Description

Technical Field

[0001] The utility model belongs to the technical field of cutting auxiliary equipment, in particular to a mechanical clamp for cutting a steel pipe. Background Art

[0002] The application range of steel pipes is very wide. Steel pipes are used in construction, machinery manufacturing, automobile manufacturing, medical and food industries. The finished steel pipes are long, so they need to be cut. During the cutting process, the steel pipes are prevented from moving and causing harm to the health of the cutting operators. Usually, clamps are needed to fix them.

[0003] Existing document CN216607417U-A mechanical clamp for steel pipe cutting includes a base, the top of which is movably provided with a first support frame and a second support frame, and the side wall of the second support frame is penetrated with an opening. When the new clamp is used to assist the cutting machine to complete the fixation of the steel pipe before cutting, the steel pipe can be passed through the opening of the side wall of the second support frame to pass through the auxiliary clamp assembly and connect with the inner support clamp assembly. The staff can control the handle assembly to make each T-shaped support block move to complete the fixation of the inner wall of one side of the steel pipe. At the same time, the other side of the outer wall of the steel pipe will be fixed by each clamping block in the fixing ring. The double fixing method can not only improve the fixing stability of the steel pipe before cutting, but also effectively improve the overall efficiency of steel pipe cutting. However, it still has the following disadvantages in actual use:

[0004] 1. The above-mentioned mechanical clamp for cutting steel pipes supports the auxiliary clamp assembly and the inner support clamp assembly through the first support frame and the second support frame, and supports the steel pipe through the inner support clamp assembly. However, the heights of the first support frame and the second support frame are fixed. For thicker steel pipes, they are too close to the upper surface of the base after being fixed, which is not conducive to cutting;

[0005] 2. The above-mentioned mechanical clamp for cutting steel pipes adjusts the distance between the first support frame and the second support frame through the first movable block, the second movable block and the positioning bolt. Therefore, each adjustment requires adjusting the positions of the first movable block and the second movable block, resulting in complicated operation steps and inconvenience in use.
