Specific implementation manner

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners:

[0026] As Figures 1 - 3 shown, the present utility model provides a punching mechanism of a nut cold heading machine, including a support base 1. A rotating frame 2 is arranged on the top of the support base 1. A support frame 3 is fixedly connected to the top of the rotating frame 2.

A punching hole 212 penetrating up and down is arranged on the left side of the inner part of the arc-shaped slide plate 210. An arc-shaped tooth plate 211 penetrating up and down is arranged on the right side of the inner part of the arc-shaped slide plate 210. A second moving groove is arranged in the middle of the connecting column 21. A first motor 22 is fixedly connected to the top end of the inner wall of the second moving groove. A driving wheel 23 is fixedly connected to the output shaft of the first motor 22. A driven wheel 24 is meshed with the outer surface of the driving wheel 23. A transmission gear ring 25 is meshed with the outer surface of the driven wheel 24. The transmission gear ring 25 is fixedly connected to the inner surface of the annular rotating seat 26;

[0027] When the stamping mechanism of the cold heading machine stamps the nut gasket, the raw material is placed on the feeding mechanism 5. By starting the first motor 22, the driving wheel 23 can be driven to rotate, and the driven wheel 24 can drive the transmission gear ring 25 to rotate, so that the annular rotating seat 26 can be driven to rotate. As a result, the raw material in the feeding mechanism 5 will fall onto the arc-shaped slide plate 210 in the blanking groove 27. With the rotation of the annular rotating seat 26, the raw material can be rotated to the bottom of the stamping machine 4. The stamping machine 4 can complete the stamping process of the nut gasket. The punched material will fall into the receiving box 6 behind through the punching hole 212 and the blanking groove 27. Then, under the conveyance of the annular rotating seat 26, the nut gasket can be rotated to the top of the receiving box 6 in the front. By starting the second motor 28, the arc-shaped tooth plate 211 can be driven to rotate through the transmission wheel 29, so that the arc-shaped slide plate 210 rotates, and the stamped nut gasket will fall into the receiving box 6 through the blanking hole 213 and the blanking groove 27, realizing the automatic collection of the nut gasket, making the processing of the nut gasket more convenient and avoiding the occurrence of safety hazards.

[0028] As Figure 4 shown, the present utility model provides a stamping mechanism for a nut cold heading machine. The feeding mechanism 5 includes a connecting frame 51. The connecting frame 51 is fixedly connected to the top right side of the support base 1. The top end of the connecting frame 51 is fixedly connected with a material placing cylinder 52. The material placing cylinder 52 is arranged on the top of the rotating frame 2. Both the front and rear sides of the outer surface of the material placing cylinder 52 are fixedly connected with support plates 53. The top ends of the two support plates 53 are fixedly connected with a top plate 54. The middle part of the top plate 54 is slidably connected with a sliding pull rod 55 that penetrates up and down. The top end of the sliding pull rod 55 is fixedly connected with a pulling handle 56. The bottom end of the sliding pull rod 55 penetrates into the interior of the material placing cylinder 52 and is fixedly connected with a pressing plate 57. The pressing plate 57 is slidably connected to the inner surface of the material placing cylinder 52. The top end of the pressing plate 57 is fixedly connected with a pressing spring 58. The top end of the pressing spring 58 is fixedly connected to the bottom end of the top plate 54;

[0029] During stamping, by pulling the pulling handle 56, the pressing plate 57 can be pulled out of the interior of the material placing cylinder 52 through the sliding pull rod 55, facilitating the placement of the raw material in the material placing cylinder 52. Then, release the pulling handle 56. Thus, under the pushing of the pressing spring 58, the pressing plate 57 can be pressed against the top of the raw material, so as to realize the automatic pushing of the raw material, enabling the raw material to automatically enter the rotating frame 2 and facilitating the stamping use of the nut gasket.

[0030] As Figure 5As shown in the figure, the present utility model provides a stamping mechanism for a nut cold heading machine. A pulling column 551 is slidably connected to the middle of a sliding pull rod 55. A first sliding groove is opened below the inside of the sliding pull rod 55. The bottom end of the pulling column 551 penetrates into the inside of the first sliding groove, and connecting rods 552 are movably connected to both the front and rear sides. The bottom end of the connecting rod 552 is movably connected to a positioning block 553. The positioning block 553 is slidably connected to the inside of the first sliding groove. Ejecting springs 554 are fixedly connected to the opposite surfaces of the two positioning blocks 553. Positioning card slots 541 are opened on both the front and rear sides of the inner surface of the top plate 54. One end of the positioning block 553 away from the ejecting spring 554 penetrates into the inside of the positioning card slot 541. A second sliding groove is opened inside the pulling handle 56. The top end of the pulling column 551 penetrates into the inside of the second sliding groove and is fixedly connected to a sliding pressing plate 561. The sliding pressing plate 561 is slidably connected to the inside of the second sliding groove, and both ends penetrate to the front and rear sides of the bottom surface of the outer surface of the pulling handle 56 respectively;

[0031] When the pressing plate 57 is pulled out by the pulling handle 56, under the pushing of the ejecting spring 554, the positioning block 553 can be made to snap into the inside of the positioning card slot 541, so that the position of the sliding pull rod 55 can be fixed, and the position of the pressing plate 57 can be fixed. Therefore, when placing the raw material, it is not necessary to keep pulling the pulling handle 56 all the time. By squeezing the sliding pressing plate 561, the pulling column 551 can be driven to slide, so that the connecting rod 552 can pull the positioning block 553 back, facilitating the pushing out of the pressing plate 57.

[0032] Next, specifically describe the working principle of the stamping mechanism of the nut cold heading machine.

[0033] As Figures 1 - 5As shown in the figure, when the stamping mechanism of the cold heading machine stamps the nut gasket, pulling the handle 56 can pull out the pressing plate 57 from the inside of the material placing cylinder 52, which facilitates placing the raw material in the material placing cylinder 52. Then, release the pulled handle 56, and the pressing plate 57 can be pressed against the top of the raw material through the pressing spring 58. After that, the first motor 22 drives the driving wheel 23 to rotate, and can drive the transmission gear ring 25 to rotate through the driven wheel 24, so as to drive the annular rotating seat 26 to rotate, making the pressing plate 57 push the raw material to fall onto the arc-shaped slide plate 210. With the rotation of the annular rotating seat 26, the raw material can be rotated to the bottom of the stamping machine 4, and the stamping machine 4 can complete the stamping process of the nut gasket. After that, under the conveyance of the annular rotating seat 26, the nut gasket can be rotated to the top of the front receiving box 6. The second motor 28 drives the transmission wheel 29 to rotate, and the arc-shaped slide plate 210 can be rotated through the arc-shaped tooth plate 211, so that the stamped nut gasket will fall into the receiving box 6 through the material dropping hole 213 and the material dropping groove 27, realizing the automatic collection of the nut gasket and making the processing of the nut gasket more convenient.

[0034] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
