[0002] The wedge-shaped tension clamp is a type of tension clamp for overhead transmission line hardware. It uses the characteristic of the wedge-shaped structure that it becomes tighter as it is pulled, and clamps the conductor when subjected to external force. It has been widely used in recent years because of its convenient installation and the characteristics of not breaking the conductor. The side sliding cover is a key component in the wedge-shaped tension clamp structure to achieve the closed installation of the outer shell and the sliding of the inner wedge.

[0003] Currently, commonly used wedge-shaped tension clamps are all made of aluminum alloy, and the side sliding cover is generally manufactured using an aluminum alloy extrusion process. Since the use scope of the aluminum alloy wedge-shaped tension clamp has certain limitations, in order to adapt to more usage scenarios, the utility model proposes a step-by-step forming forging die for the side sliding cover of a carbon steel wedge-shaped tension clamp.

[0006] A further technical solution is that the left fixing plate and the right fixing plate are both fixed to the base plate by bolts.

[0007] A further technical solution is that four threaded holes are provided at the bottom of the left fixing plate and the bottom of the right fixing plate.

[0008] A further technical solution is that the four threaded holes are evenly arranged.

[0009] A further technical solution is that the left fixing plate and the right fixing plate are symmetrically distributed on the bottom plate.

[0010] A further technical solution is that the left protrusion and the right protrusion are arranged opposite to each other.

[0011] The utility model has the following beneficial effects: the utility model performs secondary molding on the wedge-shaped tension wire clamp, and through the secondary molding, the parts which originally can only be manufactured by the casting process are forged, and the forging performance is better.
