In the above embodiment, the metal plate is placed on the punching position of the material returning plate 122, under the driving of the punching driving member 111, the metal plate is clamped between the limiting cylinder 1121 and the material returning plate 122, and under the continued driving of the punching driving member 111, the material returning plate 122 drives the sleeve 23 to move down to compress the second spring 24, so that the lower die 121 extrudes the metal plate and further pushes the upper die 113, the first spring 114 is compressed, the upper die 113 drives the U-shaped plate 115 to move up relative to the limiting cylinder 1121, in the process of moving up relatively, the abutting block 1191 is located in the restraining groove, the outer end of the elastic plate 1152 is in frictional contact with the groove wall of the side groove 1123, when the upper die 113 is abutted to the upper die 113 against the abutting switch 116, so that the abutting switch 116 starts the third telescopic member 117, the third telescopic member 117 drives the connecting plate 1171 to move down, and accordingly the abutting plate 119 is driven to move out along the restraining groove through the connecting rod 118, so that the abutting block 1191 protrudes out of the restraining groove, and after the end of punching, the upper die 113 drives the side plate 115 to move down relative to the limiting cylinder 1121 under the elastic force of the first spring 114, the side plate 1151 against the side plate 1121, when the abutting plate 1152 is pressed against the metal plate 1123, and the chip plate is extruded by the side plate 1122, and the chip is extruded on the side plate 1122, and the chip is prevented from moving down, and the chip plate is intermittently and the chip is extruded on the side plate 1122, and the chip is cut, and the chip is prevented from being intermittently pressed down on the surface side surface plate surface of the metal plate and the chip plate is pressed.
With continued reference to fig. 1, in the blanking direction, a blanking box 5 is disposed at a front position of the table 3, and a feeding port 51 is disposed at a position of the blanking box 5 adjacent to a table surface of the front material guiding plate 31. The sheet metal part after stamping is pushed into the feed inlet 51 and falls into the blanking box 5, and a buffer pad is arranged on the inner wall of the blanking box 5 to buffer and protect the sheet metal part, so that a worker can take out the sheet metal part from the blanking box 5 instead of directly taking the sheet metal part from a stamping position, and the safety factor is high.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
