[0028] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0029] Example 1

[0030] See Figure 1 The present embodiment provides a forging hammer, which includes a forging hammer body 100. The forging hammer body 100 includes a frame 101. An air hammer 102 is provided at the frame 101. The air hammer 102 has a hammer head 1021 that can move up and down; an anvil 103 is provided below the hammer head 1021, and rotating rods 110 are provided on both sides of the anvil 103. A mounting shell 120 is provided at the front end of the hammer head 1021. A lifting plate 121 is slidably provided on the mounting shell 120. Matching rods 1211 are formed at both ends of the lifting plate 121. The rotating rod 110 is used to match with the matching rod 1211.

[0031] According to the solution provided in this embodiment, the anvil 103 can hold the metal substrate, the air hammer 102 can drive the hammer head 1021 to hit the metal substrate in the vertical direction, thereby realizing the forging of the metal substrate, and the rotation of the rotating rod 110 can lift the lifting plate 121, thereby better realizing the protection of the user.

[0032] That is, when using the forging hammer, the metal substrate to be forged is placed on the anvil 103, the hammer head 1021 of the air hammer 102 is controlled to descend, and at the same time the rotating rod 110 is rotated to lift the lifting plate 121, thereby better preventing the user facing the anvil 103 from being hit by sparks flying during forging; after the hammer head 1021 rises, the lifting plate 121 falls, and the user can use tools to adjust the metal substrate.

[0033] Through the above structure, it is possible to better prevent sparks generated by forging from hitting the user, and it is convenient for the user to adjust the position of the metal substrate.

[0034] See Figure 1-4 Two mounting posts 2021a are formed on the side wall of the hammer head 1021, and a telescopic assembly 130 is provided below the mounting post 2021a. The telescopic assembly 130 includes an assembly housing 231, one end of the assembly housing 231 is threadedly engaged with the mounting post 2021a, and the other end forms a telescopic hole 3311, a telescopic rod 232 is slidably provided at the telescopic hole 3311, and a mating end 4321 slidably engaged with the assembly housing 231 is formed at one end of the telescopic rod 232, and a spring 233 is provided between the mating end 4321 and the mounting post 2021a, and the spring 233 is used to resist the tendency of the telescopic rod 232 to move away from the mounting post 2021a.

[0035] Among them, by setting the telescopic rod 232, the rotation of the rotating rod 110 can be realized. When the hammer head 1021 descends, the telescopic rod 232 hits the rotating rod 110 to deflect the rotating rod 110, thereby raising the lifting plate 121 to protect the user; by setting the spring 233, it is possible to match metal substrates of different heights.

[0036] It is understandable that the hammer head 1021 descends at a faster speed, so the impact force is greater, so the telescopic plate can continue to rise to a height sufficient to shield the user under the action of inertia.

[0037] See Figure 1 A support platform 1011 formed integrally with the frame 101 is provided below the anvil board 103. The support platform 1011 is fixedly connected to the anvil board 103, and a plurality of reinforcing ribs 1012 are formed at intervals at the lower end of the support platform 1011.

[0038] Among them, by providing the support platform 1011, the installation of the cutting board 103 is preferably achieved, and by providing the reinforcing ribs 1012, the strength of the support platform 1011 can be preferably improved.

[0039] See Figure 1 and 5 A support seat 140 is provided on both sides of the support platform 1011. The support seat 140 includes a mating flange 543 fixedly matched with the support platform 1011 and a support shaft 544 formed at the mating flange 543. The support shaft 544 is used to rotatably cooperate with the rotating rod 110. A mating shaft neck 545 is formed at one end of the support shaft 544 away from the mating flange 543. A locking nut 241 is provided at the mating shaft neck 545. The locking nut 241 is threadedly engaged with the mating shaft neck 545.

[0040] The support seat 140 can support the rotating rod 110 , and the locking nut 241 can keep the rotating rod 110 located at the matching shaft neck 545 , thereby preferably achieving the installation of the rotating rod 110 .

[0041] See Figure 1-6A ball bearing 242 is provided at the matching shaft neck 545 , a matching hole 611 is formed correspondingly at the rotating rod 110 , the matching hole 611 is matched with the rolling bearing, and matching plates 612 are formed at both ends of the rotating rod 110 .

[0042] Among them, by providing the ball bearing 242, the rotation resistance of the rotating rod 110 is preferably reduced, which facilitates the rotating rod 110 to transfer the pressure to the matching rod 1211, thereby lifting the lifting plate 121.

[0043] See Figure 1 and 2 A limiting platform 2013 integrally formed with the supporting platform 1011 is disposed at the lower end of the supporting seat 140 , and two buffer rubber pads 2014 are spaced apart at the limiting platform 2013 .

[0044] The limiting platform 2013 is provided to preferably limit the rotation range of the rotating rod 110 , and the buffer rubber pad 2014 is provided to preferably reduce the damage to the rotating rod 110 caused by impact, thereby increasing the service life of the rotating rod 110 .

A first limit block 7212 is formed at the lower end of the lifting plate 121, and a second limit block 8201 is correspondingly formed at the upper end of the mounting groove.

[0046] Among them, by providing the first limiting block 7212 and the second limiting block 8201, the limiting of the lifting plate 121 is preferably achieved, so that the lifting plate 121 can always be located in the installation groove.

[0047] See Figure 1 A plurality of pulleys are provided in the mounting groove, and the plurality of pulleys are used for rolling cooperation with the lifting plate 121.

[0048] By providing a plurality of pulleys, the friction between the mounting groove and the lifting plate 121 is reduced, thereby increasing the lifting speed of the lifting plate 121 .

[0049] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
