Description
Technical field
The present invention relates to a kind of cold punching die, use the method for quick die change core on punch press to produce different types of product
Product.
Background technology
Along with extensively application and the development of stamping technology, every profession and trade all be unable to do without diel, especially automobile, electrical equipment,
Motor, instrument and article of everyday use industry, the speed etc. of its product quality, production efficiency, production cost and model change, all
Depending greatly on diel, and mould structure is the soul of diel, it not only determines the function of mould,
Also determine the cost of mould and manufacturing cycle and the safety of operation simultaneously, and can guarantee that every technology of product parts is wanted
Ask.Either simplex process engineering mould will slowly step down from the stage of history.Use disposal molding progressive die will be popularized rapidly and take
For the former.
Summary of the invention
In order to solve above-mentioned technical problem, it is provided that a kind of new construction and be capable of multiple operation, the mould of multiple effect,
The present invention devises techniques below scheme, it is an object of the invention to provide first paragraph and produces two kinds of products, second segment punching, beats
Convex, cut off, flange, the progressive die that molding multiple operation merges into a single whole.This progressive die structure is novel, and manufacturing process is simple, can carry
High efficiency, it is ensured that product quality, reduces production cost.
The technical scheme is that a kind of progressive die producing multiple product, be also a kind of to utilize circular hole in ring type
Waste material produces different types of product, then carries out circular ring type flange raising progressive die.This mould includes upper die component, lower module
Part, upper die component include upper bolster, upper padding plate, train wheel bridge, baffle plate, stripper plate, cut-out molding raising drift, whole flatness fiber crops
Click and enter block, guide pillar, the outer limited post of upper mold etc., lower mold include lower bolster (die), lower bolster, lower backboard, die shoe, bottom seat pad,
The outer limited post of bottom plate, lower mold alignment pin, lower mold guide pad, lower mold etc..It is characterized in that:
Upper mold dowel pin essence fixes upper bolster and train wheel bridge, and upper mold screw connects upper bolster, upper padding plate and train wheel bridge, and upper mold is led
Post and train wheel bridge guide pillar hole interference fits, with stripper plate matched in clearance, cut off molding public affairs and be fixed on train wheel bridge, and pin hole transition is joined
Close.Because of molding, cutting off must thermoplasticity be good, hardness is high, good toughness, so all punchings (i.e. the lower mold edge of a knife enters block), cutting into
Type public affairs material is high-speed alloy cold work die steel (SKH-9), and upper mold working part precision is high, easy to assembly.
Lower mold guide pad coordinates with lower bolster guide pad interporal lacuna, and lower mold screw pushes down lower mold guide pad, lower mold alignment pin
With lower mold dowel hole matched in clearance, lower mold alignment pin and lower bolster dowel hole matched in clearance, lower mold dowel pin essence connects lower mold
Plate, lower bolster, lower backboard and die shoe, lower mold screw connects lower bolster and die shoe, and lower mold screw connects die shoe and underlay
Block.Lower mold all enter block be designed as quick-disassembly structure, facilitate mold repair, improve work efficiency.
Upper mold guide pillar and guide pillar hole (70) matched in clearance on lower bolster, play essence guide effect, reach the smooth and easy work of upper and lower mould
Making, upper mold cuts off molding public affairs with the lower mold edge of a knife with matched in clearance, reaches high accuracy and cuts off molding, it is ensured that product quality, meets visitor
Family requirement.Upper and lower mould limited post is connected by screw, and it plays spacing, to ensure die life effect.
