[0024] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] Reference Figure 1 and Figure 2 , an anti-rebound shaping device, comprising a lower die mechanism 1, an upper die mechanism 2, a forming mechanism 3 arranged on the upper die mechanism 2, and a shaping mechanism 4 arranged on the upper die mechanism 2. When the anti-rebound shaping device is in operation, the upper die mechanism 2 drives the forming mechanism 3 and the shaping mechanism 4 to the lower die mechanism 1 to shape and shape the material. After the material is formed, a preliminary shape is formed, and then the material is immediately sent to the shaping mechanism 4 for shaping and punching. After shaping, the material can avoid rebound, thereby ensuring the material yield.

[0030] Specifically, the lower mold mechanism 1 is provided with a lower mold assembly for adapting to the shape of the material. The lower mold assembly supports the material to adapt to the upper mold mechanism 2. The molding mechanism 3 is driven by the upper mold mechanism 2 and cooperates with the lower mold mechanism 1 to perform preliminary molding of the material. The specific structures and working principles of the lower mold mechanism 1, the upper mold mechanism 2 and the molding mechanism 3 are all existing technologies and will not be repeated here.

[0031] Reference Figure 2 and Figure 3 The shaping mechanism 4 includes a first shaping component 41, a punching component 42, a second shaping component 43 and a third shaping component 44 which are sequentially arranged on the upper die mechanism 2 and driven by the upper die mechanism 2; the first shaping component 41, the punching component 42, the second shaping component 43 and the third shaping component 44 are all facing the material. The first shaping component 41 performs the first shaping and pre-pressing on the material, the punching component 42 punches the designated position of the material, and the second shaping component 43 and the third shaping component 44 perform the second shaping and the third shaping on the material respectively.

[0032] Reference Figure 3 and Figure 4 In this embodiment, the first shaping component 41 includes a first connecting block 411 and a plurality of first shaping blocks 412 arranged on the upper mold mechanism 2. The first connecting block 411 faces the connecting part of the material. The first connecting block 411 extends along the connecting part of the material. Under the drive of the upper mold, the first connecting block will be pressed down and pressed against the connecting part of the material. The first shaping block 412 faces the main part of the material. In order to adapt to the shape of the material, the first shaping block 412 includes a plane block and a transition block. The transition block has an arc. When the first shaping block 412 is pressed down, the plane block will be snapped on the plane part of the material, and the transition block will be snapped on the bending part of the material, thereby completely covering the material for shaping. It can be understood that the plane block and the transition block can be specifically integrated or two separate independent blocks.

[0033] Reference Figure 4 and Figure 5In addition, the plane block of the first shaping block 412 and the first connecting block form a first shaping groove 4121, and the first shaping groove 4121 corresponds to the position of the material hole. By setting the first shaping groove 4121, when the first shaping block 412 presses down to shape the material, it is beneficial to release the stress inside the material. At the same time, the first shaping component 41 also includes a first pre-pressing block 413, which is located above the first shaping groove 4121 and faces the position of the material hole. The first pre-pressing block 413 has a pre-pressing end 4131 and faces the first shaping groove 4121. The movement of the first pre-pressing block 413 and the first shaping block 412 is independent of each other, so that the pre-pressing end 4131 is penetrated through the first shaping groove 4121 and abuts against the material. By setting the pre-pressing end 4131, after the first shaping block 412 shapes the main part of the material and releases the stress, the pre-pressing end 4131 pre-presses the specific opening part of the material to ensure the flatness of the specific part, thereby facilitating the subsequent punching assembly 42 to perform punching.

[0034] Reference Figure 5 and Figure 6 The punching assembly 42 includes a punching positioning block 421 and a punching block 422 which are arranged on the upper die mechanism 2. The punching positioning block 421 is located above the specific opening position of the material. The punching positioning block 421 is provided with a positioning hole 4211. When the punching positioning block 421 is pressed down, the positioning hole 4211 will be located directly above the specific opening position of the material. The punching block 422 is provided with a punching tool (not shown in the figure). The punching tool is driven by the punching block 422 and faces the positioning hole 4211. The punching tool is slidably connected to the positioning hole 4211. When drilling a hole in the material, the punching positioning block 421 is first pressed down to the specific opening position of the material, and then the punching block 422 is pressed down. The punching tool approaches the material along the depth direction of the positioning hole 4211 to drill a hole in the material.

[0035] The second shaping component 43 includes a plurality of second shaping blocks 431, and the plurality of second shaping blocks 431 face the main part of the material. When the second shaping blocks 431 are pressed down, the second shaping blocks 431 will contact the part of the material after the hole is opened, thereby reshaping the part of the material after the hole is opened, ensuring the flatness of the part of the material after the hole is opened, and preventing the material from rebounding after the hole is opened. The third shaping component 44 includes a third shaping block 441, and the third shaping block 441 faces the connecting part of the material. The third shaping block 441 mainly reshapes the connecting part of the material after the hole is opened, ensuring the flatness of the connecting part of the material, so as to facilitate subsequent cutting.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
