provide an imported rolling guide that can precisely adjust the lateral displacement of imported steel, so that the rolled piece can be rolled stably after biting in, ensuring the cross-sectional dimensions and shape, so that the final product meets the quality requirements, and solving the problems existing in the background technology.

[0005] The technical solution of this utility model is:

[0006] An inlet rolling guide capable of precisely adjusting the lateral displacement of imported steel includes a rolling mill channel consisting of a horn-shaped inlet, a right baffle, a left baffle, and a bottom plate, and several rollers arranged vertically and alternately within the rolling mill channel. A left displacement plate and a right displacement plate, which cooperate with the rolling mill, are also provided within the rolling mill channel. The left displacement plate and the left baffle are connected by several left displacement adjusting screws, and the right displacement plate and the right baffle are connected by several right displacement adjusting screws.

[0007] The left displacement plate and the right displacement plate are arranged between the left baffle and the right baffle.

[0008] The left displacement plate is close to the left baffle, and the right displacement plate is close to the right baffle.

[0009] The distance between the left and right displacement plates is matched with the workpiece.

[0010] The distance between the left and right displacement plates narrows as the rolling mill moves in the direction of travel.

[0011] The beneficial effects of this invention are: it enables stable rolling of the workpiece after it bites in, ensuring cross-sectional dimensions and shape, and ensuring the final product meets quality requirements. It also reduces steel pile-up accidents and improves the yield rate of the production line. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and examples.

[0017] See attached document Figure 1-3 An inlet rolling guide capable of precisely adjusting the lateral displacement of inlet steel includes a rolling mill channel consisting of a horn-shaped inlet 1, a right baffle 2, a left baffle 3, and a bottom plate 4, and several rollers arranged vertically and alternately within the rolling mill channel. A left displacement plate 5 and a right displacement plate 7, which cooperate with the rolling mill, are also provided within the rolling mill channel consisting of the horn-shaped inlet 1, the right baffle 2, the left baffle 3, and the bottom plate 4. The left displacement plate 5 and the left baffle 3 are connected by several left displacement adjusting screws 6, and the right displacement plate 7 and the right baffle 2 are connected by several right displacement adjusting screws 8.

[0018] In this embodiment, refer to the appendix Figure 1-3 The imported rolling guide is installed at the inlet of the rolling mill. There are three rollers arranged alternately in the rolling passage consisting of the trumpet inlet 1, the right baffle 2, the left baffle 3, and the bottom plate 4. These include the upper contact roller 9, the lower rear roller 10, and the lower front roller 11. After the steel passes through the trumpet inlet 1, the three rollers arranged alternately can precisely control the up and down swing of the rolling piece.

[0019] A left displacement plate 5 and a right displacement plate 7 are added between the left baffle 3 and the right baffle 2. The left displacement plate 5 and the left baffle 3 are connected by several left displacement adjusting screws 6, and the right displacement plate 7 and the right baffle 2 are connected by several right displacement adjusting screws 8. By adjusting the left displacement adjusting screws 6 and the right displacement adjusting screws 8, the distance between the left displacement plate 5 and the right displacement plate 7 can be adjusted, so that the distance between the left displacement plate 5 and the right displacement plate 7 becomes wider or narrower according to the running direction of the rolled piece.

[0020] During the production of angle steel, when the final finished product's cross-sectional dimensions and shape meet the relevant standards, the left displacement plate 5 and the right displacement plate 7 maintain a symmetrical state and do not interfere with the lateral displacement of the steel.

[0021] When the final product's cross-sectional dimensions and shape do not meet the relevant standards, such as one side length exceeding the upper limit and the other side length exceeding the lower limit, the relative positions of the left displacement plate 5 and the right displacement plate 7 are adjusted by adjusting the left displacement adjusting screw 6 and the right displacement adjusting screw 8 to interfere with the lateral displacement of the steel material, so that the final product's cross-sectional dimensions and shape meet the relevant standard requirements.
