Abstract
The invention relates to an air valve alloyed forming die. The forming die is characterized in that a die body is composed of a matrix and a YG8 hard alloy cavity embedded in the matrix, a die cavity is composed of a cavity and a matrix cavity, and the cavity is made of YG8 hard alloy with hardness of HRC70-74 and high impact resistance, so that the service life of the die is prolonged, the number of times for die changing is reduced for workers, and production efficiency is improved; during production using the die, cooling by graphite oil is not needed, so that working environment is improved; and only polishing is needed for die repairing, so that repairing is simpler and more convenient. In addition, the YG8 hard alloy is expensive, and an embedded structure is adopted, so that consumption of the YG8 hard alloy is reduced, and material cost of the die is lowered; and a method of heating a die sleeve and pressing the YG8 cavity into the die sleeve is adopted for interference fit, and upper and lower end faces of the die are grinded properly after cooling to guarantee parallelism of upper and lower planes so as to be used.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of air valve alloy and change into mould.
Background technology
The valve hot forming tool adopts structure as shown in Figure 1 usually, and valve hot forming tool material generally adopts H13(4Cr5MoSiV1).Because be thermoforming, mould has very high temperature, in order to improve die life, be all in use adopt oil and graphite powder to be in harmonious proportion to carry out cooling, lubricate.However, the H13 mold use life-span is also undesirable, repairs comparatively trouble after mould uses, need to carry out finish turning, polishing and tufftride and process, and mould repair once after, mould also can only be worked at most 1500, mould will again be repaired or scrap; Can produce very large oil smoke in the graphite oil cooling procedure, human body is damaged, working environment is very abominable.
Summary of the invention
The present invention also provides a kind of forming mould for air valve, and when using this mould to produce valve, mould does not need graphite oil cooling, good work environment, and die life is long, has reduced the reparation number of times and the surface roughness that has improved valve blank of mould.
For solving the problems of the technologies described above, forming mould for air valve of the present invention, die ontology is comprised of matrix and the YG8 carbide alloy cavity that embeds described matrix, and described mold cavity is comprised of cavity die cavity and matrix die cavity.
Cavity cavity material of the present invention is the YG8 carbide alloy, and hardness has higher shock resistance at HRC70-74, has extended the mold use life-span, has reduced workman's die change number of times, has improved production efficiency; When using this mould to produce, do not need graphite oil cooling yet, improved working environment; Also need only carry out polishing to mould repair, repair also more easy.Simultaneously, because the YG8 carbide alloy is more expensive, adopt damascene structures, reduced the consumption of YG8 Hardmetal materials, reduced the material cost of mould.The heating of employing die sleeve, then the method that the YG8 cavity is pressed in die sleeve is carried out interference fit, wait cooling rear upper and lower end face to mould to carry out suitable grinding, in assurance, the depth of parallelism of lower plane, come into operation.
Description of drawings
Fig. 1 is air valve alloy mould of the present invention.
Fig. 2 is background technology H13 die shape.
In figure, 1 is that die ontology, 11 is that matrix, 12 is that cavity, 2 is that mold cavity, 21 is that cavity die cavity, 22 is the matrix die cavity.
The specific embodiment
The present invention is further detailed explanation with concrete mode below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, forming mould for air valve of the present invention, comprise die ontology 1 and mold cavity 2, described die ontology 1 is comprised of the cavity 12 of matrix 11 and the described matrix 11 of embedding, described mold cavity 2 is comprised of cavity die cavity 21 and matrix die cavity 22, and described cavity 12 is processed by the method for YG8 carbide alloy according to processing forming mould for air valve described above.
One, die sleeve processing method:
(1) blank carries out ten upsettings ten and pulls out and forge;
(2) annealing: after being warmed up to 860 ℃, then insulation opens fire door, after blank drops to 750 ℃, then insulation, stove is as cold as 500 ℃-550 ℃ and comes out of the stove, and room temperature is cooling;
(3) carry out roughing;
(4) 1050 ℃ of quenchings; (5) after after the heating, workpiece is cooled to 350-400 ℃ in quenching oil, air is cooling;
(6) tempering: adopt 600-650 ℃ of tempering three times;
(7) fine finishining.
Two, cavity processing method:
(1) adopt the electric pulse processing method that die cavity is shaped on the YG8 carbide alloy of buying given size;
(2) inside cavity is carried out polishing.
Three, fitting method:
(1) die sleeve that processes is put into well formula resistance furnace heating about 2 hours, the taking-up of 300 degree;
(2) cavity is pressed into rapidly in die sleeve, carries out air cooling;
(3) mould of working good is carried out the grinding of two ends, up and down, guarantee the depth of parallelism of both ends of the surface;
(4) die cavity of mould carried out the finishing polish processing.
Claims (1)
1. an air valve alloy changes into mould, it is characterized in that, described die ontology (1) is comprised of the YG8 carbide alloy cavity (12) of matrix (11) and the described matrix of embedding, and described mold cavity (2) is comprised of cavity die cavity (21) and matrix die cavity (22).
