Description
Technical field
The present invention relates to a kind of drawing die, be specifically related to a kind of drawing die preventing tension failure.
Background technology
Along with progress and the expanding economy of society, machining product is more and more to be appeared in daily life, and drawn products is comparatively common in engineering goods, but the quality of some drawn products is lower, can not reach the desired instructions for use of people, and then the quality how improving drawn products becomes the first difficult problem that the producer will consider.
Because punch and die are in the process of matched moulds in prior art; holding pad is too large to the pressure of plate; usually can cause the fracture in drawn products face; after not external drawn products drawing and forming; when ejecting die by Lifting Device; drawn products outer surface and die inwall usually can be made to wear and tear, and then scratch the outer surface of drawn products, thus affect the quality of drawn products.
Not enough for the above of prior art, developer studies through great efforts, finally a kind of drawing die preventing tension failure of innovation and creation, this drawing die is provided with holding pad above die shoe, resilient sleeper-bearing is provided with between described die shoe and holding pad, described die shoe upper surface is fixed with punch, described punch is through resilient sleeper-bearing and holding pad, described holding pad upper surface is fixed with arcuation locating piece, when under the drive of stretching die at upper bolster slowly near stretching convex die time, first the plate be placed on holding pad is encountered, and then plate and holding pad slowly move down under the pressure of stretching die, the stretching convex die being fixed on die shoe upper surface is highlighted, thus stretching convex die and stretching die are coordinated, after stretching convex die and stretching die complete cooperation, stretching die is under the drive of upper bolster, slowly leave holding pad, simultaneously holding pad under the effect of resilient sleeper-bearing slowly on move, return to original position, thus drawn products is ejected from stretching convex die outer surface, owing to being provided with resilient sleeper-bearing below holding pad and stretching convex die is fixed on die shoe, avoid holding pad causes too greatly drawn products face in drawing process fracture to plate pressure, it also avoid Lifting Device when ejecting drawn products simultaneously, the scuffing caused, and then improve quality and the precision of drawn products.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, reasonable in design, the quality that improves drawn products and precision, easy to operate, be convenient to a kind of drawing die preventing tension failure promoted.
For solving above technical problem, the present invention comes to be realize by the following technical solutions: a kind of drawing die preventing tension failure, comprise upper bolster and the die shoe of corresponding setting, described upper bolster lower surface is provided with die fixed block, described die fixed block lower surface is fixed with stretching die, be provided with the stretching convex die corresponding with described stretching die above described die shoe, above described die shoe, be provided with holding pad, between described die shoe and holding pad, be provided with resilient sleeper-bearing.
Preferably, described upper bolster upper surface center is provided with die shank.
Preferably, described upper bolster lower surface is provided with guide pin bushing, and described die shoe is provided with guide pillar, and described guide pin bushing and guide pillar match, and quantity is respectively 4.
Preferably, described holding pad upper surface is provided with arcuation locating piece.
Preferably, the radian center of circle of described arcuation locating piece and stretching convex die are concentric circles.
Preferably, described stretching convex die bolt is fixed and die shoe upper surface.
By technique scheme, the invention has the beneficial effects as follows; The quality that structure is simple, reasonable in design, improve drawn products and precision, easy to operate, be convenient to a kind of drawing die preventing tension failure promoted.

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, the present invention is a kind of drawing die preventing tension failure, comprise upper bolster 2 and the die shoe 8 of corresponding setting, described upper bolster 2 lower surface is provided with die fixed block 3, described die fixed block 3 lower surface is fixed with stretching die 11, be provided with the stretching convex die 9 corresponding with described stretching die 11 above described die shoe 8, above described die shoe 8, be provided with holding pad 6, between described die shoe 8 and holding pad 6, be provided with resilient sleeper-bearing 7.
Described upper bolster 2 upper surface center is provided with die shank 1, described die shank 1 is fixedly connected with forcing press (not marking), described upper bolster 2 lower surface is provided with guide pin bushing 4 near four corner positions, described die shoe 8 upper surface is provided with the guide pillar 5 with described guide pin bushing 4 corresponding matching, by cooperatively interacting of guide pin bushing 4 and guide pillar 5, stretching convex die 9 and stretching die 11 more accurately can be made to match, thus further increase the quality of drawn products 12.
Holding pad 6 is provided with above described die shoe 8, described holding pad 6 upper surface is provided with arcuation locating piece 10, the radian center of circle and the stretching convex die 9 of described arcuation locating piece 10 are concentric circles, resilient sleeper-bearing 7 is provided with between described holding pad 6 and die shoe 8, described die shoe 8 upper surface is fixed with stretching convex die 9, described stretching convex die 9 is fixing with on die shoe 8 with bolt, when stretching die under the drive of upper bolster 2 slowly near stretching convex die time, first the plate be placed on holding pad 6 is encountered, and then plate and holding pad 6 slowly move down under the pressure of stretching die 11, the stretching convex die 9 being fixed on die shoe 8 upper surface is highlighted, thus stretching convex die 9 and stretching die 11 are coordinated, after stretching convex die 9 and stretching die 11 complete cooperation, stretching die 11 is under the drive of upper bolster 2, slowly leave holding pad 6, simultaneously holding pad 6 under the effect of resilient sleeper-bearing 7 slowly on move, return to original position, thus drawn products 12 is ejected from stretching convex die 9 outer surface, owing to being provided with resilient sleeper-bearing 7 below holding pad 6 and stretching convex die 9 is fixed on die shoe 8, avoid the fracture that holding pad 6 pairs of plate pressure cause too greatly drawn products 12 in drawing process, it also avoid Lifting Device when ejecting drawn products 12 simultaneously, the scuffing caused, and then improve quality and the precision of drawn products 12.
