Description

Technical Field

[0001] This utility model relates to the technical field of hot-rolled steel plate processing, specifically a hot-rolled steel plate roughing mill. Background Technology

[0002] Hot-rolled steel plate processing uses continuously cast slabs or primary rolled slabs as raw materials. After being heated in a walking beam furnace and descaled by high-pressure water, the slabs enter the roughing mill. The rough-rolled material is then cut at the head and tail and enters the finishing mill, where computer-controlled rolling is implemented. After final rolling, the slabs undergo laminar flow cooling and are coiled by a coiler to become straight coils. The head and tail of straight coils are often tongue-shaped or fishtail-shaped, and the thickness and width accuracy are relatively poor. The edges often have defects such as waviness, folding, and tapering. The roughing mill is an indispensable machine in the hot-rolled steel plate processing.

[0003] The patent with publication number CN221537636U discloses a hot-rolled steel plate roughing mill for improving processing accuracy. It includes a support base, a frame fixed above the support base, a positioning groove on the front surface of the frame, a guide groove on the inner surface of the frame, a guide block installed inside the guide groove, an upper bearing seat fixed to one side of the guide block, and a sleeve fixed above the upper bearing seat. This hot-rolled steel plate roughing mill for improving processing accuracy utilizes the coordinated use of the guide groove, guide block, sleeve, threaded rod, drive motor, fixed frame, and damping reset rod. The drive motor drives the threaded rod to rotate, thereby causing the upper bearing seat to rise and fall. During the rising and falling of the upper bearing seat, the guide groove and guide block improve the stability of the upper bearing seat, thus improving the processing accuracy of the hot-rolled steel plate. Furthermore, the damping reset rod buffers the upper bearing seat, facilitating precise control of the hot-rolled steel plate thickness.

[0004] However, the roughing mill in the above technology still has the following problems during use:

[0005] Since the mounting plate and the roll are connected by multiple bolts, each bolt needs to be installed or removed individually using tools when installing or removing the roll. This process is quite cumbersome and causes inconvenience to the installation or removal of the roll. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a hot-rolled steel plate roughing mill, which makes the installation or disassembly of the rolls more convenient.

[0007] A hot-rolled steel plate roughing mill includes a main body, which includes a mounting plate and rolls. A plurality of insert rods are fixedly connected to the side of the mounting plate near the rolls, and slots for inserting the insert rods are provided on the rolls.

[0008] Preferably, an iron plate is fixedly connected to the bottom of the slot, and a magnet that can contact the iron plate is connected to one end of the insertion rod that is inserted into the slot.

[0009] Preferably, a groove is formed on the peripheral side of the insertion rod, a spring is fixedly connected to the bottom of the groove, and a sliding rod that can slide in the groove is fixedly connected to the other end of the spring. The end of the sliding rod away from the spring is hemispherical.

[0010] Preferably, a limiting ring is connected to the opening of the groove to limit the movement of the slide rod, and the inner diameter of the limiting ring is smaller than the diameter of the upper hemisphere of the slide rod.

[0011] Preferably, the cross-section of the insertion rod is polygonal, and the corresponding slot is a polygonal shape that matches the insertion rod.

[0012] Preferably, the insertion rods are evenly distributed in a ring on the mounting plate.

[0013] Preferably, the mounting plate has a snap-fit ​​groove on its peripheral side.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This type of hot-rolled steel plate roughing mill, by setting up insert rods and slots, allows the connection between the mounting plate and the roll to be completed by inserting the insert rod into the slot when it is necessary to connect the mounting plate and the roll. The entire installation or disassembly operation process is simple, which facilitates daily work and improves work efficiency.

[0016] 2. This type of hot-rolled steel plate roughing mill has an iron plate fixedly connected to the bottom of the slot, and a magnet that can contact the iron plate is connected to one end of the insertion rod inserted into the slot. After the insertion rod is inserted into the slot, the magnetic attraction between the iron plate and the magnet increases the connection force between the mounting plate and the roll, thus preventing the roll from shaking between the mounting plates.

[0017] 3. This hot-rolled steel plate roughing mill has a groove on the circumferential side of the insert rod, and a sliding rod is movably connected in the groove by a spring. When the insert rod is inserted into the slot, the sliding rod will abut against the inner wall of the slot under the elastic force of the spring. This increases the stability of the insert rod connection in the slot on the basis of iron sheet and magnet. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 3 As shown, a hot-rolled steel plate roughing mill includes a roughing mill body 1. The roughing mill body 1 includes a mounting plate 2 and a roll 3. A plurality of insert rods 4 are fixedly connected to the side of the mounting plate 2 near the roll 3. The roll 3 has slots 5 for inserting the insert rods 4.

[0025] Specifically, by setting up the insertion rod 4 and the slot 5, when it is necessary to connect the mounting plate 2 and the roller 3, the insertion rod 4 is inserted into the slot 5 to complete the connection between the mounting plate 2 and the roller 3. The entire installation or disassembly operation process is simple, which facilitates daily work and improves work efficiency.

[0026] like Figures 2 to 4 As shown, an iron plate 6 is fixedly connected to the bottom of the slot 5, and a magnet 7 that can contact the iron plate 6 is connected to one end of the insertion rod 4 that is inserted into the slot 5.

[0027] Specifically, by fixing an iron plate 6 to the bottom of the slot 5, and connecting a magnet 7 that can contact the iron plate 6 to one end of the insertion rod 4 inserted into the slot 5, the magnetic attraction between the iron plate 6 and the magnet 7 after the insertion rod 4 is inserted into the slot 5 can increase the connection force between the mounting plate 2 and the roller 3, thus preventing the roller 3 from shaking between the mounting plates 2.

[0028] like Figures 2 to 4 As shown, a groove 8 is provided on the peripheral side of the insertion rod 4. A spring 9 is fixedly connected to the bottom of the groove 8. A sliding rod 10 that can slide in the groove 8 is fixedly connected to the other end of the spring 9. The end of the sliding rod 10 away from the spring 9 is hemispherical.

[0029] Specifically, a groove 8 is provided on the peripheral side of the insertion rod 4, and a slide rod 10 is movably connected to the groove 8 via a spring 9. When the insertion rod 4 is inserted into the slot 5, the slide rod 10 will abut against the inner wall of the slot 5 under the elastic force of the spring 9. This increases the stability of the insertion rod 4 in the slot 5 on the basis of the iron plate 6 and the magnet 7. By setting the end of the slide rod 10 away from the spring 9 to be hemispherical, it is easy to insert the insertion rod 4 into the slot 5.

[0030] like Figure 4 As shown, a limiting ring 11 is connected to the opening of the groove 8 to limit the movement of the slide rod 10. The inner diameter of the limiting ring 11 is smaller than the diameter of the upper hemisphere of the slide rod 10.

[0031] Specifically, by setting a limiting ring 11 with an inner diameter smaller than the diameter of the upper hemisphere of the slide rod 10, only the hemisphere part of the slide rod 10 can pass through, thus not affecting the abutment of the insertion rod 4 against the inner wall of the slot 5 and making it convenient to insert the insertion rod 4 into the slot 5.

[0032] like Figure 2 and Figure 3 As shown, the cross-section of the insertion rod 4 is a polygon, and the corresponding slot 5 is a polygon that matches the insertion rod 4.

[0033] Specifically, by setting the cross-section of the insertion rod 4 to be a polygon and the corresponding slot 5 to be a polygon that matches the insertion rod 4, the shaking of the insertion rod 4 can be avoided, thereby increasing the stability of the connection between the roller 3 and the mounting plate 2.

[0034] like Figure 2 As shown, the insertion rods 4 are evenly distributed in a ring on the mounting plate 2.

[0035] Specifically, by setting the insertion rods 4 to be evenly distributed in a ring on the mounting plate 2, the connection force between the mounting plate 2 and the roll 3 is distributed more evenly, thereby increasing the service life of the mounting plate 2 and the roll 3.

[0036] like Figures 1 to 3 As shown, the mounting plate 2 has a snap-fit ​​groove 12 on its peripheral side.

[0037] Specifically, by setting the latching groove 12, it is easy to pull the mounting plate 2, thereby facilitating the pulling of the insert rod 4 out of the slot 5, and thus facilitating the replacement of the roller 3.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
