Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a built-in anti-jamming structure for a die. Background Art

[0002] Stamping dies, also known as cold stamping dies or cold punching dies, are primarily used in the home appliance, electronics, communications, and automotive industries. They utilize dies mounted on a press to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired shape of the part. During the sheet metal stamping process, burrs on the sheet metal can easily cause jamming during transport, forcing processing to be suspended, seriously affecting sheet metal stamping efficiency.

[0003] Chinese patent publication number CN220497514U is a mold with built-in anti-jamming. Through the cleaning component set on one side of the bottom module, the burrs on the bottom of the plate material can be removed during use, thereby effectively avoiding the burrs on the bottom of the plate material causing the plate material to get stuck during the conveying process. At the same time, the rollers set can also reduce the resistance during the conveying of the plate material, making the material conveying smoother.

[0004] Although the burrs on the bottom surface of the plate are removed by the cleaning component in the above patent, there are still burrs on both sides of the plate, which causes the side of the plate to contact the inner side of the limit plate during the conveying process, so the plate will still get stuck.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 4 In an embodiment of the present invention, a mold has a built-in anti-jamming structure, comprising a workbench 1, a support frame 11 being fixedly connected to the top surface of the workbench 1, a lower mold 2 being provided on the top surface of the workbench 1, an upper mold 3 being provided above the lower mold 2, a scraper 23 being fixedly connected to one side surface of the lower mold 2 by bolts, a cleaning mechanism 4 being provided on the lower mold 2 corresponding to the scraper 23, a fixing mechanism 5 being provided between the two sides of the top surface of the lower mold 2, and a slide groove 24 being provided on the top surface of the lower mold 2 near the scraper 23;

[0029] The cleaning mechanism 4 includes a bidirectional screw rod 41, two symmetrical sliders 42, and two symmetrical scrapers 43. The bidirectional screw rod 41 is rotatably connected between the two short side surfaces inside the slide groove 24. The two symmetrical sliders 42 respectively penetrate and screw together at the two ends of the outer wall of the bidirectional screw rod 41. The two symmetrical scrapers 43 are respectively fixedly connected to the opposite side surfaces of the two sliders 42.

[0030] Specifically, first adjust the distance between the two scrapers 43 according to the width of the plate, and then convey the plate through an external conveying device. When the plate is conveyed to the scraper 23, the scraper 23 can clean the burrs on the bottom surface of the plate. When the plate continues to move toward the lower mold 2, the scrapers 43 on both sides of the plate can scrape off the burrs on both sides of the plate, which can prevent the burrs on both sides of the plate from contacting and getting stuck with the fixing mechanism 5, thereby avoiding the plate from getting stuck during the conveying process (although there will be burrs on the top surface of the plate, the top surface of the plate does not contact other objects, so it will not affect the conveying of the plate). When the plate moves into the fixing mechanism 5, the fixing mechanism 5 can limit the plate, which can prevent the upper mold 3 from warping around the stamping area of ​​the plate during the stamping process of the plate, and the stamped finished parts from sliding out from the bottom of the lower mold 2.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, both ends of the bottom surface of the lower mold 2 are fixedly connected to mounting feet 21 fixedly connected to the workbench 1, the bottom surface of the lower mold 2 is fixedly connected to an inclined plate 22, and the top surface of the upper mold 3 is fixedly connected to a hydraulic cylinder 31 fixedly connected to the inner top surface of the support frame 11.

[0033] In this embodiment, the upper die 3 can be moved downward by driving the hydraulic cylinder 31 to punch the plate, and the punched parts slide off the inclined plate 22 .

[0034] Example 2

[0035] like Figure 3 As shown, in this embodiment, four rectangularly distributed fixed blocks 25 are fixedly connected to one side of the lower mold 2, one end of a bidirectional screw rod 41 passes through the side of the lower mold 2 and is fixedly connected to a gear 44, a slide rod 46 is fixedly connected between two fixed blocks 25 at relative positions, a rack 45 meshing with the gear 44 slides through and slides between the two slide rods 46, and both ends of the bottom surface of the rack 45 are fixedly connected to springs 47 fixedly connected to the fixed blocks 25 at corresponding positions.

[0036] In this embodiment, first, the rack 45 is moved downward to disengage it from the gear 44, and then the two sliders 42 can be moved closer to or away from each other by rotating the bidirectional screw rod 1 41. The movement of the slider 42 can drive the scraper 2 43 at the corresponding position to move, so that the distance between the two scrapers 2 43 can be adjusted according to the width of the plate. After the distance between the two scrapers 2 43 is adjusted, the rack 45 is loosened, and the rack 45 is engaged with the gear 44 again under the elastic action of the two springs 47. Therefore, the bidirectional screw rod 1 41 can be prevented from angular deflection during the stamping process, thereby preventing the scraper 2 43 from being separated from the side of the plate.

[0037] Example 3

[0038] like Figure 4 As shown, in this embodiment, the fixing mechanism 5 includes two symmetrical rectangular frames 51 that slide with the top surface of the lower mold 2, and a plurality of round rollers 52 are rotatably connected inside the rectangular frames 51 at equal intervals. L-shaped plates 53 are fixedly connected at both ends of the side surfaces opposite to each other of the two rectangular frames 51, and a rectangular sleeve 54 is slidably sleeved on the outer side of the L-shaped plate 53. A threaded groove is provided at the bottom end of the L-shaped plate 53, and a screw 55 that rotates through the bottom surface of the rectangular sleeve 54 at the corresponding position is screwed in the inside of the threaded groove. A connecting block 56 is fixedly connected to one side of the rectangular sleeve 54, and a bidirectional screw rod 57 rotatably passed through the lower mold 2 through a bearing is screwed between the two connecting blocks 56 at relative positions, and both ends of the bidirectional screw rod 57 are fixedly connected to a rotating block.

[0039] In this embodiment, first, according to the width of the plate, the two rectangular frames 51 can be moved away from or closer to each other by simultaneously rotating the two bidirectional screw rods 57. When the two sides of the plate are respectively located under the multiple round rollers 52 at the corresponding positions, the two screw rods 55 on the same side can be rotated at the same time. The rotating screw rods 55 can move the L-shaped plates 53 at the corresponding positions. The movement of the two L-shaped plates 53 on the same side can drive the rectangular frames 51 at the corresponding positions to move, so that the plate can be pressed between the multiple round rollers 52 and the lower mold 2, which can prevent the periphery of the plate stamping area from warping during the stamping process of the upper mold 3.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
