Description

Technical Field

[0001] The utility model belongs to the technical field of flanging equipment, and particularly relates to a flange flanging device. Background Art

[0002] The working principle of a flange flanging machine generally is to use a set of molds or rollers to extrude the edge of a cylinder body, making it deform to form an outward or inward flange. This flange is the flange edge. The flange flanging technology is a process of forming a flange structure at the edge of a metal pipe fitting or container. It is mainly used for the connection of pipelines and containers, especially in those occasions where frequent disassembly or inspection is required.

[0003] In a traditional flange flanging device, during the flanging process of a workpiece, due to the instability of the fixing component, the workpiece gets out of the control of the fixing component under the action of high-speed rotation and strong flanging force, resulting in the workpiece being ejected at high speed, posing a direct life safety threat to the operator, and further causing delays in the production plan and economic losses. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flange flanging device, aiming to solve the problem in the prior art that in a traditional flange flanging device, the workpiece is not stably fixed during the flanging process, and the workpiece gets out of the control of the fixing component under the action of high-speed rotation or strong flanging force, resulting in the workpiece being ejected at high speed, posing a direct life safety threat to the operator, and further causing delays in the production plan and economic losses.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A flange flanging device, comprising:

[0007] A load-bearing plate, the upper end of the load-bearing plate is fixedly connected with a fixing plate, the upper end of the fixing plate is fixedly connected with a motor, the upper end of the fixing plate is fixedly connected with a protective shell, the output end of the motor is fixedly connected with a rotating plate, an L-shaped plate is arranged at the upper end of the rotating plate, a rotating groove is opened at one end of the L-shaped plate, one end of the rotating plate is fixedly connected with a connecting column, the L-shaped plate is sleeved on the outer circumferential surface of the connecting column through the rotating groove, a pressure ring is fixedly connected to one end of the L-shaped plate, a clamping ring is fixedly connected to the other end of the L-shaped plate, a connecting groove is opened at one end of the clamping ring, a magnetic attraction ring is fixedly connected to one inner wall of the connecting groove, and a working plate is fixedly connected to the pressure ring.

[0008] As a preferred embodiment of the present utility model, two connecting rods are fixedly connected to the upper end of the load-bearing plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In this solution, multiple L-shaped plates rely on their own weight to keep the pressure ring at a relatively high position. At this time, the clamping ring is in a relaxed state. When the material is placed on the surface of the working plate, the weight of the material acts on the pressure ring, causing it to move downward. According to the lever principle, one end of the L-shaped plate descends with the pressure ring, while the other end is lifted upward through the action of the rotating groove, driving the clamping ring and the built-in magnetic ring therein to move towards the material, and finally firmly clamping the material, ensuring the stability of the material during subsequent processing or operation, and at the same time improving the overall working efficiency and safety.

[0015] 2. In this solution, the combined use of the telescopic rod and the return spring in the device provides additional dynamic balance and shock absorption effects, which helps to reduce the vibration caused by material characteristics and operations during processing, ensuring the stability of processing and the integrity of the workpiece. At the same time, the setting of the stress block and the protective shell further enhances the safety of the operation and effectively prevents accidents from occurring.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0025] A flange flanging device, comprising:

[0026] A load-bearing plate 1, the upper end of the load-bearing plate 1 is fixedly connected with a fixing plate 2, the upper end of the fixing plate 2 is fixedly connected with a motor 3, the upper end of the fixing plate 2 is fixedly connected with a protective shell 4, the output end of the motor 3 is fixedly connected with a rotating plate 5, the upper end of the rotating plate 5 is provided with an L-shaped plate 6, one end of the L-shaped plate 6 is provided with a rotating groove 7, one end of the rotating plate 5 is fixedly connected with a connecting column 8, the L-shaped plate 6 is sleeved on the outer circumferential surface of the connecting column 8 through the rotating groove 7, one end of the L-shaped plate 6 is fixedly connected with a pressure ring 9, the other end of the L-shaped plate 6 is fixedly connected with a clamping ring 10, one end of the clamping ring 10 is provided with a connecting groove 11, the inner wall of one side of the connecting groove 11 is fixedly connected with a magnetic attraction ring 12, and a working plate 27 is fixedly connected to the pressure ring 9.

[0027] In a specific embodiment of the present utility model, when the device is in use, first, the flange is placed on the working plate 27, and the working plate 27 is supported by the pressure ring 9. When the flange is placed in place, due to the weight of the flange, the pressure ring 9 will move downward, thereby driving one end of the L-shaped plate 6 to descend. By utilizing the cooperation of the rotating groove 7 and the connecting column 8, the other end of the L-shaped plate 6 will lift upward. This action causes the clamping ring 10 and the built-in magnetic ring 12 to move towards the flange, and the magnetic ring 12 adsorbs on the flange in cooperation with the clamping force of the clamping ring 10, thereby realizing the firm clamping of the flange. At this time, the motor 3 is started, and the L-shaped plate 6 is driven to rotate through the rotating plate 5, thereby enabling the flange clamped at the end of the L-shaped plate 6 to perform a flanging operation. Through the above device, the stability of the flange fixation is ensured, and the personal safety of the user is improved.

[0028] Specifically, please refer to Figure 2 On the upper end of the load-bearing plate 1, two connecting rods 13 are fixedly connected. On the outer circumferential surface of the connecting rod 13, a receiving block 14 is fixedly connected. On the upper end of the receiving block 14, a telescopic rod 15 is fixedly connected. On the upper end of the receiving block 14, a return spring 16 is fixedly connected. The other end of the return spring 16 is movably connected to a stress block 17. One end of the stress block 17 is sleeved on the outer circumferential surface of the connecting rod 13. The upper end of the stress block 17 is movably connected to a protective shell 26.

[0029] In this embodiment: Through the two connecting rods 13 fixedly connected to the upper end of the load-bearing plate 1 and their supporting receiving blocks 14, this flange flanging device constructs a stable framework, which not only provides structural support for the entire device and creates a safe working environment, but also the combined design of the connecting rod 13 and the receiving block 14 can catch and fix the protective shell 26, making it closely surround the clamping ring 10 to form a closed protection barrier, effectively isolating the operator from the high-speed rotating components such as the motor 3 and the rotating plate 5, thereby greatly reducing the potential operation risks and ensuring the personal safety of the user during the operation of the device. The settings of the telescopic rod 15 and the return spring 16 improve the overall stability and durability of the device. During the processing, when encountering a flange with too high hardness or irregular shape, strong impacts or vibrations will occur. At this time, the telescopic rod 15 and the return spring 16 work together to quickly absorb and disperse these sudden forces, prevent the protective shell 26 from being directly impacted, and at the same time reduce the burden on the main structure of the device, significantly extending the service life of the device.

[0030] Specifically, please refer to Figure 2, one end of each of the two connecting rods 13 is provided with a moving groove 18. One side inner wall of the two moving grooves 18 is fixedly connected with a second spring 19. One end of the second spring 19 is fixedly connected with a lever 21. The upper end of the lever 21 is fixedly connected with a clamping block 20. A clamping groove 22 is provided in the protective shell 26. The clamping block 20 is movably clamped in the clamping groove 22.

[0031] In this embodiment: The operator only needs to press the lever 21. At this time, the second spring 19 at one end of the clamping block 20 is compressed, so that it moves and disengages from the contact with the clamping groove 22, realizing the quick locking and release of the protective shell 26, simplifying the operation process of protection, ensuring the safety during the operation of the equipment, preventing the operator from accidentally touching the internal components, facilitating the daily maintenance and inspection, and further improving the work efficiency and the usability of the equipment.

[0032] Specifically, please refer to Figure 1 , the lower end of the load-bearing plate 1 is fixedly connected with a plurality of column legs 23. The lower ends of the plurality of column legs 23 are fixedly connected with table mats 24. The closer ends of the plurality of column legs 23 are all fixedly connected with stabilizing plates 25.

[0033] In this embodiment: The lower end of the load-bearing plate 1 is fixed by a plurality of column legs 23. The table mats 24 at the bottom of each column leg 23 enhance the friction with the ground, contributing to anti-slip and shock absorption. There are stabilizing plates 25 between the column legs 23. This design strengthens the structural stability and ensures the firmness and non-displacement of the device during use.

[0034] The working principle and usage process of the present utility model: Place the material flange on the working plate 27, so that its own gravity causes the pressure ring 9 to move downward, triggering one end of the L-shaped plate 6 to descend, and the other end rises by means of the rotating groove 7 and the connecting column 8, pushing the clamping ring 10 and the magnetic attraction ring 12 to adsorb the flange to achieve stable clamping. The motor 3 is started, and the L-shaped plate 6 is driven to rotate through the rotating plate 5 to flang the flange, ensuring the safety and stability of the operation.

[0035] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
