Abstract

The present invention relates to a kind of preparation methods of superalloy annular forging expanding die, it is characterized in that, the expanding die preparation process is as follows: jumping-up, punching are hollow ring billet after heating stainless steel bars to deformation temperature, after heating hollow ring billet to forging temperature, by hollow ring billet reaming for an outer profile and to the consistent annular element of superalloy annular forging inner ring facial contour of bulging;Annular element is heat-treated, anchor ring carries out after machine adds inside and outside it, divides valve for what annular element was cut into muti-piece same specification.The present invention adds the technique of cutting to prepare using looping mill rolling+machine, it is consistent with the inner ring surface section of high temperature alloy ring to bulging that an outer ring surface section is prepared for by looping mill rolling, and inner ring surface section is the special-shaped ring of rectangle, then thermally treated, internal outer ring surface carries out a small amount of machine and adds, and then carries out cutting.When greatly reducing machining using this technique and the waste of mold materials, the manufacturing cost of expanding die is reduced.

Description

A kind of preparation method of superalloy annular forging expanding die

Technical field

Reaming is rolled and machine adds the method for cutting to prepare for the forming of high temperature alloy ring heat expansion the present invention relates to a kind of Expanding die.

Background technique

The method for the expanding die for preparing superalloy annular forging at present has: directlying adopt biscuit machine and adds or pass through upsetting It is a rectangular section annular forging piece that the techniques such as cake, punching and reaming, which obtain, and then machine adds cutting.Using the technique, there are machines to add The problems such as working hour is long, mold materials utilization rate is low.It thus provides a kind of efficiently prepare anisotropic superalloy annular forging bulging The method of mold.

Summary of the invention

The object of the present invention is to provide a kind of using cerclage+machine, and to add the technique of cutting swollen to prepare high temperature alloy opposite sex ring The method of shape mold when can be shortened machining using this method, reduces the waste of mold materials, and is able to satisfy high temperature alloy ring The requirement of bulging.

To solve the above problems, the present invention efficiently prepares high temperature alloy expanding die method and adopts the following technical solutions It realizes:

A kind of preparation method of superalloy annular forging expanding die, the expanding die preparation process are as follows: heating Jumping-up, punching are hollow ring billet after stainless steel bars to deformation temperature, after heating hollow ring billet to forging temperature, by hollow ring billet Reaming is an outer profile and the consistent annular element 1 of superalloy annular forging inner ring facial contour to bulging;By annular element 1 into Row heat treatment, anchor ring carries out after machine adds inside and outside it, divides valve 2 for what annular element 1 was cut into muti-piece same specification.

Specific step is as follows: step 1: jumping-up is heated to deformation temperature according to the stainless steel bars of expanding die specification blanking Then degree carries out jumping-up in quick forging machine;Step 2: the biscuit after jumping-up is gone out centre bore with formed punch in quick forging machine and obtained by punching To hollow ring billet;Step 3: looping mill rolling, the hollow ring billet that step 2 is obtained are heated to place horizontal diameter axial direction looping mill rolling after deformation temperature Roll off on machine makes the continuous and local deformation that hollow ring billet carries out inner hole increase, wall thickness reduces, outer diameter increases, obtains an outer ring Face section with to the consistent annular element 1 in bulging superalloy annular forging inner ring surface section;Step 4: cutting, the annular that will be obtained 1 carry out machine of part adds, then divides valve 2 for what annular element 1 was cut into muti-piece same specification.

Preferably, the inner ring surface of annular element 1 described in step 3 is rectangle.The process of step 4 cutting is as follows: drawing one and ring The auxiliary circle that shape part 1 is with one heart, diameter is 100mm, 12 equal branches are then determined in auxiliary circle, are with each equal branch Point does the cutting line that two angles are 30 °, by the uniform cutting of annular element 1 is that 12 pieces of same specifications divide valve 2, and will divide valve 2 with to The superalloy annular forging of bulging is coupled in the bulging on shape expanding machine, for high-temperature alloy special-shaped ring.

It is compared with the prior art, beneficial effects of the present invention are as follows:

The preparation method of high temperature alloy ring expanding die of the present invention, using the work for adding cutting using looping mill rolling+machine Prepared by skill, it is with the inner ring surface section of high temperature alloy ring to bulging consistent to be prepared for an outer ring surface section by looping mill rolling, And inner ring surface section is the special-shaped ring of rectangle, then thermally treated, internal outer ring surface carries out a small amount of machine and adds, and is then cut Point.When greatly reducing machining using this technique and the waste of mold materials, the manufacturing cost of expanding die is reduced.

Detailed description of the invention

Invention is further described in detail with reference to the accompanying drawings and detailed description.

Fig. 1 is stainless steel annular element schematic diagram.

Fig. 2 carries out wire cutting cutting to stainless steel annular element.

Specific embodiment

Implement the preparation method of high-temperature alloy special-shaped annular forging piece heat expansion shaping dies of the present invention, it is desirable to provide forging Part heating furnace, quick forging machine, staving press and stainless steel bars.Fig. 1 is that machine adds expanding die schematic diagram.

Step 1: jumping-up.It is heated to deformation temperature according to the stainless steel bars of expanding die specification blanking, is then being forged fastly Machine carries out jumping-up.

Step 2: punching.Biscuit after jumping-up is rushed into thick centre bore with formed punch in quick forging machine and obtains hollow ring billet.

Step 3: looping mill rolling.The hollow ring billet that step 2 is obtained is heated to place horizontal diameter axial direction looping mill after deformation temperature Upper roll off makes the continuous and local deformation that hollow ring billet inner hole increases, wall thickness reduces, outer diameter increases, obtains an outer ring surface section It is consistent with to bulging ring inner ring surface section, and inner ring surface is the annular element 1 of rectangle.

Step 4: cutting.Obtained stainless steel ring is subjected to cutting.Dicing process are as follows: draw one with annular element 1 it is concentric, Diameter is the auxiliary circle of 100mm, then determines that 12 equal branches make two folders using each equal branch as starting point in auxiliary circle Angle is 30 ° of cutting line, by the uniform cutting of annular element 1 is that 12 pieces of same specifications divide valve 2, and will divide valve 2 with to the high temperature of bulging Alloy annular forging is coupled in the bulging on shape expanding machine, for high-temperature alloy special-shaped ring.
