[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1 to Figure 4 and Figure 8In an embodiment of the present invention, a stamping device for a compression pump housing includes an upper die 2 and a lower die 1, wherein a punch 201 is provided at the bottom of the upper die 2, a plate placing groove 102 is provided at the top of the lower die 1, a die groove 101 is provided in the middle of the plate placing groove 102, and the punch 201 is matched with the die groove 101, a plurality of longitudinal slide grooves 203 are provided on the upper die 2, a first plugging component 4 is provided at the bottom of the longitudinal slide groove 203, a punching component 3 is provided in the longitudinal slide groove 203, a plurality of blanking holes 103 are provided on the lower die 1, the blanking holes 103 are located directly below the longitudinal slide groove 203, and a second plugging component is provided on the top of the blanking holes 103.

[0024] During specific use, the metal sheet is placed in the plate placing groove 102, and the connecting cylinder 10 is driven to move downward by the hydraulic cylinder on the punching machine.

There are two mounting frames 5, and both mounting frames 5 are provided with an oil delivery assembly 7, the oil delivery assembly 7 includes a second cylinder 71, the second cylinder 71 is fixedly mounted on the top of the mounting frame 5, a second infusion port 73 is provided on one side of the second cylinder 71, a shunt pipe 6 is provided on one side of the second infusion port 73, and the shunt pipe 6 is connected to the first infusion port 45, a second piston 72 is slidably mounted in the second cylinder 71, a screw rod 74 is rotatably mounted on one side of the second piston 72, a nut 75 is fixedly mounted on one side of the second cylinder 71, the screw rod 74 penetrates the nut 75, and the screw rod 74 is threadedly connected to the nut 75, one end of the screw rod 74 is fixedly connected to an adjusting column 76, and a driving assembly 8 for driving the adjusting column 76 to rotate is provided on one side of the adjusting column 76, and the first cylinder 42 and the second cylinder 71 are both filled with oil; The driving assembly 8 includes a supporting plate 81, which is fixedly mounted on the top of the upper mold 2. A driving cylinder 82 is rotatably mounted on the supporting plate 81. One end of the adjusting column 76 passes through the driving cylinder 82. A limiting groove 761 is provided on the adjusting column 76. The adjusting column 76 slidably cooperates with the driving cylinder 82. The setting of the limiting groove 761 enables the adjusting column 76 to slide relative to the driving cylinder 82 but cannot rotate relative to the driving cylinder 82.

The radius of the second gear 85 is greater than the radius of the first gear 83, thereby playing a speed regulating role, so that the adjusting column 76 can rotate a sufficient number of circles.

[0027] When the connecting plate 15 moves downward, the connecting plate 15 drives the rack 87 to move downward, and the rack 87 drives the third gear 86 to rotate when it moves downward. When the third gear 86 rotates, it drives the second gear 85 to rotate through the connecting shaft 84.

When the driving cylinder 82 rotates, it drives the adjusting column 76 to rotate through the limiting groove 761. When the adjusting column 76 rotates, it drives the screw 74 to rotate. Under the action of the nut 75, the screw 74 can drive the second piston 72 to move in the direction away from the second infusion port 73 when it rotates, so that the oil in the first cylinder 42 is pumped into the second cylinder 71 through the shunt pipe 6, so that the first plug rod 43 moves upward, so that the blocking block 41 releases the bottom of the longitudinal slide groove 203. The sealing allows the punching head 32 in the longitudinal slide groove 203 to extend from the bottom opening of the longitudinal slide groove 203; when the connecting plate 15 just starts to move downward, it can automatically drive the blocking block 41 to move upward at an angle to automatically open the bottom opening of the longitudinal slide groove 203. After the bottom opening of the longitudinal slide groove 203 is fully opened, the push plate 16 begins to contact the push plate 35, thereby driving the punching head 32 to move downward for punching, so that the downward movement of the connecting plate 15 can not only drive the first blocking component 4 to open, but also drive the punching head 32 to perform the punching operation, thereby effectively improving the synchronization; through the setting of the screw 74, the second piston 72 can be self-locking, so that during the stamping process, the blocking block 41 will not move when it is in contact with the metal plate and is under pressure, thereby ensuring the accuracy of the stamping process.

[0028] See also Figure 2 , Fig. 9 and Fig.10In the embodiment of the present invention, the second blocking component includes a blocking plate 19, a connecting block 20 and a tension spring 21. A plurality of slots 104 are provided on the top of the lower die 1. The slots 104 are communicated with the tops of the blanking holes 103. The blocking plate 19 is slidably installed in the slots 104. One end of the blocking plate 19 extends out of the slot 104, and a connecting block 20 is fixedly installed on the end of the blocking plate 19. A tension spring 21 is fixedly connected to one side of the connecting block 20. The connecting block 20 is elastically connected to the outer wall of the lower die 1 through the tension spring 21. A connecting frame 17 is fixedly installed on one side of the push plate 16. The connecting frame 17 is L-shaped. A magnetic element 18 is fixedly installed on the bottom end of the connecting frame 17. The magnetic element Part 18 is a magnet, an electromagnet, etc., and the connecting block 20 is made of iron material; when the upper mold 2 and the lower mold 1 are completely closed, as the push plate 16 moves downward, the push plate 16 drives the magnetic element to move downward through the connecting frame 17, so that the magnetic element 18 moves to one side of the connecting block 20, so that the magnetic element 18 and the connecting block 20 are magnetically attracted, so that the connecting block 20 drives the sealing plate 19 to move, so that the sealing plate 19 slides in the slot 104, so that the top opening of the blanking hole 103 is opened, and then the waste generated by the subsequent punching can enter the blanking hole 103 and be discharged, and the second sealing component can be automatically opened after the stamping is completed and before the punching head 32 moves downward, and the synchronization is good.

[0029] Working principle: Place the metal sheet in the plate placing groove 102, and drive the connecting cylinder 10 to move downward through the hydraulic cylinder on the punching machine. At this time, the locking component locks the connecting column 9, thereby driving the upper mold 2 to move downward for mold closing through the connecting column 9, and extrude the metal sheet through the punch 201 in cooperation with the die groove 101. After the molding is completed, release the lock of the locking component on the connecting column 9, and continue to drive the connecting cylinder 10 to move downward, so that the connecting cylinder 10 moves downward relative to the connecting column 9, and compress the second spring 12. When the connecting cylinder 10 moves downward, it drives multiple push plates 16 to move downward through the connecting plate 15. When the connecting plate 15 moves downward, the connecting plate 15 drives the rack 87 to move downward. When the rack 87 moves downward, it drives the third gear 86 to rotate. When the third gear 86 rotates, it drives the second gear 85 to rotate through the connecting shaft 84. When the second gear 85 rotates, it drives the first gear 83 to rotate, thereby driving the driving cylinder 82 to rotate. When the driving cylinder 82 rotates, it drives the adjusting column 76 to rotate through the limiting groove 761. When the adjusting column 76 rotates, it drives the screw 74 to rotate. Under the action of the nut 75, when the screw 74 rotates, it can drive the second piston 72 to move in a direction away from the second infusion port 73, so that the oil in the first cylinder 42 is drawn into the second cylinder 71 through the shunt pipe 6, so that the first plug rod 43 moves upward, so that the blocking block 41 releases the blocking of the bottom of the longitudinal slide groove 203, so that the punching head 32 in the longitudinal slide groove 203 can extend from the bottom opening of the longitudinal slide groove 203; Further, when the upper mold 2 and the lower mold 1 are completely closed, as the push plate 16 moves downward, the push plate 16 drives the magnetic element to move downward through the connecting frame 17, so that the magnetic element 18 moves to one side of the connecting block 20, so that the magnetic element 18 and the connecting block 20 are magnetically attracted to each other, so that the connecting block 20 drives the blocking plate 19 to move, so that the blocking plate 19 slides in the slot 104, so that the top opening of the blanking hole 103 is opened; Subsequently, the push plate 16 contacts the push plate 35. As the push plate 16 continues to move downward, the push plate 35 overcomes the elastic force of the first spring 34 and pushes the top column 31 downward, thereby driving the punching head 32 to move downward. The punching head 32 extends from the bottom opening of the longitudinal slide groove 203, thereby punching the formed compression pump housing. The waste punched out by the punching head 32 is discharged through the blanking hole 103 on the lower mold 1, and the waste is collected by setting a waste collection box under the lower mold 1.
