[0034] It should be noted that when the stamping device of the present application works, the upper die seat 11 can be connected with the driving structure, and under the driving of the driving structure, the upper die seat 11 approaches the lower die set downward, so that the upper punch 12 cooperates with the lower punch 22 to stamp the sheet metal part.

[0035] It can be understood that in the stamping device of the present application, since each extension part 112 of the bearing piece 110 is connected with the first reinforcing piece 120, the first reinforcing piece 120 can strengthen the strength of the extension part 112, so as to reduce the probability of fracture of the extension part 112 in the working process of the stamping device of the present application, and thus improve the overall strength of the pressing plate 100 of the stamping device of the present application.

[0036] In order to make the stamping device of the present application complete the stamping of multiple sheet metal parts at one time, in some embodiments of the present application, the pressing plate 100 comprises a plurality of bearing pieces 110 and a plurality of first reinforcing pieces 120, one upper punch 12 is arranged on each bearing piece 110, the pressing plate 100 further comprises a connecting piece 130, the bearing pieces 110 are distributed circumferentially around the connecting piece 130, and the central part 111 of the bearing piece 110 is connected with the connecting piece 130; the stamping lower die 20 comprises a plurality of lower punches 22, and the lower punches 22 and the upper punches 12 are one-to-one corresponding in number.

[0037] For example, as shown in the drawings, Figure 3 The pressing plate 100 comprises two bearing pieces 110 and two first reinforcing pieces 120, the two bearing pieces 110 are symmetrically distributed in the front and rear directions, and each bearing piece 110 comprises a central part 111 and two extension parts 112, the two extension parts 112 of the same bearing piece 110 are connected with the same first reinforcing piece 120.

[0038] It can be understood that since the pressing plate 100 includes multiple supporting members 110, and each supporting member 110 is equipped with an upper punch 12, in the stamping device of the present application, multiple upper punches 12 can be installed on the same pressing plate 100, and thus, the stamping device of the present application can stamp multiple sheet metal parts at the same time.

[0039] It is understandable that, since the central portions 111 of the respective bearing members 110 of the pressing plate 100 are connected via the connecting member 130 , the respective bearing members 110 can be connected to each other to form a whole, thereby improving the overall strength of the pressing plate 100 .

[0040] In order to further improve the strength of the extension portion 112 on the pressing plate 100, in some embodiments of the present invention, reference is made to Figure 3 The pressure plate 100 further includes a plurality of second reinforcement members 140 . A second reinforcement member 140 is provided between any two adjacent bearing members 110 . The opposite ends of the second reinforcement member 140 are respectively connected to two adjacent extension portions 112 on the two adjacent bearing members 110 .

[0041] For example, Figure 3 As shown, the pressure plate 100 includes two supporting members 110, and the two supporting members 110 are symmetrically distributed along the front-to-back direction. Each supporting member 110 includes a central portion 111 and two extension portions 112, and the two extension portions 112 are respectively connected to the left and right ends of the central portion 111; the pressure plate 100 includes two second reinforcement members 140, and the two second reinforcement members 140 are distributed along the left-to-right direction. The two extension portions 112 on the left side of the pressure plate 100 are respectively connected to the front and rear ends of the second reinforcement member 140 on the left side, and the two extension portions 112 on the right side of the pressure plate 100 are respectively connected to the front and rear ends of the second reinforcement member 140 on the right side.

[0042] It can be understood that by providing the second reinforcement 140, the various extension portions 112 in the pressure plate 100 can be connected to each other under the joint connection action of the first reinforcement 120 and the second reinforcement 140, thereby making each extension portion 112 have higher strength and making the pressure plate 100 as a whole have higher strength.

[0043] In some embodiments of the present invention, the second reinforcement member 140 includes a reinforcement portion 141 and two connecting portions 142, the two connecting portions 142 are respectively connected to the opposite ends of the reinforcement portion 141, and the end of the connecting portion 142 away from the reinforcement portion 141 is connected to the extension portion 112, and the reinforcement portion 141 and the two connecting portions 142 together constitute a groove structure with an opening toward the connecting member 130.

[0049] In some embodiments of the utility model, referring to Figure 2 , the upper stamping die 10 further comprises an elastic connection structure (not shown in the figure) and a plurality of flanging members 13 arranged on the upper die seat 11, the plurality of flanging members 13 are arranged around the upper punch 12, and the lower end face of the flanging member 13 is located on the upper side of the lower end face of the upper punch 12, the pressing plate 100 is arranged on the upper die seat 11 in an up-and-down floating manner through the elastic connection structure, so that the flanging member 13 can move downward relative to the upper punch 12 to perform flanging on the sheet metal part when the upper punch 12 cooperates with the lower punch 22 to perform stamping on the sheet metal part.

[0050] It should be noted that when the stamping device of the present application works, the sheet metal part can be placed on the lower punch 22, under the driving of the driving structure, the stamping upper die 10 can be close to the stamping lower die 20 downward, so that the upper punch 12 cooperates with the lower punch 22 to stamp the sheet metal part, with the stamping upper die 10 continuing to close to the stamping lower die 20, the elastic connection structure is compressed, so that the flanging part 13 can continue to follow the upper die holder 11 to move downward relative to the upper punch 12, so that the flanging part 13 can flange the edge of the sheet metal part downward.

[0051] In a further embodiment of the present application, the elastic connection structure is a nitrogen spring.

[0052] It can be understood that the nitrogen spring has small volume, large elastic force, and stable work, and has a long service life.
