Description

Technical Field

[0001] This utility model relates to the field of rolling mill auxiliary equipment technology, and in particular to an adjustable rolling mill guide device. Background Technology

[0002] The guide device is installed at the inlet and outlet of the universal rolling mill and is an important component of the rolling process. As a continuation of the roll pass in the rolling process, it plays a crucial role in controlling the shape and guiding the workpiece.

[0003] Guide devices are generally manufactured on a one-machine-one-model basis because each rolling mill has a different pass profile, resulting in variations in the guide devices used for each mill. This causes significant inconvenience in the manufacturing, management, and storage of guide devices. Furthermore, since most guide devices are directly welded from steel plates, the subsequent micro-processing after manufacturing is extremely cumbersome, and dimensional control is difficult. Therefore, an adjustable guide device for rolling mills is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable guide device for rolling mills. The distance between two guide plates is adjusted by a first hydraulic push rod, the overall height is adjusted by a second hydraulic push rod driving a U-shaped support plate to rise and fall, and the limit seat is moved by a third hydraulic push rod. This device can accurately align with the inlet and outlet of different rolling mills, eliminating the need to manufacture guides for each rolling mill individually. This significantly reduces the cost and inconvenience of guide manufacturing, management, and storage, and overcomes the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable guide device for a rolling mill includes a base plate, a lifting assembly mounted on the base plate, a support frame fixed on the lifting assembly, an adjustment assembly and a limiting assembly mounted on the support frame, and connection holes provided at the four corners of the base plate.

[0007] The adjusting assembly includes two symmetrically arranged first hydraulic push rods, each with a guide plate connected to one end of its opposite side.

[0008] As a further embodiment of this utility model: the lifting assembly includes a U-shaped support plate movably mounted on the base plate, with the vertical sections on both sides of the U-shaped support plate movably inserted into both ends of the base plate, and a second hydraulic push rod installed between the top of the base plate and the middle of the lower end face of the horizontal section of the U-shaped support plate.

[0009] As a further embodiment of this utility model: the support frame includes a support plate fixed to the upper end face of the horizontal section of the U-shaped support plate, and side plates are fixed on both sides of the upper end face of the support plate, and a top plate is fixed to the top of the two side plates.

[0010] As a further embodiment of this utility model: the limiting component includes a third hydraulic push rod fixed on the top plate, the lower end of the third hydraulic push rod extending to the bottom of the top plate and connected to a lifting plate, and the lower end of the lifting plate connected to a limiting seat.

[0011] As a further improvement of this utility model: sliders are fixed at both ends of the lifting plate, and strip holes are provided on the top of the two side plates. The two sliders are slidably engaged with the two strip holes respectively.

[0012] As a further improvement of this utility model: a U-shaped support frame is connected to the back of each of the two guide plates, and the two U-shaped support frames are slidably inserted into the two side plates respectively.

[0013] As a further improvement of this utility model: the top of both guide plates is provided with a bending part, and the bottom of the opposite ends of the limiting seat is provided with an inclined part.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The distance between the two guide plates is adjusted by the first hydraulic push rod, the U-shaped support plate is raised and lowered by the second hydraulic push rod to adjust the overall height, and the limit seat is moved by the third hydraulic push rod. It can accurately align with the inlet and outlet of different rolling mills, eliminating the need to make guides for each rolling mill separately, which greatly reduces the cost and inconvenience of guide manufacturing, management and storage.

[0016] 2. The U-shaped support frame on the back of the guide plate enhances the support stability. The sliding block of the lifting plate and the strip hole of the side plate cooperate to ensure the smooth lifting of the limit seat. The bent part of the guide plate and the inclined part of the limit seat avoid collision and damage, ensuring the stable operation of the device and improving the safety of the rolling mill guiding and limiting process.
