[0002] Steel production enterprises mainly produce various specifications of steel. Some products need to be forged during the production process. Forging hammer machines are generally used for forging. Existing forging hammer machines generally use hydraulic drive to drive the hammer head to hammer the material. They need to be equipped with a hydraulic station. Working in a high-temperature environment for a long time makes the hydraulic cylinder easy to be damaged. The maintenance cost is high and the maintenance takes up production time, which affects production efficiency. In addition, the whole equipment occupies a large area. Utility Model Content

[0016] Please see Figure 1-4 This embodiment is a high-speed impact forging hammer, including a fixed bracket 1. The fixed bracket 1 has a vertically arranged sliding cavity, with a slide rail 13 on the inner wall of the sliding cavity. A slider 6, slidably connected to the slide rail 13, is located inside the sliding cavity. An end plate is located at the top of the fixed bracket 1, and a compression spring 8 is installed between the end plate and the slider 6. A hammer rod 3 is installed at the bottom of the slider 6, extending downwards and having a hammer head 4 at its bottom end. A transverse through hole is located in the middle of the slider 6, and a sliding shaft 10 is installed within the through hole. The two sides of the fixed bracket 1 correspond to the sliding shaft 10. A vertically arranged elongated through hole 9 is provided. One end of the sliding shaft 10 extends outward from the elongated through hole 9 and has an inclined surface at its upper end. The upper end of the elongated through hole 9 has a blocking part that cooperates with the inclined surface. A return spring 7 is installed at the other end of the sliding shaft 10. A vertically arranged track 2 is provided on the outer side of the fixed bracket 1. A driving block 5 is slidably mounted on the track 2. A toggle pin 12 is provided at the end of the driving block 5 facing the inclined surface of the sliding shaft 10. The driving block 5 is connected to a lifting drive mechanism, which is used to drive the driving block 5 to move up and down along the track 2. Preferably, a stop 11 is provided at the bottom of the inner side of the sliding cavity. The stop 11 is used to limit the slider 6.

[0017] Preferably, the cross-section of the transverse through hole is rectangular, and the external cross-section of the sliding shaft 10 matches the through hole.

[0018] Preferably, the outer surface of the actuating pin 12 and the inclined surface of the sliding shaft 10 are both provided with a wear-resistant coating.

[0019] Preferably, the actuating pin 12 is cylindrical. Preferably, the blocking portion has an inclined surface that mates with the sliding shaft 10.

[0020] The working principle of this utility model is as follows: The lifting drive mechanism drives the drive block 5 to move along the track 2 so that the actuating pin 12 is located below the sliding shaft 10. Then, the drive block 5 is lifted upward. The drive block 5, through the sliding shaft 10, carries the slider 6, hammer rod 3, and hammer head 4 upward together. At the same time as it rises, the compression spring 8 is compressed until the inclined surface of the sliding shaft 10 touches the blocking part at the upper end of the elongated through hole 9. When the inclined surface receives downward resistance, the sliding shaft 10 is subjected to a part of the lateral thrust. This thrust is the component force generated by the inclined surface. The thrust causes the sliding shaft 10 to retract into the slider 6. As the sliding shaft 10 retracts, it disengages from the actuating pin 1. 2. The drive block 5 and the actuating pin 12 continue to move upward. At this time, the compression spring 8 releases its potential energy to push the slider 6 downward. At the same time, the slider 6, hammer rod 3 and hammer head 4 are subjected to gravity and impact the material at high speed once. Meanwhile, the return spring 7 causes the sliding shaft 10 to extend outward. Then, the lifting drive mechanism drives the drive block 5 to move downward. When the actuating pin 12 reaches the inclined surface of the sliding shaft 10, it continues to move downward and automatically pushes the sliding shaft 10 to retract inward. Then the actuating pin 12 moves to the bottom of the sliding shaft 10. At this time, the aforementioned lifting action can be repeated to perform a second hammering. By repeating this action, the material can be forged.

[0021] The lifting drive mechanism described in this utility model can take various forms. It can be a structure in which a motor drives a lead screw, and the lead screw is threadedly connected to the drive block 5. This structure is existing technology, so this utility model will not elaborate on it.

[0022] The lifting drive mechanism can also use a chain or sprocket. One section of the chain is fixedly connected to the drive block 5. The sprocket is driven by a motor to move the chain, thereby moving the drive block 5. This structure is also existing technology, so it will not be described in detail here.
