Description
Technical field
The utility model relates to Stamping Die Technology field, is specifically related to a kind of diel.
Background technology
It is to be undertaken by the mode of machining mostly that the similar computor-keyboard of existing manufacture or keyboard holder are provided with the certain thickness flat part of having of multiple holes, undertaken by boring the modes such as milling, the advantage of this kind of mode is that the distortion of flat part is less, the machining accuracy of hole can be ensured preferably, but weak point is that working (machining) efficiency is low, and cost is very high.
For this reason, industry also has and proposes by the mode of the punching press above-mentioned hole that is shaped, it is normally placed on product material strip between the stripper plate and lower bolster of diel, and stripper plate top is provided with red needle fixed head and red needle backing plate, stripper plate and red needle fixed head or and red needle backing plate between be provided with Compress Spring.Compress stripper plate by this Compress Spring, thereby product material strip is fixed between stripper plate and lower bolster, and red needle is fixedly connected on upper bolster by red needle fixed head and red needle backing plate, after product material strip is placed on lower bolster, upper bolster starts to move downward, red needle moves downward and utilizes stripper plate pressuring spring to produce position difference and carry out die-cut to product material strip with upper bolster, the weak point of this kind of structure is: when punching press, stripper plate is depended merely on spring pressure compacted products material strip, because changing spring pressure, die-cut material deformation cause stripper plate pressure to put tight product material strip, so make and between stripper plate and lower bolster, have to a certain degree loosening, from causing product material strip not to be fixed on forcefully between stripper plate and lower bolster, so can cause red needle in the time of stamping products material strip because of the tight product material strip of stripper plate compacting, there is the angle of collapsing in the product material strip after punching press completes, torsional deformation, product material strip flatness is poor, the problems such as Stress non-homogeneity, and after punching press completes, red needle resets with red needle backing plate under the effect of spring restoring force, product material strip is produced to the pulling force of a trend stripper plate direction, after punching press is completed, product material strip is attached on stripper plate, need to manually go to be taken off not only waste of manpower, production efficiency is low, and has certain potential safety hazard.
Utility model content
The deficiency existing for prior art, the utility model provides the diel of the de-material of a kind of convenience.
For achieving the above object, the utility model provides following technical scheme: a kind of diel, comprise module and lower module, upper module comprises the red needle fixed head setting gradually from top to bottom, upper die plate, upper bolster, cope match-plate pattern and stripper plate, lower module comprises the lower bolster and the die shoe that set gradually from top to bottom, on red needle fixed head, be fixedly installed red needle, on lower bolster, offer punching, red needle is arranged in upper die plate successively, upper bolster, cope match-plate pattern and stripper plate and can punching press to punching, between red needle fixed head and upper bolster, be provided with back-moving spring, corresponding lower bolster one side of stripper plate offers chute, in chute, slip is provided with blanking bar, blanking pole pair is answered between the other end of lower bolster and red needle and is connected and be provided with guide groove, in guide groove, be hinged with seesaw, can butt and promotes blanking bar and the other end and the interlock of described red needle in one end of seesaw.
By adopting technique scheme, on lower bolster, offer punching, product material is placed on lower bolster, upper module is downward module one side shifting under the drive of pressing equipment, when in stripper plate and lower bolster laminating, stripper plate and lower bolster firmly clamp product material, and now red needle fixed head drives red needle to press down under the drive of pressing equipment, red needle is aimed at punching setting, and the product material on lower bolster is carried out to stamping-out; After stamping-out has moved, pressing equipment drives upper module to reset, now red needle fixed head return under the effect of back-moving spring, by red needle dorsad lower bolster one side detach, the product material after stamping-out completes has been attached on stripper plate; In this simultaneously, in the process detaching in red needle, red needle is lower bolster one side shifting dorsad, and drive seesaw to link, one end of the corresponding red needle of seesaw is with red needle lower bolster one side shifting dorsad, because seesaw is hinged in guide groove, therefore the other end of the corresponding red needle of seesaw promotes blanking bar towards lower bolster one side shifting extruding, make blanking bar in chute to lower bolster one Slideslip, and promote to be attached to the product material on stripper plate, make its Automatic-falling, avoid manually-operated danger, effectively improved operating efficiency, and de-material is convenient.
The utility model is further set to, and on the sidewall of described blanking bar, is extended with baffle plate, and the corresponding baffle position of chute is provided with groove, between corresponding lower bolster one side of baffle plate and groove, is provided with back-moving spring.
