[0004] In the production process of seamless steel pipes, the raw materials need to be clamped and placed in the processing equipment. The clamping force of the current equipment depends entirely on the cylinder. During the clamping process, when the raw materials are too heavy or the surface is slippery, it is very easy to cause the clamping to be loose, so improvement is needed. Utility Model Content

[0028] The clamping mechanism 3 includes a first hydraulic telescopic cylinder 31, the bottom end of which is fixedly connected to a mounting plate 32, the bottom sides of the mounting plate 32 are slidably connected to a first clamping block 35 and a second clamping block 36, the outer sides of the first clamping block 35 and the second clamping block 36 are fixedly connected to sliding rods 33, the sliding rod 33 is slidably connected to a fixing frame 38 at one end away from the first clamping block 35 and the second clamping block 36, and the outer bottom of the fixing frame 38 is fixedly connected to a cylinder 37.

[0029] Through the provided clamping mechanism 3, when the cylinder 37 drives the first clamping block 35 and the second clamping block 36 to approach each other to clamp the seamless steel pipe raw material, due to the elasticity of the spring 34 itself, the clamping force between the first clamping block 35 and the second clamping block 36 can be further increased. The increase in the clamping force can effectively solve the problem of loose clamping when the raw material is too heavy or the surface is slippery during the clamping process.

[0030] The first hydraulic telescopic cylinder 31 can better adjust the upper and lower distances of the mounting plate 32 , thereby cooperating with the second hydraulic telescopic cylinder 22 to be applicable to loading of different raw materials in a wider range.

[0031] A sliding groove 321 is provided in the middle of the bottom of the mounting plate 32 , and sliding blocks 351 are fixedly connected to the tops of the first clamping block 35 and the second clamping block 36 .

The increase in clamping force can effectively solve the problem of loose clamping when the raw material is too heavy or the surface is slippery during the clamping process.

[0039] When the size of the seamless steel pipe raw material is limited, at this time, only by extending and shortening the second hydraulic telescopic cylinder 22, and with the cooperation of the slide rail 23 and the sliding seat 24, the height of the seamless steel pipe raw material clamped by the first clamping block 35 and the second clamping block 36 at the bottom of the bottom plate 25 can be adjusted, so as to further facilitate the loading and clamping in the production process.
