Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical processing technology, specifically to an automatic alignment device for blanking rectangular steel plates. Background Technology
[0002] In elevator manufacturing, rectangular steel plates, as the core structural material, require multiple processing steps such as cutting and punching. Currently, the processed rectangular steel plates are typically unloaded onto a placement rack via a conveyor belt, and then manually aligned by workers for forklift transport to subsequent bending and welding stations. However, due to the large weight and volume of rectangular steel plates, manual alignment is not only inefficient but also faces the following problems:
[0003] High labor intensity: Workers need to repeatedly adjust the position of rectangular steel plates, which consumes a lot of physical strength, easily leads to fatigue, and affects production efficiency.
[0004] Significant safety hazards: The rectangular steel plates have sharp edges and are prone to sliding or tipping over during handling, which may cause workplace injuries such as pinching or crushing.
[0005] Insufficient alignment accuracy: Manual operation makes it difficult to ensure the neatness of the rectangular steel plates stacked, which may affect the positioning and processing quality of subsequent processes.
[0006] In existing technologies, placement racks are mostly simple structures, lacking automated alignment or positioning aids, leading to bottlenecks in the production process. Therefore, there is an urgent need for an efficient and safe rectangular steel plate alignment solution to reduce reliance on manual labor, improve production efficiency, and reduce safety hazards. Utility Model Content
[0007] To address the aforementioned technical deficiencies, this invention provides an automatic alignment device for rectangular steel plate blanking, which can automatically align rectangular steel plates during blanking.
[0008] This utility model discloses an automatic alignment device for blanking rectangular steel plates, including a base, which is a cuboid. A first column is vertically fixed on the upper side of one corner of the base. The upper end face of the first column is set in a hemispherical concave shape. Mounting seats are fixed on the upper sides of the other three corners of the base. The mounting seats include two opposing first plates and a second plate horizontally fixed on the upper ends of the two first plates. The second plate has a through hole. A hydraulic cylinder is vertically mounted on the lower side of the second plate, with the hydraulic rod passing through the through hole in the second plate. The upper end of the hydraulic rod is vertically fixed to the second column, whose upper end face is set in a hemispherical concave shape. The hemispherical concave shape at the upper end of the first column and the hemispherical concave shape at the upper end of the second column... Each concave section contains a sphere. The diameter of the sphere in the hemispherical concave section at the upper end of column one is equal to the diameter of the hemispherical concave section at that location. The diameter of the sphere in the hemispherical concave section at the upper end of column two is smaller than the diameter of the hemispherical concave section at that location. A connecting rod is vertically mounted on the upper end of each sphere. A placement plate is mounted on the upper side of the connecting rod. The placement plate is a cuboid. The upper ends of the four connecting rods are fixedly connected to the four corners of the placement plate. A retaining edge is fixedly mounted on the two sides of the upper surface of the placement plate near column one. The retaining edge is perpendicular to the upper surface of the placement plate. The system also includes a control system for extending, retracting, and holding the hydraulic rod on the hydraulic cylinder. The control system for extending, retracting, and holding the hydraulic rod on the hydraulic cylinder is a mature existing technology and will not be described in detail.
[0009] In use, the corner of the placement plate closest to column one is at its lowest point. The control system extends the hydraulic rod diagonally opposite column one to its highest point and holds it there, ensuring the corner of the placement plate at that point is at its highest. Simultaneously, the control system extends the remaining two hydraulic rods to the same height to support the placement plate and holds it there as well. When the rectangular steel plate falls onto the placement plate, it should be noted that the four sides of the rectangular steel plate should be aligned as parallel as possible with the four sides of the placement plate. Since the placement plate is not horizontal, the rectangular steel plate will slide downwards. Eventually, both sides of the rectangular steel plate will press against the retaining edge. After multiple rectangular steel plates are stacked, they are aligned because both sides of the rectangular steel plates are pressing against the retaining edge. Finally, the control system retracts the hydraulic rods to make the placement plate horizontal. Then, the placement plate is transported to the next process by forklift and placed on a horizontal rack for use in subsequent processes.
[0010] To make it easier to place the placement board, the distance between the bottom of the four spheres and the bottom surface of the placement board is equal, so that when it is placed directly on the ground, the placement board is also horizontal and no additional shelf is needed.
[0011] The present invention provides an automatic alignment device for rectangular steel plates, which has the following advantages: by controlling the height of the three corners of the placement plate with a hydraulic cylinder, the placement plate is tilted and the steel plate slides to the two side guards under the action of gravity to achieve alignment. The hydraulic system and the guards work together to achieve rapid alignment of multiple steel plates, improving stacking efficiency. The placement plate can be leveled by a hydraulic rod to facilitate forklift transportation, and the spherical and hemispherical concave structure ensures that the placement plate moves smoothly.

[0016] 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.
[0017] Example 1:
[0018] like Figures 1 to 4As shown, this utility model discloses an automatic alignment device for rectangular steel plate blanking, including a base 1, which is a cuboid. A first column 2 is vertically fixed on the upper side of one corner of the base 1. The upper end face of the first column 2 is set in a hemispherical concave shape. Mounting seats are fixed on the upper sides of the other three corners of the base 1. The mounting seats include two opposing first plates 10 and a second plate 9 horizontally fixed on the upper end of the two first plates 10. The second plate 9 has a through hole. A hydraulic cylinder 11 is vertically mounted on the lower side of the second plate 9, with the hydraulic rod 8 of the hydraulic cylinder 11 passing through the through hole in the second plate 9. A second column 7 is vertically fixed on the upper end of the hydraulic rod 8. The upper end face of the second column 7 is set in a hemispherical concave shape. The hemispherical concave shape at the upper end of the first column 2 and the hemispherical shape at the upper end of the second column 7 are combined. Each concave section contains a sphere 3. The diameter of the sphere 3 in the hemispherical concave section at the upper end of column 1 2 is equal to the diameter of the hemispherical concave section at that location. The diameter of the sphere 3 in the hemispherical concave section at the upper end of column 2 7 is smaller than the diameter of the hemispherical concave section at that location. A connecting rod 4 is vertically mounted on the upper end of each sphere 3. A placement plate 6 is mounted on the upper side of the connecting rod 4. The placement plate 6 is a cuboid. The upper ends of the four connecting rods 4 are fixedly connected to the four corners of the placement plate 6. A retaining edge 5 is fixedly mounted on the two sides of the upper surface of the placement plate 6 near column 1 2. The retaining edge 5 is perpendicular to the upper surface of the placement plate 6. The system also includes a control system for extending, retracting, and holding the hydraulic rod 8 on the hydraulic cylinder 11. The control system for extending, retracting, and holding the hydraulic rod 8 on the hydraulic cylinder 11 is a mature existing technology and will not be described in detail.
[0019] In use, the corner of the placement plate 6 closest to column 2 is at its lowest point. The control system controls the hydraulic rod 8 diagonally opposite column 2 to extend to its highest point and hold it there, ensuring that the corner of the placement plate 6 at that point is at its highest. At the same time, the control system controls the remaining two hydraulic rods 8 to extend to the same height to support the other two corners of the placement plate 6 and hold them there. When the rectangular steel plate falls onto the placement plate 6, the four sides of the rectangular steel plate are as parallel as possible to the four sides of the placement plate. Since the placement plate 6 is not horizontal, the rectangular steel plate will slide downwards. Finally, the two sides of the rectangular steel plate press against the retaining edge 5. After multiple rectangular steel plates are stacked, the rectangular steel plates are aligned because both sides of the rectangular steel plates are pressing against the retaining edge 5. Finally, the control system controls the hydraulic rods 8 to retract, making the placement plate 6 horizontal. Then, the placement plate 6 is transported to the next process by a forklift and placed on a horizontal rack for use in subsequent processes.
[0020] To make it easier to place the placement board 6, the distance between the bottom edge of the four spheres 3 and the bottom surface of the placement board 6 is equal, so that when it is placed directly on the ground, the placement board 6 is also horizontal and no additional shelf is needed.
