Abstract
The utility model discloses a cone-forming mould for a cone pipe making machine. The cone-forming mould is formed by combing at least three pieces of mould blocks together. A combining part of each piece of the mould block is a triangle. One side of the top of each combing part is provided with a part cone-face groove. A gap is reserved between two side walls of the combining part between the two pieces of the adjacent mould blocks. Each gap is closed at the combining center of the multi-piece mould block. The part cone-face grooves on the multi-piece mould block are combined to form a whole cone hole. The cone-forming mould solves the difficult problem that large-tube-diameter steel tubes in the prior art can not achieve solid cone tips during cone-forming process. The cone-forming mould has the advantages of being simple to replace, long in service life, high in process efficiency, and capable of processing cone degrees of different lengths by means of replacement of the mould.
Description
Technical field
The utility model relates to a kind of one-tenth prod cast tool that is used for the Taper Pipe machine.
Background technology
Publication number is that the patent documentation of CN2663045Y discloses a kind of steel pipe Taper Pipe machine; Comprise housing on support, the support, by the main shaft of motor through the belt pulley transmission; Installation mold and tup in the mold cavity of main shaft are laid the combined type roller groups between spindle outer wall, tup outer wall and housing.But mould wherein is made up of two lobe mould blocks amalgamations up and down, because the amalgamation of two lobe mould blocks is the face contact; And part conical surface groove is formed on the amalgamation face; Existing technology can't guarantee the abundant applying of amalgamation face, so the part conical surface groove on two mould blocks can't be closed into a complete awl point, active force can't be applied to tip; So just can only steel pipe be processed into Taper Pipe, and can't be at tube end shaping solid awl point.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of the utility model provides a kind of one-tenth prod cast tool that is used for 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 utility model has adopted:
The one-tenth prod cast tool that is used for the Taper Pipe machine; Said mould is made up of at least three lobe mould blocks amalgamations, and the amalgamation portion of every lobe mould blocks is triangular in shape, and top one side of amalgamation portion is provided with part conical surface groove; Wherein, Leave 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.
As preferably, said mould is made up of the identical pintongs mould blocks amalgamation of structure.
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 utility model is owing to adopted above technical scheme; Mould 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.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done a detailed explanation.
Embodiment 1:
Like Fig. 1, Fig. 2, a kind of steel pipe Taper Pipe machine shown in Figure 3; Comprise housing 2 on support 1, the support 1, by the main shaft 3 of motor through the belt wheel transmission, installation mold 5 and tup 4 are provided with roller groups 6 in the mold cavity of main shaft 3 between tup 4 and housing 2; Said tup 4 comprises four tup pieces; Said mould 5 is made up of the identical pintongs mould blocks amalgamation of structure, and the amalgamation portion of every lobe mould blocks is triangular in shape, and top one side of amalgamation portion is provided with part conical surface groove; Wherein, Leave the gap between the two side 52 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 outer wall 54 of every lobe mould blocks offsets mould blocks 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 said mould blocks 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 blocks 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, is formed with on the said tup piece to limit the limited step that the tup piece inwardly slides, and limited step cooperates spacing with gib block 31.The radical of roller bearing is 3 times (12) of the lobe number of mould blocks in the said mould 5 in the said roller groups 6.The outer wall of said tup piece is an arc surface.Other part-structures of Taper Pipe machine can be the patent documentation of CN2663045Y referring to publication number.
For the awl point processing and forming situation of short Taper Pipe, like Fig. 4, Fig. 5, shown in Figure 6, the part conical surface groove of said mould blocks is a tapering face 51; For the awl point processing and forming situation of long Taper Pipe, like Fig. 7, Fig. 8, shown in Figure 9, the part conical surface groove of said mould blocks is formed by face 55,56 rounding ofves of two different taperings, and is big near the tapering of the sharp face of awl.
During work; Motor is through driving main shaft 3 rotations through belt pulley; Main shaft 3 drives tup and mould and produces centrifugal force in rotation process, because the contact-making surface of tup 4 and roller groups 6 is arc surfaces, when the outer wall arc surface of tup piece is between two roller bearings; Four mould blocks are opened under centrifugal action, and are 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 makes the pintongs mould closes, and was as shown in Figure 3.Under the rotatablely moving of main shaft, tup and roller bearing constantly collide, and make 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 point accordingly.
