[0031] This embodiment provides a stamping and flanging device. Figures 1 to 3 As shown, the stamping and flanging device comprises an upper shell 1 and a lower shell 2. The upper shell 1 includes a driving block 11, with a sliding guide 12 disposed at its lower end. A flanging punch 13 is disposed below the sliding guide 12. The flanging punch 13 comprises a body 131 and a punch head 132. The sliding guide 12 is slidably connected to the body 131, and the punch head 132 is located below the body 131. The punch head 132 is integrally formed with the body 131. Both the body 131 and the punch head 132 are cylindrical in shape, and the outer periphery of the body 131 near the punch head 132 is configured as a stepped structure with a gradually decreasing diameter. The lower shell 2 is located below the upper shell 1 and has an inclined telescopic hole 21. The body 131 is slidably connected to the telescopic hole 21. Lowering the upper shell 1 relative to the lower shell 2 causes the sliding guide 12 to slide relative to the body 131, thereby forcing the punch head 132 to extend outward from the telescopic hole 21.

[0032] In this embodiment, when the stamping and flanging equipment is in use, the upper shell part 1 moves downward toward the lower shell part 2 under the driving action of the external lifting equipment. During the process, the driving block 11, the sliding guide plate 12 and the flanging punch 13 move downward together toward the lower shell part 2. When the sliding guide plate 12 moves to contact the lower shell part 2, the upper shell part 1 continues to move downward, so that the driving block 11 pushes the sliding guide plate 12 and the flanging punch 13 to produce a relative sliding trend, so that the main body 131 of the flanging punch 13 slides downward relative to the telescopic hole 21. During the process, the punch head 132 gradually extends out of the telescopic hole 21 from below the telescopic hole 21, so that the hole structure on the vehicle panel below can be flanging.

[0033] In this embodiment, by integrally forming the punch head 132 and the main body 131, the area of ​​effective connection between the punch head 132 and the main body 131 can be increased, and the overall strength of the flanging punch 13 is enhanced. By setting the main body 131 and the punch head 132 to be cylindrical, and setting the outer periphery of the main body 131 near the punch head 132 to a stepped structure with a gradually decreasing diameter, the problem of stress concentration at the diameter-changing portion caused by the excessive diameter between the punch head 132 and the main body 131 can be reduced to a certain extent, and the overall strength of the flanging punch 13 can also be enhanced. The punch head 132 is firm and not easy to break, has a simple structure, is highly practical, and the flanging punch 13 has reliable strength.

[0034] In this embodiment, the body 131 and the punch 132 are integrally cast. Since the structures of the body 131 and the punch 132 are relatively simple, the integral casting method is convenient to operate and can ensure the overall reliable strength of the flanging punch 13.

[0035] In this embodiment, a receiving groove 133 is formed on the periphery of the main body 131, and the sliding guide plate 12 is slidably disposed within the receiving groove 133. The provision of the receiving groove 133 facilitates the sliding guide plate to extend into the receiving groove 133 and facilitates the sliding guide plate to abut against the upper portion of the main body 131.

[0036] In this embodiment, a sliding head 111 protrudes from the driving block 11 and is slidably connected to the receiving groove 133. When the driving block 11 is lifted upward, the sliding head 111 can support the upper end wall of the receiving groove 133, thereby lifting the flanging punch 13 as a whole, thereby completing the retraction operation of the flanging punch 13 relative to the telescopic groove.

[0037] In this embodiment, the main body 131 and the punch head 132 are coaxially arranged, which results in a simple structure and convenient processing.

[0038] In some optional embodiments, the body portion 131 and the punch portion 132 are fixedly connected via a transition portion 134. Specifically, since the diameter of the punch portion 132 is smaller than that of the body portion 131, the provision of the transition portion 134 can smooth the diameter difference between the punch portion 132 and the body portion 131, and can also alleviate the problem of stress concentration at the diameter change portion caused by an excessively large diameter transition between the punch portion 132 and the body portion 131, thereby enhancing the overall strength of the flanging punch 13.

[0039] Optionally, the transition portion 134 is configured as a transition chamfer or a transition fillet.

[0040] In some optional embodiments, a cushioning sleeve 22 is disposed between the main body 131 and the telescopic hole 21. Specifically, the cushioning sleeve 22 is sheathed around the outside of the main body 131. During the process of the main body 131 extending or contracting relative to the telescopic hole 21, the cushioning sleeve 22 always contacts the inner wall of the telescopic hole 21. This arrangement prevents wear and tear caused by long-term sliding, hard contact between the main body 131 and the telescopic hole 21, effectively extending the service life of the flanging punch 13.

[0041] Optionally, the material of the buffer sleeve 22 is set to rubber. Rubber material has good buffering effect and low cost.

[0042] Optionally, the material of the flanging punch 13 is set to alloy steel. Specifically in this embodiment, the material of the flanging punch 13 is set to alloy steel SkD11.

[0043] This embodiment is not limited to this, and the material of the flanging punch 13 can also be set to other types and models, and no further restrictions are made here.

[0044] In summary, the stamping and flanging equipment provided in this embodiment has a simple structure and strong practicality. The flanging punch 13 has reliable strength, and the punch head 132 is firm and not easy to break.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
