Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a continuous stamping die template connection mechanism. Background Technology

[0002] Blanking is an indispensable process in stamping production, and a good stamping die structure is a reliable guarantee for realizing the process plan. The quality and precision of the stamped workpiece mainly depend on the quality and precision of the die edge and die cavity. The stamping die structure needs to be reasonable, and the materials used for the stamping die also need to be reasonable. The rationality of the stamping die structure and the quality of the materials used directly affect the production efficiency, the service life of the stamping die itself, and the safety and convenience of operation. In continuous stamping dies, the lower die pulls the strip in the middle, and the upper die presses down to achieve continuous stamping. However, for some long stamping dies, when using a single die cavity, excessive length can cause die cavity deformation. Usually, multiple die plates are used to achieve this, and a quick-connect structure for the die plates needs to be designed to achieve stable connection of the die plates. However, traditional pusher mechanisms are mostly triggered by mechanical cams or limit switches. Machining errors in the cam profile or wear of the switch contacts can cause misalignment between the pusher and stamping timing (e.g., if the pusher pushes too early, the strip will not leave the mold cavity; if it pushes too late, it will affect the next stamping cycle). When changing molds, the cam phase or limit switch position needs to be manually adjusted, which takes a long time to debug and is prone to failure due to operational errors. Utility Model Content

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.

[0023] Please see Figure 1-7 As shown, this utility model is a continuous stamping die template connecting mechanism, including an upper die 1, a lower die 2, and a base 3. A fixed frame 4 is fixedly connected to the top of the base 3, and a continuous drive mechanism 5 is provided on the fixed frame 4. The continuous drive mechanism 5 includes two connecting plates 51 fixedly connected to the fixed frame 4. A guide groove 52 is fixedly connected between the bottoms of the two connecting plates 51. A first motor 53 is fixedly connected to the right side of the right connecting plate 51. The first motor 53 is a servo geared motor, which can precisely control the rotation speed and rotation angle of the output shaft. At the same time, its output shaft has a locking function, which can lock the output shaft to ensure stability when not moving. The first motor 53 is electrically connected to an external power supply and is controlled by an external program. Each connecting plate 51 has a rotating shaft 54 ​​rotatably connected to its inner wall. The surfaces of the two rotating shafts 54 are fixedly connected to rotating arms 55. A connecting plate 56 is rotatably connected between the two rotating arms 55. A trigger rod 57 and a fixing rod 58 are fixedly connected to the surface of the connecting plate 56 respectively. A sliding seat 59 is fixedly connected to the bottom end of the fixing rod 58. A connecting column 510 is fixedly connected to the bottom of the sliding seat 59. Through the continuous drive mechanism 5, the upper die 1 can drive the stamping template 7 to continuously stamp the workpiece. At the same time, the controller 8 is triggered once for each stamping. The controller 8 controls the entire continuous pushing mechanism 6 to push the material once, ensuring that the stamping and pushing frequencies are consistent, ensuring the continuity of work, and preventing malfunctions caused by misoperation.

[0024] The upper mold 1 is fixedly connected to the bottom of the connecting column 510, and the top of the base 3 is provided with a continuous pushing mechanism 6.

[0025] The continuous feeding mechanism 6 includes a second motor 61 fixedly connected to the top of the base 3, two connecting bars 62, and two support bars 63. The second motor 61 is a servo geared motor, which can precisely control the rotation speed and rotation angle of the output shaft. The second motor 61 is electrically connected to the controller 8 and is controlled by the controller 8 program. A bevel gear 64 is fixedly connected to the surface of the output shaft of the second motor 61. A connecting shaft 65 is rotatably connected to the inner wall of the two connecting bars 62. A transmission wheel 66 and a drive gear 67 are fixedly connected to the surface of the connecting shaft 65, respectively. Two guide bars 68 are fixedly connected between the tops of the two support bars 63. A rack 69 is slidably connected between the inner walls of the two guide bars 68. A connecting rod 610 is fixedly connected to the left side of the rack 69. A feeding plate 611 is fixedly connected to the left end of the connecting rod 610.

[0026] The bottom of the upper die 1 is fixedly connected to the stamping template 7. In the continuous stamping die template connection mechanism, the stamping template 7 is fixedly connected to the bottom of the upper die 1 and is the core working component that directly participates in the stamping and forming of the workpiece. Through the closing motion of the upper and lower dies, it applies pressure to the surface of the workpiece to complete processes such as punching, bending, and deep drawing. The lower die 2 is fixedly connected to the top of the base 3. A controller 8 is set on the fixed frame 4. The controller 8 is connected to the second motor 8 through a wire. The controller 8 receives signals to preset and program the second motor 8 to move.

[0027] The right rotating shaft 54 ​​is fixedly connected to the output end of the first motor 53, and the sliding joint 59 is slidably connected to the guide groove 52.

[0028] The bevel gear 64 and the transmission wheel 66 are matched, and the drive gear 67 and the rack 69 are meshed.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] The working principle of this utility model is as follows: First, the workpiece is placed on the lower mold 2. Then, the first motor 53 is started, which drives the right rotating arm 55 to rotate via the right rotating shaft 54. When the right rotating arm 55 rotates, it drives the connecting plate 56, which in turn drives the left rotating arm 55. The left rotating arm 55 rotates within the inner wall of the left connecting plate 51 via the left rotating shaft 54. When the connecting plate 56 moves, it drives the sliding seat 59 to continuously reciprocate up and down within the inner wall of the guide groove 52 via the fixed rod 58. This causes the sliding seat 59 to drive the upper mold 1 and the stamping template 7 to press the workpiece via the connecting column 510. At the same time, each time the connecting plate 56 moves, the trigger rod 57 on its surface presses and triggers the controller 8 once, causing the controller 8 to control the second motor 6. 1. Start-up: The output shaft drives the bevel gear 64 to rotate once. The bevel gear 64 rotates once, driving the transmission wheel 66. The transmission wheel 66 rotates once between the inner walls of the two connecting bars 62 via the connecting shaft 65. When the connecting shaft 65 rotates, the drive gear 67 on its surface rotates synchronously. When the drive gear 67 rotates, it drives the rack 69, causing the rack 69 to move to the left between the inner walls of the two guide bars 68. When the rack 69 moves, it drives the pusher plate 611 to move to the left via the connecting rod 610, pushing the workpiece to the left. As the connecting plate 56 continues to move, the trigger rod 57 continuously presses the trigger controller 8. Each time the controller 8 is pressed and triggered, it controls the first motor 53 to rotate once, causing the pusher plate 611 to continuously push the workpiece intermittently.
