Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] like Figure 1 and 2As shown, the stamping mechanism of the sealing device includes a mounting base 1, a first hydraulic mechanism 2, a second hydraulic mechanism 2, a stamping head 3, several cutting mechanisms, a control ring 402, and a control component 5. The top of the mounting base 1 is provided with a mounting platform, and both the first and second hydraulic mechanisms 2 are located at the bottom of the mounting platform. The stamping head 3, controlled by the first hydraulic mechanism 2, rises and falls to stamp the workpiece and form a cover 6. Several cutting mechanisms are respectively located inside the sidewalls of the stamping head 3. The cutting mechanisms are connected to the control ring 402; when the control ring 402 moves, it controls the cutting mechanisms to cut the sidewalls of the cover 6. The control component 5, controlled by the second hydraulic mechanism 2, descends to contact the control ring 402 and presses down on the control ring 402 to control the cutting mechanisms to perform cutting.

[0028] The top center of the stamping head 3 is connected to the bottom end of the movable rod 201 of the first hydraulic mechanism 2; the side wall of the stamping head 3 is provided with several movable grooves 301; such as Figure 5 The cover 6 structure shown has four baffles 601 on its side wall, so the number of movable slots 301 is preferably four. They are arranged on the side wall at equal intervals around the axis of the stamping head 3. The top of the stamping head 3 is provided with a control slot 302 around the movable rod 201. The four movable slots 301 are respectively connected to the control slots 302 through sliding holes 303.

[0029] The number of cutting mechanisms corresponds to the movable slots 301, preferably four. Each cutting mechanism includes a cutting blade 401, a sliding rod 403, and a connecting rod 405. The cutting blades 401 are rotatably disposed in the movable slots 301. When the cutting blades 401 rotate outward, they cut the sidewalls of the cover 6. The sliding rod 403 is slidably disposed in the sliding hole 303. One end of the sliding rod 403 is connected to the control ring 402, and the other end is hinged to the connecting rod 405. The other end of the connecting rod 405 is hinged to one side of the cutting blade 401. The control ring 402 is slidably disposed in the control slot 302. When the control ring 402 slides toward the movable slot 301, the sliding rod 403 slides downward along the sliding hole 303, pushing one end of the connecting rod 405 downward and the other end of the connecting rod 405 outward, causing the cutting blade 401 to rotate outward.

[0030] Specifically, the cutting tool 401 has a groove 406 on the side away from the stamping head 3, and a cutting edge is provided on the edge of the groove 406. When the cutting tool 401 rotates outward, the cutting edge contacts the side wall of the cover 6 and cuts it off. As the cutting tool 401 continues to rotate outward, the baffle 601 bends outward and takes shape. Then the cutting tool 401 resets, so that the cover 6 can be disengaged.

[0031] like Figure 3 As shown, in one embodiment, in order to avoid interference with the movement of the connecting rod 405, the sliding hole 303 is provided with a relief groove 304 at one end near the movable groove 301, which expands the movement space at the hinge of the connecting rod 405 and the sliding rod 403, and avoids the connecting rod 405 from being interfered with in motion.

[0032] When the control element 5 is driven by the second hydraulic mechanism 2 to disengage from the control ring 402, the control ring 402 needs to be able to reset in real time. Several springs 404, preferably four, are provided in the control groove 302, which are respectively wound around the slide rod 403, with one end connected to the bottom of the control ring 402 and the other end connected to the bottom of the control groove 302. When the control element 5 contacts the control ring 402 and presses down, the springs 404 are compressed. When the control element 5 disengages from the control ring 402, the springs 404 extend, causing the control ring 402 to reset.

[0033] Specifically, to prevent the control ring 402 from disengaging from the control groove 302, a retaining ring is provided at the edge of the top opening of the control groove 302, extending inward to restrict the control ring 402 from moving upward and disengaging from the control groove 302.

[0034] like Figure 4 As shown, in one embodiment, the control element 5 needs to be controlled separately from the control loop 402 to avoid motion interference caused by the simultaneous movement of the two, which would require a complex control system for regulation. Therefore, separating the control element 5 simplifies the control logic.

[0035] The control component 5 is vertically and flexibly mounted beside the stamping head 3, and includes a mounting plate 501 and a sleeve 502. The mounting plate 501 is connected to the bottom end of the movable rod 201 of the second hydraulic mechanism 2. The mounting plate 501 has a sleeve hole and is sleeved on the movable rod 201 of the first hydraulic mechanism 2 to limit the movement of the mounting plate 501 along the movable rod 201 of the first hydraulic mechanism 2. The sleeve 502 is located at the bottom sleeve hole of the mounting plate 501 and is sleeved on the movable rod 201 of the first hydraulic mechanism 2. The sleeve 502 is vertically and vertically corresponding to the control ring 402. The sleeve 502 is driven by the second hydraulic mechanism 2 to descend and contact the control ring 402. Continuing to descend will push the control ring 402 to slide along the control groove 302.

[0036] Specifically, in order to ensure the alignment accuracy between the sleeve 502 and the control ring 402, an alignment groove is provided around the top of the control ring 402. When the second hydraulic mechanism 2 controls the sleeve 502 to descend and fit against the control ring 402, the bottom edge of the sleeve 502 is embedded in the alignment groove.

[0037] The working principle of this embodiment is as follows:

[0038] In the stamping mechanism of this invention's sealing device, when stamping and cutting operations are required on the sealing cap 6, firstly, the first hydraulic mechanism 2 controls the stamping head 3 to descend and stamp the sealing cap 6. After stamping, the sealing cap 6 remains on the stamping head 3. At this time, the second hydraulic mechanism 2 controls the control component 5 to descend, so that the bottom edge of the sleeve 502 is embedded in the alignment groove of the control ring 402, and continues to press down the control ring 402; the control ring 402 slides along the control groove 302 toward the movable groove 301, the slide rod 403 slides down along the slide hole 303, pushing one end of the connecting rod 405 downward, and the other end of the connecting rod 405 pushes outward, while the cutting tool 401 rotates outward at the same time, so that the cutting edge cuts the side wall of the sealing cap 6, forming an outwardly protruding baffle 601;

[0039] After the cutting is completed, the second hydraulic mechanism 2 controls the control component 5 to rise, and the control ring 402 returns to the initial position under the action of the spring 404. The cutting tool 401 also rotates back to the initial position. Then, the first hydraulic mechanism 2 controls the stamping head 3 to rise, completing the entire stamping and cutting process.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
