Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel rolling, in particular to a special-shaped steel rolling mill guide mechanism. BACKGROUND

[0002] Steel rolling is a metal processing technology that uses rotating rollers to compress metal materials, reducing their cross-section and increasing their length to achieve the desired shape and size. This process can be divided into hot rolling and cold rolling, and is widely used in the production of profiles, plates and pipes. Hot rolling is suitable for mass production of high-precision products, and can refine the grain and improve the mechanical properties. Cold rolling is used for more precise surface treatment and size control.

[0003] According to the Chinese patent with the announcement number CN210333780U, the special-shaped steel rolling mill guide mechanism includes a vertically arranged support frame. The support frame has an upper support shaft and a lower support shaft. The two ends of the upper support shaft and the lower support shaft are connected to the two vertical edge frames of the support frame. The upper support shaft has an upper limit roller, which is rotationally connected to the upper support shaft. The lower support shaft has a lower limit roller, which is rotationally connected to the lower support shaft. The upper limit roller and the lower limit roller are arranged in an upper and lower side-by-side manner. The two ends of the lower support shaft are fixed to the lower part of the two vertical edge frames of the support frame. The inner side wall of the upper part of the two vertical edge frames of the support frame has a vertical sliding groove. The vertical sliding groove has a screw. The lower end of the screw is connected to the bottom of the vertical sliding groove. The upper end of the screw extends from the top of the vertical sliding groove to above the support frame through the vertical edge frame of the support frame. The screw and the support frame are rotationally connected in an axial and circumferential manner. The two ends of the upper support shaft are located in the two vertical sliding grooves. The upper support shaft and the vertical sliding groove are slidingly connected in an upper and lower manner. The upper support shaft of the corresponding screw has a screw hole. The upper support shaft is sleeved on the screw through the screw hole, so that the screw is rotated and the upper support shaft moves up and down. The upper ends of the two screws have a linkage mechanism.

[0004] In the above-mentioned scheme, the support frame provides a processing space for the rolling of steel, which still has the following disadvantages: during the rolling process of the steel, a large amount of steel chips will fall due to deformation. These steel chips fall on the inner bottom surface of the support frame and are not easy to recover, increasing the loss rate of the steel. Utility model content

[0005] The utility model aims to provide a special-shaped steel rolling mill guide mechanism to solve the problem of the loss rate of the steel increasing due to the large amount of steel chips falling during the rolling process of the steel.

[0006] In order to realize the above-mentioned utility model purposes, the utility model adopts the following technical scheme: a special-shaped steel rolling mill guide mechanism, including two fixed plates, the two fixed plates are fixed on the top surface of a workbench, a lower roller is rotatably arranged between the two fixed plates, a lifting plate is slidably arranged above the fixed plate, an upper roller is rotatably arranged between the two lifting plates, a storage frame is slidably arranged on the top surface of the workbench, a sliding opening is formed in the top surface of the workbench, a first motor is fixed on one side of the workbench, the output shaft of the first motor penetrates through the workbench and extends into the inside of the sliding opening, a threaded rod is rotatably arranged in the inside of the sliding opening, a threaded pipe is threadedly connected to the threaded rod, the top surface of the threaded pipe is detachably arranged with the bottom surface of the storage frame, and two guide plates are fixed on the top surface of the storage frame.

[0007] Preferably, a positioning hole is formed in the inside bottom surface of the storage frame, a dismounting pipe is fixed on the top surface of the threaded pipe, and the positioning hole and the dismounting pipe are slidably inserted.

[0008] Preferably, an adjusting plate is detachably arranged on one side of the guide plate, a plurality of fixing holes are formed in one side of the guide plate, a fixing bolt is rotatably inserted into the inside of the fixing hole, and one end of the fixing bolt penetrates through the fixing hole and is threadedly connected with the adjusting plate.

[0009] Preferably, a plurality of stabilizing holes are formed in one side of the guide plate, and two stabilizing rods are fixed on one side of the adjusting plate.

[0010] Preferably, two threaded columns are fixed on the top surface of the fixed plate, the threaded columns are slidably inserted with the lifting plate, two heightening pads are arranged on the top surface of the fixed plate, the threaded columns are slidably inserted with the heightening pads, two nuts are arranged above the lifting plate, and the threaded columns are threadedly connected with the nuts.

[0011] Preferably, a second motor is fixed on the bottom surface of the workbench, a driving wheel is fixedly inserted into the output shaft of the second motor, a driven wheel is fixed on one end of the lower roller, a transmission belt is wrapped around the driven wheel, and the inner wall surface of the transmission belt is attached to the surface of the driving wheel.

[0012] Compared with the prior art, the special-shaped steel rolling mill guide mechanism adopting the above technical scheme has the following beneficial effects:

[0013] One, the staff will send steel between the lower roller and the upper roller, and then the output shaft of the first motor rotates the threaded rod synchronously. The threaded rod pushes the storage frame to slide left and right on the top surface of the workbench during rotation by using the threaded connection with the threaded pipe, and drives the guide plate to slide synchronously during left and right sliding, and applies a transverse pushing force to one end of the steel during sliding, that is, the steel is pushed back and forth between the lower roller and the upper roller. The steel scrap falling during rolling falls into the inside of the storage frame, so that the falling steel scrap can be recycled, reducing the loss of steel;

[0014] Two, when rolling special-shaped steel, the staff will change the position of the adjusting plate on the guide plate in advance according to the size and shape of the special-shaped steel. When adjusting, the staff will first unscrew the fixing bolt from the adjusting plate, then the staff will move the adjusting plate upwards or downwards, and after determining the position, the staff will screw the fixing bolt into the adjusting plate again, and insert the stabilizing rod into the stabilizing hole. Increase the stability of the position of the adjusting plate on the guide plate, and increase the guiding effect of the adjusting plate with adjustable position on different shapes of special-shaped steel;

[0015] Three, before rolling steel with different diameters, the staff will first adjust the number of height pads between the fixed plate and the lifting plate according to the diameter of the steel, that is, the height of the lifting plate above the fixed plate can be adjusted. Then the staff uses the downward rotation of the lifting plate top surface nut to apply a downward force to the lifting plate, which can increase the firmness of the lifting plate on the top surface of the fixed plate. After adjustment, different diameter steels can be rolled, increasing the application range of steel rolling. BRIEF DESCRIPTION OF DRAWINGS
