Description

Technical Field

[0001] This invention belongs to the technical field of plate rolling equipment, and relates to plate rolling equipment for processing stainless steel sinks. Background Technology

[0002] Stainless steel sinks are widely used due to their corrosion resistance and ease of cleaning. Square and irregularly shaped sinks commonly found in household kitchens are mostly formed by stamping and stretching using large hydraulic presses, suitable for mass production. However, in commercial, industrial, and customized settings, there are sinks with rotating structures such as cylindrical, semi-cylindrical, and elliptical sinks, including canteen washing sinks, food processing plant troughs, and custom decorative sinks. Traditional stamping processes are costly and prone to defects for these types of sinks; therefore, plate rolling is the preferred manufacturing method due to its lower equipment investment and suitability for thick plates and large-diameter structures.

[0003] Currently, in existing technology, plate rolling equipment applies pressure to stainless steel material by driving an actively rotating extrusion roller. Through rotation, the material is squeezed into a cylindrical shape. The auxiliary extrusion roller located above provides limiting support for the lower extrusion roller. After processing, it is generally necessary to disengage the two extrusion rollers before the processed material can be removed. However, the unloading process in existing technology usually relies on manual labor and cannot be automated. Furthermore, the sides of stainless steel can easily cause injury to workers.

[0004] Patent document CN118455331A discloses a plate rolling device for processing stainless steel water tanks, including a base, a support base, and a top plate. A hydraulic rod is mounted on the top of the base, and a movable frame is fixedly installed at the telescopic end of the hydraulic rod. The movable frame is movably engaged inside the support base. An active extrusion roller is rotatably mounted inside the movable frame via a first rotating shaft. A reduction motor is located on the right side of the movable frame, and the output shaft of the reduction motor is fixedly connected to the first rotating shaft. This device drives the passive extrusion roller and the discharge ring to rotate, propelling the material to the right. Simultaneously, a downward-moving rack pulls down the connecting rope and causes an auxiliary plate to rotate counterclockwise around the axis of the fixed column, releasing the right-side limiting obstruction of the material. This allows the material to be automatically discharged after the movable frame moves down and resets, effectively avoiding the drawbacks of low efficiency and low safety associated with manual labor.

[0005] However, the problem with this device in actual use is that when the center of the material moves outside the passive extrusion roller, the right end of the material falls downward under its own weight, which can easily cause the material to tilt and get stuck on the right end of the passive extrusion roller, resulting in poor material feeding or requiring manual intervention.

[0006] To address the aforementioned problems, this invention proposes a plate rolling equipment for processing stainless steel sinks. Summary of the Invention

[0007] To address the problems existing in the background art, the present invention proposes a plate rolling equipment for processing stainless steel water tanks.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-9 As shown, the technical solution adopted by the present invention is as follows: the plate rolling equipment for processing stainless steel water tanks includes a base 1, a lower extrusion roller 6, an upper extrusion roller and a material guiding assembly.

[0020] like Figure 1 , Figure 3 As shown, a connecting frame 4 is installed on the base 1. Specifically, a hydraulic rod 3 is fixedly installed on the base 1. The hydraulic rod 3 is vertically positioned, with its telescopic end pointing vertically upwards. The connecting frame 4 is fixedly connected to the telescopic end of the hydraulic rod 3. To ensure that the connecting frame 4 is stably positioned on the base 1, stabilizing rods 2 are provided on both sides of the hydraulic rod 3. The lower end of the stabilizing rod 2 is fixedly connected to the base 1, and the upper end of the stabilizing rod 2 is fixedly connected to the connecting frame 4.

[0021] The lower extrusion roller 6 is rotatably mounted on the connecting frame 4. A motor 5 is mounted on the connecting frame 4, and the output shaft of the motor 5 is fixedly connected to one end of the lower extrusion roller 6.

[0022] One end of the upper extrusion roller is rotatably mounted on the base 1 and positioned above the lower extrusion roller 6. Specifically, a fixing block 16 is fixedly mounted on the base 1, and one end of the upper extrusion roller is rotatably connected to the lower extrusion roller 6. An auxiliary plate 13 is fitted to the other end of the upper extrusion roller, and the auxiliary plate 13 is vertically movable to the base 1. A linkage assembly is provided between the auxiliary plate 13 and the connecting frame 4. When the lower extrusion roller 6 moves upward and approaches the upper extrusion roller, forming a suitable roller gap between them, the auxiliary plate 13 abuts against the end of the upper extrusion roller to limit the end of the upper extrusion roller away from the fixing block 16, thus stabilizing the upper extrusion roller. When the connecting frame 4 moves downward and the lower extrusion roller 6 moves away from the upper extrusion roller, the auxiliary plate 13 moves upward and away from the upper extrusion roller to facilitate material unloading.

[0023] The linkage assembly includes a connecting rope 9 and a sliding seat 12. The sliding seat 12 is elastically slidably disposed at the upper end of the base 1. Specifically, as shown... Figure 3 As shown, a mounting plate is fixed to the upper end of the base 1, and a spring 11 is fixedly connected between the mounting plate and the sliding seat 12.

[0024] Two guide grooves 15 are symmetrically formed on the sliding seat 12. Each guide groove 15 includes a first horizontal section, a second horizontal section, and an inclined section. The two ends of the inclined section are connected to the first and second horizontal sections, respectively, and the second horizontal section is higher than the first horizontal section. The second horizontal section is located on the side of the inclined section away from the mounting plate. Both sides of the auxiliary plate 13 are fixedly connected to protrusions 14, which are slidably disposed within the corresponding guide grooves 15.

[0025] A guide wheel 10 is rotatably mounted on the upper end of the base 1. One end of the connecting rope 9 is connected to the sliding seat 12, and the other end of the connecting rope 9 passes around the guide wheel 10 and is connected to the connecting frame 4. The guide wheel 10 guides and reverses the direction of the connecting rope 9, allowing the connecting rope 9 to move smoothly.

[0026] When the connecting frame 4 moves downward, it pulls the sliding seat 12 to slide via the connecting rope 9. The spring 11 deforms elastically, and the auxiliary plate 13 moves upward under the action of the guide groove 15. When the connecting frame 4 moves upward, the sliding seat 12 moves under the action of the spring 11, and the auxiliary plate 13 moves downward.

[0027] The material guide assembly is positioned above the upper extrusion roller. After the steel is rolled into a roll, the material guide assembly causes the roll to automatically detach from the upper extrusion roller, thus automatically completing the unloading process.

[0028] In this embodiment, the material guiding assembly includes a cam 18, a circular block 20, and a movable plate 8. A connecting rod 17 is rotatably mounted inside the upper extrusion roller 7, with one end of the connecting rod 17 fixedly connected to a fixed block 16. The cam 18 is fixedly connected to the end of the connecting rod 17 away from the auxiliary plate 13, and the circular block 20 is fixedly connected to the end of the connecting rod 17 near the auxiliary plate 13. The circular block 20 is rotatably connected to the upper extrusion roller 7. Limiting grooves 21 are provided on the rotating surfaces of both the cam 18 and the circular block 20.

[0029] The upper extrusion roller 7 has multiple through holes distributed along its circumference. A movable plate 8 is slidably disposed within each through hole. Connecting blocks 19 are connected to both ends of the movable plate 8 that extend into the upper extrusion roller 7, and these connecting blocks 19 are slidably disposed within limiting grooves 21 on the same side. Specifically, as shown... Figures 5 to 9 As shown, the movable plate 8 has a connecting hole 23 at one end inside the upper extrusion roller 7, and a waist-shaped groove 22 at the other end. The connecting block 19 includes a sliding column 1901 and a mounting base 1902. The sliding column 1901 is slidably disposed in the limiting groove 21, and the mounting base 1902 is fixed on the sliding column 1901. A connecting column 1903 is mounted on the mounting base 1902. The connecting hole 23 is fitted onto the connecting column 1903 on the circular block 20, and the waist-shaped groove 22 is slidably fitted onto the connecting column 1903 on the cam 18.

[0030] The radius of the profile of cam 18 on the side closest to the lower extrusion roller 6 is equal to the radius of the circular block 20 to ensure the quality of the drum. The distance from the profile of cam 18 on the side furthest from the lower extrusion roller 6 to the axis of the circular block 20 is greater than the radius of the circular block 20. As the upper extrusion roller 7 rotates, it drives the movable plate 8 to move, and the connecting block 19 slides along the limiting groove 21. When the movable plate 8 is on the side of the upper extrusion roller 7 closest to the lower extrusion roller 6, the movable plate 8 is in a horizontal state, parallel to the axis of the upper extrusion roller 7, and flush with the surface of the upper extrusion roller 7. When the movable plate 8 is on the side of the upper extrusion roller 7 furthest from the lower extrusion roller 6, the end of the movable plate 8 closest to cam 18 tilts upward, and the movable plate 8 extends outside the upper extrusion roller 7.

[0031] Working principle: The stainless steel sheet to be processed is fed into the gap between the lower extrusion roller 6 and the upper extrusion roller 7.

[0032] Start the hydraulic rod 3 to push the connecting frame 4 and the lower extrusion roller 6 installed on it to move upward, together with the upper extrusion roller 7 to press the stainless steel plate.

[0033] Simultaneously, as the connecting frame 4 moves upward, the sliding seat 12 moves away from the mounting plate under the action of the spring 11, the protrusion 14 moves from the second horizontal section through the inclined section into the first horizontal section, and the auxiliary plate 13 moves downward. This continues until the auxiliary plate 13 presses against the end of the upper extrusion roller 7, ensuring the stability of the upper extrusion roller 7.

[0034] Start motor 5 to drive the lower extrusion roller 6 to rotate, which in turn drives the stainless steel sheet and the upper extrusion roller 7 to rotate together through friction. The stainless steel sheet undergoes plastic bending as it passes through the roller gap and is rolled into a roll.

[0035] When the upper extrusion roller 7 rotates, it drives the cam 18, the circular block 20, and the movable plate 8 to rotate. When the movable plate 8 rotates to the processing area close to the lower extrusion roller 6, it retracts into the surface of the upper extrusion roller 7 without affecting the winding. When the movable plate 8 rotates to the area above the lower extrusion roller 6, its end tilts upward and extends outward, and the end near the auxiliary plate 13 tilts downward to receive and guide the falling roll out.

[0036] After winding is completed, the hydraulic rod 3 retracts, causing the connecting frame 4 and the lower extrusion roller 6 to move downwards. The distance between the lower extrusion roller 6 and the upper extrusion roller 7 increases. After losing the support of the lower extrusion roller 6, the roll falls onto the movable plate 8 located above the upper extrusion roller 7 under its own gravity.

[0037] When the connecting frame 4 moves downward, the connecting rope 9 pulls the sliding seat 12 to move horizontally against the elastic force of the spring 11. The sliding seat 12 moves the protrusion 14 upward through the guide groove 15, causing the auxiliary plate 13 to slide upward and move away from the end of the upper extrusion roller 7, making room for material feeding. Then, the drum slides down one side of the upper extrusion roller 7 under its own gravity, thus realizing automatic material feeding.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
