Description

Technical Field

[0001] The utility model relates to the technical field of trailer sheet metal processing equipment, and more specifically, to a sheet metal flattening device. Background Art

[0002] Steel is a material with various shapes, sizes, and properties required by steel ingots, billets, or steel through pressure processing. Steel is an essential material for national construction and the realization of the four modernizations. It has a wide range of applications and a variety of varieties. According to different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes, and metal products.

[0003] Currently, a large amount of steel plates are required in the production of trailers. The steel plates need to be transported in the workshop, and mostly lifting equipment is used to lift and transfer the steel plates. During the transfer process, the plates are prone to bending under the action of gravity, and due to the heavy weight of the plates, the plates are also prone to breakage, affecting the quality of the finished products.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: A sheet metal flattening device includes a lifting frame, an electromagnet, and two telescopic tubes. Both the lifting frame and the telescopic tubes are square tube structures. The two telescopic tubes are movably inserted at both ends of the lifting frame. A partition is fixedly installed in the middle of the lifting frame. Driving devices are fixedly installed on both sides of the partition. The driving devices are used to drive the telescopic tubes to move along the axial length direction of the lifting frame. Hook members are fixedly installed at the outer ends of the telescopic tubes. The electromagnet is fixedly installed at the middle of the bottom of the lifting frame. An ear is fixedly installed at the middle of the upper part of the lifting frame.

[0006] Preferably, the hook member includes a sleeve and a slider. The lower end of the sleeve is open. The slider is slidably inserted into the sleeve. A support plate is fixedly installed at the lower end of one side of the slider close to the electromagnet.

[0007] Preferably, the driving device is a screw motor. A threaded shaft sleeve is fixedly installed at one end of the telescopic tube. The screw shaft of the screw motor is in mating connection with the threaded shaft sleeve at the corresponding position.

[0008] Preferably, a notch groove is opened at a position directly above the support plate at one end of the telescopic tube. The depth of the notch groove is equal to the thickness of the support plate.

[0009] Preferably, the cross-sections of the sleeve and the slider are both square.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] In the present utility model, the lifting frame is moved to the position of the sheet material by a lifting device. By adjusting the length of the telescopic tube extended, it is ensured that the overall length of the lifting frame and the telescopic tube can correspond to the length of the sheet material. The electromagnet adsorbs the sheet material. During the lifting process, the hook members can be clamped on both sides of the sheet material and at the same time support the lower part of the sheet material, thereby avoiding the bending of the sheet material during the transfer process, playing a role in leveling, reducing the deformation of the sheet material, and ensuring the quality of the finished sheet material.

[0019] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0020] Refer to Figure 1As shown in the figure, the present utility model provides a flat plate supporting device, which includes a lifting frame 1, an electromagnet 3 and two telescopic tubes 2. The lifting frame 1 and the telescopic tubes 2 are both square tube structures. The two telescopic tubes 2 are movably inserted at both ends of the lifting frame 1. A partition 12 is fixedly installed in the middle of the lifting frame 1. Driving devices are fixedly installed on both sides of the partition 12. The driving devices are used to drive the telescopic tubes 2 to move along the axial length direction of the lifting frame 1. Hook members 4 are fixedly installed at the outer ends of the telescopic tubes 2. The electromagnet 3 is fixedly installed at the middle of the bottom of the lifting frame 1. A hanging ear 11 is fixedly installed at the middle of the upper part of the lifting frame 1.

[0021] To achieve the flattening of the sheet material, refer to Figure 2 As shown in the figure, in this embodiment, the hook member 4 includes a sleeve 41 and a slider 42. The lower end of the sleeve 41 is open. The slider 42 is slidably inserted into the sleeve 41. A support plate 43 is fixedly installed at the lower end of one side of the slider 42 near the electromagnet 3.

[0022] Refer to Figure 3 As shown in the figure, in this embodiment, the driving device is a screw motor 5. A threaded shaft sleeve 22 is fixedly installed at one end of the telescopic tube 2. The screw shaft of the screw motor 5 is in mating connection with the threaded shaft sleeve 22 at the corresponding position.

[0023] Further, when the lifting frame 1 is attached to the surface of the sheet material, to ensure that the electromagnet 3 can smoothly contact the sheet material, refer to Figure 4 As shown in the figure, in this embodiment, a notch groove 21 is provided at a position directly above the support plate 43 at one end of the telescopic tube 2. The depth of the notch groove 21 is equal to the thickness of the support plate 43.

[0024] To prevent the slider 42 from rotating, in this embodiment, the cross-sections of the sleeve 41 and the slider 42 are both square.

[0025] Further, in this embodiment, the lifting frame 1, the telescopic tubes 2 and the hook members 4 are all made of steel structure.

[0026] The specific operation steps are as follows: Hook the lifting frame 1 to the hanging ear 11 position through a lifting device, move the lifting frame 1 to the position of the sheet material, adjust the length of the telescopic tubes 2 extended by the screw motor 5 to ensure that the overall length of the lifting frame 1 and the telescopic tubes 2 can correspond to the length of the sheet material, start the electromagnet 3, and the electromagnet 3 can adsorb the sheet material. When the lifting frame 1 rises, the slider 42 moves downward under the action of gravity. At this time, contract the telescopic tubes 2 through the screw motor 5. At this time, the slider 42 can clamp both sides of the sheet material, and the support plate 43 can support the lower part of the sheet material, thereby preventing the sheet material from bending during the transfer process and playing a role in flattening.
