Technical field
The present invention relates to a kind of drawing die.Especially a kind of drawing die driving punch and determine punch.
Background technology
Along with progress and the manufacturing development of society, machining finished product more and more enters into the daily life of engineering goods consumer, and tensioning member is the most common, and then the quality problems solving tensioning member can the difficult problem that will consider of the producer.
And in prior art drawing die when stretching multiaspect part; usually there will be several plane and obtain force-extension simultaneously; often cause some problems such as fracture and Extrude Face discontinuity of Extrude Face; tensioning member production efficiency can be caused to reduce for these problems and serviceability undesirable, and then great worries have been with to the user of tensioning member.
Not enough for these of prior art, developer studies through long-term effort, finally have devised a kind of drawing die driving punch and determine punch, this drawing die is designed with a kind of mould structure with double-convex-mold, when stretching multiaspect, can come to stretch one by one by this double-convex-mold structure, avoid the problem allowing multiple Extrude Face simultaneously receive tensile force, also eliminate and use multiple drawing die to stretch, the problem that the location of causing is inaccurate, then a kind of birth of drawing die driving punch and determine punch, the Quality advance of multiaspect tensioning member is played a significantly greater role, tensioning member consumer daily life is provided a great convenience.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of reasonable in design, structure is simple, the fracture that effectively reduces multiaspect tensioning member, reduce cost, be convenient to a kind of drawing die driving punch and determine punch of promoting.
For solving above technical problem, the present invention comes to be realize by the following technical solutions: a kind of drawing die driving punch and determine punch, comprise upper bolster and the die shoe of corresponding setting, described upper bolster lower surface is provided with punch fixed block, described punch fixed block lower surface is fixed with determines punch, describedly determine punch centre bit and be equipped with dynamic punch, described dynamic punch upper surface is fixedly connected with by push rod, described die shoe upper surface is provided with determines punch and die corresponding to dynamic punch with described, and described die shoe lower surface center is provided with Lifting Device.
Preferably, described upper bolster upper surface center is provided with push rod, and described push rod runs through upper bolster and is fixedly connected with dynamic punch.
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 4 right.
Preferably, described punch retainer center is provided with dynamic punch chamber, and described dynamic punch is arranged on dynamic punch chamber and determines inside punch.
Preferably, described determine punch and dynamic punch complete closed after be M shape.
Preferably, described Lifting Device is made up of elastic washer and kicker, and described kicker is fixed on elastic washer upper surface, and through die shoe and die.
By technique scheme, the invention has the beneficial effects as follows: a kind of inclined-plane drawing die that reasonable in design, structure simply, effectively prevents tensioning member fracture, improves the inclined-plane depth of parallelism of tensioning member, is convenient to popularization.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
