Abstract
The present invention relates to valve lifters of internal combustion engines extrusion die, including: ejector beam 1, base 2, lower punch cushion block 3, push rod 4 guide plate 5, shrink ring 6, die 7, punch 8, guide pillar 9, upper cushion block 10, upper male mould cushion block 11, cope match-plate pattern 12 guide pin bushing 13, clamping block 14, upper male mould locating piece 15, stop collar 16, gland 17, extrusion 18, lower bolster 19, sleeve 20, lower shoe 21, ejector beam base plate 22, this combined die uses cold-press method, it is 1 ° 30 ' that angle is closed in pressure, colouring inspection is used when the grinding conical surface, ensure internal layer and middle level, middle level is all higher than 85% with the contact area of outer layer, die inner layer material selects W18Cr4V, heat treatment hardness HRC60～65；Middle level shrink ring material selection 40Cr, heat treatment hardness HRC40～45；Outer layer shrink ring material selection 40Cr or 45# steel, heat treatment hardness is HRC40～42, and this technique has saved a large amount of raw material and machining period, improves the mechanical performance of product, thus greatly strengthen the competitiveness of product in market.
Description
Technical field
The invention belongs to mould applications, be specifically related to valve lifters of internal combustion engines extrusion die.
Background technology
Owing to internal combustion engine has Multiple Type, therefore, the tappet matched therewith also has Multiple Type, and tappet is main group of valve actuating mechanism
Become part, be to utilize engine oil pressure that the power on eccentric on camshaft is delivered to the mechanism of valve,.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, long-lived gasoline filter.
Valve lifters of internal combustion engines extrusion die, it is characterised in that including: ejector beam, base, lower punch cushion block, push rod guide plate,
Shrink ring, die, punch, guide pillar, upper cushion block, upper male mould cushion block, cope match-plate pattern, guide pin bushing, clamping block, upper male mould position
Block, stop collar, gland, extrusion, lower bolster, sleeve, lower shoe, ejector beam base plate, this combined die employing cold-press method,
Pressure is closed angle and is 1 ° 30 ', uses colouring inspection when the grinding conical surface, ensures that internal layer connects with outer layer with middle level, middle level
Contacting surface is long-pending is all higher than 85%, and die inner layer material selects W18Cr4V, heat treatment hardness HRC60～65；Middle level shrink ring material choosing
With 40Cr, heat treatment hardness HRC40～45；Outer layer shrink ring material selection 40Cr or 45# steel, heat treatment hardness HRC40～
42。
The invention have the benefit that the mould highly versatile of the present invention, only need to change a small amount of mould parts, so that it may extrude multiple type
Number valve lifter.This technique has saved a large amount of raw material and machining period, improves the mechanical performance of product, thus is greatly enhanced
The competitiveness of product in market.
