Specific embodiment
Invention is further described in detail combined with specific embodiments below.
Embodiment:
As shown in Fig. 2, a kind of inner face screw thread stamping continuous die of the invention, including flange pressing part 2, the spiral shell set gradually
Line forming part 3 and flange adjustment section 4.
As shown in Figure 3 and Figure 4, flange pressing part 2 includes the interior briquetting positioned at the cartridge type tray 21 of lower die and positioned at upper mold
22 and outer ram 23, interior briquetting 22 is located in outer ram 23 and can be through cartridge type tray 21, and cartridge type tray 21 is with facing out punching
The flat surface (not marking) of first 23 bottom surface.When molding, outer ram 23 and flat surface push down tablet periphery, prevent material from flowing.
After flange pressing part 2 molds, sleeve part 11 is taken shape between cartridge type tray 21 and outer ram 23, and interior briquetting 22 is by tablet center
Material further stretches expansion, then forms one the first of extension flange 12 ' of 11 inner edge of sleeve part with reversal deformation
Intermediate molded object 1 ', and the side blow processing part for extending flange 12 ' is exposed to outside sleeve part 11.
As shown in Figures 5 to 7, thread forming portion 3 includes being located at the lower tray 31 of lower die and being arranged around lower tray 31
If dry side forming blocks 33 and pressure head 34 and several inclined wedge formed punches 35 positioned at upper mold, pressure head 34 and lower tray 31 are opposite, side at
Type block 33 and inclined wedge formed punch 35 correspond, and the inside of side forming blocks 33 is equipped with the screw thread convex ridge 331 lower than lower 31 top surface of tray.
When thread forming portion 3 molds, pressure head 34 fixes 1 ' position of the first intermediate molded object with lower 31 split of tray, then inclined wedge formed punch
For 35 driving side forming blocks 33 toward inside split, screw thread convex ridge 331 will be in the portion being exposed to outside sleeve part 11 for extending flange 12 '
Divide upper extrusion 121 structure of inner face screw thread, forms the second intermediate molded object 1 ".
As shown in Fig. 1, Fig. 8 and Fig. 9, flange adjustment section 4 includes positioned at the interior tray 41 and external stripping plate 42 of lower die and position
Outer in upper mold rushes block 43 and interior briquetting 44, and interior tray 41 is opposite with interior briquetting 44, and external stripping plate 42 and the outer block 43 that rushes are opposite, outer de-
The top of plate 42 is cylindrical in shape and highest point is lower than the highest point of interior tray 41, and interior tray 41, which has, keeps away a part inner face screw thread 121
Accommodating chamber 411.When flange adjustment section 4 molds, interior tray 41 cooperates with interior briquetting 44 fixes the second intermediate molded object 1 ", interior
Face screw thread 121 is in accommodating chamber 411；Continue to mold, then the position of the shape and relative sleeve portion 11 that extend flange 12 ' can be sent out
Changing；Completely after molding, inner face screw thread 121 will be entirely retracted to 11 inside of sleeve part, form required vehicle oil filler
Part 1.
This progressive die overcomes the difficulty that inner face screw thread 121 is formed on the inside of product by three steps, and structure is simple, low
At the local continuity for realizing the processing of this product.
As shown in figure 3, the top of interior briquetting 22 is equipped with prismoid section 221.Interior briquetting 22 needs to expand the inside material of sheet
The extension flange 12 ' of Zhang Chengchang tubular, prismoid section 221 can play the role of correcting and avoid thrusting material.
As shown in figure 5, thread forming portion 3 further includes the de- material block 32 positioned at lower 31 side of tray, de- material block 32 is separate
There is internal thread groove 321 in the cambered surface of lower tray 31.De- material block 32 plays internal supporting role to material, and internal thread groove 321 is used
Keep away the material that position is squeezed and deformed by screw thread convex ridge 331, when die sinking, structure of the internal thread groove 321 to the second intermediate molded object 1 "
There is interference, under the action of de- material block 32 floats, the second intermediate molded object 1 " can be deviate from from lower die.
The start-stop position of the corresponding inner face screw thread 121 of internal thread groove 321.The start-stop position of inner face screw thread 121 is to extend flange
Structure is most complicated after 12 ' deformations one section, internal thread groove 321 is set to and can more swimmingly demould herein.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
