Description

Technical Field

[0001] The present application relates to the technical field of steel processing devices, and in particular to a roller spacing adjustment device for steel production. Background Art

[0002] The roller is mainly composed of three parts: the roller body, the roller neck and the shaft head. The roller body is the middle part of the roller that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roller neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The shaft head at the transmission end is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roller. The rollers can be arranged in the form of two rollers, three rollers, four rollers or multiple rollers in the rolling mill frame.

[0003] During processing, the rollers are driven by motors to rotate, and the steel plate is placed in the gap between the two rollers to achieve rolling processing of the steel plate. In order to adapt to the rolling of steel plates of different specifications and thicknesses, it is necessary to adjust the spacing between the upper and lower rollers. Most of the common adjustment devices currently use hydraulic cylinders in conjunction with guide rails. Although they can be adjusted, it is inconvenient for the adjustment staff to know the spacing changes in real time, and the adjustment accuracy is poor. Multiple adjustments are required, which brings inconvenience to the adjustment process.

[0004] Therefore, those skilled in the art provide a roller spacing adjustment device for steel production to solve the problems raised in the above background technology. Utility Model Content

[0007] A roller spacing adjustment device for steel production comprises a support base, a mounting plate, a lower roller and an upper roller, wherein one end of the outer side of the lower roller and the upper roller are rotatably connected to a support shaft, and the opposite ends of the two support shafts are fixedly connected to positioning plates, and the two positioning plates are respectively attached to the tangents of the upper roller and the lower roller, and a scale mark rod is installed on one side of the upper surface of the support base, and the outside of the scale mark rod passes through the two positioning plates in sequence.

[0008] Preferably, guide rods are fixed to the four corners of the upper surface of the support base, a top plate is installed between the tops of the four guide rods, hydraulic cylinders are installed on both sides of the lower surface of the top plate, a cross plate is installed between the bottoms of the two hydraulic cylinders, upper roller frames are fixed on both sides of the lower surface of the cross plate, and the interior of the upper roller frame is rotatably connected to the outside of the upper rolling roller.

[0010] Preferably, lower roller frames are installed on both sides of the upper surface of the mounting plate, and the interiors of the lower roller frames on both sides are rotatably connected to the two ends of the lower rolling roller.

[0011] Preferably, a fixing plate is fixed to one side of the upper surface of the support base, a driving motor is installed above the fixing plate, and an output end of the driving motor is fixed to a corresponding end of the lower rolling roller.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The upper positioning plate is driven by the movable support shaft to move longitudinally on the scale bar, and the upper and lower positioning plates are respectively parallel to the upper and lower tangents of the lower roller and the upper roller. Therefore, the spacing value of the lower roller and the upper roller can be accurately reflected by the spacing value of the upper and lower positioning plates. Then, during the overall adjustment process, the accurate value of the lower and upper rollers during adjustment can be known in real time by observing the moving position of the positioning plate on the scale bar, which greatly reduces the number of adjustments required by the staff and brings convenience to the staff during adjustment.

A support shaft 14 is rotatably connected to one end of the outer side of the lower roller 3 and the upper roller 7. Positioning plates 15 are fixedly connected to the opposite ends of the two support shafts 14. The two positioning plates 15 are respectively attached to the tangents of the upper roller 7 and the lower roller 3, which will not affect the normal rotation of the lower roller 3 and the upper roller 7. At the same time, the spacing value of the lower roller 3 and the upper roller 7 can be reflected by the spacing value of the upper and lower positioning plates 15. At the same time, a scale mark rod 13 is installed on one side of the upper surface of the support base 1, and the outside of the scale mark rod 13 passes through the two positioning plates 15 in sequence. By observing the moving position of the positioning plate 15 on the scale mark rod 13, the accurate value of the lower roller 3 and the upper roller 7 when adjusted can be known in real time, which greatly reduces the number of adjustments required by the staff.

The plurality of guide rods 9 cooperate with the top plate 6 to provide stability for the hydraulic cylinder 5 installed above the mounting plate 2. At the same time, hydraulic cylinders 5 are installed on both sides of the lower surface of the top plate 6, and a cross plate 8 is installed between the bottoms of the two hydraulic cylinders 5. Upper roller frames 10 are fixed on both sides of the lower surface of the cross plate 8, and the upper roller frames 10 are internally matched with bearings to achieve external rotation connection with the upper roller 7. The cross plate 8 and the upper roller frame 10 are driven to move by starting the hydraulic cylinder 5, and then the upper roller frame 10 can drive the upper roller 7 to realize longitudinal movement and adjust the spacing value between the upper roller 7 and the lower roller 3.

[0022] refer to Figure 1 and Figure 2 As shown, two guide rods 9 on the same side respectively penetrate the two ends of the upper roller frame 10, so that the upper roller frame 10 can move along the track of the guide rods 9, thereby improving the stability of the longitudinal movement of the upper roller 7.

[0023] refer to Figure 1 and Figure 2 As shown, lower roller frames 4 are installed on both sides of the upper surface of the mounting plate 2, and the lower roller frames 4 on both sides are rotatably connected with the lower rolling roller 3 through bearings, so as to facilitate the lower rolling roller 3 to move stably above the mounting plate 2.

[0024] refer to Figure 1 and Figure 2 As shown, a fixing plate 12 is fixed to one side of the upper surface of the support base 1, and a driving motor 11 is installed above the fixing plate 12, and the output end of the driving motor 11 is fixed to the corresponding end of the lower roller 3. By starting the support base 1, the output end of the support base 1 can drive the lower roller 3 to rotate, which is convenient for cooperation with the upper roller 7 to realize the processing of the steel plate.
