Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of drawing die reducing Extrude Face fracture, comprise upper bolster 3 and the die shoe 9 of corresponding setting, described upper bolster 3 lower surface is fixed with stretching die block 4 and guide pin bushing 5, described stretching die block 4 lower surface is fixed with stretching die 15, and described stretching die 15 center is provided with push rod device;
The stretching punch-die 11 matched with described folding stretching die 15 is provided with above described die shoe 9, stretching punch-die fixed head 10 is provided with in the middle of described stretching punch-die 11 and die shoe 9, be provided with die pad 13 above described stretching punch-die fixed head 10, between described die pad 13 and stretching punch-die 11, be provided with liftout spring 12;
Described die shoe 9 upper surface is fixed with the guide pillar body cooperatively interacted with described guide pin bushing 5, and described guide pillar body mainly comprises guide pillar 7, be arranged on the back-moving spring 8 of guide pillar 7 outer surface and be fixed on the guide column sleeve 6 of back-moving spring 8 upper end.
Described upper bolster 3 upper surface is provided with die shank 2, and the pressure that forcing press is spread out of is delivered on upper bolster 3 smoothly, has ensured tensioning member 17 uniform force in shaping process.
Described push rod device forms primarily of push rod 1 and the pushing block 16 being fixed on push rod 1 lower end, described push rod 1 is through die shank 2, upper bolster 3 and stretching die block 4, and be connected with the pushing block 16 through stretching die 15, in matched moulds process, first the stretching die 15 be fixed on below stretching die block 4 encounters the plate being placed on die pad 13 upper surface, and then die pad 13 is moved downward, thus the stretching punch-die 11 being fixed on stretching convex-concave fixed head 10 upper surface matches with stretching die 15, when stretching punch-die 11 by bottom sheet metal stretching to stretching die 15 time, pushing block 16 makes it release bottom stretching die 15 under the promotion of push rod 1, and then stretched, upper bolster 3 drives stretching die 15 to move upward, die pad 13 is under the active force of liftout spring 12 simultaneously, the tensioning member 17 of drawing and forming is ejected from stretching punch-die 11, finally take off tensioning member 17, this kind of setting avoid stretch in drawing process too large to the pressure of plate between die 15 and stretching punch-die 11, the defects such as the slight crack caused, thus improve quality and the production efficiency of tensioning member 17.
Described back-moving spring 8 top connects guide column sleeve 6, described guide column sleeve 6 outer surface is the little of roll extrusion and most ball boss, guide column sleeve 6 is after each matched moulds completes, home position is returned under the elastic force effect of back-moving spring 8, because guide column sleeve 6 outer surface is provided with the little of roll extrusion and most ball boss, so the friction between decreasing in guide pin bushing 5 cooperatively interacts, and then improve its service life, simultaneously under the cooperatively interacting of guide pin bushing 5 and guide pillar body, improve the accuracy that tensioning member 17 is located in drawing process, thus improve the quality of tensioning member 17.
Described die pad 13 upper surface is fixed with side shelves material block 14, and then improves the positioning precision of plate at die pad 13 upper surface, thus improves the quality of production of bending part 17.
Beneficial effect of the present invention in sum; This kind of setting avoid drawing process stretching die and stretching convex die too large to the pressure of plate, and then easily in drawing process, there is the defects such as the slight crack of tensioning member, thus improve quality and the production efficiency of tensioning member.And then advantage of the present invention is; Reasonable in design, structure is simple, easy to operate, the fracture that reduces Extrude Face, improve tensioning member production efficiency, reduce production cost, be convenient to promote.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
