Description
Technical field
The utility model relates to a kind of mechanical workpieces to be produced, and relates in particular to a kind of fan guard upper surface punching die.
Background technology
The fan guard workpiece that our factory is produced, the fan guard flitch after blanking, stretching and trimming technology processing, need to carry out punching processing to its upper surface, once goes out the elliposoidal hole of a plurality of gradual changes, and a circular port is gone out in center.In existing punching technology, time processing density is large, the irregular hole in graphical-set, and the edge in hole is prone to burr, and surface becomes coarse because of impulse force; Punching for a long time, can cause punch cutting edge to be worn, when the degree of wear is larger, also can make the workpiece of producing produce burr, surface flatness reduces, for guaranteeing product quality, punch cutting edge needs plain grinding to put the first edge on a knife or a pair of scissors, and punch cutting edge plain grinding puts the first edge on a knife or a pair of scissors, strengthened workman's working strength, lose the production time, reduced operating efficiency, increased entreprise cost.
Utility model content
The problems referred to above that exist for solving prior art, the utility model has improved the structure of existing punching die, and to reduce the phenomenon of generation burr in punching edge in production process, the utility model adopts following technical scheme:
A fan guard upper surface punching die, comprises cope match-plate pattern, screw I, backing plate, punch retainer, die shank, screw II, pin I, guide pin bushing, guide pillar, stripper, pin II, piercing punch, screw III, die, lower bolster, rubber;
Backing plate and punch retainer are anchored on the below of cope match-plate pattern from top to bottom successively by screw I, screw II and pin I, and the top of described cope match-plate pattern is provided with die shank;
Guide pin bushing is fixed on the below of described cope match-plate pattern, and guide pillar is fixed on the top of lower bolster, and described guide pillar coordinates with guide pin bushing relative sliding;
One end of piercing punch is fixed on the below of described punch retainer, and its other end is through stripper;
Die is by the top that is anchored on described lower bolster of pin II and screw III;
Between described punch retainer and stripper, be provided with rubber, screw I through in the stripper described in rubber embedding, is connected described punch retainer from top to bottom with stripper.
The die steel material of described a kind of fan guard upper surface punching die is selected microalloy Cr12MoV mould steel, the Technology for Heating Processing of mould steel is: after hot rolling, be heated to 1050 ?1150 ℃ carry out solution treatment, being as cold as soon 600 ℃ proceeds in 400-700 ℃ of stove and makes it isothermal transformation, after machined, be heated to 900-950 ℃ of oil quenching, finally 150-200 ℃ of tempering.
Each individual components that forms described a kind of fan guard upper surface punching die adopts Digit Control Machine Tool processing.
The beneficial effects of the utility model are: the material selection microalloy Cr12MoV mould steel of punch and die, guaranteed die hardness, and mould steel adopts above-mentioned Technology for Heating Processing, has reduced carbon emission, and quenching degree can be enhanced about more than once; The independent workpiece of Digit Control Machine Tool processing mold, has improved the precision of independent workpiece; Independent workpiece high accuracy processing and overall construction design optimization, reasonability and the stability in the monolateral gap of the utility model have been improved, the gap of punch and die is remained between 0.01-0.02mm, adopt above technical scheme, can once go out the highdensity irregular hole of fan guard upper surface, and punching edge is without burr, smooth surface; Stable structure design makes, and has extended the service time of a cutting edge plain grinding, has reduced the plain grinding frequency of punch cutting edge, has improved production efficiency and the production precision of fan guard.
Accompanying drawing explanation
