[0032] Referring to Figure 1 and Figure 2 , in a blank pushing structure of a stamping die according to an embodiment of the present utility model, it includes a bottom die assembly 110 and an upper die assembly 100. The upper die assembly 100 can move relative to the bottom die assembly 110. There is a blank 106 to be stamped between the upper die assembly 100 and the bottom die assembly 110. The bottom die assembly 110 is provided with a movable part 115 and a fixed part 116. The movable part 115 is slidably connected to the bottom die assembly 110, and the fixed part 116 is fixedly installed on the bottom die assembly 110. The blank 106 is located between the movable part 115 and the fixed part 116. Referring to Figure 3 , the movable part 115 is provided with a socket hole 117, and the inner peripheral wall of the socket hole 117 has a first conical surface 118. The upper die assembly 100 is provided with a driving rod 103, and the end of the driving rod 103 has a second conical surface 104. During the stamping process, when the upper die assembly 100 moves towards the bottom die assembly 110, the driving rod 103 can be inserted into the socket hole 117 and the second conical surface 104 presses against the first conical surface 118, so that the first conical surface 118 and the second conical surface 104 coincide. The movable part 115 can move along the surface of the bottom die assembly 110 and press against one side of the blank 106, thereby realizing pushing the blank 106, making the other side wall of the blank 106 press against the fixed part 116, realizing clamping the blank 106 by the movable part 115 and the fixed part 116, and thus realizing the positioning of the blank 106 during stamping. When the upper die assembly 100 moves away from the bottom die assembly 110, the driving rod 103 moves away from the socket hole 117, and the movable part 115 does not press against the blank 106. Therefore, the other side wall of the blank 106 does not press against the fixed part 116, and the blank 106 does not directly rub against the movable part 115 and the fixed part 116 during loading and unloading movement, thereby reducing the running resistance to improve production efficiency and being able to avoid damage to the blank 106.

[0033] It can be understood that the upper die assembly 100 is located above the lower die assembly 110. The lower die assembly 110 is fixedly arranged and includes a covering plate 111 and a bottom plate 112. The covering plate 111 covers the bottom plate 112. The fixing member 116 is fixedly installed on the covering plate 111. The movable member 115 is embedded in the bottom plate 112. At the same time, a through groove is provided on the covering plate 111, and the through groove penetrates through the covering plate 111. A channel 113 for the movement of the sheet material 106 is formed between the through groove and the side wall of the bottom plate 112. It can be understood that the sheet material 106 is a continuous material. During stamping, the sheet material 106 stops at a preset position of the lower die assembly 110. After the stamping is completed, the sheet material 106 moves driven by the conveying device and stops when it reaches the next position to be processed. Therefore, the sheet material 106 moves intermittently on the stamping equipment. Specifically, a movable groove 114 is provided in the bottom plate 112, and the movable member 115 is located in the movable groove 114. The movable groove 114 communicates with the channel 113. When the upper die assembly 100 presses down and the driving rod 103 is inserted into the insertion hole 117, the movable member 115 moves towards the channel 113.

[0034] Furthermore, there are at least two movable members 115, driving rods 103 and fixing members 116, which can further improve the clamping stability of the movable member 115 and the fixing member 116 on the sheet material 106. Refer to Figure 4 , a groove 119 is provided on the side wall of the movable member 115. When the movable member 115 is located in the bottom plate 112, the bottom wall of the groove 119 is lower than the top surface of the bottom plate 112. A bolt 120 is provided between the grooves 119 of two adjacent movable members 115. The head of the bolt 120 can cover the bottom wall of the groove 119, so as to limit the two fixing members 116 during the installation process and prevent the movable member 115 from coming out of the movable groove 114. Moreover, when the movable member 115 is located in the bottom plate 112, the bottom wall of the groove 119 is lower than the top surface of the bottom plate 112, and the head of the bolt 120 does not contact the bottom wall of the groove 119 after the bolt 120 is tightened, so that the movable member 115 can slide flexibly.

[0035] Refer to Figure 5, in some other embodiments, a reset member 121 is provided between two adjacent movable members 115. The radially outer side of the reset member 121 is elastically abutted against the inner side wall of the groove 119 of two adjacent movable members 115. Specifically, the side wall of the groove 119 is an arc surface, the reset member 121 has a radially outer arc wall. When the movable member 115 moves towards the channel 113, the inner side wall of the groove 119 can press against the radially outer wall of the reset member 121, and the reset member 121 has an elastic pressure on the movable member 115. After the stamping is completed, the driving rod 103 disengages from the insertion hole 117, and the rebound of the reset member 121 can drive the movable member 115 to move away from the channel 113, thereby realizing the reset action of the movable member 115, further reducing the contact between the movable member 115 and the sheet material 106, and reducing the possibility of wear of the sheet material 106. It can be understood that the reset member 121 can be made of elastic materials such as silica gel, rubber, polyurethane, etc.

[0036] Referring to Figure 2 , an elastic member 105 is provided in the upper die assembly 100. The elastic member 105 abuts against one end of the driving rod 103 facing away from the lower die assembly 110. It can be understood that in the embodiment of the present application, the elastic member 105 is selected as a spiral spring, so that the driving rod 103 has a large telescopic formation. When the upper die assembly 100 is pressed down, the driving rod 103 is elastically pressed against the movable member 115 under the push of the elastic member 105, avoiding hard contact and thus preventing impact or breakage. Further, the upper die assembly 100 includes an upper plate 102 and a mounting plate 101. The mounting plate 101 is located on the side of the upper plate 102 facing away from the lower die assembly 110. The elastic member 105 is located in the mounting plate 101, and the driving rod 103 is movably connected to the upper plate 102.

[0037] Referring to Figure 6 , a plug-in groove 123 is provided on the covering plate 111. The plug-in groove 123 is used to install the fixing member 116. It can be understood that the plug-in groove 123 communicates with the channel 113, so that the fixing member 116 can contact the sheet material 106. A protrusion 122 is provided at the upper end of the fixing member 116. The protrusion is located at any corner of the fixing member 116, and the protrusion can also be provided on any edge of the fixing member 116. A positioning groove 124 for accommodating the protrusion 122 is provided on one side of the plug-in groove 123. During installation, the positioning of the fixing member 116 can be realized through the cooperation of the protrusion 122 and the positioning groove 124, avoiding installation errors. Further, a bolt 120 is provided on the covering plate 111. The bottom wall of the head of the bolt 120 can press against the top wall of the fixing member 116, thereby preventing the fixing member 116 from disengaging from the plug-in groove 123 and realizing stable installation. The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
