[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 A stamping device for processing small hardware accessories includes a hydraulic cylinder 1 and a punch head 2. A mounting rod 3 is fixedly installed at the bottom end of the driving shaft of the hydraulic cylinder 1. A mounting cavity is opened in the mounting rod 3. The surface of the mounting rod 3 is symmetrically opened with through holes. A mounting plate 4 is fixedly installed at the bottom of the mounting cavity. The left and right side walls of the mounting plate 4 are fixedly installed with triangular mounting blocks 5 through telescopic components. The telescopic components include two spring rods 11 fixedly installed on the side walls of the mounting plate 4. One end of the spring rod 11 away from the mounting plate 4 is fixedly connected to the surface of the mounting block 5. A locking block 6 is fixedly installed on the lower surface of the mounting block 5 through a connecting plate. A mounting groove is vertically opened on the upper surface of the punch head 2. The wall of the mounting groove is symmetrically opened with locking grooves 7 for inserting the locking block 6.

[0023] The surface of the mounting rod 3 is provided with a thread, and a ring-shaped slider 8 is threadedly sleeved, and a U-shaped connecting rod 9 is symmetrically fixedly installed on the side wall of the slider 8. A pressing ring 10 is slidably sleeved on the mounting rod 3, and the ends of the two connecting rods 9 away from the slider 8 are fixedly connected to the side wall of the pressing ring 10, and the lower surface of the pressing ring 10 is in sliding contact with the inclined surfaces of the two mounting blocks 5;

[0024] When the punch head 2 needs to be installed, first, the slider 8 is rotated to control the connecting rod 9 and the pressing ring 10 to move downward. During the downward movement of the pressing ring 10, the lower surface of the pressing ring 10 will press against the inclined surfaces of the two mounting blocks 5 respectively. Under the action of the inclined surface pressing, the two mounting blocks 5 will move laterally closer to each other. At this time, the multiple spring rods 11 will shrink, and the two locking blocks 6 will also move closer to each other. Then, the punch head 2 is aligned with the bottom end of the mounting rod 3 and inserted so that the bottom end of the mounting rod 3 is inserted into the mounting groove, and the punch head 2 is rotated so that the two locking grooves 7 are respectively in position with the two locking blocks 6. When the pressing ring 10 is controlled to move upward by rotating the slider 8, the pressing force of the pressing ring 10 on the two mounting blocks 5 gradually weakens, and the two mounting blocks 5 will respectively move and reset with the two locking blocks 6 under the elastic potential energy of the spring rod 11, and the two locking blocks 6 will be respectively inserted into the two locking grooves 7, thereby completing the locking of the mounting rod 3 and the punch head 2. When disassembly is required, it is only necessary to rotate the slider 8 to control the pressing ring 10 to move downward, so that the two mounting blocks 5 respectively bring the two locking blocks 6 close to each other until the two locking blocks 6 are respectively moved out of the two locking grooves 7, which is convenient and quick.

[0025] The bottom end of the mounting rod 3 and the bottom of the mounting groove are both fixedly mounted with magnets 12, and the magnetic poles of the two magnets 12 that are close to each other are opposite;

[0026] When the bottom end of the mounting rod 3 is inserted into the mounting groove, the two magnets 12 will attract each other, thereby having a simple locking effect on the punch head 2, thereby preventing the punch head 2 from falling directly when the two locking blocks 6 are removed from the two locking grooves 7 when the punch head 2 is disassembled.

[0027] A limiting assembly is provided on the lower surface of the hydraulic cylinder 1, and the limiting assembly is used to limit the downward movement of the slider 8. The limiting assembly includes an L-shaped limiting plate 13. A fixed block is symmetrically fixedly installed on the lower surface of the hydraulic cylinder 1. A rotating shaft 14 is installed horizontally and rotatably between the two fixed blocks. The limiting plate 13 is fixedly sleeved on the rotating shaft 14 and connected to the fixed block through an elastic component. The elastic component includes two torsion springs 15 sleeved on the rotating shaft 14. The two ends of the torsion spring 15 are fixedly connected to the limiting plate 13 and the fixed block respectively.

[0028] In the initial state, that is, the slider 8 is at the top and the pressing ring 10 no longer presses the two mounting blocks 5, the limiting plate 13 is in a vertical state under the elastic potential energy of the torsion spring 15, and its surface is against the lower surface of the slider 8, thereby limiting the downward movement of the slider 8, thereby preventing the slider 8 from rotating under the influence of the vibration force during the stamping process, thereby moving the pressing ring 10 downward, and causing the two locking blocks 6 to move out of the two locking grooves 7;

[0029] When the slider 8 needs to be controlled to move downward, the limiting plate 13 is first rotated so that the limiting plate 13 no longer contacts the slider 8, thereby releasing the restriction of the limiting plate 13 on the slider 8, and then the slider 8 is rotated to control its movement.

[0030] In the utility model, when the punch head 2 needs to be installed, first, the slider 8 is rotated to control the connecting rod 9 and the pressing ring 10 to move downward. During the downward movement of the pressing ring 10, the lower surface of the pressing ring 10 will be pressed against the inclined surfaces of the two mounting blocks 5 respectively. Under the action of the inclined surface pressing, the two mounting blocks 5 will move laterally closer to each other, and the two locking blocks 6 will also move closer to each other. Then, the punch head 2 is aligned with the bottom end of the mounting rod 3 and inserted, so that the bottom end of the mounting rod 3 is inserted into the mounting groove, and the punch head 2 is rotated to make the two locking grooves 7 correspond to the positions of the two locking blocks 6 respectively. At this time, the slider 8 is rotated to control the pressing ring 10 to move upward, and the pressing ring 10 is pressed against the two locking blocks 6. The pressing force exerted by the pressure ring 10 on the two mounting blocks 5 gradually weakens, and the two mounting blocks 5 will move and reset with the two locking blocks 6 respectively under the elastic potential energy of the telescopic component, and the two locking blocks 6 will be respectively inserted into the two locking grooves 7, thereby completing the locking of the mounting rod 3 and the punch head 2. When disassembly is required, it is only necessary to rotate the slider 8 to control the downward movement of the pressure ring 10 so that the two mounting blocks 5 respectively bring the two locking blocks 6 closer to each other until the two locking blocks 6 are respectively moved out of the two locking grooves 7. This is convenient and quick, avoids the tedious steps of using screw and nut fixings, and improves the work efficiency of replacing the punch head 2.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0032] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
