Technical Field
[0001] This utility model belongs to the field of single-arm electro-hydraulic hammer technology, specifically relating to a hammerhead guide mechanism for a single-arm electro-hydraulic hammer. Background Technology
[0002] A forging hammer is a forging device that uses impact energy to cause plastic deformation of metal. The original steam-air forging hammer used steam or compressed air as power to achieve its forging function. It had low thermal efficiency, high energy consumption, and serious environmental pollution, making it outdated and obsolete. The electro-hydraulic hammer has the same performance as the original steam-air forging hammer and is superior in some aspects. Its installation is simple, maintaining the original frame, anvil, and infrastructure. The electro-hydraulic hammer performs well, does not change the operating habits of the original steam-air forging hammer, and can meet the forging process requirements of the original steam-air forging hammer, performing upsetting, drawing, rolling, pre-forging, final forging, and multi-station forging. It can achieve heavy striking, light striking, continuous striking, suspended hammer, and rapid retraction and emergency stop at any position. The striking energy can be adjusted appropriately by regulating the pneumatic and hydraulic pressure of the electro-hydraulic hammer, overcoming the inherent drawbacks of the original steam-air forging hammer's over-reliance on the steam boiler system. It can be started and used as long as there is electricity. The operation method is the same as the original steam-air forging hammer, but it is more flexible and convenient.
[0003] Currently, existing single-arm electro-hydraulic hammers typically raise the hammer head using a hydraulic telescopic rod and then quickly lower it to achieve forging. However, the forging hammer itself is quite heavy, so the range of movement during use is relatively large, making it difficult to ensure stable hammer head descent. Furthermore, the guiding mechanism of traditional single-arm electro-hydraulic hammers is often a simple guide rod, which is not very effective and prone to deviation, potentially affecting production quality. Utility Model Content
[0004] The purpose of this invention is to provide a hammerhead guiding mechanism for a single-arm electro-hydraulic hammer, aiming to solve the problem that existing single-arm electro-hydraulic hammers typically raise the hammerhead using a hydraulic telescopic rod and then quickly lower it to achieve forging. However, the forging hammer itself is heavy, so the range of movement during use is relatively large, making it difficult to ensure stable hammerhead descent. Traditional single-arm electro-hydraulic hammer guiding mechanisms are often simple guide rods, resulting in poor performance and easy deviation, which may affect production quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hammer head guide mechanism for a single-arm electro-hydraulic hammer, comprising a base, a connecting arm fixedly connected to the top of the base, one end of the connecting arm connected to a body, an anvil fixedly connected to the top of the base of the body, and a hammer head penetrating the bottom of the body;
[0006] The machine body has a first limiting block and a second limiting block symmetrically distributed inside. A guide rod is fixedly connected between the first limiting block and the second limiting block. Movable blocks are fixedly connected to the outer walls on both sides of the hammer head. Four first connecting seats are fixedly connected to the outer wall of the hammer head. Guide grooves are opened inside the four first connecting seats. Four fixed blocks are fixedly connected to the bottom of the machine body. One end of the four fixed blocks is rotatably connected to a guide pulley.
[0007] As a preferred embodiment of the hammerhead guiding mechanism of the single-arm electro-hydraulic hammer of this utility model, the four fixed blocks and guide pulleys are arranged in a ring.
[0008] In a preferred embodiment of the hammerhead guiding mechanism of a single-arm electro-hydraulic hammer according to this utility model, the guide pulley is located inside the guide groove.
[0009] As a preferred embodiment of the hammerhead guiding mechanism of the single-arm electro-hydraulic hammer of this utility model, the hammerhead can form a sliding connection structure with the machine body through a first connecting seat, a guide groove, a fixing block, and a guide pulley.
[0010] As a preferred embodiment of the hammerhead guiding mechanism of the single-arm electro-hydraulic hammer of this utility model, a second connecting seat is fixedly connected to the outer walls of both sides of the machine body, and a T-shaped sliding groove is opened inside the second connecting seat. A T-shaped slider is fixedly connected to one end of the movable block.
[0011] In a preferred embodiment of the hammerhead guide mechanism of this single-arm electro-hydraulic hammer, the second connecting seat is connected to the interior of the machine body.
[0012] As a preferred embodiment of the hammerhead guiding mechanism of the single-arm electro-hydraulic hammer of this utility model, a hydraulic pump is installed on the top of the machine body, and a hydraulic telescopic rod is installed on the top of the machine body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] With the arrangement of the movable block, the first connecting seat, the guide groove, the fixed block, and the guide pulley, when the hammer head descends along the guide rod, the guide pulleys distributed in a ring at the bottom of the machine body will slide along the guide groove inside the first connecting seat. At this time, during the descent, the bottom of the hammer head can be more stably forged on the workpiece under the guidance of the above structure, thereby further improving the stability of the hammer head.
[0015] With the second connecting seat, T-shaped slide groove, and T-shaped slider, when the movable blocks on both sides of the hammer head rise along the guide rod, the movable blocks will slide along the T-shaped slide groove under the action of the T-shaped slider, thereby further improving the stability of the hammer head when it rises.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a hammer head guide mechanism for a single-arm electro-hydraulic hammer, including a base 1, a connecting arm 2 fixedly connected to the top of the base 1, one end of the connecting arm 2 connected to a body 3, an anvil 4 fixedly connected to the top of the base 1 of the body 3, and a hammer head 5 penetrating through the bottom of the body 3.
[0025] The body 3 has a first limiting block 6 and a second limiting block 8 symmetrically distributed inside. A guide rod 7 is fixedly connected between the first limiting block 6 and the second limiting block 8. Movable blocks 9 are fixedly connected to the outer walls on both sides of the hammer head 5. Four first connecting seats 10 are fixedly connected to the outer wall of the hammer head 5. Guide grooves 11 are opened inside the four first connecting seats 10. Four fixed blocks 12 are fixedly connected to the bottom of the body 3. A guide pulley 13 is rotatably connected to one end of the four fixed blocks 12.
[0026] It should be noted that the anvil 4 is located directly below the hammer head 5.
[0027] Preferably, the four fixed blocks 12 and the guide pulley 13 are arranged in a ring, the guide pulley 13 is located inside the guide groove 11, and the hammer head 5 can form a sliding connection structure with the machine body 3 through the first connecting seat 10, the guide groove 11, the fixed blocks 12, and the guide pulley 13.
[0028] In practical use, through the arrangement of movable block 9, first connecting seat 10, guide slide 11, fixed block 12, and guide pulley 13, when the hammer head 5 descends along the guide rod 7, the guide pulley 13 distributed in a ring at the bottom of the machine body 3 will slide along the guide slide 11 inside the first connecting seat 10. At this time, during the descent process, the bottom end of the hammer head 5 can be more stably hammered on the workpiece under the guidance of the above structure, thereby further improving the stability of the hammer head 5.
[0029] Preferably, a second connecting seat 14 is fixedly connected to the outer walls on both sides of the body 3. A T-shaped slide groove 15 is opened inside the second connecting seat 14. A T-shaped slider 16 is fixedly connected to one end of the movable block 9. The second connecting seat 14 is connected to the interior of the body 3.
[0030] In practical use, through the setting of the second connecting seat 14, T-shaped slide 15, and T-shaped slider 16, when the movable blocks 9 on both sides of the hammer head 5 rise along the guide rod 7, the movable blocks 9 will slide along the T-shaped slide 15 under the action of the T-shaped slider 16, thereby further improving the stability of the hammer head 5 when it rises.

With the setting of the second connecting seat 14, T-shaped slide groove 15, and T-shaped slider 16, when the movable blocks 9 on both sides of the hammer head 5 rise along the guide rod 7, the movable blocks 9 will slide along the T-shaped slide groove 15 under the action of the T-shaped slider 16, thereby further improving the stability of the hammer head 5 when it rises. Then, when the hydraulic telescopic rod 18 drives the hammer head 5 connected to the output end to descend for forging, with the setting of the movable block 9, first connecting seat 10, guide slide groove 11, fixed block 12, and guide pulley 13, when the hammer head 5 descends along the guide rod 7, the guide pulley 13 distributed in a ring at the bottom of the machine body 3 will slide along the guide slide groove 11 inside the first connecting seat 10. At this time, during the descent, the bottom end of the hammer head 5 can be more stably forged on the workpiece under the guidance of the above structure, thereby further improving the stability of the hammer head 5.
