The stability during pre-installation can ensure the stability of the overall connection. For this purpose, we propose a highly stable electrolytic cell striking hammer head.
[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] The following is a combination of specific implementation cases and attached Figure 1 -Attached Figure 5 The present invention will be further described below, but the present invention is not limited to these embodiments.
[0028] A highly stable electrolytic cell striking hammer head comprises a hammer body 1 and a hammer core 2, wherein the hammer core 2 is embedded in the top of the hammer body 1 via a pre-tightening member 5. The hammer core 2 and the hammer body 1 are engaged with each other through an interference fit, and the pre-tightening member 5 ensures that the hammer core 2 is stably inserted into the hammer body 1. The pre-tightening member 5 prevents the hammer core 2 from moving in the opposite direction, ensuring the stability of the subsequent welding process of the hammer core 2 and the hammer body 1, thereby ensuring the overall stability of the hammer head and preventing it from falling off in the short term.
[0029] When the hammer head at the bottom of the hammer body 1 needs to be replaced, the hammer body 1 can be separated from the hammer core 2 by disassembling the workpiece, thereby reducing the cost of replacing the hammer head. A docking groove 3 is fixed to the top of the hammer core 2, and the docking groove 3 is used to connect with the movable end of the driving member.
[0030] A transmission joint 4 is fixed to the top of the hammer core 2. A docking slot 3 is defined at the top of the transmission joint 4. A preload seat 15 is evenly and slidably embedded in the inner wall of the docking slot 3. An umbrella-shaped memory element 6 is fitted into the bottom of the inner wall of the docking slot 3. This hollow, raised member fits snugly against the center of the inner bottom of the docking slot 3. When force is applied to the top of the umbrella-shaped memory element 6, its hollow inner wall completely fits against the inner bottom of the docking slot 3, causing the entire umbrella-shaped memory element 6 to deform. Power input elements 7 are evenly fixed to the circumferential edges of the umbrella-shaped memory element 6, and a linkage member connects the power input element 7 to the preload seat 15.
[0031] When connected to the hammer driver, the driver is typically a pneumatic cylinder. The active end of the driver moves toward the top of the umbrella-shaped memory member 6 within the docking groove 3. As the active end of the driver continues to move, the hollow inner wall of the bottom of the umbrella-shaped memory member 6 completely fits against the inner wall bottom of the docking groove 3. At this time, the circumferential edge of the umbrella-shaped memory member 6 moves circumferentially outward, causing the power input member 7 to move with the umbrella-shaped memory member 6. At this time, the preload seat 15 is moved from the inside of the storage groove 16 toward the outer wall of the active end of the driver through a linkage member. The preload seat 15 is clamped to the outer wall of the active end of the driver, thereby preloading the hammer on the active end of the driver. The hammer and driver are then fixed by a fixing member, preventing positional deviation during the connection operation and ensuring the stability of the hammer during operation. The fixing member used to preload the hammer and driver after the preload can be a floating shaft + universal joint connection, a metal clip, or other components.
[0032] Among them, the linkage component includes a transmission compartment 9 that is evenly fixed to the outer wall of the docking groove 3 in the circumferential direction. A transmission column 12 is slidingly provided on the inner wall of the transmission compartment 9. The transmission compartment 9 is fixedly installed on the outer wall of the docking groove 3. The transmission column 12 slides up and down on the inner wall of the transmission compartment 9. The bottom of the inner wall of the transmission compartment 9 and the bottom of the transmission column 12 can be connected by components such as springs and spring clips.
[0033] The position of the transmission column 12 can also be adjusted by a lever so that the lever rotates inside the transmission compartment 9, and the two ends of the tilted lever are respectively in contact with the power output member 8 and the power input member 7. The rotation of the lever causes the power output member 8 and the power input member 7 to move toward each other.
[0034] The sidewalls of the transmission column 12 are respectively formed with a power input slot 11 and a power output slot 10. The outer wall of the preload seat 15 is fixedly connected to the power output member 8, which extends into the interior of the power output slot 10. The power input member 7 extends into the interior of the power input slot 11. Both the power output slot 10 and the power input slot 11 have a longitudinal cross-section with a right-angled trapezoidal notch. The slope of the power output slot 10 is downward, while the slope of the power input slot 11 is upward.
[0035] As the shape of the umbrella-shaped memory member 6 changes, the edge of the umbrella-shaped memory member 6 drives the power input member 7 to pass through the side wall of the docking groove 3 and slide on the uphill slope of the power input groove 11. At this time, the transmission column 12 is forced to move upward. At this time, the power output groove 10 moves with the transmission column 12, so that the downhill slope of the power output groove 10 pushes the power output member 8 to move, so that the power output member 8 drives the preload seat 15 to move toward the inner cavity of the docking groove 3, thereby being clamped on the outer wall of the movable end of the driving member.
[0036] It is worth noting that the power take-off member 8 penetrates the sidewall of the docking slot 3 and slides within the through-hole. A guide block is fixedly attached to the outer wall of the power take-off member 8, and a guide groove is defined on the inner wall of the docking slot 3. The power take-off member 8 drives the guide block to slide against the inner wall of the guide groove. The guide groove is located in the middle of the through-hole to prevent the power take-off member 8 from escaping from the through-hole.
[0037] Furthermore, a limit slot 21 is defined at the bottom of the inner wall of the docking slot 3, and a limit post 22 is fixedly attached to the bottom inner wall of the umbrella-shaped memory element 6, extending into the interior of the limit slot 21. The limit post 22 slides longitudinally along the inner wall of the limit slot 21, thereby limiting the position of the umbrella-shaped memory element 6 and preventing it from shifting.
[0038] In addition, deformation stress grooves 13 are uniformly opened circumferentially at the edge of the umbrella-shaped memory member 6. Through the multiple circumferential deformation stress grooves 13, the umbrella-shaped memory member 6 can fit on the inner wall bottom of the docking groove 3 after being stressed.
[0039] Furthermore, the inner wall of the docking groove 3 is provided with a receiving groove 16 for hiding the pre-tightening seat 15. The inner wall of the docking groove 3 is provided with a receiving groove 16 having a shape corresponding to the pre-tightening seat 15. By hiding the pre-tightening seat 15, it is prevented from hindering the pre-connection process of the driving member.
[0040] A force-bearing plate 23, located within the docking slot 3, is fitted to the top of the umbrella-shaped memory element 6. Slide grooves 17 are evenly distributed along the inner wall of the docking slot 3. Sliders 18, which slide along the inner wall of the slide grooves 17, are fixed to the outer wall of the force-bearing plate 23. Sliders 18 are securely fastened to the bottom of the force-bearing plate 23. The force-bearing plate 23 prevents direct contact with the umbrella-shaped memory element 6 during connection, providing protection.
[0041] The pre-tightening member 5 includes a locking member 19 that is fixedly attached to the outer wall of the hammer core 2 at an angle. The inner wall of the hammer body 1 is evenly provided with anti-return grooves 20 that engage with the locking member 19. The locking member 19 is a sheet-like member. Since the hammer core 2 is approximately conical in shape, there is room for the bottom of the hammer core 2 to move when entering the interior of the hammer body 1. As the gap gradually decreases, the locking member 19 engages with the corresponding anti-return groove 20. Since the locking member 19 enters the interior of the hammer body 1 at an angle, as the gap between the hammer core 2 and the inner wall of the hammer body 1 decreases, the locking member 19 is embedded in the anti-return groove 20 and is located perpendicular to the ground. This prevents the hammer body 1 from separating from the hammer core 2.
[0042] Hammer body 1 is made of a nickel-chromium alloy infused with cobalt-based rare earth elements. This nickel-chromium alloy, combined with the addition of cobalt-based rare earth elements, utilizes a two-step special casting process. This overcomes the disadvantages of alloy steel, such as difficulty in welding and high cost. This significantly improves the hammer's wear resistance, impact resistance, and strength, significantly reducing electrolyte corrosion and adhesion. Furthermore, the hammer's service life can be adjusted based on the maintenance frequency of the shell-breaking cylinder, further reducing maintenance times and minimizing the occurrence of the electrolytic cell effect.
[0043] Since the electrolyzer hammers are made of durable material, they do not need to be replaced frequently.
