Description

Technical Field

[0001] This utility model relates to the field of steel plate production technology, specifically to a cold rolling device for steel plate production. Background Technology

[0002] Cold rolling equipment for steel plate production is a key piece of equipment for cold rolling hot-rolled steel plates. It is used to further reduce the thickness of the steel plate and improve surface quality and dimensional accuracy. Its core consists of a rolling mill (mostly four-roll or six-roll), an uncoiler, a coiler, a leveler, and a control system. During operation, the hot-rolled steel plate is unrolled by the uncoiler and enters the rolling mill, where it is rolled by high-strength rolls to achieve plastic deformation at room temperature. The thickness can be reduced to less than 0.1 mm. Subsequently, the plate is stress-relieved and its shape is improved by the leveler, and finally, it is coiled up by the coiler. This equipment is widely used in the production of high-precision sheet metal such as automotive steel plates and appliance steel plates, and can significantly improve the mechanical properties and surface finish of the steel plate.

[0003] Chinese Utility Model Patent Publication No. CN213559128U discloses a cold rolling mill for steel plates. The specification of this cold rolling mill discloses that by adopting a two-stage cold rolling roll, the position of the first cold rolling roll mechanism can be adjusted by a hydraulic cylinder, allowing steel plates of different thicknesses to be tightly squeezed and bonded together, facilitating cold rolling. By setting a notch, it is easy for the cold rolling roll to be inserted and installed from the outside, facilitating assembly and replacement. However, this cold rolling mill for steel plates does not have a design for a correction component, and the steel plate is prone to shifting during the cold rolling process. In addition, it does not have a top plate mounting structure, making it inconvenient to quickly disassemble and assemble during use or assembly, resulting in poor practicality and hindering its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cold rolling device for steel plate production. It can effectively solve the problems of existing technology, which does not have a correction component, the steel plate is prone to deviation during the cold rolling process, and the lack of a top plate installation structure makes it inconvenient to quickly disassemble and assemble during use or assembly, resulting in poor practicality and difficulty in promotion and use.

[0005] The technical solution adopted by this utility model is: a cold rolling device for steel plate production, including a base plate, a mounting frame and a top plate. A plug is fixedly installed on the side of the top plate near the mounting frame. A threaded hole is opened on the side of the top plate away from the mounting frame.

A bolt adapted to the threaded hole and the threaded hole are threadedly connected to the side of the top plate away from the mounting frame. An adjustment component is provided on the side of the top plate away from the mounting frame. A first roller group is provided on the end of the mounting frame away from the top plate. A correction component is fixedly installed at the front end of the mounting frame.

[0006] Preferably, the insert and the slot are plugged in, and the bolt extends through the first threaded hole to the inside of the second threaded hole, wherein the first threaded hole and the second threaded hole have the same diameter.

[0007] Using the above technical solution, the staff inserts the plug into the inside of the slot, and then extends the bolt through the threaded hole one to the inside of the threaded hole two, which can realize the quick fixation between the top plate and the mounting bracket, and facilitate quick disassembly and assembly during use or assembly.

[0008] Preferably, the adjustment assembly includes a motor, a synchronous pulley, a synchronous belt, a synchronous pulley 2, a lead screw, a second roller group, a slider, and a slide groove.

[0009] With the above technical solution, the staff starts motor one, and the output shaft of motor one rotates, which drives screw one to rotate through the cooperation of synchronous pulley one, synchronous belt and synchronous pulley two.

[0010] Preferably, two identical synchronization belts are provided, and the two synchronization belts are symmetrically distributed about the center line of the top plate.

[0011] The above technical solution, through the design of two synchronous belts, ensures that the forces at both ends of the second roller group are the same, making the second roller group more stable during the rising or falling process.

[0012] Preferably, the correction assembly includes a second motor, a second lead screw, a moving block, a slide rod, a baffle, a positioning groove, a guide block, a first through hole, a positioning block, a guide groove, a second through hole, a screw, and a nut.

[0013] With the above technical solution, the staff starts motor two, the output shaft of motor two rotates and drives screw two to rotate, screw two rotates and drives moving block to move on slide bar, thereby driving baffle to move, which is convenient for limiting steel plates of different widths, making it less likely to deviate during cold rolling, and has high practicality.

[0014] Preferably, the positioning block and the positioning groove are plug-in installed, and the guide block and the guide groove are plug-in installed.

[0015] Using the above technical solution, workers insert the positioning block into the positioning groove and the guide block into the guide groove, which enables the rapid positioning of the baffle.

[0016] Preferably, the screw passes through through hole one and through hole two, the diameters of through hole one and through hole two are the same, and the nut abuts against the moving block.

[0017] With the above technical solution, after the baffle is quickly positioned, the workers insert the screw through the first and second through holes, and then connect the nut to the screw thread, so that the nut abuts against the moving block, which can quickly fix the baffle. After long-term use, it is convenient to repair or replace it.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figure 1-5 As shown, the present invention provides a cold rolling device for steel plate production, including a base plate 1, a mounting frame 2 and a top plate 3. A plug block 4 is fixedly installed on the side of the top plate 3 near the mounting frame 2. A threaded hole 5 is opened on the side of the top plate 3 away from the mounting frame 2. A slot 6 and a threaded hole 7 are opened on the end of the mounting frame 2 near the top plate 3. A bolt 8 that matches the threaded hole 5 and the threaded hole 7 is threadedly connected to the side of the top plate 3 away from the mounting frame 2. An adjustment component 9 is provided on the side of the top plate 3 away from the mounting frame 2. A first roller group 10 is provided on the end of the mounting frame 2 away from the top plate 3. A correction component 11 is fixedly installed at the front end of the mounting frame 2.

[0024] Specifically, the insert 4 and the slot 6 are plug-in mounted, and the bolt 8 extends through the threaded hole 5 to the inside of the threaded hole 7. The threaded holes 5 and 7 have the same diameter. The advantage is that the operator can quickly fix the top plate 3 and the mounting bracket 2 by inserting the insert 4 into the slot 6 and then extending the bolt 8 through the threaded hole 5 to the inside of the threaded hole 7. This facilitates quick assembly and disassembly during use or assembly.

[0025] Specifically, the adjustment assembly 9 includes a motor 901, a synchronous pulley 902, a synchronous belt 903, a synchronous pulley 904, a lead screw 905, a second roller group 906, a slider 907, and a groove 908. The output end of the motor 901 is fixedly mounted with the synchronous pulley 902. The outer wall of the synchronous pulley 902 is meshed with the synchronous belt 903. The side of the top plate 3 away from the mounting frame 2 is rotatably mounted with the synchronous pulley 904. The end of the synchronous pulley 904 near the mounting frame 2 is fixedly mounted with the lead screw 905. The outer wall of the lead screw 905 is threadedly connected to the second roller group 906. The outer wall of the second roller group 906 is fixedly mounted with the slider 907. The inner wall of the mounting frame 2 is provided with a groove 908. The synchronous pulley 904 and the synchronous belt 903 are meshed together, and the slider 907 and the groove 908 are slidably connected. The advantage is that when the operator starts motor 901, the output shaft of motor 901 rotates, which drives screw 905 to rotate through the cooperation of synchronous pulley 902, synchronous belt 903 and synchronous pulley 904. The rotation of screw 905 drives the second roller group 906 to move, which makes it easy to adjust the distance between the second roller group 906 and the first roller group 10, thus facilitating the cold rolling of steel plates of different thicknesses and making it highly adaptable.

[0026] Specifically, two identical synchronous belts 903 are provided, and the two synchronous belts 903 are symmetrically distributed about the center line of the top plate 3. The advantage is that the design of two synchronous belts 903 ensures that the forces at both ends of the second roller group 906 are the same, making the second roller group 906 more stable during the rising or falling process. Example 2

[0027] like Figure 2-5As shown, as an improvement on the previous embodiment, to prevent the steel plate from shifting during cold rolling, the correction assembly 11 specifically includes a second motor 1101, a second lead screw 1102, a moving block 1103, a slide bar 1104, a baffle 1105, a positioning groove 1106, a guide block 1107, a first through hole 1108, a positioning block 1109, a guide groove 1110, a second through hole 1111, a screw 1112, and a nut 1113. The output end of the second motor 1101 is fixedly mounted with the second lead screw 1102, and the outer wall of the second lead screw 1102 is threadedly connected to the moving block 1103. The front end of the mounting bracket 2 is fixedly mounted with the slide bar 1104, and the moving block 1103 is located away from the second lead screw 1102. One end of 2 is provided with a baffle 1105. The end of the moving block 1103 near the baffle 1105 is provided with a positioning groove 1106 and a through hole 1108. A guide block 1107 is fixedly installed on the inner wall of the through hole 1108. A positioning block 1109 is fixedly installed on the end of the baffle 1105 near the moving block 1103. A guide groove 1110 and a through hole 2 1111 are provided on the end of the baffle 1103 near the moving block 1103. A screw 1112 is inserted and installed on the end of the moving block 1103 near the baffle 1105. A nut 1113 is threadedly connected to the outer wall of the screw 1112. The screw 2 1102 is a two-way screw. The moving block 1103 and the slide rod 1104 are slidably connected. The advantage is that when the operator starts the motor 1101, the output shaft of the motor 1101 rotates, which drives the lead screw 1102 to rotate. The rotation of the lead screw 1102 drives the moving block 1103 to move on the slide bar 1104, thereby driving the baffle 1105 to move. This makes it easy to limit the movement of steel plates of different widths, making it less likely to deviate during the cold rolling process, and it is highly practical.

[0028] Specifically, the positioning block 1109 and the positioning groove 1106 are installed by insertion, and the guide block 1107 and the guide groove 1110 are installed by insertion. The advantage is that when the operator inserts the positioning block 1109 into the positioning groove 1106 and the guide block 1107 into the guide groove 1110, the baffle 1105 can be quickly positioned.

[0029] Specifically, the screw 1112 passes through through hole one 1108 and through hole two 1111, with the same diameter. The nut 1113 abuts against the moving block 1103. The advantage is that after quickly positioning the baffle 1105, the operator can pass the screw 1112 through through hole one 1108 and through hole two 1111, and then thread the nut 1113 onto the screw 1112, causing the nut 1113 to abut against the moving block 1103. This allows for quick fixing of the baffle 1105 and facilitates maintenance or replacement after prolonged use.

[0030] Working principle: During installation, the operator inserts the insert block 4 into the slot 6, and then inserts the bolt 8 through the threaded hole 5 to the threaded hole 7, which quickly fixes the top plate 3 to the mounting bracket 2, facilitating quick assembly and disassembly during use or assembly. The operator then inserts the positioning block 1109 into the positioning groove 1106 and the guide block 1107 into the guide groove 1110, quickly positioning the baffle 1105. After quickly positioning the baffle 1105, the operator inserts the screw 1112 through the through hole 1108 and the through hole 1111, and then threads the nut 1113 onto the screw 1112, causing the nut 1113 to abut against the moving block 1103, quickly fixing the baffle 1105. This facilitates maintenance or replacement after prolonged use. During use, the operator starts the motor 901. The output shaft of 901 rotates, driving the lead screw 905 to rotate via the cooperation of synchronous pulley 902, synchronous belt 903, and synchronous pulley 904. The rotation of lead screw 905 drives the second roller group 906 to move, thus facilitating the adjustment of the distance between the second roller group 906 and the first roller group 10. This allows for the cold rolling of steel plates of different thicknesses, resulting in high adaptability. The design of two synchronous belts 903 ensures that the forces at both ends of the second roller group 906 are equal, making the second roller group 906 more stable during ascent or descent. Simultaneously, the operator starts motor 1101, and the output shaft of motor 1101 rotates, driving the lead screw 1102 to rotate. The rotation of lead screw 1102 drives the moving block 1103 to move on the slide bar 1104, thereby moving the baffle 1105. This facilitates the limiting of steel plates of different widths, making it less prone to deviation during cold rolling, and thus has high practicality.
