As shown in fig. 1 to 4, the invention provides a hexagonal cold press for cold pressing outer hexagonal surfaces of steel pipes, which comprises a frame 1, a front plate 2, a middle plate 3, a rear plate 4 and a spiral pushing mechanism 5, wherein the front plate 2, the middle plate 3, the rear plate 4 and the spiral pushing mechanism are sequentially arranged on the frame 1; also comprises a piston cylinder 6; the front plate 2 is provided with a hexagonal pressing actuating mechanism 21, and the middle plate 3 is provided with a boosting taper sleeve 31; the hexagonal pressing actuating mechanism 21 comprises six wedge-shaped main modules 211 and twelve pressing blocks 212 for limiting the sliding range of the wedge-shaped main modules 211, a pressing head 213 is arranged at one end of each wedge-shaped main module 211, six faces, far away from the tail end of each wedge-shaped main module 211, of the six pressing heads 213 always enclose a regular hexahedron, the inner surface of the reinforcement taper sleeve 31 is an inclined face and is in contact with the wedge-shaped main modules 211 to form an inclined face loading structure, and the piston cylinder 6 is used for pushing the reinforcement taper sleeve 31 to move forwards or retract, so that the reinforcement taper sleeve 31 drives the wedge-shaped main modules 211 and the pressing heads 213. The six piston cylinders 6 correspond to the six wedge-shaped main modules 211, respectively. When the force-increasing taper sleeve 31 is pushed to move forwards, the force-increasing taper sleeve 31 drives the wedge-shaped main module 211 and the pressure head 213 to contract inwards; when the power cone 31 is pushed to retract, the power cone 31 releases the main wedge module 211 and the ram 213 to reset. The inner surface of the power-increasing taper sleeve 31 actually consists of a plurality of inclined surfaces with gradually decreasing diameters.
The hexagonal cold press is used for cold pressing the outer hexagon of the steel pipe; the steel pipe is inserted from the front end, namely the spiral pushing mechanism 5, is positioned by the ejector rod in the spiral pushing mechanism 5, and the position of the ejector rod positioning end can be adjusted by the spiral pushing mechanism 5 according to different hexagonal pressing position requirements.

Under the action of the force-increasing taper sleeve 31, the six wedge-shaped main modules 211 synchronously contract inwards to drive the pressing head 213 to press out a hexagon on the surface of the steel pipe. After the power cone 31 is retracted, the ram 213 and the main wedge module 211 are reset by the self-elasticity of the spring 214 and the tension of the tension spring 215. Each wedge-shaped main module 211 is limited in sliding range by two pressing pieces 212. And the die can be replaced to adapt to steel pipes with different diameters.
