Anti-theft hook stamping device

Abstract

According to the anti-theft hook stamping device, a to-be-stamped plate is placed on the lower blanking die, and stamping equipment drives the upper blanking die to move close to the lower blanking die through the upper bearing table. And each blanking block is correspondingly inserted into the corresponding blanking groove, and the product is blanked into the blanking grooves. In the process, the blanking block is combined with the blanked product to push the pop-up plate to slide downwards along the blanking groove, the pop-up plate drives the sliding rod to slide downwards along the sliding hole, the sliding rod drives the compression plate to slide downwards along the elastic cavity, and the compression plate extrudes the first compression spring in the process of sliding downwards. When the stamping equipment drives the blanking upper die to move away from the blanking lower die through the upper bearing table, the first compression spring recovers the elastic deformation and drives the pop-up plate to slide upwards along the blanking groove through the compression plate and the sliding rod, so that the product in the blanking groove is pushed out of the blanking groove, and the blanked product can be taken down from the blanking lower die conveniently.

[0027] During the operation of the above anti-theft hook stamping device 10, the to-be-stamped sheet is placed on the blanking lower die 500, and the stamping equipment 100 drives the blanking upper die 300 to move closer to the blanking lower die 500 through the upper receiving table 200. So that each blanking block 310 is correspondingly inserted into a blanking groove 501, and the product is blanked into the blanking groove 501. During this process, the blanking block 310 combines with the blanked product to push the ejector plate 610 to slide downward along the blanking groove 501. The ejector plate 610 drives the sliding rod 620 to slide downward along the sliding hole 503, and the sliding rod 620 drives the compression plate 630 to slide downward along the elastic cavity 502. During the downward sliding of the compression plate 630, the first compression spring 640 is squeezed. When the stamping equipment 100 drives the blanking upper die 300 to move away from the blanking lower die 500 through the upper receiving table 200, the first compression spring 640 restores its elastic deformation and drives the ejector plate 610 to slide upward along the blanking groove 501 through the compression plate 630 and the sliding rod 620, so as to push the product in the blanking groove 501 out of the blanking groove 501, so as to facilitate removing the blanked product from the blanking lower die 500. After the above anti-theft hook stamping device 10 stamps and cuts the sheet, it avoids the cut-out parts being embedded in the blanking lower die 500, ensuring the processing and production efficiency.

[0028] In order to fix the to-be-blanked sheet and thus increase the working stability of the anti-theft hook stamping device 10, in one embodiment, please refer to Figure 1 and Figure 4, the anti-theft hook stamping device 10 further includes two fixing mechanisms 700. The two fixing mechanisms 700 are arranged perpendicular to each other in an L shape on the lower receiving table 400, and the two fixing mechanisms 700 are arranged at a corner of the blanking lower die 500. The fixing mechanism 700 includes an L-shaped clamping plate 710 and a plurality of fixing components 720. One end of the L-shaped clamping plate 710 is connected to the lower receiving table 400, and a plurality of elastic grooves 701 are evenly formed on the inner wall of the other end of the L-shaped clamping plate 710. Each fixing component 720 is correspondingly arranged in an elastic groove 701. The fixing component 720 includes a second compression spring 721 and a fixing pressing block 722. The second compression spring 721 is arranged in the elastic groove 701. One end of the second compression spring 721 is connected to the bottom of the elastic groove 701, and the other end of the second compression spring 721 is connected to the fixing pressing block 722. The fixing pressing block 722 is adapted to the elastic groove 701. The fixing pressing block 722 is partially inserted into the elastic groove 701 and is slidably connected to the L-shaped clamping plate 710. A driving inclined surface is arranged at the corner of the end of the fixing pressing block 722 exposed outside the L-shaped clamping plate 710. During the process of placing the plate, the two sides of the plate are inserted into the two L-shaped clamping plates 710. During this process, the plate to be blanked drives each fixing pressing block 722 to slide upward along each elastic groove 701 respectively through each driving inclined surface, so as to squeeze each second compression spring 721. When the plate to be blanked abuts against the inner wall of one side of the L-shaped clamping plate 710, each second compression spring 721 squeezes and fixes the plate to be blanked through each fixing pressing block 722. In this way, the two fixing mechanisms 700 can fix the plate to be blanked, thereby increasing the working stability of the anti-theft hook stamping device 10.

[0029] In one embodiment, please refer to Figure 1 and Figure 3, in order to prevent the residual material generated during the blanking process from sticking to the blanking upper die 300, the anti-theft hook stamping device 10 further includes a plurality of anti-sticking mechanisms 800, and each anti-sticking mechanism 800 is uniformly arranged on the blanking upper die 300. Each anti-sticking mechanism 800 includes a pop-up rod 810, a sliding plate 820, a sliding rod 830, and a third compression spring 840. One end of the pop-up rod 810 is connected to the middle area of the sliding plate 820, and one end of the sliding rod 830 is connected to the middle area of the sliding plate 820 facing away from the end of the pop-up rod 810. A plurality of pop-up chutes 301 are uniformly formed on the surface of the blanking upper die 300 facing the blanking lower die 500. A pop-up sliding cavity 302 is formed at the bottom of the pop-up chute 301, and a pop-up slideway 303 is formed at the bottom of the pop-up sliding cavity 302. The width of the pop-up sliding cavity 302 is greater than the width of the pop-up chute 301 and the width of the pop-up slideway 303. The pop-up rod 810 is adapted to the pop-up chute 301, and a part of the pop-up rod 810 is inserted into the pop-up chute 301 and is slidably connected to the blanking upper die 300. A part of the pop-up rod 810 is exposed outside the pop-up chute 301. The sliding plate 820 is adapted to the pop-up sliding cavity 302, and the sliding plate 820 is inserted into the pop-up sliding cavity 302 and is slidably connected to the blanking upper die 300. The sliding rod 830 is adapted to the pop-up slideway 303, and the sliding rod 830 is inserted into the pop-up slideway 303 and is slidably connected to the blanking upper die 300. The third compression spring 840 is received in the pop-up sliding cavity 302. One end of the third compression spring 840 is connected to the sliding plate 820, and the other end of the third compression spring 840 is connected to the inner wall of the pop-up sliding cavity 302 near one end of the pop-up slideway 303. During the blanking operation of the anti-theft hook stamping device 10, the stamping equipment 100 drives the blanking upper die 300 to move close to the blanking lower die 500 through the upper bearing table 200, so that the pop-up rod 810 moves upward along the pop-up chute 301. The pop-up rod 810 drives the sliding plate 820 to move upward along the pop-up sliding cavity 302. During the process of the sliding plate 820 moving upward along the pop-up sliding cavity 302, the third compression spring 840 is squeezed, and the sliding rod 830 is driven to move upward along the pop-up slideway 303. After the blanking of the anti-theft hook stamping device 10 is completed, when the stamping equipment 100 drives the blanking upper die 300 to move away from the blanking lower die 500 through the upper bearing table 200, the third compression spring 840 recovers its elastic deformation, and drives the pop-up rod 810 to move downward along the pop-up sliding cavity 302 through the sliding plate 820, so as to eject the residual material sticking to the blanking upper die 300. In this way, each anti-sticking mechanism 800 can effectively prevent the residual material generated during the blanking process from sticking to the blanking upper die 300.
