Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically, it relates to an adjustable multi-angle sheet metal stamping die. Background Technology

[0002] In the field of sheet metal stamping, quick die changes and multi-angle stamping are key to improving production efficiency and adapting to diverse processing needs.

[0003] Traditional stamping dies typically employ a fixed structure, requiring machine shutdown and manual removal of bolts or clamps when changing dies. This process is cumbersome and time-consuming, severely impacting production efficiency. Furthermore, while some automated die-changing systems can achieve rapid switching, they are complex in structure, costly, and difficult to adapt to the flexible adjustment needs of dies of different sizes.

[0004] To address the aforementioned issues, this application proposes an adjustable multi-angle sheet metal stamping die. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an adjustable multi-angle sheet metal stamping die to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable multi-angle sheet metal stamping die includes an operating table. A stamping head is fixedly installed on the top of the operating table, and a stamping strip is installed on the stamping head. Two symmetrically arranged fixed seats are fixedly installed at the bottom of the operating table. The same feeding roller is rotatably connected between the two fixed seats, and multiple die bodies are provided on the feeding roller.

[0008] The top pressing and fixing mechanism includes a positioning plate, which is rotatably mounted on the left side of the feeding roller. Multiple concave plates are fixedly mounted on the positioning plate, and the concave plates cooperate with the corresponding mold body.

[0009] A one-way mold changing mechanism includes a turntable, which is fixedly installed on the right side of the feeding roller. A drive cylinder is rotatably connected to the bottom of the operating table, and the piston of the drive cylinder is connected to the turntable for transmission.

[0010] Preferably, the feeding roller has multiple slots, and the mold body is slidably installed in the corresponding slots.

[0011] The sliding connection between the slot and the mold body allows for vertical positioning of the mold body and facilitates horizontal sliding of the mold body, making installation and disassembly easier, as well as facilitating the rotation of the feeding roller for material feeding.

[0012] Preferably, the top-pressing fixing mechanism includes a top pin, which is threadedly connected to a concave plate. One end of the top pin is rotatably connected to a pressure plate, which is slidably installed on the inner wall of the corresponding slot.

[0013] The top pin is threadedly connected to the concave plate, and the pressure plate is slidably installed on the inner wall of the slot, so that the rotating top pin can drive the pressure plate to press and fix the mold body.

[0014] Preferably, the one-way mold changing mechanism includes a ratchet, which is fixedly installed on the feeding roller. A locking pin is rotatably connected to the bottom of the operating table. The locking pin engages with the ratchet, and a tension spring is fixedly installed on the top of the locking pin. The top of the tension spring is fixedly connected to the bottom of the operating table.

[0015] The ratchet and the locking pin engage to push the ratchet, allowing the feed roller to rotate in only one direction. The tension spring also helps to limit the position of the locking pin, thus maintaining the locking effect.

[0016] Preferably, one side of the turntable has multiple L-shaped grooves corresponding to the number of slots, and the multiple L-shaped grooves are connected end to end. A movable shaft is fixedly installed on the piston of the drive cylinder, and the movable shaft is slidably connected to the inner wall of the L-shaped groove.

[0017] The piston of the drive cylinder drives the movable shaft to move. The movable shaft is slidably connected to the L-shaped slide groove. When the movable shaft is at the bend of the L-shaped slide groove, it can push the turntable to rotate. When the piston of the drive cylinder drives the movable shaft to retract, it moves to the next bend through the L-shaped slide groove, thus facilitating the next push.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] Multiple slots are provided on the feeding roller, allowing the mold body to slide laterally. This enables quick mold replacement without the need for complex disassembly tools, significantly improving mold changing efficiency. By rotating the positioning plate, the concave plate is misaligned with the slots, allowing the mold body to be pulled out laterally, simplifying the disassembly process.

[0020] The ratchet and spring-loaded locking pins work together to ensure that the feeding roller can only rotate in one direction, avoiding rebound error and maintaining station stability. The drive cylinder slides in the L-shaped grooves connected end to end through the movable shaft. After each stroke, it pushes the turntable to rotate at a fixed angle (matching the number of grooves), thus achieving precise indexing and switching of the mold. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-5 An adjustable multi-angle sheet metal stamping die includes an operating table 1. A stamping head 2 is fixedly installed on the top of the operating table 1. A stamping strip 3 is installed on the stamping head 2. Two symmetrically arranged fixed seats 4 are fixedly installed at the bottom of the operating table 1. The same feeding roller 5 is rotatably connected between the two fixed seats 4. Multiple die bodies 6 are provided on the feeding roller 5.

[0030] The top pressing and fixing mechanism 7 includes a positioning plate 71, which is rotatably mounted on the left side of the feeding roller 5. Multiple concave plates 72 are fixedly mounted on the positioning plate 71, and the concave plates 72 cooperate with the corresponding mold body 6.

[0031] The one-way mold changing mechanism 8 includes a turntable 81, which is fixedly installed on the right side of the feeding roller 5. A drive cylinder 83 is rotatably connected to the bottom of the operating table 1, and the piston of the drive cylinder 83 is connected to the turntable 81 in a transmission connection.

[0032] Reference Figure 3 and Figure 4 The feeding roller 5 has multiple slots 9, and the mold body 6 is slidably installed in the corresponding slots 9. Through the sliding connection between the slots 9 and the mold body 6, the mold body 6 can be limited vertically and horizontally, and can be easily slid horizontally to the left and right, thus facilitating installation and disassembly, and also facilitating the rotation of the feeding roller 5 for feeding.

[0033] Reference Figure 4 The top-pressing fixing mechanism 7 includes a top pin 73, which is threadedly connected to the concave plate 72. One end of the top pin 73 is rotatably connected to a pressure plate 74, which is slidably installed on the inner wall of the corresponding slot 9. Through the threaded connection between the top pin 73 and the concave plate 72, and the slidable installation of the pressure plate 74 on the inner wall of the slot 9, the rotating top pin 73 can drive the pressure plate 74 to press and fix the mold body 6.

[0034] Reference Figure 5 The one-way mold changing mechanism 8 includes a ratchet 87, which is fixedly mounted on the feeding roller 5. A locking pin 85 is rotatably connected to the bottom of the operating table 1. The locking pin 85 engages with the ratchet 87, and a tension spring 86 is fixedly mounted on the top of the locking pin 85. The top of the tension spring 86 is fixedly connected to the bottom of the operating table 1. A plurality of L-shaped grooves 84 corresponding to the number of slots 9 are opened on one side of the turntable 81, and the plurality of L-shaped grooves 84 are connected end to end. A movable shaft 82 is fixedly mounted on the piston of the drive cylinder 83. The movable shaft 82 is slidably connected to the inner wall of the L-shaped groove 84, and the locking pin 85 engages with the ratchet 87. This allows the ratchet 87 to be engaged and pushed, ensuring that the feeding roller 5 can only rotate in one direction under the action of the ratchet 87. At the same time, the tension spring 86 can easily limit the position of the locking pin 85, thus maintaining the engagement effect. The piston of the drive cylinder 83 drives the movable shaft 82 to move. The movable shaft 82 is slidably connected to the L-shaped slide groove 84. When the movable shaft 82 is at the bend of the L-shaped slide groove 84, it can push the turntable 81 to rotate. When the piston of the drive cylinder 83 drives the movable shaft 82 to retract, it moves to the next bend through the L-shaped slide groove 84, thus facilitating the next push.

[0035] Working principle: During operation, the sheet metal is placed on the operating table 1, and mold bodies 6 of different sizes are clamped in the slots 9. The stamping head 2 drives the stamping strip 3 to move downwards and stamp the sheet metal on the mold body 6. When it is necessary to change the mold body 6, the drive cylinder 83 switch is activated. The piston of the drive cylinder 83 drives the movable shaft 82 to move. The movable shaft 82 is slidably connected to the L-shaped slide 84. When the movable shaft 82 is at the bend of the L-shaped slide 84, it can push the turntable 81 to rotate. When the piston of the drive cylinder 83 drives the movable shaft... When 82 retracts, it moves to the next bend through the L-shaped slide 84, making it easier to push next time. At the same time, it is connected to the concave plate 72 by the threaded connection of the top pin 73 and the pressure plate 74 is slidably installed on the inner wall of the slot 9, so that the rotating top pin 73 can drive the pressure plate 74 to press and fix the mold body 6. When it is necessary to disassemble the mold body 6, the pressure plate 74 is moved out of the slot 9, and the positioning plate 71 is rotated, so that the positioning plate 71 drives the concave plate 72 to rotate to a position that is misaligned with the slot 9, so that the mold body 6 in the slot 9 can be slid out.
