Technical field
The present invention relates to a kind of drawing die.Especially a kind of cam drawing die.
Background technology
Along with progress and the manufacturing development of society, machining finished product more and more enters into people's daily life, and tensioning member is the most common in engineering goods, for the reason that the use of people to tensioning member increases, thus the production quantity of tensioning member is just more and more, and then the difficult problem that the production efficiency of tensioning member has become the producer to consider.
Bottom drawing die, Lifting Device is provided with for enhancing productivity in prior art, and be exactly nothing but that elastic washer and spring produce screen resilience to eject tensioning member in Lifting Device, and in the process of stretching convex die and stretching die matched moulds, no matter that elastic washer or spring are when slowly shrinking downwards, plate active force is slowly increased, and then the stretching convex die active force moved downward slowly is increased, and then hinder punch and move downward, especially concerning some darker tensioning members, the active force of spring washer and spring is more obvious, and then have impact on the service life of drawing die.
Not enough for these of prior art, through the effort research that developer is long-term, finally have devised a kind of cam drawing die, this drawing die is fixed with cam Lifting Device at plate upper surface, described cam Lifting Device is by cam, push rod and ejection block formed, when stretching convex die and stretching die in the process at matched moulds, motor (not marking) band moving cam rotates, after described stretching convex die and stretching die complete matched moulds, stretching convex die slowly leaves stretching die, last die sinking completes, simultaneously ejection block ejects stretching die shaping tensioning member under the drive of push rod and cam, final driven by motor cam rotates a circle and gets back to original position, and then avoid tensioning member discontinuity when ejecting stretching die, also extend the service life of drawing die simultaneously.
Summary of the invention
The technical problem to be solved in the present invention there is provided that reasonable in design, structure is simple, the production efficiency that improve tensioning member, the service life extending drawing die, easy to operate, be convenient to a kind of cam drawing die of promoting.
For solving above technical problem, the present invention comes to be realize by the following technical solutions: a kind of cam drawing die, 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 stretching convex die, described die shoe upper surface is fixed with the stretching die corresponding with described stretching convex die, base plate is provided with below described die shoe, support is provided with between described base plate and die shoe, described plate upper surface is fixed with cam fixed block, and described cam fixed block side is fixed with cam Lifting Device.
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 cam Lifting Device is made up of cam, push rod and ejection block, and it is inner that described ejection block is arranged on stretching die.
Preferably, described push rod is axle with ejection block and cam and is connected.
Preferably, described ejection block shape is identical with tensioning member shape size.
By technique scheme, the invention has the beneficial effects as follows: reasonable in design, structure is simple, the production efficiency that improve tensioning member, the service life extending drawing die, easy to operate, be convenient to a kind of cam drawing die of promoting.
