Description
Technical field
The utility model relates to a kind of pick forging piece molding die, belongs to precision metal technical field of forging.
Background technology
Pick is the cutter of mining machinery cutting coal and rock, and in coal mining industry, consumption is very large.Pick forging is applied in the vitals on coal mine development machine drum, umbrella shape forging, wherein umbrella-shaped portion is shaping more difficult, in where umbrella-shaped portion forming process, radial extruding force is larger, the production environment of shaping mould is more severe, the failure mode of shaping mould is the radial nose shape ftractureing this forging is taper, bar portion diameter is little, be applicable to machining, but machining consumptive material is many, cost increases, and stock-removing efficiency is low, be unfavorable for producing in enormous quantities, being in great demand of pick forging, utilizes machining far can not meet the need of market.
Existing pick forging shaping moudle structure adopts bilayer combination mode structure, the prestressing force increasing shaping mould improves die life, the inner ring of existing pick forging shaping moudle structure can cold forging die material, outer ring adopts 40Cr material, by combined die structure for inner ring provides prestressing force, when carrying out cold extrusion, radial compression power suffered by mould just in time can offset a part with prestressing force, thus the radial compression power reduced suffered by mould, improve the working environment of mould, but this structure consumptive material is many, cost is comparatively large, is beneficial to production in enormous quantities.
Utility model content
The purpose of this utility model is: for the defect of prior art, propose a kind of pick forging piece molding die, this mould not only further increases prestressing force, decrease the risk of shaping mould radial direction cracking, improve the life-span of mould greatly, and consumptive material is few, cost is low, is beneficial to production in enormous quantities.
The technical scheme that the utility model adopts is: a kind of pick forging piece molding die, comprise pressure block one, upper pressure block two, downforce block one and downforce block two, upper pressure block one is positioned at the top of downforce block one, upper pressure block two is positioned at the top of downforce block two, the side of upper pressure block one is provided with centre circle, adjacently with upper centre circle be provided with Upper Die-sleeve, the opposite side of upper pressure block one is adjacent with downforce block one is provided with upper punch, wherein the side of downforce block two is provided with lower centre circle, and the opposite side of downforce block two is provided with compensation fill block.
In the utility model: be provided with stripping attachment directly over described compensation fill block, and stripping attachment is adjacent with upper pressure block two.
In the utility model: the top of described upper pressure block two is provided with counterdie, and the below of the upper centre circle corresponding with counterdie is provided with patrix.
In the utility model: the top of described patrix side is provided with and cap, and cap is adjacent with Upper Die-sleeve, and wherein the below of patrix side is provided with fairlead, and being connected with fairlead is provided with pressing plate.
After adopting technique scheme, the beneficial effects of the utility model are: the utility model not only further increases prestressing force, decrease the risk of shaping mould radial direction cracking, improve the life-span of mould greatly, and consumptive material is few, cost is low, is beneficial to production in enormous quantities.
