However, those skilled in the art can understand that the stamping equipment in the present embodiment can be applied in various stamping fields, and cannot be understood as limiting the application scene of the stamping equipment of the present application.

[0054] The embodiments of the present application will be described below in connection with Figures 1-6 .

[0055] According to the embodiments of the present application, a stamping equipment is provided, as shown in Figures 1-4 , comprising: an upper die seat 1, a lower die seat 2, a jacking structure 3 and a pressing structure 4.

[0056] The lower die seat 2 is arranged opposite to the upper die seat 1, and the lower die seat 2 has a first profile surface 201; the lifting structure 3 is arranged on the lower die seat 2 in a liftable manner, and the lifting structure 3 has a second profile surface 3011 and an abutting portion 3012, and the part to be processed is adapted to be placed on the second profile surface 3011; the pressing structure 4 is arranged on the upper die seat 1, and the pressing structure 4 is adapted to abut against the abutting portion 3012 to push the lifting structure 3 so that the second profile surface 3011 is flush with the first profile surface 201, so that the first profile surface 201 and the second profile surface 3011 jointly support the part to be processed.

[0057] In the above embodiment, after the part to be processed is placed on the second profile surface 3011 of the lifting structure 3, the abutting portion 3012 on the lifting structure 3 is pushed by the pressing structure 4, so that the lifting structure 3 is retracted, the abutting portion 3012 and the second profile surface 3011 are lowered at the same time, and then the second profile surface 3011 is flush with the first profile surface 201 on the lower die seat 2, so that the first profile surface 201 and the second profile surface 3011 can be flush to jointly support the part to be processed before the part to be processed is subjected to the stamping operation, that is, the part to be processed is subjected to the stamping operation in the state of completely fitting the first profile surface 201 and the second profile surface 3011, thereby avoiding displacement of the part to be processed relative to the lifting structure 3, and improving the production stability of the stamping equipment.

[0058] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 When the upper and lower die seats are closed to stamp the part to be processed into a body sheet metal part, the upper die seat 1 will first push the lifting structure 3 to retract by abutting against the abutting portion 3012 on the lifting structure 3, so that the second profile surface 3011 of the part to be processed placed on the lifting structure 3 is lowered first, and is flush with the first profile surface 201 on the lower die seat 2, when the first profile surface 201 and the second profile surface 3011 are flush, the part to be processed can also fit with the first profile surface 201 and the second profile surface 3011, so as to ensure the stability of the part to be processed during the stamping operation; in the related art, the upper die seat 1 will push the lifting mechanism to retract after contacting the part to be processed, until the top profile surface of the lifting mechanism is flush with the lower die seat profile surface, and then the stamping of the metal sheet is formally started, which is easy to cause displacement of the part to be processed relative to the lifting mechanism during the retraction of the lifting mechanism, thereby affecting the production stability of the stamping equipment.

[0059] Further, as shown in Figure 3 、 Figure 4As shown, the lower die seat 2 has a first profile 201, which can be machined by the lower die seat 2, or a block structure with the first profile 201 is installed on the lower die seat 2. In this embodiment, the first profile 201 has two parts, and a gap between the two parts is provided with a jacking structure 3. The main structure of the jacking structure 3 is block-shaped, and a second profile 3011 is arranged at the middle position. The part of the jacking structure 3 with the second profile 3011 is arranged in the gap between the two parts of the first profile 201 in a profiling manner. When the first profile 201 and the second profile 3011 are flush, the first profile 201 and the second profile 3011 together form a complete stamping profile, which functions to extrude the parts to be processed when the upper and lower die seats are closed, so that the parts to be processed are pressed into a predetermined shape, thereby forming a vehicle body sheet metal part.

[0060] Further, as shown in Figure 3 In this embodiment, two groups of jacking structures 3, two groups of first profiles 201 matched with the two groups of jacking structures 3, and two groups of pressing structures 4 matched with the two groups of jacking structures 3 are arranged.

[0067] Further, when the pressing-down structure 4 is provided as a rigid structure such as a top rod, by reasonably setting the distance between the top rod and the abutting portion 3012 and the distance between the stamping component on the upper die holder 1 and the first profile 201 on the lower die holder 2, the top rod abuts against the abutting portion 3012 to push the jacking structure 3 so that the first profile 201 and the second profile 3011 are flush, and at the same time, the stamping component on the upper die holder 1 is in contact with the workpiece supported by the first profile 201 and the second profile 3011, that is, the stamping operation can be started after the second profile 3011 is retracted in place.

[0068] In some embodiments, as shown in Figure 2 , Figure 6 , the pressing-down structure 4 is provided as a nitrogen spring.

[0069] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , the jacking structure 3 comprises a jacking block 301 and a rod body 302.

[0074] Further, as shown in Figure 4 , Figure 5 , the top surface of the lifting block 301 is further provided with a positioning column 3013 and a positioning pin 3014, which can correspond to the hole position on the part to be machined, so as to position the position of the part to be machined on the lifting block 301 and the second profile 3011.

[0075] In some embodiments, as shown in Figure 2 , the rod body 302 is arranged in a sleeve shape, and the rod body 302 is provided with an elastic reset member 303.

[0076] In the above embodiment, when the upper and lower molds of the stamping equipment are closed, the lifting block 301 is pressed down by the pressing-down structure 4, so that the elastic reset member 303 is compressed; when the stamping is completed and the mold is opened, the elastic reset member 303 releases the elastic force, so that the rod body 302 and the lifting block 301 are lifted together, the body sheet metal part to be machined is lifted upward, and the demolding is realized.

[0077] Specifically, as shown in Figure 2 , the lower end of the rod body 302 is in an open shape, the elastic reset member 303 is assembled in the rod body 302, and the lower end of the elastic reset member 303 protrudes from the lower end of the rod body 302.
