Description

Technical Field

[0001] This utility model belongs to the technical field of plate rolling machines, and specifically relates to a top support structure for plate rolling machines. Background Technology

[0002] Plate rolling machines, as a type of high-efficiency roll bending forming equipment, occupy an important position in the field of sheet metal forming due to their advantages such as small residual straight edges, ability to pre-bend at both ends, support for high-precision automated production via CNC systems, high material utilization, and outstanding production efficiency. With the rapid development of industries such as aerospace, military weaponry, automobile manufacturing, locomotives and rolling stock, and shipbuilding, the demand for rolled parts is increasing daily, while the requirements for rolling forming precision are becoming increasingly stringent.

[0003] In actual production, the rolling of sheet metal faces a series of challenges. During the rolling process, the rolled cylinder is easily deformed by gravity, leading to increased deviations in cylinder roundness and affecting the quality of the finished product. To solve this problem, existing plate rolling machines are equipped with a top support device. The main function of this device is to effectively support the sheet metal to prevent it from collapsing under its own weight.

[0004] However, most existing plate rolling machines rely on motor-driven nut and screw systems, i.e., screw transmission. In this transmission method, the nut drives the roller device up and down via the rotation of the screw, thus supporting the upper end of the cylinder. In practical applications, this type of upper support device has revealed several shortcomings: First, its transmission efficiency is relatively low, resulting in slow response speed, which cannot meet the demands of high-efficiency production. Second, in applications requiring longer stroke support, i.e., when the diameter of the rolled cylinder is large and its mass is also heavy, ensuring sufficient stability and support force for the roller device requires not only increasing the length of the screw but also its diameter. This significantly increases the installation space requirement, making the overall equipment larger, and also greatly increases the complexity and technical difficulty of manufacturing, leading to high overall costs.

[0005] Therefore, we propose a top support structure for plate rolling machines to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the technical problems existing in the prior art, this utility model proposes a top support structure for a plate rolling machine.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A top support structure for a plate rolling machine includes a column, a material support frame, and two tie rods. The column is vertically installed on the frame of the plate rolling machine. The material support frame is vertically installed on one side of the column and can slide in the vertical direction. A hydraulic cylinder is provided on the column, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the material support frame. The two tie rods are symmetrically arranged at the top of the other side of the column and are both connected to the foundation.

[0009] In a further technical solution, the column has a guide groove on one side of the material support frame, the end of the material support frame is slidably installed in the guide groove, and the bottom of the hydraulic cylinder is installed on the inner bottom surface of the guide groove.

[0010] In a further technical solution, the material support frame is provided with multiple guide wheels on both sides of its end, which slide in cooperation with the guide groove.

[0011] In a further technical solution, multiple material support wheels are rotatably connected to the top surface of the front end of the material support frame.

[0012] In a further technical solution, the column includes a base plate, a top plate, and two I-beams. The two I-beams are arranged in parallel and their ends are welded to the base plate and the top plate, respectively. The base plate is detachably connected to the plate rolling machine frame by bolts.

[0013] In a further technical solution, the hydraulic cylinder is a three-stage sleeve cylinder.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a hydraulic cylinder as the transmission structure. Compared with the traditional screw transmission method, the hydraulic cylinder has high transmission efficiency and fast response speed, which can meet the needs of high-efficiency production. At the same time, the hydraulic cylinder occupies less space, simplifies the overall structure, makes the processing process simpler and more convenient, reduces manufacturing and maintenance costs, and provides strong support for the sustainable development and efficient operation of enterprises.

[0016] 2. The column of this utility model is a frame structure welded from a base plate, a top plate and two I-beams, which has both structural stability and safety. The assembly process is simple, and the parts used in the manufacturing process can all be derived from recycled waste materials. This not only improves the recycling rate of materials and realizes the green cycle of resources, but also greatly reduces manufacturing costs, demonstrating the dual advantages of environmental protection and economic benefits.

[0017] 3. The hydraulic cylinder of this utility model adopts a three-stage sleeve cylinder, which makes its overall structure more compact and the cylinder length significantly shortened. Compared with the traditional ordinary cylinder, under the same stroke conditions, this three-stage sleeve cylinder design can process cylindrical workpieces with smaller diameters, which not only improves the flexibility of equipment in terms of space utilization, but also improves the accuracy of workpiece processing and increases the types of workpieces that can be processed.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figure 1 and Figure 2 This utility model provides a top support structure for a plate rolling machine, including a column 1, a material support frame 2, and two tie rods 3. The column 1 is vertically installed on the frame of the plate rolling machine. The material support frame 2 is vertically installed on one side of the column 1 and can slide in the vertical direction. A hydraulic cylinder 4 is provided on the column 1. The output end of the hydraulic cylinder 4 is fixedly connected to the bottom of the material support frame 2. The two tie rods 3 are symmetrically arranged at the top of the other side of the column 1 and are both connected to the foundation.

[0024] The specific working principle of the top support structure used in this plate rolling machine is as follows:

[0025] First, the column 1 is vertically installed on the plate rolling machine frame, serving as the main support component of the entire top support structure, ensuring the stability and load-bearing capacity of the structure. The material support frame 2 is vertically installed on one side of the column 1 and driven by a hydraulic cylinder 4, enabling vertical height adjustment to accommodate plate rolling requirements of different thicknesses and sizes. Two tie rods 3 are connected at one end to the top of the column 1 and at the other end to the foundation, forming a stable support system. This design not only enhances the stability of the column 1 and material support frame 2 under stress, effectively preventing the risk of tilting or collapse, but also further improves the reliability and safety of the entire top support structure, providing a solid guarantee for efficient and safe plate rolling operations. Specifically, in the actual operation of plate rolling, the operator can adjust the height of the material support frame 2 by controlling the extension and retraction of the hydraulic cylinder 4 according to the plate thickness and rolling requirements. In this way, the material support frame 2 can effectively support the plate, preventing it from collapsing or deforming due to its own weight, thereby ensuring that the rolled cylinder has good roundness and quality. Because it uses a hydraulic cylinder 4 as the transmission structure, compared with the traditional screw drive method, the hydraulic cylinder 4 has high transmission efficiency and fast response speed, which can meet the needs of high-efficiency production. At the same time, the hydraulic cylinder 4 occupies less space, simplifies the overall structure, makes the processing process simpler and more convenient, reduces manufacturing and maintenance costs, and provides strong support for the company's sustainable development and efficient operation.

[0026] In one specific implementation, see Figure 1 The column 1 has a guide groove 5 on one side of the material support frame 2. The end of the material support frame 2 is slidably installed in the guide groove 5. The bottom of the hydraulic cylinder 4 is installed on the inner bottom surface of the guide groove 5.

[0027] The guide groove 5 provides a sliding track for the material support frame 2, ensuring smooth and stable vertical movement of the material support frame 2. This effectively prevents swaying or deviation that may occur during lifting and lowering, thus guaranteeing the accuracy of plate rolling and the quality of the finished product. Simultaneously, this embedded design makes the entire top support structure more compact, reducing space occupation and resulting in a more scientific and rational overall layout, laying a solid foundation for the efficient and stable production of the plate rolling machine.

[0028] In one specific implementation, see Figure 1 and Figure 2 The material support frame 2 has multiple guide wheels 6 on both sides of its end that slide in cooperation with the guide groove 5.

[0029] The material support frame 2 slides on the guide groove 5 via the guide wheel 6, which not only makes the lifting process of the material support frame 2 more stable, but also reduces the resistance and wear caused by direct friction, thereby extending the service life of the material support frame 2 and the guide groove 5.

[0030] In one specific implementation, see Figure 1 and Figure 2 Multiple material support wheels 7 are rotatably connected to the top surface of the front end of the material support frame 2.

[0031] The material support roller 7 supports the processed sheet metal, and the rolling contact between the material support roller 7 and the sheet metal not only reduces resistance but also prevents the sheet metal from deforming due to contact, thus ensuring the quality of sheet metal forming.

[0032] In one specific implementation, see Figure 1 The column 1 includes a base plate 101, a top plate 102 and two I-beams 103. The two I-beams 103 are arranged in parallel and their ends are welded to the base plate 101 and the top plate 102 respectively. The base plate 101 is detachably connected to the plate rolling machine frame by bolts.

[0033] Column 1, as the main supporting component of the entire top support structure, is a frame structure welded from a base plate 101, a top plate 102, and two I-beams 103, possessing both structural stability and safety. Furthermore, the assembly process is simple, and all parts used in the manufacturing process can be derived from recycled waste materials, which not only improves the recycling rate of materials and achieves green resource recycling, but also greatly reduces manufacturing costs, demonstrating the dual advantages of environmental protection and economic benefits.

[0034] In one specific embodiment, the hydraulic cylinder 4 is a three-stage sleeve cylinder.

[0035] Hydraulic cylinder 4 employs a three-stage sleeve design, resulting in a more compact overall structure and a significantly shorter cylinder length. Compared to traditional hydraulic cylinders, under the same stroke conditions, this three-stage sleeve design allows hydraulic cylinder 4 to process cylindrical workpieces with smaller diameters. This design not only enhances the equipment's flexibility in space utilization but also improves workpiece processing accuracy and increases the variety of workpieces that can be processed.
