Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill frames, in particular to a rolling mill frame. Background Art

[0002] A rolling mill is a device that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. According to the number of rollers, rolling mills can be divided into two-roller, four-roller, six-roller, eight-roller, twelve-roller, eighteen-roller, etc.; according to the arrangement of rollers, they can be divided into "L" type, "T" type, "F" type, "Z" type and "S" type. The frame is an indispensable part of the rolling mill, which is mainly used to install rollers and other parts.

[0003] At present, the frame on the rolling mill is mainly composed of a base, upright frames symmetrically formed on both sides of the upper end of the base, and bearing seat mounting grooves opened on the upright frames. Although the rolling mill frame with the above structure can realize the convenient installation of the bearing mounting seat and rollers and other components on the rolling mill when in use, on the one hand, since the spacing between the two upright frames on the rolling mill frame with the above structure is fixed and cannot be adjusted, it is necessary to perform cumbersome tilting and rotating operations when installing the rollers on the rolling mill frame, which makes the efficiency of roller installation relatively low. On the other hand, since the installation position of the rollers on the upright frames is fixed, the spacing between the rollers after installation cannot be adjusted according to actual use needs, resulting in poor flexibility in the use of the rolling mill frame. Utility Model Content

Two electric hydraulic rods are symmetrically installed on both sides of the upper end of each of the two mounting brackets, and the top of the electric hydraulic rod on each of the two mounting brackets is connected with an upper mounting bracket. There are two upper mounting brackets, and two guide telescopic rods are symmetrically and parallelly installed between the two upper mounting brackets.

[0008] Furthermore, a mounting groove is provided in the middle of the upper end of the lower mounting frame and in the middle of the bottom end of the upper mounting frame.

[0009] By adopting the above technical solution, the mounting groove is mainly used to realize the installation and fixation of the bearing mounting seat on the rolling mill, so as to ensure the subsequent convenient installation and fixation of the rolling roller.

[0010] Furthermore, the bidirectional threaded rod is threadedly connected to the slider, and the bidirectional threaded rod passes through the slider.

[0011] By adopting the above technical solution, after the bidirectional threaded rod rotates, the two sliders can be synchronously moved under the action of thread transmission, so as to adjust the distance between the two upper mounting frames according to actual installation needs.

[0012] Furthermore, the bidirectional threaded rod is rotatably connected to the base, and the motor is connected to the bidirectional threaded rod via a coupling.

[0013] By adopting the above technical solution, the motor is mainly used to provide power for the rotation of the bidirectional threaded rod.

[0014] Furthermore, the sliding rod is slidably connected to the sliding hole, and the sliding rod is bolted to the vertical plate.

[0015] By adopting the above technical solution, the cooperation between the slide rod and the slide hole is mainly used to ensure the smooth sliding of the lower mounting frame during adjustment.

[0016] Furthermore, the fixed part of the guide telescopic rod is bolted to one of the upper mounting frames, the telescopic part of the guide telescopic rod is bolted to the other upper mounting frame, and the guide telescopic rod is composed of a sleeve rod and a telescopic rod slidably installed in the sleeve rod.

[0017] By adopting the above technical solution, the guide telescopic rod is mainly used to ensure the structural strength between the two upper mounting frames and ensure convenient sliding between the two upper mounting frames.

[0018] Furthermore, the fixing portion of the electric hydraulic rod is connected to the lower mounting frame by bolts, and the telescopic portion of the electric hydraulic rod is connected to the upper mounting frame by bolts.

[0019] By adopting the above technical solution, the electric hydraulic rod will drive the upper mounting frame to move upward after being started, so as to adjust the spacing between the rollers according to actual use needs, thereby improving the use flexibility of the rolling mill frame.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the frame on the current rolling mill is mainly composed of a base, vertical frames symmetrically formed on both sides of the upper end of the base and bearing seat mounting grooves opened on the vertical frames, the rolling mill frame with the above structure can realize the convenient installation of the bearing mounting seat and rollers and other components on the rolling mill when in use, but on the one hand, since the spacing between the two vertical frames on the rolling mill frame with the above structure is fixed and cannot be adjusted, it is necessary to perform cumbersome tilting and rotating operations when the rollers are installed on the rolling mill frame, which makes the efficiency of roller installation relatively low. On the other hand, since the installation position of the rollers on the vertical frames is fixed, the spacing of the rollers after installation cannot be adjusted according to actual use needs, resulting in the use of the rolling mill frame. In order to solve the problem of poor flexibility, the utility model can, on the one hand, realize convenient adjustment of the distance between the two upper mounting frames under the action of the motor, the bidirectional threaded rod, the slide groove, the slider, the slide rod, the slide hole and the guide telescopic rod. Such a design can effectively avoid the rotation and tilting operation of the rollers during installation, and ensure that the rollers can be directly placed flat between the two upper mounting frames and the two lower mounting frames for installation during installation, thereby greatly improving the installation efficiency. On the other hand, with the help of an electric hydraulic rod, the adjustment of the distance between the upper mounting frame and the lower mounting frame can be achieved, thereby ensuring that the rolling mill frame can be used according to actual needs to realize the adjustment of the distance between the rollers after installation, thereby improving the flexibility of use of the rolling mill frame.
