Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to a sheet metal flattening device. Background Technology

[0002] During sheet metal processing, internal stress accumulates in the material. The heat input during cutting exacerbates warping, causing the sheet metal to bend on both sides. If stamping is performed directly at this point, the strength of the sheet metal will decrease and the accuracy of the formed sheet metal will be affected due to the bending on both sides and the large internal stress in the material. Therefore, sheet metal needs to be flattened before stamping. For aluminum sheet metal parts, due to the low hardness of the material, it is generally flattened manually using simple tools.

[0003] The current method for flattening aluminum sheet metal parts is to apply force from the top of the sheet metal part downwards to make the surface of the sheet metal part flat. However, this method will cause the sheet metal part to spring back after being pressed. After springing back, the degree of bending of the sheet metal part is not much different from that before pressing. Therefore, multiple pressing is required to make the residual bending of the sheet metal part approach zero and achieve the purpose of correction. Multiple pressing operations not only increase the workload of workers, but also reduce efficiency. Utility Model Content

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0024] This utility model provides a sheet metal flattening device, such as Figure 1 As shown, it includes:

[0025] Rack 1;

[0026] Conveying mechanism 2 is fixedly installed on frame 1;

[0027] The rolling mechanism 3 is detachably installed in the middle of the conveying mechanism 2;

[0028] Heating mechanism 4 is detachably installed on one side of the top surface of conveying mechanism 2 and located at the front end of rolling mechanism 3;

[0029] The cooling mechanism 5 is detachably installed on one side of the top surface of the conveying mechanism 2 and located at the rear end of the rolling mechanism 3.

[0030] A heating mechanism 4 and a cooling mechanism 5 are added to both sides of the rolling mechanism 3. Before rolling the sheet metal, the added heating mechanism 4 heats the sheet metal to improve its plasticity. Then, the sheet metal is flattened to improve the rolling effect. After rolling, the sheet metal is cooled by the cooling mechanism 5 to achieve the shaping of the sheet metal, thereby effectively preventing the sheet metal from springing back after flattening and avoiding repeated pressing of the sheet metal, which greatly improves the efficiency of the work.

[0031] In this embodiment, as Figure 1-2 As shown, the conveying mechanism 2 includes two supports 21 and several guide rollers 22. The two supports 21 are symmetrically and detachably mounted on the frame 1, and the several guide rollers 22 are equidistantly mounted between the two supports 21 for conveying sheet metal parts.

[0032] In this embodiment, as Figure 1-2 As shown, the rolling mechanism 3 includes a reducer 31, a drive roller 32, and a driven roller 33. The reducer 31 is detachably installed at the bottom of the middle of one of the supports 21. The drive roller 32 and the driven roller are rotatably installed in the middle of the two supports 21 and are in an up-down relationship. The reducer 31 is connected to the drive roller 32. During rolling, the reducer 31 drives the drive roller 32 to rotate. When the sheet metal passes between the drive roller 32 and the driven roller 33, the driven roller 33 also moves synchronously with the drive roller 32 under the contact of the sheet metal. The driven roller 33 cooperates with the drive roller 32 to squeeze, align, and level the sheet metal.

[0033] In this embodiment, as Figure 2-3 As shown, the heating mechanism 4 includes a first protective shell 41, an electronic control system 42, and an electromagnetic coil 43. The first protective shell is detachably mounted on two brackets 21. The electronic control system 42 is placed inside the first protective shell 41. The electromagnetic coil 43 is connected to the electronic control system 42 and has a rectangular structure. Its bottom extends to the bottom of the guide roller 22 for the sheet metal to pass through. When the sheet metal passes through the electromagnetic coil 43, the electronic control system 42 generates current and delivers it to the electromagnetic coil 43, causing the sheet metal to generate an alternating magnetic field, thereby achieving the heating treatment of the sheet metal.

[0034] In this embodiment, as Figure 2 , Figure 4 As shown, the cooling mechanism 5 includes a second protective shell 51, a cooling plate 52, a heat sink 53, a centrifugal fan 54, and an air knife 55. The second protective shell is detachably mounted on two brackets 21. The cooling plate 52, the heat sink 53, the centrifugal fan 54, and the air knife 55 are sequentially assembled into the second protective shell 51 from top to bottom. The cooling plate 52 generates low temperature, and the heat sink 53 conducts the cold energy. At this time, the centrifugal fan 54 lowers the cold airflow and delivers it into the air knife 55 and discharges it, thereby cooling the sheet metal that passes through.

[0035] Furthermore, the bottom of the air knife 55 has a long strip structure, and its length is adapted to the width of the conveying mechanism 2, so that the blown cold airflow can be blown to the entire surface of the sheet metal, thereby improving the cooling effect.

[0036] Furthermore, the top surface of the drive roller 32 is flush with the top surfaces of several guide rollers 22 to ensure horizontal conveying of the sheet metal.

[0037] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
