Abstract

The forging molding mold of nuclear power hydraulic damper cylinder proper forgings is made of lower mold (1) and formed punch (2) two parts;The lower mold (1) is divided into cylindrical portions and square section part, and two-part cavity shape is different, and upper part is cylindrical shape, and lower part is rectangle, is respectively used to the cylindrical section and square plate section of molding cylinder proper forgings;Formed punch (2) gradient is 1.5 °, and formed punch (2) size is designed according to forging (4) blind hole size, for forming the cylindrical end blind hole position of cylinder proper forgings.The configuration of the present invention is simple, shaping speed is fast, accurate to dimension is high, machining allowance is small and overall performance is good.

Description

The forging molding mold of nuclear power hydraulic damper cylinder proper forgings
Technical field
The invention belongs to plastic forming technology fields, are related to the special manufacture of variable cross-section special-shaped product, in particular to nuclear power The forging molding mold of hydraulic damper cylinder proper forgings.
Background technique
Nuclear power hydraulic damper cylinder proper forgings are a kind of forging of typical variable cross-section shape, and one end is cylinder, separately One end is square plate, material 42CrMo4.
Forging cylinder shape Forging is usually used in cylinder proper forgings classical production process, then again will by mach mode One end is processed as square plate, and the other end is processed as cylinder.When manufacturing in this way, do not need using mold, but in material Portion's machine direction can be cut off in machining and reduce its comprehensive performance, and machining allowance is big, cause to machine working hour Increase, while will also result in the waste of raw material.
Summary of the invention
The purpose of the present invention is provide for the profile-followed forming method of nuclear power hydraulic damper cylinder body and same shape forging One set of die.
The forging molding mold of nuclear power hydraulic damper cylinder proper forgings is made of lower mold 1 and 2 two parts of formed punch;Institute It states lower mold 1 to divide for cylindrical portions and square section part, two-part cavity shape is different, and upper part is cylinder-shaped, lower part Dividing is rectangle, is respectively used to the cylindrical section and square plate section of molding cylinder proper forgings;
2 gradient of formed punch is 1.5 °, and 2 size of formed punch is designed according to 4 blind hole size of forging, for forming cylinder proper forgings Cylindrical end blind hole position.
By adopting the above technical scheme the utility model has the advantages that
The configuration of the present invention is simple, shaping speed is fast, accurate to dimension is high, machining allowance is small and overall performance is good.

Specific embodiment
In conjunction with above-mentioned attached Example, the present invention is further described.
Inventive die includes lower mold 1 and formed punch 2.
2 size of formed punch is designed according to forging blind hole size, and gradient is 1.5 °.
The lower mold 1 is made of two parts shape, and two-part cavity shape is different, and upper part is cylindrical shape, under Part is rectangle, is respectively used to the cylindrical section and square plate section of molding cylinder proper forgings.Lower mold cylindrical portion inner cavity shown in FIG. 1 Diameter D is that forging cylindrical section diameter adds this material heat expansion amount, and rectangle part thickness t is forging square plate section thickness t0+ heat is swollen Bulk+finishing surplus t0×5%。
Nuclear power hydraulic damper is as follows with cylinder proper forgings manufacturing process:
Steel ingot is heated first, is kept the temperature, Steel ingot feeder head end, ingot butt end non-densified regions are removed;Then by weight needed for forging Blanking is carried out, and by jumping-up, pulling deformation, to change its structural state, soldering internal flaw, then through round as a ball, sub-material, and One end is flattened, it is the variable cross-section blank 3 cylindrical, the other end is square plate type that one end, which is made,.
Variable cross-section blank 3 is put into lower mold and carries out jumping-up, makes its square plate end material full of mold;Then formed punch 2 is used Its cylindrical end is carried out to rush blind hole, is obtained and the consistent forging 4 of steel ingot product shape.
Forging 4 is taken out from lower mold 1, and finishing is carried out to forging surface, forging is made to reach desired size.
