Description
Technical field
The utility model belongs to stamping equipment technical field, more particularly, to a kind of diel.
Background technology
Punching press is that depended on pressure machine and mold apply external force to plank, band, tubing and proximate matter etc., is allowed to generate plasticity change
Shape or separation, to obtain the workpiece of required shape and size（Stamping parts）Forming and machining method, diel be punching
Pressure produces essential technological equipment, quality, production efficiency and production cost of stamping parts etc., with mold design and manufacture
There is direct relation.
When being punched out to plate with diel, sheet thickness difference requires the fit clearance size of punch and matrix
Difference, however existing diel is not only not easy to carry out the plate of different-thickness due to the restriction of self structure
Punching processing, and in punching operation on blocking of waste materials cavity plate also easy to happen the case where through-hole, and then influence punching operation
Progress.
Utility model content
The utility model for overcome the deficiencies in the prior art, provide it is a kind of can anti-blocking of waste materials diel.
To achieve the goals above, the utility model uses following technical scheme：A kind of diel, including upper mold

It replaces.
Further, the cavity plate groove bottom wall is equipped with blanking hole, and the lower die holder is equipped with side and the cavity plate slot
The open slot being connected, the open slot other side extend on the lower die holder side；What plate generated in punch process
Waste material can directly be discharged from blanking hole, and then the case where preventing through-hole in blocking of waste materials cavity plate occurs, and ensure that punching
Journey is smoothed out,, only need to be by a straight-bar insertion opening slot, then when cavity plate to be replaced additionally by setting open slot
Straight-bar is pressed by lever principle, one end of straight-bar can eject cavity plate out of cavity plate slot, and then convenient for the replacement of cavity plate.
Further, the lower die holder is equipped with the first inclined surface；Incline set on described first cavity plate channel opening part
On inclined-plane；The open slot side extends on first inclined surface；By the way that the first inclined surface is arranged on lower die holder, and it is recessed
The opening portion of die cavity upper end is arranged on first inclined-plane, so when cavity plate is placed in cavity plate slot, the upper end of cavity plate
It is protruding on first inclined-plane so that replacing cavity plate becomes more convenient.
Further, the upper die holder is equipped with a briquetting that can be moved up and down；Plate is after punching technology, in hole week
Easily there is rough region in the region enclosed, and can be flattened these uneven regions by the cooperation of briquetting and lower die holder,
And then it ensure that the planarization of plate.
In conclusion the utility model is by being arranged multiple cavity plates with different bore through-holes, and set on lower die holder
The cavity plate slot of cavity plate can be placed by setting, and in punching operation, the cavity plate only needed to change in cavity plate slot can be to the plate of different-thickness
It is punched out processing, use scope is wide, can eject the waste material being trapped in through-hole in through-hole additionally by elastic pressing structure,
