[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a processing device for a continuous die of circular products without joint cutting edges and full - circumference deburring, including a lower die and an upper die. The lower die includes a lower die base 1. In the middle of the top of the lower die base 1, a fixed ring 14 is fixedly connected. On the top of the fixed ring 14, a chamfering ring 16 is fixedly connected. In the middle of the inner cavity of the fixed ring 14, a blank holding block 15 is movably connected. The blank holding block 15 is connected to the lower die base 1 through a first hydraulic telescopic rod 12. The end of the output shaft of the first hydraulic telescopic rod 12 is fixedly connected to the blank holding block 15, and the other end of the first hydraulic telescopic rod 12 is fixedly connected to the lower die base 1. Through the setting of the first hydraulic telescopic rod 12, the telescopic movement of the first hydraulic telescopic rod 12 can change the position of the blank holding block 15 fixedly connected thereto.

[0026] The outer diameter of the blank holding block 15 is the same as the inner diameter of the fixed ring 14, and the inner diameter of the bottom of the chamfering ring 16 is the same as the inner diameter of the fixed ring 14. The outer ring of the chamfering ring 16 is movably connected to a cutting die 17. The cutting die 17 includes a fixing plate and a cutting knife 3 fixedly connected to the middle of the top of the fixing plate. The bottom of the fixing plate is fixedly connected to a second hydraulic telescopic rod 13. The other end of the second hydraulic telescopic rod 13 is fixedly connected to the lower die base 1. Through the setting of the second hydraulic telescopic rod 13, the telescopic movement of the second hydraulic telescopic rod 13 can change the position of the fixing plate fixedly connected thereto. When the fixing plate moves, it drives the cutting knife 3 fixedly connected thereto to move.

[0027] The inner wall of the chamfering ring 16 is a conical structure, and the outer wall of the chamfering ring 16 is a cylindrical structure. The inner diameter of the cutting tool 3 is the same as the outer diameter of the chamfering ring 16, and the inner wall of the cutting tool 3 and the outer wall of the chamfering ring 16 can be in a closely fitting state to ensure the cutting quality. And when the top of the cutting tool 3 and the top of the chamfering ring 16 are flush, the contact part between the cutting tool 3 and the chamfering ring 16 is the cutting part of the workpiece. After the workpiece is chamfered, when the hydraulic telescopic rod II 13 drives the cutting tool 3 to move upward, the cutting tool 3 can cut the redundant part of the workpiece. This equipment realizes the chamfering and cutting functions of the workpiece, meeting the requirements of no joint cutting edge and full-circumference deburring.

[0028] The above-mentioned hydraulic telescopic rod II 13 is located outside the fixed ring 14. The top of the lower die base 1 is fixedly connected with a lower sealing frame 2. The outer ring of the top end of the lower sealing frame 2 is movably connected with an upper sealing frame 7. The upper sealing frame 7 is fixedly connected with the cutting die 17. The hydraulic telescopic rod II 13 is located inside the cavity of the lower sealing frame 2. Through the settings of the lower sealing frame 2 and the upper sealing frame 7, the cavity of the lower die base 1 can be in a sealed state to prevent impurities from entering the cavity of the lower die base 1.

[0029] The upper die includes an upper die base 4. The lower die base 1 and the upper die base 4 are connected by a hydraulic telescopic rod III 11. The end of the output shaft of the hydraulic telescopic rod III 11 is fixedly connected with the upper die base 4, and the other end of the hydraulic telescopic rod III 11 is fixedly connected with the lower die base 1. The telescoping of the hydraulic telescopic rod III 11 can change the distance between the upper die and the lower die.

[0030] In the middle of the bottom of the upper die base 4, a pressing punch 5 is fixedly connected. The outer diameter of the pressing punch 5 is the same as the inner diameter of the top of the chamfering ring 16. Through the settings of the pressing punch 5 and the chamfering ring 16, when the pressing punch 5 presses the workpiece, the workpiece can be chamfered.

[0031] The outer ring of the pressing punch 5 is movably connected with a lifting plate 6. The lifting plate 6 and the upper die base 4 are connected by a hydraulic telescopic rod IV 8. During the chamfering process of the workpiece, the lifting plate 6 presses other parts of the workpiece, enabling the workpiece to be ribbed, which is convenient for cutting the redundant parts of the workpiece.

[0032] On one side of the upper die base 4 and one side of the lifting plate 6, a limiting ring 9 is fixedly connected. A limiting rod 10 is movably sleeved inside the cavity of the limiting ring 9. The limiting rod 10 is fixedly connected with the lower die base 1. Through the settings of the limiting rod and the limiting ring 9, the moving direction of the upper die can be limited, ensuring the processing accuracy of the equipment.

[0033] In summary, when the processing equipment of the circular product without connecting knife edge and full - circumference deburring continuous die is in use, the lower die is fixed at a suitable position on the circular product continuous die production line. The circular product to be processed is placed on the top of the lower die, and at this time, the tops of the pressure block 15, the cutting knife 3 and the chamfering ring 16 are at the same height. The hydraulic telescopic rod three 11 drives the upper die base 4 to move downward. The upper die base 4 drives the pressing punch 5 and the lifting plate 6 to move downward, and at this time, the bottom of the lifting plate 6 and the bottom of the pressing punch 5 are at the same height. When the top of the pressing punch 5 contacts the top of the circular product, the hydraulic telescopic rod one 12 starts to work. The hydraulic telescopic rod one 12 drives the pressure block 15 to move downward, and the pressure block 15 and the pressing punch 5 are in a relatively static state. During the downward movement of the circular product, the circular product is chamfered, and the lifting plate 6 performs a rib pressing operation on the product. After the circular product completes the chamfering operation, the hydraulic telescopic rod three 11 and the hydraulic telescopic rod one 12 stop working. The hydraulic telescopic rod four 8 drives the lifting plate 6 to move upward, so that the lifting plate 6 is separated from the circular product. The hydraulic telescopic rod two 13 drives the cutting die 17 to move upward. The cutting die 17 drives the cutting knife 3 to cut the redundant part of the circular product. After the cutting is completed, the cutting die 17 is reset under the action of the hydraulic telescopic rod two 13. The hydraulic telescopic rod three 11 and the hydraulic telescopic rod one 12 both extend. The extension of the hydraulic telescopic rod three 11 separates the upper die from the circular product. The extension of the hydraulic telescopic rod one 12 pushes the product out of the chamfering ring 16, which is convenient for the demoulding of the product and the reuse of the equipment.

The special - shaped parts can be customized according to the description in the specification and the drawings.
