Description

Technical Field

[0001] This utility model relates to the field of rolling machine technology, and in particular to a thick plate rolling machine. Background Technology

[0002] A rolling machine is a type of equipment commonly used in the metal processing industry. It is mainly used to roll metal sheets, strips, and other materials into cylindrical or other shapes.

[0003] Chinese utility model patent with publication number CN217700814U discloses a micro-adjustment rolling machine. This rolling machine can adjust the hydraulic pressure according to the thickness of the steel plate, control the hydraulic cylinder to adjust the extension of the hydraulic rod, thereby adjusting the rolling pressure of the upper pressure roller. By controlling the extension of the hydraulic rod through the hydraulic cylinder, the sliders at both ends of the upper pressure roller can also be controlled to slide in the through groove, thereby adjusting the distance between the upper pressure roller and the lower pressure roller for rolling steel plates of different thicknesses.

[0004] While the aforementioned rolling machine can adapt to rolling steel plates of different thicknesses by adjusting the height of the upper pressure roller, for thicker plates, to reduce the rolling difficulty, it is necessary to first increase the distance between the pressure rollers to increase the rolling radius and pre-roll the steel plate to give it a certain curvature, and then decrease the distance between the pressure rollers to reduce the rolling radius and roll the pre-rolled steel plate. The aforementioned rolling machine only allows height adjustment of the upper pressure roller; the other two lower pressure rollers cannot be moved. Therefore, it cannot meet the process requirements of pre-rolling and then rolling thick plates.

[0005] Therefore, this utility model proposes a thick plate rolling machine to solve the above problems. Utility Model Content

An upper pressure roller is disposed above two lower pressure rollers and is driven to rotate by a second drive member. The upper pressure roller is movably mounted on a fixed base via a guide mechanism and is driven to move up and down by a third drive member.

[0008] Furthermore, the guiding mechanism includes a first slider and a second slider, which are rotatably mounted on both ends of the upper pressure roller, a second driving member is fixedly mounted on the second slider and drivenly connected to the upper pressure roller, and two third driving members are respectively disposed below the first slider and the second slider, and the third driving members are drivenly connected to the corresponding first slider or second slider. The fixed base has a first column, and the top of the first column has a U-shaped groove for accommodating the first slider and allowing the first slider to move and extend. The first slider is movably disposed in the U-shaped groove. There are two first guide rails on the side walls of the U-shaped groove. The side walls of the first slider in the radial direction have first track grooves that match the first guide rails. The first guide rails are slidably disposed in the first track grooves on the same side. The fixed base has a second column, and a through groove is opened in the middle of the second column to accommodate the second slider and allow the second slider to move. The second slider is movably disposed in the through groove. A clamping plate assembly is provided on each side of the second slider in the radial direction. Each clamping plate assembly has two clamping plates, which are respectively installed on both sides of the second slider in the axial direction. A guide groove for accommodating the second column is formed between the two clamping plates, and the second column is slidably disposed in the guide groove.

[0009] Furthermore, a first wear-resistant plate is provided on each side of the first guide groove of the first slider, and the first wear-resistant plate is detachably connected to the first slider.

[0010] Furthermore, a second wear-resistant plate is provided between the clamping plate and the second column, and the second wear-resistant plate is detachably connected to the clamping plate.

[0011] Furthermore, the clamping plate has an L-shaped structure, one side of the clamping plate is fixedly connected to the second slider, the second wear-resistant plate is connected to the side of the clamping plate away from the second slider, the second wear-resistant plate and the clamping plate cooperate to form a first limiting groove, and the side wall of the second column has a first protrusion that matches the first limiting groove, the first protrusion being movably disposed in the first limiting groove.

[0012] Furthermore, the first column is provided with an electric push rod for auxiliary positioning. The top end of the electric push rod is hinged to the first slider, and the bottom end of the electric push rod is connected to the first column through a lifting bracket. The bottom end of the electric push rod is hinged to the lifting bracket, and the lifting bracket is movably installed on the first column. The bottom of the first column has a support platform for the lifting bracket.

[0013] Furthermore, a second protrusion is vertically provided on both sides of the U-shaped groove of the first column, and a second limiting groove matching each second protrusion is opened on the lifting bracket.

[0018] This utility model designs the clamping plate as an L-shaped structure, which facilitates connection with the second slider and forms the first limiting groove with the second wear-resistant plate, thereby improving the stability of precision guidance and positioning.

[0019] In this invention, the electric push rod rises and falls synchronously with the first slider during its lifting process, and drives the lifting bracket to move synchronously. When the height of the first slider is adjusted to the correct position, the telescopic rod of the electric push rod moves, causing the lifting bracket to descend to the lifting bracket receiving platform and apply pressure to the first slider, pressing the first slider tightly onto the first guide rail and the clamping plate tightly onto the second column, thereby eliminating the influence of gaps, improving the stability of the upper pressure roller, and preventing the upper pressure roller from shaking.

[0020] This invention uses the cooperation between the second protrusion and the second limiting groove to guide the lifting bracket as it moves with the first slider, thereby improving the accuracy of guidance and the stability of movement. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Example This embodiment provides a thick plate rolling machine, such as Figure 1 As shown, it includes a fixed base 1, two parallel lower pressure rollers 2 and an upper pressure roller 3.

[0028] Two downward pressure rollers 2 are movably mounted on a fixed base 1 and are driven by a first driving member 4 to move closer to or further apart from each other. A third slider 5 is rotatably mounted at each end of each downward pressure roller 2. A second guide rail, corresponding to each third slider 5, is mounted on the fixed base 1. A second track groove matching the second guide rail is opened on the bottom surface of each third slider 5, and the second guide rail is slidably positioned within the first track groove corresponding to the third slider 5. Each third slider 5 corresponds to a first driving member 4, which is a hydraulic cylinder. The first driving member 4 is mounted on the fixed base 1, and its piston rod is connected to the corresponding third slider 5, pushing the third slider 5 to move along the second guide rail.

[0029] The upper pressure roller 3 is positioned above the two lower pressure rollers 2 and is driven to rotate by the second drive member 6. The upper pressure roller 3 is movably mounted on the fixed base 1 via a guide mechanism and is driven to move up and down by the third drive member 7. In this embodiment, the second drive member 6 is a rotary motor, and the third drive member 7 is a hydraulic cylinder.

[0030] In this embodiment, the guiding mechanism includes a first slider 8 and a second slider 9. The first slider 8 and the second slider 9 are rotatably mounted at both ends of the upper pressure roller 3 via bearings. The second driving member 6 is fixedly mounted on the second slider 9 on the side away from the upper pressure roller and is connected to the upper pressure roller 3 in a driving connection. There are two third driving members 7, which are respectively disposed below the first slider 8 and the second slider 9. Each third driving member 7 is connected to the corresponding first slider 8 or second slider 9 in a driving connection.

[0031] The fixed base 1 has a first column 101 and a second column 102, which are respectively disposed on both sides of the lower pressure roller 2 in the axial direction. The top of the first column 101 has a U-shaped groove for accommodating and allowing the first slider 8 to move and extend. The first slider 8 is movably disposed in the U-shaped groove. Two first guide rails are provided on the side walls of the U-shaped groove. First track grooves 801 matching the first guide rails are provided on the side walls of the first slider 8 in the radial direction. The first guide rails are slidably disposed in the first track grooves 801 on the same side. Figure 2As shown, each side of the first guide groove 801 of the first slider 8 is provided with a first wear-resistant plate 802 to evenly distribute the frictional force during the movement of the first slider, avoid jamming or shaking caused by uneven wear on one side, and ensure that the first slider 8 slides smoothly along the predetermined trajectory. The first wear-resistant plate 802 is detachably connected to the first slider 8 by a first screw, which facilitates the removal and replacement of the first wear-resistant plate 802.

[0032] The second column 102 has a through groove in its middle to accommodate and allow the second slider 9 to move. The second slider 9 is movably disposed within the through groove. A clamping plate assembly is provided on each of the radial sides of the second slider 9. Each clamping plate assembly has two clamping plates 901, which are respectively installed on both sides of the second slider 9 in the axial direction. A guide groove for accommodating the second column 102 is formed between the two clamping plates 901, allowing the second column 102 to slide relative to it within the guide groove. In this embodiment, as... Figure 3 As shown, a second wear-resistant plate 902 is provided between each clamping plate 901 and the second column 102. The second wear-resistant plate 902 is detachably connected to the clamping plate 901 by a second screw, thereby improving the wear resistance of the clamping plate, reducing the maintenance frequency, and lowering maintenance costs. The clamping plate 901 has an L-shaped structure. One side of the clamping plate 901 is fixedly connected to the second slider 9. The second wear-resistant plate 902 is connected to the side of the clamping plate 901 away from the second slider 9. The second wear-resistant plate 902 and the clamping plate 901 cooperate to form a first limiting groove. The side wall of the second column 102 has a first protrusion 1021 that matches the first limiting groove. The first protrusion 1021 is relatively movable and set in the first limiting groove, thereby improving the accuracy guidance and positioning stability of the second slider 9.

[0033] In this embodiment, the first column 8 is equipped with an electric push rod 10 for auxiliary positioning. The electric push rod 10 has a self-locking function. The top end of the electric push rod 10 is hinged to the first slider 8, and the bottom end of the electric push rod 10 is connected to the first column 101 through a lifting bracket 11. The bottom end of the electric push rod 10 is hinged to the lifting bracket 11, and the lifting bracket 11 is movably mounted on the first column 101. To improve the accuracy guidance and movement stability of the lifting bracket 11, such as... Figure 4 As shown, a second protrusion 1011 is vertically provided on both sides of the U-shaped groove of the first column 101. The lifting bracket 11 has a second limiting groove that matches each of the second protrusions 1011. The second protrusions 1011 are movably arranged in the second limiting groove. The bottom of the first column 101 has a lifting bracket receiving platform 12, which is located at the bottom end of the second protrusions 1011.

[0034] Working principle: The two lower pressure rollers 2 are driven to move by the first driving component 4, thereby adjusting the distance between them. The upper pressure roller 3 is driven to move up and down by the third driving component 7, adjusting the distance between the upper pressure roller 3 and the lower pressure roller 2, thereby realizing the adjustment of the rolling radius.

[0035] When the upper pressure roller 3 is pushed upward by the third drive member 7, the first slider 8 drives the lifting bracket 11 to move upward synchronously along the first protrusion 1011 via the self-locking electric push rod 10. After the upper pressure roller 3 rises to the specified height, the telescopic rod of the electric push rod 10 extends outward, and the rod cylinder of the electric push rod 10 pushes the lifting bracket 11 down. After it falls onto the lifting bracket receiving platform 12, the telescopic rod of the electric push rod 10 continues to apply pressure to the first slider 8, pressing the first slider 8 tightly onto the first guide rail, and pressing the second wear-resistant plate 902 of the clamping plate 901 tightly onto the second column 102, thereby eliminating the effect of gaps, keeping the upper pressure roller 3 stable, and preventing the upper pressure roller 3 from shaking.

[0036] When the upper pressure roller 3 needs to be lowered, the telescopic rod of the electric push rod 10 needs to be retracted inward in advance. The rod of the electric push rod 10 pulls the lifting bracket 11 upward, so that the lifting bracket 11 is away from the lifting bracket receiving platform 12. After leaving enough space for lowering, the upper pressure roller 3 is lowered to avoid damaging the electric push rod 10.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
