Description

Technical Field

[0001] This utility model belongs to the technical field of stamping auxiliary devices, specifically relating to a stripping device for stamping dies. Background Technology

[0002] In the field of metal sheet stamping, 90-degree bending is a common process, widely used in the production of automotive parts, electrical housings, hardware accessories and other products. In this process, the stripping device is a key component to ensure continuous production. Currently, to facilitate stripping, a cylinder is installed on the side of the lower module. The cylinder piston rod is directly connected to the push rod. After the workpiece is bent, the cylinder piston rod extends and drives the push rod to move toward the workpiece, pushing the workpiece off the lower module.

[0003] However, during the process of ejecting the metal plate, the ejector rod needs to penetrate the mold. This requires the installation of a cylinder with a large stroke, which not only takes up a lot of space, but also results in relatively large losses due to the large stroke. In addition, the position of a typical ejector device is fixed after installation, making it inconvenient to adjust according to different mold sizes, thus resulting in poor applicability. Utility Model Content

[0004] The purpose of this invention is to provide a stripping device for stamping dies to solve the above problems. Stripping can be completed by a cylinder with a small stroke, which reduces space occupation and energy consumption. At the same time, it is convenient to flexibly adjust the position of the stop block according to the die size, thereby effectively improving applicability.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a stripping device for stamping dies, comprising a base, a slider slidably connected to the base, a connecting seat fixedly connected to the slider, a slide plate slidably connected to the connecting seat, a stripping structure provided on the slide plate, the stripping structure including a slide rod and a stop block, a slide rod slidably connected to the slide plate, a stop block detachably installed at one end of the slide rod, a cut surface provided on the slide rod, a plurality of tooth grooves provided on the slide rod, a cylinder installed on the slide plate, a connecting plate fixedly connected to the output end of the cylinder, a gear rotatably connected to the connecting plate, a rack fixedly connected to the slide plate, one side of the gear meshing with the tooth groove, and the other side of the gear meshing with the rack.

[0006] In a preferred embodiment, the base and the connecting seat are perpendicular, the connecting seat and the slide plate are perpendicular, the slide plate and the base are parallel, and the slide plate and the slide rod are perpendicular.

[0007] As a preferred embodiment, a fixing bolt is provided through the abutment block, and the fixing bolt is threadedly connected to one end of the slide rod.

[0008] As a preferred embodiment, the base is fixedly connected with a plurality of connecting pieces, and the connecting pieces are provided with mounting holes.

[0009] In a preferred embodiment, a first lead screw is rotatably connected to the base, and the first lead screw is threadedly connected to the slider.

[0010] As a preferred embodiment, one end of the first lead screw is fixedly connected to a first knob, and the outer side of the first knob has multiple anti-slip grooves arranged in a circumferential array.

[0011] As a preferred embodiment, a second lead screw is rotatably connected to the connecting seat, and the second lead screw is threadedly connected to the slide plate.

[0012] As a preferred embodiment, one end of the second lead screw is fixedly connected to a second knob, and the outer side of the second knob has multiple anti-slip grooves arranged in a circumferential array.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In use, this invention utilizes a cylinder. The extended output end of the cylinder moves the connecting plate, which in turn moves the gear. During this movement, the gear causes a sliding rod to slide on the slide plate. A slit is designed to prevent the sliding rod from rotating, ensuring the gear remains engaged with the tooth groove. Because the gear meshes with the rack, it rotates as it moves, which in turn moves the sliding rod on the slide plate. Therefore, when the cylinder extends a short distance, the sliding rod can slide a long distance. Even with a small stroke, the sliding rod can travel a significant distance to penetrate the lower module. As the sliding rod penetrates the lower module, the abutment pushes the workpiece off. Thus, even with a small stroke, workpiece removal is achieved, reducing space occupation and wear. Furthermore, the position of the abutment can be adjusted by sliding the slider on the base, and its position can be adjusted by sliding the slide plate on the connecting seat. This allows for adjustments to the abutment's position when dealing with molds of different sizes, improving its applicability. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 4 As shown, this utility model embodiment provides a stripping device for stamping dies, including a base 1, a slider 2 slidably connected to the base 1, a connecting seat 3 fixedly connected to the slider 2, a slide plate 4 slidably connected to the connecting seat 3, and a stripping structure 5 provided on the slide plate 4. The stripping structure 5 includes a slide rod 501 and a stop block 502. The slide rod 501 is slidably connected to the slide plate 4, and the stop block 502 is detachably installed at one end of the slide rod 501. The slide rod 501 has a cut surface 503 and multiple teeth. A cylinder 508 is installed on the slot 504 and the slide plate 4. A connecting plate 507 is fixedly connected to the output end of the cylinder 508. A gear 505 is rotatably connected to the connecting plate 507. A rack 506 is fixedly connected to the slide plate 4. One side of the gear 505 meshes with the slot 504, and the other side of the gear 505 meshes with the rack 506. The base 1 is perpendicular to the connecting seat 3, the connecting seat 3 is perpendicular to the slide plate 4, the slide plate 4 is parallel to the base 1, and the slide plate 4 is perpendicular to the slide rod 501.

[0018] In this embodiment, during use, activating cylinder 508 extends its output end, causing connecting plate 507 to move. Connecting plate 507 then drives gear 505 to move. During its movement, gear 505 causes slide rod 501 to slide on slide plate 4. By setting the tangential surface 503, rotation of slide rod 501 is prevented, ensuring that gear 505 is always engaged with tooth groove 504. Since gear 505 is engaged with rack 506, it rotates as it moves. This rotation of gear 505, in turn, drives slide rod 501 to move on slide plate 4. Therefore, when cylinder 508 extends a small distance, slide rod 501 can slide a large distance. Thus, even with a small stroke, cylinder 508 can achieve this. The slide bar 501 travels a considerable distance to penetrate the lower module. During this process, the abutment block 502 pushes the workpiece off the lower module. Therefore, the workpiece can also be removed by the short-stroke cylinder 508, which not only reduces space occupation but also reduces wear. The first screw 7 can be rotated by holding the first knob 6, which drives the slider 2 to slide on the base 1. Thus, the position of the abutment block 502 can be adjusted. The second screw 9 can be rotated by holding the second knob 8, which drives the slide plate 4 to slide on the connecting seat 3. Thus, the position of the abutment block 502 can be adjusted vertically. Therefore, the position of the abutment block 502 can be adjusted accordingly when dealing with molds of different sizes.

[0019] Please see Figures 1 to 4 As shown, a fixing bolt 12 is provided through the abutment 502. The fixing bolt 12 can be used to install the abutment 502 at the end of the slide rod 501. At the same time, the fixing bolt 12 can be unscrewed to disassemble the abutment 502, so that the abutment 502 can be replaced individually when it is damaged. The fixing bolt 12 is threadedly connected to one end of the slide rod 501. Multiple connecting pieces 10 are fixedly connected to the base 1. The connecting pieces 10 have mounting holes 11, so that the base 1 can be easily installed and fixed.

[0020] Please see Figures 1 to 4As shown, a first lead screw 7 is rotatably connected to the base 1, and the first lead screw 7 is threadedly connected to the slider 2. Rotating the first lead screw 7 allows for precise and rapid adjustment of the slider 2's position. A first knob 6 is fixedly connected to one end of the first lead screw 7. Multiple anti-slip grooves are arranged in a circumferential array on the outer side of the first knob 6, allowing for easy rotation of the first lead screw 7 by holding the first knob 6. A second lead screw 9 is rotatably connected to the connecting seat 3, and the second lead screw 9 is threadedly connected to the slide plate 4. Rotating the second lead screw 9 allows for quick and precise adjustment of the slide plate 4's position. A second knob 8 is fixedly connected to one end of the second lead screw 9. Multiple anti-slip grooves are arranged in a circumferential array on the outer side of the second knob 8, allowing for easy rotation of the second lead screw 9 by holding the second knob 8.
