As preferably, the both sides of described mould piece and tup piece thereof are provided with gib block, gib block is fixed on the main shaft, thereby the two side of the guide part of mould piece cooperates the slip of can leading with the gib block of its both sides, thereby the two side of tup piece cooperates the slip of can leading with the gib block of its both sides, be formed with on the described tup piece and can limit the limited step that the tup piece inwardly slides, limited step cooperates spacing with gib block.
As preferably, described mould is made of the identical pintongs mould piece amalgamation of structure, and described tup is made of four tup pieces corresponding with mould, is provided with four gib blocks that cooperate with described mould and tup in the mold cavity of main shaft.
As preferably, the outer wall of described tup piece is arc surface; The radical of roller bearing is the integral multiple of the lobe number of mould piece in the described mould in the described roller groups.
For the cone point processing and forming situation of short Taper Pipe, preferred described part conical surface groove is a tapering face; For the cone point processing and forming situation of long Taper Pipe, preferred described part conical surface groove is formed by the face rounding off of two different taperings, and is large near the tapering of the sharp face of cone.Be conducive to like this moulding of solid-cone point.
The utility model is owing to having adopted above technical scheme, mould is made of at least three lobe mould piece amalgamations, and the amalgamation of two adjacent lobe mould pieces leaves the gap, thereby so that the part conical surface groove closing face on the mould piece is positioned at the intersection of a plurality of mould piece amalgamation, because adopting triangle in mould piece amalgamation top, make mould piece closing gap little, the active force that applies by tup so just can farthest act on tip, reaches the closed purpose of steel pipe tip.Especially be fit to Large Diameter Pipeline (external diameter Φ 50 and more than, thickness of pipe wall 3mm and more than) the tip machine-shaping solid-cone point of steel pipe, solved prior art Large Diameter Pipeline steel pipe can't reach the solid-cone point in becoming the cone process a difficult problem.Have die change simple, long service life, working (machining) efficiency is high, can realize by the replacing to mould the characteristics that the tapering of different length is processed.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
Such as Fig. 1, Fig. 2, a kind of steel-pipe conical-tube machine shown in Figure 3, comprise support 1, housing 2 on the support 1, by the main shaft 3 of motor through the belt wheel transmission, installation mold 5 and tup 4 in the mold cavity of main shaft 3, between tup 4 and housing 2, be provided with roller groups 6, described tup 4 comprises four tup pieces, described mould 5 is made of the identical pintongs mould piece amalgamation of structure, the amalgamation section of every lobe mould piece is triangular in shape, top one side of amalgamation section arranges part conical surface groove, wherein, leave the gap between the two side 52 of the amalgamation section of two adjacent lobe mould pieces, this gap is closed in the amalgamation center of described many lobes mould piece, and the part conical surface groove on described many lobes mould piece pieces together a complete taper hole; Described many lobes mould piece respectively with the one by one corresponding setting of described a plurality of tup pieces, the outer wall 54 of every lobe mould piece offsets mould piece and tup piece thereof radially sliding along main shaft in the mold cavity of main shaft 3 with the inwall of tup piece.The both sides of described mould piece and tup piece thereof are provided with gib block 31, four gib blocks 31 are fixed on the main shaft 3, thereby the two side 53 of the guide part of mould piece cooperates the slip of can leading with the gib block 31 of its both sides, thereby the two side of tup piece cooperates the slip of can leading with the gib block of its both sides 31, be formed with on the described tup piece and can limit the limited step that the tup piece inwardly slides, limited step cooperates spacing with gib block 31.The radical of roller bearing is 3 times (12) of the lobe number of mould piece in the described mould 5 in the described roller groups 6.The outer wall of described tup piece is arc surface.Other part-structures of conical-tube machine can be the patent documentation of CN2663045Y referring to publication number.
For the cone point processing and forming situation of short Taper Pipe, such as Fig. 4, Fig. 5, shown in Figure 6, the part conical surface groove of described mould piece is a tapering face 51; For the cone point processing and forming situation of long Taper Pipe, such as Fig. 7, Fig. 8, shown in Figure 9, the part conical surface groove of described mould piece is formed by face 55,56 rounding ofves of two different taperings, and is large near the tapering of the sharp face of cone.
During work, motor is by driving main shaft 3 rotations through belt pulley, main shaft 3 drives tup in rotation process and mould produces centrifugal force, because tup 4 is arc surfaces with the contact-making surface of roller groups 6, when the outer wall arc surface of tup piece is between two roller bearings, four mould pieces open under centrifugal action, as shown in Figure 2; When the outer wall cambered surface of tup piece headed on the roller bearing of roller groups, tup collision mould made the pintongs mould closed, as shown in Figure 3.Under the rotatablely moving of main shaft, tup and roller bearing constantly collide, so that mould continuous high-speed impact workpiece in motion process, make workpiece (cylinder hollow steel pipe) produce plastic deformation and become with the mould taper hole that sets and bore accordingly point.
