Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plate rolling machine, concretely relates to a top supporting device for heavy large-diameter plate rolling machine. BACKGROUND

[0002] As a kind of efficient roll bending forming equipment, plate rolling machine is small in residual straight edge, can realize two-end pre-bending, supports numerical control system high-precision automation production, material utilization rate is high, production efficiency is outstanding and other advantages, and occupies important position in plate forming field. With the rapid development of aerospace, military weapons, automobile manufacturing, locomotive and vehicle and shipbuilding industries, the demand for bending and rolling parts is increasing day by day, and the requirement for bending forming precision is also increasingly strict.

[0003] In actual production process, plate rolling is faced with a series of challenges. In the process of rolling, the rolled cylinder is easily affected by gravity and deformed, which leads to the increase of cylinder roundness deviation, thereby affecting the quality of finished product. In order to solve this problem, the existing plate rolling machine is equipped with an upper material supporting device, which mainly functions to effectively support the plate to prevent it from falling due to its own weight.

[0004] However, the upper material supporting device used in the existing plate rolling machine mostly relies on motor-driven nut screw system, that is, lead screw transmission mode. In this transmission mode, the nut drives the roller device to move up and down through the rotation of the lead screw, thereby supporting the upper end of the cylinder. However, in actual application, this upper material supporting device exposes many deficiencies: first, its transmission efficiency is relatively low, which leads to slow response speed, and cannot meet the demand of efficient production. Secondly, in the application scene requiring long stroke support, that is, in the case of large diameter of the rolled cylinder, the mass of the rolled cylinder is also heavy at this time, in order to ensure that the roller device has sufficient stability and supporting force, not only the length of the screw rod needs to be increased, but also the diameter of the screw rod needs to be increased, which not only significantly increases the demand for installation space, makes the overall size of the equipment become more huge, but also greatly improves the complexity and technical difficulty of processing and manufacturing, thereby leading to high overall cost.

[0005] Therefore, we propose a top supporting device for heavy large-diameter plate rolling machine to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0006] In order to solve the technical problems existing in the prior art, the utility model provides a top supporting device for heavy large-diameter plate rolling machine.

[0007] The technical scheme adopted by the utility model is as follows:

[0008] A kind of top support device for heavy large-diameter plate rolling machine, including stand, material supporting bracket and pull rod, the stand is vertically installed on the frame of plate rolling machine, the material supporting bracket is set on the stand and can slide in vertical direction, the top of the stand is equipped with electric hoist, the output end of the electric hoist is connected with material supporting bracket, pull rod is symmetrically arranged on the both sides of the top of the stand, and the pull rod is connected with foundation.

[0009] In further technical solutions, the material supporting bracket includes a sliding frame and a material supporting frame, both of which are movably sleeved on the stand, and the material supporting frame is above the sliding frame and connected to the sliding frame by a hydraulic cylinder.

[0010] In further technical solutions, positioning pins are arranged on both sides of the sliding frame, and a plurality of positioning grooves are formed on both sides of the stand to cooperate with the positioning pins, and drive cylinders are connected to the outside of the positioning pins and connected to the sliding frame.

[0011] In further technical solutions, guide grooves are formed on both sides of the stand, and guide blocks are arranged on the inner side of the sliding frame to cooperate with the guide grooves.

[0012] In further technical solutions, the inner side of the sliding frame is provided with a roller trolley that fits the surface of the stand.

[0013] In further technical solutions, a material supporting end is arranged on the top surface of the front end of the material supporting frame, and a plurality of material supporting wheels are rotatably connected to the material supporting end.

[0014] In further technical solutions, a wheel stopper is arranged outside the material supporting wheels.

[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present application are:

[0016] 1. The present application uses an electric hoist as the driving structure for lifting the material supporting bracket, which has higher transmission efficiency and faster response speed than the traditional screw transmission method, and can easily meet the demand for high-speed production. The high-strength chain design of the electric hoist also realizes long-stroke lifting and greatly saves space.

[0017] 2. The material support bracket of this utility model consists of a lower sliding frame and an upper material support frame, which are stably connected by a hydraulic cylinder. When used with an electric hoist, it exhibits a high degree of flexibility in adjustment and can easily achieve fine-tuning operations, thereby ensuring that the material support frame and the material are in the best fit, improving the accuracy and efficiency of the rolling process.

[0018] 3.

Detailed Implementation

[0023] 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.

[0024] See Figure 1 and Figure 2 This utility model provides a top support device for a heavy-duty large-diameter plate rolling machine, including a column 1, a material support bracket 2, and a tie rod 3. The column 1 is vertically installed on the plate rolling machine frame. The material support bracket 2 is sleeved on the column 1 and can slide in the vertical direction. An electric hoist 4 is provided at the top of the column 1. The output end of the electric hoist 4 is connected to the material support bracket 2. Tie rods 3 are symmetrically arranged on both sides of the top of the column 1. The tie rods 3 are connected to the foundation.

[0025] The specific working principle of the top support device for this plate rolling machine is as follows:

[0026] First, the column 1 is vertically installed on the plate rolling machine frame, serving as the main support component of the entire top support device, ensuring structural stability and load-bearing capacity. The material support bracket 2 is fitted onto the column 1 and driven by an electric hoist 4, enabling vertical height adjustment to accommodate plate rolling requirements of different thicknesses and sizes. Symmetrical tie rods 3 are installed on both sides of the top of the column 1, connecting it to the foundation to form a stable support system. This design not only enhances the stability of the column 1 and material support bracket 2 under stress, effectively preventing the risk of tilting or collapse, but also further improves the reliability and safety of the entire top support device, providing a solid guarantee for efficient and safe plate rolling operations. Specifically, during the actual plate rolling operation, the operator can adjust the height of the material support bracket 2 using the electric hoist 4 according to the plate thickness and rolling requirements. In this way, the material support bracket 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 the electric hoist 4 is used as the driving structure for lifting the material support bracket 2, compared with the traditional screw drive method, the electric hoist 4 not only has higher transmission efficiency and faster response speed, but can also easily meet the needs of high-speed production. Moreover, the high-strength chain design adopted by the electric hoist 4 enables long-stroke lifting while greatly saving space. This design simplifies the overall structure, effectively avoids the need for processing large-diameter screws, and makes the disassembly and assembly of the equipment more convenient, reducing manufacturing and maintenance costs, and providing strong support for the company's sustainable development and efficient operation.

[0027] In one specific implementation, see Figure 1 The material support bracket 2 includes a sliding frame 201 and a material support frame 202. Both the sliding frame 201 and the material support frame 202 are movably sleeved on the column 1. The material support frame 202 is located above the sliding frame 201 and is connected to the sliding frame 201 through a hydraulic cylinder 5.

[0028] The material support bracket 2 consists of a lower sliding frame 201 and an upper material support frame 202, which are securely connected by a hydraulic cylinder 5. Height adjustment is simple and efficient. First, the electric hoist 4 is used to adjust the entire material support bracket 2 to approximately the required height. Then, using the precise extension and retraction function of the hydraulic cylinder 5, the material support frame 202 is fine-tuned to ensure its height accurately adapts to sheets of different thicknesses and sizes. This adjustment mechanism not only demonstrates high flexibility but also easily achieves fine-tuning operations, ensuring optimal fit between the material support frame 202 and the sheet material, thus improving the precision and efficiency of the rolling process.

[0029] In one specific implementation, see Figure 1 andFigure 2 The sliding frame 201 has a positioning pin 6 through both sides, and the column 1 has multiple positioning grooves 7 that cooperate with the positioning pin 6 on both sides. The outer side of the positioning pin 6 is connected to a driving cylinder 8, which is connected to the sliding frame 201.

[0030] After the entire material support bracket 2 is adjusted to the approximate required height position by the electric hoist 4, the drive cylinders 8 on both sides of the sliding frame 201 push the positioning pin 6 into the positioning groove 7 of the column 1, thereby locking the sliding frame 201 at the current height position. This ensures that the material support bracket 2 is stably locked at a specific height, avoiding displacement caused by shaking, vibration or external interference, thereby enhancing the stability and safety of the entire top support device and providing solid and reliable support for subsequent rolling operations.

[0031] In one specific implementation, see Figure 1 and Figure 2 The column 1 has guide grooves 9 on both sides, and the sliding frame 201 has guide blocks 10 that cooperate with the guide grooves 9 on the inner side.

[0032] The cooperation between the guide block 10 and the guide groove 9 ensures the stability and straightness of the sliding frame 201 when sliding on the column 1, effectively preventing shaking and deviation, and making the sliding frame 201 more stable and reliable when adjusting its height. Similarly, guide blocks 10 can also be set on the inner side of the material support frame 202 to ensure the stability and straightness of the material support frame 202 when sliding on the column 1, which is beneficial to its use.

[0033] In one specific implementation, see Figure 2 The inner side of the sliding frame 201 is provided with a roller trolley 11 that fits against the surface of the column 1.

[0034] By installing a roller trolley 11 on the inner side of the sliding frame 201, the friction between the sliding frame 201 and the column 1 is reduced, thereby effectively improving the smoothness and efficiency of the sliding process of the sliding frame 201, reducing energy loss and component wear, extending the service life of the device, and thus ensuring higher operational stability and long-term operational reliability. Similarly, a roller trolley 11 can also be installed on the inner side of the material support frame 202, thereby reducing the friction between the material support frame 202 and the column 1, effectively improving the smoothness and efficiency of the sliding process of the material support frame 202, which is beneficial to use.

[0035] In one specific implementation, see Figure 1 The material support frame 202 has a material support end 12 on its top surface at the front end, and multiple material support wheels 13 are rotatably connected to the material support end 12.

[0036] The material support roller 13 supports the processed sheet material, and the material support roller 13 makes rolling contact with the sheet material. This not only reduces resistance but also prevents the sheet material from deforming due to contact, thus ensuring the quality of the sheet material forming.

[0037] In one specific implementation, see Figure 1 The material support end 12 is provided with a stop wheel 14 on the outside of the material support wheel 13.

[0038] The setting of the guide roller 14 can effectively constrain the position of the rolled body, thereby preventing the sheet from sliding or shifting laterally on the support roller 13, avoiding the risk of the sheet accidentally sliding out of the support end 12, ensuring the stability and accuracy of the sheet during the rolling process, and playing a key role in accurately controlling the rolling shape and improving product quality.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
