Abstract
The utility model discloses a drawing die ejecting mechanism, and relates to a die component. The drawing die ejecting mechanism comprises a lower die base, wherein a draw bar is arranged on the lower surface of the lower die base; external screw threads are formed at the upper end and the lower end of the draw bar respectively; the upper end of the draw bar is connected with the lower die base by the screw threads; the lower end of the draw bar is connected with nuts; a draw bar surface among the lower die base and the nuts is movably sleeved and connected with an upper supporting plate and a lower supporting plate; holddown springs are arranged between the upper supporting plate and the lower supporting plate; and ejection bars are arranged on the upper supporting plate, penetrate through the lower die base to be fixedly connected with a blank holder, and can move relative to the lower die base. The drawing die ejecting mechanism can provide enough blank holder pressure for a drawing die, avoids wrinkling of a drawing piece, improves the product surface quality, reduces a rejection rate, and is very convenient and practical.
Description
Technical field
The utility model relates to a kind of mold component, relates in particular to a kind of Drawing Die bullet and pushes up mechanism.
Background technology
Pull and stretch refers to the plate blank of definite shape is struck out the open hollow part of various shapes by Drawing Die, or further makes hollow object change a kind of cold stamping method for making of shape and size take the open hollow part as blank by pull and stretch.Can make the hollow object of flanged and other complicated shapes of Yuan Tong Xing ﹑ Qiu Xing ﹑ Zhui Xing ﹑ He Xing ﹑ Jie Ti Xing ﹑ by pull and stretch.Use existing Drawing Die to carry out pull and stretch and add man-hour, because pressure-pad-force is less, drawing part is usually wrinkling because of the material unstability, comprises wrinkling and non-straight wall drawing part sidewall sections wrinkling of flange deformation region, and the surface quality of pull and stretch is poor, and percent defective is high.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of Drawing Die bullet to push up mechanism, can provide enough pressure-pad-forces for Drawing Die, avoids drawing part wrinkling, has improved product surface quality, has reduced percent defective, and is very convenient and practical.
The technical solution of the utility model is: a kind of Drawing Die bullet pushes up mechanism, comprise die shoe, the die shoe lower surface is provided with pull bar, described pull bar upper/lower terminal even has respectively external screw thread, the pull bar upper end is threaded with die shoe, the lower end is connected with nut, and the pull bar surface activity between die shoe and nut is socketed with mounting plate and bottom plate, is provided with holddown spring between mounting plate and bottom plate; Be provided with push rod on mounting plate, push rod passes die shoe and is fixedly connected with holding pad, and push rod can move relative to die shoe.
As preferably, described die shoe adopts the Q235 steel to make, and pull bar adopts 45 steel to make.
As preferably, described holddown spring is two, is arranged at respectively pull bar both sides.
The beneficial effects of the utility model are: holding pad of the present utility model is connected with push rod, push rod is connected with mounting plate, when upper bolster descending, punch contacts with holding pad, holddown spring between mounting plate and bottom plate compresses along with moving down of upper bolster, and enough pressure-pad-forces can be provided, and avoids drawing part wrinkling, improve product surface quality, reduced percent defective.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, bottom plate; 2, holddown spring; 3, mounting plate; 4, die shoe; 5, push rod; 6, pull bar; 7, nut.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Fig. 1, a kind of Drawing Die bullet top mechanism comprises die shoe 4, and in the present embodiment, as preferably, described die shoe 4 adopts the Q235 steel to make, good combination property, long service life.Die shoe 4 lower surfaces are provided with pull bar 6, and as preferably, pull bar 6 adopts 45 steel to make.Described pull bar 6 upper/lower terminals even have respectively external screw thread, pull bar 6 upper ends are threaded with die shoe 4, the lower end is connected with nut 7, and pull bar 6 surface activities between die shoe 4 and nut 7 are socketed with mounting plate 3 and bottom plate 1, are provided with holddown spring 2 between mounting plate 3 and bottom plate 1; As preferably, described holddown spring 2 is two, is arranged at respectively pull bar 6 both sides, has increased pressure-plate-force of the present utility model.Be provided with push rod 5 on mounting plate 3, push rod 5 passes die shoe 4 and is fixedly connected with holding pad (not shown in FIG.), and push rod 5 can move relative to die shoe 4.
Claims (3)
