[0039] like Fig.10 and Fig.11 As shown, it also includes a push assembly, which includes a push rod 1501, a push block 1502, a return spring III 1503 and a connecting plate 1505. The bottom surface of the connecting block 701 is symmetrically installed with push rods 1501 by bolts. The lower ends of the two push rods 1501 are respectively provided with push blocks 1502 that can move forward and backward along them.

The rear parts of the two connecting plates 1505 are arranged in an eight-shaped shape, and the two connecting plates 1505 are respectively located directly below the push blocks 1502 on the same side, and the two connecting plates 1505 are respectively connected to the sides of the receiving plates 1401 on the same side that are away from each other by bolts.

[0040] like Figure 1As shown, a collecting component is also included, and the collecting component includes a collecting frame 1601, a sieve plate 1602 and a chip collecting frame 1603. The inner middle part of the support seat 1 is provided with a collecting frame 1601 that can be pulled out from the front thereof, and the collecting frame 1601 is located directly below the placement slot 3. The inner bottom surface of the collecting frame 1601 is provided with a sieve plate 1602, and the sieve plate 1602 will screen the punched sheet metal parts and stamping waste. The inner lower part of the support seat 1 is provided with a chip collecting frame 1603 that can be pulled out from the front thereof, and the chip collecting frame 1603 is located directly below the collecting frame 1601. The stamping waste dropped from the sieve plate 1602 will fall into the chip collecting frame 1603 for collection.

[0041] When it is necessary to perform punching processing on the sheet metal part, the two receiving plates 1401 are close to each other to block the placement slot 3, and then the sheet metal part that needs punching processing is placed in the placement slot 3, and the two receiving plates 1401 will receive it, and then the square punch head 1101 or the round punch head 1102 is selected according to actual needs. If it is necessary to use the square punch head 1101 to punch the sheet metal part, first pull the connecting rod 1203 forward, and the connecting rod 1203 will drive the two blocks 1201 to move forward synchronously, and the reset springs Ⅰ1202 are all compressed, so that the right block 1201 releases the limit fixation on the right connecting rod 1104, and then the tilting rod 1103 is toggled counterclockwise, and the tilting rod 1103 will pass through the left The connecting rod 1104 drives the square punch head 1101 to move downward, and at the same time, the tilting rod 1103 will drive the circular punch head 1102 to move upward synchronously through the connecting rod 1104 on the right and insert it back into the mounting column 802, so as to realize the quick replacement of the square punch head 1101 and the circular punch head 1102. Then, after loosening the connecting pull rod 1203, the reset spring Ⅰ1202 will push the two blocks 1201 to move backward, and the block 1201 on the left will block and limit the connecting rod 1104 on the left, thereby fixing the square punch head 1101. If the circular punch head 1102 needs to be used to punch the sheet metal, repeat the above steps and then move the tilting rod 1103 clockwise to complete the quick replacement of the punch head.

[0042] When the position of the punch head needs to be adjusted according to the punching requirements, the knob 1301 is turned, and the knob 1301 will drive the threaded rod 1303 to rotate through the bevel gear set 1304, and the threaded rod 1303 will drive the mounting column 802 to move horizontally to the left or right through the thread. During this period, the connecting column 801 can also be driven to rotate by the turning handle 1302, so as to cooperate with the movement of the mounting column 802 to achieve a wider range of adjustment of the punch head, thereby meeting different punching requirements and improving the universality of the device.

[0043] After the selection of the punching head and the adjustment of the punching position are completed, the cylinder 7 is started, and the cylinder 7 will drive the movable platform 5 to move downward along the support column 4 through the connecting block 701. The return spring Ⅰ6 will absorb the vibration generated when the movable platform 5 moves through elasticity, thereby ensuring the stability of the movement of the movable platform 5. Then, as the movable platform 5 moves downward, the pressing block 9 will first contact the sheet metal to be punched, and as the movable platform 5 continues to move downward, the elasticity of the return spring Ⅱ 10 will be used to press the sheet metal downward, so as to limit and fix the sheet metal to be punched, and prevent the sheet metal from shifting or tilting during the punching process. As the connecting block 701 moves downward, the connecting block 701 will drive the two push rods 1501 to move downward synchronously, and the two push blocks 1502 will respectively abut against the connecting plates 1505 on the same side. The connecting plates 1505 will push the inclined surfaces of the corresponding push blocks 1502 to move backward, and the return springs III 1503 will be compressed. Thus, the elasticity of the return springs III 1503 will be utilized to make the corresponding push blocks 1502 pass through the connecting plates 1505 on the same side. When the push blocks 1502 pass through, the return springs III 1503 will be reset to make the corresponding push blocks 1502 pop forward again, and then the corresponding punching heads will punch the sheet metal parts.

[0044] After the punching process of the sheet metal is completed, the cylinder 7 will drive the moving platform 5 to move upward to the initial position through the connecting block 701. During this period, the connecting block 701 will drive the two push rods 1501 to move upward synchronously. At this time, the two push blocks 1502 will move along the inclined surface of the bottom surface of the corresponding connecting plate 1505 along the slide groove 1504 in the direction away from each other. The two connecting plates 1505 will drive the corresponding receiving plates 1401 to move synchronously, and the reset springs II 1403 will be compressed to open the placement slot 3. The sheet metal with the punched holes will fall downward from the placement slot 3. When the two push blocks 1502 pass through the corresponding connecting plates 1505, the reset springs II 1403 will reset the two receiving plates 1401 Move in the direction of approaching each other, thereby reclosing the placement slot 3, and the two receiving plates 1401 will drive the corresponding connecting plates 1505 to move synchronously to the initial position, so as to realize automatic discharging of the sheet metal parts, and the sheet metal parts dropped from the placement slot 3 will fall on the sieve plate 1602 of the collection frame 1601 for unified collection, and the waste generated by punching will pass through the sieve plate 1602 and fall into the chip collection frame 1603 for centralized collection, so as to realize the separation between the punched sheet metal parts and the waste materials, thereby reducing the labor intensity of manual sorting and improving the collection efficiency of sheet metal parts. After the punching process of the sheet metal parts is completed, the collection frame 1601 and the chip collection frame 1603 can be taken out from the front of the support base 1 in turn.
