Description
Technical field
The utility model belongs to stamping equipment technical field, more particularly, to a kind of stamping die.
Background technology
Punching press is that depended on pressure machine and mold apply external force to plate, band, tubing and section bar etc., is allowed to generate plasticity change
Shape or separation, so as to obtain the workpiece of required shape and size（Stamping parts）Forming and machining method, stamping die be punching press life
Essential technological equipment, quality, production efficiency and the production cost of stamping parts etc. are produced, is had directly with mold design and manufacture
Connect relation.
When being punched out with stamping die to plate, sheet thickness difference requires the fit clearance size of punch and matrix
Difference, however existing stamping die is not easy to be punched out the plate of different-thickness processing due to the restriction of self structure.
Utility model content
The utility model is in order to overcome the deficiencies of the prior art and provide a kind of wide stamping die of use scope.
To achieve these goals, the utility model uses following technical scheme：A kind of stamping die, including upper mold under
Mould, the upper mold include upper mold seat and the punch-pin on the upper mold seat, and the lower die includes die holder, arranged on the lower die
The cavity plate slot of opening upwards and multiple cavity plates on seat are respectively equipped with a through hole on each cavity plate；The cavity plate slot and cavity plate it
Between be equipped with spline structure.The utility model can be placed in the cavity plate slot by setting cavity plate slot on die holder equipped with difference
The cavity plate of the through hole of bore, since the bore of through hole is different, so the fit clearance between punch-pin and multiple cavity plates is also different, into
And operation need to can be only punched out to the plate of different-thickness by the cavity plate replaced in cavity plate slot, use scope is wide；In addition
By setting spline structure, prevent cavity plate from rotating in punch process, ensure that being smoothed out for punch process.
The punch-pin includes the pressing part that can be embedded in the through hole, a diameter of 5mm of pressing part, the cavity plate number
For three, the through-hole diameter on three cavity plates is respectively 5.14-5.2mm, 5.28-5.34mm, 5.42-5.6mm；Due to three
The diameter of through hole is different on a cavity plate, so when three cavity plates coordinate respectively with punch-pin, the gap size between punch-pin
Difference, and then the hole of diameter 5mm can be punched out on the plate of different-thickness.
Further, the through-hole diameter on three cavity plates is respectively 5.18mm, 5.3mm, 5.5mm；Cooperation punch-pin makes
With the hole that diameter 5mm can be punched out on the plate of different-thickness.
Further, the spline structure include be arranged on the cavity plate groove sidewall on card division and on the cavity plate with
The matched card slot in card division；When cavity plate is placed in cavity plate slot, it can prevent cavity plate from existing by the cooperation of card division and card slot
It rotates in punch process, ensure that being smoothed out for punch process.
Further, the cavity plate groove bottom wall is equipped with blanking hole, and the die holder is equipped with one side and the cavity plate slot
The open slot being connected, the open slot opposite side are extended on the die holder side；What plate generated in punch process
Waste material can be discharged directly from blanking hole, and then prevent happening for through hole in blocking of waste materials cavity plate, 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 open slot is set
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 die holder is equipped with the first inclined surface；Incline arranged on described first the cavity plate channel opening part
On inclined-plane；The open slot one side is extended on first inclined surface；By setting the first inclined surface on 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 cavity plate is equipped with and matched second inclined surface in first inclined surface；When placing cavity plate,
Cavity plate is put into cavity plate slot again after only the first inclined surface on the second inclined-plane and die holder on cavity plate need to be alignd, so that it may
Ensure that card division can be caught in card slot, accelerate replacement speed.
Further, the upper mold seat 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 die holder,
And then it ensure that the planarization of plate.
In conclusion the utility model is by setting multiple cavity plates with different bore through holes, and set on die holder
The cavity plate slot of cavity plate can be placed by putting, and when punch-pin is respectively cooperating with multiple cavity plates, gap between the two is different, and then in punching
During operation, only need to change the cavity plate in cavity plate slot and achieve that the purpose being punched out to the plate of different-thickness, use scope
Extensively.
