[0002] In the field of metal processing, especially during the process of using a three-roll plate rolling machine to curl a plate into an unclosed cylindrical shape, the subsequent material hoisting is a crucial link; the traditional method mainly relies on a crane cooperating with a steel wire rope and a hook for hoisting operations; however, this method has exposed a series of problems in actual operation;

[0003] First of all, when directly hoisting the cylindrical material by hooking the two ends of the cylinder with a hook, it is easy to cause the material to shake during the lifting process; this shaking not only increases the instability of the operation, but also may cause the cylinder to be subjected to uneven forces, thereby causing local deformation; especially during long-distance hoisting, the shaking phenomenon is more significant, posing a serious threat to the quality and safety of the material.

[0004] Therefore, it is necessary to provide a new guiding hanger for a three-roll plate rolling machine to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a guiding hanger for a three-roll plate rolling machine.

[0006] The guiding hanger for a three-roll plate rolling machine provided by the utility model includes: a three-roll plate rolling machine body, a main rod and a connecting rod. One end of the three-roll plate rolling machine body is fixedly connected with an extension column. A chute is opened on one side of the extension column. A threaded rod is rotatably connected to the inner wall of the chute. A main rod is slidably connected to the inner wall of the chute. The main rod is threadedly connected with the threaded rod. The bottom end of the main rod is slidably connected with a U-shaped frame. A connecting rod is rotatably connected to the inner wall of the U-shaped frame. A guiding roller is rotatably connected to one side of the connecting rod. An airbag is installed on the other side of the connecting rod.

A lifting motor is fixedly connected to the top end of the extension column. The output end of the lifting motor is fixedly connected to the top end of the threaded rod.

[0008] Preferably, a rotary motor is fixedly connected to one side of the U-shaped frame. One end of the connecting rod close to the rotary motor extends out of the U-shaped frame and is fixedly connected with a worm gear. The output end of the rotary motor is fixedly connected with a worm, and the worm is meshed with the worm gear.

[0009] Preferably, an air pump is fixedly connected to the other side of the U-shaped frame. The output end of the air pump is fixedly connected with a hose, and one end of the hose is connected to the airbag to inflate the airbag.

[0010] Preferably, one side of the three-roll plate bending machine body is rotatably connected with a bracket for supporting the upper roll of the three-roll plate bending machine body, which is used for discharging after flipping.

[0011] Preferably, a driving device is installed on one side of the three-roll plate bending machine body to drive the three-roll plate bending machine body.

[0012] Preferably, two detachable stop bars are installed at the bottom end of the three-roll plate bending machine body to limit the plate processing area.

[0013] Preferably, the surface of the guiding roller is covered with a wear-resistant material layer to improve the wear resistance of the guiding roller, extend its service life, and reduce the frictional damage to the plate to be rolled.

[0014] Compared with the related technology, the guiding hanger for a three-roll plate bending machine provided by the present utility model has the following beneficial effects:

[0015] Improve production safety: Through the guiding function of the guiding roller during the plate curling process, it effectively prevents the shaking and deformation of the material during processing, reducing the risk of safety accidents caused by unstable operation.

[0016] Enhance material stability: Whether in the processing or hoisting stage, the coordinated action of the guiding roller and the airbag greatly enhances the stability of the material. The close fit of the guiding roller and the uniform lifting of the airbag jointly ensure the smoothness of the material during the entire processing process, avoiding local damage or deformation caused by uneven stress.

[0017] Improve production efficiency: The guiding hanger integrates the dual functions of guiding and hoisting, realizing the integrated operation of plate curling, columnar material hoisting and conveying.

[0027] The working principle of the guiding hanging bracket for a three-roll plate bending machine provided by the present utility model is as follows:

[0028] 1. Initial state and preparation

[0029] Equipment startup: Before the sheet is ready for curling processing, the main body 1 of the three-roll plate bending machine starts, and at the same time, the lifting motor 11 is in a standby state. The main rod 5 and the U-shaped frame 6, guiding roller 8 and other components on it are in the initial position;

[0030] Guiding roller position adjustment: At this time, the rotating motor 12 does not work, and the guiding roller 8 naturally hangs down or remains at a preset initial angle through the connecting rod 7 so as not to interfere with the entry of the sheet;

[0031] 2. Sheet processing and guiding

[0032] Sheet curling: When the sheet enters the three-roll plate bending machine for curling processing, according to the processing requirements, the rotating motor 12 is started through the control system; the output end of the rotating motor 12 drives the worm 14 to rotate, and the worm meshes with the worm gear 13, thereby driving the connecting rod 7 and the guiding roller 8 to rotate to the upward position;

[0033] Guiding function: After the guiding roller 8 rotates upward, its surface closely adheres to the outer surface of the sheet. As the sheet curls, the guiding roller plays a guiding and supporting role to ensure that the sheet can be evenly and stably curled into a cylindrical shape;

[0034] 3. Preparation for hoisting the cylindrical material

[0035] Sheet processing completed: When the sheet is completely curled into a cylindrical material, the processing action of the three-roll plate bending machine is stopped;

[0036] Guiding roller position adjustment: The rotating motor 12 is started again, but this time the guiding roller 8 is rotated to the downward position, and at the same time the airbag 9 faces upward; in this way, the airbag can be prepared to inflate and lift the cylindrical material;

[0037] 4. Hoisting and conveying of the cylindrical material

[0038] Airbag inflation: The air pump 15 is started, and air is inflated into the airbag 9 through the hose 16; as the airbag expands, it gradually adheres to and lifts the bottom of the cylindrical material, providing stable support for hoisting;

[0039] Hoisting operation: At this time, an external crane or other hoisting equipment can intervene, and the connection between the cylindrical material and the guiding hanging bracket is released through a hook or other hoisting tool, and the cylindrical material is smoothly lifted for transportation;

[0040] Material transportation: If it is necessary to transport cylindrical materials over a short distance on the ground or between different devices, the lifting motor 11 can be driven to rotate the threaded rod 4, driving the main rod 5 and the U-shaped frame 6 to move up and down along the chute 3. At the same time, the electric push rod 10 can adjust the inclination angle of the U-shaped frame 6 as needed to assist in the stable transportation of the cylindrical materials;

[0041] 5. Safety and Efficiency

[0042] Stability: The guiding function of the guiding roller 8 during the curling process of the plate and the lifting function of the airbag 9 during hoisting jointly ensure the stability of the cylindrical materials during processing, hoisting, and transportation, reducing the risk of shaking and deformation;

[0043] Versatility: This guiding and hanging device can not only play a guiding role during the curling process of the plate, but also realize the hoisting and transportation of the cylindrical materials after processing, improving production efficiency and equipment utilization rate.

[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
