Background technique

Boards are the most common materials in daily life and production and processing, such as wood boards for decoration, metal boards for door frames, and wood boards for splicing. Before the existing plates are used, the edges of the plates, especially the plates, are generally flattened. For example, steel plates for large containers and large-area tiled steel plates are required to be flattened and aligned before welding. Small pieces in the electronics industry Plastic PC boards, etc. also need to be flattened before they are connected to each other. On the one hand, this flattening operation can make the plates neatly stacked during stacking, thereby reducing the occupied space and making it easy to take during production and processing; on the other hand, it can ensure the accuracy of processing and product qualification rate during production and processing.

As shown in Figure 1 and Figure 2, when people are flattening the edge of the plate 1, they usually first place the plate 1 on the working platform 2, and then use the bead 3 to flatten it. This bead 3 is a whole piece The edge of the plate 1 generally warps, that is, the upper surface 11 and the lower surface 12 of the plate 1 are actually uneven, and this unevenness can only be observed after zooming in in some cases.

However, when the existing bead 3 is pressed down, it is always pressed down as a whole, and cannot be deformed accordingly with the unevenness of the edge of the plate 1, so that the raised part of the plate 1 can be partially pressed down, and the plate 1 The concave part of 1 cannot be flattened all the time, and the purpose of flattening the plate 1 cannot be well achieved.

detailed description

Below in conjunction with accompanying drawing 3-10 and specific embodiment the utility model is described in further detail, but they are not limitation of the utility model:

Example 1

As shown in Figures 3 to 12, the flattening device for the edge of the plate includes a bead body 4, the rear end of the bead body 4 is a support portion 41, and the front end array of the bead body 4 is provided with small plates 43, and each small plate 43 There is a gap D between them.

Preferably, a protruding portion 44 is further provided at the bottom of the front end of the small plate 43 .

Preferably, the horizontal cross-section of the protruding portion 44 is polygonal or circular or a combination of both.

Preferably, the front end of the protruding portion 44 is arc-shaped.

Preferably, a first inclined surface 47 with a high front and a low rear is further provided between the bottom of the supporting part 41 and the protruding part 44 , and an angle A is formed between the first inclined surface 47 and the horizontal plane.

Preferably, the end of the first slope 47 is arc-shaped.

Preferably, the bottom of the protruding portion 44 is further provided with a second slope 48 with a low front and a high rear, and the angle B between the second slope 48 and the horizontal plane is provided.

Preferably, the top of the support portion 41 is provided with a first long groove 42 parallel to the longitudinal direction of the bead body 4 .

Preferably, the top array of the supporting portion 41 is provided with second long grooves 45 parallel to the width direction of the bead body 4 .

Preferably, the bottom array of the support portion 41 is provided with third long grooves 46 parallel to the width direction of the bead body 4 .

Specifically, during the flattening process, when pressure is applied to the bead body 4, as shown in Figures 5 and 8, the first long groove 42 at the top of the support part 41 will be deformed by force, thereby exerting pressure on the bead body 4. The upper force produces a cushioning effect, which improves the pressure bearing capacity of the bead body 4.

There is a first slope 47 between the bottom of the support part 41 and the protrusion 44, and the bottom of the protrusion 44 has a second slope 48. When the bead body 4 is pressed, the contact area between the protrusion 44 and the edge of the plate 1 to be pressed is small. , the pressure at the edge of the plate to be pressed 1 as shown in Fig. 5 and Fig. 12 will be amplified so as to achieve a good flattening effect on the edge of the plate to be pressed 1 . Wherein the rear end of the bottom of the support part 41 can be provided with a horizontal part at a certain distance first, and then the first slope 47 is set, thereby ensuring the contact area between the bottom of the support part 41 and the plate 1 to be pressed, and preventing the bottom of the support part 41 from contacting the plate 1 during the pressing process. The contact area of the plate to be pressed 1 is too small to damage the plate to be pressed 1 .

When the applied pressure gradually increases, as shown in Figure 5 and Figure 8, the bottom of the support part 41 and the bottom of the protruding part 44 will gradually deform, so that the angle A gradually becomes smaller and finally becomes the angle C , and the angle of the included angle B gradually decreases and finally becomes zero, then in the process of gradually increasing the applied force, the contact area between the bottom of the support part 41 and the plate to be pressed 1 and the contact area between the bottom of the protruding part 44 and the plate to be pressed The contact area at the edge of 1 is constantly increasing, thereby slowing down the growth rate of the pressure on the plate 1 to be pressed, and avoiding damage to the plate 1 to be pressed due to excessive pressure increase during the flattening process. In addition, during the deformation process of the bottom of the support part 41, as shown in Figure 6, because the end of the first slope 47 is arc-shaped, the first slope 47 will be gently attached to the surface of the plate to be pressed 1 when the bottom of the support part 41 is deformed. close without scratching the surface of the plate 1 to be pressed. Similarly, as shown in Figure 7, because the front end of the protruding part 44 is also arc-shaped, although there will be a slight movement in the process of deformation of the bottom of the protruding part 44, it will not cause damage to the surface of the plate to be pressed 1, ensuring the pressing Product quality in the flat process.

During the pressing process of the bead body 4, the force received by the bead body 4 is evenly distributed to each small plate 43 and finally reaches the protrusion 44 of each small plate 43, and because there is a gap D between each small plate 43, Then as shown in Figure 12, each small plate 43 will have different degrees of deformation when the uneven edge of the plate to be pressed 1 is flattened, so that the protrusion 44 on each small plate 43 The upper convex portion of the edge of the plate to be pressed 1 and the The lower concave parts can play a good flattening effect, and finally flatten the edge of the plate to be pressed 1 to the state shown in FIG. 12 , ensuring the flatness of the plate to be pressed 1 after being flattened.

In addition, in actual production operations, the bead body 4 is generally made of metal materials, and of course it can also be made of other materials according to the situation. After the bead body 4 is manufactured, as shown in FIG. 10 or FIG. There will be a certain degree of deformation, that is, warping. The longer the bead body 4 is, the more serious the warping will be. When the bead body 4 is used for a long time, the warping will be more serious. In this case, Because the top of the support part 41 has the second long grooves 45 arranged in an array, and the bottom of the support part 41 has the third long grooves 46 arranged in an array, only a small pressure on the bead body 4 can be applied to the second long grooves 45, Under the action of the third long groove 46, the warping phenomenon of the bead body 4 is well corrected, so that it returns to the normal state as shown in FIG. 9 .

In a word, the above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent application scope of the present utility model shall fall within the scope of the present utility model.
