[0002] In the field of metal product processing, operations such as shearing and curling of disc-shaped workpieces are often involved. With the continuous development of industrial production, higher requirements are placed on the processing accuracy and efficiency of disc workpieces.

[0003] However, currently, when processing disc workpieces with different diameters, many challenges are faced. Due to the different diameters of the discs, it is difficult to quickly and accurately achieve centering operations when placing them on the processing equipment. Traditional placement methods often rely on manual experience for adjustment, which is not only time-consuming and laborious, but also difficult to guarantee accuracy. In actual production, inaccurate centering will lead to deviations in subsequent shearing and curling operations, affecting product quality. For example, problems such as uneven edges and inconsistent dimensions may occur during shearing; uneven and insecure curling may occur during curling.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a shearing and curling equipment for metal product processing is provided, with the expectation of achieving a more practical value purpose. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment:

[0023] As shown in the attached Figure 1 to the attached Figure 4 shown:

[0024] The present invention provides a shearing and crimping device for metal product processing, including a shearing table 1 and a crimping table 2 slidably installed on a base 4. A central part of the top end of the base 4 is rotatably installed with an operating disc 3. A central part of the top end of the operating disc 3 is provided with a centering mechanism 5. The centering mechanism 5 includes a base 503 installed on the operating disc 3. A driving disc 501 is rotatably installed at the top end of the base 503. Arc-shaped driving bars 502 are equally angularly hinged to the bottom edge of the driving disc 501. The other ends of the four groups of arc-shaped driving bars 502 are all rotatably installed with centering rods 505. One ends of the four groups of centering rods 505 are detachably installed with contact heads 506. Outer walls of the bottom ends of the four groups of centering rods 505 are slidably connected to the base 503.

[0025] Among them, four groups of guide grooves 504 matching the outer walls of the centering rods 505 are equally angularly opened at the top end of the base 503. The centering rods 505 are slidably connected to the guide grooves 504, restricting the movement directions of the centering rods 505, preventing them from shifting or shaking during movement, and improving the stability of the entire centering mechanism 5.

[0026] Among them, four groups of sliding grooves 6 are equiangularly arranged on the working disk 3. Second racks 11 are slidably installed in the four groups of sliding grooves 6. One ends of the four second racks 11 are all installed with cutting knives 7. The tops of the four second racks 11 are all meshingly installed with gears 9. The tops of the gears 9 are meshingly installed with a first rack 8. The first rack 8 is fixedly installed at the bottom end of the centering rod 505. Connecting frames 10 are rotatably installed at the left and right ends of the gear 9. The two connecting frames 10 are both fixedly connected to the side wall of the base 503. When the centering rod 505 moves, through the transmission of the first rack 8, the gear 9 and the second rack 11, the cutting knife 7 is driven to retract. On the contrary, the cutting knife 7 is driven to extend. In this way, the annular debris can be cut, and the accumulation of debris on the working disk 3 can be avoided, which provides convenience for the staff.

[0027] Among them, a first motor 12 and a second motor 13 are fixedly installed in the middle of the bottom end of the base 4. The first motor 12 is used to drive the working disk 3 to rotate. A gear ring 15 is fixedly installed at the bottom end of the working disk 3. The gear ring 15 is meshingly installed with a driving gear 14. The driving gear 14 is fixedly sleeved on the outer wall of the output end of the second motor 13. The first motor 12 and the second motor 13 respectively control the rotation of the working disk 3 and the driving disk 501, so that the operator can independently adjust the motion parameters of the two components according to different processing requirements, improving the flexibility and adaptability of the equipment.

[0028] Among them, a T-shaped sliding groove is opened on one side of the top end of the centering rod 505. A T-shaped sliding block is arranged on one side of the contact head 506. The T-shaped sliding groove and the T-shaped sliding block are slidably connected. The contact surface of the contact head 506 is an arc-shaped contact surface, and the surface is covered with a soft and wear-resistant material. The connection method of the T-shaped sliding groove and the T-shaped sliding block enables the contact head 506 to be conveniently replaced, and a suitable contact head 506 can be selected according to the sizes and shapes of different metal products, improving the versatility of the equipment.

[0029] Among them, a control panel is installed on one side of the top end of the base 4. The control panel is electrically connected to the first motor 12 and the second motor 13 through wires respectively. The operator can intuitively control the operation of the first motor 12 and the second motor 13 through the control panel without complex mechanical adjustments, improving the convenience of operation.

[0030] The working principle of this embodiment: Start the second motor 13. The driving disk 501 rotates on the top end of the base 503. The arc-shaped driving strips 502 hinged at equal angles on the bottom edge of the driving disk 501 move as the driving disk 501 rotates. The arc-shaped driving strips 502 push the centering rod 505 rotatably installed therewith. The centering rod 505 slides in the guiding grooves 504 equiangularly opened on the top end of the base 503 and moves towards the center position of the working disk 3. The four centering rods 505 act simultaneously to perform an internal centering operation on the metal disk placed on the working disk 3.

[0031] When the centering rod 505 moves outward, the first rack 8 fixedly installed at the bottom end of the centering rod 505 moves accordingly. The first rack 8 drives the gear 9 meshed with it to rotate, and the gear 9 drives the second rack 11 to slide so as to retract the cutting tool 7. On the contrary, when the centering rod 505 moves inward, the cutting tool 7 installed at one end of the second rack 11 moves along with the sliding of the second rack 11, thereby performing a shearing operation on the metal chips.

[0032] The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
