Description

Technical Field

[0001] The utility model belongs to the technical field of forging equipment, and in particular relates to an electric hammer for forging processing. Background Art

[0002] The electric hydraulic hammer delivers hydraulic oil to the pressure cylinder through an electric pump to generate forging pressure. Compared with traditional pneumatic hammers or mechanical hammers, the electric hydraulic hammer usually has higher precision and control performance. Since the hydraulic system can provide a smoother and continuous force output, it is easier to achieve multiple impacts during the forging process, and to a certain extent, the vibration and noise generated by the impact are reduced;

[0003] When an existing electro-hydraulic hammer is processing and forging a workpiece, a pad needs to be placed between the workpiece and the hammer head. The pad can disperse the impact force transmitted by the hammer head and make it act evenly on the surface of the workpiece, which helps to reduce local stress concentration and avoid cracks or deformation of the workpiece. Since the pad is placed directly on the workpiece, it is necessary to ensure that it corresponds to the hammer head. The pad will vibrate and displace every time the hammer head impacts, which can easily affect the correspondence between the pad and the hammer head. At the same time, in order to protect the workpiece during each punching, the hammer head needs to ensure that the pad is placed in correspondence with the impact position of the hammer head. Therefore, when the hammer head impacts the workpiece multiple times, the position of the pad is adjusted multiple times, and the alignment time is long, which affects the processing efficiency of the workpiece.

[0018] In this embodiment: the electro-hydraulic hammer body 1 is used to perform hammering processing on the workpiece. The hammer part on the electro-hydraulic hammer body 1 can impact the workpiece, so as to have an impact forging effect on the workpiece. The electro-hydraulic hammer body 1 is supported by the support frame 2, so that the electro-hydraulic hammer body 1 is supported by the support frame 2 at a certain height, and the support frame 2 is fixed on the support plate 21, ensuring that the electro-hydraulic hammer body 1 is firmly supported by the support frame 2, so that it can firmly forge the workpiece placed on the support block 3 fixedly connected to one side of the support plate 21. The support block 3 corresponds vertically to the hammer part on the electro-hydraulic hammer body 1, so that when the workpiece is placed at the center of the support block 3, it can ensure that the workpiece is subjected to vertical pressure from the hammer part, thereby avoiding deviation and causing the workpiece to be deformed. The forging quality of the workpiece is affected. After the workpiece is placed on the support block 3, it can be above the support block 3 through the limit frame 31, and the limit frame 31 can be driven by the driving telescopic rod 33 fixedly connected to the outside of the support block 3, so that the limit frame 31 can be pushed to move up and down, so that the limit frame 31 can make the limit rod 34 slidably connected on the limit frame 31 correspond to the middle position of the workpiece under the upward push of the driving telescopic rod 33. At this time, the limit rod 34 can slide on the limit frame 31, and the outer wall of the workpiece can be supported by one end of the limit rod 34, so that the limit rod 34 in three directions can support the workpiece, and one end of the limit rod 34 can be adjusted to be in The length of the limit frame 31 is so that the staff can quickly reset the position of the workpiece after it is displaced, thereby improving the resetting of the workpiece position when the hammer continuously impacts the workpiece, thereby improving the forging efficiency of the workpiece.

The spring 351 can generate an inward pulling force on one end of the outer plate 342, so that the limit rod 34 can be displaced into the limit frame 31, and the adjusting rod 36 threadedly connected on the outer plate 342 can also be rotated to adjust the position of the adjusting rod 36 on the outer plate 342, and one end of the adjusting rod 36 can move the limit rod 34 to the center position in the limit frame 31. The limit rod 36 can be rotated in advance to adjust the length of the inward displacement of the limit rod 34, so as to facilitate the limiting of the position of the workpiece. At the same time, the spring 351 can make way for the limit rod 34 to move the workpiece when the workpiece is displaced, so as to avoid direct hard contact and affect the service life of the device. When resetting is required, it is judged by observing whether one end of the adjusting rod 36 is in contact with the outer wall of the workpiece. At the same time, the docking slide 22 opened on the support frame 2 can install the slide plate 23, and the push rod 24 slidably connected to the slide plate 23 can be located behind the support frame 2, so that the push rod 24 can support the workpiece at one side close to the support frame 2 under the push of external action, so that its symmetrical side is in contact with one end of the limit rod 34.
