The existing flanging punch structure is designed according to the shape of the part. For some parts with large overall deformation caused by flanging, the profiling design cannot be very accurate, which makes it difficult to ensure the overall shape and position accuracy of this structure. Utility Model Content

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0017] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0018] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0020] like Figure 1-3 As shown, a preferred embodiment of the utility model provides a flanging groove pressing structure for preventing overall deformation of a thin plate part, comprising an upper template 1, a flanging punch 3, a flanging die 4, a partition product 6, a supporting plate 7, a material removal spring 8, and a lower bottom plate 9.

[0021] The flanging punch 3 is fixed to the bottom end of the upper template 1, the flanging die 4 is fixed to the lower bottom plate 9, the support plate 7 is fixed to the lower bottom plate 9 through the material withdrawal spring 8, and the flanging die 4 and the flanging punch 3 are separated by a certain distance in the horizontal direction; the upper template 1 is driven by the driving mechanism to move downward; the partition product 6 is placed on the support plate 7 and the flanging die 4 at the same time;

[0022] When the flanging convex die 3 presses the supporting plate 7 downward until the surface of the supporting plate 7 is lower than the surface of the flanging concave die 4, the partition product 6 will be partially bent between the flanging concave die 4 and the flanging convex die 3. A boss 10 is provided at the bottom of the flanging convex die 3.

[0023] In the above technical scheme, the partition product 6 is placed on the supporting plate 7 and the flanging die 4 at the same time. As the upper template 1 moves downward, the flanging punch 3 presses the supporting plate 7 downward until the surface of the supporting plate 7 is lower than the surface of the flanging die 4. The partition product 6 will be partially bent between the flanging die 4 and the flanging punch 3. At this time, the flanging of the partition product 6 is completed. When the supporting plate 7 reaches the stroke limit, the boss 10 acts on the root of the flanging arc of the part to press a groove of suitable depth at the corresponding position on the inner surface of the part. The specific size is designed according to the part thickness and thinning requirements.

[0024] When the material needs to be removed after the flanging is completed, the upper template 1 is controlled to move upward, at which time the stripping spring 8 rebounds and pushes the stripping plate 7 upward to realize product stripping.

[0025] In another technical solution, the flanging punch 3 is fixed to the bottom of the upper mold plate 1 through a punch pad 2 , and the flanging die 4 is fixed to the lower base plate 9 through a die pad 5 .

[0026] In another technical solution, one end of the supporting plate 7 close to the flanging die 4 protrudes to form a protrusion; relative to the die pad 5, the flanging die 4 is closer to the flanging punch 3, and the protrusion is close to the die pad 5.

[0027] In the above technical solution, the flanging die 4 which is closer is used to limit the upper and lower positions of the protrusions of the stripper plate 7, so as to avoid the problem that the stripper plate flies upwards too far during the up and down movement.

[0028] In another technical solution, a groove is provided on the surface of the lower bottom plate 9 , one end of the material removal spring 8 is vertically arranged in the groove, and the other end is connected to the stripping plate 7 .

[0029] In the above technical solution, the material withdrawal spring 8 is arranged in the groove, which can play a certain limiting role on the material withdrawal spring 8 and is more stable during the deformation process.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
