Description

The mould of nuclear power hydraulic damper cylinder body forging

Technical field

The utility model belongs to the technical field of forging in machine-building, the mould of particularly a kind of nuclear power hydraulic damper cylinder body forging.

Background technology

Nuclear power hydraulic damper cylinder body is a kind of one end is cylindrical and with blind round hole, the other end side of being flat part, in the use procedure of nuclear power field, generally need after forging processing, its performance just can meet the demands, but complex-shaped due to this part, forging and molding difficulty is large, current fabrication scheme is generally: first blank is forged into cylinder, then be worked into by the mode of machining and finally require size, this fabrication scheme consumption of raw materials is many, long processing time, product cost is higher, simultaneously, the metal streamline of forging is easily cut off when machining, be unfavorable for the final utilization of this product, therefore, a kind of special mould need be designed, enable product with shape forging, high to reduce nuclear power hydraulic damper cylinder body manufacturing cost, solve the discontinuous drawback of resultant metal streamline.

Utility model content

The purpose of this utility model is the forging method for existing manufacture nuclear power hydraulic damper cylinder body, there is the problems such as manufacturing cost is high, resultant metal streamline is discontinuous, the mould of a kind of nuclear power hydraulic damper cylinder body forging is provided, this device is adopted to make nuclear power hydraulic damper cylinder body can with shape forging, simple to operate, production efficiency is high, low cost of manufacture, and resultant metal streamline is continuous.

The technical solution of the utility model is:

A mould for nuclear power hydraulic damper cylinder body forging, primarily of base, collar composition, the collar is welded on base, and the rectangular cavity that base is established and the circular cavity of the collar form molding cavity.

Further, described base is T-shaped shape, is welded form by the half T-shaped pedestal that two pieces is symmetrical.

Mould in the utility model in use, first adopt conventional forging method forging cylinder, and ultrasonic examination is carried out in roughing, guarantee ultrasonic examination is qualified, obtained cylinder blank, again cylinder blank heating is incubated to forging temperature, with one end of press operation machine clamping cylinder blank after coming out of the stove, the other end of cylinder blank is flattened, then flat square end is put into the building mortion of the utility model down, make its collar of fitting with the cylindrical end of press cylinder upset blank again, then cylindrical end blind round hole is rushed to the size required with drift, after forging is taken out mould, press operation machine clamps cylindrical end, pull out flat square end again to the size required, i.e. obtained nuclear power hydraulic damper cylinder proper forgings.

The beneficial effects of the utility model and advantage are:

Utilize that Mould operation cylinder list of the present utility model, production efficiency are high, forging can with shape forging, the metal streamline of forging is continuous, good product quality, and mould structure of the present utility model is simple, manufactures processing cost low, is conducive to applying.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail, but should not be interpreted as that the scope of theme described in the utility model is only limitted to following embodiment at this point, do not departing from the above-mentioned technological thought situation of the utility model, all make according to ordinary skill knowledge and customary means various amendments, replacement and change, include in scope of the present utility model.

As shown in Fig. 1 to 7, nuclear power hydraulic damper cylinder body 1 is a kind of one end is cylindrical and with blind round hole 7, the other end side of being flat part, complex-shaped due to this part, forging and molding difficulty is large.For solving nuclear power hydraulic damper cylinder body 1 forging process Problems existing, the utility model design provides the mould of a kind of nuclear power hydraulic damper cylinder body forging, and concrete scheme is:

This mould forms primarily of primarily of base 2, the collar 3, and the collar 3 is welded on base 2, and the rectangular cavity 4 that base 2 is established forms molding cavity with the circular cavity 5 of the collar 3.

Further, described base 2 is T-shaped shape, is welded form by the half T-shaped pedestal that two pieces is symmetrical.

When mould in the utility model uses, first adopt conventional forging method forging cylinder, and ultrasonic examination is carried out in roughing, guarantee ultrasonic examination is qualified, obtained cylinder blank 6, again cylinder blank 6 is heated under initial forging temperature, insulation, with one end of press operation machine clamping cylinder blank 6 after coming out of the stove, the other end of cylinder blank 6 is flattened, then flat square end is put into the rectangular cavity 4 of the base 2 of the utility model building mortion down, again with the cylindrical end of press cylinder upset blank 6 and the collar 3 making it fit, then with the blind round hole 7 of drift punching cylindrical end to requiring size, after forging is taken out mould, press operation machine clamps cylindrical end, pull out flat square end again to the size required, the i.e. forging of obtained nuclear power hydraulic damper cylinder body 1.

Claims

1. the mould of nuclear power hydraulic damper cylinder body forging, primarily of base (2), the collar (3) composition, it is characterized in that the described collar (3) is welded on base (2), the molding cavity that the rectangular cavity (4) that base (2) is established is formed with the circular cavity (5) of the collar (3).

2. the mould of a kind of nuclear power hydraulic damper cylinder body according to claim 1 forging, is characterized in that at described base (2) be T-shaped shape, is welded form by the half T-shaped pedestal that two pieces is symmetrical.
