[0016] In one possible design, a limiting groove is formed on the top of the platform, and an inclined baffle is slidably connected in the limiting groove. The top of the inclined baffle extends above the platform, and the inclined part of the inclined baffle contacts one side of the support plate.

Multiple second compression springs are fixedly installed at equal intervals at the bottom of the inclined baffle, and the bottom end of the second compression spring is fixedly connected to the bottom inner wall of the limiting groove.
[0017] In this application, after the sheet metal to be stamped is placed on the lower die located on the outer side of the table, the drive motor can be started to drive the half gear to rotate. At this time, when the half gear rotates with the drive gear, it can drive the rotating shaft to rotate 180°, thereby moving the lower die with the sheet metal placed on it onto the table. Then, when the half gear meshes with the transmission gear, it can drive the connecting shaft to rotate. Then, under the meshing transmission action of the first bevel gear and the second bevel gear, it can drive the curved rod to rotate circumferentially. When the curved rod rotates, under the transmission action with the connecting frame, it can cause the connecting frame to move longitudinally back and forth along the two limit frames. When the connecting frame moves downward, it can drive the upper die to move downward. Thus, under the cooperation of the corresponding lower die, the sheet metal can be stamped and formed. Afterward, the sheet metal to be stamped next is placed on another lower die. When the half gear continues to mesh with the drive gear, the next sheet metal can be moved onto the table. Therefore, it can continuously stamp the sheet metal. When the chuck rotates with the curved rod, the positioning frame can be moved out of the arc-shaped slot. After the curved rod rotates one revolution, when the upper die is moved to the initial position, the first compression spring under force can push the positioning frame to move downward, so that the positioning frame is engaged with the arc-shaped slot, thereby positioning the chuck and preventing the curved rod from rotating. This can stably limit the upper die. At the same time, when the pallet rotates 180° with the rotating shaft, it will keep in contact with the inclined surface of the inclined stop bar. The inclined stop bar can be used to brake the pallet, eliminate the rotational inertia of the pallet, and keep it stationary. When the pallet rotates with the rotating shaft, the pallet will exert pressure on the inclined stop bar, causing the inclined stop bar to move downward and compress multiple second compression springs. Therefore, after the pallet and the inclined stop bar are disengaged, the multiple second compression springs under force can push the inclined stop bar to move upward and reset.
[0018] Beneficial effects: In this utility model, the continuous feeding device for a stamping machine can rotate 180° after the rotating shaft receives the driving force of the power mechanism through the feeding mechanism. This can drive the pallet to rotate, thereby moving the two lower dies to the bottom of the pressing mechanism. Therefore, after the sheet material to be stamped is placed on the lower die, the sheet material can be moved to the bottom of the pressing mechanism, which facilitates the stamping of the sheet material.
[0019] In this utility model, the continuous feeding device for a stamping machine, through the pressing mechanism, can drive the connecting frame to perform longitudinal reciprocating motion after the transmission component receives the driving force of the power mechanism. When the connecting frame moves downward, it can drive the upper die to move downward, so that the sheet metal can be stamped and formed under the cooperation of the corresponding lower die.
[0020] In this utility model, the continuous feeding device for a stamping machine, through a power mechanism, can drive the gear assembly by starting the drive motor. At this time, it can drive the rotating shaft to rotate 180° and drive the connecting shaft to rotate circumferentially, thereby moving the lower die holding the sheet metal to below the upper die, and then driving the curved rod to rotate circumferentially, thereby realizing the braking stamping of the sheet metal.
[0021] This invention can automatically move the two lower dies to positions corresponding to the upper die, and the upper die can continuously reciprocate longitudinally, thereby enabling continuous stamping of sheet metal and effectively improving the stamping efficiency of sheet metal, thus having good practicality.

[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] Example 1: Refer to Figures 1-5 A feeding device includes a base 1, with a vertical plate 2 fixedly mounted on one side of the top of the base 1. A platform 3 is fixedly fitted onto the vertical plate 2, providing a stable working platform for the device. A top plate 8 is fixedly mounted on the top of one side of the vertical plate 2 for supporting and mounting a pressing mechanism.
[0030] On the top of the base 1, we installed a feeding mechanism. The feeding mechanism mainly consists of a rotating shaft 4 rotatably connected to the top of the base 1. The rotating shaft 4 is rotatably connected to one side of the table 3, allowing the rotating shaft 4 to rotate relative to the table 3. On the rotating shaft 4, we fixedly mounted a support plate 5 located above the table 3, with one side of the support plate 5 in contact with the top of the table 3. Two first clamping covers 6 are symmetrically fixedly mounted on the top of the support plate 5, and each first clamping cover 6 has a lower die 7 clamped on it for placing the sheet metal to be stamped.
[0031] To achieve the rotation of the pallet 5, the rotating shaft 4 is connected to the power mechanism. The power mechanism includes a drive motor 15 fixedly mounted on the top of the base 1, and a gear assembly mounted on the output shaft of the drive motor 15. The gear assembly includes a half gear 16 fixedly mounted on the output shaft of the drive motor 15, a drive gear 17 fixedly sleeved on the rotating shaft 4, and a transmission gear 19 fixedly mounted on the bottom end of the connecting shaft 18. The half gear 16 is movably meshed with both the drive gear 17 and the transmission gear 19. When the drive motor 15 is started, the half gear 16 rotates, thereby driving the drive gear 17 and the transmission gear 19 to rotate. Due to the characteristics of the half gear 16, when it meshes with the drive gear 17, it drives the rotating shaft 4 to rotate 180°, allowing the two lower dies 7 on the pallet 5 to move alternately below the upper die 12. At the same time, when the half gear 16 meshes with the transmission gear 19, it drives the connecting shaft 18 to rotate circumferentially, providing power for subsequent pressing operations.
[0032] The pressing mechanism is mounted on the top plate 8, including limiting frames 9 fixedly mounted on both sides of the top plate 8, with a connecting frame 10 slidably connected to the two limiting frames 9. A second retaining cover 11 is fixedly mounted on the bottom of the connecting frame 10, and an upper die 12 is clamped at the bottom of the second retaining cover 11 for stamping the sheet metal on the lower die 7. To achieve longitudinal movement of the connecting frame 10, a transmission assembly is installed at the bottom of the top plate 8. The transmission assembly includes a mounting plate 13 fixedly mounted on one side of the bottom of the top plate 8, with a curved rod 14 rotatably connected through the mounting plate 13. The curved rod 14 passes through the connecting frame 10 and engages with it in a transmission cooperation, so that the rotation of the curved rod 14 can drive the connecting frame 10 to perform longitudinal reciprocating movement. One end of the curved rod 14 is rotatably connected to the top side of the upright plate 2, and a chuck 25 is fixedly mounted on the other end. The top of the chuck 25 has an arc-shaped groove for clamping with the positioning frame 23. The positioning frame 23 is slidably sleeved on the limiting plate 22, which is fixedly installed on one side of the mounting plate 13. The bottom of the positioning frame 23 has an arc structure, which can extend into the arc-shaped slot and be movably engaged with the inner wall of the arc-shaped slot. A first compression spring 24 is fixedly installed on the inner wall of the bottom of the positioning frame 23, and the top of the first compression spring 24 is fixedly connected to the bottom of the limiting plate 22. When the chuck 25 rotates with the curved rod 14, the positioning frame 23 is moved out of the arc-shaped slot. After the curved rod 14 rotates one revolution, the first compression spring 24, which is under stress, will push the positioning frame 23 downward, so that the positioning frame 23 is engaged with the arc-shaped slot, thereby positioning the chuck 25 and preventing the curved rod 14 from rotating.
[0033] To enable the rotation of the curved rod 14, a first bevel gear 20 is fixedly installed at the top of the connecting shaft 18, and a second bevel gear 21 is fixedly sleeved on the curved rod 14. The first bevel gear 20 and the second bevel gear 21 mesh, so that the rotation of the connecting shaft 18 can drive the curved rod 14 to rotate.
[0034] This application can be used in the field of stamping machine technology, or in other fields applicable to this application.
[0035] Example 2: Reference Figure 2 and 5An improvement on Embodiment 1: A continuous feeding device for a stamping press, applied in the field of stamping press technology, includes a limiting groove on the top of the table 3 for limiting and stabilizing the feeding mechanism. A sloping stop bar 26 is slidably connected within the limiting groove. The top of the sloping stop bar 26 extends above the table 3, and its sloping portion contacts one side of the support plate 5. When the support plate 5 rotates 180° with the rotating shaft 4, it maintains contact with the sloping surface of the sloping stop bar 26, thus using the sloping stop bar 26 to block and limit the support plate 5. Multiple second compression springs 27 are fixedly installed at equal intervals at the bottom of the sloping stop bar 26, and the bottom ends of the second compression springs 27 are fixedly connected to the bottom inner wall of the limiting groove. When the support plate 5 applies pressure to the sloping stop bar 26, the sloping stop bar 26 moves downward and compresses the multiple second compression springs 27. When the support plate 5 disengages from the inclined baffle 26, the multiple second compression springs 27, which are under stress, will push the inclined baffle 26 to move upward and reset.
[0036] Through the design and implementation of the above structure, we can achieve continuous feeding and stamping operations of the stamping machine. When the sheet metal to be stamped is placed on the lower die 7, the drive motor 15 is started to drive the half gear 16 to rotate. The half gear 16 first meshes with the drive gear 17, driving the rotating shaft 4 to rotate 180°, moving the lower die 7 with the sheet metal placed on it below the upper die 12. Then the half gear 16 meshes with the transmission gear 19, driving the connecting shaft 18 to rotate circumferentially, thereby driving the curved rod 14 to rotate. The rotation of the curved rod 14 will drive the connecting frame 10 to perform longitudinal reciprocating motion, so that the upper die 12 stamps the sheet metal on the lower die 7. After completing one stamping operation, the drive motor 15 continues to rotate, driving the next lower die 7 to move below the upper die 12 for stamping operations, thereby achieving the purpose of continuous feeding and stamping.
[0037] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 15 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
