Description
Technical field
The present invention relates to a kind of mechanical workpieces production, relate in particular to a kind of terminal box upper surface punching die.
Background technology
The terminal box that our factory is produced, the terminal box flitch after blanking, stretching and trimming technology processing, need to carry out punching processing to its upper surface.Use existing punching die and technology, the edge of going out hole is prone to burr, and surface becomes coarse because of impulse force; Punching for a long time, can cause the 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, the 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.
Summary of the invention
The problems referred to above that exist for solving prior art, the present invention has improved the structure of existing punching die, and to reduce the phenomenon of generation burr in punching edge in production process, the present invention adopts following technical scheme:
A kind of terminal box upper surface punching die, comprise cope match-plate pattern, punch retainer, guide pillar, piercing punch I, screw I, die shank, piercing punch II, screw II, lower bolster, screw III, screw IV, die, stripper, rubber, location-plate;
Punch retainer is fixed on the below of cope match-plate pattern by the screw II, die shank is arranged on the top of described cope match-plate pattern, the below of described cope match-plate pattern also is connected with the upper end of guide pillar, piercing punch I, piercing punch II respectively, and described piercing punch I, piercing punch II are through described punch retainer;
Guide hole on described guide pillar and location-plate and die coaxially is slidably matched, and described location-plate is positioned at the top of described die, by the screw IV, with described die, with lower bolster, is connected successively from top to bottom;
Described location-plate is sleeved on the outside of stripper;
Screw I one end connects described cope match-plate pattern, and the other end is embedded in stripper through rubber.
The die steel material of described a kind of terminal box 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, be heated to 900-950 ℃ of oil quenching after machined, finally 150-200 ℃ of tempering.
Each individual components that forms described a kind of terminal box upper surface punching die adopts Digit Control Machine Tool processing.
The invention has the beneficial effects as follows: the material selection microalloy Cr12MoV mould steel of punch and die, guaranteed die hardness, 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, 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 present invention have been improved, the gap of punch and die is remained between 0.01-0.02mm, adopt above technical scheme, can complete the punching technology of terminal box, and go out the edge in hole without burr, smooth surface; The stable structure design 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 terminal box.
