Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of spiral pile pointed cone portion shaping equipment, wherein the Taper Pipe machine can be with steel tube end part machine-shaping solid-cone point.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of spiral pile pointed cone portion shaping equipment; Comprise many Taper Pipe machines that distribute side by side; The feed side of described many Taper Pipe machines is provided with a frame; Frame is provided with a plurality of feeding mechanical hands, a feed arrangement and a drawing mechanism, and described many Taper Pipe machines of described a plurality of feeding mechanical hands are corresponding one by one to be provided with; Said Taper Pipe machine, the main shaft that comprises housing on support, the support, rotates by motor-driven, installation mold and tup in the mold cavity of main shaft; Between tup and housing, be provided with roller groups, said tup comprises a plurality of tup pieces, and said mould is made up of at least three lobe mould blocks amalgamations; The amalgamation portion of every lobe mould blocks is triangular in shape; Top one side of amalgamation portion is provided with part conical surface groove, wherein, leaves the gap between the two side of the amalgamation portion of two adjacent lobe mould blocks; This gap is closed in the amalgamation center of described many lobes mould blocks, and the part conical surface groove on described many lobes mould blocks pieces together a complete taper hole; Described many lobes mould blocks respectively with the corresponding one by one setting of described a plurality of tup pieces, the inwall of the outer wall of every lobe mould blocks and tup piece offsets, mould blocks and tup piece thereof radially sliding along main shaft in the mold cavity of main shaft.
As preferably; The both sides of said mould blocks 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 blocks 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 said tup piece and can limit the limited step that the tup piece inwardly slides, limited step cooperates spacing with gib block.
As preferably, said mould is made up of the identical pintongs mould blocks amalgamation of structure, and said tup is provided with four gib blocks that cooperate with said mould and tup by constituting with corresponding four the tup pieces of mould in the mold cavity of main shaft.
As preferably, the outer wall of said tup piece is an arc surface; The radical of roller bearing is the integral multiple of the lobe number of mould blocks in the said mould in the said roller groups.
For the awl point processing and forming situation of short Taper Pipe, preferred said part conical surface groove is a tapering face; For the awl point processing and forming situation of long Taper Pipe, preferred said part conical surface groove is formed by the face rounding off of two different taperings, and is big near the tapering of the sharp face of awl.Help the moulding of solid-cone point like this.
The present invention is owing to adopted above technical scheme; The mould of Taper Pipe machine is made up of at least three lobe mould blocks amalgamations, and the amalgamation of two adjacent lobe mould blocks leaves the gap, thereby makes the part conical surface groove closing face on the mould blocks be positioned at the intersection of a plurality of mould blocks amalgamations; Because of adopting triangle in mould blocks amalgamation top; Make the mould blocks closing gap little, the active force that applies through tup so just can farthest act on tip, reaches the closed purpose of steel pipe tip.Especially be fit to big caliber (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 the big caliber steel pipe of prior art can't reach the solid-cone point in becoming the awl process a difficult problem.It is simple to have die change, long service life, and working (machining) efficiency is high, can realize through the replacing to mould the tapering of different length is carried out machining characteristics.
