The bottom of the connecting ring is fixedly connected to a first spring. The lower end of the first spring is fixedly connected to the inner bottom of the installation groove. The first spring is sleeved outside the ejecting rod. A spherical block is fixed to the bottom of the ejecting rod. An arc-shaped block matched with the spherical block is fixed to the upper end of the support plate. A driving column that moves up and down reciprocally is provided through the cross plate. A forming plate matched with the forming groove is fixed to the bottom of the driving column.

[0009] Preferably, a first shaft rod is rotatably connected between the two fixing plates. A worm is fixedly connected to the first shaft rod. A worm gear is fixedly connected to the rotating column. The worm is meshed with the worm gear. A vertical plate is fixedly connected to the upper end of the base. A motor is installed on the vertical plate. The output end of the motor is fixedly connected to a second shaft rod. The second shaft rod passes through the vertical plate and is rotatably connected to it. A third shaft rod passes through the fixing plate and is rotatably connected to it. A first gear is fixedly connected to the first shaft rod. A second gear is fixedly connected to the second shaft rod. The first gear is meshed with the second gear.

[0010] Preferably, the second gear is an incomplete gear.

[0011] Preferably, a plurality of brackets are fixedly connected to the bottom of the circular plate. Support wheels are installed on the brackets. The support wheels abut against the upper end of the support plate.

[0012] Preferably, the buffer ejecting member includes a moving plate fixedly connected to the upper end of the ejecting rod. A sliding groove is provided on the upper end of the moving plate. A sliding plate is slidably connected in the sliding groove. A plurality of exhaust holes are provided through the sliding plate. A plurality of second springs are fixedly connected between the sliding plate and the sliding groove. A plurality of support blocks are fixedly connected to the upper end of the sliding groove. A positioning block is fixedly connected to the upper end of the sliding plate. A top block is fixedly connected to the upper end of the positioning block.

[0013] Preferably, a third shaft rod rotatably connected thereto is penetrated through the fixed plate. Transmission wheels are installed on both the third shaft rod and the second shaft rod.

[0015] Preferably, the arc-shaped block is arranged close to the front side of the circular plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The intermittent rotation of the first gear drives the intermittent rotation of the first shaft rod. The intermittent rotation of the first shaft rod drives the intermittent rotation of the worm. The intermittent rotation of the worm drives the intermittent rotation of the worm wheel, thereby realizing the intermittent rotation of the rotating column. The rotation of the rotating column drives the intermittent rotation of the circular plate. When the circular plate is stationary, the forming groove and the forming plate are opposite at this time for forming work.

[0018] 2. When the forming plate extends into the forming groove, the first gear and the second gear are not meshed at this time. Therefore, when the forming plate extends into the forming groove, the metal material can be stamped and formed.

[0019] 3. The second spring can buffer the ejecting block, the positioning block and the sliding plate. At the same time, when the sliding plate moves downward, it can squeeze the air, so that the air is discharged through the exhaust hole, and then the ejecting block can be effectively buffered. Finally, the sliding plate moves downward and abuts against the supporting block, and the positioning block and the sliding plate cannot move downward. The forming plate can work to extrude and form the metal material.

[0020] 4. The rotation of the circular plate drives the rotation of the ejecting rod. When the ejecting rod rotates and abuts against the arc-shaped block, under the limit of the arc-shaped block, the ejecting rod can move upward. The upward movement of the ejecting rod drives the buffer ejecting part upward, and the formed metal material can be ejected, which is convenient for the staff to take.

[0021] 5. It avoids the drawback in the prior art that only after the previous stamping part is completed and the stamping part is taken off can the next stamping work be carried out, thus reducing the stamping efficiency of the metal material.

[0022] In summary, the present invention avoids the drawback in the prior art that only after the stamping part completes the previous stamping and the stamping part is taken off can the next stamping work be carried out, resulting in low stamping efficiency. In the present invention, the staff stands at the front side and away from the forming plate, and only needs to take off the formed metal material and place the unformed metal material, and can realize the continuous processing of the metal material, greatly improving the processing efficiency of the metal material, and the working process is safer.

[0031] When the motor 10 works, it drives the second shaft 13 to rotate. The rotation of the second shaft 13 drives the second gear 12 to rotate. The rotation of the second gear 12 drives the first gear 11 to rotate. Since the second gear 12 is an incomplete gear, the second gear 12 intermittently drives the first gear 11 to rotate. The intermittent rotation of the first gear 11 drives the intermittent rotation of the first shaft 11. The intermittent rotation of the first shaft 11 drives the intermittent rotation of the worm 7. The intermittent rotation of the worm 7 drives the intermittent rotation of the worm gear 8, thereby realizing the intermittent rotation of the rotating column 4;

[0032] The rotating column 4 penetrates through the support plate 38 and is rotatably connected thereto. A circular plate 5 is fixedly connected to the upper end of the rotating column 4. A plurality of brackets are fixedly connected to the bottom of the circular plate 5. Support wheels 23 are installed on the brackets. The support wheels 23 abut against the upper end of the support plate 38, so that the circular plate 5 rotates more stably;

[0033] A plurality of forming grooves 22 are provided on the upper end of the circular plate 5. The plurality of forming grooves 22 are arranged in an annular array on the upper end of the circular plate 5. The forming plate 20 is arranged close to the rear side of the circular plate 5; an installation groove 24 is provided at the inner bottom of the forming groove 22. The ejector rod 27 penetrates through the circular plate 5 and is slidably connected thereto. A connecting ring 25 is fixedly connected to the ejector rod 27. The connecting pipe 25 is slidably connected in the installation groove 24. A first spring 26 is fixedly connected to the bottom of the connecting ring 25. The lower end of the first spring 26 is fixedly connected to the inner bottom of the installation groove 24. The first spring 26 is sleeved outside the ejector rod 27. A spherical block 28 is fixed to the bottom of the ejector rod 27. An arc-shaped block 21 matched with the spherical block 28 is fixed to the upper end of the support plate 38. The arc-shaped block 21 is arranged close to the front side of the circular plate 5; when the rotating column 4 rotates to drive the circular plate 5 to rotate, and the ejector rod 27 rotates and abuts against the arc-shaped block 21, under the limit of the arc-shaped block 21, the ejector rod 27 can be moved upward;

[0034] A buffer ejector 29 is slidably connected in the forming groove 22. A ejector rod 27 is fixedly connected to the bottom of the buffer ejector 29. The upward movement of the ejector rod 27 drives the upward movement of the buffer ejector 29. Explanation of the buffer ejector 29: The buffer ejector 29 includes a moving plate 30 fixedly connected to the upper end of the ejector rod 27. A chute 31 is provided at the upper end of the moving plate 30. A sliding plate 34 is slidably connected in the chute 31. A plurality of exhaust holes 35 penetrate through the sliding plate 34. A plurality of second springs 32 are fixedly connected between the sliding plate 34 and the chute 31. A plurality of support blocks 33 are fixedly connected to the upper end of the chute 31. A positioning block 36 is fixedly connected to the upper end of the sliding plate 34. An ejector block 37 is fixedly connected to the upper end of the positioning block 36.

[0035] A driving column 19 that moves up and down reciprocally penetrates through the transverse plate 3. A forming plate 20 that is arranged in cooperation with the forming groove 22 is fixed to the bottom of the driving column 19. A third shaft rod 16 that is rotatably connected to the fixed plate 2 penetrates through the fixed plate 2. Transmission wheels 14 are installed on both the third shaft rod 16 and the second shaft rod 13. The two transmission wheels 14 are connected by a belt 15. A disc 17 is fixedly connected to the third shaft rod 16. A connecting rod 18 is eccentrically hinged to the disc 17. The connecting rod 18 is hinged to the upper end of the driving column 19.

[0036] When the present invention is in use, the staff places the metal material in the forming groove 22 and starts the motor 10. The operation of the motor 10 drives the rotation of the second shaft rod 13. The rotation of the second shaft rod 13 drives the rotation of the second gear 12. The rotation of the second gear 12 drives the rotation of the first gear 11. Since the second gear 12 is an incomplete gear, the second gear 12 intermittently drives the first gear 11 to rotate. The intermittent rotation of the first gear 11 drives the intermittent rotation of the first shaft rod 11. The intermittent rotation of the first shaft rod 11 drives the intermittent rotation of the worm 7. The intermittent rotation of the worm 7 drives the intermittent rotation of the worm wheel 8, thereby realizing the intermittent rotation of the rotating column 4. The rotation of the rotating column 4 drives the intermittent rotation of the circular plate 5. When the circular plate 5 is stationary, at this time, the forming groove 22 and the forming plate 20 are opposite to each other.

[0037] The rotation of the second shaft rod 13 drives the rotation of the transmission wheel 14. Under the transmission of the belt 15, the rotation of the third shaft rod 16 is realized. The rotation of the third shaft rod 16 drives the rotation of the disc 17. The rotation of the disc 17 drives the connecting rod 18, the driving column 19 and the forming plate 20 to move up and down reciprocally. When the forming plate 20 extends into the forming groove 22, at this time, the first gear 11 and the second gear 12 are not engaged. Therefore, when the forming plate 20 extends into the forming groove 22, it can stamp and form the metal material.

[0038] When the forming plate 20 moves downward and extends into the forming groove 22, it first abuts against the metal material, and then squeezes the buffer ejector 29, that is, squeezes the ejector block 37 to move downward, and the ejector block 37 moves downward to drive the positioning block 36 and the slide plate 34 to move downward. The ejector block 37, the positioning block 36, and the slide plate 34 can be buffered by the second spring 32. At the same time, the slide plate 34 moves downward to squeeze the air, so that the air is discharged through the exhaust hole 35, and then the ejector block 37 can be effectively buffered. Finally, the slide plate 34 moves downward to abut against the support block 33, and the positioning block 36 and the slide plate 34 cannot move downward. The forming plate 20 can extrude and form the metal material.

[0039] Then the disc 17 drives the connecting rod 18, the driving column 19 and the forming plate 20 to move upward, and the first gear 11 is meshed with the second gear 12, so the disc 5 is driven to rotate again, and another forming groove 22 with metal material is placed opposite to the forming plate 20, and the above operation is repeated;

[0040] The circular plate 5 rotates to drive the ejector rod 27 to rotate. When the ejector rod 27 rotates and contacts the arc block 21, the ejector rod 27 can move upward under the limit of the arc block 21. The upward movement of the ejector rod 27 drives the buffer ejector 29 to eject the formed metal material, which is convenient for the staff to take. When the ejector rod 27 is separated from the arc block 21, the buffer ejector 29 can be reset under the action of the first spring 26, and the staff can stand at the front side and put the metal material in the forming groove 22.

[0041] That is, the staff stands at the front side and away from the forming plate 20, and only needs to remove the formed metal material and place the unformed metal material, which can realize continuous processing of the metal material, greatly improves the efficiency of metal material processing, and makes the working process safer.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
