Description

A kind of valve high temperature wear resistant coating mould
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of valve high temperature wear resistant coating mould.
Background technology
Valve hot forming tool adopts structure as shown in Figure 1 usually, and valve hot forming tool material generally adopts 3Cr2W8V.Because be thermoforming, having very high temperature during mould stock labour, in order to improve die life, is all in use adopt oil and graphite powder to be in harmonious proportion to carry out cooling, lubricating.However, the 3Cr2W8V mold use life-span is also undesirable, and die life is not ideal enough, and the single life-span is at 800 to 1000 times.And reparation comparatively bothers after wearing and tearing, need to carry out rough turn, finish turning, polishing, and mould repair once after entire life simultaneously in shortening, (mold height change); Can produce very large oil smoke in graphite oil cooling procedure during work, damage human body, working environment is very severe.
Utility model content
The utility model additionally provides a kind of valve high temperature wear resistant coating mould, when using this mould to produce valve, mould does not need graphite oil to cool, good work environment, die life is long, decreases the reparation number of times of mould and improves the surface roughness of valve blank.
The technical solution adopted in the utility model is for this reason: the utility model comprises die ontology (1) and is opened in the mold cavity (2) in die ontology (1), and described die ontology (1) comprises matrix (11) and is arranged on matrix grey black nitrogenize high alumina titanium PVD coating (12) of matrix (11) outer surface; Described mold cavity (2) comprises matrix die cavity (22) and is arranged on matrix die cavity grey black nitrogenize high alumina titanium PVD coating (21) of matrix die cavity (22) inner surface.
Described matrix (11) material is H13 steel alloy.
A processing technology for valve high temperature wear resistant coating mould, carry out according to following steps:
1) blank carries out ten upsettings ten and pulls out and forge;
2) anneal: be warmed up to 850 DEG C ± 10 DEG C, insulation, then open fire door, after blank drops to 750 DEG C ± 10 DEG C, then be incubated, stove is as cold as 530 DEG C-550 DEG C and comes out of the stove, and room temperature cools;
3) roughing is carried out;
4) quench under the condition of 1050 DEG C;
5) Air flow after workpiece is cooled to 350-400 DEG C in quenching oil after heating;
6) tempering: adopt 600-650 DEG C of tempering three times;
7) fine finishining is shaping;
8) mold cavity surface carries out finishing polish process;
9) mold clean integral surface nitrogenize high alumina titanium PVD coating process.
Described 9) in step: matrix (11) outer surface and matrix die cavity (22) inner surface adopt nitrogen in glow discharge plasma to diffuse in delamination by nitrogenize high alumina titanium PVD coating.
Described coating layer thickness is 1-4 μm.
The utility model has the advantages that: high temperature wear resistant coating is grey black nitrogenize high alumina titanium PVD coating, because the composition containing aluminium is high, so its heat resistanceheat resistant performance is high, hardness is more than 1800HV, and thickness is 1-4 μm, and coefficient of friction is 0.7,900 DEG C time, there is higher shock resistance, extend the mold use life-span, decrease the die change number of times of workman, improve production efficiency; When using this mould to produce, do not need graphite oil to cool yet, improve working environment; Also need only carry out polishing and surface modification treatment to mould repair, repair also more easy, reduce the material cost of mould.
Matrix surface and cavity inner surface adopt nitrogen in glow discharge plasma to diffuse in delamination by nitrogenize high alumina titanium PVD coating, thus the processes strengthening surface of the work hardness and anti-wear performance forms, hardness is at more than 1800HV, there is higher shock resistance, because nitrogenize high alumina titanium PVD coating top layer obtains less hard particles, thus there is higher antiwear property, extend the mold use life-span, decrease the die change number of times of workman, improve production efficiency.
