Abstract
The utility model discloses a radial pressure applying reducing die of a flexible metal tube, comprising an upper die plate fixed on pressure equipment and a lower die plate fixed on a rack, wherein the upper die plate is driven to move up and down by the pressure equipment; an upper die is fixed on the upper die plate; the lower surface of the upper die is provided with an upper die cavity; a position on a lower die is fixed on the lower die plate corresponding to the upper die; the upper surface of the lower die is provided with a lower die cavity; the upper die cavity and the lower die cavity are fastened to form a horizontal reducing cavity which corresponds to the reduced outer profile of a processed pipe in shape and size; the processed pipe is sheathed on a core rod which is arranged horizontally; one end of the core rod corresponds to the shape and the size of the reduced inner profile of the processed pipe; and the core rod sheathed with the processed pipe is arranged in the reduced cavity. Compared with the prior art, the radial pressure applying reducing die of the flexible metal tube changes the original axial stress of the processed pipe into radial stress by changing the structure of the reducing die, thus reducing the processing difficulty of a mold and demolding difficulty of products, and prolonging the service life of the mold.
Description
Technical field the utility model relates to a kind of metal tube processing mold, relates in particular to a kind of flexible metal conduit reducing die of radially exerting pressure.
Background technology is present, carries out the reducing processed mould for the strong flexible metal conduit of plasticity such as brass and generally adopts the axial pressure reducing die.As shown in Figure 1, the counterdie 01 of this axial pressure reducing die is provided with profile and the corresponding die cavities 02 of size vertically disposed and reducing 3 outlines, processed tubing 5 is sheathed in the die cavity 02 that places counterdie 01 on the plug 6, patrix 03 moves downward under the driving of press device 8, promote the processed tubing 5 of plug 6 extruding, processed tubing 5 is out of shape under the effect of axial compressive force and forms reducing.
The shortcoming of this processing mold is:
1, because the metal pipe material wall thickness is thinner, the manufacture difficulty of mould is big;
2, press device need adopt the large-tonnage hydraulic press;
3, be radially expanded demoulding difficulty after metal tube is squeezed;
4, be subjected to metal tube expansion extruding, counterdie radially ftractures easily.
The summary of the invention the purpose of this utility model provides that a kind of mould manufacture difficulty is little, the demoulding easily and the flexible metal conduit of the long service life reducing die of radially exerting pressure.
For achieving the above object, the utility model comprises cope match-plate pattern that is fixed on the press device and the lower bolster that is fixed on the frame, described cope match-plate pattern is driven by press device and moves up and down, be fixed with patrix on the cope match-plate pattern, this patrix lower surface is provided with upper cavity, with the corresponding fixed-site of patrix counterdie is arranged on the lower bolster, this counterdie upper surface is provided with lower mode cavity, and upper cavity and lower mode cavity fasten formation and the shape of the outline of processed tubing reducing and the reducing die cavity of big or small corresponding horizontal direction; Processed tubing is sheathed on the plug, plug one end shape and size are corresponding with size with the shape of the interior profile of processed tubing reducing, plug one end that is arranged with processed tubing places in the lower mode cavity, on the baffle plate that the other end of plug is fixed in lower bolster is fixedlyed connected, and the plug horizontal positioned.
Adopt structure of the present utility model, the reducing of tubing is that the difficulty of processing of upper die and lower die reduces greatly by the die cavity co-extruded moulding of upper die and lower die.Since tubing be subjected to force direction for radially, being radially expanded after having avoided tubing to be squeezed effectively, thus the demoulding after the processing is more prone to.In addition, because the minimizing that is radially expanded and the common moulding of upper and lower mould, the possibility that mould is extruded cracking reduces, and has improved the service life of reducing die.Baffle plate can be fixed in plug in the die cavity in process, prevents processed tubing because be squeezed and breaks away from die cavity, has guaranteed the precision of product processing.
In sum, the utility model compared with prior art, the utility model is by the change to reducing die structure, the axially loaded that processed pipe fitting is original, change radial force into, thereby reduced the difficulty of Mould Machining difficulty and product stripping, prolonged die life.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a cutaway view of the present utility model.
The specific embodiment as shown in Figure 2, the utility model comprises cope match-plate pattern 1 that is fixed on the press device 8 and the lower bolster 2 that is fixed on the frame 9, described cope match-plate pattern 1 is driven by press device 8 and moves up and down, be fixed with patrix 11 on the cope match-plate pattern 1, these patrix 11 lower surfaces are provided with upper cavity 12, with patrix 11 corresponding fixed-site counterdie 21 is arranged on the lower bolster 2, these counterdie 21 upper surfaces are provided with lower mode cavity 22, and upper cavity 12 fastens with lower mode cavity 22 and forms and the shape of processed tubing reducing 3 outlines 31 and the reducing die cavity 4 of big or small corresponding horizontal direction; Processed tubing 5 is sheathed on the plug 6, the shape of plug 6 one ends 61 and size are corresponding with size with the shape of the interior profile 32 of processed tubing reducing 3, plug 6 one ends 61 that are arranged with processed tubing 5 place in the lower mode cavity 22, the other end 62 of plug 6 is fixed on the baffle plate 7 of fixedlying connected with lower bolster 2, plug 6 horizontal positioned.Processed tubing 5 is the similarly stronger softer metals of plasticity such as brass, red copper, in the die cavity of bolster through once the extruding after, reducing 3 cross sections that processed tubing 5 forms may be on-circular cross-sections such as ellipse, revolve processed tubing 5 and turn 90 degrees this moment, carries out just can making processed pipe material reducing 3 cross sections form circle after the secondary extrusion in die cavity again.
