Description
Technical field
The utility model belongs to blanking die field, specifically, relates to a kind of plate dovetail groove blanking die.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die.Whether blanking die structure is reasonable, advanced, directly has influence on the service life of production efficiency and blanking die itself and the aspect such as safety, convenience of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.Blanking die is mainly used in blanking and the punching of various sheet material, the working position of mould is the cutting edge of punch and matrix, withstand shocks during cutting edge work power, shearing force, bending force, and shear the strong friction power of material, thus the performance requirement to die point is mainly referred to the performance requirement of blanking die.According to the thickness of plate, cold punching die can be divided into Plate-Type Blanking Dies (thickness of slab≤1.5mm) and Blanking thick plank mould (thickness of slab >1.5mm) two kinds.For sheet die, require that die steel has high wearability; For Blanking thick plank mould, except requiring high wearability, compressive yield point, also should have high obdurability, rupture to prevent mould tipping.
A kind of plate part as shown in Figure 1, comprises multiple dovetail groove breach, and when processing this dovetail groove breach, need to adopt dovetail groove blanking die, traditional Dies ' Blanking precision is low, and poor stability, is easily damaged, and service life is short.
Chinese Patent Application No. 201410262868.9, the patent application document in publication date on August 20th, 2014, discloses a kind of diel.Described diel comprises: lower bolster; Guide plate, described guide plate is located on the upper surface of described lower bolster; Die, described die is located on described lower bolster; Guide pillar, described guide pillar is located on the upper surface of described lower bolster; Cope match-plate pattern; Punch press platen, described punch press platen is located on the lower surface of described cope match-plate pattern; Drift, described drift is located on described punch press platen; And guide pin bushing, described guide pin bushing is located on the lower surface of described cope match-plate pattern, and described guide pin bushing is relative with described guide pillar in the vertical direction.Disclosed in this patent application file, technical scheme structure is comparatively complicated, stamping-out plate dovetail groove can not be used for, and be set directly on lower bolster due to bore of the punch, guide plate position is unadjustable, once mold and punching head offsets, bore of the punch can not compensate adjustment to drift offset distance, and plate punching precision is reduced, to the high plate product of required precision then this mould can not continue to use, waste material and cost.
Chinese Patent Application No. 201210191243.9, the patent application document in publication date on October 3rd, 2012, discloses a kind of sheet metal component blanking die, belongs to sheet metal component technical field of processing equipment.Have the cope match-plate pattern in longitudinally arrangement and lower bolster, lower bolster is provided with the guide pillar of four arrangements that are square, and guide pillar top is passed cope match-plate pattern and fixed with nut, and on guide pillar, cover has spring; Cope match-plate pattern is fixed with stamping-out block, and stamping-out block top connects cylinder, and bottom is provided with the L shape edge of a knife, and cylinder and the L shape edge of a knife are placed in the upper and lower side of cope match-plate pattern respectively; Lower bolster is provided with square groove, and when cope match-plate pattern falls, the L shape edge of a knife stretches in square groove.This invention sheet metal component blanking die, novel in structural design, is controlled the whereabouts of cope match-plate pattern, realizes the blanking operation to sheet metal component by cylinder.Meanwhile, by guide pillar and spring, realize controlling the falling direction of cope match-plate pattern, thus improve the precision of punch press process.But this Dies ' Blanking precision is lower, the arranging of spring affects cope match-plate pattern and falls quickly and accurately, rub large simultaneously, easily makes burn failure or stuck oil cylinder when there is skew, the damage of build-up of pressure machine between guide pillar and cope match-plate pattern.
