Description
Technical field
The invention belongs to high temperature alloy precision casting field, more particularly to a kind of big riser running channel of large-sized high-temperature alloy casting
Cutting method.
Technical background
In recent years, with the development of aircraft industry, isothermal forging process has become prepares the powder turbine disk and titanium alloy change
The indispensable technique of shape part.During isothermal forging powder metallurgy superalloy, preparing for mould is extremely important.With mould cast
Size is increasing, and the size of riser is also increasing, and manufacturer is cut using cutting machine, but this also brings some problems.
On the one hand, part and Riser Dimensions are very big, and some riser diameters are more than 500mm, and part is in irregular shape, are loaded to cutting
Cutting mill is inconvenient, while requires corresponding blade radius bigger than the radius of riser, sometimes on the market without dimension
Saw blade, brings the problem of can not cutting；In addition, high-temperature alloy material itself is harder, cutting is difficult to carry out, right in operating process
The vibration of cutting machine is bigger, and the riser being cut is on high-speed rotating saw blade, there is the danger for flying out and hurting sb.'s feelings.
Using wire cutting mode, be loaded and the operation of part equally bring difficulty, while clipping time is grown, corresponding cutting
Cost can also increase；Using oxygen-acetylene torch cutting, this method causes the heat affected area of cut portion larger, in riser pad
Portion produces micro-crack, can not be cut for large-sized riser.Simultaneously as high temperature alloy aoxidizes sternly under high temperature fused state
Weight, cutting part and the material oxidation cut are serious, influence the clout recycling scaled off, cause the increase of production cost；Using gas
Planing skill is cut, and has the phenomenon of carburetting after cutting in riser, influences the recycling of material.
Therefore, operated using convenient, safe and reliable high-temperature alloy casting riser cutting method, become urgently to be resolved hurrily at present
The problem of.
The content of the invention
The purpose of present invention：For problem present in background technology, propose that a kind of large-sized high-temperature alloy casting emits
Mouth cutting method.
The technical scheme is that：A kind of cutting method of the big riser running channel of large-sized high-temperature alloy casting, including it is as follows
Step：
Casting is cooled to 150~200 DEG C by step 1) so that the cut surface of casting pressing port running channel is vertical with supporting surface, cuts
Direction is cut perpendicular to supporting surface；
Argon bottle tracheae is fixed in arc welder equipment by step 2) so that and tracheae nozzle is consistent with electrode wire direction,
Open arc-welding machine and argon bottle；
Step 3) is cut along cut surface, the protrusion surplus of 30mm is reserved in the initial position of cutting, and pour using riser
Road both sides are to the mode cut；
Cutting initial position of the step 4) to riser running channel is polished, and is heat-treated after polishing.
Further, wherein selection work electric current is 500A DC arc welding machines, selects nickel base alloy covered electrode, and welding rod is straight
Footpath is more than 4mm.
Preferably, in step 2) so that arc-welding machine operating current is 250~400A, and the outlet pressure of argon bottle is adjusted to 0.6
~1.0MPa.
Preferably, in step 3), for concentrating riser running channel, in riser running channel both sides either simultaneously or alternately to cutting；For dividing
Riser running channel is dissipated, using central symmetry position to cutting.
Beneficial effects of the present invention：High temperature alloy welding rod is selected, avoids bringing other impurity element into, effectively raises and cut
Cut the utilization of rear clout.By being blown into for argon gas, aluminium alloy in cutting process is cleared up in time, is avoided solidifying in cutting part accumulation
Gu improve cutting efficiency；Avoid producing oxide, be conducive to the recycling of clout；Cutting part is cooled down in time, is avoided big
The formation of heat affected area, ensures casting quality.Efficiently solve what large-sized high-temperature alloy die casting deformed by above-mentioned measure
Problem.
