Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip feeding technology, and in particular to a strip feeding structure for stamping dies. Background Technology
[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Stamping is a forming process that uses a press and mold to apply external force to sheet metal, strip, pipe and profile, causing plastic deformation or separation, thereby obtaining workpieces of the required shape and size.
[0003] Currently, most strip feeding in stamping is done by pulling and supporting rollers, with one end of the strip placed on the lower die of the stamping mold. Although this feeding method is the simplest, it is prone to uneven strip tension, which is detrimental to the consistency of the product's appearance. Therefore, a positioning and feeding device for molds is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a material feeding structure for stamping dies, which effectively solves the deficiencies of the prior art.
[0005] To achieve the above objectives, one embodiment of this utility model provides a material feeding structure for stamping dies, including a die body. A guide rail is provided on one side of the die body, and two mounting seats with opposite or reverse movement are provided inside the die body. A mounting frame is fixedly connected to the top of each of the two mounting seats, and a support roller is rotatably connected to the top of each of the two mounting frames. A first drive motor is fixedly connected to one corner of the bottom surface of each of the two mounting frames. Four feed discs are provided inside each of the two mounting frames, and the four are arranged in pairs. The bottom two feed discs are fixedly connected to the output ends of the two first drive motors, and two limiting posts are fixedly connected to the middle of the top surface of each of the bottom two feed discs, and the four are slidably connected to the top two feed discs. A clamping ring is fixedly connected to the edge of the adjacent surfaces of the four feed discs. Two springs are provided between each of the four feed discs. An arc-shaped protrusion is provided on one side of the top surface of each of the top two feed discs, and the two protrusions cooperate with the two support rollers respectively.
[0006] Preferably, in any of the above solutions, the bottom surface of each guide rail is fixedly connected with a fixing bracket, and the bottom ends of both fixing brackets are fixedly connected to the mold body. This solution facilitates the provision of installation positions for the two guide rails, thereby facilitating the stable installation of the guide rails on one side of the mold body. The two sets of feed discs face the mold body, and by rotating the two sets of feed discs, the two support rollers come into contact with the two arc-shaped protrusions, which is then used to control the vertical movement of the two top feed discs, and to clamp and release the material strip at intervals.
[0007] Preferably, one end of the guide rail is fixedly connected to a second drive motor, and its output end is fixedly connected to a bidirectional lead screw. The bidirectional lead screw is threadedly connected to the bottom ends of the two mounting seats. This design facilitates the formation of a lead screw and nut drive mechanism, which in turn facilitates the operation of the second drive motor by powering it on, driving the two mounting seats to move in opposite directions or in reverse. This facilitates changing the distance between the two mounting seats, thereby facilitating the feeding operation of material strips of different widths.
[0008] Preferably, in any of the above schemes, hollow columns are fixedly connected to the sides of the four feed discs that are far apart from each other, and two springs are slidably connected inside the four hollow columns. This scheme facilitates the provision of installation positions for the two springs, and the two springs push the two feed discs at the top. After the two support rollers move away from the arc-shaped protrusion, it is convenient to lift the two feed discs at the top to a certain height, thereby realizing the release of the material strip by the two clamping rings.
[0009] Preferably, in any of the above schemes, the length of the two limiting posts is greater than twice the thickness of the feed disk, and the two limiting posts and the two hollow posts are arranged in a circumferential array on the surface of the feed disk. By using this scheme, it is easy for the two limiting posts to completely penetrate the top two feed disks, thereby facilitating the rotation of the two sets of feed disks by the two first drive motors respectively.
[0010] Preferably, both ends of the two arc-shaped protrusions are provided with bevels. This design facilitates a smooth transition of the two ends of the arc-shaped protrusions towards the top surface of the two top feed discs, ensuring smooth vertical movement of the two top feed discs, and thereby pressing or releasing the material strip through the two clamping rings.
[0011] This utility model has the following advantages:
[0012] 1. The material feeding structure of this stamping die consists of two mounting brackets, four feeding discs, two first drive motors, four limit posts, arc-shaped protrusions, and two support rollers. The output ends of the two first drive motors are fixedly connected to the two bottom feeding discs, and the four limit posts are slidably connected to the two top feeding discs. When the first drive motors are powered on, they drive the four feeding discs to rotate. At the same time, the two arc-shaped protrusions and the two support rollers roll relative to each other, pushing the two top feeding discs to descend. This causes the two clamping rings to clamp the edge of the material strip and push it forward, achieving automatic feeding. Because the feeding position is close to the die body, the feeding amount is guaranteed to be the same each time, ensuring a uniform appearance of the product.
[0013] 2. The material feeding structure of this stamping die is equipped with a guide rail, a bidirectional lead screw, a second drive motor, and two mounting seats. The bidirectional lead screw is threadedly connected to the two mounting seats. When the second drive motor is energized, it drives the bidirectional lead screw to rotate, thereby driving the two mounting seats to move relative to each other or in opposite directions. This changes the distance between the two sets of feed discs, making it easier to feed material strips of different widths, thus improving the overall practicality. Attached Figure Description

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0022] like Figures 1 to 6 As shown, a material feeding structure for a stamping die includes a die body 1. A guide rail 6 is provided on one side of the die body 1. Two mounting seats 12 with opposite or reverse motion are provided inside the die body 1. Mounting brackets 3 are fixedly connected to the top of each of the two mounting seats 12. Support rollers 4 are rotatably connected to the top of each of the two mounting brackets 3. A first drive motor 7 is fixedly connected to one corner of the bottom surface of each of the two mounting brackets 3. Four feed discs 5 are provided inside each of the two mounting brackets 3, and the four are arranged in pairs. The bottom two feed discs 5 are fixedly connected to the output ends of the two first drive motors 7 respectively. Two limiting posts 2 are fixedly connected to the middle of the top surface of each of the bottom two feed discs 5, and the four are slidably connected to the top two feed discs 5 respectively. A clamping ring 15 is fixedly connected to the edge of the adjacent surfaces of the four feed discs 5. Two springs 10 are provided between each of the four feed discs 5. An arc-shaped protrusion 14 is provided on one side of the top surface of each of the top two feed discs 5, and the two protrusions cooperate with the two support rollers 4 respectively.
[0023] The bottom surface of each guide rail 6 is fixedly connected with a fixing bracket 8. The bottom ends of the two fixing brackets 8 are fixedly connected to the mold body 1. As an optional technical solution of this utility model, this facilitates the provision of installation positions for the two guide rails 6, and makes it easier to stably install the guide rails 6 on one side of the mold body 1, so that the two sets of feed discs 5 face the mold body 1. By rotating the two sets of feed discs 5, the two support rollers 4 come into contact with the two arc-shaped protrusions 14, which is used to control the vertical movement of the two top feed discs 5, and to clamp and release the material strip at intervals.
[0024] One end of the guide rail 6 is fixedly connected to a second drive motor 11, and its output end is fixedly connected to a bidirectional lead screw 13. The bidirectional lead screw 13 is threadedly connected to the bottom ends of the two mounting seats 12. As an optional technical solution of this utility model, this facilitates the formation of a lead screw and nut drive mechanism, and facilitates the operation of the second drive motor 11 by powering on, driving the two mounting seats 12 to move in opposite directions or in reverse, thereby facilitating the change of the distance between the two mounting seats 12, and thus facilitating the feeding operation of material strips of different widths.
[0025] Hollow columns 9 are fixedly connected to the four feed discs 5 on their opposite sides. Two springs 10 are slidably connected inside the four hollow columns 9. As an optional technical solution of this utility model, this facilitates the provision of installation positions for the two springs 10. At the same time, the two springs 10 push the two feed discs 5 at the top, and after the two support rollers 4 move away from the arc-shaped protrusion 14, it is easier to lift the two feed discs 5 at the top to a certain height, thereby realizing the release of the material strip by the two clamping rings 15.
[0026] The length of the two limiting posts 2 is more than twice the thickness of the feed disk 5. The two limiting posts 2 and the two hollow posts 9 are arranged in a circumferential array on the surface of the feed disk 5. As an optional technical solution of this utility model, this makes it easy for the two limiting posts 2 to completely penetrate the two top feed disks 5, and thus makes it easy for the two sets of feed disks 5 to be rotated by the two first drive motors 7 respectively.
[0027] Both ends of the two arc-shaped protrusions 14 are provided with bevels. As an optional technical solution of this utility model, this facilitates the smooth transition of the two ends of the two arc-shaped protrusions 14 towards the top surface of the two top feed discs 5, ensuring that the two top feed discs 5 move smoothly and vertically, and then the material strip is pressed or released by the two clamping rings 15.
[0028] This stamping die uses a strip feed structure and requires the following steps when used:
[0029] 1) When in use, the second drive motor 11 is powered on and runs, driving the two mounting bases 12 to move relative to or in opposite directions, thereby causing the two sets of feed discs 5 to move to the designated position;
[0030] 2) Place one end of the strip between the four feed discs 5, while simultaneously penetrating the mold body 1;
[0031] 3) The two first drive motors 7 are powered on and run, respectively driving the two sets of feed discs 5 to rotate;
[0032] 4) The two arc-shaped protrusions 14 and the two support rollers 4 roll relative to each other, pushing the two top feed discs 5 to descend in height, so that the two clamping rings 15 clamp the edge of the material strip and push it forward to achieve automatic feeding.
[0033] In summary, during operation, the system comprises two mounting brackets 3, four feed discs 5, two first drive motors 7, four limiting posts 2, arc-shaped protrusions 14, and two support rollers 4. The output ends of the two first drive motors 7 are fixedly connected to the two bottom feed discs 5, and the four limiting posts 2 are slidably connected to the two top feed discs 5. When the first drive motors 7 are energized, they rotate the four feed discs 5. Simultaneously, the two arc-shaped protrusions 14 and the two support rollers 4 roll relative to each other, pushing the two top feed discs 5 to descend, causing the two clamping rings 15 to contact the edge of the material strip. The material is clamped and pushed forward to achieve automatic feeding. Since the feeding position is close to the mold body 1, the feeding amount is kept the same each time, ensuring that the product appearance is uniform. The system is equipped with a guide rail 6, a bidirectional lead screw 13, a second drive motor 11, and two mounting seats 12. The bidirectional lead screw 13 is threadedly connected to the two mounting seats 12. The second drive motor 11 is powered on and runs, which drives the bidirectional lead screw 13 to rotate, thereby driving the two mounting seats 12 to move relative to each other or in opposite directions. This changes the distance between the two sets of feed discs 5, making it easier to feed strips of different widths and improving the overall practicality.
