[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] The utility model provides Figures 1 to 3 The illustrated sealing strip punching and forming tool includes a base 1. Two horizontal slots 16 are cut into the top of the base 1. These slots 16 are parallel to each other and face upward. A slider 12 fits within each slot 16. The tops of the two sliders 12 are welded to a horizontal support plate 10. A handle 11 is welded to the support plate 10 for easy removal.

[0024] A placement groove 13 is chiseled on the top of the placement plate 10. The notch of the placement groove 13 faces upward and the automobile sealing strip to be cut is placed inside. The automobile sealing strip is clamped to the placement groove 13 and its length direction is perpendicular to the sliding direction of the placement plate 10. It is used to limit the position of the automobile sealing strip.

[0025] Several vertical guide rods 8 are welded to the top of the base 1 and arranged in a matrix. A horizontal mounting plate 4 is placed horizontally above the base 1, slidingly engaging all guide rods 8. A linkage is installed between the mounting plate 4 and the placement plate 10, so that the horizontal sliding of the placement plate 10 drives the mounting plate 4 up and down synchronously.

[0026] The linkage assembly includes a screw 3, a gear 9, and a rack 15. The screw 3 is arranged vertically and is rotatably connected to the base 1. The screw 3 passes through the mounting plate 4 and is threadedly connected to it. Fixed stop caps are welded to the tops of the screw 3 and several guide rods 8 to prevent the mounting plate 4 from dislodging upward from the screw 3 and guide rods 8.

[0027] The rack 15 is arranged along the sliding direction of the placement plate 10 and is fixedly connected to the placement plate 10. The gear 9 is coaxially fixedly connected to the screw rod 3, and the rack 15 is meshed with the gear 9.

[0028] Multiple cutters 5 are welded to the bottom of the mounting plate 4. These cutters 5 are parallel to each other and arranged in a straight line along the length of the automotive sealing strip. Each cutter 5 has three cutting edges, one of which points vertically downward toward the base 1. The other two cutting edges are located at the front and rear of the cutter 5 along the sliding direction of the mounting plate 10.

[0029] Multiple punched grooves 14 are chiseled into the placement plate 10 along its sliding direction. Each punched groove 14 faces vertically upward and communicates with the placement groove 13. Each punched groove 14 extends through the placement plate 10 along its sliding direction. Each punched groove 14 corresponds to a plurality of cutters 5. Each cutter 5 slides downwardly into its corresponding punched groove 14, simultaneously cutting the automotive sealing strip.

[0030] A baffle 6 is placed horizontally between the placement plate 10 and the mounting plate 4. Baffle 6 is fixedly connected to the base 1 via a connecting plate. Multiple vertical slots 7 are chiseled into baffle 6. These slots 7 correspond to the cutters 5, with each cutter 5 sliding through its corresponding slot 7. Baffle 6 is used to remove automotive sealing strips that adhere to the cutters 5.

[0031] A receiving groove 2 is chiseled in the base 1 , with the notch of the receiving groove 2 facing upward and located just below the baffle 6 , for receiving the automobile sealing strip that falls off the cutter 5 .

[0032] Working Principle: To use, place the automotive sealing strip to be cut into the placement slot 13. Then, push the handle 11, which slides the placement plate 10 toward the bottom of the cutter 5. This moves the automotive sealing strip toward the bottom of the cutter 5. During this process, the placement plate 10 moves the rack 15 synchronously, which in turn rotates the gear 9. This gear 9 rotates the screw 3, which pushes the mounting plate 4 downward, which in turn moves the cutter 5 downward.

[0033] When the cutter 5 moves downward, it slides through the corresponding through slot 7 on the baffle 6 and gradually slides into the corresponding punching slot 14 on the placement plate 10 .

[0034] As the cutter 5 slides into the corresponding punched slot 14, it first contacts the automotive sealing strip. Then, as the placement plate 10 continues to move, the cutter 5 continues to move downward and slides horizontally forward relative to the placement plate 10. At this point, the cutter 5 cuts the automotive sealing strip. When the placement plate 10 moves directly below the cutter 5, the automotive sealing strip is completely severed.

[0035] Then, handle 11 is pulled in the opposite direction, causing the placement plate 10 to slide horizontally away from the cutter 5. At this point, rack 15 pushes gear 9 in reverse, which in turn drives screw 3 in reverse. Screw 3 pushes mounting plate 4 upward, which in turn drives cutter 5 upward. During this process, cutter 5 slides horizontally backward relative to placement plate 10.

[0036] Thereafter, the cutter 5 slides upward out of the corresponding punching slot 14 and gradually out of the corresponding through-groove 7. During this process, the automotive sealing strip adhered to the cutter 5 is pushed off by the baffle 6 and falls into the receiving slot 2. When the placement plate 10 slides to its initial position, the cut automotive sealing strip is removed from the placement plate 10. Simultaneously, the placement plate 10 fully opens the receiving slot 2, allowing the cut automotive sealing strip to be removed from the receiving slot 2.

[0037] During the sliding process of the placement plate 10 , the slider 12 does not escape from the sliding groove 16 .

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
