Description

Mechanical keyboard plate flattening device

technical field

The utility model relates to the technical field of mechanical equipment, in particular to a flattening device for a mechanical keyboard plate.

Background technique

The mechanical keyboard plate is a metal plate, which needs to be in a flat state during use, but the metal plate is more prone to plastic deformation during the production process. In order to solve the above problems, a flattening machine is generally used at present to flatten the plastically deformed metal plate. Existing flattening machines usually place the metal plate on a flat workbench, and apply downward pressure on the warped position of the metal plate to flatten and straighten it. Although this flattening method can alleviate the problem to a certain extent The plastic deformation of the metal plate, but because the support table is set in a plane, when the bent metal plate is corrected, the bent metal plate can only be pressed into a flat state, but because the metal itself has a certain elasticity, the pressure applied downward After undoing, the sheet metal deforms elastically and still has a small bend, which results in a less than good flattening effect.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a mechanical keyboard plate flattening device provided by the utility model is used to flatten the mechanical keyboard plate 100 whose edge is upturned. The mechanical keyboard plate 100 is made of metal material and is used as a keyboard. The housing of the mechanical keyboard 100 is provided with rows of mounting holes (not shown) at positions corresponding to the keys on the keyboard. It can be understood that the mechanical keyboard plate flattening device can also be used for flattening processing of other metal plate parts.

The flattening device of the mechanical keyboard comprises a frame 10, a mounting frame 20, a pressing roller device 30, a trimming jig 40 and a driving device 50. A workbench 11 is arranged on the top of the frame 10, and the mounting frame 20 is installed On the workbench 11, the press roller device 30 is installed on the mounting frame 20, the trimming jig 40 is arranged on the workbench 11 and is set up and down opposite to the press roller device 30, and the mechanical keyboard The plate 100 is placed on the upper surface of the trimming jig 40 , the driving device 50 is mounted on the mounting frame 20 , and the driving device 50 drives the pressure roller device 30 to move downward and roll on the mechanical keyboard plate 100 .

The installation frame 20 includes four support rods 21 and an installation platform 22 , and the driving device 50 is installed on the installation platform 22 . The pressure roller device 30 includes a lifting platform 31, a telescopic device 32 and a plurality of pressure rollers 33. The lifting platform 31 is installed on the four support rods 21 of the installation frame 20, and the driving device 50 can drive the lifting platform 31. Move up and down along the support rod 21. The bottom of the lifting platform 31 is provided with a mounting rod 34 , the pressure roller 33 is installed in the middle of the mounting rod 34 , and the telescopic device 32 is mounted on the mounting rods 34 on both sides of the pressure roller 33 . In this embodiment, the telescopic device 32 is a spring, and the number of the pressing rollers 33 is two. The two pressure rollers 33 are arranged side by side along the extending direction of the installation rod 34 .

The trimming jig 40 is fixed on the upper surface of the workbench through a fixing piece, and the upper surface of the trimming jig 40 is arranged in an arc shape. Specifically, the trimming jig 40 is arranged in an arc shape with a protruding middle part and an arc extending downwards from the middle part to the two outer sides. The mechanical keyboard board 100 is placed centrally on the upper surface of the trimming jig 40 . The bottom of the frame 10 is also provided with rollers to facilitate the movement of the mechanical keyboard flattening device.

When working, the driving device 50 drives the pressing roller 33 to move downward until the pressing roller 33 is pressed against the middle part of the mechanical keyboard plate 100, and the driving device 50 still drives the pressing roller 33 to move downward, and because the trimming tool 40 is an arc-shaped structure with a high middle part and low sides. According to the principle of mechanical force balance, the pressure roller 33 will be subjected to a pressure along the inclined direction of the inclined surface of the trimming fixture. Under the action of this pressure, the pressure roller 33 will 33 compresses the telescopic device 32 outward and rolls the mechanical keyboard plate 100 outward along the inclined surface. After this operation is completed, the driving device 50 drives the pressure roller 33 to rise, because the pressure roller 33 is only subjected to an upward force, and there is no lateral pressure to compress the telescopic device 32, the telescopic device 32 will rebound to the original position, thereby pushing the pressure roller The roller 33 returns to the middle of the mounting bar 34 . Since the mechanical keyboard plate 100 will have a certain rebound after being flattened, the radian setting of the trimming jig 40 can properly flatten the mechanical keyboard plate 100 in the opposite direction of the raised edge, thereby offsetting its rebound effect. The radian makes the mechanical keyboard board 100 flat.
